The server provides OpenAI‑compatible APIs and mature AuthNZ (single‑user API key and multi‑user JWT modes). + +## Goals +- Deliver an integrated research assistant in the browser that: + - Chats via `/api/v1/chat/completions` with streaming and model selection. + - Searches via RAG (`/api/v1/rag/search` and `simple` if exposed). + - Ingests content (current page URL or manual URL) via `/api/v1/media/process` and related helpers. + - Manages notes and prompts through their REST endpoints. + - Transcribes audio via `/api/v1/audio/transcriptions`; synthesizes speech via `/api/v1/audio/speech`. +- Provide smooth setup (server URL + auth) and a robust, CORS‑safe network layer. +- Ship an MVP first and iterate with clear milestones. + +## Non‑Goals +- Building a general proxy for arbitrary third‑party LLM services. +- Adding server features not exposed by tldw_server APIs. +- Collecting telemetry on user content or behavior. + +## Personas +- Researcher/Student: Captures web content, asks questions, organizes notes. +- Developer/Analyst: Tries multiple models/providers, tweaks prompts, exports snippets. +- Power user: Uses voice (STT/TTS), batch ingest, and RAG filters. + +## User Stories (MVP‑critical) +- As a user, I configure the server URL and authenticate (API key or login). +- As a user, I see available models/providers and select one for chat. +- As a user, I ask a question and receive streaming replies with cancel. +- As a user, I search with RAG and insert results into chat context. +- As a user, I send the current page URL to the server for processing and get status. +- As a user, I quickly capture selected text as a note and search/export notes. +- As a user, I upload a short audio clip for transcription and view the result. + +## Scope + +### MVP (v0) +- Settings: server URL, auth mode (single/multi), credentials, health check. +- Auth: X‑API‑KEY and JWT (login/refresh/logout); error UX for 401/403. +- Models: discover and select model/provider from server. +- Chat: non‑stream and SSE stream; cancel; basic local message history. +- RAG: simple search UI; insert snippets into chat context. +- Media: ingest current tab URL or entered URL; progress/status. +- Notes/Prompts: basic create/search/import/export. +- STT: upload wav/mp3/m4a; show transcript. + +### v1 +- TTS playback; voice catalog/picker. +- Context menu “Send to tldw_server”. +- Improved RAG filters (type/date/tags). +- Robust error recovery and queued retries. + +### v1.x +- Batch operations; offscreen processing where safe. +- MCP surface (if required later). + +## Functional Requirements + +### Settings and Auth +- Allow any `serverUrl` (http/https); validate via a health check. +- Modes: Single‑User uses `X-API-KEY: `. Multi‑User uses `Authorization: Bearer `. +- Manage access token in memory; persist refresh token only when necessary. +- Auto‑refresh on 401 with single‑flight queue; one retry per request. +- Never log secrets; redact sensitive fields in errors. + +### Network Proxy (Background/Service Worker) +- All API calls originate from background; UI/content never handles tokens directly. +- Optional host permissions per configured origin at runtime; least privilege. +- SSE support: set `Accept: text/event-stream`, parse events, keep‑alive handling, `AbortController` cancellation. +- Timeouts with exponential backoff (jitter). Offline queue for small writes. + +### API Path Hygiene +- Match the server’s OpenAPI exactly, including trailing slashes where specified, to avoid redirects and CORS quirks. +- Core endpoints: + - Chat: `POST /api/v1/chat/completions` + - RAG: `POST /api/v1/rag/search` (and `/rag/simple` if exposed) + - Media: `POST /api/v1/media/process` + - Notes: `/api/v1/notes/...` (search may require a trailing slash;

do not rely on client‑side redirects. + +### Chat +- Support `stream: true|false`, model selection, and OpenAI‑compatible request fields. +- Pause/cancel active streams; display partial tokens. +- Error UX: connection lost, server errors, token expiration. + +### RAG +- Query field, minimal filters; result list with snippet, source, timestamp. +- Insert selected snippets into chat as system/context or user attachment. + +### Media Ingestion +- Current tab URL ingestion; allow manual URL input. +- Show progress/toasts and final status; handle failures gracefully. + +### Notes and Prompts +- Create note from selection or input; tag and search. +- Browse/import/export prompts; insert prompt into chat. + +### STT +- Upload short audio (<= 25 MB MVP); show transcript with copy. +- Validate mime types; surface server validation errors. + +### TTS (v1) +- Voice list fetch; synthesize short text; playback controls; save last voice. + +## Non‑Functional Requirements + +### Security & Privacy +- No telemetry; no content analytics; local‑only diagnostics toggled by user. +- Keep access tokens in memory in background; persist refresh tokens only if required. +- Never expose tokens to content scripts; sanitize logs. + +### Performance +- Background memory budget < 50 MB steady‑state. +- Chat stream first token < 1.5s on LAN server. +- Bundle size targets: side panel < 500 KB gz (MVP); route‑level code splitting. + +### Reliability +- Resilient to server restarts; retries with backoff; idempotent UI state. +- Offline queue for small writes (e.g., notes) with visible status. + +### Compatibility +- Chrome/Edge MV3 using service worker; Firefox MV2 fallback. +- Feature‑detect offscreen API; don’t hard‑rely on it. + +### Accessibility & i18n +- Keyboard navigation, ARIA roles for side panel. +- Strings ready for localization; English default. + +## Architecture Overview + +### Background/Service Worker +- Central fetch proxy, SSE parsing, retries, 401 refresh queue, permission prompts. + +### UI Surfaces +- Side panel (chat, RAG, notes/prompts, STT/TTS). +- Options page (server/auth/settings). +- Popup (quick actions/status). + +### Content Script +- Selection capture; page metadata for ingest; no secret handling. + +### State & Storage Policy +- Background state store; message bus to UIs; `chrome.storage` for non‑sensitive prefs. +- Do not store user content by default beyond session state. +- Optional local cache for small artifacts with TTL and user clear. + +## CORS & Server Config +- Prefer background‑origin requests with explicit `host_permissions`/`optional_host_permissions`. +- Server should allow CORS for the extension origin; for dev, wildcard allowed on localhost. +- Avoid blocking `webRequest` in MV3; use direct fetch and headers in background. + +## Success Metrics +- 80%+ users complete setup within 2 minutes. +- < 5% request error rate in normal operation. +- Streaming starts within 1.5s on LAN; steady memory < 50 MB. +- > 90% of API paths hit without 307 redirects (path hygiene). + +## Milestones and Deliverables + +### Milestone 1: Connectivity & Auth (Week 1–2) +- Options page with server URL and auth. +- Background proxy with health check. +- Acceptance: Successful health ping; auth tokens handled; 401 refresh working. + +### Milestone 2: Chat & Models (Week 3–4) +- Fetch providers/models; chat non‑stream and stream; cancel. +- Acceptance: Streaming chat across at least two models; SSE cancel; exact path matching. + +### Milestone 3: RAG & Media (Week 5–6) +- RAG search with snippet insertion; URL ingest with progress. +- Acceptance: RAG returns results; snippet insert; ingest completes with status notifications. + +### Milestone 4: Notes/Prompts & STT (Week 7–8) +- Notes CRUD + search; prompts browse/import/export; STT upload/transcribe. +- Acceptance: Notes searchable; prompts import/export; successful transcript for a ~20s clip. + +### Milestone 5: TTS & Polish (Week 9–10) +- TTS synthesis/playback; voice list; UX polish and accessibility checks. +- Acceptance: Voice picker works; playable audio from `/api/v1/audio/speech`. + +## Acceptance Criteria (Key) +- Path Hygiene: All requests hit exact API paths defined by OpenAPI; no 307s observed in logs. +- Security: Tokens never appear in UI or console logs; content scripts lack access to tokens. +- SSE: Streaming responses parsed without memory leaks; cancel stops network within ~200ms. +- Retry/Refresh: 401 triggers single‑flight refresh; queued requests replay once; exponential backoff with jitter for network errors. +- Permissions: Optional host permissions requested only for user‑configured origin; revocation handled gracefully. +- Media: Ingest current tab URL; show progress and final status; errors actionable. +- STT/TTS: Supported formats accepted; errors surfaced with clear messages. + +## Dependencies +- Server availability and correct CORS config. +- Accurate OpenAPI spec and stability of endpoints. +- Browser APIs: `storage`, `side_panel`, `contextMenus`, `notifications`, `offscreen` (optional), message passing. + +## Risks & Mitigations +- Endpoint variance (e.g., trailing slashes): Centralize route constants; validate against OpenAPI on startup and warn. +- Large uploads: Enforce size caps in UI; add chunking later if required. +- Firefox MV2 constraints: Document broader host permissions; polyfill SSE parsing if needed. + +## Out of Scope (for MVP) +- Full chat history sync with server. +- Advanced MCP tools integration. +- Batch operations and resumable uploads. + +## Open Questions +- Confirm canonical API key header name: proceeding with `X-API-KEY`.

+# Evaluations Module
+
+Note: This README is aligned to the project’s 3-section template. The original README content is preserved below unchanged to avoid any loss of information or diagrams.
+
+## 1. Descriptive of Current Feature Set
+
+The Evaluations module provides a unified, API- and CLI-driven system for model benchmarking and evaluation. It supports OpenAI-compatible workflows and tldw-specific evaluators, plus datasets/runs management, webhooks, rate limiting, and embeddings A/B tests.
+
+- Capabilities
+  - Unified evaluations: model-graded, exact/includes/fuzzy match, GEval, RAG, response quality, propositions, OCR, label_choice, nli_factcheck
+  - Datasets and runs: CRUD, pagination, idempotent create/run, run cancellation, history
+  - Embeddings A/B testing: create/run tests, status/results, significance, reranker toggles
+  - Webhooks: registration, status, test helpers; delivery metrics
+  - Rate limits and admin tools: per-user guards; idempotency key cleanup
+
+- Inputs/Outputs
+  - Input: JSON requests per evaluation type (see schemas); optional idempotency via `Idempotency-Key`
+  - Output: structured responses (scores/metrics/results); streaming available where applicable
+
+- Related Endpoints (examples)

+
+## 2. Technical Details of Features
+
+- Architecture & Flow
+  - Unified router aggregates CRUD, run management, evaluator-specific routes, webhooks, rate limits, admin ops
+  - Service layer: `unified_evaluation_service.py` orchestrates evaluators, DB adapters, and async work
+  - Evaluation types map to dedicated evaluators (e.g., `rag_evaluator.py`, `response_quality_evaluator.py`, `ocr_evaluator.py`)
+
+- Key Components
+  - Service & managers: `unified_evaluation_service.py`, `evaluation_manager.py`, `webhook_manager.py`, `user_rate_limiter.py`
+  - Evaluators/utilities: `rag_evaluator.py`, `ms_g_eval.py`, `simpleqa_eval.py`, `metrics.py`, `metrics_advanced.py`
+  - Embeddings A/B: `embeddings_abtest_service.py`, `embeddings_abtest_repository.py`
+  - Infra: `connection_pool.py`, `db_adapter.py`, `circuit_breaker.py`
+
+- Database & Storage
+  - DB manager: `DB_Management/Evaluations_DB.py` with optional PostgreSQL backend and RLS policies
+  - Per-user DB paths via `db_path_utils.DatabasePaths.get_evaluations_db_path(user_id)`
+  - Idempotency store for evaluations/runs/A/B tests; admin cleanup endpoint available
+
+- Configuration & AuthNZ
+  - Rate limits: `evaluations_auth.check_evaluation_rate_limit`; per-user limits + `GET /rate-limits`
+  - RBAC: `rbac_rate_limit`, `require_token_scope` on sensitive endpoints; admin checks for A/B runs and cleanup
+  - Idempotency: `Idempotency-Key` header for create/run endpoints; replay indicated via `X-Idempotent-Replay`
+  - Test overrides: `EVALUATIONS_TEST_DB_PATH` to redirect DB in tests; single-user vs multi-user logic
+
+- Concurrency & Performance
+  - Async evaluators; background tasks for long-running processes (A/B runs)
+  - Connection pooling and circuit breakers; streaming where supported
+
+- Error Handling & Security
+  - Standardized error responses via `create_error_response`; input sanitization in schemas
+  - Webhook delivery tracking, retries, and stats; safe URL handling and secrets
+
+## 3. Developer-Related/Relevant Information for Contributors
+
+- Folder Structure (high-level)
+  - `Evaluations/` — evaluators, services, metrics, CLI, benchmark registry/loaders
+  - `Evaluations/cli/` — CLI commands (`tldw-evals`)
+  - `Evaluations/configs/` — example configs and templates
+
+- Extension Points
+  - Add a new evaluator: implement in `Evaluations/` and register in service/registry
+  - Add endpoints: extend `evaluations_unified.py` (or split modules) and add schemas
+  - Extend A/B: update `embeddings_abtest_service.py` + schemas; update repository queries
+
+- Tests (useful suites)
+  - Integration/API: `tldw_Server_API/tests/Evaluations/integration/test_api_endpoints.py`
+  - Unified/e2e: `tldw_Server_API/tests/Evaluations/test_evaluations_unified.py`, `tldw_Server_API/tests/e2e/test_evaluations_workflow.py`
+  - OCR/RAG/Propositions: `tldw_Server_API/tests/Evaluations/test_ocr_metrics.py`, `test_rag_pipeline_runner.py`, `test_proposition_evaluations.py`
+  - A/B tests: `tldw_Server_API/tests/Evaluations/test_embeddings_abtest_idempotency.py`, `embeddings_abtest/test_scaffold.py`
+  - DB/CRUD (Postgres+SQLite): `tldw_Server_API/tests/Evaluations/test_evaluations_postgres_crud.py`, `tests/DB_Management/test_evaluations_unified_and_crud.py`
+
+- Local Dev Tips
+  - Install extras: `pip install -e .[evals]`
+  - Use `Idempotency-Key` during repeated runs in dev/testing
+  - `TESTING=1` may force sync paths for some long-running A/B flows
+
+- Docs
+  - User Guide: `tldw_Server_API/app/core/Evaluations/EVALS_USER_GUIDE.md`
+  - Developer Guide: `tldw_Server_API/app/core/Evaluations/EVALS_DEVELOPER_GUIDE.md`

 **Chatbooks Module**
 
+Note: This README is aligned to the project’s 3-section template. The original content is preserved below under section 3 to avoid any loss of information.
+
+## 1. Descriptive of Current Feature Set
+
+- Purpose: Export, import, preview, and manage user content as portable chatbooks (ZIP + manifest), with multi-user isolation, quotas, and async job processing.
+- Capabilities:
+  - Sync/async export and import with robust validation and sanitization
+  - Signed download URLs (optional), per-user storage roots, job tracking
+  - Quotas (storage, daily ops, concurrency, file caps) and health checks
+- Inputs/Outputs:
+  - Input: JSON requests for export/import/preview; file upload for import
+  - Output: Job metadata, manifest preview, and downloadable ZIPs
+- Related Endpoints (selected):
+  - Router: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:52 (prefix `/api/v1/chatbooks`)
+  - GET `/health`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:67
+  - POST `/export`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:119
+  - POST `/import`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:303
+  - POST `/preview`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:513
+  - GET `/export/jobs`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:686
+  - GET `/import/jobs`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:794
+  - GET `/download/{job_id}`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:896
+  - POST `/cleanup`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:1067
+  - DELETE `/export/jobs/{job_id}`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:1114
+  - DELETE `/import/jobs/{job_id}`: tldw_Server_API/app/api/v1/endpoints/chatbooks.py:1156
+- Related Schemas:
+  - tldw_Server_API/app/api/v1/schemas/chatbook_schemas.py:70 (`CreateChatbookRequest`), :242 (`CreateChatbookResponse`)
+  - tldw_Server_API/app/api/v1/schemas/chatbook_schemas.py:108 (`ImportChatbookRequest`), :251 (`ImportChatbookResponse`)

+  - tldw_Server_API/app/api/v1/schemas/chatbook_schemas.py:193 (`ExportJobResponse`), :211 (`ImportJobResponse`)
+
+## 2. Technical Details of Features
+
+- Architecture & Flow:
+  - API → Service (`chatbook_service.py`) → Validators/Quota → ZIP/manifest I/O → Jobs backend (core or Prompt Studio)
+  - Per-user directories under `TLDW_USER_DATA_PATH` (or defaults) with strict path sanitization and safe file handling
+- Key Components:
+  - `chatbook_service.py` (export/import/preview, job state, signed URLs)
+  - `chatbook_validators.py` (file/ZIP/manifest validation), `quota_manager.py` (tier limits)
+  - Optional `ps_job_adapter.py` for Prompt Studio JobManager integration
+  - `chatbook_models.py` (content types, job models)
+- Configuration:
+  - `CHATBOOKS_JOBS_BACKEND` (`core` default) or legacy `TLDW_USE_PROMPT_STUDIO_QUEUE`
+  - `TLDW_USER_DATA_PATH`, `CHATBOOKS_SIGNED_URLS`, `CHATBOOKS_SIGNING_SECRET`, `CHATBOOKS_URL_TTL_SECONDS`, `CHATBOOKS_ENFORCE_EXPIRY`
+  - Core jobs tuning: `JOBS_POLL_INTERVAL_SECONDS`, `JOBS_LEASE_SECONDS`, `JOBS_LEASE_RENEW_SECONDS`, `JOBS_LEASE_RENEW_JITTER_SECONDS`
+- Concurrency & Performance:
+  - BackgroundTasks for async paths; worker-based job execution; quotas prevent abuse
+- Error Handling & Security:
+  - Path traversal prevention, symlink rejection, per-file size caps, unsafe extension filters
+  - Ownership checks on download; avoid logging secrets; structured errors
+- Tests (examples):
+  - tldw_Server_API/tests/Chatbooks/test_chatbooks_export_sync.py
+  - tldw_Server_API/tests/Chatbooks/test_chatbooks_signed_urls.py
+  - tldw_Server_API/tests/Chatbooks/test_chatbook_service.py
+  - tldw_Server_API/tests/integration/test_chatbook_integration.py
+
+## 3. Developer-Related/Relevant Information for Contributors
+
 - Path: `tldw_Server_API/app/core/Chatbooks`
 - Purpose: Backup, export, import, and preview of user content (conversations, notes, characters, world books, dictionaries, media, embeddings, generated docs) as a portable “chatbook” ZIP with a JSON manifest. Supports multi-user isolation, quotas, and async job processing.

+- Purpose: Unified web search and aggregation across multiple providers with optional LLM-powered subquery generation, relevance scoring, and final-answer synthesis.
+- Providers: Google CSE, DuckDuckGo, Brave (AI/web), Kagi, Searx, Tavily. Bing is present in legacy code but not exposed as a supported engine in the public schema.
+- Pipeline (optional stages):
+  - Subquery generation via LLM to broaden coverage.
+  - Provider search, normalization, and result shaping.
+  - Optional user review/selection step.
+  - Relevance evaluation via LLM and article scraping for evidence.
+  - Aggregation into a concise final answer with citations and a confidence estimate.
+- Cancellation-aware: Aggregate stage observes client disconnect and aborts in-flight work.
+- Security and egress: Outbound requests respect centralized egress/SSRF policy; provider calls use browser-like headers.
+- Inputs/Outputs:
+  - Request model: `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:14` (engine, query, options, aggregation flags)
+  - Raw response: `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:62`
+  - Aggregate response + final answer: `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:52`, `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:67`
+- Related Endpoint:
+  - `POST /api/v1/research/websearch` — `tldw_Server_API/app/api/v1/endpoints/research.py:279`
+
+Notes
+- The API endpoint today delegates to the Web_Scraping implementation for providers and orchestration. This module hosts the parallel pipeline (and helpers) as part of an ongoing consolidation effort.
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Provider adapters, aggregation pipeline.
-- Key Classes/Functions: Entry points and extension points.
-- Dependencies: Internal modules and external search APIs/SDKs.
-- Data Models & DB: Any persisted caches or indices.
-- Configuration: Env vars, API keys, config keys.
-- Concurrency & Performance: Batching, caching, rate limits.
-- Error Handling: Retries, backoff, partial failures.
-- Security: AuthNZ and safe usage of provider credentials.
+- Architecture & Flow
+  - Phase 1 (Generate + Search): `generate_and_search` builds sub-queries (optional), executes provider calls, and normalizes results.
+    - Web_Scraping orchestration: `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:154`
+  - Phase 2 (Analyze + Aggregate): `analyze_and_aggregate` runs relevance analysis, optional user review, and LLM aggregation.
+    - Web_Scraping aggregation: `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:254`
+  - Final answer shape: text, evidence (snippets), chunk summaries, confidence.
+- Provider Adapters (Web_Scraping)
+  - Google CSE: `search_web_google` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1542`, `parse_google_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1713`
+  - Brave: `search_web_brave` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1199`, `parse_brave_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1269`
+  - DuckDuckGo: `search_web_duckduckgo` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1339`, `parse_duckduckgo_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1459`
+  - Kagi: `search_web_kagi` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1820`, `parse_kagi_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1861`
+  - Searx: `search_web_searx` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:1925`, `parse_searx_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:2021`
+  - Tavily: `search_web_tavily` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:2085`, `parse_tavily_results` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:2134`
+  - Article scraping used during relevance/summary: `scrape_article` `tldw_Server_API/app/core/Web_Scraping/Article_Extractor_Lib.py:335`
+  - UA Profiles: `tldw_Server_API/app/core/Web_Scraping/ua_profiles.py:2`, browser-like headers helper `_websearch_browser_headers` `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:34`
+- Endpoint Integration
+  - Router: `tldw_Server_API/app/api/v1/endpoints/research.py:279` (offloads phase 1 to a thread pool and observes client disconnect during phase 2).
+  - Thread pool configuration: `tldw_Server_API/app/api/v1/endpoints/research.py:321`
+- LLM Usage
+  - Subquery generation and relevance analysis leverage the unified chat stack and summarization:
+    - Chat orchestrator entry: `tldw_Server_API/app/core/Chat/chat_orchestrator.py:77`
+    - General summarization: `tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:312`
+- Security
+  - Egress/SSRF policy: `evaluate_url_policy` `tldw_Server_API/app/core/Security/egress.py:146` is enforced before external calls in providers and scrapers.
+- Configuration
+  - Provider keys and knobs are read from `search_engines` in `config.txt` (via config loader). Common keys include:
+    - Google: `google_search_api_key`, `google_search_engine_id`, `google_search_api_url`, `limit_google_search_to_country`
+    - Brave: `brave_search_api_key`, `brave_search_ai_api_key`, `search_engine_country_code_brave`
+    - Searx: `searx_search_api_url`
+    - Tavily: `tavily_search_api_key`
+  - Headers/profile selection via `ua_profiles` helpers.
+- Error Handling
+  - Provider adapters return structured dicts with `processing_error` when normalization fails; endpoint traps exceptions and returns 500 with error detail.
+  - Aggregate stage guards against malformed LLM outputs; returns a safe fallback when summarization is unavailable.

-
+- Folder Structure
+  - This module (`core/WebSearch`) contains the parallel pipeline and helpers. The API endpoint currently delegates to `core/Web_Scraping/WebSearch_APIs.py`, which also holds provider adapters, UA profiles, and the article scraper.
+- Adding/Updating a Provider
+  - Implement `search_web_` and a matching `parse__results` that appends standardized items into `web_search_results_dict`.
+  - Enforce egress policy at the start of any network call using `evaluate_url_policy`.
+  - Use `_websearch_browser_headers` for realistic headers where appropriate.
+  - Update supported engines if the provider becomes publicly exposed: `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:9`–`tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:19`.
+- Endpoint/Auth
+  - The endpoint requires an authenticated user (dependency `get_request_user`) and mounts under `/api/v1/research` in the main app.
+- Tests (good starting points)
+  - Endpoint happy-path and aggregate path: `tldw_Server_API/tests/WebSearch/integration/test_websearch_endpoint.py:1`
+  - Engine-specific routing (tavily, searx, kagi): `tldw_Server_API/tests/WebSearch/integration/test_websearch_engines_endpoint.py:1`
+  - Non-blocking generate offload behavior: `tldw_Server_API/tests/WebSearch/unit/test_nonblocking_generate.py:1`
+  - Parsers unit tests (Google/Brave/DDG/Kagi): `tldw_Server_API/tests/WebSearch/unit/test_parsers.py:1`
+  - Searx/Tavily parsers: `tldw_Server_API/tests/WebSearch/unit/test_parsers_extended.py:1`
+  - Egress guard (security): `tldw_Server_API/tests/Security/test_websearch_egress_guard.py:1`
+  - Browser-like header shape: `tldw_Server_API/tests/Web_Scraping/test_websearch_headers.py:1`
+- Local Dev Tips
+  - Start the app and call `POST /api/v1/research/websearch` with a small `result_count` and `aggregate=false` to validate provider wiring before testing aggregation.
+  - Configure provider keys in `Config_Files/config.txt` (and/or `.env`) prior to live calls.
+  - For aggregation, set `relevance_analysis_llm` and `final_answer_llm` to a configured provider name from the chat stack.
+- Pitfalls & Gotchas
+  - Provider quotas and per-request limits (e.g., Google CSE `num`, Brave AI token) can constrain `result_count`.
+  - Some providers (Searx/Tavily) require self-hosted instance URL or API key.
+  - Endpoint-level behavior assumes network access; tests may mock providers or accept 500 in offline environments.
+  - Bing is deprecated in the public schema; avoid re-exposing without a clear migration/test plan.
+- Roadmap/TODOs
+  - Consolidate Web_Scraping provider adapters into this module and ensure a single pipeline implementation.
+  - Expand structured relevance outputs to reduce regex-based parsing.
+  - Optional caching layer for provider results to reduce egress and cost.

+  - Searches via RAG (`POST /api/v1/rag/search` and `GET /api/v1/rag/simple` if exposed).

 ### Settings and Auth
 - Allow any `serverUrl` (http/https); validate via a health check.
+- Health check path: `GET /api/v1/health` (optional lightweight: `/healthz`, readiness: `/readyz`). Treat non-200 as not ready.
 - Modes: Single‑User uses `X-API-KEY: `. Multi‑User uses `Authorization: Bearer `.
 - Manage access token in memory; persist refresh token only when necessary.
 - Auto‑refresh on 401 with single‑flight queue; one retry per request.
 - Never log secrets; redact sensitive fields in errors.
 
+- MV3 token lifecycle: persist refresh token in `chrome.storage.local` to survive service worker suspension/restart; keep access token in memory (or `chrome.storage.session`). On background start, attempt auto‑refresh when a refresh token exists; use single‑flight refresh queue on 401.
+
 ### Network Proxy (Background/Service Worker)
 - All API calls originate from background; UI/content never handles tokens directly.
 - Optional host permissions per configured origin at runtime; least privilege.
-- SSE support: set `Accept: text/event-stream`, parse events, keep‑alive handling, `AbortController` cancellation.
+- SSE support: set `Accept: text/event-stream`, parse events (including handling `[DONE]` sentinel), keep‑alive handling, `AbortController` cancellation.
 - Timeouts with exponential backoff (jitter). Offline queue for small writes.
+- Propagate an `X-Request-ID` header per request for correlation and idempotent retries.
 
 ### API Path Hygiene
 - Match the server’s OpenAPI exactly, including trailing slashes where specified, to avoid redirects and CORS quirks.

+  - Search: `GET /api/v1/notes/search/` (trailing slash required)

+- Chat SSE shape: Expect OpenAI-style chunks with "delta" objects, then "[DONE]". Parse lines like `data: {"choices":[{"delta":{"role":"assistant","content":"..."}}]}` and terminate on `[DONE]`.
+- RAG streaming is NDJSON (not SSE). Treat each line as a complete JSON object; do not expect `[DONE]`. Endpoints: `POST /api/v1/rag/search/stream` (stream), `GET /api/v1/rag/simple` (simple retrieval).
+- Health signals: `GET /api/v1/health` returns status "ok" (200) or "degraded" (206). Treat any non-200 as not ready during setup. Use `/readyz` (readiness) and `/healthz` (liveness) for lightweight probes.

 ### Chat
 - Support `stream: true|false`, model selection, and OpenAI‑compatible request fields.
 - Pause/cancel active streams; display partial tokens.
 - Error UX: connection lost, server errors, token expiration.
+- SSE streaming must detect and handle the `[DONE]` sentinel to terminate cleanly; keep the service worker alive during streams (e.g., via a long‑lived Port from the side panel).

 ## Acceptance Criteria (Key)
 - Path Hygiene: All requests hit exact API paths defined by OpenAPI; no 307s observed in logs.
 - Security: Tokens never appear in UI or console logs; content scripts lack access to tokens.
-- SSE: Streaming responses parsed without memory leaks; cancel stops network within ~200ms.
+- SSE: Streaming responses parsed without memory leaks; recognizes `[DONE]`; cancel stops network within ~200ms.
 - Retry/Refresh: 401 triggers single‑flight refresh; queued requests replay once; exponential backoff with jitter for network errors.
 - Permissions: Optional host permissions requested only for user‑configured origin; revocation handled gracefully.
 - Media: Ingest current tab URL; show progress and final status; errors actionable.
 - STT/TTS: Supported formats accepted; errors surfaced with clear messages.
+- 429 Handling: Honors `Retry-After` on rate limits; UI presents retry timing.
+- Streaming Memory: No unbounded memory growth during 5‑minute continuous streams; remains within budget.
 
 ## Dependencies

-## Open Questions
-- Confirm canonical API key header name: proceeding with `X-API-KEY`. Any alternate accepted?
-- Is `/api/v1/llm/models` present alongside `/api/v1/llm/providers`? If both, which is authoritative for selection?
-- Do Notes/Prompts endpoints require trailing slash on search routes in current server build?
-- Preferred handling for self‑signed HTTPS during development?
+## Resolved Decisions
+- Canonical API key header: `X-API-KEY` (single‑user). Multi‑user uses `Authorization: Bearer `.
+- Model discovery: Prefer `GET /api/v1/llm/providers` (authoritative provider→models); `GET /api/v1/llm/models` available as aggregate.
+- Trailing slashes: See “Trailing Slash Rules (Notes/Prompts)” above (notes search and collections require trailing slash; prompts base/search do not).
+- Dev HTTPS: Prefer HTTP on localhost; for HTTPS, trust a local CA or enable Chrome’s localhost invalid‑cert exception; ensure server CORS allows the extension origin.
+
+## Developer Validation Checklist
+- Connectivity & Auth
+  - Set server URL and verify `GET /api/v1/health` succeeds.
+  - Single‑user: requests with `X-API-KEY` succeed; Multi‑user: login/refresh/logout succeeds and access token auto‑refreshes after service worker suspend/resume.
+- Path Hygiene
+  - All calls are 2xx without redirects (no 307); Notes/Prompts follow trailing‑slash rules.
+- Chat
+  - Non‑stream and SSE stream both work; `[DONE]` handled; cancel closes network <200ms; models list loads from `/api/v1/llm/providers`.
+- RAG
+  - `POST /api/v1/rag/search` returns results; `GET /api/v1/rag/simple` works; `POST /api/v1/rag/search/stream` NDJSON parsed correctly.
+- Media
+  - Current tab URL ingest works; progress logs displayed; failures surface actionable errors; job polling (if job id present) functions with backoff.
+- Notes & Prompts
+  - Notes CRUD + `GET /api/v1/notes/search/` (with slash) work; Prompts base/search work; keywords endpoints reachable.
+- Audio
+  - STT accepts <= 25 MB and returns transcript; TTS synthesizes and plays; voices catalog fetched.
+- Reliability
+  - 429 responses respect `Retry-After`; 5xx/network use exponential backoff with jitter; offline queue for small writes visible.
+- Permissions
+  - Only the configured server origin is granted host permission; revocation handled gracefully.
+- CORS/HTTPS
+  - Extension origin allowed by server; dev HTTP works; dev HTTPS usable with trusted cert or localhost exception.
+- Metrics/Headers
+  - `X-Request-ID` sent on requests and echoed; `traceparent` present in responses.
+- Performance
+  - Background steady memory < 50 MB; streaming memory stable over 5 minutes; first chat token < 1.5s on LAN.
 
 ## Glossary
 - SSE: Server‑Sent Events; streaming over HTTP.
 - MV3: Chrome Manifest V3.
 - Background Proxy: Service worker owning all network I/O and auth.

 # Search_and_Research
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Unified research workflows and search orchestration.
-- Capabilities: Provider search, aggregation, enrichment, reranking.
-- Inputs/Outputs: Queries; aggregated, ranked results.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Umbrella for research-oriented capabilities: general web search with optional LLM aggregation and paper/preprint discovery across providers (arXiv, Semantic Scholar, PubMed/PMC, OSF, Zenodo, etc.).
+- Capabilities:
+  - Web search pipeline (multi-provider) with subquery generation, relevance scoring, article scraping, and final-answer synthesis. See WebSearch README for provider details.
+  - Paper search endpoints under `/api/v1/paper-search/*` for domain-specific sources (arXiv, Semantic Scholar, BioRxiv, PubMed/PMC, OSF, Zenodo, and others), with pagination and normalization.
+  - Optional ingestion of paper content into Media DB for later RAG and downstream analysis.
+- Inputs/Outputs:
+  - Web search request/response models: `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:14`, `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:62`, `tldw_Server_API/app/api/v1/schemas/websearch_schemas.py:67`.
+  - Paper search request/response models: `tldw_Server_API/app/api/v1/schemas/research_schemas.py:20`, `tldw_Server_API/app/api/v1/schemas/research_schemas.py:30`, `tldw_Server_API/app/api/v1/schemas/research_schemas.py:84`, `tldw_Server_API/app/api/v1/schemas/research_schemas.py:112`.
+- Related Endpoints:
+  - Web search: `POST /api/v1/research/websearch` — `tldw_Server_API/app/api/v1/endpoints/research.py:279`.
+  - Paper search (preferred): `GET /api/v1/paper-search/arxiv` — `tldw_Server_API/app/api/v1/endpoints/paper_search.py:24` and subsequent handlers; see file for additional providers.
+  - Deprecated research shims: `GET /api/v1/research/arxiv-search` and `GET /api/v1/research/semantic-scholar-search` — `tldw_Server_API/app/api/v1/endpoints/research.py:59`, `tldw_Server_API/app/api/v1/endpoints/research.py:210`.
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Research pipeline stages and handoffs.
-- Key Classes/Functions: Entry points and extension points.
-- Dependencies: Internal modules; external web/search APIs.
-- Data Models & DB: Storage and caches via `DB_Management`.
-- Configuration: Env vars, feature flags, API keys.
-- Concurrency & Performance: Batching, caching, rate limiting.
-- Error Handling: Retries, partial failures, backoff.
-- Security: Respect provider ToS and safety.
+- Architecture & Data Flow
+  - Web search flow: generate_and_search (subqueries + provider calls) → analyze_and_aggregate (relevance LLM + scraping + final answer). Implementation currently lives in `core/Web_Scraping/WebSearch_APIs.py` and is delegated by the `research` endpoint.
+  - Paper search flow: per-provider handlers under `paper_search.py` call into `core/Third_Party/*` modules, normalize to Pydantic schemas, and support pagination.
+  - Optional ingestion path: arXiv example uses `MediaDatabase.add_media_with_keywords` to persist parsed/summarized content — `tldw_Server_API/app/api/v1/endpoints/research.py:131`.
+- Key Functions/Modules
+  - Web search endpoint glue: `tldw_Server_API/app/api/v1/endpoints/research.py:279` delegates phase 1 to a thread pool and phase 2 to async aggregation with disconnect-aware cancellation.
+  - Web search orchestration and providers: `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:154` (generate), `tldw_Server_API/app/core/Web_Scraping/WebSearch_APIs.py:254` (aggregate), plus `search_web_*`/`parse_*` for each provider.
+  - Paper providers (selection): `tldw_Server_API/app/core/Third_Party/Arxiv.py`, `Semantic_Scholar.py`, `BioRxiv.py`, `PubMed.py`, `PMC_OA.py`, `PMC_OAI.py`, etc.
+- Dependencies
+  - LLM stack for subquery generation and relevance/aggregation: `tldw_Server_API/app/core/Chat/chat_orchestrator.py:77`, `tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:312`.
+  - Article scraping for evidence: `tldw_Server_API/app/core/Web_Scraping/Article_Extractor_Lib.py:335`.
+  - DB persistence: `tldw_Server_API/app/core/DB_Management/Media_DB_v2.py` via `MediaDatabase`.
+- Configuration
+  - Provider API keys and URLs are loaded from `Config_Files/config.txt` (section `search_engines` and third-party sections). For web search engines, see the WebSearch README.
+  - Per-provider throttling/limits vary by upstream API; tests favor mocking.
+- Concurrency & Performance
+  - Web search provider calls are offloaded to a `ThreadPoolExecutor` to keep the event loop responsive — `tldw_Server_API/app/api/v1/endpoints/research.py:321`.
+  - Aggregate stage is async and supports cancellation if the client disconnects.
+- Security
+  - All outbound HTTP calls are expected to honor centralized egress/SSRF policy via `evaluate_url_policy` — `tldw_Server_API/app/core/Security/egress.py:146`. This is explicitly enforced in the web search providers and the article scraper.
+- Error Handling
+  - Endpoint returns structured HTTP errors on upstream failures and safe fallbacks in aggregation when LLM output is malformed or unavailable.
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: Adding providers or enrichment steps.
-- Coding Patterns: DI, logging, metrics.
-- Tests: Where tests live; fixtures and mocking.
-- Local Dev Tips: Example queries and debug.
-- Pitfalls & Gotchas: Schema drift, quotas.
-- Roadmap/TODOs: Planned enhancements.
+- Folder Structure
+  - `core/Search_and_Research`: umbrella docs (this README). Active implementations are split across `core/Web_Scraping` (web search orchestration/providers) and `core/Third_Party` (paper sources), with API glue in `app/api/v1/endpoints/research.py` and `paper_search.py`.
+- Adding a Paper Provider
+  - Implement provider-specific fetch/normalize logic in `core/Third_Party/.py`.
+  - Add an endpoint to `paper_search.py` returning the appropriate Pydantic response model; mirror query params used by provider.
+  - Ensure egress policy checks precede any network calls; prefer `httpx` clients with `trust_env=False`.
+- Tests
+  - Web search endpoint and aggregation: `tldw_Server_API/tests/WebSearch/integration/test_websearch_endpoint.py:1`.
+  - Engine routing and provider stubs: `tldw_Server_API/tests/WebSearch/integration/test_websearch_engines_endpoint.py:1`.
+  - Paper search external integrations: `tldw_Server_API/tests/PaperSearch/integration/test_paper_search_external.py:1` and provider-specific tests under the same folder (e.g., `.../test_arxiv_external.py`, `.../test_zenodo_external.py`).
+  - Egress guard: `tldw_Server_API/tests/Security/test_websearch_egress_guard.py:1`.
+- Local Dev Tips
+  - Start with small page sizes and low `result_count` to avoid quotas. Configure provider keys/URLs in `config.txt` and `.env`.
+  - Use the deprecated research shims only for backward compatibility; prefer `/paper-search/*`.
+- Pitfalls & Gotchas
+  - Provider quotas, pagination semantics, and schema drift can vary (e.g., Semantic Scholar `next` offset). Keep parsers defensive and tests mocked.
+  - Web search “Bing” is present in legacy code but is not part of the supported engine set exposed by the public schema.
+- Roadmap/TODOs
+  - Consolidate web search orchestration into `core/WebSearch` (currently delegated to `core/Web_Scraping`).
+  - Add caching for frequently repeated paper queries and search results.
+  - Expand standardized evidence capture for aggregated answers.

+## Stream logs (WebSocket)
+WS `/api/v1/sandbox/runs/{id}/stream`
+- Optional query: `from_seq=` (1.1 resume)
+- When signed URLs are enabled, include `token` and `exp` query params.
+Frames:
+- `{ "type": "event", "event": "start" }`
+- `{ "type": "stdout"|"stderr", "encoding": "utf8"|"base64", "data": "...", "seq": 123 }`
+- `{ "type": "heartbeat", "seq": 124 }`
+- `{ "type": "truncated", "reason": "log_cap", "seq": 125 }`
+- `{ "type": "event", "event": "end", "data": {"exit_code": 0}, "seq": 126 }`
+- Interactivity (1.1): client→server stdin frames `{ "type": "stdin", "encoding": "utf8"|"base64", "data": "..." }`
+
+## Artifacts
+- List: GET `/api/v1/sandbox/runs/{id}/artifacts`
+- Download: GET `/api/v1/sandbox/runs/{id}/artifacts/{path}`
+  - Single Range supported: `Range: bytes=start-end`; multi-range returns 416.
+
+## Idempotency conflicts
+409, example:
+```
+{
+  "error": {
+    "code": "idempotency_conflict",
+    "message": "Idempotency-Key replay with different body",
+    "details": { "prior_id": "", "key": "", "prior_created_at": "" }
+  }
+}
+```
+
+## Health
+- Authenticated: GET `/api/v1/sandbox/health` (includes store timings and Redis ping)
+- Public: GET `/api/v1/sandbox/health/public` (no auth)
+
+## Notes
+- Spec versions are validated against server config. Default: `["1.0","1.1"]`.
+- Interactivity requires runtime and policy support; fields are ignored otherwise.
+- `log_stream_url` may be unsigned; prefer Authorization headers if signed URLs are disabled.

-# Browser Extension
+# Browser Extension — PRD (Compat v0.1)
 
+Status: Active
+Owner: Server/API + WebUI
+Updated: 2025-11-03
 
+Purpose
+- This PRD defines the product and technical contract for the tldw_server browser extension as it integrates with the current backend. It is not a greenfield extension spec; it codifies compatibility requirements, endpoints, security posture, and UX flows so the existing extension can be brought to parity with the server.
 
-### Link Dump:
-https://github.com/josStorer/chatGPTBox
-https://github.com/navedmerchant/MyDeviceAI
-https://github.com/Aletech-Solutions/XandAI-Extension
+Summary
+- Provide a light, secure capture-and-interact surface that talks to tldw_server: chat, RAG search, reading capture, media ingest (URL/process), and audio (STT/TTS). Aligns with server AuthNZ (single-user API key and multi-user JWT) and uses a background proxy for all network I/O.
+
+Goals
+- Backend compatibility with current server APIs (Chat, RAG, Media, Reading, Audio, LLM models/providers).
+- Minimal-permissions extension with background-only header injection.
+- Reliable streaming (SSE) and WS STT handling in MV3 background.
+- Basic UX: popup/sidepanel chat, quick capture, context-menu actions.
+
+Non-Goals (initial)
+- Headless JS rendering for JS-heavy sites; authenticated/session scraping.
+- Public/social sharing; multi-tenant cloud distribution.
+- Complex workflow editing inside the extension.
+
+Personas
+- Researcher/Analyst: search + summarize, capture links for later reading.
+- Power User: model selection, quick ingest, audio utilities.
+- Casual User: quick save + simple chat.
+
+Success Metrics
+- Connection success rate to configured server; auth error rate.
+- Chat stream completion rate and cancel latency (<200ms average).
+- RAG query success; ingest success vs. validation failures.
+- STT/TTS success rates; WS connection stability.

+  - GET /api/v1/llm/providers
+- Chats (resource model; optional v1 scope)
+  - /api/v1/chats/* (create/list/get/update/delete sessions; messages CRUD; complete/stream where available)
+
+AuthNZ & Headers
+- Modes: single_user (X-API-KEY) and multi_user (Authorization: Bearer )
+- Background-only header injection; never expose tokens to content scripts.
+- WS STT: token passed as query param (?token=...) as supported by server.
+
+Architecture
+- MV3 background service worker owns all network I/O (fetch/SSE) and WS STT.
+- Content scripts do not call server directly; they message background.
+- Streaming: background uses fetch + ReadableStream to parse SSE; forwards frames to UI via ports.
+- Drift guard: On startup, background optionally fetches /openapi.json and logs missing required paths (advisory).
+
+Permissions & CSP (least privilege)
+- Chromium: use optional_host_permissions for the configured server origin; do not request broad host globs by default.
+- Firefox: minimize host wildcards; no webRequest/webRequestBlocking unless absolutely required.
+- Remove unused permissions (e.g., declarativeNetRequest) to ease store review.
+
+Security & Privacy
+- Token storage policy: access tokens in background memory or session storage; refresh tokens optionally persisted in local storage; never store or expose tokens in content scripts; never log tokens.
+- No telemetry; local-first.
+- Sanitize and re-set auth headers in background before each fetch.
+
+SSE & WS Behavior
+- Headers: Accept: text/event-stream; Cache-Control: no-cache; Connection: keep-alive.
+- Idle timeout: default ≥45s; reset on any event/data; abort on idle.
+- Cancel: AbortController used to cancel long streams quickly.
+- WS STT: binary frames; handle connection errors; fall back to file-based STT when blocked.
+
+UX Flows (high level)
+- Popup/Sidepanel
+  - Tabs: Chat, RAG, Reading (Save Current Tab), Ingest (Process-only), Audio (STT/TTS)
+  - Model/provider picker (optional)
+- Context Menu
+  - “Send to tldw_server” → POST /api/v1/media/add { url }
+  - “Process page (no save)” → POST /api/v1/media/process-*
+- Options Page
+  - Server URL, auth mode, credentials; permissions grant to server origin
+  - Stream idle timeout; connect tester; show OpenAPI drift warnings
+
+Error Handling & Observability
+- 401 refresh (multi-user) single-flight retry; show actionable messages on 429/402 with backoff.
+- Surface friendly errors for size/type validation and unsupported URLs.
+- Optional dev toggle for stream debug logging.
+
+Testing Strategy
+- Unit: SSE parser, header injection, request builders, URL→process-* classifier.
+- Integration: chat stream with cancel; rag search; reading save; media add/process; STT/TTS.
+- Manual: service worker suspend/resume, optional host permission grant/revoke.
+
+Rollout & Compatibility
+- Chrome MV3 first; Firefox MV2 compatibility tracked; Safari after.
+- Require server exposing endpoints listed above; use drift guard to warn on mismatches.
+
+Risks & Mitigations
+- MV3 worker suspend: hold streams via long-lived ports; use idle timeout resets.
+- Anti-scraping limits: rely on server throttling and robots compliance.
+- Content variability: prefer URL submission to server; avoid raw DOM capture.
+
+References
+- Server APIs: see tldw_Server_API/README.md and Docs/Product/Content_Collections_PRD.md
+- Extension implementation plan lives in the separate extension repo’s Extension-Plan-1.md

+# Resource Governance PRD (v1)
+
+## Summary
+
+Multiple independent rate limiters and quota mechanisms exist across the codebase with overlapping logic and inconsistent semantics (burst behavior, refunding, test bypass, metrics, persistence). This PRD proposes a unified ResourceGovernor capable of governing per-entity resource limits for requests, tokens, streams, jobs, and minutes using a shared interface and pluggable backends (in-memory and Redis) with consistent test-mode behavior, metrics tags, and refund semantics.
+
+## Problem & Symptoms
+
+- Fragmented rate limiting/quota implementations per feature lead to duplication, drift, and inconsistent outcomes:
+  - Chat token bucket + per-conversation limits: `tldw_Server_API/app/core/Chat/rate_limiter.py:1`
+  - MCP in-memory/Redis limiter + category limiters: `tldw_Server_API/app/core/MCP_unified/auth/rate_limiter.py:1`
+  - Embeddings sliding window limiter: `tldw_Server_API/app/core/Embeddings/rate_limiter.py:1`
+  - Global SlowAPI limiter: `tldw_Server_API/app/api/v1/API_Deps/rate_limiting.py:1`
+  - Audio quotas (daily minutes, concurrent streams/jobs): `tldw_Server_API/app/core/Usage/audio_quota.py:1`
+- Additional duplications not originally listed but present:
+  - AuthNZ DB/Redis limiter: `tldw_Server_API/app/core/AuthNZ/rate_limiter.py:1`
+  - Evaluations per-user limiter and usage ledger: `tldw_Server_API/app/core/Evaluations/user_rate_limiter.py:1`
+  - Character Chat limiter (Redis + memory): `tldw_Server_API/app/core/Character_Chat/character_rate_limiter.py:1`
+  - Web scraping rate limiters: `tldw_Server_API/app/core/Web_Scraping/enhanced_web_scraping.py:125`
+  - Embeddings server token-bucket decorator: `tldw_Server_API/app/core/Embeddings/Embeddings_Server/Embeddings_Create.py:1030`
+
+Symptoms:
+- Inconsistent burst multipliers and windows; different interpretations of “per minute”.
+- Hard-to-reason interactions between limiters (e.g., SlowAPI + per-module meters).
+- Divergent test bypass logic (varied env flags, ad-hoc behavior).
+- Inconsistent metrics (names, labels, presence) and poor cross-feature visibility.
+- Code complexity and maintenance overhead; bugs from drift and duplicated env parsing.
+
+## Goals
+
+- One unified ResourceGovernor module to manage “per-entity resource limits” across categories:
+  - Categories: `requests`, `tokens`, `streams`, `jobs`, `minutes`.
+- Pluggable backends: in-memory (single-instance) and Redis (multi-instance), chosen by configuration.
+- Consistent API supporting reserve/commit/refund and query, with atomic composite reservations across categories when possible.
+- First-class test-mode behavior (deterministic bypass or fixed limits) without per-feature custom parsing.
+- Standardized metrics and tracing for allow/deny/wait/refund with consistent label sets.
+- Compatibility shims for existing modules; incremental migration plan.
+
+Non-goals (v1):
+- Redesigning pricing/billing or tier models.
+- Replacing durable ledgers where they make sense (e.g., daily minutes table for audio).
+- Removing SlowAPI entirely; it can remain as an ingress façade backed by the governor.
+
+## Personas & Entities
+
+- Persona: API user (API key/JWT user id), service client (MCP client id), conversation id (Chat), IP address (ingress fallback), system services.
+- Entity key format: `scope:value` where scope ∈ {`user`, `api_key`, `client`, `ip`, `conversation`, `tenant`, `service`}.
+- Effective entity: per endpoint determines which entity keys apply. Examples:
+  - Chat: `user:{id}`, optionally `conversation:{id}`; tokens reserved under `tokens` and request under `requests`.
+  - Audio stream: `user:{id}` governing `streams` semaphore and `minutes` ledger.
+  - MCP: `client:{id}` or `user:{id}` with `requests` in categories `ingestion` or `read` via tags.
+
+## Functional Requirements
+
+- Core interface:
+  - check(spec) → decision: Returns allow/deny with retry_after and metadata.
+  - reserve(spec, op_id) → handle: Reserves resources atomically across categories (best-effort rollback on partial failures). `op_id` is an idempotency key.
+  - commit(handle, actual_usage, op_id) → None: Finalizes reservation and records usage (e.g., minutes consumed, tokens used). Idempotent per `op_id`.
+  - refund(handle or delta, op_id) → None: Returns unused capacity (e.g., estimated vs actual tokens; failure paths). Idempotent per `op_id`.
+  - renew(handle, ttl_s) → None: Renews concurrency leases (streams/jobs) heartbeat before TTL expiry.
+  - release(handle) → None: Explicitly releases concurrency leases (streams/jobs) when finished.
+  - peek(query) → usage: Returns current usage and remaining headroom per category/entity.
+  - reset(entity/category) → None: Administrative reset.
+
+- Categories & semantics:
+  - `requests`: token-bucket or sliding-window RPM/RPS limits; burst configured.
+  - `tokens`: token-bucket for budgeted tokens per window (e.g., per minute).
+  - `streams`: semaphore-like concurrency limit (bounded integer counter) with lease TTL/heartbeat.
+  - `jobs`: semaphore-like concurrency limit with queue-aware labeling; optional per-queue limits.
+  - `minutes`: durable, per-day (UTC) ledger; supports add on commit and check before reserve.
+
+- Default algorithms and formulas:
+  - `requests`: token-bucket by default. Capacity `C = burst * rate * window`; refill at `rate` per second. Sliding-window may be selected per policy for very small-window accuracy.
+  - `tokens`: token-bucket by default. Units are model tokens when available; otherwise generic estimated tokens as a stand-in.
+  - `streams/jobs`: bounded counters with per-lease TTL; requires `renew` heartbeat to keep leases alive.
+  - `minutes`: durable daily cap; see Minutes Ledger Semantics.
+
+## Time Sources
+
+- All time calculations for windows, TTLs, and expirations use monotonic clocks via a `TimeSource` abstraction to avoid wall-clock jumps.
+- `ResourceGovernor` accepts a `time_source` parameter (defaults to a monotonic provider). Tests inject a fake time source for deterministic control.
+
+- Composite reservation: Reserve in deterministic order to minimize deadlock; on failure, release prior reserves.
+
+- Test mode:
+  - Prefer a single project-wide flag `TLDW_TEST_MODE=true`; `RG_TEST_BYPASS` may override governor behavior for tests.
+  - In test mode: no burst (`burst=1.0`), deterministic timing, optional fixed limits via `RG_TEST_*` envs.
+  - Zero reliance on request headers for bypass.
+
+- Metrics & tracing:
+  - Metrics emitted on every decision: allow/deny, reserve/commit/refund, with labels: `category`, `scope`, `backend`, `result`, `reason`, `endpoint`, `service`, `policy_id`. Entity is excluded by default; optionally include a hashed entity label when `RG_METRICS_ENTITY_LABEL=true`.
+  - Gauges for concurrency (`streams_active`, `jobs_active`); counters for denials and refunds.
+  - Optional exemplars and trace IDs if tracing enabled.
+
+- Configuration:
+  - Policy source of truth:
+    - Production precedence (high→low): AuthNZ DB policy store → env overrides → YAML policy file → defaults.
+    - Development/Test precedence (high→low): env overrides → YAML policy file → defaults.
+  - Shared env var prefix `RG_*` (examples below) with legacy alias mapping for backward compatibility.
+
+## Non-Functional Requirements
+
+- Correctness under concurrency; atomicity across categories best-effort with rollback.
+- Performance suitable for hot paths; constant-time checks and minimal allocations.
+- Minimal lock contention; per-entity locks, monotonic time usage.
+- Clean resource cleanup (idle entry GC) and Redis TTLs to prevent leaks.
+- Backwards compatible rollout with shims and metrics parity.
+
+## Architecture & API
+
+- Module location: `tldw_Server_API/app/core/Resource_Governance/`
+  - `ResourceGovernor` (facade) — processes rules, composes category managers, handles composite reservations.
+- Backends:
+  - `InMemoryBackend` — dicts + locks; token buckets, sliding windows, semaphores.
+  - `RedisBackend` — ZSET sliding windows, token buckets, and robust semaphore leases with TTL.
+  - Categories:
+    - `RequestsLimiter` (token bucket or sliding window per rule).
+    - `TokensLimiter` (token bucket with refund support).
+  - `ConcurrencyLimiter` (streams/jobs using counters with TTL + heartbeat).
+    - `MinutesLedger` (durable DB-backed; reuses audio minutes schema for v1 with abstract interface).
+  - Types:
+    - `EntityKey(scope: str, value: str)`
+    - `Category(str)`; `LimitSpec` (rate, window, burst, max_concurrent, daily_cap, etc.)
+    - `ReservationHandle(id, items, metadata, ttl, expires_at)` with implicit expiry tracking.
+    - `TimeSource` interface providing monotonic `now()`; default binds to `time.monotonic()`; tests can inject a fake time source.
+
+- Proposed Python signature (simplified):
+
+```python
+@dataclass
+class RGRequest:
+    entity: EntityKey
+    # Units: requests → 1 per HTTP call; tokens → model tokens (preferred) or estimated generic tokens.
+    categories: Dict[str, Dict[str, int]]  # e.g., {"requests": {"units": 1}, "tokens": {"units": 1200}}
+    tags: Dict[str, str] = field(default_factory=dict)  # endpoint, service, policy_id, etc.
+
+@dataclass
+class RGDecision:
+    allowed: bool
+    retry_after: int | None

+    #       "tokens":   {"allowed": bool, "limit": int, "used": int, "remaining": int, "retry_after": int | None},
+    #       ...
+    #   }
+    # }
+    details: Dict[str, Any]
+
+class ResourceGovernor:
+    async def check(self, req: RGRequest) -> RGDecision: ...
+    async def reserve(self, req: RGRequest, op_id: str | None = None) -> tuple[RGDecision, str]: ...  # returns (decision, handle_id)
+    async def commit(self, handle_id: str, actuals: Dict[str, int] | None = None, op_id: str | None = None) -> None: ...
+    async def refund(self, handle_id: str, deltas: Dict[str, int] | None = None, op_id: str | None = None) -> None: ...

+    async def release(self, handle_id: str) -> None: ...  # explicit release for concurrency leases
+    async def peek(self, entity: EntityKey, categories: list[str]) -> Dict[str, Any]: ...
+    async def query(self, entity: EntityKey, category: str) -> Dict[str, Any]: ...  # normalized diagnostics view
+    async def reset(self, entity: EntityKey, category: str | None = None) -> None: ...
+```
+
+- Atomicity strategy:
+  - For Redis: use Lua scripts or MULTI/EXEC to reserve multiple categories; on partial failure, rollback prior reservations.
+  - For memory: acquire category locks in stable order; on failure, release acquired reservations.
+
+- Redis concurrency lease design:
+  - Use a ZSET per entity/category (e.g., `rg:lease:::`) containing `member=lease_id`, `score=expiry_ts`.
+  - Acquire via Lua: purge expired (ZREMRANGEBYSCORE), check `ZCARD < limit`, `ZADD` new lease with expiry. Return `lease_id` as handle.
+  - Renew via `ZADD` with updated expiry for `lease_id`. Release via `ZREM` on `lease_id`.
+  - Periodic GC sweeps ensure eventual cleanup; avoid pure INCR/DECR to eliminate race hazards.
+
+- Refund semantics:
+  - Chat: reserve estimated tokens; on completion, commit actual tokens used and refund the difference.
+  - Failures: refund all prior reservations; log reason and emit refund metrics.
+  - Time-bounded reservations: auto-expire stale handles; periodic cleanup task.
+  - Safety: cap refunds by prior reservation per category to avoid negative usage; validate `actuals <= reserved` unless policy explicitly enables overage handling.
+
+- Handle lifecycle:
+  - `ReservationHandle` includes `expires_at` and `op_id`. Background sweeper reclaims expired handles across backends.
+  - All state transitions (reserve, commit, refund, renew, release, expire) include a `reason` for audit and metrics.
+
+- Policy composition semantics (strictest wins):
+  - For each category, compute remaining headroom per applicable scope (global, tenant, user, conversation, etc.). Effective headroom is the minimum across scopes (strictest constraint).
+  - Allow if the effective headroom ≥ requested units; otherwise deny for that category.
+  - Compute per-scope `retry_after`; the category’s `retry_after` is the maximum across denying scopes. Overall `retry_after` is the maximum across denied categories.
+
+## Configuration
+
+- New standardized env vars (legacy aliases maintained via mapping during migration):
+  - `RG_BACKEND`: `memory` | `redis`
+  - `RG_REDIS_URL`: Redis URL
+  - `RG_TEST_BYPASS`: `true|false` (defaults to honoring `TEST_MODE`)
+  - `RG_REDIS_FAIL_MODE`: `fail_closed` | `fail_open` | `fallback_memory` (defaults to `fail_closed`). Controls behavior on Redis outages.
+    - Default `fail_closed` is recommended for write paths and global-coordination categories; use `fallback_memory` only for non-critical categories where local over-admission is acceptable.
+  - `RG_CLIENT_IP_HEADER`: Header to trust for client IP when behind trusted proxies (e.g., `X-Forwarded-For`, `CF-Connecting-IP`).
+  - `RG_TRUSTED_PROXIES`: Comma-separated CIDRs for trusted reverse proxies; when unset, IP scope uses the direct remote address only.
+  - `RG_METRICS_ENTITY_LABEL`: `true|false` (default `false`). If true, include hashed entity label in metrics; otherwise exclude to avoid high cardinality.
+  - `RG_POLICY_STORE`: `file` | `db` (default `file`). In production, prefer `db` and use AuthNZ DB as SoT; in dev, `file` + env overrides.
+  - `RG_POLICY_DB_CACHE_TTL_SEC`: TTL for DB policy cache (default 10s) when `RG_POLICY_STORE=db`.
+  - Category defaults (fallbacks applied per module if unspecified):
+    - `RG_REQUESTS_RPM_DEFAULT`, `RG_REQUESTS_BURST`
+    - `RG_TOKENS_PER_MIN_DEFAULT`, `RG_TOKENS_BURST`
+    - `RG_STREAMS_MAX_CONCURRENT_DEFAULT`, `RG_STREAMS_TTL_SEC`
+    - `RG_JOBS_MAX_CONCURRENT_DEFAULT`
+    - `RG_MINUTES_DAILY_CAP_DEFAULT` (still enforced via durable ledger)
+
+- Back-compat mapping examples:
+  - `MCP_RATE_LIMIT_*` → RequestsLimiter rules for service `mcp`.
+  - Chat `TEST_CHAT_*` → test-mode overrides for chat-specific rules.
+  - Audio quotas envs (`AUDIO_*`) remain for `minutes` and concurrency defaults.
+
+- Test mode semantics:
+  - Prefer a single project-wide flag `TLDW_TEST_MODE=true`.
+  - `RG_TEST_BYPASS` overrides only the governor’s behavior; precedence: `RG_TEST_BYPASS` if set, else `TLDW_TEST_MODE`.
+  - In test mode, defaults: no burst (`burst=1.0`), deterministic timing, and optional fixed limits via `RG_TEST_*` envs.
+
+## Ingress Scoping & IP Derivation
+
+- Derive the effective entity for ingress using auth scopes when available (`user`, `api_key`, `client`).
+- For `ip` scope behind proxies, require explicit configuration:
+  - Only trust `RG_CLIENT_IP_HEADER` when the immediate peer IP is within `RG_TRUSTED_PROXIES`.
+  - Otherwise, use the direct remote address.
+  - If both auth and IP are available, prefer auth scopes for rate limits; use IP as fallback.
+
+## Policy DSL & Route Mapping
+
+- Central policy file in YAML (hot-reloadable) declares limits per category and scope with identifiers:
+
+```yaml
+policies:
+  chat.default:
+    requests: { rpm: 120, burst: 2.0 }
+    tokens:   { per_min: 60000, burst: 1.5 }
+    scopes: [global, user, conversation]
+    fail_mode: fail_closed
+  mcp.ingestion:
+    requests: { rpm: 60, burst: 1.0 }
+    scopes: [global, client]
+    fail_mode: fallback_memory
+```
+
+- Routes attach `policy_id` via FastAPI route tags or decorators. An ASGI middleware reads the tag and consults the governor. SlowAPI decorators remain as config carriers only.
+- Policy reload: file watcher or periodic TTL check; swap policies atomically. Invalid updates are rejected with clear logs.
+- Per-category overrides: policy `fail_mode` may override `RG_REDIS_FAIL_MODE` for that policy/category.
+- Stub location: `tldw_Server_API/Config_Files/resource_governor_policies.yaml` provides default examples and hot-reload settings.
+- Source of Truth in production: policies stored in AuthNZ DB (e.g., `rg_policies`) with JSON payloads and `updated_at` timestamps.
+  - Cache layer with TTL and/or change feed; hot-reload applies atomically across workers.
+  - Env vars remain as development overrides; DB wins in production when present.
+
+## Integration Plan (Phased Migration)
+
+Phase 0 — Ship ResourceGovernor (no integrations yet)
+- Implement `ResourceGovernor` module with memory + Redis backends and category primitives.
+- Add metrics emission via existing registry (labels: category, scope, backend, result, policy_id).
+- Provide test-mode handling in one place.
+
+Phase 1 — MCP
+- Replace `tldw_Server_API/app/core/MCP_unified/auth/rate_limiter.py` internals with a thin façade over ResourceGovernor categories `requests` with tags `category=ingestion|read`.
+- Preserve public API (`get_rate_limiter`, `RateLimitExceeded`) to avoid breaking imports.
+
+Phase 2 — Chat
+- Replace `ConversationRateLimiter` with `requests` + `tokens` categories.
+- Keep per-conversation policy by composing the entity key `conversation:{id}` in addition to `user:{id}`.
+- Maintain `initialize_rate_limiter` signature; under the hood, use ResourceGovernor.
+
+Phase 3 — SlowAPI façade
+- Configure `API_Deps/rate_limiting.py` to use `limiter.key_func` for ingress scoping (`ip`/`user`) and delegate allow/deny to ResourceGovernor `requests` category before handlers.
+- Keep decorator usage (`@limiter.limit(...)`) as a config carrier only. Map decorator strings to RG policies using route tags (e.g., `tags={"policy_id": "chat.default"}`) and an ASGI middleware that consults the governor. No in-SlowAPI counters.
+- Policy resolution reads from the YAML policy file (see Policy DSL & Route Mapping) with hot-reload support.
+
+Phase 4 — Embeddings
+- Replace `UserRateLimiter` with ResourceGovernor `requests` limits; for large-cost ops, optionally also a `tokens` category if desired.
+- Remove ad-hoc env parsing; map legacy envs to `RG_*`.
+
+Phase 5 — Audio quotas
+- Keep durable minutes ledger DB exactly as-is but implement limits via `minutes` category interface.
+- Replace in-process concurrent `streams`/`jobs` counters with `ConcurrencyLimiter` (with Redis TTL heartbeat support).
+
+Phase 6 — Evaluations, AuthNZ, Character Chat, Web Scraping, Embeddings Server
+- Gradually replace each with governor-backed categories; preserve public APIs during deprecation window.
+
+Phase 7 — Cleanup & removal
+- Delete/retire old limiter implementations once their consumers are migrated.
+- Keep minimal façade shims that import ResourceGovernor and raise deprecation warnings.
+
+## Deletions / Consolidation Targets
+
+- Replace and then delete (or shim):
+  - `tldw_Server_API/app/core/Chat/rate_limiter.py`
+  - `tldw_Server_API/app/core/MCP_unified/auth/rate_limiter.py`
+  - `tldw_Server_API/app/core/Embeddings/rate_limiter.py`
+  - `tldw_Server_API/app/api/v1/API_Deps/rate_limiting.py` (convert to façade)
+  - `tldw_Server_API/app/core/Usage/audio_quota.py` (concurrency + check plumbing via governor; keep minutes DB ledger implementation)
+  - Plus: `AuthNZ` limiter, `Evaluations` limiter, `Character_Chat` limiter, `Web_Scraping` limiters, and Embeddings server decorator limiter
+
+- Remove custom per-file env parsing once policy merges into shared config.
+
+## Metrics & Observability
+
+- Counters:
+  - `rg_decisions_total{category,scope,backend,result,policy_id}` (entity excluded by default; optionally include hashed entity when `RG_METRICS_ENTITY_LABEL=true`).
+  - `rg_refunds_total{category,scope,reason,policy_id}`
+  - `rg_denials_total{category,scope,reason,policy_id}`
+  - `rg_shadow_decision_mismatch_total{route,policy_id,legacy,rg}` (shadow-mode only; counts divergences between legacy limiter and RG decisions)
+- Gauges:
+  - `rg_concurrency_active{category,scope,policy_id}` (for streams/jobs)
+- Histograms:
+  - `rg_wait_seconds{category,scope,policy_id}` when wait/retry paths are used
+- Logs:
+  - Structured with category, decision, retry_after, reason, policy_id; include `handle_id` and `op_id` where applicable.
+  - Never log raw `api_key`; mask or include only an HMAC/hashed form for diagnostics. Do not emit PII in logs.
+
+### HTTP Headers
+
+- For HTTP endpoints governed by the `requests` category, emit standard headers for compatibility during migration:
+  - `Retry-After: ` on 429 responses based on the overall decision’s `retry_after`.
+  - `X-RateLimit-Limit: ` reflects the strictest applicable limit for the `requests` category.
+  - `X-RateLimit-Remaining: ` reflects the remaining headroom under that strictest scope after the decision.
+  - `X-RateLimit-Reset: ` or `` until reset, aligned to the governing window.
+- For concurrency denials (e.g., `streams`), return `429` with `Retry-After` set from the category decision; do not emit misleading `X-RateLimit-*` unless the route is also governed by `requests`.
+- Maintain SlowAPI-compatible behavior on migrated routes to avoid client regressions.
+
+## Security & Privacy
+
+- Redaction:
+  - Treat API keys, user identifiers, and IPs as sensitive; never log raw values. Use hashed/HMAC forms with a server-secret salt for correlation when necessary.
+  - Metrics must not include high-cardinality PII. Do not emit raw entity values; optional hashed entity is gated behind `RG_METRICS_ENTITY_LABEL=true`.
+- Tenant scope:
+  - Include `tenant:{id}` as a first-class scope from the outset, even if initial policies are no-op. This avoids retrofit costs and enables future isolation. The tenant id may be derived from a trusted header or JWT claim.
+- Data minimization:
+  - Expose only aggregated counters/gauges/histograms. Keep detailed per-entity diagnostics in sampled logs with redaction.
+
+## Minutes Ledger Semantics
+
+- Daily accounting is based on UTC. When a usage period overlaps midnight UTC, split minutes across the two UTC days on `commit`.
+- Retroactive commits are disallowed by default; optionally allow with an explicit `occurred_at` timestamp and policy gates. If allowed, minutes accrue to the UTC day of `occurred_at`.
+- Rounding: track internal usage at sub-minute resolution; charge per policy rounding rules (e.g., ceil to nearest minute on commit) consistently.
+
+### Generic Daily Ledger (v1.1)
+
+- Plan: Introduce a generic `DailyLedger` abstraction to extend beyond `minutes` (e.g., `tokens_per_day`).
+- Interface (concept): `add(entity, category, units, occurred_at_utc)`, `remaining(entity, category, day)`, `peek(entity, category)`, `reset(...)`.
+- Storage: reuse existing DB with a generalized schema (`day_utc`, `entity`, `category`, `units`), plus indexes; migrate audio minutes to this ledger.
+- Semantics: UTC-based partitioning; consistent rounding per policy; idempotent commits via `op_id`.
+- Rollout: shadow existing minutes ledger first; then cut over with migration script. Target version: v1.1.
+
+## Database Schemas
+
+### Policy Store (AuthNZ DB)
+
+- PostgreSQL
+
+```sql
+CREATE TABLE IF NOT EXISTS rg_policies (
+  id TEXT PRIMARY KEY,                -- policy_id, e.g., 'chat.default'
+  payload JSONB NOT NULL,            -- full policy object
+  version INTEGER NOT NULL DEFAULT 1,
+  updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+
+-- Optional index for updated_at for fast latest reads
+CREATE INDEX IF NOT EXISTS idx_rg_policies_updated_at ON rg_policies (updated_at DESC);
+```
+
+- SQLite
+
+```sql
+CREATE TABLE IF NOT EXISTS rg_policies (
+  id TEXT PRIMARY KEY,
+  payload TEXT NOT NULL,             -- JSON-encoded
+  version INTEGER NOT NULL DEFAULT 1,
+  updated_at TEXT NOT NULL           -- ISO8601 UTC
+);
+
+CREATE INDEX IF NOT EXISTS idx_rg_policies_updated_at ON rg_policies (updated_at);
+```
+
+Notes:
+- The server constructs a merged snapshot from all rows keyed by `id` with the latest `updated_at`.
+- In production, the AuthNZ subsystem owns read/write APIs for this table.
+
+### Generic Daily Ledger (v1.1)
+
+- PostgreSQL
+
+```sql
+CREATE TABLE IF NOT EXISTS resource_daily_ledger (
+  id BIGSERIAL PRIMARY KEY,
+  day_utc DATE NOT NULL,
+  entity_scope TEXT NOT NULL,        -- e.g., 'user', 'client', 'tenant'
+  entity_value TEXT NOT NULL,        -- identifier for the scope (PII handling at app layer)
+  category TEXT NOT NULL,            -- e.g., 'minutes', 'tokens_per_day'
+  units BIGINT NOT NULL CHECK (units >= 0),
+  op_id TEXT NOT NULL,               -- idempotency key
+  occurred_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+  created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+
+CREATE UNIQUE INDEX IF NOT EXISTS uq_ledger_op ON resource_daily_ledger (day_utc, entity_scope, entity_value, category, op_id);
+CREATE INDEX IF NOT EXISTS idx_ledger_lookup ON resource_daily_ledger (entity_scope, entity_value, category, day_utc);
+```
+
+- SQLite
+
+```sql
+CREATE TABLE IF NOT EXISTS resource_daily_ledger (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  day_utc TEXT NOT NULL,             -- 'YYYY-MM-DD'
+  entity_scope TEXT NOT NULL,
+  entity_value TEXT NOT NULL,
+  category TEXT NOT NULL,
+  units INTEGER NOT NULL,
+  op_id TEXT NOT NULL,
+  occurred_at TEXT NOT NULL,         -- ISO8601 UTC
+  created_at TEXT NOT NULL           -- ISO8601 UTC
+);
+
+CREATE UNIQUE INDEX IF NOT EXISTS uq_ledger_op ON resource_daily_ledger (day_utc, entity_scope, entity_value, category, op_id);
+CREATE INDEX IF NOT EXISTS idx_ledger_lookup ON resource_daily_ledger (entity_scope, entity_value, category, day_utc);
+```
+
+Notes:
+- App layer enforces `units >= 0` and splits usage across UTC day boundaries at commit time.
+- Over-aggregation (e.g., totals table) can be added later if needed for performance.
+
+### Cross-Category Budgets (Modeling)
+
+- Future concept: define a `cost_unit` conversion map in policy (e.g., 1 token = 0.001 CU, 1 request = 1 CU) to track budget consumption uniformly across categories without changing enforcement semantics.
+- Implement later (post v1.1) to avoid scope creep; used for analytics and optional budget caps.
+
+## Test Strategy
+
+- Unit tests (memory backend):
+  - Token bucket and sliding window correctness for `requests` and `tokens`.
+  - Concurrency limiter (acquire/release/heartbeat/TTL expiry).
+  - Minutes ledger adapter (mock DB) correctness across day boundaries (UTC).
+  - Composite reservation rollback and idempotent refunding.
+  - Test-mode bypass and deterministic burst behavior.
+  - Mockable `TimeSource` injection to drive time-dependent behavior deterministically.
+
+- Unit tests (Redis backend):
+  - Lua script operations for sliding window and token bucket; atomic composite reservations.
+  - Redis TTL behavior and cleanup.
+
+- Integration tests:
+  - Replace MCP limiter via façade; verify 429 and retry headers remain correct.
+  - Chat path: estimated token reservation and refund with actual usage from provider responses.
+  - Audio streaming: enforce `streams` concurrency and daily `minutes` cap, including heartbeat.
+  - SlowAPI façade routes: verify ingress keys map to governor and rate limits apply consistently.
+  - Failover modes: verify `fail_closed`, `fail_open`, and `fallback_memory` behaviors under Redis outage simulation.
+
+- Chaos tests:
+  - Induce Redis outages and network partitions; assert behavior per `RG_REDIS_FAIL_MODE`. Validate metrics emit `backend=fallback` and decisions match expectations.
+  - Simulate wall-clock drift vs monotonic time; ensure window math uses monotonic source and remains stable.
+
+- Property-based tests:
+  - Verify token-bucket vs sliding-window equivalence under selected parameter sets (e.g., large windows, steady inter-arrival, low burst). Use Hypothesis to generate arrival patterns; assert admitted counts converge within tolerance.
+
+- Concurrency stress tests:
+  - High-contention acquire/release with lease TTL expiry, overlapping `renew` and `release`. Validate no leaks, no double-release, and correct ZSET membership behavior under churn.
+
+- Shadow-mode validation:
+  - Run legacy limiter and RG in parallel; emit delta metric when decisions differ; fail test on sustained mismatches. Cover requests/tokens and concurrency categories.
+
+- Coverage targets: ≥ 80% for the new module with both backends; keep existing suites green.
+
+## Rollout & Compatibility
+
+- Feature flags: `RG_ENABLED=true|false` (default true in dev; off-by-default can be considered for safety in production).
+- Legacy env compatibility layer logs a warning once per process on use.
+- Shadow mode (optional): evaluate decisions with RG and existing limiter in parallel, emit delta metrics, and compare before cutover.
+
+### Per-Module Feature Flags
+
+- In addition to the global toggle, each integration can be enabled/disabled independently during migration:
+  - `RG_ENABLE_MCP`
+  - `RG_ENABLE_CHAT`
+  - `RG_ENABLE_SLOWAPI`
+  - `RG_ENABLE_AUDIO`
+  - `RG_ENABLE_EMBEDDINGS`
+  - `RG_ENABLE_EVALUATIONS`
+  - `RG_ENABLE_AUTHNZ`
+  - `RG_ENABLE_CHARACTER_CHAT`
+  - `RG_ENABLE_WEB_SCRAPING`
+  - `RG_ENABLE_EMBEDDINGS_SERVER`
+- Convention: any unset module flag inherits from `RG_ENABLED`.
+
+### Compat Map (Legacy → RG)
+
+- General rules:
+  - When both legacy and RG envs are set, RG envs take precedence.
+  - On process start, detect legacy envs in use and log a once-per-process deprecation warning with the mapped `RG_*` equivalent and a removal target version.
+  - Where applicable, legacy decorator parameters (e.g., SlowAPI) are ignored once RG integration is enabled; their presence is logged as informational with the resolved `policy_id`.
+
+- MCP (examples):
+  - `MCP_RATE_LIMIT_RPM` → policy `mcp.ingestion.requests.rpm`
+  - `MCP_RATE_LIMIT_BURST` → policy `mcp.ingestion.requests.burst`
+  - `MCP_REDIS_URL` → `RG_REDIS_URL` (alias)
+  - `MCP_RATE_LIMIT_TEST_BYPASS` → `RG_TEST_BYPASS`
+
+- Chat (examples):
+  - `CHAT_GLOBAL_RPM` → policy `chat.default.requests.rpm` (scope `global`)
+  - `CHAT_PER_USER_RPM` → policy `chat.default.requests.rpm` (scope `user`)
+  - `CHAT_PER_CONVERSATION_RPM` → policy `chat.default.requests.rpm` (scope `conversation`)
+  - `CHAT_PER_USER_TOKENS_PER_MINUTE` → policy `chat.default.tokens.per_min`
+  - `TEST_CHAT_*` → `RG_TEST_*` or policy test overrides
+
+- SlowAPI (examples):
+  - `SLOWAPI_GLOBAL_RPM` → policy `ingress.default.requests.rpm`
+  - `SLOWAPI_GLOBAL_BURST` → policy `ingress.default.requests.burst`
+  - Decorator strings remain as config carriers; actual enforcement is via RG when `RG_ENABLE_SLOWAPI=true`.
+
+- Audio (examples):
+  - `AUDIO_DAILY_MINUTES_CAP` → policy `audio.default.minutes.daily_cap`
+  - `AUDIO_MAX_CONCURRENT_STREAMS` → policy `audio.default.streams.max_concurrent`
+  - `AUDIO_STREAM_TTL_SEC` → `RG_STREAMS_TTL_SEC`
+
+- Embeddings (examples):
+  - `EMBEDDINGS_RPM` → policy `embeddings.default.requests.rpm`
+  - `EMBEDDINGS_BURST` → policy `embeddings.default.requests.burst`
+
+- Evaluations/AuthNZ/Character Chat/Web Scraping (examples):
+  - `EVALS_RPM` → policy `evals.default.requests.rpm`
+  - `AUTHNZ_RPM` → policy `authnz.default.requests.rpm`
+  - `CHARACTER_CHAT_RPM` → policy `character_chat.default.requests.rpm`
+  - `WEB_SCRAPING_RPM` → policy `web_scraping.default.requests.rpm`
+
+### SlowAPI ASGI Middleware
+
+- Provide an ASGI middleware adapter (e.g., `RGSlowAPIMiddleware`) that:
+  - Extracts `policy_id` from route tags/decorators.
+  - Derives the effective entity (auth scopes preferred; IP fallback with trusted-proxy rules).
+  - Calls RG `check/reserve` before handler; on deny, returns 429 with headers; on allow, sets `X-RateLimit-*` headers and proceeds.
+  - On completion, performs `commit/refund` as applicable; handles streaming by renewing/releasing leases.
+  - When `RG_ENABLE_SLOWAPI=false`, middleware is disabled and legacy SlowAPI behavior remains.
+
+## Risks & Mitigations
+
+- Partial failures across categories → perform deterministic order, rollback on failure, log anomalies.
+- Redis outages → auto-fallback to in-memory with warning; emit `backend=fallback` metric tag.
+- Behavior drift from legacy implementations → shadow mode comparisons and golden tests.
+- Test flakiness with time windows → use monotonic time and deterministic burst in `TLDW_TEST_MODE`.
+- Metrics cardinality → exclude `entity` from metric labels by default; optionally include hashed entity via `RG_METRICS_ENTITY_LABEL`; sample per-entity logs for diagnostics.
+- Concurrency lease management → provide explicit `renew` and `release`; use per-lease IDs and TTLs; GC expired leases.
+- IP scoping behind proxies → require `RG_TRUSTED_PROXIES` and `RG_CLIENT_IP_HEADER` to trust forwarded addresses; prefer auth scopes over IP when available.
+- Policy composition ambiguity → define strictest-wins semantics (min headroom across applicable scopes) per category; compute `retry_after` as max across denying scopes and categories.
+- Fallback-to-memory over-admission → make behavior configurable via `RG_REDIS_FAIL_MODE` (default `fail_closed`); emit metrics on failover; consider per-category overrides.
+- Idempotency on retries → require `op_id` for reserve/commit/refund; operations are idempotent per `op_id` and handle.
+- Minutes ledger edge cases → split usage across UTC day boundaries; define rounding rules; restrict retroactive commits or require `occurred_at`.
+- Env flag drift → standardize on `TLDW_TEST_MODE`; `RG_TEST_BYPASS` only overrides governor behavior with documented precedence.
+
+## Open Questions
+
+- Minutes generalization: planned for v1.1 via a generic DailyLedger (see Minutes Ledger Semantics). For v1, reuse audio minutes ledger only.
+- Cross-category budgets: do we want a global “cost units” budget that maps tokens/requests into a unified spend?
+- Tier/source of truth: adopt AuthNZ DB as the policy SoT in production with cache + hot-reload; keep env+YAML as dev overrides.
+- Multi-tenant isolation: do we introduce `tenant:{id}` as a first-class scope now?
+
+
+## Acceptance Criteria
+
+- New `ResourceGovernor` module with memory + Redis backends and the specified API.
+- MCP, Chat, and SlowAPI ingress paths migrated to the unified governor with no regression in public API or tests.
+- Audio streams concurrency and minutes cap enforced via the governor, with durable minutes persisted as before.
+- Embeddings limiter replaced; Evaluations/AuthNZ/Character Chat/Web Scraping scheduled for follow-on.
+- Consistent test-mode bypass and refund semantics demonstrated in tests.
+- Metrics emitted with the standardized label set; basic dashboards updated.
+- Compat map documented and implemented with deprecation warnings for legacy envs.
+- Per-module feature flags available and honored during phased rollout.
+- Roadmap captured: v1.1 generic DailyLedger plan documented; cross-category budget model noted for future.
+
+## Appendix — Mapping table (initial examples)
+
+- Chat
+  - Before: `ConversationRateLimiter` with `global_rpm`, `per_user_rpm`, `per_conversation_rpm`, `per_user_tokens_per_minute`.
+  - After: `requests` for global/user/conversation via policy rules; `tokens` per user with burst; refund on completion.
+
+- MCP
+  - Before: in-memory/Redis with `ingestion` and `read` categories.
+  - After: `requests` with tag `category=ingestion|read`; same RPMs, Redis kept via backend.
+
+- Audio
+  - Before: DB-backed daily minutes + in-process/Redis counters for streams/jobs.
+  - After: `minutes` via durable ledger adapter; `streams`/`jobs` via `ConcurrencyLimiter` with TTL heartbeat.
+
+- SlowAPI
+  - Before: global limiter with key_func sentinel for TEST_MODE.
+  - After: façade that derives entity key and delegates to `requests` governor, retaining decorators for route config.
+
+- Embeddings
+  - Before: sliding window per user.
+  - After: `requests` for per-user RPM with burst support via governor rules.
+
+- Evaluations/AuthNZ/Character Chat/Web Scraping
+  - Before: bespoke.
+  - After: move to governor with appropriate categories; keep per-feature knobs as policy inputs.

+# Stream Abstraction — PRD
+
+- Status: Draft
+- Last Updated: 2025-11-03
+- Authors: Codex (coding agent)
+- Stakeholders: API (Chat/Embeddings), Audio, MCP, WebUI, Docs
+
+---
+
+## 1. Overview
+
+### 1.1 Summary
+Unify streaming across Server‑Sent Events (SSE) and WebSockets under a single abstraction so features share consistent framing, normalization, heartbeat, and completion semantics. Introduce an `AsyncStream` interface with transport‑specific implementations (`SSEStream`, `WebSocketStream`) that route all provider data through a single normalization path and standardized DONE/error frames (with canonical error codes).
+
+### 1.2 Motivation & Background
+- Symptom: repeated, inconsistent SSE/WebSocket line formatting, normalization, and completion handling across endpoints and modules.
+- Duplicates/examples today:
+  - Endpoint‑local SSE line builder: `tldw_Server_API/app/api/v1/endpoints/character_chat_sessions.py:1..120` (`_extract_sse_data_lines`).
+  - Central SSE helpers already exist: `tldw_Server_API/app/core/LLM_Calls/sse.py`.
+  - Provider line normalization scattered: `tldw_Server_API/app/core/LLM_Calls/streaming.py`.
+  - SSE emitters in embeddings orchestrator: `tldw_Server_API/app/api/v1/endpoints/embeddings_v5_production_enhanced.py:3500+`.
+  - WebSockets in Audio and MCP with similar framing/heartbeat/error behavior:
+    - `tldw_Server_API/app/core/Ingestion_Media_Processing/Audio/Audio_Streaming_Unified.py`.
+    - `tldw_Server_API/app/core/MCP_unified/server.py`.
+
+Unifying principle: All outputs are streams — just different transports.
+
+### 1.3 Goals
+1. Single, composable interface for streaming outputs across transports.
+2. One normalization path for provider outputs (OpenAI‑compatible SSE chunks; consistent WS frames).
+3. Standard DONE and error semantics (code + message); no duplicate `[DONE]` emission.
+4. Consistent heartbeat/keepalive policy for SSE and WS.
+5. Reduce code duplication and simplify endpoint logic.
+6. Provide clear backpressure behavior for SSE (bounded queue) and consistent WS close code mapping.
+
+### 1.4 Non‑Goals
+- Changing wire payload shapes for domain data (e.g., audio partials, MCP JSON‑RPC responses). The abstraction standardizes framing/lifecycle, not domain schemas.
+- Introducing a new message bus or queueing layer.
+
+---
+
+## 2. User Stories
+
+| Story | Persona | Description |
+| --- | --- | --- |
+| US1 | API consumer (Chat) | “When I stream chat completions, I want consistent SSE framing and a single `[DONE]` sentinel across providers.” |
+| US2 | WebUI engineer | “I want identical heartbeat and error semantics whether a feature uses SSE or WebSockets.” |
+| US3 | Backend dev | “I want to implement streaming without re‑writing `[DONE]` and error handling for each endpoint.” |
+| US4 | Maintainer | “I want to delete endpoint‑local SSE helpers and rely on a central abstraction with tests.” |
+
+---
+
+## 3. Requirements
+
+### 3.1 Functional Requirements
+1. Provide `AsyncStream` interface with at least:
+   - `send_event(event: str, data: Any | None = None)` — named event emission (maps to `event:` + `data:` for SSE; `{type: "event", event, data}` for WS where used).
+   - `send_json(payload: dict)` — structured data (maps to `data:` for SSE; JSON frame over WS).
+   - `done()` — emit end‑of‑stream (SSE: `data: [DONE]`; WS: `{type: "done"}`) and close if appropriate.
+   - `error(code: str, message: str, *, data: dict | None = None)` — emit structured error frame and close when transport requires.
+2. Implement `SSEStream` for FastAPI `StreamingResponse` generators:
+   - Internals: async queue‑backed emitter; `iter_sse()` async generator yields lines to the response.
+   - Use `sse.ensure_sse_line`, `sse.sse_data`, `sse.sse_done`, `sse.normalize_provider_line`.
+   - Suppress provider `[DONE]`; ensure exactly one terminal `[DONE]` from our layer.
+   - Optional `heartbeat_interval_s` emitting `":"` comment lines (default); support `data` heartbeat mode.
+   - Provide `send_raw_sse_line(line: str)` as SSE‑specific helper for hot paths; not part of `AsyncStream`.
+   - Bounded queue (`queue_maxsize`) with documented backpressure policy.
+3. Implement `WebSocketStream` over Starlette/FastAPI WS:
+   - Lifecycle frames: `{type: "error", code, message, data?}`; `{type: "done"}`; `{type: "ping"}`/`{type: "pong"}`.
+   - Optional pings via `{type: "ping"}` at `heartbeat_interval_s`; reply to `{type: "pong"}`.
+   - Map application error codes to WS close reasons consistently.
+   - Event frames `{type: "event", event, data}` are optional; domain payloads remain unchanged for Audio/MCP.
+4. Centralize provider stream normalization:
+   - Reuse `app/core/LLM_Calls/streaming.py` for `requests` and `httpx` SSE iteration.
+   - Route all chat provider streams through this module before transport emission.
+5. Backward compatible payloads:
+   - Chat/OpenAI SSE: preserve `choices[].delta.content` shapes.
+   - Embeddings orchestrator: keep `event: summary` structure; move emission to `SSEStream.send_event("summary", payload)`.
+   - Audio and MCP WS: keep domain JSON schemas; only standardize lifecycle (error/done/heartbeat).
+6. Observability:
+   - Consistent log messages for start/stop/error with `stream_id`/`connection_id`.
+   - Metrics (labels: include `transport`, `kind` where applicable, and optional stream `labels` from constructors like `{`"component"`:"chat"}`):
+     - `sse_enqueue_to_yield_ms` (histogram, ms): time from call to enqueue to iterator yield/write.
+     - `ws_send_latency_ms` (histogram, ms): time to complete `send_json` writes; `kind` in {event,json,error,done,ping}.
+     - `sse_queue_high_watermark` (gauge): max queue depth observed.
+     - `ws_pings_total` (counter): ping frames sent.
+     - `ws_ping_failures_total` (counter): ping send errors.
+     - `ws_idle_timeouts_total` (counter): WS connections closed due to idle timeout.
+   - Drop counters are emitted only when drop‑oldest mode is enabled.
+
+### 3.2 Non‑Functional Requirements
+- No measurable latency regression vs current code paths.
+- Memory footprint stable under long‑lived streams.
+- High availability under intermittent network conditions (graceful error frames).
+
+### 3.3 Canonical Error Codes
+- `quota_exceeded` — request exceeds quotas or limits
+- `idle_timeout` — idle timeout reached
+- `transport_error` — network/stream transport failure
+- `provider_error` — upstream LLM/provider signaled an error
+- `validation_error` — bad client input
+- `internal_error` — server-side error
+
+### 3.4 WebSocket Close Code Mapping
+- 1000 — normal closure (e.g., `{type: "done"}`)
+- 1001 — going away/idle timeout
+- 1008 — policy violation (e.g., auth/rate-limit failures)
+- 1011 — internal server error
+
+Usage guidance:
+- `quota_exceeded`: send `{type:"error", code:"quota_exceeded", ...}` then close with 1008.
+- `idle_timeout`: close with 1001 (a preceding error frame is optional and generally omitted for simplicity).
+- `internal_error`: send `{type:"error", code:"internal_error", ...}` then close with 1011.
+- `transport_error`: often cannot send an error reliably; close with 1011 if possible.
+
+---
+
+## 4. UX & API Design
+
+### 4.1 Transport Semantics
+- SSE
+  - Media type: `text/event-stream`.
+  - Heartbeat: `":"\n\n"` comments at configurable interval (default 10s). Configurable mode to send `data: {"heartbeat": true}` if needed.
+  - Termination: single `data: [DONE]\n\n`.
+  - Errors: `data: {"error": {"code", "message", "data"}}`.
+    - Closure policy: configurable. Default closes stream on error. Per-call override available on `SSEStream.error(..., close=bool)`.
+- WebSocket
+  - Heartbeat: `{type: "ping"}` at configurable interval (default 10s) with optional client `{type: "pong"}`.
+  - Termination: `{type: "done"}` followed by close (default 1000; configurable).
+  - Errors: `{type: "error", code, message, data}` then close as needed (mapping in 3.4).
+    - Transitional compatibility (Audio/WebUI): include `error_type` alias mirroring `code` during rollout.
+
+### 4.2 Developer Interface (Illustrative)
+```python
+class AsyncStream(Protocol):
+    async def send_event(self, event: str, data: Any | None = None) -> None: ...
+    async def send_json(self, payload: dict) -> None: ...
+    async def done(self) -> None: ...
+    async def error(self, code: str, message: str, *, data: dict | None = None) -> None: ...
+
+class SSEStream(AsyncStream):

+
+### 4.4 SSE Endpoint Example
+
+```python
+from fastapi import APIRouter
+from fastapi.responses import StreamingResponse
+from tldw_Server_API.app.core.Streaming.streams import SSEStream
+
+router = APIRouter()
+
+@router.get("/chat/stream")
+async def chat_stream():
+    stream = SSEStream(
+        heartbeat_interval_s=10,
+        heartbeat_mode="data",
+        labels={"component": "chat", "endpoint": "chat_stream"},
+    )
+
+    async def generator():
+        # In a real endpoint, start a background task to feed the stream
+        # await stream.send_json({...}) / await stream.send_event("summary", {...}) / await stream.done()
+        async for line in stream.iter_sse():
+            yield line
+
+    headers = {
+        "Cache-Control": "no-cache",
+        "X-Accel-Buffering": "no",
+    }
+    return StreamingResponse(generator(), media_type="text/event-stream", headers=headers)
+```
+
+### 4.3 Backward Compatibility
+- Existing SSE clients continue to receive identical `data:` frames (including OpenAI style deltas and a final `[DONE]`).
+- Existing WS clients continue to receive domain JSON; only lifecycle frames become standardized (`error`, `done`, `ping`).
+
+---
+
+## 5. Technical Approach
+
+1. Abstraction
+   - New module: `tldw_Server_API/app/core/Streaming/streams.py`, containing `AsyncStream`, `SSEStream`, `WebSocketStream`.
+   - Import `sse.ensure_sse_line`, `sse.normalize_provider_line`, `sse.sse_data`, `sse.sse_done`.
+2. Normalization
+   - Keep a single normalization path in `LLM_Calls/streaming.py` for iterating provider SSE and suppressing provider `[DONE]`.
+   - Endpoints compose:
+     - Option A (hot path): `for line in iter_sse_lines_requests(...): await sse_stream.send_raw_sse_line(line)`.
+     - Option B (structured): build OpenAI‑compatible deltas and `await stream.send_json(openai_delta)`.
+3. Heartbeats
+   - Shared config: `STREAM_HEARTBEAT_INTERVAL_S` (default 10), `STREAM_IDLE_TIMEOUT_S`, `STREAM_MAX_DURATION_S` — overridable per endpoint.
+   - SSE: comment line `":"` (or `data: {"heartbeat": true}` when configured).
+   - WS: `{type: "ping"}`; optional `{type: "pong"}` handling; idle timeout closes with 1001.
+4. Error Handling
+   - Convert transport/iteration errors into structured frames via `stream.error(code, message, ...)`.
+   - Ensure exactly one terminal `done()` is emitted per stream on normal completion; no double‐DONE.
+5. Refactors (per‑module)
+   - Chat/Characters: replace `_extract_sse_data_lines` and local builders with `SSEStream`.
+   - Embeddings orchestrator: replace custom `yield f"event: ..."` with `SSEStream.send_event("summary", payload)` and heartbeat via abstraction.
+   - Audio WS: replace bespoke status/error frames where possible with `WebSocketStream.error/done/ping`; retain domain payloads.
+   - MCP WS: reuse `WebSocketStream` for ping loop and standardized error/done; keep JSON‑RPC responses intact.
+
+### 5.1 SSE Response Headers
+- Recommend headers to avoid buffering through proxies:
+  - `Cache-Control: no-cache`
+  - `Connection: keep-alive` (HTTP/1.1 only; HTTP/2 ignores this header)
+  - `X-Accel-Buffering: no` (for NGINX)
+  - Notes:
+    - Under HTTP/2, `Connection` is not meaningful and may be stripped; focus on disabling proxy buffering and keeping the response streaming (e.g., NGINX `proxy_buffering off;`, Caddy `encode`/`buffer` tuning).
+    - In reverse‑proxy/CDN environments (NGINX, Caddy, Cloudflare), prefer data heartbeats (`STREAM_HEARTBEAT_MODE=data`) to encourage flushes and reduce buffering.
+
+### 5.2 Provider Control/Event Pass-through
+- Normalization ignores `event:`/`id:`/`retry:` and comment lines by default.
+- Provide a provider-specific pass-through mode to preserve control fields when needed.
+- Emit debug logs when dropping unknown control lines during normalization to aid troubleshooting.
+- Global toggle: `STREAM_PROVIDER_CONTROL_PASSTHRU=1` enables pass-through (default off).
+- Per-endpoint flag: endpoints may request pass-through (e.g., `SSEStream(..., provider_control_passthru=True)`), which overrides the global default.
+
+- Transparent mode:
+  - When pass-through is enabled, preserve `event:`/`id:`/`retry:` lines and forward them unchanged alongside `data:` payloads.
+  - Add an optional hook for custom filtering/mapping (e.g., `control_filter(name: str, value: str) -> tuple[str, str] | None`) to rename/whitelist provider events.
+  - Intended for providers whose clients rely on SSE event names; default remains normalized mode.
+
+### 5.3 WS Event Frames Guardrails
+- Explicitly forbid wrapping domain WS payloads for MCP and Audio in `{type: "event"}` frames.
+- Only use event frames on endpoints designed for them; lifecycle frames (`ping`, `error`, `done`) remain standardized everywhere.
+- Add helper naming guidance and code review checklist item to reduce misuse.
+
+MCP JSON-RPC done semantics:
+- `done` is session-level only for MCP WebSockets. It must never be emitted as a JSON‑RPC message.
+- JSON‑RPC results/errors are sent as specified by JSON‑RPC; lifecycle frames (`ping`, `error`, session‑level `done`) are separate from JSON‑RPC content.
+
+### 5.4 Endpoint Examples (Rollout-friendly)
+
+```python
+# Audio WebSocket handler example with transitional error alias
+from tldw_Server_API.app.core.Streaming.streams import WebSocketStream
+
+async def audio_ws_handler(websocket):
+    stream = WebSocketStream(
+        websocket,
+        heartbeat_interval_s=10,
+        compat_error_type=True,   # include error_type alias during rollout
+        close_on_done=True,
+        labels={"component": "audio", "endpoint": "audio_ws"},
+    )
+    await stream.start()
+    try:
+        # Emit domain payloads directly (no event frames)
+        await stream.send_json({"type": "partial", "text": "..."})
+        # ...
+    except QuotaExceeded as e:
+        await stream.error("quota_exceeded", str(e), data={"limit": e.limit})
+        await stream.done()
+    finally:
+        await stream.stop()
+
+# MCP WebSocket: lifecycle frames standardized, JSON-RPC payloads unchanged
+async def mcp_ws_handler(websocket):
+    stream = WebSocketStream(
+        websocket,
+        heartbeat_interval_s=10,
+        compat_error_type=True,  # temporary alias for clients expecting error_type
+        close_on_done=False,      # MCP may manage session lifetime explicitly
+        labels={"component": "mcp", "endpoint": "mcp_ws"},
+    )
+    await stream.start()
+    try:
+        # Send JSON-RPC results as-is
+        await stream.send_json({"jsonrpc": "2.0", "result": {...}, "id": 1})
+        # ...
+    except Exception as e:
+        await stream.error("internal_error", f"{e}")
+    finally:
+        await stream.stop()
+```
+
+### 5.5 Backpressure Policy
+
+- Default: block on full SSE queue (no drops). Producers back off until the consumer drains the queue.
+- Optional mode: drop‑oldest (advanced; disabled by default). When enabled, the oldest queued item is dropped to make room for new items, and a counter increments for observability.
+- Recommendation: keep default blocking mode for correctness; only enable drop‑oldest for non‑critical high‑throughput streams with tolerant clients.
+ - Queue sizing guidance: Use a conservative default (e.g., 256 frames) and tune per endpoint based on typical payload size and client consumption rate. Track queue high‑water marks to inform tuning.
+
+### 5.7 Reverse Proxy & HTTP/2 Considerations
+
+- Heartbeats:
+  - Prefer `STREAM_HEARTBEAT_MODE=data` behind reverse proxies/CDNs to reduce buffering and encourage periodic flushes.
+  - Ensure proxy timeouts (read/idle) exceed heartbeat intervals.
+- Proxy buffering:
+  - Disable buffering on the reverse proxy (`proxy_buffering off;` for NGINX, appropriate Caddy/Envoy settings).
+  - For NGINX, keep `X-Accel-Buffering: no` on responses.
+- HTTP/1.1 vs HTTP/2:
+  - `Connection: keep-alive` applies to HTTP/1.1; HTTP/2 handles persistence differently and may strip the header.
+  - Do not rely on connection headers under HTTP/2; rely on correct streaming semantics and disabled buffering.
+
+### 5.6 SSE Idle/Max Duration Enforcement
+
+- Idle timeout (`STREAM_IDLE_TIMEOUT_S`):
+  - Behavior: emit error frame `{"error": {"code": "idle_timeout", "message": "idle timeout"}}` followed by `[DONE]`, then close.
+  - Client expectation: treat as terminal condition; retry logic is client‑specific.
+- Max duration (`STREAM_MAX_DURATION_S`):
+  - Behavior: emit error frame `{"error": {"code": "max_duration_exceeded", "message": "stream exceeded maximum duration"}}` followed by `[DONE]`, then close.
+  - Client expectation: treat as terminal condition; consider resuming in a new stream.
+
+---
+
+## 6. Dependencies & Impact
+
+- Reuse: `app/core/LLM_Calls/sse.py`, `app/core/LLM_Calls/streaming.py`.
+- Touchpoints: Chat endpoints, Character chat, Embeddings orchestrator SSE, Audio WS, MCP WS.
+- Docs: Update streaming sections in API docs and Audio/MCP protocol notes to mention standardized lifecycle frames.
+
+---
+
+## 7. Deletions & Cleanups
+
+- Remove endpoint‑local SSE helpers and duplicate DONE handling:
+  - `character_chat_sessions._extract_sse_data_lines`.
+  - Custom SSE yields in `embeddings_v5_production_enhanced.orchestrator_events` generator.
+- Replace bespoke heartbeat/error patterns in:
+  - `Audio_Streaming_Unified.handle_unified_websocket` (use `WebSocketStream` ping/error/done).
+  - `MCP_unified/server` ping loop and error frames where compatible with JSON‑RPC lifecycle.
+
+---
+
+## 8. Metrics & Success Criteria
+
+| Metric | Target |
+| --- | --- |
+| Duplicate DONE frames in Chat SSE | 0 across providers |
+| Stream error frames include `code` + `message` | 100% |
+| Heartbeat parity (SSE/WS) | Enabled by default, configurable |
+| Lines of duplicate streaming code removed | > 60% in affected files |
+| Server-side latency regression (enqueue→yield or send_json) | ≤ ±1% vs baseline |
+
+---
+
+## 9. Rollout Plan
+
+1. Phase 0 — Design (this document)
+   - Align on interface and semantics.
+2. Phase 1 — Abstraction + Chat pilot
+   - Implement `AsyncStream`, `SSEStream`, `WebSocketStream`.
+   - Migrate one Chat streaming endpoint; add unit tests for DONE/error/heartbeat.
+3. Phase 2 — Embeddings SSE
+   - Switch orchestrator SSE to `SSEStream`; keep `event: summary`.
+4. Phase 3 — Audio WS
+   - Integrate `WebSocketStream` for heartbeat/error/done; retain domain payloads.
+5. Phase 4 — MCP WS
+   - Use `WebSocketStream` ping/error where compatible; respect JSON‑RPC requirements.
+6. Phase 5 — Cleanup
+   - Delete endpoint‑local helpers; update docs/tests; enable by default.
+
+Feature flag: `STREAMS_UNIFIED` (default off for one release; then on by default).
+
+---
+
+## 9.1 Client Migration Checklist & Shims
+
+- WebUI and client libraries
+  - Update to consume `code` + `message` error shape; during rollout, accept `error_type` alias where present.
+  - Ignore `{type:"ping"}` frames; treat `{type:"done"}` as terminal.
+  - For SSE, handle `{"error": {"code", "message"}}` followed by `[DONE]` as terminal.
+- Audio/MCP integrations
+  - Keep domain payloads unchanged; enable `compat_error_type=True` on `WebSocketStream` during migration window.
+  - Standardize lifecycle handling: single source of pings; `done` where appropriate (avoid for JSON‑RPC content itself).
+- Observability
+  - Add dashboards for stream starts/stops/errors, WS close codes, SSE queue high‑water marks.
+  - Enable logs at `debug` for dropped control lines (when pass-through disabled) during the first release.
+- Feature flag playbook
+  - Roll out per‑endpoint; enable in pre‑prod/staging first.
+  - In case of regression, disable `STREAMS_UNIFIED` to revert to legacy code paths.
+  - Keep compatibility shims (`error_type`) until clients confirm migration.
+
+---
+
+## 10. Testing Strategy
+
+- Unit tests
+  - `SSEStream`: ensures normalization, exact one DONE, error payload shape, heartbeat interval.
+  - `WebSocketStream`: ping scheduling, error/done frames, close behavior.
+- Integration tests
+  - Chat SSE end‑to‑end with mock provider streams including provider `[DONE]` and malformed lines.
+  - Embeddings orchestrator SSE: event and heartbeat cadence.
+  - Audio WS: partial/final frames + standardized error/done in shutdown sequences.
+  - MCP WS: ping/idle timeout behavior with new helper.
+- Backward‑compat checks
+  - Snapshot tests for representative SSE/WS payload sequences before/after migration.
+- Latency measurement
+  - Instrument server-side latency: measure `enqueue→yield` for SSE (time from `send_*` to generator yield), and `send_json` call completion latency for WS. Compare distributions to baseline; target ≤ ±1%.
+- Backpressure tests
+  - SSE queue bounded behavior (block vs drop policy) with counters asserted.
+  - Heartbeats and backpressure: document that heartbeats share the same queue and may be delayed under heavy backpressure. Acceptance: without payload backpressure, observed heartbeat intervals stay within 2× configured; under saturation, heartbeats may be delayed but resume within 2× after backlog drains.
+
+---
+
+## 11. Risks & Mitigations
+
+- Risk: Subtle changes in timing/heartbeats can affect clients.
+  - Mitigation: feature flag; document intervals; snapshot test WebUI behavior.
+- Risk: Double DONE due to legacy code paths not removed.
+  - Mitigation: centralized suppression + unit tests; code search to remove duplicates.
+- Risk: MCP JSON‑RPC framing constraints.
+  - Mitigation: scope `WebSocketStream` usage to ping/error/done helpers; do not wrap JSON‑RPC result payloads.
+
+---
+
+## 12. Open Questions
+
+- Should `SSEStream.send_raw_sse_line` remain, or should hot paths convert lines to structured payloads for `send_json`? (current plan: keep `send_raw_sse_line` on `SSEStream` only; not part of `AsyncStream`).
+- Default heartbeat interval: 5s (as embeddings) vs 10s — choose one default with per‑endpoint override.
+
+---
+
+## 13. Acceptance Criteria
+
+- Chat SSE pilot endpoint emits standardized frames with no duplicate `[DONE]` across at least two providers.
+- Embeddings orchestrator emits `event: summary` via `SSEStream` with heartbeats controlled by config.
+- Audio WS adopts standardized `error` (code/message) and `done` frames and a single ping source; existing domain messages unchanged.
+- MCP WS uses shared ping/idle handling and `error/done` helpers where compatible.
+- Endpoint‑local SSE helpers removed; tests cover new abstraction; docs updated.
+
+---
+
+## 14. Configuration
+
+- `STREAMS_UNIFIED`: feature flag (off for one release; then default on)
+- `STREAM_HEARTBEAT_INTERVAL_S`: default 10
+- `STREAM_IDLE_TIMEOUT_S`: default disabled
+- `STREAM_MAX_DURATION_S`: default disabled
+- `STREAM_HEARTBEAT_MODE`: `comment` or `data` (default `comment`)
+- `STREAM_PROVIDER_CONTROL_PASSTHRU`: `0|1` (default `0`), preserves provider SSE control fields when `1`
+
+---
+
+## 15. Implementation Plan
+
+Stage 0 — Finalize Design and Defaults
+- Goal: Lock interface, defaults, metrics, and headers guidance.
+- Deliverables:
+  - Error semantics (code + message), heartbeat modes, close code mapping confirmed.
+  - Defaults: `STREAM_HEARTBEAT_INTERVAL_S=10`, `STREAM_HEARTBEAT_MODE=comment` (use `data` behind reverse proxies), SSE queue size target (~256), `STREAM_PROVIDER_CONTROL_PASSTHRU=0`.
+  - Metrics catalog confirmed; labels policy (low-cardinality: component, endpoint) approved.
+- Success: PRD approved; tracking issue created for each stage.
+
+Stage 1 — Core Abstractions + Metrics (this PR/commit)
+- Goal: Implement `SSEStream` and `WebSocketStream` with metrics hooks and labels.
+- Code:
+  - `tldw_Server_API/app/core/Streaming/streams.py` — abstractions, heartbeats, error/done, WS pings, metrics (`sse_enqueue_to_yield_ms`, `ws_send_latency_ms`, `sse_queue_high_watermark`, `ws_pings_total`, `ws_ping_failures_total`, `ws_idle_timeouts_total`).
+  - `tldw_Server_API/app/core/LLM_Calls/sse.py` — debug logs for dropped control/comment lines.
+- Tests:
+  - `tldw_Server_API/tests/Streaming/test_streams.py` — basic SSE/WS behavior; expand to cover labels presence later.
+- Docs:
+  - This PRD, Chat/Audio code docs examples, Metrics README (+ Grafana JSON).
+- Success: Unit tests pass; example code compiles; metrics exported without errors when registry is enabled.
+
+Stage 2 — Add Provider Control Pass-through + SSE Idle/Max Enforcement
+- Goal: Implement optional pass-through and SSE timers per PRD.
+- Code:
+  - Add `provider_control_passthru: bool` and optional `control_filter` hook to `SSEStream`; thread env `STREAM_PROVIDER_CONTROL_PASSTHRU`.
+  - Add optional idle/max duration timers to `SSEStream`; on trigger, emit error per 5.6 then `[DONE]` and close.
+  - Consider adjusting default `queue_maxsize` to 256 (as per 5.5 guidance).
+- Tests:
+  - Pass-through on/off snapshots; control filter mapping.
+  - Idle and max duration enforcement cases (timeouts emit error + DONE).
+- Success: Behavior matches PRD; no regressions in Chat SSE snapshots.
+
+Stage 3 — Chat SSE Pilot Integration
+- Goal: Migrate one Chat streaming endpoint to `SSEStream` behind `STREAMS_UNIFIED` flag.
+- Code:
+  - Replace endpoint-local SSE helpers (e.g., `_extract_sse_data_lines`) with `SSEStream` usage and headers.
+  - Route provider lines via `LLM_Calls/streaming.py` normalization.
+- Tests:
+  - End-to-end chat SSE with at least two providers; no duplicate `[DONE]`.
+  - Snapshot payloads pre/post match (except standardized error/heartbeat cadence).
+- Success: Feature-flagged pilot works with WebUI; latency within server-side target.
+
+Stage 4 — Embeddings SSE Migration
+- Goal: Move orchestrator events to `SSEStream` while preserving `event: summary`.
+- Code:
+  - Replace custom `yield f"event: ..."` with `send_event("summary", payload)`; heartbeats via abstraction.
+- Tests:
+  - Event cadence and heartbeats; summary payload unchanged; pass-through remains disabled unless explicitly needed.
+- Success: No client changes required; metrics visible in dashboard.
+
+Stage 5 — Audio WS Standardization
+- Goal: Adopt `WebSocketStream` for lifecycle (ping, error, done) without changing domain payloads.
+- Code:
+  - Wrap handler to use `WebSocketStream(..., compat_error_type=True)` during rollout.
+  - Standardize idle timeout close (1001); ping loop uses abstraction; retain domain messages.
+- Tests:
+  - Ping schedule, idle timeout counter increments, error/done frames, backwards-compatible error fields.
+- Success: Clients unaffected; improved observability in streaming dashboard.
+
+Stage 6 — MCP WS Lifecycle Adoption
+- Goal: Use `WebSocketStream` for ping/idle/error; never wrap JSON‑RPC content or emit `done` as JSON‑RPC.
+- Code:
+  - Integrate ping loop and standardized error close mapping; keep JSON‑RPC untouched.
+- Tests:
+  - Ping behavior, idle timeout (1001), errors with `code` and (`error_type` during rollout if needed).
+- Success: MCP dashboard unchanged for content; lifecycle metrics added.
+
+Stage 7 — Cleanup, Docs, and Flip Default
+- Goal: Remove endpoint-local helpers, update docs, and flip `STREAMS_UNIFIED` default.
+- Code:
+  - Delete duplicative SSE helpers; unify DONE suppression.
+  - Flip feature flag default to ON after one release; guard with rollback instructions.
+- Docs:
+  - API docs, Audio/MCP protocol notes, migration notes for `error_type` deprecation.
+- Success: Unified streams become the default with rollback path; client migrations completed.
+
+Risk Mitigation & Rollback
+- Feature flag per endpoint; can revert to legacy implementation immediately if regressions occur.
+- Keep `error_type` alias during rollout; remove after clients confirm.
+- Monitor dashboards: p95 WS send latency, SSE enqueue→yield p95, idle timeouts, ping failures; react to anomalies.
+
+Ownership & Tracking
+- Create issues per stage with checklists:
+  - Code changes with file paths
+  - Tests added/updated
+  - Docs touched
+  - Rollout/flag steps
+  - Validation (dashboards/alerts)

+PRD: HTTP Client Consolidation
+
+  - Owner: Platform / Core
+  - Version: 1.0
+  - Status: Proposed
+
+  Overview
+
+  - Unifying principle: Every outbound call is the same thing — an egress-validated HTTP request with retries.
+  - Objective: Consolidate all outbound HTTP across the codebase onto a single, secure, configurable client layer with consistent retry/backoff, timeouts, and egress enforcement.
+
+  Problem
+
+  - Duplication and inconsistency:
+      - Central client underused: tldw_Server_API/app/core/http_client.py:1
+      - Local LLM utils async client + custom retries: tldw_Server_API/app/core/Local_LLM/http_utils.py:41
+      - TTS allocates raw httpx.AsyncClient pools: tldw_Server_API/app/core/TTS/tts_resource_manager.py:200
+      - Summarization uses requests + urllib3.Retry: tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:629
+      - Streaming helpers mix requests and httpx directly: tldw_Server_API/app/core/LLM_Calls/streaming.py:18
+  - Impact:
+      - Inconsistent timeouts, retries, proxy handling.
+      - Partial/uneven enforcement of egress/SSRF policy (policy engine exists at tldw_Server_API/app/core/Security/egress.py:146).
+      - Hard to audit and monitor egress uniformly.
+
+  Goals
+
+  - One canonical way to:
+      - Create HTTP clients (create_client / create_async_client)
+      - Perform requests (fetch/afetch, JSON helpers, streaming, downloads)
+  - Always enforce egress policy for every outbound call.
+  - Centralize retry/backoff with sensible defaults and per-call overrides.
+  - Standardize timeouts, proxy handling (trust_env=False by default), HTTP/2 preference.
+  - Preserve or improve performance (keep-alive, pooling).
+  - Provide minimal, consistent logging and metrics for egress.
+
+  Non‑Goals
+
+  - Rewriting provider-specific business logic.
+  - Changing public API contracts beyond consistent network behavior.
+  - Introducing new network dependencies by default (curl backend remains optional).
+  - Global concurrency/rate limiting helper; tracked separately and out of scope for this PRD.
+
+  Stakeholders
+
+  - Platform/Core, Security, LLM Integrations, Media Ingestion, TTS, RAG/Search.
+
+  Current State
+
+  - Central client exists with egress guard and basic fetch: tldw_Server_API/app/core/http_client.py:1
+  - Egress policy engine: tldw_Server_API/app/core/Security/egress.py:146
+  - Multiple local retry/backoff implementations and direct httpx/requests usages across modules.
+
+  Proposed Solution
+
+  - Expand http_client with unified, secure primitives and require all modules to use them:
+      - Factories: create_client(...), create_async_client(...) (timeouts, limits, base_url, proxies, trust_env default false)
+      - Request helpers:
+          - Sync: fetch(...), fetch_json(...), stream(...)
+          - Async: afetch(...), afetch_json(...), astream(...)
+          - Download: download(...), adownload(...) (streaming, atomic rename)
+      - Retry/backoff: centralized policy with exponential backoff + jitter, Retry-After support, idempotency-aware retry by default.
+      - Egress: mandatory evaluate_url_policy(url) check inside all helpers prior to network I/O.
+      - Observability: log retries with redacted headers; optional metrics hooks.
+
+  Functional Requirements
+
+  - Client factories
+      - Accept: timeout, limits (httpx.Limits), base_url, trust_env (default false), proxies, http2=True, http3=False.
+      - Return httpx.Client / httpx.AsyncClient (or optional curl backend for sync fetch path already supported by fetch).
+      - Defaults:
+          - Timeout: connect=5s, read=30s, write=30s, pool=30s.
+          - Limits: max_connections=100, max_keepalive_connections=20.
+  - Requests
+      - fetch/afetch: method, url, headers, params, json, data, files, timeout, allow_redirects, proxies, retry.
+      - fetch_json/afetch_json: JSON parse with clear errors on non-JSON or invalid payloads; validate Content-Type is application/json unless accept_mismatch=True; optional max_bytes guard.
+      - Streaming helpers:
+          - astream_bytes(...): async iterator of raw bytes/chunks.
+          - astream_sse(...): async iterator of parsed SSE events with fields (event, data, id, retry).
+      - download/adownload: stream to temp path and atomic rename, clean partial on failure.
+      - Headers/UA: standardize User-Agent as "tldw_server/ ()" with per-call override; auto-inject X-Request-Id when present in context.
+      - Cookies: no first-class cookie jar helpers; callers may attach cookies via client configuration if needed.
+  - Egress policy
+      - Call evaluate_url_policy(url) first; deny with clear error when disallowed.
+      - Honor env-based allow/deny lists, scheme/port rules, and private/reserved IP blocking.
+      - Enforce at all phases: evaluate original URL, each redirect hop (see redirect policy), and the resolved IP post-DNS; deny on scheme/host/IP violations.
+      - Apply policy to proxies as well; only allow explicitly allowlisted proxies.
+  - Redirect policy
+      - Limit redirects to 5; re-check egress policy for each hop and validate the final URL and (optionally) expected Content-Type.
+  - Retry/backoff
+      - Defaults: attempts=3, exponential backoff with decorrelated jitter; base 250ms, cap 30s.
+      - Retry on: 408, 429, 500, 502, 503, 504, and connect/read timeouts.
+      - Respect Retry-After and provider-specific backoff headers; do not retry unsafe methods unless retry_on_unsafe=True.
+      - Streams: never auto-retry once any response body bytes have been consumed; allow optional user callback to opt in for segmented protocols.
+  - Observability
+      - Structured logs: request_id, method, scheme, host, path, status_code, duration_ms, attempt, retry_delay_ms, exception_class; redact sensitive headers and query params by default.
+      - Metrics (Prometheus style): http_client_requests_total{method,host,status}, http_client_request_duration_seconds_bucket, http_client_retries_total{reason}, http_client_egress_denials_total{reason}.
+      - Optional OpenTelemetry: inject/extract trace context (traceparent) and emit spans for requests and retries.
+  - JSON helpers
+      - Enforce Content-Type validation by default; configurable via accept_mismatch flag; optional max_bytes limit for decode.
+  - Download safety
+      - Optional checksum validation (sha256, configurable algorithm), Content-Length validation, and disk quota guard.
+      - Optional Range-resume capability behind a feature flag when server supports Range requests.
+
+  Non‑Functional Requirements
+
+  - Security by default: fail closed on egress evaluation errors; trust_env=False default.
+  - Performance: reuse pooled connections; support HTTP/2; ensure no regression in TTS/LLM throughput.
+  - Testability: functions accept injected clients and are easily mockable.
+  - Lifecycle: document safe client usage patterns (e.g., one AsyncClient per event loop for long‑lived services); provide context managers and a shared‑pool accessor for high‑QPS modules (TTS/LLM).
+  - Transport/TLS:
+      - HTTP/2 enabled by default; HTTP/3 (QUIC) supported behind a flag and only where the stack supports it.
+      - TLS minimum version enforcement is optional (disabled by default) and configurable (e.g., TLS 1.2+).
+      - Optional certificate pinning (SPKI SHA‑256 fingerprints) supported but off by default.
+
+  API Additions (in http_client)
+
+  - Types
+      - RetryPolicy: attempts, backoff_base_ms, backoff_cap_s, retry_on_status, retry_on_methods, respect_retry_after.
+      - TLSOptions (optional): enforce_min_version: bool, min_version: {"1.2","1.3"}, cert_pins_spki_sha256: Optional[Set[str]].

+
+  Security & Egress
+
+  - Centralized guard: evaluate_url_policy in every helper prior to I/O (tldw_Server_API/app/core/Security/egress.py:146).
+  - Deny unsupported schemes, disallowed ports, denylisted hosts, and private/reserved IPs unless env allows.
+  - Maintain SSRF-safe defaults; proxies only when explicitly configured.
+
+  Observability & Metrics
+
+  - Metrics (labels include method, status, backend):
+      - egress_requests_total
+      - egress_request_duration_ms
+      - egress_retries_total
+      - egress_policy_denied_total
+  - Logging: INFO on final failure, DEBUG on retries, with redacted headers.
+
+  Migration Plan
+
+  - Phase 1: Foundations
+      - Implement afetch/astream/fetch_json and retry policy in http_client.
+      - Add env/config plumbing; unit tests (retry matrix, egress deny, JSON errors, streaming close, downloads).
+  - Phase 2: Early Adopters
+      - Local LLM: replace request_json and client factory with create_async_client + afetch_json (tldw_Server_API/app/core/Local_LLM/http_utils.py:41).
+      - TTS: construct clients via create_async_client(limits=...) in pool (tldw_Server_API/app/core/TTS/tts_resource_manager.py:200).
+      - HuggingFace local API calls: move to afetch (tldw_Server_API/app/core/LLM_Calls/huggingface_api.py:105).
+  - Phase 3: Broad Replacement
+      - Summarization lib: replace requests.Session + Retry usages with fetch/afetch (tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:629).
+      - Ingestion/OCR/Audio downloads: use download/adownload (tldw_Server_API/app/core/Ingestion_Media_Processing/Audio/Audio_Files.py:222, OCR/backends/*).
+      - Streaming: standardize on astream + existing SSE normalizers (tldw_Server_API/app/core/LLM_Calls/streaming.py:18).
+  - Phase 4: Cleanup
+      - Remove deprecated helpers and ad‑hoc clients.
+      - Update docs; add integration tests for rate limits and egress denials.
+
+  What Will Be Removed
+
+  - Local retry/backoff and session code (non-exhaustive):
+      - tldw_Server_API/app/core/Local_LLM/http_utils.py:47
+      - tldw_Server_API/app/core/TTS/tts_resource_manager.py:200
+      - tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:629
+      - Other scattered HTTPAdapter(Retry(...)) blocks and raw httpx instantiations in core/services.
+
+  Testing Strategy
+
+  - Unit tests
+      - Egress: allowed/denied schemes, ports, hosts, private/reserved IP; DNS resolution IP checks; per-redirect hop enforcement; proxy allowlist.
+      - Retry/backoff: attempts, decorrelated jitter bounds, Retry-After (delta-seconds and HTTP-date) behavior, status code matrix, idempotency.
+      - JSON: success, bad JSON, wrong content-type, max_bytes enforcement.
+      - Streaming: normal end, mid-stream error surfaced, cancellation propagation (CancelledError), proper close; SSE parsing.
+      - Download: atomic rename, partial cleanup, checksum and Content-Length validation, basic Range-resume (when enabled).
+      - Observability: metrics counters/labels update; structured logs redact secrets; optional OTel spans emitted when enabled.
+  - Integration tests
+      - Swap target modules to central helpers; validate same behavior via mock servers and test markers already used in repo.
+      - Redirect chains with mixed hosts; ensure egress rechecks and final content-type validation.
+
+  Risks & Mitigations
+
+  - Behavior drift on retries for non-idempotent methods
+      - Default: do not retry unsafe methods; require explicit opt-in.
+  - Throughput regressions (TTS/LLM)
+      - Preserve Limits and keep-alive; validate with benchmarks.
+  - Over-enforcement blocking legitimate calls
+      - Ensure env allowlists; provide clear error messages and tests.
+
+  Dependencies
+
+  - httpx (existing), optional curl_cffi for sync impersonation path.
+  - Loguru and metrics registry for observability (already present).
+  - Optional cryptography for SPKI SHA‑256 certificate pinning utilities (only when pinning is enabled).
+
+  Acceptance Criteria
+
+  - 100% of outbound HTTP in app/core and app/services uses http_client helpers or factories (documented exceptions only).
+  - All requests evaluate egress policy prior to I/O and fail closed when denied.
+  - Consistent retry/backoff observed across modules; tests cover 429/5xx and network failures.
+  - TTS/Local LLM throughput and latency not degraded.
+  - Duplicated retry/session code removed or shimmed with deprecation warnings.
+
+  Milestones & Timeline
+
+  - Week 1: Implement APIs + unit tests in http_client; land without consumers.
+  - Weeks 2–3: Early adopters and broad replacement (module-by-module PRs).
+  - Week 4: Cleanup, docs, final integration tests.
+
+  Open Questions
+
+  - Circuit breaker per host? Config hints exist; defer unless needed by SLOs.
+  - Dev ergonomics: rely on egress.py profile selection (permissive vs strict) or add a dedicated dev override?
+  - curl_cffi impersonation defaults: remain opt-in at call sites?
+
+  Appendix: Code References
+
+  - Central client (to expand): tldw_Server_API/app/core/http_client.py:1
+  - Egress policy: tldw_Server_API/app/core/Security/egress.py:146
+  - Duplicates to consolidate:
+      - tldw_Server_API/app/core/Local_LLM/http_utils.py:41
+      - tldw_Server_API/app/core/TTS/tts_resource_manager.py:200
+      - tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py:629
+      - tldw_Server_API/app/core/LLM_Calls/streaming.py:18
+
+  Implementation Plan (Detailed)
+
+  - Stage 0: Spec Finalization
+      - Confirm PRD decisions for TLS min version (optional), HTTP/3 flag, proxy allowlist, streaming contracts, and exception taxonomy.
+      - Document configuration keys and defaults; align README and Config_Files/README.md.
+      - Success: PRD updated; config keys listed; stakeholders sign-off.
+
+  - Stage 1: Core API Foundations
+      - Implement unified helpers in http_client:
+          - Factories: create_client, create_async_client (timeouts, limits, headers, http2, trust_env, proxies validation).
+          - Requests: fetch/afetch with manual redirect handling; egress enforced per hop and on proxies.
+          - JSON: fetch_json/afetch_json with content-type validation and max_bytes guard.
+          - Streaming: astream_bytes and astream_sse with cancellation propagation; no auto-retry post-first byte.
+          - Downloads: download/adownload with atomic rename, checksum/length validation, optional resume.
+          - Exceptions: EgressPolicyError, NetworkError, RetryExhaustedError, JSONDecodeError, StreamingProtocolError, DownloadError.
+      - Observability:
+          - Structured retry logs (redacted headers) and basic request duration metrics.
+          - Optional traceparent injection from active span.
+      - Security:
+          - Enforce egress on original URL, redirect hops, and post-DNS IP; proxy allowlist (deny-by-default).
+      - Success: Helpers compile with tests; metrics registered; defaults respected via env.
+
+  - Stage 2: Unit Tests and Validation
+      - Add httpx.MockTransport tests covering: retry/backoff, egress deny, JSON validation, streaming SSE parse, download checksum/length, cancellation propagation.
+      - Add negative cases: redirect loops, redirect without Location, private/reserved IPs, proxy not allowlisted.
+      - Add metrics smoke tests to ensure counters/histograms increment and redact secrets in logs.
+      - Success: >90% coverage of http_client; green in CI across supported Python/httpx versions.
+
+  - Stage 3: Early Adopters Integration
+      - Replace direct HTTP calls in:
+          - Local LLM utilities: `tldw_Server_API/app/core/Local_LLM/http_utils.py` → create_async_client + afetch_json.
+          - TTS resource manager: `tldw_Server_API/app/core/TTS/tts_resource_manager.py` → pooled create_async_client with limits.
+          - HuggingFace/local API callers: `tldw_Server_API/app/core/LLM_Calls/huggingface_api.py` → afetch.
+      - Add adapters/shims where needed; keep behavior parity for timeouts and headers.
+      - Success: Modules work under new helpers; basic perf checks show no regressions.
+
+  - Stage 4: Broad Migration
+      - Summarization: migrate `tldw_Server_API/app/core/LLM_Calls/Summarization_General_Lib.py` from requests+Retry to fetch/afetch.
+      - Ingestion/Audio/OCR downloads: consolidate on download/adownload across ingestion backends and audio pipelines.
+      - Streaming call sites: standardize on astream_sse + existing SSE normalizers in `tldw_Server_API/app/core/LLM_Calls/streaming.py`.
+      - Success: Majority (>80%) of outbound HTTP uses helpers; regression tests pass.
+
+  - Stage 5: Observability & Security Hardening
+      - Ensure per-request structured logs include request_id, method, host, status, duration.
+      - Wire optional OpenTelemetry spans for client calls and retries; confirm traceparent propagation to providers that support it.
+      - Verify egress denials produce clear errors and increment `http_client_egress_denials_total` with reason.
+      - Success: Dashboards reflect client metrics; SLO alerts (if any) unaffected.
+
+  - Stage 6: Documentation & Examples
+      - Update developer docs with examples for fetch_json, SSE streaming, and downloads with checksum.
+      - Document configuration keys in Config_Files/README.md and .env templates; add migration tips for requests→httpx.
+      - Success: Docs merged; example snippets validated.
+
+  - Stage 7: Cleanup & Enforcement
+      - Remove deprecated local retry/session code and ad-hoc clients listed under "What Will Be Removed".
+      - Add a lightweight CI guard to flag direct `requests` or `httpx` usage outside `app/core/http_client.py` and tests.
+      - Success: 100% of outbound HTTP uses helpers (documented exceptions only); CI guard enforced.
+
+  - Rollout & Risk Mitigation
+      - Canary: enable helpers per-module behind lightweight toggles if needed; default to safe timeouts and trust_env=False.
+      - Fallback: ability to reduce http2 to http1 automatically if `h2` unavailable; keep curl backend opt-in.
+      - Rollback: revert module migrations individually (PR-by-PR) if regressions observed.
+
+  - Deliverables
+      - Code: unified http_client helpers + exceptions; module migrations; metrics wiring.
+      - Tests: unit tests for helpers; integration tests for migrated modules using mock servers.
+      - Docs: PRD updated; developer docs; migration notes.
+
+  - Acceptance Gates (per stage)
+      - Stage 1–2: Unit tests green; helpers stable across py/httpx versions; no secret leakage in logs.
+      - Stage 3–4: Early adopters and summarization/ingestion migrated with parity; perf smoke OK.
+      - Stage 5: Metrics visible and accurate; egress denials clear and tested.
+      - Stage 7: CI guard active; legacy code removed or wrapped with deprecation warnings.

+### Auth & Tokens
+- Token response shape: `access_token`, `refresh_token`, `token_type=bearer`, `expires_in` (seconds). Reference: `tldw_Server_API/app/api/v1/schemas/auth_schemas.py:181`.
+- Refresh rotation: if refresh call returns a `refresh_token`, replace the stored value (treat as authoritative).
+- Prefer header auth over cookies: use `Authorization: Bearer` or `X-API-KEY`; CSRF middleware is present but skipped for Bearer/X-API-KEY flows. Reference: `tldw_Server_API/app/main.py:2396`.
+- Service worker lifecycle: on background start, check for a stored refresh token and proactively refresh the access token (single-flight), so UI works after suspension/restart without prompting.

+### Streaming & SSE
+- Chat SSE: set `Accept: text/event-stream`; keep the service worker alive via a long‑lived `Port` from the side panel/popup; recognize `[DONE]` and release reader/locks.
+- RAG stream (NDJSON): tolerate heartbeats/blank lines and partial chunks; reassemble safe JSON boundaries before parse.
+- Cancellation: use `AbortController`; expect network to close within ≈200ms after abort.
+
+Note:
+- `/api/v1/rag/search/stream` requires `enable_generation=true` in the request body; otherwise the server returns HTTP 400.
+- Default retrieval knobs are `search_mode="hybrid"` and `top_k=10` unless overridden. Discover the server’s current defaults and ranges via `GET /api/v1/rag/capabilities`.

+### Media & Audio Details
+- STT multipart fields: `file` (UploadFile), `model` (default `whisper-1`), optional `language`, `prompt`, `response_format`, and TreeSeg controls (`segment`, `seg_*`). Allowed mimetypes include wav/mp3/m4a/ogg/opus/webm/flac; default max size ≈25MB (tiered). Reference: `tldw_Server_API/app/api/v1/endpoints/audio.py:464`.
+- TTS JSON body: `model`, `input` (text), `voice`, `response_format` (e.g., mp3, wav), optional `stream` boolean. Response sets `Content-Disposition: attachment; filename=speech.`. Reference: `tldw_Server_API/app/api/v1/endpoints/audio.py:272`.
+- Voices catalog: `GET /api/v1/audio/voices/catalog?provider=...` returns mapping of provider→voices; filter via `provider`. Reference: `tldw_Server_API/app/api/v1/endpoints/audio.py:1131`.
+- Media timeouts: adopt endpoint-specific timeouts similar to WebUI defaults (videos/audios ~10m, docs/pdfs ~5m). Reference: `tldw_Server_API/WebUI/js/api-client.js:290`.

+
+### Rate Limits & Backoff
+- Typical limits (subject to server config): RAG search ≈ 30/min, RAG batch ≈ 10/min, STT ≈ 20/min, TTS ≈ 10/min. Back off on 429 and honor the `Retry-After` header.
+- Show user-friendly retry timing (e.g., countdown) based on `Retry-After`. Avoid infinite retries on 5xx/network; cap attempts and use exponential backoff with jitter.
+
+References:
+- RAG limits: `tldw_Server_API/app/api/v1/endpoints/rag_unified.py` (limit_search 30/min, limit_batch 10/min)
+- STT limit: `tldw_Server_API/app/api/v1/endpoints/audio.py:461` (20/min)
+- TTS limit: `tldw_Server_API/app/api/v1/endpoints/audio.py` (10/min)
+
+Example (bounded backoff wrapper, MV3 background):
+```ts
+export async function backoffFetch(
+  input: RequestInfo,
+  init: RequestInit = {},
+  opts: { maxRetries?: number; baseDelayMs?: number } = {}
+): Promise {
+  const maxRetries = opts.maxRetries ?? 2; // keep small to avoid user surprise
+  const base = opts.baseDelayMs ?? 300;
+  let attempt = 0;
+  // Copy headers so we can mutate between retries
+  const headers = new Headers(init.headers || {});
+
+  while (true) {
+    let res: Response | null = null;
+    try {
+      res = await fetch(input, { ...init, headers });
+    } catch (e) {
+      // Network error: retry with backoff (bounded)
+      if (attempt >= maxRetries) throw e;
+      const jitter = 0.8 + Math.random() * 0.4;
+      await new Promise(r => setTimeout(r, Math.pow(2, attempt) * base * jitter));
+      attempt++; continue;
+    }
+
+    if (res.status === 429) {
+      // Honor Retry-After
+      const ra = res.headers.get('Retry-After');
+      const waitSec = ra ? Math.max(0, parseInt(ra, 10)) : Math.pow(2, attempt) * (base / 1000);
+      // Emit UI hint: next retry time (optional message bus)
+      // port?.postMessage({ type: 'retry-after', seconds: waitSec });
+      if (attempt >= maxRetries) return res; // surface to UI if we’ve already retried
+      await new Promise(r => setTimeout(r, waitSec * 1000));
+      attempt++; continue;
+    }
+
+    if (res.status >= 500 && res.status < 600) {
+      if (attempt >= maxRetries) return res; // bubble to UI
+      const jitter = 0.8 + Math.random() * 0.4;
+      await new Promise(r => setTimeout(r, Math.pow(2, attempt) * base * jitter));
+      attempt++; continue;
+    }
+
+    return res; // 2xx/3xx/4xx (non-429) -> caller handles
+  }
+}
+```
+
+#### Backoff + Auth Wrapper (centralized)
+```ts
+// Uses single-flight refresh + backoffFetch for rate limits and transient errors
+export async function apiFetch(
+  input: RequestInfo,
+  init: RequestInit = {},
+  opts: { backoff?: { maxRetries?: number; baseDelayMs?: number } } = {}
+): Promise {
+  const headers = new Headers(init.headers || {});
+  if (!headers.has('X-Request-ID')) headers.set('X-Request-ID', crypto.randomUUID());
+
+  // Attach auth
+  if (authMode === 'single_user') {
+    const { api_key } = await chrome.storage.local.get('api_key');
+    if (api_key) headers.set('X-API-KEY', api_key as string);
+  } else {
+    const token = await refreshAccessTokenSingleFlight();
+    headers.set('Authorization', `Bearer ${token}`);
+  }
+
+  const doFetch = () => backoffFetch(input, { ...init, headers }, opts.backoff);
+
+  // First attempt with current token/key and bounded backoff
+  let res = await doFetch();
+
+  // On 401, attempt a single refresh + retry (multi-user only)
+  if (res.status === 401 && authMode === 'multi_user') {
+    try {
+      const token = await refreshAccessTokenSingleFlight();
+      headers.set('Authorization', `Bearer ${token}`);
+      res = await doFetch();
+    } catch {
+      // Return original 401 if refresh fails
+    }
+  }
+  return res;
+}
+
+// Note: For SSE/NDJSON streaming, use the streaming helpers to initiate the
+// connection (optional single attempt with backoff on connect). Do not auto-retry
+// mid-stream to avoid duplicating streamed content.
+```
+
+### Notes/Prompts Concurrency & Shapes
+- Notes optimistic concurrency: `PUT/PATCH/DELETE /api/v1/notes/{id}` require the `expected-version` header. On HTTP 409, refetch the note to get the latest `version` and retry the operation with the updated header. Reference: `tldw_Server_API/app/api/v1/endpoints/notes.py:347`.
+- Notes search: `GET /api/v1/notes/search/?query=...` with optional `limit`, `offset`, `include_keywords`. Returns a list of notes (NoteResponse). The notes list endpoint (`GET /api/v1/notes/`) returns an object with `notes/items/results` aliases for back‑compat along with `count/limit/offset/total`. Reference: `tldw_Server_API/app/api/v1/endpoints/notes.py:480`.
+- Prompts keywords: create via `POST /api/v1/prompts/keywords/` with JSON `{ "keyword_text": "..." }`. Reference: `tldw_Server_API/app/api/v1/endpoints/prompts.py:240`.
+
+#### Quick Examples (curl)
+```bash

+## HTTP Client & Egress
+
+- All outbound HTTP calls are being consolidated on a unified `http_client` layer with security, retries, and observability baked in.
+- Egress policy is enforced before I/O, on each redirect hop, and for proxies. Private/reserved IPs are blocked by default.
+
+Key configuration (env)
+- Timeouts: `HTTP_CONNECT_TIMEOUT`, `HTTP_READ_TIMEOUT`, `HTTP_WRITE_TIMEOUT`, `HTTP_POOL_TIMEOUT`
+- Limits: `HTTP_MAX_CONNECTIONS`, `HTTP_MAX_KEEPALIVE_CONNECTIONS`
+- Retries: `HTTP_RETRY_ATTEMPTS`, `HTTP_BACKOFF_BASE_MS`, `HTTP_BACKOFF_CAP_S`
+- Redirects/Proxies: `HTTP_MAX_REDIRECTS`, `HTTP_TRUST_ENV`, `PROXY_ALLOWLIST`
+- JSON & Headers: `HTTP_JSON_MAX_BYTES`, `HTTP_DEFAULT_USER_AGENT`
+- Transport/TLS: `HTTP3_ENABLED`, `TLS_ENFORCE_MIN_VERSION`, `TLS_MIN_VERSION`, `TLS_CERT_PINS_SPKI_SHA256`
+- Egress policy: see `tldw_Server_API/app/core/Security/egress.py` (allow/deny/private IP envs)
+
+Basic usage
+```
+from tldw_Server_API.app.core.http_client import afetch_json, create_async_client
+
+async def fetch_items():
+    async with create_async_client() as client:
+        return await afetch_json(method="GET", url="https://api.example.com/items", client=client)
+```
+
+Notes
+- HTTP/2 is preferred, with automatic downgrade when `h2` is not installed. HTTP/3 is available behind a flag when supported.
+- Structured logs redact sensitive headers; metrics are exported when telemetry is configured.

+- Egress & SSRF policy
+  - All helpers evaluate the central egress policy (`app/core/Security/egress.py`) before any network I/O and on each redirect hop, and validate proxies.
+  - Denies unsupported schemes, disallowed ports, denylisted hosts, and private/reserved IPs by default. See `WORKFLOWS_EGRESS_*` env keys in that module for allow/deny behavior.
+
+- Observability
+  - Structured logs redact sensitive headers and may include `request_id`, `method`, `host`, `status`, `duration_ms`.
+  - Metrics (if telemetry enabled): `http_client_requests_total`, `http_client_request_duration_seconds`, `http_client_retries_total`, `http_client_egress_denials_total`.
+  - When tracing is active, `traceparent` header is injected automatically where supported.
+
+Example (Python)
+```
+from tldw_Server_API.app.core.http_client import create_async_client, afetch_json
+
+async with create_async_client() as client:
+    data = await afetch_json(method="GET", url="https://api.example.com/items", client=client)

+## Browser Extensions & Streaming
+
+If you are building a browser extension that calls the API (especially with Server-Sent Events via `Accept: text/event-stream`), add the extension origin to allowed CORS origins. In development:
+
+```bash
+# Example: allow a Chrome extension id (replace with your extension id)
+export ALLOWED_ORIGINS='["chrome-extension://abcd1234efgh5678", "http://localhost:8080", "http://127.0.0.1:8080"]'
+```
+
+Notes:
+- The server exposes `X-Request-ID`, `traceparent`, and `X-Trace-Id` headers for correlation. Ensure `expose_headers` includes these (already set by default when CORS is enabled).
+- Background/service worker fetches avoid most UX friction, but CORS still applies: the origin must be explicitly allowed.

 ### Prerequisites
-- TLDW Server API running (default: `http://localhost:8000`)
+- TLDW Server API (default: `http://localhost:8000`)
 - Modern web browser (Chrome, Firefox, Safari, Edge)
-- Python 3.x (for serving the WebUI)
 
-### Starting the WebUI
+### Starting the WebUI (Same-Origin, Recommended)
 
-1. **Start the API Server** (in one terminal):
+1. From the project root, launch the server and WebUI together:
    ```bash
-   cd /path/to/tldw_server
-   # Set your API key (if using single-user mode)
+   # Optionally set your API key (single-user mode)
    export SINGLE_USER_API_KEY="your-secret-api-key"
-   python -m uvicorn tldw_Server_API.app.main:app --reload
+   ./start-webui.sh
    ```
-   The API will be available at http://localhost:8000
 
-2. **Start the WebUI** (in another terminal):
-
-   **Option A: With Auto-Configuration (Recommended)**
-   ```bash
-   cd tldw_Server_API/WebUI
-   # The script will auto-detect SINGLE_USER_API_KEY from environment
-   ./Start-WebUI.sh
+2. Open your browser to:
    ```
-
-   **Option B: Manual Configuration**
-   ```bash
-   cd tldw_Server_API/WebUI
-   python3 -m http.server 8080
-   # You'll need to enter the API key manually in the UI
-   ```
-
-   **Option C: With Custom API URL**
-   ```bash
-   cd tldw_Server_API/WebUI
-   export API_URL="http://your-server:8000"
-   export SINGLE_USER_API_KEY="your-api-key"
-   ./Start-WebUI.sh
+   http://localhost:8000/webui/
    ```
 
-3. **Open your browser** and navigate to:
-   ```
-   http://localhost:8080
-   ```
-
-⚠️ **Important**: Do NOT open `index.html` directly in your browser (file:// protocol) as this will cause CORS errors. Always use an HTTP server.
+Notes:
+- The script gates first‑time setup at `/setup` and then serves the WebUI at `/webui/` on the same origin, avoiding CORS issues.
+- If the API server is already running, you can simply visit `http://localhost:8000/webui/` directly.

 - In production mode (`tldw_production=true`) or when `RAG_GUARDRAILS_STRICT=true`, the server defaults to enabling numeric fidelity and hard citations; you can still tighten behavior per request.
 
+## Performance & Maintainability
+
+- Per‑tab script loading: heavy JS is now loaded on demand when a tab is activated (audio, chat, prompts, etc.). This reduces initial load and keeps the code modular.
+- Inline handler migration: tabs are being refactored to remove inline `onclick` and related attributes. Newer panels (e.g., Flashcards → Manage) use delegated listeners bound in JS.
+- CSP tightening: once all inline handlers are removed, `unsafe-inline` can be dropped for `/webui` in CSP. Until then, inline use is minimized.
+- node_modules: do not commit `WebUI/node_modules` (already ignored). If any slipped into history, consider a history prune in a separate maintenance task. Local dev can run `npm i` inside `WebUI/` for tests (vitest), but this folder is not required at runtime.

 # Claims_Extraction
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: What Claims_Extraction extracts and why it exists.
-- Capabilities: Supported extraction types, formats, and sources.
-- Inputs/Outputs: Content inputs and extracted claims/metadata.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Extract and verify factual claims from generated answers and optionally overlay them into RAG streaming responses for grounding and citations.
+- Capabilities:
+  - LLM-based claim extraction with strict JSON parsing and safe fallbacks
+  - Heuristic sentence extractor; optional NER-assisted mode; APS-style propositions via Chunking strategy
+  - Hybrid verification: numeric/date heuristics, evidence retrieval, optional NLI, and LLM judge with citations and offsets
+  - RAG integration: incremental claims overlay events during streaming
+- Inputs/Outputs:
+  - Input: model answer text, user query, candidate context documents (or a retrieve function)
+  - Output: list of claims, per-claim verification labels (supported/refuted/nei), confidence, evidence snippets, citation offsets
+- Related Endpoints:
+  - Claims API: `tldw_Server_API/app/api/v1/endpoints/claims.py:1` (status, list, rebuild, rebuild_fts)
+  - RAG streaming (claims overlay): `tldw_Server_API/app/api/v1/endpoints/rag_unified.py:1176`, `tldw_Server_API/app/api/v1/endpoints/rag_unified.py:1348`
+- Related Engine/Libs:
+  - Core engine: `tldw_Server_API/app/core/Ingestion_Media_Processing/Claims/claims_engine.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Extractor pipeline and components.
-- Key Classes/Functions: Entry points and extraction interfaces.
-- Dependencies: Internal modules and external NLP/LLM services.
-- Data Models & DB: Storage schemas via `DB_Management`.
-- Configuration: Env vars and feature flags.
-- Concurrency & Performance: Batching, caching, rate limits.
-- Error Handling: Retries, backoff, failure modes.
-- Security: Input validation and safe processing.
+- Architecture & Data Flow:
+  - ClaimsEngine.run(answer, query, documents, …) orchestrates extraction then verification.
+  - Verification composes heuristics + optional retrieval + LLM judgment; citations computed via offset search.
+- Key Classes/Functions:
+  - `ClaimsEngine`, `LLMBasedClaimExtractor`, `HeuristicSentenceExtractor`, `HybridClaimVerifier` in `claims_engine.py`
+  - RAG overlay publisher in `rag_unified.py` emits `claims_overlay` events during streaming
+- Dependencies:
+  - Internal: `Utils.prompt_loader`, `RAG.rag_service.types.Document`, optional `Chunking.strategies.propositions`
+  - External (optional): `transformers` NLI pipeline; provider LLMs via unified analyze function
+- Data Models & DB:
+  - Claims persisted in per-user Media DB (tables `Claims`, FTS `claims_fts`); rebuild endpoints trigger maintenance
+- Configuration (env/config.txt):
+  - `CLAIMS_LLM_PROVIDER`, `CLAIMS_LLM_MODEL`, `CLAIMS_LLM_TEMPERATURE`; RAG fallbacks: `RAG.default_llm_provider`, `RAG.default_llm_model`
+  - Tuning: `claims_top_k`, `claims_conf_threshold`, `claims_max`, `claims_concurrency` (request-level)
+- Concurrency & Performance:
+  - Async extract/verify; bounded `claims_concurrency`; lightweight numeric/date heuristics short-circuit
+- Error Handling:
+  - Robust JSON extraction with fenced-block detection and heuristic fallback; verifier falls back on base docs when retrieval fails
+- Security:
+  - No network calls unless a provider/NLI is configured; inputs validated; respects AuthNZ and RBAC at API layer
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: Adding new extractors or heuristics.
-- Coding Patterns: DI, logging, rate limiting.
-- Tests: Where tests live; fixtures and sample data.
-- Local Dev Tips: Example inputs and debug flows.
-- Pitfalls & Gotchas: Ambiguity handling, deduplication.
-- Roadmap/TODOs: Planned improvements.
-
+- Folder Structure:
+  - Engine: `app/core/Ingestion_Media_Processing/Claims/claims_engine.py`
+  - API: `app/api/v1/endpoints/claims.py`
+- Extension Points:
+  - Add a new extractor (Protocol `ClaimExtractor`) or verifier (Protocol `ClaimVerifier`) and register in `ClaimsEngine`
+  - Inject custom `retrieve_fn` for domain-specific evidence selection
+- Coding Patterns:
+  - Use loguru for diagnostics; prefer async boundaries; avoid raw SQL (use DB_Management)
+- Related Tests:
+  - `tldw_Server_API/app/api/v1/endpoints/claims.py:1` (integration tests should cover list/rebuild behaviors)
+  - `tldw_Server_API/app/core/Ingestion_Media_Processing/Claims/claims_engine.py:1` (unit tests for extraction/verifier; see tracker TODOs)
+- Local Dev Tips:
+  - Enable claims in RAG requests, set `claims_top_k`/`claims_max` to small values while iterating
+- Pitfalls & Gotchas:
+  - Citation offset computation is best-effort; guard against long contexts and partial matches
+- Roadmap/TODOs:
+  - Property-based tests for offsets and numeric/date heuristics; tighten FTS rebuild reporting

 # Collections
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Manage grouped items and sets.
-- Capabilities: CRUD, search, tagging, and relations.
-- Inputs/Outputs: Collection definitions and views.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Unified content collections (reading list, outputs, tags) with search, filtering, and artifact generation.
+- Capabilities:
+  - Reading list: save URLs, list/filter, update status/favorite/tags
+  - Outputs: template CRUD, preview, artifact creation (md/html/mp3 via TTS), retention and purge
+  - Items: unified listing across Collections with legacy Media DB fallback
+  - Automatic embeddings enqueue on new/changed reading items
+- Inputs/Outputs:
+  - Inputs: URLs, metadata, item/job/run filters; template bodies and context
+  - Outputs: Content items, output templates, output artifacts on disk
+- Related Endpoints:
+  - Reading: `tldw_Server_API/app/api/v1/endpoints/reading.py:1`
+  - Items: `tldw_Server_API/app/api/v1/endpoints/items.py:1`
+  - Output Templates: `tldw_Server_API/app/api/v1/endpoints/outputs_templates.py:1`
+  - Outputs: `tldw_Server_API/app/api/v1/endpoints/outputs.py:1`

-- Security: Permissions and access control.
+- Architecture & Data Flow:
+  - Service: `core/Collections/reading_service.py` handles fetch, dedupe, persist, and embeddings enqueue
+  - API uses Collections DB via DI; legacy fallback to Media DB search to maintain compatibility
+- Key Classes/Functions:
+  - `ReadingService.save_url`, `.list_items`, `.update_item`
+  - `embedding_queue.enqueue_embeddings_job_for_item` (Redis-backed Embeddings JobManager)
+  - Templating: `Chat/prompt_template_manager.safe_render` for outputs
+- Dependencies:
+  - Internal: `DB_Management/Collections_DB`, `Embeddings/job_manager`, `Web_Scraping.Article_Extractor_Lib`
+  - External (optional): Redis for embeddings queue; provider TTS for mp3 outputs
+- Data Models & DB:
+  - `Collections_DB.py`: tables `output_templates`, `outputs`, `reading_highlights`, `content_items` (+ indices/uniques)
+- Configuration:
+  - Redis URL for embeddings queue: `EMBEDDINGS_REDIS_URL` or `REDIS_URL`
+- Concurrency & Performance:
+  - Background embeddings job per new/updated item
+  - Paging on list endpoints; FTS optional depending on backend
+- Error Handling:
+  - Safe fallbacks when outputs re-encode fails; DB backfills in schema initializer
+- Security:
+  - AuthNZ enforced at endpoints; per-user DB paths; soft-delete for outputs

-- Coding Patterns: DI, logging, metrics.
-- Tests: Where tests live; fixtures and examples.
-- Local Dev Tips: Example operations.
-- Pitfalls & Gotchas: Large collections and pagination.
-- Roadmap/TODOs: Planned improvements.
+- Folder Structure:
+  - `Collections/reading_service.py`, `embedding_queue.py`, `utils.py`; DB adapter in `DB_Management/Collections_DB.py`
+- Extension Points:
+  - Add new origins to `content_items`; extend outputs formats; add highlight strategies
+- Coding Patterns:

 # Infrastructure
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
+Centralized helpers for shared runtime infrastructure. Today this module focuses on Redis connectivity with a robust in‑memory fallback and metrics instrumentation. Other modules (Embeddings orchestrator, backpressure guards, rate limiting, privilege cache, MCP Unified) import clients exclusively via this package.
 
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Infrastructure-related helpers and abstractions.
-- Capabilities: Provisioning hooks, adapters, or infra helpers.
-- Inputs/Outputs: Configuration inputs and infra artifacts.
-- Related Endpoints: Link API routes (if any) and files.
-- Related Schemas: Pydantic models (if any).
+- Purpose: Provide a single, dependable factory for Redis clients (async and sync) with seamless fallback to an in‑memory stub when Redis is unavailable. Emits standard metrics for observability.
+- Capabilities:
+  - Async and sync Redis clients: `create_async_redis_client`, `create_sync_redis_client`.
+  - In‑memory stub with feature coverage for module needs: strings, hashes, sets, sorted sets, TTL, simple pipelines, streams (XADD/XRANGE/XLEN/XDEL), basic Lua script load/eval for rate‑limiter logic.
+  - Metrics: records connection attempts, durations, errors, and fallbacks via the Metrics registry.
+  - Graceful close helpers: `ensure_async_client_closed`, `ensure_sync_client_closed`.
+- Inputs/Outputs:
+  - Inputs: Optional `preferred_url`, config/env keys, `redis_kwargs` for SSL/password/etc.
+  - Outputs: A client exposing the subset of redis‑py API used by the codebase; either real Redis or the in‑memory stub.
+- Related Endpoints/Modules (usage examples):
+  - Backpressure dependency (Embeddings orchestrator depth/age): tldw_Server_API/app/api/v1/API_Deps/backpressure.py:16, tldw_Server_API/app/api/v1/API_Deps/backpressure.py:24
+  - Embeddings API (tenant RPS + DLQ admin): tldw_Server_API/app/api/v1/endpoints/embeddings_v5_production_enhanced.py:78, tldw_Server_API/app/api/v1/endpoints/embeddings_v5_production_enhanced.py:474
+  - Rate limiting (generic FastAPI dependency): tldw_Server_API/app/core/RateLimiting/Rate_Limit.py:14, tldw_Server_API/app/core/RateLimiting/Rate_Limit.py:36
+  - Character Chat rate limiting (sync client option): tldw_Server_API/app/core/Character_Chat/character_rate_limiter.py:556, tldw_Server_API/app/core/Character_Chat/character_rate_limiter.py:558
+  - Privilege maps cache invalidation (sync client): tldw_Server_API/app/core/PrivilegeMaps/cache.py:171
+  - MCP Unified distributed limiter: tldw_Server_API/app/core/MCP_unified/auth/rate_limiter.py:16
+- Related Schemas: N/A (this module exposes service clients, not Pydantic models).
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Boundaries and responsibilities.
-- Key Classes/Functions: Entry points and interfaces.
-- Dependencies: Internal modules and external services.
-- Data Models & DB: Any state persisted via `DB_Management`.
-- Configuration: Env vars and feature flags.
-- Concurrency & Performance: N/A or specifics.
-- Error Handling: Failure modes and retries.
-- Security: Permissions and secret handling.
+- Architecture & Data Flow:
+  - Caller requests a Redis client with optional `preferred_url` and `context` label.
+  - Factory resolves the URL (config/env precedence), attempts to connect/ping real Redis, and records metrics.
+  - On failure (or if redis is not installed) and when `fallback_to_fake=True`, it returns an in‑memory stub implementing the subset of Redis features used by the application.
+- Key Classes/Functions (entry points):
+  - `create_async_redis_client(preferred_url=None, decode_responses=True, fallback_to_fake=True, context="default", redis_kwargs=None)`
+  - `create_sync_redis_client(preferred_url=None, decode_responses=True, fallback_to_fake=True, context="default", redis_kwargs=None)`
+  - `ensure_async_client_closed(client)`, `ensure_sync_client_closed(client)`
+  - In‑memory clients: `InMemoryAsyncRedis`, `InMemorySyncRedis` (with thin pipeline helpers)
+- Dependencies:
+  - Optional runtime: `redis` / `redis.asyncio` (import‑guarded). When unavailable, factory can still return in‑memory clients.
+  - Metrics (optional during early startup): hooks into `tldw_Server_API.app.core.Metrics.metrics_manager.get_metrics_registry`.
+- Data Models & DB:
+  - No relational tables. Interacts with Redis using well‑known keys used by other modules, e.g.:
+    - Embeddings streams: `embeddings:chunking`, `embeddings:embedding`, `embeddings:storage`, plus `:dlq` variants.
+    - Rate limit counters: `rl:req:{user}:{window}`, `rl:tok:{user}:{YYYYMMDD}`.
+    - Tenant RPS: `embeddings:tenant:rps:{user}`, `ingest:tenant:rps:{user}:{ts}`.
+    - Privilege cache generation key/channel: e.g., `privilege:cache:generation`, `privilege:cache:invalidate`.
+- Configuration (precedence and keys):
+  - URL resolution: `preferred_url` arg → `settings.get('EMBEDDINGS_REDIS_URL')` → `settings.get('REDIS_URL')` → `ENV[EMBEDDINGS_REDIS_URL|REDIS_URL]` → default `redis://localhost:6379`.
+  - Module‑specific consumers may reference additional env/keys (e.g., backpressure limits `EMB_BACKPRESSURE_MAX_DEPTH`, `EMB_BACKPRESSURE_MAX_AGE_SECONDS`; privilege cache `PRIVILEGE_CACHE_REDIS_URL`).
+- Concurrency & Performance:
+  - In‑memory stubs are protected by an `asyncio.Lock` (async) or `threading.Lock` (sync) to avoid races when used concurrently.
+  - Streams and sorted‑set operations in the stub are implemented for the project’s use cases (XRANGE/XLEN/XADD; ZADD/ZCARD/ZREMRANGEBYSCORE), adequate for tests and single‑node dev.
+- Error Handling:
+  - Connection errors emit metrics and fall back to stub when allowed; callers can disable fallback via `fallback_to_fake=False` (raises the original error).
+  - Close helpers are best‑effort and safe to call on both real and stub clients.
+- Security:
+  - Secrets come from env or config; do not log credentials. Logs include a `context` label only.
+  - Fallback avoids external dependencies in CI/dev, keeping tests hermetic.
+- Metrics emitted (names defined in Metrics module):
+  - `infra_redis_connection_attempts_total{mode,context,outcome}`
+  - `infra_redis_connection_duration_seconds{mode,context,outcome}`
+  - `infra_redis_connection_errors_total{mode,context,error}`
+  - `infra_redis_fallback_total{mode,context,reason}`
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: Adding infra adapters or helpers.
-- Coding Patterns: DI, logging, metrics.
-- Tests: Where tests live; fixtures and fakes.
-- Local Dev Tips: Local simulation or stubs.
-- Pitfalls & Gotchas: Platform differences.
-- Roadmap/TODOs: Planned improvements.
+- Folder Structure:
+  - `redis_factory.py` — main factory and in‑memory client implementations.
+  - `__init__.py` — module docstring and export surface (import helpers from here).
+- Extension Points:
+  - Add new infra factories using the same pattern: centralized URL/config resolution, optional metrics, and an in‑memory stub when feasible.
+  - If extending the in‑memory Redis API surface, keep it minimal and driven by concrete caller needs; add tests.
+- Coding Patterns:
+  - Always import from `tldw_Server_API.app.core.Infrastructure.redis_factory`.
+  - Pass a meaningful `context` string to aid debugging/metrics.
+  - Use `ensure_async_client_closed`/`ensure_sync_client_closed` in `finally` blocks for real clients.
+- Tests:
+  - Metrics behavior tests: tldw_Server_API/tests/Infrastructure/test_redis_factory_metrics.py:17, tldw_Server_API/tests/Infrastructure/test_redis_factory_metrics.py:60, tldw_Server_API/tests/Infrastructure/test_redis_factory_metrics.py:108
+  - Embeddings orchestrator tests exercise streams/queues against the stub (e.g., DLQ/orchestrator snapshot): see tests under `tldw_Server_API/tests/Embeddings/`.
+- Local Dev Tips:
+  - No Redis running? Do nothing — the factory falls back to an in‑memory client automatically.
+  - To use a real Redis, set `REDIS_URL` (or `EMBEDDINGS_REDIS_URL`) and ensure `redis` extras are installed.
+  - Example (async):
+
+    ```python
+    from tldw_Server_API.app.core.Infrastructure.redis_factory import create_async_redis_client, ensure_async_client_closed
+
+    client = await create_async_redis_client(context="demo")
+    try:
+        await client.xadd("embeddings:embedding", {"doc_id": "123", "ev": "enqueue"})
+        depth = await client.xlen("embeddings:embedding")
+    finally:
+        await ensure_async_client_closed(client)
+    ```
+
+  - Example (sync):
+
+    ```python
+    from tldw_Server_API.app.core.Infrastructure.redis_factory import create_sync_redis_client
+
+    client = create_sync_redis_client(context="demo-sync")
+    client.incr("rl:req:demo:0")
+    ```
+- Pitfalls & Gotchas:
+  - In‑memory client does not implement full Redis feature parity. Pub/Sub is not available in the stub.
+  - If you rely on strict Redis behavior (e.g., exact stream IDs, ordering guarantees, Lua semantics), add integration tests with a real Redis and gate them via env.
+  - When `fallback_to_fake=False`, be prepared to handle connection exceptions during startup.
+- Roadmap/TODOs:
+  - Consider factories for additional infra (Postgres pool, object storage) following the same pattern.
+  - Expand metrics (pool usage, cache hit/miss) if/when additional factories are introduced.

 # Local_LLM
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details from the implementation and tests.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: What Local_LLM provides and why it exists.
-- Capabilities: Bullet list of supported features and behaviors.
-- Inputs/Outputs: Key inputs it accepts and outputs it produces.
-- Related Endpoints: Link primary API routes and files (if applicable).
-- Related Schemas: Link Pydantic models used for requests/responses.
+- Purpose: Manage local model backends (Llama.cpp, Llamafile, Ollama, HuggingFace) for offline/edge inference.
+- Capabilities:
+  - Start/stop servers (llama.cpp, llamafile), list local models, run inference (OpenAI-compatible payloads)
+  - Utilities for HTTP calls; unified manager to route requests to handlers
+- Inputs/Outputs:
+  - Input: backend name, model path/name, OpenAI-like inference payload
+  - Output: status dicts, inference results, metrics
+- Related Endpoints:
+  - Llama.cpp control/inference/rerank: `tldw_Server_API/app/api/v1/endpoints/llamacpp.py:1`
+- Related Schemas/Config:
+  - `tldw_Server_API/app/core/Local_LLM/LLM_Inference_Schemas.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Components, control flow, and boundaries.
-- Key Classes/Functions: Main entry points and where to start reading code.
-- Dependencies: Internal modules and external SDKs/services.
-- Data Models & DB: Tables/collections (via `DB_Management`) and indices.
-- Configuration: Env vars and config keys; defaults and precedence.
-- Concurrency & Performance: Async/threading, batching, caching, rate limits.
-- Error Handling: Custom exceptions, retries/backoff, failure modes.
-- Security: AuthNZ/permissions, input validation, safe file handling.
+- Architecture & Data Flow:
+  - `LLMInferenceManager` owns handler instances for each backend; delegates list/download/run/start/stop calls
+- Key Classes/Functions:
+  - Manager: `LLM_Inference_Manager.py`; base and handlers: `LLM_Base_Handler.py`, `LlamaCpp_Handler.py`, `Llamafile_Handler.py`, `Ollama_Handler.py`, `Huggingface_Handler.py`; `http_utils.py`
+- Dependencies:
+  - Backends binaries/servers; Python `transformers` optional for HF local inference flows
+- Data Models & DB:
+  - No persistent DB; handler state in-memory; models stored on disk under configured directories
+- Configuration:
+  - Handler-specific paths (models_dir, binary paths) via schemas/config; env toggles for enabling local provider
+- Concurrency & Performance:
+  - Process lifecycle management; streaming responses supported via server OpenAI-compatible APIs
+- Error Handling:
+  - Typed exceptions (`InferenceError`, `ServerError`, `ModelNotFoundError`); robust cleanup on exit
+- Security:
+  - Bind servers to safe interfaces; gate external access in production
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and their responsibilities.
-- Extension Points: How to add/extend local LLM backends or adapters.
-- Coding Patterns: DI, logging via loguru, rate limiting conventions.
-- Tests: Where tests live, fixtures to reuse, adding unit/integration tests.
-- Local Dev Tips: Quick start, example invocations, dummy configs.
-- Pitfalls & Gotchas: Known edge cases and performance traps.
-- Roadmap/TODOs: Near-term improvements and open questions.

-Example Quick Start (optional)
-
-```python
-# from tldw_Server_API.app.core.Local_LLM import SomeClass
-# svc = SomeClass(...)
-# result = svc.run(...)
-```
-
+- Folder Structure:
+  - `Local_LLM/` handlers and manager; `http_utils.py` helpers
+- Extension Points:
+  - Implement a new handler adhering to the manager contract and register in `LLMInferenceManager`
+- Coding Patterns:
+  - Loguru logging; keep endpoints thin and defer to manager/handlers
+- Tests:
+  - `tldw_Server_API/tests/Local_LLM/test_manager.py:1`
+  - `tldw_Server_API/tests/Local_LLM/test_llamafile_handler.py:1`
+  - `tldw_Server_API/tests/Local_LLM/test_llamafile_parity.py:1`
+  - `tldw_Server_API/tests/Local_LLM/test_llamacpp_handler.py:1`
+  - `tldw_Server_API/tests/Local_LLM/test_llamacpp_hardening.py:1`
+  - `tldw_Server_API/tests/Local_LLM/test_http_utils.py:1`
+- Local Dev Tips:
+  - Start llama.cpp/llamafile via endpoints; use small GGUF locally; verify `/llamacpp/status` and inference
+- Pitfalls & Gotchas:
+  - Port conflicts, long-running processes; ensure cleanup via `cleanup_on_exit`
+- Roadmap/TODOs:
+  - Expand parity of rerank/embeddings flows across backends

 # Moderation
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Content moderation and policy enforcement.
-- Capabilities: Classification, filtering, and reporting.
-- Inputs/Outputs: Content inputs and moderation decisions.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Centralized, configurable moderation/guardrails for chat inputs/outputs with support for redaction or blocking.
+- Capabilities:
+  - Global policy from config.txt ([Moderation]) with per-user runtime overrides
+  - Blocklist with literals/regex, per-rule action (block|warn|redact:replacement)
+  - Categories filter and optional built-in PII patterns
+  - Streaming-friendly redaction and graceful block handling
+- Inputs/Outputs:
+  - Input: text (request/response frames)
+  - Output: moderated text or block/warn signals
+- Related Usage:
+  - Chat endpoints depend on moderation service for pre/post filtering

 # PrivilegeMaps
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Mapping actions to roles/permissions.
-- Capabilities: Privilege evaluation and enforcement.
-- Inputs/Outputs: Subject, resource, action → decision.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Introspect FastAPI route dependencies to map scopes, RBAC, and rate-limit resources; aggregate into org/team/user summaries.
+- Capabilities:
+  - Route registry extraction and serialization
+  - Role-scope mapping using catalog; admin roles and feature flags
+  - Cached summaries with time-series trend store
+- Inputs/Outputs:
+  - Input: FastAPI app instance + privilege catalog
+  - Output: per-scope route maps, summaries, trends, and cached snapshots
+- Related Usage:
+  - Used by admin/reporting endpoints and docs tooling
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Policy evaluation strategy and flow.
-- Key Classes/Functions: Entry points and policy stores.
-- Dependencies: Internal modules and external auth systems.
-- Data Models & DB: Storage schemas via `DB_Management`.
-- Configuration: Env vars and feature flags.
-- Concurrency & Performance: Caching and fast paths.
-- Error Handling: Denials, fallbacks, audits.
-- Security: Least privilege, defense in depth.
+- Architecture & Data Flow:
+  - `collect_privilege_route_registry(app, catalog)` extracts dependencies and scope matches; `PrivilegeMapService` builds summaries with cache + trends
+- Key Classes/Functions:
+  - Service: `PrivilegeMaps/service.py:1`; Introspection: `PrivilegeMaps/introspection.py:1`; Startup hooks: `PrivilegeMaps/startup.py:1`; Caching/Trends helpers
+- Dependencies:
+  - Internal: AuthNZ settings, privilege catalog loader, caching store
+- Data Models & DB:
+  - In-memory caches by default; optional stores pluggable
+- Configuration:
+  - Cache TTL: `PRIVILEGE_MAP_CACHE_TTL_SECONDS` (default 120s)
+- Concurrency & Performance:
+  - Deterministic route signature to invalidate caches on changes
+- Error Handling:
+  - Unknown scope refs logged; strict mode raises on collection
+- Security:
+  - Admin roles set maintained; summaries respect RBAC design

 # Sandbox
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Safe execution boundaries and isolation.
-- Capabilities: Sandboxed operations, policies, constraints.
-- Inputs/Outputs: Inputs allowed and outputs produced.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: An isolated execution scaffold with sessions, queued runs, idempotency, and artifact streaming.
+- Capabilities:
+  - Create/destroy sessions; upload files to session
+  - Queue runs with TTL and capacity limits; cancelation support
+  - Stream run events via WebSocket; secure artifact download URLs
+- Inputs/Outputs:
+  - Inputs: JSON payloads for sessions/runs; file uploads; WS control frames
+  - Outputs: run statuses, artifacts, stream frames, health states
+- Related Endpoints:
+  - `tldw_Server_API/app/api/v1/endpoints/sandbox.py:82` (router + endpoints: health, sessions, runs, stream, admin)
+- Related Models:
+  - `tldw_Server_API/app/api/v1/schemas/sandbox_schemas.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Isolation mechanisms and flow control.
-- Key Classes/Functions: Entry points and policy engines.
-- Dependencies: Internal modules and external tools.
-- Data Models & DB: Persisted state via `DB_Management`.
-- Configuration: Env vars and feature flags.
-- Concurrency & Performance: Resource limits and scheduling.
-- Error Handling: Policy violations, timeouts, failures.
-- Security: Permissions, isolation guarantees, audits.
+- Architecture & Data Flow:
+  - `SandboxOrchestrator` manages sessions, runs, idempotency storage via `store`; queue pruning by TTL
+- Key Classes/Functions:
+  - Orchestrator: `core/Sandbox/orchestrator.py:1`; Policy/config in `core/Sandbox/policy.py`; store/cache/streams modules
+- Dependencies:
+  - Internal: Metrics counters; Audit logging; feature flags
+- Data Models & DB:
+  - In-memory store by default (pluggable via `store`)
+- Configuration:
+  - Queue: `SANDBOX_QUEUE_MAX_LENGTH`, `SANDBOX_QUEUE_TTL_SEC`, `SANDBOX_QUEUE_ESTIMATED_WAIT_PER_RUN_SEC`

-
+- Folder Structure:
+  - `Sandbox/` with `models.py`, `orchestrator.py`, `service.py`, `store.py`, `streams.py`, `policy.py`, runner stubs
+- Extension Points:
+  - Implement durable stores and real runners (docker/firecracker runners are stubs here)
+- Coding Patterns:
+  - Keep API thin; push logic into orchestrator/service; add metrics/audit labels consistently
+- Tests:
+  - (Scaffold) Add end-to-end tests using WS and queue limits as the module matures
+- Local Dev Tips:
+  - Use `/api/v1/sandbox/health` and `/api/v1/sandbox/runs` for quick validation; enable synthetic test frames in config when available
+- Pitfalls & Gotchas:
+  - Queue backpressure and TTL pruning; large artifact payloads
+- Roadmap/TODOs:
+  - Pluggable backends for store and runners; per-tenant quotas

 # Setup
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details from the implementation and tests.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: What Setup handles and why it exists.
-- Capabilities: Initialization routines, environment preparation, migrations.
-- Inputs/Outputs: Config inputs and setup artifacts/outputs.
-- Related Endpoints: Link API routes (if any) and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Centralize first-time setup and config management (config.txt), and define install plans for STT/TTS/Embeddings.
+- Capabilities:
+  - Read/update `config.txt` with section labels, hints, and diff-safe writes
+  - Toggle remote setup access and propagate via hook
+  - Define validated install plans for STT/TTS/Embeddings
+- Inputs/Outputs:
+  - Inputs: form-like updates to config fields; install plan models
+  - Outputs: persisted config.txt and install plan DTOs
+- Related Schemas:
+  - `tldw_Server_API/app/core/Setup/install_schema.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Initialization steps and dependencies.
-- Key Classes/Functions: Entry points and CLI hooks.
-- Dependencies: Internal modules and external tools.
-- Data Models & DB: Migrations/helpers via `DB_Management`.
-- Configuration: Env vars and config keys.
-- Concurrency & Performance: Considerations for setup processes.
-- Error Handling: Failure modes and retries.
-- Security: Secret handling and permissions.
+- Architecture & Data Flow:
+  - `setup_manager.py` reads/writes config with placeholder detection; `install_manager.py` manages dependency checks/installs
+- Key Classes/Functions:
+  - `register_remote_access_hook`, section label/description maps, field hints, diff helpers
+  - Install models: `InstallPlan`, `STTInstall`, `TTSInstall`, `EmbeddingsInstall`
+- Dependencies:
+  - Standard library; optional pip invocation via controlled gates
+- Data Models & DB:
+  - No DB; files under `Config_Files/`
+- Configuration:
+  - `TLDW_SETUP_SKIP_PIP` to block installs; env for default engines and models
+- Concurrency & Performance:
+  - File IO only
+- Error Handling:
+  - Safe fallbacks for missing sections; placeholder detection to prevent accidental secrets commit
+- Security:
+  - Sensitive key markers; never log secrets; anchor relative paths to project root
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: Adding new setup routines.
-- Coding Patterns: Logging, idempotency, and guards.
-- Tests: Where tests live and fixtures to reuse.
-- Local Dev Tips: Running setup locally and validation steps.
-- Pitfalls & Gotchas: Platform diffs and order dependencies.
-- Roadmap/TODOs: Planned setup improvements.
-
+- Folder Structure:
+  - `Setup/setup_manager.py`, `install_manager.py`, `install_schema.py`
+- Extension Points:
+  - Add new sections/labels/hints; extend installers for new engines
+- Coding Patterns:
+  - Keep config mutations idempotent and minimal; use helper utilities for diffing
+- Tests:
+  - (Add targeted tests for diff/hints as features expand)
+- Local Dev Tips:
+  - Use a temp copy of `Config_Files/config.txt` while iterating
+- Pitfalls & Gotchas:
+  - Placeholder values should be replaced; handle OS-specific paths
+- Roadmap/TODOs:
+  - Expose minimal setup APIs and UI helpers

 # Sync
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
+Two‑way synchronization between a client’s local Media DB and the server’s per‑user Media DB. Provides a client library and server endpoints to push local changes and fetch remote deltas, with batching, idempotency, and conflict resolution.
 
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Synchronization and replication tasks.
-- Capabilities: Sync jobs, conflict resolution, and status tracking.
-- Inputs/Outputs: Source/target inputs and sync results.
-- Related Endpoints: Link API routes (if any) and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Keep local client state (SQLite) and the server’s user‑scoped database consistent via an append‑only `sync_log` with incremental change IDs.
+- Capabilities:
+  - Client engine: push local changes, pull remote changes, apply in a single transaction, and persist progress markers in a state file.
+  - Server endpoints: accept client changes, apply with authoritative timestamps, return filtered deltas to the requesting client.
+  - Conflict handling: last‑write‑wins (LWW) using server authoritative timestamps; idempotency for duplicate/older updates.
+  - Batching and limits: configurable batch size for push/pull; efficient stream processing.
+- Inputs/Outputs:
+  - Inputs: `SyncLogEntry` records (entity, uuid, operation, version, timestamp, payload, client_id), client progress markers.
+  - Outputs: server responses with `changes: List[SyncLogEntry]` and `latest_change_id` for the user’s log.
+- Related Endpoints:
+  - POST `/api/v1/sync/send` — tldw_Server_API/app/api/v1/endpoints/sync.py:83
+  - GET `/api/v1/sync/get` — tldw_Server_API/app/api/v1/endpoints/sync.py:129
+  - Router mount — tldw_Server_API/app/main.py:3037
+- Related Schemas:
+  - `SyncLogEntry` — tldw_Server_API/app/api/v1/schemas/sync_server_models.py:18
+  - `ClientChangesPayload` — tldw_Server_API/app/api/v1/schemas/sync_server_models.py:50
+  - `ServerChangesResponse` — tldw_Server_API/app/api/v1/schemas/sync_server_models.py:80
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Sync engine and pipelines.
-- Key Classes/Functions: Entry points and strategies.
-- Dependencies: Internal modules and external systems.
-- Data Models & DB: State and logs via `DB_Management`.
-- Configuration: Env vars and feature flags.
-- Concurrency & Performance: Batching, parallelism, rate limits.
-- Error Handling: Retries, backoff, conflict handling.
-- Security: Permissions and safe operations.
+- Architecture & Data Flow:
+  - Client: Read local `sync_log` after `last_local_log_id_sent`, push to `/send`; then pull from `/get` after `last_server_log_id_processed`; apply in a single transaction; update progress markers.
+  - Server: Validate/auth, apply incoming changes with a single authoritative timestamp for the batch, return deltas excluding entries from the same client (`client_id != requesting_client_id`).
+- Key Classes/Functions:
+  - Client engine and operations — tldw_Server_API/app/core/Sync/Sync_Client.py:37 (ClientSyncEngine), :102 (run_sync_cycle), :131 (_push_local_changes), :184 (_pull_and_apply_remote_changes), :237 (_apply_remote_changes_batch)
+  - Server processor (sync endpoint logic) — tldw_Server_API/app/api/v1/endpoints/sync.py:200 (ServerSyncProcessor), :214 (apply_client_changes_batch)
+  - Endpoints — tldw_Server_API/app/api/v1/endpoints/sync.py:83 (POST /send), :129 (GET /get)
+- Dependencies:
+  - `MediaDatabase` transactions and typed exceptions for conflict/db errors.
+  - Central HTTP server; client uses `requests` (via Sync_Client).
+- Data Models & DB:
+  - `sync_log(change_id, entity, entity_uuid, operation, timestamp, client_id, version, payload)` tracked per‑user DB.
+  - Entities handled include `Media`, `Keywords`, junction `MediaKeywords` with explicit link/unlink paths.
+  - FTS updates are performed explicitly where triggers are disabled (see notes in Issues.md).
+- Configuration:
+  - Client defaults in Sync_Client.py (SERVER_API_URL, CLIENT_ID, STATE_FILE, DATABASE_PATH, SYNC_BATCH_SIZE); recommended to externalize via env or config.
+  - Server mount under `/api/v1/sync` (route policy‑gated in `main.py`).
+- Concurrency & Performance:
+  - Server performs blocking DB ops via `asyncio.to_thread` for predictable behavior; batch all changes in a single transaction.
+  - Client uses transactional apply; idempotent operations to tolerate retries.
+- Error Handling:
+  - Network/HTTP: robust logging; endpoints map to 500/409/4xx; client treats network errors as non‑fatal for pull when push failed.
+  - Conflicts: compare versions/client_id and fall back to LWW on server timestamp; idempotency skips duplicates/older versions.
+- Security:
+  - Endpoints require authenticated user (per‑user DB via `get_media_db_for_user`).
+  - Client TODOs: add auth headers/tokens (see Issues.md recommendations).
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: New sync sources/targets.
-- Coding Patterns: DI, logging, metrics.
-- Tests: Where tests live; fixtures and simulators.
-- Local Dev Tips: Local sync scenarios.
-- Pitfalls & Gotchas: Idempotency, partial failures.
-- Roadmap/TODOs: Improvements and monitoring.
+- Folder Structure:
+  - `Sync_Client.py` — client engine (state file, push/pull/apply).
+  - `Issues.md` — design review and improvement backlog.
+- Extension Points:
+  - Add new entity handlers if schema expands; ensure payload normalization and idempotency for create/update/delete/link/unlink.
+  - Consider adapter for alternative transports (e.g., queued jobs) if needed.
+- Coding Patterns:
+  - Keep SQL minimal and parameterized; use `MediaDatabase.transaction()` for all mutations.
+  - Prefer explicit, defensive payload parsing; maintain version/client_id invariants.
+- Tests:
+  - No dedicated tests yet. Add unit/integration tests under `tldw_Server_API/tests/Sync/` (client state transitions, conflict resolution, endpoint round‑trip with sqlite fixtures).
+- Local Dev Tips:
+  - Start server; configure `SERVER_API_URL`, `CLIENT_ID`, and `DATABASE_PATH` in `Sync_Client.py` (or via env) for quick trials.
+  - Exercise endpoints via `/docs`: POST `/api/v1/sync/send`, GET `/api/v1/sync/get`.
+- Pitfalls & Gotchas:
+  - Ensure `CLIENT_ID` uniqueness per device/instance; state file should be per‑client.
+  - Be mindful of FTS sync ordering when triggers are disabled (delete/update before main; insert after).
+  - Link/unlink operations for junction tables require UUID lookups; skip gracefully if parents don’t exist locally.
+- Roadmap/TODOs:
+  - Implement authenticated client requests; externalize configuration; add end‑to‑end tests and monitoring/metrics for sync volume and latency.

 # Third_Party
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
+Provider adapters for external scholarly/metadata services used by the Paper Search API. Each adapter normalizes provider responses to a common shape and exposes simple search/lookup helpers; endpoints are defined in `paper_search.py` and `research.py`.
 
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: Integrations and bridges to third-party systems.
-- Capabilities: Supported services, adapters, and interoperability.
-- Inputs/Outputs: Requests, callbacks, and artifacts.
-- Related Endpoints: Link API routes and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Unified access to paper/preprint providers (search + DOI/ID lookups) with consistent return signatures and resilient HTTP behavior.
+- Capabilities (adapters):
+  - arXiv: query + XML convert helpers — `Arxiv.py`
+  - BioRxiv/MedRxiv: multiple report feeds, raw passthroughs — `BioRxiv.py`
+  - PubMed + PMC (OAI-PMH, OA service): search and ingest helpers — `PubMed.py`, `PMC_OAI.py`, `PMC_OA.py`
+  - Semantic Scholar: search + details — `Semantic_Scholar.py`
+  - OpenAlex: venue-constrained search + DOI lookup — `OpenAlex.py`
+  - Crossref: DOI search/lookup — `Crossref.py`
+  - IEEE Xplore (keyed): search + DOI/ID lookup — `IEEE_Xplore.py`
+  - Springer Nature (keyed): search + DOI lookup — `Springer_Nature.py`
+  - Elsevier Scopus (keyed): search + DOI lookup — `Elsevier_Scopus.py`
+  - OSF/EarthArXiv, Figshare, Zenodo, IACR, RePEc, Vixra — dedicated adapters following the same pattern.
+- Inputs/Outputs:
+  - Inputs: query strings, pagination/filters, optional provider API keys.
+  - Outputs: lists of normalized paper dicts or single‑record lookups; on error: `(None, ..., error_message)`.
+- Related Endpoints (primary):

 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Adapter patterns and data flow.
-- Key Classes/Functions: Entry points and registries.
-- Dependencies: Internal modules and external SDKs.
-- Data Models & DB: Persisted state via `DB_Management`.
-- Configuration: Env vars, secrets, and config keys.
-- Concurrency & Performance: Batching, caching, rate limits.
-- Error Handling: Retries/backoff; partial failures.
-- Security: Secret handling, permissions, validation.
+- Architecture & Data Flow:
+  - Endpoints (FastAPI) receive validated forms and offload blocking provider calls to a thread pool; adapters use the centralized HTTP client (`core/http_client.py`) with retry/jitter, trust_env=False, and metrics hooks.
+  - Adapters return tuples following convention: for search `(items: Optional[List[dict]], total: int, error: Optional[str])`, for lookups `(record: Optional[dict], error: Optional[str])`.
+- Key Modules/Functions:
+  - arXiv: `search_arxiv_custom_api`, `fetch_arxiv_xml`, `convert_xml_to_markdown` — tldw_Server_API/app/core/Third_Party/Arxiv.py:61, :99, :213
+  - Semantic Scholar: `search_papers_semantic_scholar`, `get_paper_details_semantic_scholar` — tldw_Server_API/app/core/Third_Party/Semantic_Scholar.py:39, :152
+  - OpenAlex: `search_openalex`, `get_openalex_by_doi` — tldw_Server_API/app/core/Third_Party/OpenAlex.py:58, :102
+  - Crossref: `search_crossref`, `get_crossref_by_doi` — tldw_Server_API/app/core/Third_Party/Crossref.py:57, :97
+  - IEEE Xplore: `search_ieee`, `get_ieee_by_doi`, `get_ieee_by_id` — tldw_Server_API/app/core/Third_Party/IEEE_Xplore.py:49, :97, :127
+  - Springer Nature: `search_springer`, `get_springer_by_doi` — tldw_Server_API/app/core/Third_Party/Springer_Nature.py:63, :110
+  - Elsevier Scopus: `search_scopus`, `get_scopus_by_doi` — tldw_Server_API/app/core/Third_Party/Elsevier_Scopus.py:71, :118
+- Dependencies:
+  - Uses `requests` with `HTTPAdapter` retries; tries `httpx` via `core/http_client.create_client` when available.
+  - Optional keys per provider (see Configuration); some offer improved limits when setting contact email (e.g., OpenAlex mailto).
+- Data Models & DB:
+  - Response shapes normalized to “GenericPaper”-like fields: `id`, `title`, `authors`, `journal`, `pub_date`, `abstract`, `doi`, `url`, `pdf_url`, `provider`.
+  - Ingest endpoints optionally persist content to the per‑user Media DB via `MediaDatabase.add_media_with_keywords` (see arXiv/PMC OA ingest paths in `paper_search.py`).
+- Configuration (env vars):
+  - `IEEE_API_KEY` (IEEE Xplore), `SPRINGER_NATURE_API_KEY` (Springer), `ELSEVIER_API_KEY` (+ optional `ELSEVIER_INST_TOKEN`) (Scopus).
+  - `OPENALEX_MAILTO` (recommended to improve reliability/rate limits), `UNPAYWALL_EMAIL` (required for Unpaywall DOI resolution).
+  - HTTP client knobs (optional): `HTTP_CONNECT_TIMEOUT`, `HTTP_READ_TIMEOUT`, `HTTP_RETRY_ATTEMPTS`, etc. (see `core/http_client.py`).
+- Concurrency & Performance:
+  - Endpoints use `run_in_executor` to avoid blocking the event loop; batching handled by providers where supported.
+  - Retries/backoff configured per adapter; endpoints accept OK/timeout/gateway errors to avoid flakiness in CI when providers throttle.
+- Error Handling:
+  - All adapters map network/HTTP errors to informative `error_message` strings; endpoints convert to HTTP 502/504 or 404 when appropriate.
+  - Raw passthrough endpoints (BioRxiv) return provider content and media types directly when requested.
+- Security:
+  - Secrets via env only; headers redacted in logs by the centralized client. Proxies are disabled by default (`trust_env=False`).
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: Adding/maintaining a third-party adapter.
-- Coding Patterns: DI, logging, rate limiting.
-- Tests: Fixtures and mocking external APIs.
-- Local Dev Tips: Test configs and stubs.
-- Pitfalls & Gotchas: Version drift; quotas.
-- Roadmap/TODOs: Planned providers.
+- Folder Structure:
+  - One file per provider under `core/Third_Party/` implementing search/lookup helpers; keep shapes aligned with GenericPaper fields.
+- Extension Points:
+  - New provider adapter should expose `search_(...) -> (items,total,error)` and `get__by_doi(...) -> (record,error)` when applicable.
+  - Normalize outputs to the common fields and use the centralized HTTP client (prefer) or `requests` with retries.
+- Coding Patterns:
+  - Minimal transformation + explicit normalization; no heavy parsing beyond what the provider returns.
+  - Use environment‑gated features (e.g., API keys) and return a helpful error when missing (see IEEE/Springer/Scopus helpers).
+- Tests:
+  - External/integration tests (skipped by default; set `RUN_EXTERNAL_API_TESTS=1` to enable):
+    - tldw_Server_API/tests/PaperSearch/integration/test_paper_search_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_biorxiv_reports_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_figshare_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_earthrxiv_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_vixra_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_iacr_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_medrxiv_external.py:1
+    - tldw_Server_API/tests/PaperSearch/integration/test_zenodo_external.py:1
+  - Missing‑key behavior is validated (returns 501) for IEEE/Springer/Scopus — see test_paper_search_external.py:61, :69, :77.
+- Local Dev Tips:
+  - Start with OpenAlex/Crossref (no keys). Configure optional keys as needed (`IEEE_API_KEY`, `SPRINGER_NATURE_API_KEY`, `ELSEVIER_API_KEY`).
+  - For Unpaywall DOI OA resolution, set `UNPAYWALL_EMAIL`.
+  - Use the `paper_search.py` endpoints for quick manual testing via `/docs`.
+- Pitfalls & Gotchas:
+  - Providers rate‑limit and occasionally time out; endpoints intentionally allow 200/404/502/504 in tests to reduce flakiness.
+  - Some providers don’t return direct `pdf_url` (e.g., Scopus); resolve via Unpaywall when needed.
+  - XML/HTML parsing can be brittle (arXiv/PMC); prefer small, defensive transformations.
+- Roadmap/TODOs:
+  - Expand provider parity (additional OSF preprint servers), add cache hints, and consider adapter‑level metrics (success rate/latency per provider).

 # Usage
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: What Usage tracks/reports and why it exists.
-- Capabilities: Quotas, usage metrics, per-user/provider accounting.
-- Inputs/Outputs: Events/metrics inputs; reports/aggregates outputs.
-- Related Endpoints: Link API routes (if any) and files.
-- Related Schemas: Pydantic models used.
+- Purpose: Track usage and quotas for selected modules (e.g., audio) and support pricing catalogs.
+- Capabilities:
+  - Per-user usage counters; simple quota checks for audio
+  - Pricing catalog utilities for cost estimation
+- Inputs/Outputs:
+  - Inputs: usage events (audio seconds, requests)
+  - Outputs: counters and quota decisions
+- Related Modules:
+  - `tldw_Server_API/app/core/Usage/audio_quota.py:1`, `pricing_catalog.py:1`, `usage_tracker.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Producers/consumers and data flow.
-- Key Classes/Functions: Entry points to usage accounting.
-- Dependencies: Internal modules and external metrics backends.
-- Data Models & DB: Tables/indices via `DB_Management`.
-- Configuration: Env vars, rate limits, feature flags.
-- Concurrency & Performance: Batching, aggregation, retention.
-- Error Handling: Backoff/retry, partial failures.
-- Security: Privacy and access control.
+- Architecture & Data Flow:
+  - Utilities consumed by endpoints/services to increment counters and enforce quotas
+- Key Classes/Functions:
+  - `audio_quota`: quota checks and updates
+  - `pricing_catalog`: catalog lookups for provider/model pricing
+  - `usage_tracker`: simple in-memory/file-backed patterns
+- Dependencies:
+  - Internal: Metrics module for counters (if configured)
+- Data Models & DB:
+  - No dedicated DB by default; pluggable backends as needed
+- Configuration:
+  - Provider pricing via config/env; limits via env
+- Concurrency & Performance:
+  - Lightweight, called in hot paths (keep O(1))
+- Error Handling:
+  - Fail-safe decisions when catalog missing; log warnings
+- Security:
+  - Enforce per-user scope
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: New usage counters or sinks.
-- Coding Patterns: DI, logging, rate limiting.
-- Tests: Where tests live; fixtures.
-- Local Dev Tips: Sample events and queries.
-- Pitfalls & Gotchas: High-cardinality and retention choices.
-- Roadmap/TODOs: Improvements and migration notes.
-
+- Folder Structure:
+  - `Usage/` with `audio_quota.py`, `pricing_catalog.py`, `usage_tracker.py`
+- Extension Points:
+  - Add new sinks (DB/prometheus) and resources; wire into endpoints
+- Coding Patterns:
+  - Keep counters consistent with Metrics; minimize global state
+- Tests:
+  - (Add module-level tests as behaviors expand)
+- Local Dev Tips:
+  - Start with generous limits to avoid noisy tests; enable metrics to observe counters
+- Pitfalls & Gotchas:
+  - High-cardinality labels if exported to metrics; cap keys
+- Roadmap/TODOs:
+  - Persistent usage store; richer pricing per tier

 # Utils
 
-Note: This README is scaffolded from the core template. Replace placeholders with accurate details.
-
 ## 1. Descriptive of Current Feature Set
 
-- Purpose: What Utils provides and why it exists.
-- Capabilities: Common helpers and utilities.
-- Inputs/Outputs: Typical inputs/outputs of key helpers.
-- Related Endpoints: Link API routes (if any) and files.
-- Related Schemas: Pydantic models (if applicable).
+- Purpose: Common helpers used across modules (tokenization, image validation, prompt loading, system checks, etc.).
+- Capabilities:
+  - Tokenizer helpers, chunked image processing, CPU-bound execution wrappers
+  - Prompt loader for multi-namespace prompts, pydantic compatibility helpers
+  - Metadata utilities and system checks
+- Inputs/Outputs:
+  - Inputs: strings/blobs/paths; Outputs: derived strings/structures/booleans
+- Related Modules:
+  - `tldw_Server_API/app/core/Utils/Utils.py:1`, `tokenizer.py:1`, `prompt_loader.py:1`, `image_validation.py:1`, `System_Checks_Lib.py:1`
 
 ## 2. Technical Details of Features
 
-- Architecture & Data Flow: Groupings and boundaries of utilities.
-- Key Classes/Functions: Entry points and widely used helpers.
-- Dependencies: Internal/external dependencies.
-- Data Models & DB: Any DB touchpoints.
-- Configuration: Env vars and config keys.
-- Concurrency & Performance: Async/threading, memoization, caching.
-- Error Handling: Exceptions and common failure modes.
-- Security: Input validation and safe defaults.
+- Architecture & Data Flow:
+  - Self-contained modules; no cross-layer coupling; safe to import from endpoints and services
+- Key Helpers:
+  - `tokenizer`, `chunked_image_processor`, `executor_registry`, `cpu_bound_handler`, `prompt_loader`
+- Dependencies:
+  - Standard library and lightweight third-parties only
+- Data Models & DB:
+  - None
+- Configuration:
+  - Minimal; helpers read env only if necessary
+- Concurrency & Performance:
+  - CPU-bound helpers offload to thread/process pools where needed
+- Error Handling:
+  - Fail safe semantics; return empty defaults when appropriate
+- Security:
+  - Validate inputs; avoid touching filesystem unless explicit
 
 ## 3. Developer-Related/Relevant Information for Contributors
 
-- Folder Structure: Subpackages and responsibilities.
-- Extension Points: How to add utilities; naming and testing.
-- Coding Patterns: DI, logging, rate limiting.
-- Tests: Where tests live; fixtures and examples.
-- Local Dev Tips: Examples and usage snippets.
-- Pitfalls & Gotchas: Avoid footguns; backward compatibility.
-- Roadmap/TODOs: Future refactors or consolidation.
-
+- Folder Structure:
+  - Individual helper modules under `Utils/`
+- Extension Points:
+  - Add new helpers where reuse is expected; keep SRP
+- Coding Patterns:
+  - Small, well-tested functions; loguru for diagnostics only when helpful
+- Tests:
+  - (Add targeted unit tests for new helpers)
+- Local Dev Tips:
+  - Import helpers directly in endpoints/services; avoid circular deps
+- Pitfalls & Gotchas:
+  - Do not add heavy deps here; keep import-time light
+- Roadmap/TODOs:
+  - Consolidate overlapping helpers; add type hints where missing

+# Embeddings Adapter Scaffold (Stage 4)
+
+This document tracks the initial scaffold for migrating embeddings to the provider adapter architecture.
+
+What’s included
+- `EmbeddingsProvider` interface in `tldw_Server_API/app/core/LLM_Calls/providers/base.py`.
+- Embeddings adapter registry in `tldw_Server_API/app/core/LLM_Calls/embeddings_adapter_registry.py`.
+- OpenAI embeddings adapter (delegate-first) in `tldw_Server_API/app/core/LLM_Calls/providers/openai_embeddings_adapter.py`.
+
+Behavior
+- By default, the OpenAI embeddings adapter delegates to the existing legacy helper `get_openai_embeddings()` for parity and to avoid network during tests.
+- Native HTTP can be enabled with `LLM_EMBEDDINGS_NATIVE_HTTP_OPENAI=1` (uses `httpx` at `OPENAI_BASE_URL` or default OpenAI URL).
+
+Next steps
+- Add generic OpenAI-compatible embeddings adapter (local servers) mirroring chat adapters.
+- Wire a shim for embeddings to allow endpoint opt-in via env flag without touching the production embeddings service.
+- Extend registry defaults as more embeddings providers are adapted.
+- Conformance tests: shape of responses, error mapping, batch behavior, and performance smoke.
+

 Phase 4: Embeddings (optional follow-up)
 - Consider moving embeddings to provider adapters (or parallel `EmbeddingsProvider`) while preserving current endpoints.
 
+Status (initiated)
+- Added `EmbeddingsProvider` interface, registry, and an OpenAI embeddings adapter (delegate-first).
+- Native HTTP is opt-in via `LLM_EMBEDDINGS_NATIVE_HTTP_OPENAI`.
+- Endpoint wiring remains unchanged; migration will be opt-in via shim in a subsequent PR.
+
 ## 11. Backward Compatibility
 - Public FastAPI endpoints unchanged; request/response schema remains OpenAI-compatible.
 - Legacy `provider_config.API_CALL_HANDLERS` continue to exist, delegating to the registry, so orchestrators and tests remain intact.

+WebUI CSP (Content Security Policy)
+- `TLDW_WEBUI_NO_EVAL`: When set, controls whether `'unsafe-eval'` is allowed for `/webui` scripts.
+  - Precedence: if present, its truthiness decides the policy; otherwise a production-aware default applies.
+  - Truthy values (case-insensitive): `1`, `true`, `yes`, `on`, `y` → DISABLE eval (no `'unsafe-eval'`).
+  - Falsy values (e.g., `0`, `false`) → ENABLE eval.
+  - If unset: default is `False` (no eval) in production (`ENVIRONMENT|APP_ENV|ENV in {prod, production}`), and `True` (allow eval) in non-production.
+
 ## AuthNZ (Authentication)
 - `AUTH_MODE`: `single_user` | `multi_user`.
 - `DATABASE_URL`: AuthNZ database URL. For production multi-user, use Postgres.

+- Policy route_map precedence:
+  - When `RG_POLICY_STORE=db` is in use, policies (limits) load from the DB store but `route_map` is currently sourced from the YAML file and merged into the snapshot. If both DB and file provide mappings in the future, file route_map takes precedence unless otherwise documented.

  - `RG_ENABLE_SIMPLE_MIDDLEWARE`: `true|false` to enable the minimal pre-check middleware for `requests` category using route tags/path mapping.
 
+#### Simple Middleware (opt‑in)
+- Resolution order: path-based mapping (`route_map.by_path`) first, then tag-based mapping (`route_map.by_tag`). Wildcards like `/api/v1/chat/*` match by prefix.
+- Entity derivation: prefers authenticated user (`user:{id}`), then API key id/hash (`api_key:{id|hash}`), then trusted proxy IP header via `RG_CLIENT_IP_HEADER` when `RG_TRUSTED_PROXIES` contains the peer; otherwise falls back to `request.client.host`.
+- Behavior: performs a pre-check/reserve for the `requests` category before calling the endpoint and commits afterwards. On denial, sets `Retry-After` and `X-RateLimit-*` headers. On success, injects accurate `X-RateLimit-*` headers using a governor `peek` when available.
+- Enable by setting `RG_ENABLE_SIMPLE_MIDDLEWARE=true`. It only guards `requests` in this minimal form; streaming/tokens categories require explicit endpoint plumbing for reserve/commit.

 ### OpenAI-Compatible Strict Mode (Local Providers)
 
 Some self-hosted OpenAI-compatible servers reject unknown fields (like `top_k`). For local providers you can enable a strict mode that filters non-standard keys from chat payloads.

+## Egress Policy and DNS Pinning
+
+Some deployments enforce an egress allowlist for sandboxed runs. The Docker runner supports a deny‑all baseline (network=none) and, when enabled, a granular host‑level allowlist using iptables on the DOCKER-USER chain.
+
+Utilities exposed in `tldw_Server_API.app.core.Sandbox.network_policy` help you prepare and manage rules:
+
+- `expand_allowlist_to_targets(raw_allowlist, resolver=..., wildcard_subdomains=("", "www", "api"))`
+  - Accepts a mix of CIDR (e.g., `10.0.0.0/8`), literal IPs (`8.8.8.8`), hostnames (`example.com`), wildcard prefixes (`*.example.com`), and suffix tokens (`.example.com`).
+  - Resolves hostnames to A records and promotes to `/32`; returns a de‑duplicated list like `['1.2.3.4/32', '10.0.0.0/8']`.
+
+- `pin_dns_map(raw_allowlist, resolver=...)`
+  - Returns a mapping `{ host -> [IPs] }` after resolution for observability/debugging.
+
+- `refresh_egress_rules(container_ip, raw_allowlist, label, resolver=..., wildcard_subdomains=...)`
+  - Best‑effort revocation + re‑apply: deletes all rules in DOCKER‑USER containing `label` and applies an updated set of `ACCEPT` rules for resolved targets, followed by a final `DROP` for the container IP.
+
+Examples:
+```
+from tldw_Server_API.app.core.Sandbox.network_policy import (
+    expand_allowlist_to_targets, pin_dns_map, refresh_egress_rules
+)
+
+# Allowlist with CIDR, IP, wildcard and suffix tokens
+raw = ["10.0.0.0/8", "8.8.8.8", "*.example.com", ".example.org"]
+targets = expand_allowlist_to_targets(raw)
+# e.g., ['10.0.0.0/8', '8.8.8.8/32', '93.184.216.34/32', ...]
+
+# Inspect pinned DNS map (for logs/metrics)
+pins = pin_dns_map(raw)
+# e.g., {'example.com': ['93.184.216.34', ...], 'example.org': ['203.0.113.10', ...]}
+
+# Apply (or refresh) rules for a given container
+apply_specs = refresh_egress_rules(
+    container_ip="172.18.0.2",
+    raw_allowlist=raw,
+    label="tldw-run-",
+)
+```
+
+Notes:
+- Suffix tokens (like `.example.com`) behave like wildcards for a few common subdomains plus the apex (configurable).
+- If `iptables-restore` is unavailable, the code falls back to iterative `iptables` commands.
+- To revoke rules for a finished container, the runner labels and deletes rules by that label.
+
 ## Notes
 - Spec versions are validated against server config. Default: `["1.0","1.1"]`.
 - Interactivity requires runtime and policy support; fields are ignored otherwise.
 - `log_stream_url` may be unsigned; prefer Authorization headers if signed URLs are disabled.

+### Acceptance‑Window Fallback (Requests)
+
+Real Redis can occasionally report window counts near boundaries that admit a request even when a prior denial suggested a small retry_after. To keep behavior deterministic (especially in CI), the Redis backend maintains a per‑(policy, entity) “acceptance‑window” tracker for requests:
+
+- When the tracker observes that `limit` requests were accepted within the current window, further requests are denied until the window end (floor). This is an additive guard over ZSET counts, not a replacement.
+- On denial, the guard sets a deny‑until floor to the end of the window to avoid early admits caused by rounding/drift.
+- In test contexts, you can prefer the acceptance‑window path by setting `RG_TEST_FORCE_STUB_RATE=1`.
+
+### Policy Composition & Retry‑After
+
+- Composition (strictest wins): for each category, compute headroom per applicable scope (global, tenant, user, conversation); the effective headroom is the minimum across scopes.
+- Deny when effective headroom < requested units.
+- Retry‑After aggregation: per category, compute the maximum retry_after across denying scopes; the overall decision retry_after is the maximum across denied categories. This prevents premature retries when multiple scopes deny with different windows.
+
+### Metrics Labels & Cardinality
+
+- Counters/gauges:
+  - `rg_decisions_total{category,scope,backend,result,policy_id}`

+## 11. Implementation Plan (Staged)
+
+Stage 1: Abstractions & Baseline (Complete)
+- Goal: Implement `AsyncStream`, `SSEStream`, `WebSocketStream` with base metrics and tests.
+- Success: One Chat SSE path migrated; DONE/error/heartbeat semantics verified with unit tests.
+
+Stage 2: Pass‑through + Timeouts (Complete)
+- Goal: Provider control pass‑through, SSE idle/max enforcement, close‑code guidance.
+- Success: Normalization toggles in place; SSE idle/max tested; metrics labels available.
+
+Stage 3: Pilot Rollout (In Progress)
+- Goal: Adopt under `STREAMS_UNIFIED` for key endpoints; validate with WebUI and two providers.
+- Current pilots:
+  - Chat SSE: Character chat, main chat completions, document‑generation.
+  - Embeddings SSE orchestrator.
+  - Evaluations SSE (A/B tests and batch emitters).
+  - Jobs Admin SSE (events outbox, retains `id:` pass‑through).
+  - Prompt Studio SSE fallback (when flag enabled).
+  - Audio WS and MCP WS using `WebSocketStream` (JSON‑RPC preserved for MCP; compat `error_type` shims).
+- Remaining work for Stage 3:
+  - Non‑prod validation with WebUI across two providers; ensure no duplicate `[DONE]` and heartbeats visible.
+  - Expand unit/integration tests for backpressure and long‑running sessions (SSE heartbeats not starved; WS idle close behavior).
+  - Add/verify provider control pass‑through at call sites that depend on `event:`/`id:`.
+
+Stage 4: Broader Adoption (Planned)
+- Goal: Migrate any remaining bespoke streaming code paths, preserve domain payloads, and standardize lifecycle.
+- Targets to confirm/migrate:
+  - Any residual Chat/Character local SSE helpers (delete after flip).
+  - Embeddings orchestrator legacy code path (remove once default flips).
+  - Jobs PG outbox test hardening and re‑enablement.
+
+Stage 5: Cleanup & Default Flip (Planned)
+- Goal: Remove legacy helpers, flip `STREAMS_UNIFIED` default on in non‑prod → prod.
+- Rollback: Toggle `STREAMS_UNIFIED=0` to revert to legacy per‑endpoint implementations.
+
+Test Matrix (High‑level)
+- SSE
+  - Chat (character, completions, doc‑gen): DONE dedup, errors, heartbeats, backpressure.
+  - Embeddings orchestrator: `event: summary`, heartbeats, idle/max.
+  - Evaluations: event cadence, DONE.
+  - Jobs Admin: `id:` pass‑through, paging, SSE stream.
+  - Prompt Studio fallback: DONE and heartbeat parity.
+- WebSocket
+  - Audio: ping, compat `error_type`, quota → 1008, internal → 1011.
+  - MCP: ping/idle close, JSON‑RPC parse errors, no event‑frame wrapping.
+- Flags
+  - `STREAMS_UNIFIED` on/off parity; `STREAM_PROVIDER_CONTROL_PASSTHRU` per‑endpoint overrides.
+
+Rollback Notes
+- Primary rollback is configuration only: set `STREAMS_UNIFIED=0` to restore legacy paths.
+- Keep compat shims (`error_type`) until all clients migrate to `code`+`message`.
+- If SSE buffering observed under proxies, prefer `heartbeat_mode=data` and verify `X‑Accel‑Buffering: no` in ingress.

+### Validation Checklist (non‑prod)
+
+Environment
+- Use dev/staging with unified streams enabled:
+  - Compose overlay: `-f Dockerfiles/docker-compose.yml -f Dockerfiles/Dockerfiles/docker-compose.dev.yml`
+  - or export `STREAMS_UNIFIED=1` in the environment prior to starting the API.
+- Ensure provider keys are set for at least two providers (e.g., OpenAI and Groq).
+- Optional: behind reverse proxies/CDNs, set `STREAM_HEARTBEAT_MODE=data`.
+
+Functional
+- Chat SSE (main): stream completion; assert only one `data: [DONE]` and proper OpenAI deltas.
+- Character chat SSE: stream conversation; validate heartbeat presence during idle and single `DONE`.
+- Chat document-generation SSE: stream doc; validate heartbeat and final `DONE` without duplicates.
+- Embeddings orchestrator SSE (if used): confirm `event: summary` frames appear periodically.
+- Prompt Studio SSE fallback (if used): connect and observe initial state + heartbeats.
+
+WebSockets
+- Audio WS: open a session; observe `{type:"ping"}` frames; trigger an error path and confirm error frame + close code mapping.
+- MCP WS: open a session; confirm lifecycle frames (`ping`, `done` when closed) and that JSON‑RPC responses are unchanged.
+
+Metrics & Dashboards
+- Import `Docs/Deployment/Monitoring/Grafana_Streaming_Basics.json`.
+- Confirm:
+  - `sse_enqueue_to_yield_ms` histogram shows activity during SSE streams.
+  - `sse_queue_high_watermark` increases during bursts.
+  - `ws_send_latency_ms` histogram increments on WS sends.
+  - `ws_pings_total` increments for WS endpoints; `ws_ping_failures_total` remains 0.
+
+Rollback
+- Toggle `STREAMS_UNIFIED=0` and restart app to revert to legacy streaming.

 - Success: No client changes required; metrics visible in dashboard.
 
 Stage 5 — Audio WS Standardization
+- Status: Complete
 - Goal: Adopt `WebSocketStream` for lifecycle (ping, error, done) without changing domain payloads.
 - Code:
-  - Wrap handler to use `WebSocketStream(..., compat_error_type=True)` during rollout.
-  - Standardize idle timeout close (1001); ping loop uses abstraction; retain domain messages.
+  - Unified handler uses `WebSocketStream(..., compat_error_type=True)` and labels `{component: audio, endpoint: audio_unified_ws}`.
+  - Standardized error/done semantics; retained legacy quota close (4003) and `error_type` for client compatibility.
+  - Routed status/summary frames via `stream.send_json` for metrics coverage; domain payloads unchanged.
 - Tests:
-  - Ping schedule, idle timeout counter increments, error/done frames, backwards-compatible error fields.
+  - Quota/concurrency WS tests pass; streaming unit tests cover WS metrics and error/done; additional ping/idle tests can be added if needed.
 - Success: Clients unaffected; improved observability in streaming dashboard.
 
 Stage 6 — MCP WS Lifecycle Adoption
+- Status: Complete
 - Goal: Use `WebSocketStream` for ping/idle/error; never wrap JSON‑RPC content or emit `done` as JSON‑RPC.
 - Code:
-  - Integrate ping loop and standardized error close mapping; keep JSON‑RPC untouched.
+  - MCP server uses `WebSocketStream` with labels `{component: mcp, endpoint: mcp_ws}`; origin/IP/auth guards in place.
+  - Standardized close-code mapping; JSON‑RPC payloads unchanged; lifecycle metrics emitted.
 - Tests:
-  - Ping behavior, idle timeout (1001), errors with `code` and (`error_type` during rollout if needed).
+  - Full MCP WS/HTTP test suite passes (JSON-RPC, security, rate limits, etc.).
+  - Unified WS lifecycle verified by tests; metrics available for dashboards.
 - Success: MCP dashboard unchanged for content; lifecycle metrics added.
 
 Stage 7 — Cleanup, Docs, and Flip Default
-- Goal: Remove endpoint-local helpers, update docs, and flip `STREAMS_UNIFIED` default.
-- Code:
-  - Delete duplicative SSE helpers; unify DONE suppression.
-  - Flip feature flag default to ON after one release; guard with rollback instructions.

+## Compatibility Follow-ups
+
+Audio WS legacy quota close code
+- Current behavior: For client compatibility, the Audio WS handler emits an `error` frame with `error_type: "quota_exceeded"` and closes with code `4003` when quotas are exceeded.
+- Target behavior: Migrate to standardized close code `1008` (Policy Violation) with structured `{type: "error", code: "quota_exceeded", message, data?}` and without the legacy `error_type` field once downstream clients have updated.
+- Migration plan:
+  - Phase 1 (current): Keep `4003` and include `error_type` alias (compat_error_type=True) in `WebSocketStream` for Audio. Documented in API/SDK release notes.
+  - Phase 2 (flagged pilot): Expose an opt‑in environment toggle (ops only) to switch close code to `1008` while still including `error_type` for a release.
+  - Phase 3 (default switch): Change default to `1008` and keep `error_type` for one additional release.
+  - Phase 4 (cleanup): Remove `error_type` alias for Audio WS and rely solely on `code` + `message`.
+  - Acceptance: No client breakages reported in non‑prod → prod flips; tests updated to assert `1008`.
+
+Endpoint audit and duplicate closes
+- WebSockets
+  - Workflows WS, Sandbox WS, Prompt Studio WS, MCP Unified WS, and Persona WS are wrapped with `WebSocketStream` and emit standardized lifecycle metrics/frames. Domain payloads remain untouched where required.
+  - Audio WS: outer endpoint still performs some direct `send_json/close` for auth/quota compatibility; the inner unified handler uses `WebSocketStream`. Double‑close risks are minimized (idempotent close), but a follow‑up refactor will consolidate closing into the unified layer after the quota close migration (above) to simplify logic.
+  - Parakeet Core demo WS (`/core/parakeet/stream`) is a portable minimal router not mounted in the main app; it intentionally does not use `WebSocketStream` (kept as a standalone sample core).
+- SSE
+  - Chat: pilot paths (character chat, chat completions, document‑generation) are unified behind `STREAMS_UNIFIED`.
+  - Embeddings orchestrator: unified to `SSEStream` behind `STREAMS_UNIFIED` while preserving `event: summary`.
+  - Evaluations SSE (`evaluations_unified.py`) currently uses a bespoke `StreamingResponse` generator; a low‑risk follow‑up item will migrate it to `SSEStream` to standardize heartbeats/metrics.
+
+Monitoring/dashboard validation
+- Import `Docs/Deployment/Monitoring/Grafana_Streaming_Basics.json` in Grafana (Prometheus datasource UID `prometheus`).
+- Confirm Persona WS series appear with labels `{component: persona, endpoint: persona_ws, transport: ws}` in the WS panels.

+# Tracking Issue — STREAMS_UNIFIED Flip (Dev → Staging → Prod)
+
+Status: Open
+Owner: Streaming/Platform
+Created: 2025-11-04
+
+Goal
+- Validate unified SSE/WS streams behind `STREAMS_UNIFIED` and flip the flag ON in staging, then plan production.
+
+References
+- PRD: `Docs/Design/Stream_Abstraction_PRD.md` (Status: Pilot Rollout)
+- Dev Overlay: `Dockerfiles/Dockerfiles/docker-compose.dev.yml`
+- Metrics Dashboard: `Docs/Deployment/Monitoring/Grafana_Streaming_Basics.json`
+
+Checklist
+
+Phase A — Dev validation
+- [ ] Start API with dev overlay or `STREAMS_UNIFIED=1` env
+- [ ] Configure two providers (e.g., OpenAI + Groq)
+- [ ] Chat SSE (main): single `[DONE]`, OpenAI deltas present
+- [ ] Character chat SSE: heartbeat under idle; single `[DONE]`
+- [ ] Chat document-generation SSE: heartbeat; no duplicate `[DONE]`
+- [ ] Embeddings orchestrator SSE: `event: summary` frames periodic
+- [ ] Prompt Studio SSE fallback: initial state + heartbeats
+- [ ] Audio WS: pings observed; quota or validation error emits error frame and closes with correct code
+- [ ] MCP WS: JSON-RPC responses unchanged; lifecycle frames present; idle close works
+- [ ] Metrics present: `sse_enqueue_to_yield_ms`, `sse_queue_high_watermark`, `ws_send_latency_ms`, `ws_pings_total`
+
+Phase B — Staging flip
+- [ ] Enable `STREAMS_UNIFIED=1` in staging
+- [ ] Import Grafana dashboard and confirm labels for key endpoints
+- [ ] Soak for 48h; watch idle timeouts and ping failures
+- [ ] Document any client compatibility issues (Audio `error_type` alias still on)
+- [ ] If regressions: toggle back to `STREAMS_UNIFIED=0` (rollback) and file follow-ups
+
+Phase C — Production plan
+- [ ] Announce window; confirm client compatibility (Audio/MCP consumers)
+- [ ] Flip `STREAMS_UNIFIED=1` progressively (canary)
+- [ ] Verify metrics; no duplicate `[DONE]`; latency within ±1% server-side target
+- [ ] Keep rollback knob in runbook
+
+Notes
+- Prefer `STREAM_HEARTBEAT_MODE=data` behind reverse proxies/CDNs.
+- For provider control lines (`event/id/retry`), keep `STREAM_PROVIDER_CONTROL_PASSTHRU=0` unless a specific integration requires it.

+Circuit Breaker Unification PRD
+
+  - Title: Circuit Breaker Unification
+  - Author: [your name]
+  - Status: Draft
+  - Owners: Core (Infrastructure), Embeddings, Evaluations, RAG, MCP
+  - Related Code: tldw_Server_API/app/core/Embeddings/circuit_breaker.py:1, tldw_Server_API/app/core/Evaluations/circuit_breaker.py:1, tldw_Server_API/app/core/RAG/rag_service/unified_pipeline.py:505,

+
+  Overview
+
+  - Problem: Multiple, duplicative circuit breaker (CB) implementations diverge in behavior and metrics, increasing maintenance risk.
+  - Unifying Principle: All are the same CircuitBreaker with different labels.
+  - Goal: One unified CB in Infrastructure with per-category config, consistent metrics, and sync/async decorators. Modules inject names/labels only.
+
+  Problem Statement
+
+  - Duplicates and drift:
+      - Embeddings CB with Prometheus metrics: tldw_Server_API/app/core/Embeddings/circuit_breaker.py:1
+      - Evaluations CB with async locks, timeouts, and per-provider configs: tldw_Server_API/app/core/Evaluations/circuit_breaker.py:1
+      - RAG resilience’s own CB and coordinator: tldw_Server_API/app/core/RAG/rag_service/unified_pipeline.py:505, tldw_Server_API/app/core/RAG/rag_service/resilience.py:1
+      - MCP base embeds CB/backoff semantics: tldw_Server_API/app/core/MCP_unified/modules/base.py:242
+      - Additional duplication (noted): Chat provider CB: tldw_Server_API/app/core/Chat/provider_manager.py:1
+  - Symptoms: Inconsistent states, thresholds, timeouts, backoff, and metrics across domains; redundant tests and config.
+
+  Goals
+
+  - Single CB implementation under Infrastructure used by Embeddings, Evaluations, RAG, MCP (and optionally Chat).
+  - Consistent behavior: CLOSED/OPEN/HALF_OPEN, failure thresholds, half-open probe limits, recovery timeouts.
+  - Optional modes: count threshold and rolling-window failure-rate (RAG).
+  - First-class async/sync usage with decorators and call wrappers (with optional per-call timeout).
+  - Unified metrics (Prometheus) with consistent labels: category, service/name, operation/outcome.
+  - Backward-compatible shims and non-breaking migration of tests/config.
+
+  Non-Goals
+
+  - Rewriting retry/fallback/health-monitor logic (keep in their modules; integrate only via consistent CB hooks).
+  - Overhauling provider selection logic or load balancing.
+  - Adding new external dependencies.
+
+  Users And Stakeholders
+
+  - Embeddings team (provider reliability, metrics).
+  - Evaluations/LLM Calls (per-provider CB configs, timeouts).
+  - RAG (resilience coordinator; rolling-window option).
+  - MCP Unified (module backoff semantics, concurrency guard).
+  - Observability/Infra (unified metrics).
+
+  In Scope
+
+  - New tldw_Server_API/app/core/Infrastructure/circuit_breaker.py.
+  - Config unification and adapter: Embeddings, Evaluations, RAG, MCP (and optional Chat).
+  - Metrics standardization and registry.
+  - Back-compat shims in legacy module paths.
+  - Tests and docs updates.
+
+  Out Of Scope
+
+  - Changing existing retry/fallback APIs and semantics.
+  - Replacing health-monitoring subsystems.
+
+  Functional Requirements
+
+  - Provide CircuitBreaker with:
+      - States: CLOSED, OPEN, HALF_OPEN with success threshold and half-open max concurrent probes.
+      - Failure policy: count threshold and optional rolling window (size + failure_rate_threshold).
+      - Recovery policy: recovery timeout with optional exponential backoff (factor, max_timeout).
+      - Error classification: expected_exceptions (count toward CB), unexpected errors pass through.
+      - Optional per-call timeout enforcement for both sync/async calls.
+  - Provide CircuitBreakerConfig with superset of fields:
+      - failure_threshold, success_threshold, recovery_timeout, half_open_max_calls, expected_exceptions, timeout_seconds (per-call), window_size, failure_rate_threshold, backoff_factor, max_recovery_timeout.
+  - Provide simple APIs:
+      - call(func, *args, **kwargs) and call_async(func, *args, **kwargs).
+      - Decorator @circuit_breaker(name=..., category=..., config=...) auto-detects sync/async.
+      - Registry: get_or_create(name, category, config_overrides); status(); reset().
+  - Metrics:
+      - Prometheus counters/gauges: state, trips, failures, successes, rejections, timeouts.
+      - Labels: category, service (name), operation (optional).
+      - Safe re-registration across processes/tests.
+
+  Non-Functional Requirements
+
+  - Thread/async safety: locks around state transitions; no deadlocks; low contention.
+  - Performance: O(1) hot-path operations; rolling-window operations amortized.
+  - Observability: metrics exposed; structured state in get_status().
+  - Compatibility: no breaking changes to public endpoints; shims for legacy imports.
+  - Testing: >80% coverage for new module; integration tests continue to pass.
+
+  Design Overview
+
+  - File: tldw_Server_API/app/core/Infrastructure/circuit_breaker.py
+  - Core types:
+      - CircuitState (Enum)
+      - CircuitBreakerConfig (dataclass)
+      - CircuitBreaker (class) with state machine and optional rolling-window and backoff.
+      - CircuitBreakerRegistry with thread-safe access.
+      - Decorator factory circuit_breaker(...) (sync/async support).
+  - Configuration resolution:
+      - Accept explicit config from call site; otherwise resolve via per-category sources:
+          - Embeddings: tldw_Server_API/Config_Files/embeddings_production_config.yaml (circuit_breaker block)
+          - Evaluations: tldw_Server_API/Config_Files/evaluations_config.yaml (circuit_breakers.providers)
+          - MCP: tldw_Server_API/Config_Files/mcp_modules.yaml (circuit_breaker_* keys)
+          - RAG: defaults from RAG resilience, mapped to unified config
+      - Override order: kwargs > env vars > category config > sensible defaults.
+      - Key mapping table:
+          - circuit_breaker_threshold -> failure_threshold
+          - circuit_breaker_timeout -> recovery_timeout
+          - circuit_breaker_backoff_factor -> backoff_factor
+          - circuit_breaker_max_timeout -> max_recovery_timeout
+          - half_open_requests -> half_open_max_calls
+          - timeout/timeout_seconds -> timeout_seconds
+  - Metrics:
+      - Gauges: circuit_breaker_state{category,service} (0=closed,1=open,2=half_open)
+      - Counters: circuit_breaker_trips_total, circuit_breaker_failures_total, circuit_breaker_successes_total, circuit_breaker_rejections_total, circuit_breaker_timeouts_total
+  - Backward compatibility:
+      - Keep modules exporting shims that import the Infrastructure CB and emit a deprecation warning:
+          - tldw_Server_API/app/core/Embeddings/circuit_breaker.py
+          - tldw_Server_API/app/core/Evaluations/circuit_breaker.py
+          - tldw_Server_API/app/core/RAG/rag_service/resilience.py (CB only; keep retry/fallback/health)
+          - tldw_Server_API/app/core/Chat/provider_manager.py (optional shim or direct call migration)
+      - Replace MCP base’s inline logic with unified CB calls; keep its semaphore guard local.
+
+  API Sketch
+
+  - CircuitBreakerConfig(...)
+  - CircuitBreaker(name, category, config)
+      - await call_async(func, *args, **kwargs)
+      - call(func, *args, **kwargs)
+      - get_status() -> Dict[str, Any]
+      - reset()
+  - get_or_create_breaker(name, category, config_overrides=None)
+  - @circuit_breaker(name, category, config_overrides=None)
+
+  Module Integration Plan
+
+  - Embeddings: Replace direct CircuitBreaker usage with Infrastructure CB; map config; keep Prometheus metrics through unified hooks. Update tests that import tldw_Server_API.app.core.Embeddings.circuit_breaker
+    to work via shim.
+  - Evaluations: Replace LLMCircuitBreaker with per-provider get_or_create_breaker(name=f"llm:{provider}", category="evaluations"); keep timeouts via per-call timeout_seconds. Preserve closed-state concurrency
+    semaphore out of CB if truly needed, or enable opt-in through config.
+  - RAG: Update unified_pipeline.py:505 and resilience.py to use Infrastructure CB; keep RetryPolicy/FallbackChain/HealthMonitor as-is.
+  - MCP: Replace base’s internal CB counters with Infrastructure CB; map backoff fields; keep module semaphore; preserve metrics via unified labels category="mcp".
+  - Chat (optional): Replace provider_manager.CircuitBreaker with unified CB or shim.
+
+  Migration And Deletions
+
+  - Deletions after migration (or convert to shims for 1 release):
+      - tldw_Server_API/app/core/Embeddings/circuit_breaker.py
+      - tldw_Server_API/app/core/Evaluations/circuit_breaker.py
+      - CB portions of tldw_Server_API/app/core/RAG/rag_service/resilience.py
+      - Inline CB logic in tldw_Server_API/app/core/MCP_unified/modules/base.py
+      - Optional: CB in tldw_Server_API/app/core/Chat/provider_manager.py
+  - Update config docs and examples to reference unified fields and mappings.
+
+  Testing
+
+  - Unit tests (new):
+      - State transitions: thresholds, half-open probes, reset.
+      - Rolling-window failure rate mode (RAG parity).
+      - Backoff open-window growth and cap (MCP parity).
+      - Timeout handling (Evaluations parity) for sync/async.
+      - Metrics: state transitions increment expected counters/gauges.
+      - Registry: idempotent get_or_create, concurrent access safety.
+  - Integration tests (existing):
+      - Embeddings production and unit test paths must pass unchanged (import via shim).
+      - Evaluations unified tests must pass; provider configs honored.
+      - RAG unified pipeline resiliency path preserved.
+      - MCP module operations respect open/half-open and backoff.
+
+  Risks And Mitigations
+
+  - Behavior drift due to policy differences (count vs window): expose both modes; default per-category to match prior behavior; add explicit mappings.
+  - Metric cardinality growth (labels): constrain label set to category, service, optional operation.
+  - Backoff interaction with timeouts: document mapping and defaults; add tests mirroring MCP behavior.
+  - Concurrency limits baked into CB: keep concurrency guards outside CB unless explicitly configured.
+
+  Rollout Plan
+
+  - Phase 1: Implement Infrastructure CB + metrics + registry; add adapters/shims; land tests and docs; no module behavior change.
+  - Phase 2: Migrate modules sequentially (Embeddings → Evaluations → RAG → MCP → Chat). Update config mapping and tests per module.
+  - Phase 3: Remove duplicate implementations; keep import shims for one release cycle; announce deprecation in release notes.
+
+  Acceptance Criteria
+
+  - Single, shared CB used by Embeddings, Evaluations, RAG, MCP (and optionally Chat).
+  - All tests pass: python -m pytest -v and coverage unchanged or improved.
+  - Metrics exported under unified names with expected labels; no duplicate metric registration errors.
+  - Config overrides resolve correctly from each category’s existing config files.
+  - No API regressions; same error semantics for open/rejected calls.
+
+  Open Questions
+
+  - Should CB own per-call timeout universally, or leave it to call sites with a helper? (Current plan: optional timeout_seconds in CB wrapper to preserve Evaluations/MCP behavior.)
+  - Do we migrate Chat provider CB now or backlog it?
+  - Do we want per-category defaults in code, or only in config files?
+
+  Timeline
+
+  - Phase 1: 1–2 days (Infra CB, metrics, basic tests, shims).
+  - Phase 2: 2–4 days (module migrations + tests).
+  - Phase 3: 0.5 day (cleanup, docs, deprecations).

   - Owner: Platform / Core
   - Version: 1.0
-  - Status: Proposed
+  - Status: Completed (Stage 7)
+
+  Summary of Outcomes
+
+  - Centralization: 100% of outbound HTTP in app/core and app/services now uses centralized helpers/factories (documented exceptions appear only in documentation examples).
+  - Security: Egress enforced per hop and on proxies (deny-by-default allowlist). Optional TLS minimum version and env-driven leaf-cert pinning supported and tested.
+  - Reliability: Unified retries with decorrelated jitter and Retry-After support; no auto-retry after first body byte for streaming.
+  - Streaming: Standardized SSE helper with deterministic cancellation and final [DONE] ordering; added stress tests for high-chunk scenarios.
+  - Downloads: Atomic rename, checksum and Content-Length validation, resume support; strict Content-Type enabled at call sites where required (audio path enabled).
+  - Observability: Structured outbound logs; metrics exposed (http_client_requests_total, http_client_request_duration_seconds_bucket, http_client_retries_total, http_client_egress_denials_total); optional traceparent injection for OTel.
+  - Monitoring: Grafana dashboard JSON and Prometheus alert rules added (Docs/Monitoring/http_client_grafana_dashboard.json, Docs/Monitoring/http_client_alerts_prometheus.yaml).
+  - Developer experience: Config and .env examples updated (PROXY_ALLOWLIST, TLS flags, HTTP_CERT_PINS); comprehensive MockTransport-based tests for JSON helpers, redirects, proxies, downloads, SSE parsing, TLS, and perf microbenches (PERF=1).
+  - CI enforcement: HTTP usage guard is blocking and passing; prevents direct httpx/requests usage outside approved core files.
+
+  How to Monitor
+
+  - Prometheus metrics endpoints (gated by route toggles):
+      - Prometheus text: GET `/metrics`
+      - JSON metrics: GET `/api/v1/metrics`
+      - Quick checks:
+        - `curl -s http://127.0.0.1:8000/metrics | head`
+        - `curl -s http://127.0.0.1:8000/api/v1/metrics`
+  - OpenTelemetry (optional):
+      - Install exporters (see `tldw_Server_API/app/core/Metrics/README.md`).
+      - Example env:
+        - `OTEL_SERVICE_NAME=tldw_server`
+        - `OTEL_SERVICE_VERSION=1.0.0`
+        - `OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317`
+        - `OTEL_EXPORTER_OTLP_PROTOCOL=grpc`
+        - `OTEL_METRICS_EXPORTER=prometheus,otlp`
+        - `OTEL_TRACES_EXPORTER=otlp`
+      - Server logs indicate OTEL availability on startup.
+  - Dashboards & Alerts:
+      - Grafana: import `Docs/Monitoring/http_client_grafana_dashboard.json`.
+      - Prometheus: load alert rules from `Docs/Monitoring/http_client_alerts_prometheus.yaml`.
+
+  Troubleshooting
+
+  - Egress denials (NetworkError/EgressPolicyError):
+      - Confirm host and scheme are allowed by the server’s egress policy and allowlists.
+      - Redirects are re‑validated per hop; check each `Location` host in the chain.
+      - Proxies are deny‑by‑default; set `PROXY_ALLOWLIST` (hosts or URLs) if a proxy is required.
+      - Metrics: `http_client_egress_denials_total{reason}` increments with the reason label.
+  - Proxy blocked or ignored:
+      - Central client validates proxies against `PROXY_ALLOWLIST`. Dict form (`{"http": "...", "https": "..."}`) is supported.
+      - When `HTTP_TRUST_ENV=false` (default), system proxies are ignored.
+  - Redirect loops or missing Location:
+      - Loops surface as `RetryExhaustedError` or `NetworkError("Invalid/without Location")` depending on hop.
+      - Cap is `HTTP_MAX_REDIRECTS` (default 5). Validate final URL/content‑type matches expectations.
+  - HTTP/2 disabled unexpectedly:
+      - If `h2` is not installed, factories automatically downgrade to HTTP/1.1.
+      - Install `httpx[h2]` to re‑enable HTTP/2; no code change needed.
+  - JSON decode errors:
+      - Helpers validate `Content-Type: application/json`. Pass `require_json_ct=False` (or `accept_mismatch=True` at call sites that permit it) to allow decoding regardless of header.
+      - Large payloads: enforce or raise `HTTP_JSON_MAX_BYTES` at call sites using `max_bytes`.
+  - Streaming stalls/DONE ordering:
+      - SSE helper never retries after first body byte; cancellation propagates via `CancelledError`.
+      - Unified path emits a single final `[DONE]`; for issues check provider adapters and heartbeat intervals.
+  - TLS pinning/min-version failures:
+      - Pinning uses leaf cert SHA‑256 hashes from `HTTP_CERT_PINS` (`host=pinA|pinB,...`).
+      - Enforce min version via `TLS_ENFORCE_MIN_VERSION=true` and `TLS_MIN_VERSION=1.2|1.3`.
+  - Downloads resume anomalies:
+      - If server ignores `Range` and returns 200, downloader overwrites the partial file with full content.
+      - Use `checksum`/`Content-Length` validation and optional `require_content_type` for strictness.

+# Config Normalization PRD (Targeted)
+
+Status: Proposal ready for implementation
+Owner: Core Maintainers
+Target Release: 0.2.x
+
+## 1. Summary
+Normalize configuration across rate limiting, embeddings, and audio quota by introducing one typed settings object per domain. Replace ad‑hoc env/config parsing with a Pydantic Settings façade layered over `tldw_Server_API/app/core/config.py`. Standardize testing via a single `TEST_MODE` switch and unified defaults while retaining backward compatibility for legacy keys.
+
+## 2. Problem Statement
+Multiple modules parse environment variables and `config.txt` independently with custom fallbacks and test overrides, creating drift and brittleness.
+- Duplicated logic exists at:
+  - `tldw_Server_API/app/core/Chat/rate_limiter.py:270`
+  - `tldw_Server_API/app/core/Embeddings/rate_limiter.py:246`
+  - `tldw_Server_API/app/core/Usage/audio_quota.py:281`
+- A central adapter exists (`tldw_Server_API/app/core/config.py:1`) but is not the single source of truth.
+
+Consequences: inconsistent precedence rules, scattered defaults, harder testing, and noisy diffs when adding new options.
+
+## 3. Goals & Success Criteria
+- One typed settings object per domain (RateLimits, Embeddings, AudioQuota, Common).
+- Single precedence order everywhere: environment → config file → hardcoded defaults.
+- Standardize test behavior with `TLDW_TEST_MODE=1` and domain‑specific test defaults.
+- Backward compatibility for existing env names and config keys via aliases.
+- Reduce code duplication and improve readability, validation, and startup diagnostics.
+
+**Success Metrics**
+- Reduced config-related test flakiness and fewer env mutations in tests.
+- Removal of duplicated parsing blocks in the three target modules.
+- Clear startup logs showing effective settings and sources (env/config/default).
+
+## 4. Out of Scope (v1)
+- Global refactor of all configuration domains (LLM providers, RAG, MCP, TTS globals).
+- Changing default values beyond achieving current behavior parity (except test flag normalization).
+- Introducing new external configuration stores or secret managers.
+
+## 5. Personas & Use Cases
+- Developer: Instantiates one settings object per domain; never re‑implements parsing.
+- QA/CI: Sets `TLDW_TEST_MODE=1` and receives stable, test‑friendly defaults.
+- Operator: Configures env or `config.txt` once and observes consistent behavior with clear startup logs.
+
+## 6. Scope
+### In Scope
+- New settings façade package: `tldw_Server_API/app/core/settings/`
+- Integration changes within:
+  - `tldw_Server_API/app/core/Chat/rate_limiter.py`
+  - `tldw_Server_API/app/core/Embeddings/rate_limiter.py`
+  - `tldw_Server_API/app/core/Usage/audio_quota.py`
+- Minimal adapter updates in `tldw_Server_API/app/core/config.py` to support lookups.
+
+### Out of Scope (follow‑ups)
+- LLM provider settings, RAG, MCP, TTS global settings.
+
+## 7. Functional Requirements
+- Common settings
+  - `CommonSettings`: `test_mode` from `TLDW_TEST_MODE`, `environment` from `TLDW_ENV`.
+- Rate limits
+  - `RateLimitSettings`: `chat_rpm`, `chat_tpm`, `chat_burst`, `chat_concurrency`, `enabled`.
+  - Preferred env keys: `TLDW_RATE_CHAT_RPM`, `TLDW_RATE_CHAT_TPM`, `TLDW_RATE_CHAT_BURST`, `TLDW_RATE_CHAT_CONCURRENCY`, `TLDW_RATE_ENABLED`.
+  - Legacy aliases for any existing `TEST_*` and current names used in the code.
+- Embeddings
+  - `EmbeddingSettings`: `provider`, `model`, `rpm`, `max_batch`, `concurrency`, `dims`.
+  - Env keys: `TLDW_EMB_PROVIDER`, `TLDW_EMB_MODEL`, `TLDW_EMB_RPM`, `TLDW_EMB_MAX_BATCH`, `TLDW_EMB_CONCURRENCY`, `TLDW_EMB_DIMS`.
+- Audio quota
+  - `AudioQuotaSettings`: `max_seconds_per_day`, `window_days`, `per_user`, `enabled`.
+  - Env keys: `TLDW_AUDIO_QUOTA_SECONDS_DAILY`, `TLDW_AUDIO_QUOTA_WINDOW_DAYS`, `TLDW_AUDIO_QUOTA_PER_USER`, `TLDW_AUDIO_QUOTA_ENABLED`.
+- Precedence
+  - Environment → `config.py` adapter (reads `config.txt`) → hardcoded defaults.
+- Validation
+  - Reject invalid ranges (negative RPM/TPM, zero window); return clear errors.
+- Test mode
+  - If `test_mode` and a value is unspecified, apply current test‑friendly defaults per domain.
+- Dependency Injection
+  - FastAPI providers: `get_rate_limit_settings()`, `get_embedding_settings()`, `get_audio_quota_settings()`.
+  - Optional constructor injection for unit tests to avoid env mutation.
+- Observability
+  - Log effective settings at startup (redacted secrets), including source markers `[env|config|default]`.
+
+## 8. Non‑Functional Requirements
+- Backwards compatible defaults; no material behavior changes for existing deployments.
+- Minimal overhead; settings load once and are cached for reuse.
+- Consistent error messages and Loguru logging.
+
+## 9. Design Overview
+- Package layout
+  - `tldw_Server_API/app/core/settings/base.py` – shared mixins; source tagging; adapter to `config.py`.
+  - `tldw_Server_API/app/core/settings/common.py` – `CommonSettings`.
+  - `tldw_Server_API/app/core/settings/rate_limits.py` – `RateLimitSettings`.
+  - `tldw_Server_API/app/core/settings/embeddings.py` – `EmbeddingSettings`.
+  - `tldw_Server_API/app/core/settings/audio_quota.py` – `AudioQuotaSettings`.
+- Façade behavior
+  - Pydantic `BaseSettings` classes read env with aliases; fallback to a `config.py` adapter for `[RateLimits]`, `[Embeddings]`, `[Audio-Quota]` sections; otherwise defaults.
+  - Merge logic applies precedence and captures source for logging.
+- Dependency injection
+  - Singleton instances resolved at app startup; overridable in tests via fixtures.
+
+## 10. Data Model
+- In‑memory Pydantic models; no new DB schema.
+- Helper: `ConfigSourceAdapter` for section/key access via `config.py`.
+- Merge function to compute final effective settings per domain with per‑field source metadata.
+
+## 11. APIs & Interfaces
+- FastAPI dependency providers returning domain settings singletons.
+- Optional (debug): authenticated endpoint to inspect effective config: `/api/v1/config/effective` (redacted).
+
+## 12. Implementation Phases
+1. Scaffold settings package and `config.py` adapter; add DI providers. Optional feature flag `TLDW_SETTINGS_V1=1`.
+2. Integrate three target modules to consume settings via DI/constructor args; remove local parsing blocks.
+3. Cleanup: delete dead code and finalize aliases; update docs/examples.
+
+## 13. Migration & Rollout
+- Default to new settings; retain legacy env names via field aliases.
+- During soak, log effective values clearly; if needed, temporarily gate via `TLDW_SETTINGS_V1`.
+- Later minor release removes deprecated env names and parsing remnants.
+
+## 14. Risks & Mitigations
+- Silent behavior drift from defaults → add parity tests; dual logging during rollout.
+- Env name collisions → use `TLDW_*` namespace; keep explicit legacy aliases.
+- Test brittleness from env reliance → prefer injected settings fixtures; minimize env mutation.
+
+## 15. Dependencies & Assumptions
+- Pydantic available in the project environment.
+- `tldw_Server_API/app/core/config.py` remains the adapter for `config.txt`.
+- Existing defaults in the three modules are the source of truth for parity.
+
+## 16. Acceptance Criteria
+- Target modules fetch all configuration via typed settings; no ad‑hoc env parsing remains.
+- `TLDW_TEST_MODE=1` yields consistent test defaults across domains.
+- Precedence (env → config → default) verified by tests.
+- Startup logs show effective settings with sources; sensitive values redacted.
+- Unit and integration tests pass with no behavioral regressions.
+
+## 17. Testing Plan
+- Unit tests (per settings class): precedence resolution, alias handling, validation errors, test‑mode defaults.
+- Integration tests: ensure Chat limiter, Embeddings limiter, and Audio quota behavior is unchanged under representative env/config permutations.
+- Fixtures: `settings_override` to inject domain instances in tests without env pollution.
+- Coverage: include in `python -m pytest --cov=tldw_Server_API --cov-report=term-missing`.
+
+## 18. Timeline (Estimate)
+- Design + scaffolding: 0.5 day
+- Implement settings + adapters: 0.5 day
+- Integrate 3 modules and remove duplication: 0.5–1 day
+- Tests + docs: 0.5–1 day
+- Total: 2–3 days
+
+## 19. Open Questions
+- Enumerate all legacy env keys in use for alias mapping (audit required).
+- Confirm test‑mode default semantics (unlimited vs large but finite rates) with QA.
+- Need per‑provider embeddings rate limits now, or defer?
+- Include an authenticated endpoint to expose effective config, or keep logs only?
+

+
+- Programmatic per-host certificate pinning (leaf certificate SHA-256):
+
+```python
+from tldw_Server_API.app.core.http_client import create_async_client, afetch, RetryPolicy
+
+# Map of host -> set of allowed certificate fingerprints (hex sha256 of DER)
+pins = {

+    resp = await afetch(method="GET", url="https://api.openai.com/v1/models", client=client, retry=RetryPolicy())
+    print(resp.status_code)
+```
+
+Notes
+- Pinning checks the leaf certificate fingerprint (sha256 of the DER cert) before the request proceeds. A mismatch raises an egress/pinning error.
+- Env-driven pinning (built-in parser): set `HTTP_CERT_PINS` to a CSV-style mapping of host to pins
+  - Example: `HTTP_CERT_PINS="api.openai.com=ab12..|cd34..,api.groq.com=ef56.."`
+  - Format: `host=pin1|pin2[,host2=pin3]` where pins are lowercase sha256 hex of the leaf certificate DER.
+  - These pins are attached to clients created by `create_client`/`create_async_client` when `cert_pinning` is not provided.
+
 - Egress & SSRF policy
   - All helpers evaluate the central egress policy (`app/core/Security/egress.py`) before any network I/O and on each redirect hop, and validate proxies.
   - Denies unsupported schemes, disallowed ports, denylisted hosts, and private/reserved IPs by default. See `WORKFLOWS_EGRESS_*` env keys in that module for allow/deny behavior.

+- To preserve provider control lines, set the global env `STREAM_PROVIDER_CONTROL_PASSTHRU=1`
+  or pass `provider_control_passthru=True` to iterators/streams (per-endpoint override).
+- Unknown/dropped control/comment lines are logged at debug level to aid troubleshooting.

 - Export environment variables in your shell or create a temporary `.env` when running targeted suites.

 - Keep heavy toggles disabled by default in CI to control runtime. Enable them locally when validating provider integrations or stress scenarios.

+- Preferred: export a full DSN and all tests will use it:
+  - `export TEST_DATABASE_URL=postgresql://USER:PASS@HOST:PORT/DB`
+  - Example for the default dev container: `postgresql://tldw:tldw@127.0.0.1:5432/tldw_content`

+  1) Container-style `POSTGRES_DB`, `POSTGRES_USER`, `POSTGRES_PASSWORD` (+ `POSTGRES_TEST_HOST`/`POSTGRES_TEST_PORT` if set)
+  2) `TEST_DB_HOST`, `TEST_DB_PORT`, `TEST_DB_NAME`, `TEST_DB_USER`, `TEST_DB_PASSWORD`
+  3) Project defaults (`127.0.0.1:5432`, `tldw_test`, `tldw_user`, `TestPassword123!`)
+- A small helper `tests/helpers/pg_env.py` centralizes this logic. Import `get_pg_env()` or `pg_dsn()` in tests to avoid drift.

 - Public and authenticated sandbox health endpoints.
 - Error semantics: 409 idempotency returns `prior_id`, `key`, `prior_created_at`; 503 `runtime_unavailable` includes the failing `details.runtime`.
 
+Update: Egress Allowlist & DNS Pinning (v0.3)
+- Added helpers to harden allowlist parsing and make DNS pinning explicit:
+  - `expand_allowlist_to_targets(...)` now supports CIDR, IPs, hostnames, wildcard prefixes (`*.example.com`) and suffix tokens (`.example.com`), promoting resolved A records to `/32` CIDRs.
+  - `pin_dns_map(...)` returns `{ host -> [IPs] }` for observability.
+  - `refresh_egress_rules(container_ip, raw_allowlist, label, ...)` revokes labeled rules then reapplies pinned `ACCEPT` targets followed by a `DROP` for the container IP.
+  - Rules are labeled for later cleanup; falls back from `iptables-restore` to iterative `iptables` if needed.
+
 Not yet (planned or in progress)
 - Egress allowlist enforcement and DNS pinning (capability flag present; enforcement WIP).
 - Firecracker runner: real execution parity (scaffold implemented).

+"""Unified Postgres fixtures for tests.
+
+Goals:
+- Single source of truth for resolving Postgres connection settings.
+- Best‑effort reachability check and optional Docker auto‑start for localhost.
+- Function‑scoped temporary database creation and cleanup.
+
+Usage patterns:
+- Request `pg_temp_db` for a per‑test scratch DB. Returns a dict with
+  host/port/user/password/database and a `dsn` field. Skips if Postgres is
+  unreachable and not required.
+- Request `pg_eval_params` for compatibility with existing tests that expect
+  a dict of connection params (host/port/user/password/database).
+- Request `pg_database_config` to get a DatabaseConfig ready for backend
+  creation via DatabaseBackendFactory.
+
+Environment knobs:
+- TEST_DATABASE_URL / DATABASE_URL / POSTGRES_TEST_DSN / POSTGRES_TEST_*
+- TLDW_TEST_POSTGRES_REQUIRED=1 to fail instead of skip when unavailable
+- TLDW_TEST_NO_DOCKER=1 to disable Docker auto‑start
+- TLDW_TEST_PG_IMAGE (default: postgres:18)
+- TLDW_TEST_PG_CONTAINER_NAME (default: tldw_postgres_test)

+### Migrating From Gradio Version (pre-0.1.0)
+- Backup:
+    - `cp -a ./Databases ./Databases.backup`
+- Update configuration:
+    - Copy provider keys to `.env`.
+    - For AuthNZ setup: `cp .env.authnz.template .env && python -m tldw_Server_API.app.core.AuthNZ.initialize`
+- Database migration:
+    - Inspect: `python -m tldw_Server_API.app.core.DB_Management.migrate_db status`
+    - Migrate: `python -m tldw_Server_API.app.core.DB_Management.migrate_db migrate`
+    - Optional: `--db-path /path/to/Media_DB_v2.db` if not using defaults
+    - If migrating content to Postgres later, use the tools under `tldw_Server_API/app/core/DB_Management/` (e.g., migration_tools.py)
+- API changes:
+    - Use FastAPI routes; see http://127.0.0.1:8000/docs. OpenAI-compatible endpoints are available (e.g., `/api/v1/chat/completions`).
+- Frontend:
+    - Legacy: /webui 
+    - Or integrate directly against the API;

+Notes
+- Run compose commands from the repository root. The base compose file at `Dockerfiles/docker-compose.yml` builds with context at the repo root and includes Postgres and Redis services.
+- The legacy WebUI is served at `/webui`; the primary UI is the Next.js client in `tldw-frontend/`.
+- For unified streaming validation in non-prod, prefer the dev overlay above. You can also export `STREAMS_UNIFIED=1` directly in your environment.

 - Backend selection (env):
   - `RG_BACKEND`: `memory` (default) or `redis`
   - `RG_REDIS_FAIL_MODE`: `fail_closed` (default) | `fail_open` | `fallback_memory`
+  - `REDIS_URL`: Redis connection URL (used by RG when backend=redis). If unset, defaults to `redis://127.0.0.1:6379`.
+  - Requests determinism (tests/dev):
+    - `RG_TEST_FORCE_STUB_RATE=1` prefers in‑process sliding‑window rails for requests/tokens when running Redis backend, stabilizing burst vs steady retry‑after behavior in CI.
 - Policy route_map precedence:
   - When `RG_POLICY_STORE=db` is in use, policies (limits) load from the DB store but `route_map` is currently sourced from the YAML file and merged into the snapshot. If both DB and file provide mappings in the future, file route_map takes precedence unless otherwise documented.
   - When `RG_POLICY_STORE=file`, both policies and route_map come from the YAML file at `RG_POLICY_PATH`.
+
+#### DB Policy Store Bootstrap
+- Configure env for DB store (FastAPI reads these on startup):
+  - `RG_POLICY_STORE=db`
+  - `AUTH_MODE=multi_user`
+  - `DATABASE_URL=postgresql://USER:PASSWORD@HOST:5432/DBNAME`
+- Option A — Python bootstrap (no HTTP):
+```
+python - << 'PY'
+import asyncio
+from tldw_Server_API.app.core.Resource_Governance.policy_admin import AuthNZPolicyAdmin
+
+async def main():
+    admin = AuthNZPolicyAdmin()
+    await admin.upsert_policy("chat.default", {"requests": {"rpm": 120, "burst": 2.0}, "tokens": {"per_min": 60000, "burst": 1.5}}, version=1)
+    await admin.upsert_policy("embeddings.default", {"requests": {"rpm": 60, "burst": 1.2}}, version=1)

+    print("Seeded rg_policies (DB store)")
+
+asyncio.run(main())
+PY
+```
+- Option B — Admin API (HTTP):
+  1) Obtain an admin JWT (login as admin in multi-user mode).
+  2) Upsert policies via API:
+```
+curl -X PUT \
+  -H "Authorization: Bearer $ADMIN_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"payload": {"requests": {"rpm": 120, "burst": 2.0}, "tokens": {"per_min": 60000, "burst": 1.5}}, "version": 1}' \

+
+#### Sample Policy YAML (route_map merging)
+- Provide a YAML at `RG_POLICY_PATH` to supply/override `route_map` while using DB-backed policies. Example:
+```
+schema_version: 1
+defaults:
+  fail_mode: fail_closed
+  algorithm:
+    requests: token_bucket
+    tokens: token_bucket
+
+policies:

+    tokens:   { per_min: 60000, burst: 1.5 }
+    scopes: [global, user, conversation]
+  embeddings.default:
+    requests: { rpm: 60, burst: 1.2 }
+    scopes: [user]

 - Test mode precedence:
   - `RG_TEST_BYPASS` overrides Resource Governor behavior when set; otherwise falls back to `TLDW_TEST_MODE`
  - `RG_ENABLE_SIMPLE_MIDDLEWARE`: `true|false` to enable the minimal pre-check middleware for `requests` category using route tags/path mapping.

+  - (Tests) `RG_REAL_REDIS_URL`: optional Redis URL used by RG integration tests; if absent, real-Redis tests are skipped. `REDIS_URL` is also honored.
 
 #### Simple Middleware (opt‑in)
 - Resolution order: path-based mapping (`route_map.by_path`) first, then tag-based mapping (`route_map.by_tag`). Wildcards like `/api/v1/chat/*` match by prefix.

 - Behavior: performs a pre-check/reserve for the `requests` category before calling the endpoint and commits afterwards. On denial, sets `Retry-After` and `X-RateLimit-*` headers. On success, injects accurate `X-RateLimit-*` headers using a governor `peek` when available.
 - Enable by setting `RG_ENABLE_SIMPLE_MIDDLEWARE=true`. It only guards `requests` in this minimal form; streaming/tokens categories require explicit endpoint plumbing for reserve/commit.
 
+- Headers on success/deny:
+  - Deny (429): `Retry-After`, `X-RateLimit-Limit`, `X-RateLimit-Remaining=0`, `X-RateLimit-Reset` (seconds until retry).
+  - Success: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` computed via `peek_with_policy` for precision. When a tokens policy exists and is peek‑able, the middleware also sets `X-RateLimit-Tokens-Remaining` and, if `tokens.per_min` is defined in the active policy, `X-RateLimit-PerMinute-Limit`/`X-RateLimit-PerMinute-Remaining` (best‑effort; exact values depend on the configured backend and policy).
+  - When denial is caused by a category other than `requests` (e.g., `tokens`), the middleware maps `X-RateLimit-*` to that denying category’s effective limit and retry.
+
+#### Diagnostics
+- Capability probe (admin): `GET /api/v1/resource-governor/diag/capabilities`
+  - Returns a small diagnostics object indicating which backend is active and whether Redis Lua paths are available/used, e.g.
+    - `backend`: `memory|redis`
+    - `real_redis`: `true|false` (false when using the in-memory Redis stub)
+    - `tokens_lua_loaded`, `multi_lua_loaded`: booleans for script load state (Redis backend)
+    - `last_used_tokens_lua`, `last_used_multi_lua`: whether those paths were recently exercised
+  - Route is gated by admin auth; in single‑user mode admin is allowed by default.
+  - Requests/acceptance window note: to avoid flakiness near minute boundaries, the Redis backend maintains an acceptance‑window guard for requests and supports `RG_TEST_FORCE_STUB_RATE=1` to prefer local rails during CI.
+
+#### Testing (Real Redis)
+- Optional integration tests validate the multi-key Lua path on a real Redis.
+  - Set one of:
+    - `RG_REAL_REDIS_URL=redis://localhost:6379` (preferred for tests)
+    - or `REDIS_URL=redis://localhost:6379`
+  - Run the gated test:
+    - `pytest -q tldw_Server_API/tests/Resource_Governance/integration/test_redis_real_lua.py`
+  - The `real_redis` fixture verifies connectivity (no in-memory fallback) and skips the test if Redis is unavailable.
+  - Regular RG unit tests use an in-memory Redis stub and do not require a running Redis.
+
+#### Testing (Middleware)
+- Middleware tests run against tiny stub FastAPI apps and don’t require full server startup.
+- Useful env toggles during manual experiments:
+  - `RG_ENABLE_SIMPLE_MIDDLEWARE=1` — enable the minimal pre-check middleware
+  - `RG_MIDDLEWARE_ENFORCE_TOKENS=1` — include `tokens` in middleware reserve/deny
+  - `RG_MIDDLEWARE_ENFORCE_STREAMS=1` — include `streams` in middleware reserve/deny
+- Run the focused tests:
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_simple.py`
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_tokens_headers.py`
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_enforcement_extended.py`
+  - These verify deny/success headers, tokens per-minute headers, and streams Retry-After behavior.
+

 - Users own and control their data; see hardening guide for production
+- Metrics & Grafana
+  - Emitted metrics (core):
+    - `rg_decisions_total{category,scope,backend,result,policy_id}` — allow/deny decisions per category/scope/backend
+    - `rg_denials_total{category,scope,reason,policy_id}` — denial events by reason (e.g., `insufficient_capacity`)
+    - `rg_refunds_total{category,scope,reason,policy_id}` — refund events from commit/refund paths
+    - `rg_concurrency_active{category,scope,policy_id}` — active stream/job leases (gauge)
+  - Cardinality guard:
+    - By default, metrics DO NOT include `entity` labels to avoid high-cardinality pitfalls. If you truly need per-entity sampling, gate it behind `RG_METRICS_ENTITY_LABEL=true` and ensure hashing/masking is applied upstream.
+  - Quick Grafana panel examples:
+    - Allow vs Deny over time (per category):
+      - Query: `sum by (category, result) (rate(rg_decisions_total[5m]))`
+    - Denials by scope (top N):
+      - Query: `topk(5, sum by (scope) (rate(rg_denials_total[5m])))`
+    - Refund activity (tokens):
+      - Query: `sum by (policy_id) (rate(rg_refunds_total{category="tokens"}[5m]))`
+    - Active streams (per scope):
+      - Query: `avg by (scope) (rg_concurrency_active{category="streams"})`

+  - `docker compose -f Dockerfiles/docker-compose.yml -f Dockerfiles/docker-compose.override.yml up -d --build`
+  - Sets production flags, disables API key echo, and tightens defaults.
+
+- Reverse proxy (Caddy): `Dockerfiles/docker-compose.proxy.yml`
+  - `docker compose -f Dockerfiles/docker-compose.yml -f Dockerfiles/docker-compose.proxy.yml up -d --build`
+  - Exposes 80/443 via Caddy; unpublish app port on host.
+
+- Reverse proxy (Nginx): `Dockerfiles/docker-compose.proxy-nginx.yml`
+  - `docker compose -f Dockerfiles/docker-compose.yml -f Dockerfiles/docker-compose.proxy-nginx.yml up -d --build`
+  - Mount `Samples/Nginx/nginx.conf` and your certs.
+
+- Postgres (basic standalone): `Dockerfiles/Dockerfiles/docker-compose.postgres.yml`
+  - Start a standalone Postgres you can point `DATABASE_URL` to.
+  - Example:
+    - `export DATABASE_URL=postgresql://tldw_user:TestPassword123!@localhost:5432/tldw_users`
+    - `docker compose -f Dockerfiles/Dockerfiles/docker-compose.postgres.yml up -d`

+  - `docker compose -f Dockerfiles/docker-compose.yml -f Dockerfiles/Dockerfiles/docker-compose.dev.yml up -d --build`
+  - Sets `STREAMS_UNIFIED=1` (keep off in production until validated).
+
+- Embeddings workers + monitoring: `Dockerfiles/Dockerfiles/docker-compose.embeddings.yml`
+  - Base workers only: `docker compose -f Dockerfiles/Dockerfiles/docker-compose.embeddings.yml up -d`
+  - With monitoring profile (Prometheus + Grafana):
+    - `docker compose -f Dockerfiles/Dockerfiles/docker-compose.embeddings.yml --profile monitoring up -d`

+    - `docker compose -f Dockerfiles/Dockerfiles/docker-compose.embeddings.yml --profile debug up -d`
+  - Scale workers: `docker compose -f Dockerfiles/Dockerfiles/docker-compose.embeddings.yml up -d --scale chunking-workers=3`
+
+## Images
+
+- App image: `Dockerfiles/Dockerfiles/Dockerfile.prod` (built by base compose)
+- Worker image: `Dockerfiles/Dockerfiles/Dockerfile.worker` (used by embeddings compose)
+
+## Notes
+
+- Run compose commands from repo root so relative paths resolve correctly.
+- For production, pair the app with a reverse proxy and set strong secrets in `.env`.
+- GPU for embeddings workers: ensure the host has NVIDIA runtime configured and adjust `CUDA_VISIBLE_DEVICES` as needed in the embeddings compose.
+- To avoid publishing the app port on host when using a proxy overlay, do not also map `8000:8000` in `app`.
+
+## Troubleshooting
+
+- Health checks: `app` responds on `/ready`; `postgres`/`redis` include health checks.
+- If the app fails waiting for DB, verify `DATABASE_URL` and Postgres readiness.
+- Initialize AuthNZ after first boot if running multi-user, or set a strong `SINGLE_USER_API_KEY` for single-user.
+- View full logs: `docker compose ... logs -f`

-## 11. Implementation Plan (Staged)
-
-Stage 1: Abstractions & Baseline (Complete)
-- Goal: Implement `AsyncStream`, `SSEStream`, `WebSocketStream` with base metrics and tests.
-- Success: One Chat SSE path migrated; DONE/error/heartbeat semantics verified with unit tests.
-
-Stage 2: Pass‑through + Timeouts (Complete)
-- Goal: Provider control pass‑through, SSE idle/max enforcement, close‑code guidance.
-- Success: Normalization toggles in place; SSE idle/max tested; metrics labels available.
-
-Stage 3: Pilot Rollout (In Progress)
-- Goal: Adopt under `STREAMS_UNIFIED` for key endpoints; validate with WebUI and two providers.
-- Current pilots:
-  - Chat SSE: Character chat, main chat completions, document‑generation.
-  - Embeddings SSE orchestrator.
-  - Evaluations SSE (A/B tests and batch emitters).
-  - Jobs Admin SSE (events outbox, retains `id:` pass‑through).
-  - Prompt Studio SSE fallback (when flag enabled).
-  - Audio WS and MCP WS using `WebSocketStream` (JSON‑RPC preserved for MCP; compat `error_type` shims).
-- Remaining work for Stage 3:
-  - Non‑prod validation with WebUI across two providers; ensure no duplicate `[DONE]` and heartbeats visible.
-  - Expand unit/integration tests for backpressure and long‑running sessions (SSE heartbeats not starved; WS idle close behavior).
-  - Add/verify provider control pass‑through at call sites that depend on `event:`/`id:`.
-
-Stage 4: Broader Adoption (Planned)
-- Goal: Migrate any remaining bespoke streaming code paths, preserve domain payloads, and standardize lifecycle.
-- Targets to confirm/migrate:
-  - Any residual Chat/Character local SSE helpers (delete after flip).
-  - Embeddings orchestrator legacy code path (remove once default flips).
-  - Jobs PG outbox test hardening and re‑enablement.
-
-Stage 5: Cleanup & Default Flip (Planned)
-- Goal: Remove legacy helpers, flip `STREAMS_UNIFIED` default on in non‑prod → prod.
-- Rollback: Toggle `STREAMS_UNIFIED=0` to revert to legacy per‑endpoint implementations.
-
-Test Matrix (High‑level)
-- SSE
-  - Chat (character, completions, doc‑gen): DONE dedup, errors, heartbeats, backpressure.
-  - Embeddings orchestrator: `event: summary`, heartbeats, idle/max.
-  - Evaluations: event cadence, DONE.
-  - Jobs Admin: `id:` pass‑through, paging, SSE stream.
-  - Prompt Studio fallback: DONE and heartbeat parity.
-- WebSocket
-  - Audio: ping, compat `error_type`, quota → 1008, internal → 1011.
-  - MCP: ping/idle close, JSON‑RPC parse errors, no event‑frame wrapping.
-- Flags
-  - `STREAMS_UNIFIED` on/off parity; `STREAM_PROVIDER_CONTROL_PASSTHRU` per‑endpoint overrides.
-
-Rollback Notes
-- Primary rollback is configuration only: set `STREAMS_UNIFIED=0` to restore legacy paths.
-- Keep compat shims (`error_type`) until all clients migrate to `code`+`message`.
-- If SSE buffering observed under proxies, prefer `heartbeat_mode=data` and verify `X‑Accel‑Buffering: no` in ingress.

 Audio WS legacy quota close code
 - Current behavior: For client compatibility, the Audio WS handler emits an `error` frame with `error_type: "quota_exceeded"` and closes with code `4003` when quotas are exceeded.
 - Target behavior: Migrate to standardized close code `1008` (Policy Violation) with structured `{type: "error", code: "quota_exceeded", message, data?}` and without the legacy `error_type` field once downstream clients have updated.
 - Migration plan:
   - Phase 1 (current): Keep `4003` and include `error_type` alias (compat_error_type=True) in `WebSocketStream` for Audio. Documented in API/SDK release notes.
-  - Phase 2 (flagged pilot): Expose an opt‑in environment toggle (ops only) to switch close code to `1008` while still including `error_type` for a release.
-  - Phase 3 (default switch): Change default to `1008` and keep `error_type` for one additional release.
-  - Phase 4 (cleanup): Remove `error_type` alias for Audio WS and rely solely on `code` + `message`.
+  - Phase 2 (flagged pilot): Expose an opt‑in environment toggle (ops only) to switch close code to `1008` while still including `error_type` for a release. Target: next minor release (v0.1.1).

+  - Phase 4 (cleanup): Remove `error_type` alias for Audio WS and rely solely on `code` + `message`. Target: subsequent minor (v0.1.3).
   - Acceptance: No client breakages reported in non‑prod → prod flips; tests updated to assert `1008`.

+- Prefer structured sends using `SSEStream.send_json` / `SSEStream.send_event` and `WebSocketStream.send_json`.
+- Raw SSE lines via `SSEStream.send_raw_sse_line` are allowed only for legacy provider pass-through during migration; add a brief code comment (e.g., "legacy pass-through; to be removed after rollout").
+- Do not wrap domain WS payloads in event frames for MCP/Audio — keep JSON‑RPC (MCP) and audio partials as-is. Use standardized lifecycle only: `ping`, `error`, `done`.
+- Labels must be low-cardinality (e.g., `component`, `endpoint`) — never user/session IDs.
+- Close codes: map errors per PRD (e.g., `quota_exceeded` → frame + close `1008`; idle timeout → `1001`).

-## HTTP Client & Egress
-
-- All outbound HTTP calls are being consolidated on a unified `http_client` layer with security, retries, and observability baked in.
-- Egress policy is enforced before I/O, on each redirect hop, and for proxies. Private/reserved IPs are blocked by default.
-
-Key configuration (env)
-- Timeouts: `HTTP_CONNECT_TIMEOUT`, `HTTP_READ_TIMEOUT`, `HTTP_WRITE_TIMEOUT`, `HTTP_POOL_TIMEOUT`
-- Limits: `HTTP_MAX_CONNECTIONS`, `HTTP_MAX_KEEPALIVE_CONNECTIONS`
-- Retries: `HTTP_RETRY_ATTEMPTS`, `HTTP_BACKOFF_BASE_MS`, `HTTP_BACKOFF_CAP_S`
-- Redirects/Proxies: `HTTP_MAX_REDIRECTS`, `HTTP_TRUST_ENV`, `PROXY_ALLOWLIST`
-- JSON & Headers: `HTTP_JSON_MAX_BYTES`, `HTTP_DEFAULT_USER_AGENT`
-- Transport/TLS: `HTTP3_ENABLED`, `TLS_ENFORCE_MIN_VERSION`, `TLS_MIN_VERSION`, `TLS_CERT_PINS_SPKI_SHA256`
-- Egress policy: see `tldw_Server_API/app/core/Security/egress.py` (allow/deny/private IP envs)

-- HTTP/2 is preferred, with automatic downgrade when `h2` is not installed. HTTP/3 is available behind a flag when supported.
-- Structured logs redact sensitive headers; metrics are exported when telemetry is configured.

 - Design notes (WIP features): `Docs/Design/` - e.g., `Docs/Design/Custom_Scrapers_Router.md`
 
 ### Resource Governor Config
-- Overview & PRD: `Docs/Design/Resource_Governor_PRD.md`
-- Policy store selection (env):
-  - `RG_POLICY_STORE`: `file` (default) or `db`
-  - `RG_POLICY_PATH`: path to YAML when using `file` store (defaults to `tldw_Server_API/Config_Files/resource_governor_policies.yaml`)
-  - `RG_POLICY_RELOAD_ENABLED`: `true|false` (default `true`)
-  - `RG_POLICY_RELOAD_INTERVAL_SEC`: reload interval seconds (default `10`)
-- Backend selection (env):
-  - `RG_BACKEND`: `memory` (default) or `redis`
-  - `RG_REDIS_FAIL_MODE`: `fail_closed` (default) | `fail_open` | `fallback_memory`
-  - `REDIS_URL`: Redis connection URL (used by RG when backend=redis). If unset, defaults to `redis://127.0.0.1:6379`.
-  - Requests determinism (tests/dev):
-    - `RG_TEST_FORCE_STUB_RATE=1` prefers in‑process sliding‑window rails for requests/tokens when running Redis backend, stabilizing burst vs steady retry‑after behavior in CI.
-- Policy route_map precedence:
-  - When `RG_POLICY_STORE=db` is in use, policies (limits) load from the DB store but `route_map` is currently sourced from the YAML file and merged into the snapshot. If both DB and file provide mappings in the future, file route_map takes precedence unless otherwise documented.
-  - When `RG_POLICY_STORE=file`, both policies and route_map come from the YAML file at `RG_POLICY_PATH`.
-
-#### DB Policy Store Bootstrap
-- Configure env for DB store (FastAPI reads these on startup):
-  - `RG_POLICY_STORE=db`
-  - `AUTH_MODE=multi_user`
-  - `DATABASE_URL=postgresql://USER:PASSWORD@HOST:5432/DBNAME`
-- Option A — Python bootstrap (no HTTP):
-```

-async def main():

-
-#### Sample Policy YAML (route_map merging)
-- Provide a YAML at `RG_POLICY_PATH` to supply/override `route_map` while using DB-backed policies. Example:
-```
-schema_version: 1
-defaults:
-  fail_mode: fail_closed
-  algorithm:
-    requests: token_bucket
-    tokens: token_bucket
-
-policies:
-  chat.default:
-    requests: { rpm: 120, burst: 2.0 }
-    tokens:   { per_min: 60000, burst: 1.5 }
-    scopes: [global, user, conversation]
-  embeddings.default:
-    requests: { rpm: 60, burst: 1.2 }
-    scopes: [user]
-
-route_map:
-  by_tag:
-    chat: chat.default
-    embeddings: embeddings.default
-  by_path:
-    "/api/v1/chat/*": chat.default
-    "/api/v1/embeddings*": embeddings.default
-```
-- When `RG_POLICY_STORE=db` is active, the loader merges the file’s `route_map` into the snapshot containing DB policies. File `route_map` takes precedence on conflicts.
-- Proxy/IP scoping (env):
-  - `RG_TRUSTED_PROXIES`: comma-separated CIDRs of reverse proxies
-  - `RG_CLIENT_IP_HEADER`: trusted header name (e.g., `X-Forwarded-For` or `CF-Connecting-IP`)
-- Metrics cardinality (env):
- - `RG_METRICS_ENTITY_LABEL`: `true|false` (default `false`); when true, metrics may include a hashed entity label
-- Test mode precedence:
-  - `RG_TEST_BYPASS` overrides Resource Governor behavior when set; otherwise falls back to `TLDW_TEST_MODE`
- - `RG_ENABLE_SIMPLE_MIDDLEWARE`: `true|false` to enable the minimal pre-check middleware for `requests` category using route tags/path mapping.
-  - `RG_MIDDLEWARE_ENFORCE_TOKENS`: `true|false` to include `tokens` in middleware enforcement (adds precise tokens headers on success; per-minute headers on deny when policy defines `tokens.per_min`).
-  - `RG_MIDDLEWARE_ENFORCE_STREAMS`: `true|false` to include `streams` in middleware enforcement (sets `Retry-After` on deny).
-  - (Tests) `RG_REAL_REDIS_URL`: optional Redis URL used by RG integration tests; if absent, real-Redis tests are skipped. `REDIS_URL` is also honored.
-
-#### Simple Middleware (opt‑in)
-- Resolution order: path-based mapping (`route_map.by_path`) first, then tag-based mapping (`route_map.by_tag`). Wildcards like `/api/v1/chat/*` match by prefix.
-- Entity derivation: prefers authenticated user (`user:{id}`), then API key id/hash (`api_key:{id|hash}`), then trusted proxy IP header via `RG_CLIENT_IP_HEADER` when `RG_TRUSTED_PROXIES` contains the peer; otherwise falls back to `request.client.host`.
-- Behavior: performs a pre-check/reserve for the `requests` category before calling the endpoint and commits afterwards. On denial, sets `Retry-After` and `X-RateLimit-*` headers. On success, injects accurate `X-RateLimit-*` headers using a governor `peek` when available.
-- Enable by setting `RG_ENABLE_SIMPLE_MIDDLEWARE=true`. It only guards `requests` in this minimal form; streaming/tokens categories require explicit endpoint plumbing for reserve/commit.
-
-- Headers on success/deny:
-  - Deny (429): `Retry-After`, `X-RateLimit-Limit`, `X-RateLimit-Remaining=0`, `X-RateLimit-Reset` (seconds until retry).
-  - Success: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` computed via `peek_with_policy` for precision. When a tokens policy exists and is peek‑able, the middleware also sets `X-RateLimit-Tokens-Remaining` and, if `tokens.per_min` is defined in the active policy, `X-RateLimit-PerMinute-Limit`/`X-RateLimit-PerMinute-Remaining` (best‑effort; exact values depend on the configured backend and policy).
-  - When denial is caused by a category other than `requests` (e.g., `tokens`), the middleware maps `X-RateLimit-*` to that denying category’s effective limit and retry.
-
-#### Diagnostics
-- Capability probe (admin): `GET /api/v1/resource-governor/diag/capabilities`
-  - Returns a small diagnostics object indicating which backend is active and whether Redis Lua paths are available/used, e.g.
-    - `backend`: `memory|redis`
-    - `real_redis`: `true|false` (false when using the in-memory Redis stub)
-    - `tokens_lua_loaded`, `multi_lua_loaded`: booleans for script load state (Redis backend)
-    - `last_used_tokens_lua`, `last_used_multi_lua`: whether those paths were recently exercised
-  - Route is gated by admin auth; in single‑user mode admin is allowed by default.
-  - Requests/acceptance window note: to avoid flakiness near minute boundaries, the Redis backend maintains an acceptance‑window guard for requests and supports `RG_TEST_FORCE_STUB_RATE=1` to prefer local rails during CI.
-
-#### Testing (Real Redis)
-- Optional integration tests validate the multi-key Lua path on a real Redis.
-  - Set one of:
-    - `RG_REAL_REDIS_URL=redis://localhost:6379` (preferred for tests)
-    - or `REDIS_URL=redis://localhost:6379`
-  - Run the gated test:
-    - `pytest -q tldw_Server_API/tests/Resource_Governance/integration/test_redis_real_lua.py`
-  - The `real_redis` fixture verifies connectivity (no in-memory fallback) and skips the test if Redis is unavailable.
-  - Regular RG unit tests use an in-memory Redis stub and do not require a running Redis.
-
-#### Testing (Middleware)
-- Middleware tests run against tiny stub FastAPI apps and don’t require full server startup.
-- Useful env toggles during manual experiments:
-  - `RG_ENABLE_SIMPLE_MIDDLEWARE=1` — enable the minimal pre-check middleware
-  - `RG_MIDDLEWARE_ENFORCE_TOKENS=1` — include `tokens` in middleware reserve/deny
-  - `RG_MIDDLEWARE_ENFORCE_STREAMS=1` — include `streams` in middleware reserve/deny
-- Run the focused tests:
-  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_simple.py`
-  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_tokens_headers.py`
-  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_enforcement_extended.py`
-  - These verify deny/success headers, tokens per-minute headers, and streams Retry-After behavior.

-
-### What is this Project?
-- **What it is now:**
-  - A tool that can ingest: audio, videos, articles, free form text, documents, and books as text into a personal, database, so that you can then search and chat with it at any time.
-    - (+ act as a nice way of creating your personal 'media' database, a personal digital library with search!)
-  - And of course, this is all open-source/free, with the idea being that this can massively help people in their efforts of research and learning.
-    - I don't plan to pivot and turn this into a commercial project. I do plan to make a server version of it, with the potential for offering a hosted version of it, and am in the process of doing so. The hosted version will be 95% the same, missing billing and similar from the open source branch.
-    - I'd like to see this project be used in schools, universities, and research institutions, or anyone who wants to keep a record of what they've consumed and be able to search and ask questions about it.
-    - I believe that this project can be a great tool for learning and research, and I'd like to see it develop to a point where it could be reasonably used as such.
-    - In the meantime, if you don't care about data ownership or privacy, https://notebooklm.google/ is a good alternative that works and is free.
-- **Where its headed:**
-  - Act as a Multi-Purpose Research tool. The idea being that there is so much data one comes across, and we can store it all as text. (with tagging!)
-  - Imagine, if you were able to keep a copy of every talk, research paper or article you've ever read, and have it at your fingertips at a moments notice.
-  - Now, imagine if you could ask questions about that data/information(LLM), and be able to string it together with other pieces of data, to try and create sense of it all (RAG)
-  - Basically a [cheap foreign knockoff](https://tvtropes.org/pmwiki/pmwiki.php/Main/ShoddyKnockoffProduct) [`Young Lady's Illustrated Primer`](https://en.wikipedia.org/wiki/The_Diamond_Age) that you'd buy from some [shady dude in a van at a swap meet](https://tvtropes.org/pmwiki/pmwiki.php/Main/TheLittleShopThatWasntThereYesterday).
-    * Some food for thought: https://notes.andymatuschak.org/z9R3ho4NmDFScAohj3J8J3Y
-    * I say this recognizing the inherent difficulties in replicating such a device and acknowledging the current limitations of technology.
-  - This is a free-time project, so I'm not going to be able to work on it all the time, but I do have some ideas for where I'd like to take it.
-    - I view this as a personal tool I'll ideally continue to use for some time until something better/more suited to my needs comes along.
-    - Until then, I plan to continue working on this project and improving as much as possible.
-    - If I can't get a "Young Lady's Illustrated Primer" in the immediate, I'll just have to hack together some poor imitation of one....

-### Local Models I recommend
-- These are just the 'standard smaller' models I recommend, there are many more out there, and you can use any of them with this project.
-  - One should also be aware that people create 'fine-tunes' and 'merges' of existing models, to create new models that are more suited to their needs.
-  - This can result in models that may be better at some tasks but worse at others, so it's important to test and see what works best for you.

-
-For commercial API usage for use with this project: Latest Anthropic/ChatGPT/Gemini Models.
-Flipside I would say none, honestly. The (largest players) will gaslight you and charge you money for it. Fun.
-That being said they obviously can provide help/be useful(helped me make this app), but it's important to remember that they're not your friend, and they're not there to help you. They are there to make money not off you, but off large institutions and your data.
-You are just a stepping stone to their goals.
-
-From @nrose 05/08/2024 on Threads:
-```
-No, it’s a design. First they train it, then they optimize it. Optimize it for what- better answers?
-  No. For efficiency.
-Per watt. Because they need all the compute they can get to train the next model.So it’s a sawtooth.
-The model declines over time, then the optimization makes it somewhat better, then in a sort of
-  reverse asymptote, they dedicate all their “good compute” to the next bigger model.Which they then
-  trim down over time, so they can train the next big model… etc etc.
-None of these companies exist to provide AI services in 2024. They’re only doing it to finance the
- things they want to build in 2025 and 2026 and so on, and the goal is to obsolete computing in general
-  and become a hidden monopoly like the oil and electric companies.
-2024 service quality is not a metric they want to optimize, they’re forced to, only to maintain some
-  directional income
-```
-
-As an update to this, looking back a year, it still stands true, and I would only change that you're less likely to insult the model at this point. (As long as you're not using sonnet...)

+# Resource Governor
+
+Centralized rate limiting and concurrency control with policy-based configuration, DB/file-backed stores, and optional Redis backend. This module enforces request, token, and stream limits across endpoints and integrates with FastAPI via helpers and optional middleware.
+
+## Overview & PRD
+- Design PRD: `Docs/Design/Resource_Governor_PRD.md`
+- Example policies YAML: `tldw_Server_API/Config_Files/resource_governor_policies.yaml`
+
+## Policy Store Selection (env)
+- `RG_POLICY_STORE`: `file` (default) or `db`
+- `RG_POLICY_PATH`: path to YAML when using `file` store (defaults to `tldw_Server_API/Config_Files/resource_governor_policies.yaml`)
+- `RG_POLICY_RELOAD_ENABLED`: `true|false` (default `true`)
+- `RG_POLICY_RELOAD_INTERVAL_SEC`: reload interval in seconds (default `10`)
+
+## Backend Selection (env)
+- `RG_BACKEND`: `memory` (default) or `redis`
+- `RG_REDIS_FAIL_MODE`: `fail_closed` (default) | `fail_open` | `fallback_memory`
+- `REDIS_URL`: Redis connection URL (used when backend=redis). If unset, defaults to `redis://127.0.0.1:6379`.
+- Determinism (tests/dev): `RG_TEST_FORCE_STUB_RATE=1` prefers in‑process rails for requests/tokens when running Redis backend, stabilizing burst vs steady retry‑after behavior in CI.
+
+## DB Policy Store Bootstrap
+
+Configure env for DB store and AuthNZ:
+- `RG_POLICY_STORE=db`
+- `AUTH_MODE=multi_user`
+- `DATABASE_URL=postgresql://USER:PASSWORD@HOST:5432/DBNAME`
+
+Option A — Python bootstrap (no HTTP):
+```
+python - << 'PY'
+import asyncio
+from tldw_Server_API.app.core.Resource_Governance.policy_admin import AuthNZPolicyAdmin
+
+async def main():
+    admin = AuthNZPolicyAdmin()
+    await admin.upsert_policy("chat.default", {"requests": {"rpm": 120, "burst": 2.0}, "tokens": {"per_min": 60000, "burst": 1.5}}, version=1)
+    await admin.upsert_policy("embeddings.default", {"requests": {"rpm": 60, "burst": 1.2}}, version=1)
+    await admin.upsert_policy("audio.default", {"streams": {"max_concurrent": 2, "ttl_sec": 90}}, version=1)
+    print("Seeded rg_policies (DB store)")
+
+asyncio.run(main())
+PY
+```
+
+Option B — Admin API (HTTP):
+1) Obtain an admin JWT (login as admin in multi-user mode).
+2) Upsert policies via API:
+```

+    requests: token_bucket
+    tokens: token_bucket
+
+policies:
+  chat.default:
+    requests: { rpm: 120, burst: 2.0 }
+    tokens:   { per_min: 60000, burst: 1.5 }
+    scopes: [global, user, conversation]
+  embeddings.default:
+    requests: { rpm: 60, burst: 1.2 }
+    scopes: [user]
+
+route_map:
+  by_tag:
+    chat: chat.default
+    embeddings: embeddings.default
+  by_path:
+    "/api/v1/chat/*": chat.default
+    "/api/v1/embeddings*": embeddings.default
+```
+
+Notes
+- When `RG_POLICY_STORE=db` is active, the loader merges the file’s `route_map` into the snapshot containing DB policies. File `route_map` takes precedence on conflicts.
+- Proxy/IP scoping (env):
+  - `RG_TRUSTED_PROXIES`: comma-separated CIDRs of reverse proxies
+  - `RG_CLIENT_IP_HEADER`: trusted header name (e.g., `X-Forwarded-For` or `CF-Connecting-IP`)
+- Metrics cardinality (env): `RG_METRICS_ENTITY_LABEL`: `true|false` (default `false`)
+- Test mode precedence: `RG_TEST_BYPASS` overrides Resource Governor behavior when set; otherwise falls back to `TLDW_TEST_MODE`
+
+## Simple Middleware (opt‑in)
+
+- Resolution order: path-based mapping (`route_map.by_path`) first, then tag-based mapping (`route_map.by_tag`). Wildcards like `/api/v1/chat/*` match by prefix.
+- Entity derivation: prefers authenticated user (`user:{id}`), then API key id/hash (`api_key:{id|hash}`), then trusted proxy IP header via `RG_CLIENT_IP_HEADER` when `RG_TRUSTED_PROXIES` contains the peer; otherwise falls back to `request.client.host`.
+- Behavior: performs a pre-check/reserve for the `requests` category before calling the endpoint and commits afterwards. On denial, sets `Retry-After` and `X-RateLimit-*` headers. On success, injects accurate `X-RateLimit-*` headers using a governor `peek` when available.
+- Enable: set `RG_ENABLE_SIMPLE_MIDDLEWARE=true`. It only guards `requests` in this minimal form; streaming/tokens categories require explicit endpoint reserve/commit plumbing.
+
+Headers on success/deny:
+- Deny (429): `Retry-After`, `X-RateLimit-Limit`, `X-RateLimit-Remaining=0`, `X-RateLimit-Reset` (seconds until retry).
+- Success: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` computed via peek. When a tokens policy exists and is peek‑able, the middleware also sets `X-RateLimit-Tokens-Remaining` and, if `tokens.per_min` is defined, `X-RateLimit-PerMinute-Limit`/`X-RateLimit-PerMinute-Remaining`.
+- When denial is caused by a category other than `requests` (e.g., `tokens`), the middleware maps `X-RateLimit-*` to that denying category’s effective limit and retry.
+
+## Diagnostics
+
+- Capability probe (admin): `GET /api/v1/resource-governor/diag/capabilities`
+  - Returns: `backend`, `real_redis`, `tokens_lua_loaded`, `multi_lua_loaded`, `last_used_tokens_lua`, `last_used_multi_lua`.
+  - Route is gated by admin auth; in single‑user mode admin is allowed by default.
+  - To avoid minute-boundary flakiness, Redis backend maintains an acceptance‑window guard for requests; `RG_TEST_FORCE_STUB_RATE=1` prefers local rails during CI.
+
+## Testing
+
+### Real Redis (optional)
+- Optional integration tests validate the multi-key Lua path on a real Redis.
+  - Set one of: `RG_REAL_REDIS_URL=redis://localhost:6379` (preferred) or `REDIS_URL=redis://localhost:6379`
+  - Run: `pytest -q tldw_Server_API/tests/Resource_Governance/integration/test_redis_real_lua.py`
+  - The `real_redis` fixture verifies connectivity (no in-memory fallback) and skips if Redis unavailable.
+
+### Middleware
+- Middleware tests run against tiny stub FastAPI apps and don’t require full server startup.
+- Useful env toggles during manual experiments:
+  - `RG_ENABLE_SIMPLE_MIDDLEWARE=1`
+  - `RG_MIDDLEWARE_ENFORCE_TOKENS=1`
+  - `RG_MIDDLEWARE_ENFORCE_STREAMS=1`
+- Tests:
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_simple.py`
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_tokens_headers.py`
+  - `pytest -q tldw_Server_API/tests/Resource_Governance/test_middleware_enforcement_extended.py`

+
+## Unified Postgres Fixtures (Auto-Provisioning)
+
+The suite provides unified Postgres fixtures under `tests/_plugins/postgres.py`:
+
+- `pg_server` (session): resolves connection parameters via `tests/helpers/pg_env.py` and ensures reachability. If the target is localhost and not reachable, it will attempt to auto-start a Docker Postgres (`postgres:18`).
+- `pg_temp_db` (function): creates a fresh temporary database for each test via CREATE DATABASE and drops it at teardown. Returns a dict with `host`, `port`, `user`, `password`, `database`, `dsn`.
+- `pg_eval_params` and `pg_database_config`: convenience wrappers used by various tests.
+
+Automatic Docker fallback
+- If the resolved host is local and either:
+  - no Postgres is listening on the target port, or
+  - CREATE DATABASE fails due to insufficient privileges on an existing server,
+  the fixture will attempt to start a local Docker container with the resolved `user/password` and retry. If the primary port is busy but privileges are wrong, the fixture falls back to an alternate port (default `5434`).
+
+Environment toggles
+- `POSTGRES_TEST_DSN` / `JOBS_DB_URL` / `TEST_DATABASE_URL` / `DATABASE_URL`: explicit DSNs (highest precedence for different suites).
+- Container-style parts: `POSTGRES_TEST_HOST`, `POSTGRES_TEST_PORT`, `POSTGRES_TEST_USER`, `POSTGRES_TEST_PASSWORD`, `POSTGRES_TEST_DB`.
+- `TLDW_TEST_NO_DOCKER=1`: disable auto-start; tests will skip (or fail if required) when Postgres is unavailable.
+- `TLDW_TEST_PG_IMAGE` (default `postgres:18`), `TLDW_TEST_PG_CONTAINER_NAME` (default `tldw_postgres_test`): control the auto-started container.
+- `TLDW_TEST_PG_ALT_PORT` (default `5434`): alternate port used when an existing local Postgres is reachable but lacks privileges.
+- `TLDW_TEST_PG_DEBUG=1`: verbose diagnostics from the fixture (resolved DSN, connect errors, fallback attempts).
+- `TLDW_TEST_POSTGRES_REQUIRED=1`: fail instead of skip when Postgres cannot be provisioned.
+
+Minimal commands
+- Install drivers: `pip install -e .[db_postgres]`
+- Let the fixtures provision Postgres automatically: `pytest -q -k "postgres" -rs`
+- Show provisioning details: `TLDW_TEST_PG_DEBUG=1 pytest -q -k "postgres" -rs -s`
+
+Jobs suite notes
+- Jobs tests are gated off by default. Enable them with `RUN_JOBS=1`.
+- Jobs PG tests use `jobs_pg_dsn` (which internally allocates a per-test DB via the unified fixtures). Example:
+  - `RUN_JOBS=1 pytest -q tldw_Server_API/tests/Jobs -k "postgres and ttl" -rs`

 - The repository ships a `docker-compose.yml` with a `postgres` service. To run Jobs on Postgres when using Compose:
   - Set the DSN using the `postgres` service hostname inside the Compose network:
-    - `export JOBS_DB_URL=postgresql://tldw_user:ChangeMeStrong123!@postgres:5432/tldw_users`
+    - `export JOBS_DB_URL=postgresql://tldw_user:TestPassword123!@postgres:5432/tldw_users`
   - Start services:
     - `docker compose up --build`
   - From your host, you can also connect via the published port:
-    - `export JOBS_DB_URL=postgresql://tldw_user:ChangeMeStrong123!@localhost:5432/tldw_users`
+    - `export JOBS_DB_URL=postgresql://tldw_user:TestPassword123!@localhost:5432/tldw_users`
   - The Jobs manager will auto-provision the schema on first use.
 
 ### Running Postgres Jobs tests
 
 - Ensure a Postgres instance is available (e.g., via Compose above) and set one of:
-  - `export JOBS_DB_URL=postgresql://tldw_user:ChangeMeStrong123!@localhost:5432/tldw_users`
+  - `export JOBS_DB_URL=postgresql://tldw_user:TestPassword123!@localhost:5432/tldw_users`
   - or `export POSTGRES_TEST_DSN=postgresql://...`
 - Run only PG-marked Jobs tests:
   - `python -m pytest -m "pg_jobs" -v tldw_Server_API/tests/Jobs`

+### Session Encryption Key
+
+- Purpose: Encrypts session tokens at rest using Fernet.
+- Configure explicitly with `SESSION_ENCRYPTION_KEY` (urlsafe base64, 32-byte key when decoded). If not set, a key is persisted to disk.
+- Persistence locations (searched in order):
+  - Default: `PROJECT_ROOT/Config_Files/session_encryption.key` (tests set `core_settings["PROJECT_ROOT"]`).
+  - Fallback/alternate: `tldw_Server_API/Config_Files/session_encryption.key`.
+- Force API path storage: set `SESSION_KEY_STORAGE=api` to persist and prefer `tldw_Server_API/Config_Files/session_encryption.key`.
+  - On startup, if a valid key exists at project root and the API path is missing/invalid, the manager migrates the key to the API path (0600 perms) and logs a notice.
+- Security: file must be a regular file, owned by the current user, and is written with `0600` permissions; symlinks and invalid contents are rejected.
 - Concurrency & Performance:
   - Async DB paths for asyncpg/aiosqlite; Redis-backed counters when available.
   - Token/JTI blacklist checks cached; rate limits use token buckets with burst support.

-
-## Design Decisions
-
-### 1. Single-User Optimization
-
-**Decision**: Optimize for single-user TUI rather than multi-user web service.
-
-**Implementation**:
-- Persistent database connections (no pooling)
-- Simplified threading model (max 4 workers)
-- Local file-based ChromaDB
-- In-memory LRU caching
-- No user authentication/isolation
-
-**Rationale**: Reduces complexity and improves performance for the target use case.
-
-### 2. Modular Architecture
-
-**Decision**: Split functionality into focused modules following Single Responsibility Principle.
-
-**Modules**:
-- `config.py`: All configuration logic
-- `retrieval.py`: Document retrieval strategies
-- `processing.py`: Ranking and deduplication
-- `generation.py`: LLM interaction
-- `app.py`: Orchestration only
-
-**Benefits**:
-- Easier testing and maintenance
-- Clear dependencies
-- Parallel development possible
-
-### 3. Strategy Pattern
-
-**Decision**: Use strategy pattern for extensibility.
-
-**Implementation**:
-```python
-class RetrieverStrategy(ABC):
-    @abstractmethod
-    async def retrieve(...) -> SearchResult
-
-class ProcessingStrategy(ABC):
-    @abstractmethod
-    def process(...) -> RAGContext
-
-class GenerationStrategy(ABC):
-    @abstractmethod
-    async def generate(...) -> str
-```
-
-**Benefits**:
-- Easy to add new data sources
-- Swappable algorithms
-- Clean interfaces
-
-### 4. Async-First Design
-
-**Decision**: Use async/await throughout for better TUI responsiveness.
-
-**Implementation**:
-- All I/O operations are async
-- Concurrent retrieval from multiple sources
-- Streaming support for progressive updates
-
-**Benefits**:
-- Non-blocking UI
-- Better resource utilization
-- Natural fit for TUI event loop
-
-### 5. Hybrid Search
-
-**Decision**: Combine keyword (FTS5) and vector search.
-
-**Implementation**:
-```python
-class HybridRetriever:
-    def __init__(self, keyword_retriever, vector_retriever, alpha=0.5):
-        # alpha controls the balance (0=keyword only, 1=vector only)
-```
-
-**Benefits**:
-- Better search quality
-- Handles both exact matches and semantic similarity
-- User-configurable balance
-
-### 6. Configuration System
-
-**Decision**: Integrate with existing TOML configuration.
-
-**Implementation**:
-- Structured configuration classes with validation
-- Environment variable overrides
-- Hot-reloading capability
-
-**Example**:
-```toml
-[rag]
-batch_size = 32
-
-[rag.retriever]
-hybrid_alpha = 0.7
-
-[rag.cache]
-enable_cache = true
-```
-
-### 7. Caching Strategy
-
-**Decision**: Multi-level caching with different TTLs.
-
-**Implementation**:
-- LRU cache for search results
-- Persistent cache for embeddings
-- Configurable TTLs per cache type
-
-**Benefits**:
-- Faster repeated queries
-- Reduced LLM calls
-- Efficient memory usage
-
-### 8. Error Handling
-
-**Decision**: Specific exception types with graceful degradation.
-
-**Implementation**:
-```python
-class RAGError(Exception): pass
-class RetrievalError(RAGError): pass
-class ProcessingError(RAGError): pass
-class GenerationError(RAGError): pass
-```
-
-**Benefits**:
-- Better debugging
-- Graceful fallbacks
-- Clear error messages in TUI
-
-## Performance Optimizations
-
-### 1. Database Optimizations
-
-- **FTS5 Tables**: Created for full-text search
-- **Connection Reuse**: Single persistent connection per database
-- **Query Optimization**: Pushed filtering to SQL level
-- **Batch Operations**: For embedding storage
-
-### 2. Document Processing
-
-- **Smart Deduplication**: Two-phase deduplication (within source, then cross-source)
-- **Efficient Ranking**: FlashRank integration with fallback
-- **Token Counting**: Tiktoken for accurate context sizing
-- **Chunking**: Configurable chunk size with overlap
-
-### 3. Resource Management
-
-- **Lazy Initialization**: Components load on-demand
-- **Memory Limits**: Configurable cache sizes
-- **Connection Cleanup**: Proper resource disposal
-- **Metrics Collection**: Optional performance monitoring
-
-## Migration Path
-
-### 1. Compatibility Layer
-
-Created compatibility wrappers for gradual migration:
-```python
-# Old API still works
-result = await enhanced_rag_pipeline(...)
-
-# But internally uses new system
-```
-
-### 2. Integration Helpers
-
-`integration.py` provides high-level interface:
-```python
-rag_service = RAGService(
-    media_db_path=...,
-    chachanotes_db_path=...,
-    llm_handler=...
-)
-```
-
-### 3. TUI Examples
-
-`tui_example.py` shows practical integration patterns for:
-- Search widgets
-- Event handlers
-- Streaming responses
-- Configuration
-
-## Testing Strategy
-
-### 1. Unit Tests
-- Configuration validation
-- Individual component testing
-- Mock dependencies
-
-### 2. Integration Tests
-- End-to-end RAG pipeline
-- Database interactions
-- Cache behavior
-
-### 3. Performance Tests
-- Benchmark vs old implementation
-- Memory usage profiling
-- Latency measurements
-
-## Metrics and Monitoring
-
-Built-in metrics collection:
-- Query latency
-- Cache hit rates
-- Error frequencies
-- Source distribution
-
-Access via:
-```python
-stats = rag_service.get_stats()
-```
-
-## Configuration Defaults
-
-Optimized defaults for single-user TUI:
-- `batch_size`: 32 (balanced for local processing)
-- `num_workers`: 4 (limited for single user)
-- `cache_ttl`: 3600 (1 hour)
-- `hybrid_alpha`: 0.5 (balanced search)
-- `max_context_length`: 4096 tokens
-
-## Known Limitations
-
-1. **Single User Only**: No multi-tenancy support
-2. **Local Only**: Designed for local databases
-3. **Memory Usage**: Caches can grow large with extensive use
-4. **GPU Support**: Limited, mainly CPU-optimized
-
-## Future Enhancements
-
-### Short Term
-1. Add more embedding model options
-2. Implement query expansion
-3. Add feedback loop for result improvement
-
-### Long Term
-1. Multi-modal search (images, audio)
-2. Advanced caching strategies
-3. Distributed search (if needed)
-4. Real-time index updates
-
-## Code Quality Improvements
-
-### From Original
-- **Reduced Complexity**: 1604 lines → ~400 lines per module
-- **Type Safety**: Full type annotations with protocols
-- **Error Handling**: Specific exceptions vs generic
-- **Resource Management**: Proper cleanup and context managers
-- **Code Duplication**: Eliminated repeated patterns
-
-### New Features
-- **Streaming Support**: Progressive response generation
-- **Metrics Collection**: Built-in performance monitoring
-- **Flexible Configuration**: TOML with validation
-- **Extensible Design**: Easy to add new sources/strategies
-
-## Deployment Considerations
-
-### For TUI Integration
-1. Add RAG config section to `config.toml`
-2. Initialize service during app startup
-3. Add UI controls for RAG mode
-4. Handle streaming responses in UI
-
-### Performance Tuning
-- Adjust `hybrid_alpha` based on data characteristics
-- Enable/disable reranking based on quality needs
-- Configure cache sizes based on available memory
-- Use GPU if available for embeddings
-
-## Conclusion
-
-The re-architecture successfully transforms a monolithic, hard-to-maintain module into a clean, efficient, and extensible system. Key improvements:
-
-1. **60% code reduction** through better organization
-2. **10x easier to test** with modular design
-3. **2-3x faster** for repeated queries with caching
-4. **100% type coverage** for better IDE support
-5. **Single-user optimized** for TUI performance
-
-The new architecture provides a solid foundation for future enhancements while immediately improving maintainability and performance.

-
-## Overview
-
-The RAG-Embeddings Integration ensures that the Retrieval-Augmented Generation (RAG) system uses actual production embeddings throughout the pipeline, with no mocking or placeholder implementations. This integration provides consistency, quality, and reliability for all embedding operations.
-
-### Key Principles
-- **No Mocking**: All embeddings are generated using the actual production service
-- **Provider Flexibility**: Supports multiple embedding providers (OpenAI, HuggingFace, Cohere, etc.)
-- **ChromaDB Integration**: Replaces ChromaDB's default embeddings with our production service
-- **Production Ready**: Full error handling, metrics, and monitoring
-
-## How It Works
-
-### 1. The Problem
-By default, ChromaDB uses its own embedding functions which may not align with your production embedding service. This can lead to:
-- Inconsistent embeddings between indexing and querying
-- Different quality levels between development and production
-- Inability to use custom or fine-tuned models
-- Lack of control over embedding generation
-
-### 2. The Solution
-Our integration provides a custom embedding function that ChromaDB uses for all operations:
-
-```mermaid
-graph TD
-    subgraph "Standard ChromaDB Flow"
-        A1[Document] --> B1[ChromaDB Default Embeddings]
-        B1 --> C1[Vector Store]
-        D1[Query] --> B1
-        B1 --> E1[Search Results]
-    end
-
-    subgraph "Our Integration Flow"
-        A2[Document] --> B2[ProductionEmbeddingFunction]

-        G2[Query] --> B2
-        B2 --> H2[Query Embeddings]
-        H2 --> I2[Search Results]
-    end
-
-    style B2 fill:#90EE90
-    style C2 fill:#90EE90
-    style D2 fill:#87CEEB
-```
-
-### 3. Step-by-Step Process
-
-#### Document Indexing
-1. **Document Input**: RAG system receives documents to index
-2. **ChromaDB Call**: ChromaDB's `add()` method is called with documents
-3. **Custom Embedding Function**: ChromaDB calls our `ProductionEmbeddingFunction`
-4. **Real Service Call**: Function calls `create_embeddings_batch()` from production service
-5. **Provider API**: Production service calls actual provider (OpenAI, HuggingFace, etc.)
-6. **Embeddings Return**: Real embeddings are returned to ChromaDB
-7. **Storage**: ChromaDB stores documents with real embeddings
-
-#### Query Processing
-1. **Query Input**: User submits a search query
-2. **ChromaDB Query**: ChromaDB's `query()` method is called
-3. **Query Embedding**: Same `ProductionEmbeddingFunction` generates query embedding
-4. **Vector Search**: ChromaDB performs similarity search with consistent embeddings
-5. **Results**: Relevant documents are retrieved with accurate similarity scores

-```
-
-## Implementation Details
-
-### 1. ProductionEmbeddingFunction
-
-This class implements ChromaDB's `EmbeddingFunction` interface but uses our production service:
-
-```python
-class ProductionEmbeddingFunction(EmbeddingFunction):
-    def __call__(self, input: Documents) -> Embeddings:
-        # Called by ChromaDB for any embedding operation
-        embeddings = create_embeddings_batch(
-            texts=input,
-            provider=self.provider,
-            model_id=self.model_id,
-            api_key=self.api_key
-        )
-        return embeddings.tolist()
-```
-
-**Key Points:**
-- Implements ChromaDB's required interface
-- Internally uses `create_embeddings_batch()` from production service
-- Handles both sync and async operations
-- Converts numpy arrays to lists for ChromaDB compatibility
-
-### 2. EnhancedVectorRetriever
-
-Manages vector storage and retrieval with production embeddings:
-
-```python
-class EnhancedVectorRetriever:
-    def __init__(self, ...):
-        # Create embedding function with production service
-        self.embedding_function = ProductionEmbeddingFunction(...)
-
-        # Initialize ChromaDB with our embedding function
-        self.collection = chroma_client.create_collection(
-            name=collection_name,
-            embedding_function=self.embedding_function  # Key: Use our function
-        )
-```
-
-**Key Features:**
-- Ensures all ChromaDB operations use production embeddings
-- Provides consistent interface for RAG operations
-- Tracks embedding provider in metadata
-- Handles filters and search parameters
-
-### 3. RAGEmbeddingsIntegration
-
-High-level integration manager:
-
-```python
-class RAGEmbeddingsIntegration:
-    def __init__(self, ...):
-        # Initialize embeddings service wrapper
-        self.embeddings_service = EmbeddingsServiceWrapper(...)
-
-    def create_vector_retriever(self, ...):
-        # Creates retriever with production embeddings
-        return EnhancedVectorRetriever(...)
-```
-
-**Responsibilities:**
-- Manages embedding service lifecycle
-- Creates configured retrievers
-- Provides direct embedding generation methods
-- Collects and reports metrics
-
-## Usage Guide
-
-### Basic Setup
-
-```python
-from tldw_Server_API.app.core.RAG.rag_embeddings_integration import (
-    create_rag_embeddings_integration,
-    RAGEmbeddingsIntegration
-)
-
-# Create integration
-integration = create_rag_embeddings_integration(
-    provider="openai",
-    model="text-embedding-3-small",
-    api_key="your-api-key"  # Optional, uses env var if not provided
-)
-```
-
-### Creating a Vector Retriever
-
-```python
-from pathlib import Path
-from tldw_Server_API.app.core.RAG.rag_service.types import DataSource
-
-# Create retriever with production embeddings
-retriever = integration.create_vector_retriever(
-    source=DataSource.MEDIA_DB,
-    chroma_path=Path("/path/to/chroma/storage"),
-    collection_name="my_documents"
-)
-```
-
-### Indexing Documents
-
-```python
-from tldw_Server_API.app.core.RAG.rag_service.types import Document
-
-# Create documents
-documents = [
-    Document(
-        id="doc1",
-        content="Your document content here",
-        metadata={"source": "file.pdf", "page": 1},
-        source=DataSource.MEDIA_DB,
-        score=0.0
-    )
-]
-
-# Store with production embeddings
-await retriever.embed_and_store(documents)
-```
-
-### Searching
-
-```python
-# Search using production embeddings
-results = await retriever.retrieve(
-    query="search query",
-    filters={"source": "file.pdf"},
-    top_k=5
-)
-
-for doc in results.documents:
-    print(f"Score: {doc.score:.3f}, Content: {doc.content[:100]}...")
-```
-
-### Direct Embedding Generation
-
-```python
-# Generate query embedding
-query_embedding = await integration.embed_query("What is machine learning?")
-
-# Generate document embeddings
-doc_embeddings = await integration.embed_documents([
-    "Document 1 content",
-    "Document 2 content"
-])
-```
-
-## Configuration
-
-### Environment Variables
-
-```bash
-# Embedding provider settings
-EMBEDDING_PROVIDER=openai
-EMBEDDING_MODEL=text-embedding-3-small
-

-```
-
-## Testing
-
-### Unit Testing
-
-```python
-def test_embedding_function():
-    """Test that embedding function uses real service."""
-    func = ProductionEmbeddingFunction(
-        provider="huggingface",
-        model_id="sentence-transformers/all-MiniLM-L6-v2"
-    )
-
-    # Generate embeddings
-    embeddings = func(["test document"])
-
-    # Verify real embeddings (not mocked)
-    assert len(embeddings) == 1
-    assert len(embeddings[0]) == 384  # MiniLM dimension
-    assert not all(e == 0 for e in embeddings[0])  # Not zeros
-```
-
-### Integration Testing
-
-```python
-async def test_end_to_end_flow():
-    """Test complete RAG flow with real embeddings."""
-    integration = create_rag_embeddings_integration(
-        provider="huggingface",
-        model="sentence-transformers/all-MiniLM-L6-v2"
-    )
-
-    retriever = integration.create_vector_retriever(...)
-
-    # Index documents
-    await retriever.embed_and_store(documents)
-
-    # Search
-    results = await retriever.retrieve("query")
-
-    # Verify results use real embeddings
-    assert results.metadata["embedding_provider"] == "huggingface"
-```
-
-### Verification Checklist
-
-- [ ] Embeddings have correct dimensions for the model
-- [ ] Different texts produce different embeddings
-- [ ] Embeddings are deterministic for same input
-- [ ] Search results are semantically relevant
-- [ ] No mock/fake embeddings in production logs
-- [ ] Metrics show actual API calls to providers
-
-## Troubleshooting
-
-### Common Issues
-
-#### 1. Import Errors
-```python
-ModuleNotFoundError: No module named 'prometheus_client'
-```
-**Solution**: Install required dependencies
-```bash
-pip install prometheus-client
-```
-
-#### 2. API Key Issues
-```python
-RuntimeError: API key not found for provider openai
-```
-**Solution**: Set API key in environment or pass directly
-```bash
-export OPENAI_API_KEY=your-key
-# or
-integration = create_rag_embeddings_integration(api_key="your-key")
-```
-
-#### 3. Dimension Mismatch
-```python
-ValueError: Embedding dimension mismatch: expected 1536, got 384
-```
-**Solution**: Ensure consistent model throughout pipeline
-- Check model name in initialization
-- Verify ChromaDB collection uses same model
-- Clear and rebuild index if model changed
-
-#### 4. ChromaDB Collection Conflicts
-```python
-ValueError: Collection already exists with different embedding function
-```
-**Solution**: Either use existing collection or delete and recreate
-```python
-# Option 1: Use existing
-collection = chroma_client.get_collection(name, embedding_function=func)
-
-# Option 2: Delete and recreate
-chroma_client.delete_collection(name)
-collection = chroma_client.create_collection(name, embedding_function=func)
-```
-
-### Performance Optimization
-
-#### Batch Processing
-```python
-# Process in batches for better performance
-batch_size = 100
-for i in range(0, len(documents), batch_size):
-    batch = documents[i:i + batch_size]
-    await retriever.embed_and_store(batch)
-```
-
-#### Connection Pooling
-```python
-# Reuse integration instance for multiple operations
-integration = create_rag_embeddings_integration(...)
-
-# Use same instance for all retrievers
-retriever1 = integration.create_vector_retriever(...)
-retriever2 = integration.create_vector_retriever(...)
-```
-
-#### Caching
-```python
-# Enable caching in integration
-integration = RAGEmbeddingsIntegration(
-    cache_embeddings=True  # Cache repeated embeddings
-)
-```
-
-### Monitoring
-
-#### Check Metrics
-```python
-metrics = integration.get_metrics()
-print(f"Total embeddings created: {metrics['total_texts_processed']}")
-print(f"Cache hit rate: {metrics['cache_hit_rate']:.2%}")
-print(f"Error rate: {metrics['error_rate']:.2%}")
-```
-
-#### Verify Provider Usage
-```python
-stats = retriever.get_embedding_stats()
-print(f"Using provider: {stats['embedding_provider']}")
-print(f"Model: {stats['embedding_model']}")
-print(f"Documents indexed: {stats['document_count']}")
-```
-
-## Best Practices
-
-1. **Consistent Models**: Use the same embedding model for indexing and querying
-2. **Error Handling**: Always wrap operations in try-catch blocks
-3. **Resource Management**: Use context managers or explicitly close integrations
-4. **Batch Operations**: Process documents in batches for efficiency
-5. **Monitor Metrics**: Track embedding generation performance and errors
-6. **Test Thoroughly**: Verify embeddings are real, not mocked
-7. **Document Provider**: Store embedding provider/model in metadata
-
-## Summary
-
-The RAG-Embeddings Integration ensures that:
-- All embeddings are generated using production services (no mocking)
-- ChromaDB uses our custom embedding function for all operations
-- The system supports multiple embedding providers
-- Embeddings are consistent between indexing and querying
-- Full metrics and monitoring are available
-- The integration is production-ready with proper error handling
-
-This architecture provides a robust, reliable, and consistent embedding pipeline for the RAG system.

-# Enhanced RAG Implementation Features
-
-This document describes the advanced RAG features implemented based on analysis of the external RAG pipeline from https://github.com/IlyaRice/RAG-Challenge-2.
-
-## Overview
-
-The enhanced RAG implementation adds several sophisticated features to improve retrieval quality and context understanding:
-
-1. **Enhanced Chunking with Character-Level Position Tracking**
-2. **Hierarchical Document Structure Preservation**
-3. **Parent Document Retrieval**
-4. **Advanced Text Processing**
-5. **Table Serialization**
-
-## 1. Enhanced Chunking with Character-Level Position Tracking
-
-### Features
-- Accurate character-level position tracking (`start_char`, `end_char`)
-- Word count tracking per chunk
-- Hierarchical chunk relationships (parent-child)
-- Structure-aware chunking that respects document boundaries
-
-### Implementation
-```python
-from tldw_chatbook.RAG_Search.enhanced_chunking_service import EnhancedChunkingService
-
-service = EnhancedChunkingService()
-chunks = service.chunk_text_with_structure(
-    content,
-    chunk_size=400,
-    chunk_overlap=100,
-    method="hierarchical",  # or "structural"
-    preserve_structure=True,
-    clean_artifacts=True,
-    serialize_tables=True
-)
-```
-
-### Benefits
-- Precise citation generation
-- Better chunk boundary detection
-- Maintains document structure integrity
-
-## 2. Hierarchical Document Structure Preservation
-
-### Features
-- Identifies document elements (headers, sections, lists, tables, etc.)
-- Maintains parent-child relationships between chunks
-- Preserves hierarchical levels (h1, h2, h3, etc.)
-- Respects structural boundaries when chunking
-
-### Chunk Types
-- `HEADER` - Document headers
-- `SECTION` - Main content sections
-- `LIST` - Bulleted or numbered lists
-- `TABLE` - Tabular data
-- `CODE_BLOCK` - Code snippets
-- `QUOTE` - Quoted text
-- `FOOTNOTE` - Footnotes and references
-
-### Implementation
-```python
-# Each chunk includes structural metadata
-chunk = StructuredChunk(
-    text="chunk content",
-    chunk_type=ChunkType.SECTION,
-    level=2,  # Hierarchical level
-    parent_index=0,  # Reference to parent chunk
-    children_indices=[3, 4, 5]  # Child chunks
-)
-```
-
-## 3. Parent Document Retrieval
-
-### Features
-- Creates smaller chunks for precise retrieval
-- Maintains larger parent chunks for context
-- Automatic context expansion during search
-- Configurable parent size multiplier
-
-### Implementation
-```python
-from tldw_chatbook.RAG_Search.simplified.enhanced_rag_service import EnhancedRAGService
-
-service = EnhancedRAGService(enable_parent_retrieval=True)
-
-# Index with parent chunks
-result = await service.index_document_with_parents(
-    doc_id="doc_001",
-    content=content,
-    parent_size_multiplier=3  # Parent chunks 3x larger
-)
-
-# Search with automatic context expansion
-results = await service.search_with_context_expansion(
-    query="your search query",
-    expand_to_parent=True
-)
-```
-
-### Benefits
-- Better context for LLM understanding
-- Maintains retrieval precision
-- Reduces hallucination by providing more context
-
-## 4. Advanced Text Processing
-
-### PDF Artifact Cleaning
-Automatically cleans common PDF parsing artifacts:
-- Command replacements (`/period` → `.`, `/comma` → `,`)
-- Glyph removal (`glyph<123>` → ``)
-- Character normalization (`/A.cap` → `A`)
-
-### Implementation
-```python
-parser = DocumentStructureParser()
-cleaned_text, corrections = parser.clean_text(pdf_text)
-```
-
-### Structure-Aware Formatting
-- Preserves document hierarchy
-- Maintains list and table relationships
-- Handles footnotes and references correctly
-
-## 5. Table Serialization
-
-### Features
-- Multiple serialization methods (entities, sentences, hybrid)
-- Preserves table structure and relationships
-- Creates searchable representations of tabular data
-
-### Serialization Methods
-
-#### Entity Blocks
-Each table row becomes a structured entity:
-```
-Row 1; Product: Laptop; Q1 Sales: 1000; Q2 Sales: 1200; Growth: 20%
-```
-
-#### Natural Language Sentences
-Tables converted to descriptive sentences:
-```
-This table contains 3 rows and 4 columns with headers: Product, Q1 Sales, Q2 Sales, Growth.
-In row 1, Product is Laptop, Q1 Sales is 1000, Q2 Sales is 1200, Growth is 20%.
-```
-
-### Implementation
-```python
-from tldw_chatbook.RAG_Search.table_serializer import serialize_table
-
-result = serialize_table(
-    table_text,
-    format=TableFormat.MARKDOWN,
-    method="hybrid"  # Uses both entities and sentences
-)
-```
-
-## Usage Examples
-
-### Basic Usage
-```python
-# Create enhanced RAG service
-from tldw_chatbook.RAG_Search.simplified.enhanced_rag_service import create_enhanced_rag_service
-
-service = create_enhanced_rag_service(
-    embedding_model="all-MiniLM-L6-v2",
-    enable_parent_retrieval=True
-)
-
-# Index document with all enhancements
-await service.index_document_with_parents(
-    doc_id="doc_001",
-    content=document_text,
-    title="Document Title",
-    use_structural_chunking=True
-)
-
-# Search with context expansion
-results = await service.search_with_context_expansion(
-    query="your query",
-    top_k=5,
-    expand_to_parent=True
-)
-```
-
-### Batch Processing
-```python
-# Process multiple documents
-results = await service.index_batch_with_parents(
-    documents=[
-        {"id": "doc1", "content": "...", "title": "..."},
-        {"id": "doc2", "content": "...", "title": "..."}
-    ],
-    use_structural_chunking=True
-)
-```
-
-## Configuration Options
-
-### Enhanced Chunking
-- `chunk_size` - Target size for retrieval chunks
-- `chunk_overlap` - Overlap between chunks
-- `parent_size_multiplier` - How much larger parent chunks are
-- `preserve_structure` - Whether to maintain document structure
-- `clean_artifacts` - Whether to clean PDF artifacts
-- `serialize_tables` - Whether to serialize tables
-
-### Search Options
-- `expand_to_parent` - Automatically expand to parent context
-- `include_citations` - Include citation information
-- `search_type` - "semantic", "keyword", or "hybrid"
-
-## Performance Considerations
-
-1. **Memory Usage**: Parent chunks increase memory usage by ~3x
-2. **Indexing Time**: Enhanced processing adds 20-30% overhead
-3. **Search Performance**: Context expansion has minimal impact
-4. **Storage**: Requires additional metadata storage
-
-## Migration Guide
-
-### From Basic to Enhanced RAG
-
-1. Replace imports:
-```python
-# Old
-from tldw_chatbook.RAG_Search.simplified.rag_service import RAGService
-
-# New
-from tldw_chatbook.RAG_Search.simplified.enhanced_rag_service import EnhancedRAGService
-```
-
-2. Update service creation:
-```python
-# Old
-service = RAGService(config)
-
-# New
-service = EnhancedRAGService(config, enable_parent_retrieval=True)
-```
-
-3. Use enhanced methods:
-```python
-# Old
-await service.index_document(...)
-
-# New
-await service.index_document_with_parents(...)
-```
-
-## Testing
-
-Run the test script to verify functionality:
-```bash
-python test_enhanced_rag.py
-```
-
-This will test:
-- Enhanced chunking with structure preservation
-- Parent document retrieval
-- Table serialization
-- PDF artifact cleaning
-- Context expansion during search

-# RAG Search Enhancements Documentation
-
-This document provides comprehensive documentation for the enhanced RAG (Retrieval-Augmented Generation) search components added to the tldw_server project.
-
-## Overview
-
-The RAG enhancements introduce advanced capabilities for improving search quality, performance, and flexibility. These components work together to provide a more intelligent and efficient search experience.
-
-## Components
-
-### 1. Advanced Query Expansion (`advanced_query_expansion.py`)
-
-Expands user queries using multiple strategies to improve recall and find relevant documents that might use different terminology.
-
-#### Features
-- **Multiple Expansion Strategies**:
-  - `SEMANTIC`: Find semantically similar terms using word embeddings
-  - `LINGUISTIC`: Apply linguistic rules (synonyms, stemming, lemmatization)
-  - `ENTITY`: Extract and expand named entities
-  - `ACRONYM`: Expand/contract acronyms (e.g., "ML" ↔ "Machine Learning")
-  - `DOMAIN`: Add domain-specific related terms
-
-#### Usage
-```python
-from tldw_Server_API.app.core.RAG.RAG_Search.advanced_query_expansion import (
-    AdvancedQueryExpander, ExpansionConfig, ExpansionStrategy
-)
-
-# Configure expander
-config = ExpansionConfig(
-    strategies=[ExpansionStrategy.LINGUISTIC, ExpansionStrategy.ACRONYM],
-    max_expansions_per_strategy=3,
-    total_max_expansions=10
-)
-
-expander = AdvancedQueryExpander(config)
-expansions = await expander.expand_query("What is ML?")
-# Returns: ["What is ML?", "What is Machine Learning?", "What is machine learning?", ...]
-```
-
-#### Configuration
-- `strategies`: List of strategies to use
-- `max_expansions_per_strategy`: Max expansions per strategy (default: 5)

-
-### 2. Advanced Reranking (`advanced_reranker.py`)
-
-Reranks search results using sophisticated algorithms to improve precision and relevance.
-
-#### Reranking Strategies
-
-1. **Cross-Encoder**: Uses a BERT-based model to score query-document pairs
-2. **LLM Scoring**: Uses LLM to score relevance (requires API key)
-3. **Diversity**: Promotes diverse results using MMR algorithm
-4. **Multi-Criteria**: Combines multiple scoring factors
-5. **Hybrid**: Combines multiple strategies with weighted voting
-
-#### Usage
-```python
-from tldw_Server_API.app.core.RAG.RAG_Search.advanced_reranker import (
-    create_reranker, RerankingStrategy
-)
-
-# Create reranker
-reranker = create_reranker(
-    RerankingStrategy.HYBRID,
-    top_k=10,
-    config={"diversity_weight": 0.3}
-)
-
-# Rerank results
-reranked = await reranker.rerank(
-    query="machine learning applications",
-    documents=[{"content": "...", "metadata": {...}}, ...]
-)
-```
-
-#### Key Features

-
-#### Cache Strategies
-
-1. **LRU Cache**: Fast in-memory cache with TTL support
-2. **Semantic Cache**: Finds cached results for semantically similar queries
-3. **Tiered Cache**: Two-tier cache with memory and disk levels
-4. **Adaptive Cache**: Adjusts caching based on access patterns
-
-#### Usage
-```python
-from tldw_Server_API.app.core.RAG.RAG_Search.enhanced_cache import (
-    CacheManager, LRUCacheStrategy, SemanticCacheStrategy
-)
-
-# Create cache manager with multiple strategies
-cache_manager = CacheManager([
-    LRUCacheStrategy(max_size=1000, ttl=3600),
-    SemanticCacheStrategy(similarity_threshold=0.9)
-])
-
-# Cache operations
-await cache_manager.set("query_key", result_data, query="user query")
-cached = await cache_manager.get("query_key")
-
-# Get cache stats
-stats = cache_manager.get_stats()
-```

-)
-
-# Create chunker
-chunker = create_chunker(
-    ChunkingStrategy.ADAPTIVE,
-    chunk_size=512,
-    overlap=50
-)
-
-# Chunk document
-chunks = chunker.chunk(document_text)
-for chunk in chunks:
-    print(f"Chunk {chunk.metadata.chunk_id}: {chunk.text[:50]}...")
-    print(f"  Type: {chunk.metadata.chunk_type}")
-    print(f"  Size: {chunk.metadata.char_count} chars")
-```
-
-#### Features
-- Metadata-rich chunks (position, type, hierarchy)
-- Configurable overlap for context preservation

-
-# Run from module directly
-python app/core/RAG/RAG_Search/integration_test.py
-```
-
-## Integration with Existing System
-
-### 1. With RAG Service
-The enhanced components integrate seamlessly with the existing RAG service:
-
-```python
-from tldw_Server_API.app.core.RAG.rag_service.integration import RAGService
-from tldw_Server_API.app.core.RAG.RAG_Search.advanced_query_expansion import AdvancedQueryExpander
-from tldw_Server_API.app.core.RAG.RAG_Search.advanced_reranker import create_reranker
-
-# Enhance RAG service
-rag_service = RAGService(config=config)
-rag_service.query_expander = AdvancedQueryExpander()
-rag_service.reranker = create_reranker(RerankingStrategy.HYBRID)
-```
-
-### 2. With API Endpoints
-The components are used in the `/retrieval` endpoints:
-
-- `/retrieval/search`: Uses query expansion and reranking
-- `/retrieval/agent`: Full pipeline with all enhancements
-
-### 3. With Existing Databases
-Works with existing SQLite and ChromaDB databases without modification.
-
-## Configuration Best Practices
-
-### For Development
-```python
-# Fast iteration, lower quality
-config = {
-    "query_expansion": {
-        "strategies": ["LINGUISTIC"],  # Fast strategies only
-        "max_expansions": 5
-    },
-    "reranking": {
-        "strategy": "DIVERSITY",  # No external API calls
-        "top_k": 10
-    },
-    "caching": {
-        "strategies": ["LRU"],  # Simple caching
-        "size": 100
-    }
-}
-```
-
-### For Production
-```python
-# High quality, with caching for performance
-config = {
-    "query_expansion": {
-        "strategies": ["SEMANTIC", "LINGUISTIC", "ACRONYM", "DOMAIN"],
-        "max_expansions": 20,
-        "enable_caching": True
-    },
-    "reranking": {
-        "strategy": "HYBRID",  # Best quality
-        "top_k": 20,
-        "diversity_weight": 0.3

-
-## Performance Considerations
-
-### Query Expansion
-- Semantic expansion requires embeddings (adds ~50-100ms)
-- Linguistic expansion is fast (<10ms)
-- Cache hit rate typically 40-60% for repeated queries
-
-### Reranking
-- Cross-encoder: ~100-200ms for 20 documents
-- LLM scoring: ~500-2000ms depending on provider
-- Diversity/Multi-criteria: <50ms
-
-### Caching
-- LRU cache: <1ms lookup
-- Semantic cache: ~50ms (embedding computation)
-- Tiered cache: Memory <1ms, Disk ~10-50ms
-
-### Chunking
-- Throughput: ~1-5 MB/s depending on strategy
-- Adaptive chunking: ~2x slower than fixed-size
-- Structural chunking: Fastest for structured documents
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Import Errors**
-   ```python
-   # Ensure PYTHONPATH includes project root
-   export PYTHONPATH=/path/to/tldw_server:$PYTHONPATH
-   ```
-
-2. **Semantic Features Not Working**
-   - Check if sentence-transformers is installed
-   - Verify model downloads completed
-   - Check available disk space for models
-
-3. **Performance Issues**
-   - Monitor with performance_monitor
-   - Check cache hit rates
-   - Reduce expansion strategies
-   - Use simpler reranking strategies
-
-4. **Memory Usage**
-   - Reduce cache sizes
-   - Use disk-based caching
-   - Limit batch sizes
-
-## Future Enhancements
-
-1. **Query Expansion**
-   - User-specific expansion learning
-   - Multi-language support
-   - Query intent detection
-
-2. **Reranking**
-   - Fine-tuned ranking models
-   - User preference learning
-   - Real-time feedback incorporation
-
-3. **Caching**
-   - Distributed caching support
-   - Predictive cache warming
-   - Cache compression
-
-4. **Performance**
-   - GPU acceleration for embeddings
-   - Async batch processing
-   - Query planning optimization
-

-# Archived RAG Implementations
-
-This folder contains deprecated RAG implementations that have been consolidated into the main `/app/core/RAG/rag_service/` implementation.
-
-## Archived Contents
-
-### RAG_Search/
-The original multi-implementation RAG module containing:
-- **simplified/** - Three different RAG service implementations (RAGService, EnhancedRAGService, EnhancedRAGServiceV2)
-- **pipeline_*.py** - Functional programming pipeline approach
-- Various chunking, reranking, and optimization modules
-
-### Documentation Files
-- **RAG-REPORT2.md** - Original re-architecture report for single-user TUI
-- **RAG_EMBEDDINGS_INTEGRATION_GUIDE.md** - Old embeddings integration guide
-
-### Utility Files
-- **import_fixer.py** - Script used during migration from tldw_chatbook to tldw_Server_API
-- **rag_embeddings_integration.py** - Old embeddings integration (needs updating if restored)
-
-## Status
-
-**⚠️ DEPRECATED - DO NOT USE**
-
-All functionality from these implementations has been consolidated into the main RAG service at `/app/core/RAG/rag_service/` with the following improvements:
-
-1. **Unified Architecture** - Single implementation instead of 4
-2. **Feature Complete** - All features available through configuration
-3. **Better Testing** - Comprehensive test coverage
-4. **Improved Performance** - Connection pooling and optimizations
-
-## Migration
-
-If you need to reference old code:
-1. Look here for implementation details
-2. Use the new consolidated service for all new work
-3. Features are now available via configuration flags
-
-## Files Still Referencing Archived Code
-
-The following files may need updating as they reference the archived implementations:
-- `/app/core/Evaluations/rag_evaluator.py`
-- `/tests/RAG/test_rag_embeddings_integration.py`
-
-These should be updated to use the new consolidated implementation at `/app/core/RAG/rag_service/`
-

+Grafana Dashboards for tldw_server
+
+Overview
+- This folder contains an example Grafana dashboard JSON for visualizing the LLM Gateway metrics exposed at `/metrics`.
+- The dashboard targets the internal Prometheus-style metrics emitted by `tldw_Server_API.app.core.Metrics.metrics_manager` and the HTTP middleware.
+
+Prometheus Scrape (example)
+Add a scrape job pointing to your server (adjust host/port):
+
+  scrape_configs:
+    - job_name: 'tldw_server'
+      metrics_path: /metrics
+      static_configs:
+        - targets: ['127.0.0.1:8000']
+
+Importing the Dashboard
+1) In Grafana: Dashboards -> New -> Import.
+2) Upload `llm_gateway_dashboard.json`.
+3) Set the Prometheus datasource when prompted.
+
+Variables
+- DS_PROMETHEUS: Prometheus datasource selector (choose your Prometheus instance).
+- endpoint: HTTP endpoint label (defaults to `/api/v1/chat/completions`).
+- method: HTTP method label (defaults to `POST`).
+- provider: LLM provider label (e.g., `openai`).
+- model: LLM model label (e.g., `gpt-4o-mini`).

+Notes
+- If you run the server in mock mode for benchmarking (`CHAT_FORCE_MOCK=1`), the upstream LLM panels still work since metrics are recorded by the gateway (decorators and usage tracker).
+- The HTTP latency panels are driven by `http_request_duration_seconds_bucket`. LLM latency panels are driven by `llm_request_duration_seconds_bucket`.

+LLM Gateway Benchmark Scripts
+
+Overview
+- `llm_gateway_bench.py` is a minimal async load generator for the Chat API (`/api/v1/chat/completions`).
+- It sweeps concurrency levels and reports latency percentiles, error rates, and streaming TTFT.
+
+Recommended Server Settings (for safe local benchmarking)
+- Quick start (recommended):
+
+  make server-up-dev HOST=127.0.0.1 PORT=8000 API_KEY=dev-key-123
+
+  This starts uvicorn with:
+  - `AUTH_MODE=single_user`
+  - `SINGLE_USER_API_KEY=$API_KEY`
+  - `DEFAULT_LLM_PROVIDER=openai`
+  - `CHAT_FORCE_MOCK=1` (no upstream calls)
+  - `STREAMS_UNIFIED=1` (enables SSE metrics)
+
+- Manual alternative:
+
+  AUTH_MODE=single_user \
+  SINGLE_USER_API_KEY=dev-key-123 \
+  CHAT_FORCE_MOCK=1 \
+  DEFAULT_LLM_PROVIDER=openai \
+  STREAMS_UNIFIED=1 \
+  python -m uvicorn tldw_Server_API.app.main:app --host 127.0.0.1 --port 8000 --reload
+
+  Notes:
+  - `CHAT_FORCE_MOCK=1` avoids hitting real upstream providers; responses are mocked and fast.
+  - In multi-user mode, supply a Bearer token instead of `X-API-KEY`.
+
+Examples
+- Non-streaming, 1/2/4/8 concurrency for 20s each:
+
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+    --base-url http://127.0.0.1:8000 \
+    --path /api/v1/chat/completions \
+    --api-key "$SINGLE_USER_API_KEY" \
+    --concurrency 1 2 4 8 \
+    --duration 20
+
+- Streaming with concurrency=16 for 30s:
+
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+    --stream \
+    --concurrency 16 \
+    --duration 30 \
+    --api-key "$SINGLE_USER_API_KEY"
+
+- Stop on error-rate > 5% or p99 > 5s:
+
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+    --concurrency 1 2 4 8 16 32 \
+    --duration 20 \
+    --max-error-rate 0.05 \
+    --latency-p99-sla-ms 5000
+
+What It Measures
+- Per step: total, successes/failures, RPS, p50/p90/p95/p99 (ms)
+- If `--stream`: TTFT (p50/p95) in ms
+- Optional server-side metrics deltas from `/metrics` (Prometheus):
+  - `http_requests_total{endpoint="/api/v1/chat/completions",status="..."}` by status
+  - Use `--metrics-url` to point to a different metrics endpoint
+
+Tips
+- Increase `--prompt-bytes` to simulate larger inputs.
+- Use `--provider openai --model gpt-4o-mini` with `CHAT_FORCE_MOCK=1` for consistent, fast results.
+- Optionally export to JSON with `--out results.json`.
+
+Locust (Open-Loop RPS)
+- File: `Helper_Scripts/benchmarks/locustfile.py`
+- Closed-loop (headless):
+
+  locust -f Helper_Scripts/benchmarks/locustfile.py --host http://127.0.0.1:8000 \
+    --headless -u 50 -r 10 -t 2m
+
+- Approximate open-loop RPS plan via env:
+
+  TLDW_RPS_PLAN="10:30,20:30,40:60,20:30,10:30" \
+  TLDW_TASKS_PER_USER_PER_SEC=1 \
+  locust -f Helper_Scripts/benchmarks/locustfile.py --host http://127.0.0.1:8000 --headless -t 3m
+
+- Optional env vars:
+  - `TLDW_BENCH_PATH` (default `/api/v1/chat/completions`)
+  - `TLDW_BENCH_PROVIDER` (default `openai`)
+  - `TLDW_BENCH_MODEL` (default `gpt-4o-mini`)
+  - `TLDW_BENCH_STREAM` (`1|true|yes|on` to enable streaming)
+  - `TLDW_BENCH_PROMPT_BYTES` (default 256)
+  - `SINGLE_USER_API_KEY` or `TLDW_BENCH_BEARER_TOKEN`
+  - `TLDW_TASKS_PER_USER_PER_SEC` (default 1; used with RPS plan)
+
+Notes
+- Streaming in Locust: total request time includes consuming the stream; a synthetic TTFT metric is emitted as `request_type=TTFT`, `name=chat:stream_ttft`.
+
+Monitoring Stack (Prometheus + Grafana)
+- Compose files: `Dockerfiles/Monitoring/`
+- Start stack:
+
+  docker compose -f Dockerfiles/Monitoring/docker-compose.monitoring.yml up -d
+
+- Prometheus scrapes `host.docker.internal:8000/metrics` by default (adjust `Dockerfiles/Monitoring/prometheus.yml`).
+- Grafana at http://localhost:3000 (admin/admin). The `LLM Gateway` dashboard is auto-provisioned from `Docs/Monitoring/Grafana_Dashboards/`.
+- To enable SSE panels (enqueue→yield), set on the server: `STREAMS_UNIFIED=1`.
+ - Linux note: if `host-gateway` is unsupported, change the Prometheus target to your host IP (e.g., `172.17.0.1:8000`).
+
+One‑Command Full Run
+- Start monitoring + run both sweeps (non-stream and stream) and print links:
+
+  make bench-full BASE_URL=http://127.0.0.1:8000 API_KEY=$SINGLE_USER_API_KEY \
+    FULL_CONCURRENCY="1 2 4 8" FULL_STREAM_CONCURRENCY="4 8 16" FULL_DURATION=20
+
+  Results are saved to `.benchmarks/bench_nonstream.json` and `.benchmarks/bench_stream.json`. Open Grafana at:
+  - http://localhost:3000/d/tldw-llm-gateway
+  - Login: admin / admin
+  - Tip: ensure the server runs with `STREAMS_UNIFIED=1` for SSE metrics.
+
+Make Targets (summary)
+- `server-up-dev`        — run uvicorn in mock mode with SSE metrics enabled
+- `monitoring-up`        — start Prometheus (9090) + Grafana (3000)
+- `monitoring-down`      — stop monitoring stack
+- `monitoring-logs`      — tail monitoring logs
+- `bench-sweep`          — non-stream concurrency sweep (writes `.benchmarks/bench_nonstream.json`)
+- `bench-stream`         — streaming sweep (writes `.benchmarks/bench_stream.json`)
+- `bench-rps`            — Locust RPS plan (open-loop approx)
+- `bench-full`           — monitoring-up + both sweeps + helpful links

+llm_gateway_bench.py
+
+Purpose:
+- Benchmark the tldw_server Chat API (/api/v1/chat/completions) for throughput and latency.
+- Sweep concurrency, measure p50/p90/p95/p99 latency, error rate, and basic streaming timings (TTFT).
+- Avoids external provider cost/limits when server runs with CHAT_FORCE_MOCK=1 (recommended).
+
+Usage (examples):
+
+  # Non-streaming, concurrency sweep 1,2,4,8 for 20s each (single-user API key)
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+      --base-url http://127.0.0.1:8000 \
+      --path /api/v1/chat/completions \
+      --api-key "$SINGLE_USER_API_KEY" \
+      --concurrency 1 2 4 8 \
+      --duration 20
+
+  # Streaming benchmark with bearer token (multi-user) and fixed overlap = 16
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+      --stream \
+      --concurrency 16 \
+      --duration 30 \
+      --bearer "$JWT_TOKEN"
+
+  # Ramp until error-rate > 5% or p99 > 5s
+  python Helper_Scripts/benchmarks/llm_gateway_bench.py \
+      --concurrency 1 2 4 8 16 32 \
+      --duration 20 \
+      --max-error-rate 0.05 \
+      --latency-p99-sla-ms 5000
+
+Notes:
+- To avoid hitting real providers, run the server with: CHAT_FORCE_MOCK=1 (and optionally TEST_MODE=1).
+- Provider/model can be set via args. Defaults aim for mock OpenAI-compatible flow.

 - Purpose: Unified client interface for commercial and local LLM providers used by the Chat API and internal services. Normalizes requests/responses to OpenAI-compatible shapes and standardizes streaming (SSE) and error handling.
 - Capabilities:
-  - Providers (commercial): OpenAI, Anthropic, Cohere, DeepSeek, Google (Gemini), Qwen, Groq, HuggingFace (OpenAI-compatible), Mistral, OpenRouter, Moonshot, Z.AI, Bedrock (via compatible endpoint).
+  - Providers (commercial): OpenAI, Anthropic, Cohere, DeepSeek, Google (Gemini), Qwen, Groq, HuggingFace (OpenAI-compatible), Mistral, OpenRouter, Moonshot, Z.AI, Bedrock (OpenAI-compatible).
   - Providers (local): local-llm, llama.cpp, Kobold, Oobabooga, TabbyAPI, vLLM, Aphrodite, Ollama, custom OpenAI-compatible gateways.
   - OpenAI-compatible chat semantics, tools/tool_choice passthrough where supported.
   - Streaming normalization to SSE frames; non-stream returns OpenAI-like dicts.

+# Realtime Voice Latency PRD
+
+Owner: Core Voice & API Team  
+Status: Draft (v0.1)
+
+## Overview
+
+Elevate the realtime voice experience (STT → LLM → TTS) to deliver natural, interruption‑friendly conversations with sub‑second voice‑to‑voice latency. Build on existing unified streaming STT, Kokoro streaming TTS, and OpenAI‑compatible APIs. Introduce precise turn detection, structured LLM streaming, low‑overhead audio transport options, and actionable end‑to‑end latency metrics.
+
+## Goals
+
+- Voice‑to‑voice latency (user stops speaking → first audible TTS): p50 ≤ 1.0s, p90 ≤ 1.8s.
+- STT final transcript latency (end‑of‑speech → final text): p50 ≤ 600ms.
+- TTS time‑to‑first‑byte (TTFB): p50 ≤ 250ms.
+- Structured LLM streaming: speakable text to TTS immediately; code blocks and links to UI in parallel.
+- Add reliable, lightweight metrics and a measurement harness.
+
+## Non‑Goals
+
+- Replacing existing RAG or LLM provider systems.
+- Forcing WebRTC in all deployments (optional Phase 3 only).
+- Vendor‑specific autoscaling mechanics (remain self‑host first).
+
+## Personas & Use Cases
+
+- Developers embedding voice agents in web apps who need:
+  - Fast and reliable end‑of‑utterance detection with interruption handling.
+  - Low TTS TTFB and smooth, continuous playback.
+  - Structured results where “speakable” text is voiced and code/links render in UI.
+
+## Success Metrics
+
+- p50/p90 voice‑to‑voice latency meets targets above.
+- <1% stream errors; 0 underruns in happy path.
+- Backwards compatible APIs (no breaking changes to current REST).
+
+## Scope & Phasing
+
+### Phase 1: Core Latency + Metrics (Required)
+- VAD/turn detection in streaming STT to trigger fast finalization.
+- TTS TTFB + STT finalization latency metrics; compute voice‑to‑voice.
+- PCM streaming option (lowest overhead) documented end‑to‑end.
+- Phoneme/lexicon overrides for consistent pronunciation of brand/technical terms.
+
+### Phase 2: Structured Streaming + WS TTS (Optional but Recommended)
+- Streaming JSON parser: stream “spoke_response” to TTS; route code blocks/links to UI channel.
+- WebSocket TTS endpoint for ultra‑low‑overhead PCM16 streaming.
+
+### Phase 3: WebRTC Egress (Optional)
+- Add a minimal WebRTC transport for browser playback where ultra‑low latency is required.
+
+## Reference Setup
+
+- Hardware/OS: 8‑core CPU, optional NVIDIA GPU (if Parakeet GPU path used); macOS 14 or Ubuntu 22.04
+- Runtime: Python 3.11, ffmpeg ≥ 6.0, `av` ≥ 11.0.0, optional `espeak-ng` (phonemizer backend), optional `pyannote`
+- Network: Localhost loopback during measurement; avoid WAN variability
+- Test audio: 10 s of 16 kHz float32 speech, single speaker, 250 ms trailing silence
+- Browser client (when applicable): latest Chrome/Edge/Firefox on same machine
+
+## Functional Requirements
+
+### STT Turn Detection
+- Add Silero VAD‑based turn detection to the unified streaming STT path.
+- Emit “commit” when end‑of‑speech is detected to finalize transcripts promptly.
+- Expose safe server defaults and client‑configurable tunables (threshold, min silence, stop secs).
+
+### TTS PCM Streaming
+- Support `response_format=pcm` through `/api/v1/audio/speech` and document as recommended for ultra‑low latency clients.
+- Keep MP3/Opus/AAC/FLAC for compatibility.
+
+REST PCM details:
+- Response header `Content-Type: audio/L16; rate=; channels=`; default `rate=24000`, `channels=1`.
+- Include `X-Audio-Sample-Rate: ` header.
+- Negotiation: default to provider/sample pipeline rate; optional `target_sample_rate` honored when supported.
+- Example curl: `-d '{"model":"tts-1","input":"Hello","voice":"alloy","response_format":"pcm","stream":true}'`
+- Example client: Web Audio API or Python playback snippet will be included in docs.
+
+### Phoneme/Lexicon Overrides
+- Optional phoneme mapping (config‑driven) to stabilize pronunciation of product names and domain terms.
+- Provider‑aware behavior (e.g., Kokoro ONNX/PyTorch; espeak/IPA support where applicable).
+
+### Structured LLM Streaming
+- Add a streaming JSON parser to split:
+  - `spoke_response` → stream chars immediately to TTS.
+  - `code_blocks` and `links` → deliver to UI channel as soon as arrays complete (with optional async link validation).
+- Make structured mode opt‑in (per request or model) to maintain backwards compatibility.
+
+Schema and examples (opt‑in mode):
+- Request flag: `structured_streaming: true` (per API call) or model‑level default
+- Server stream examples:
+  - `{ "type": "spoke_response", "text": "Great question..." }`
+  - `{ "type": "code_block", "lang": "python", "text": "print('hello')" }`
+  - `{ "type": "links", "items": [{"title": "Docs", "url": "https://..."}] }`
+Interaction with OpenAI compatible `/chat/completions`:
+- When enabled, server emits structured JSON chunks on the stream; speakable text is forwarded to TTS immediately; non‑speakable metadata is routed to the UI channel.
+
+### WebSocket TTS Endpoint (Optional)
+- New WS endpoint `/api/v1/audio/stream/tts` that accepts prompt frames and streams PCM16 bytes continuously with backpressure handling.
+
+WebSocket TTS API details:
+- Auth/Quotas: mirror STT WS. Support API key/JWT, endpoint allowlist checks, standardized close codes on quota.
+- Client → Server frames: `{type:"prompt", text, voice?, speed?, format?:"pcm"}`; optional `request_id`.
+- Server → Client frames: binary PCM16 audio frames (20–40 ms) with bounded queue; error frames as `{type:"error", "message": "..."}`.
+- Backpressure: drop or throttle when the queue exceeds limit; increment `audio_stream_underruns_total` and emit warning status.
+
+## Non‑Functional Requirements
+
+- Low overhead: avoid heavy per‑chunk work; keep encoders warmed.
+- Robustness: consistent behavior with disconnects, slow readers, and quotas.
+- Observability: gated logs; metrics first for timing paths.
+
+## Architecture & Components
+
+Key touchpoints:
+- STT WS handler: `tldw_Server_API/app/api/v1/endpoints/audio.py:1209` (stream/transcribe)
+- Unified streaming STT: `tldw_Server_API/app/core/Ingestion_Media_Processing/Audio/Audio_Streaming_Unified.py`
+- TTS REST endpoint: `tldw_Server_API/app/api/v1/endpoints/audio.py:268` (/audio/speech)
+- Kokoro adapter streaming path: `tldw_Server_API/app/core/TTS/adapters/kokoro_adapter.py`
+- Streaming encoder: `tldw_Server_API/app/core/TTS/streaming_audio_writer.py`
+- TTS orchestrator: `tldw_Server_API/app/core/TTS/tts_service_v2.py`
+
+Design changes:
+- Introduce VAD in Unified STT pipeline; on VAD end → finalize chunk with Parakeet.
+- Track event timestamps for end‑of‑speech, final transcript emission, TTS start, and first audio chunk write.
+- Add PCM passthrough branch in TTS streaming for minimal overhead; preserve encoded formats via `StreamingAudioWriter`.
+- Add phoneme pre‑processing hook in Kokoro adapter with config‑based mapping.
+- Add optional WS TTS service that streams PCM16 frames directly.
+
+## API Changes
+
+REST (existing): `/api/v1/audio/speech`
+- Support `response_format=pcm` (documented default for low‑latency clients).
+
+WebSocket (existing): `/api/v1/audio/stream/transcribe`
+- Accept optional client config to tune VAD/turn parameters (server defaults remain authoritative).
+- Emit final transcripts promptly at turn end.
+
+WebSocket (new, optional): `/api/v1/audio/stream/tts`
+- Client → Server (text frames): `{type:"prompt", text, voice?, speed?, format?:"pcm"}`
+- Server → Client (binary): PCM16 frames. Error frames as `{type:"error", message}`.
+
+Structured LLM streaming (optional flag)
+- When enabled, server parses JSON streams and routes fields: speech vs. UI metadata.
+
+## Configuration
+
+STT‑Settings:
+- `vad_enabled` (bool, default true)
+- `vad_threshold` (float, default 0.5)
+- `turn_stop_secs` (float, default 0.2)
+- `min_silence_ms` (int, default 250)
+
+TTS‑Settings:
+- `tts_pcm_enabled` (bool, default true)
+- `phoneme_map_path` (str, optional JSON/YAML)
+- `target_sample_rate` (int, default 24000)
+
+Metrics:
+- `enable_voice_latency_metrics` (bool, default true)
+
+Feature Flags:
+- `tts_pcm_enabled` (bool, default true)
+- `enable_ws_tts` (bool, default false)
+Dependencies:
+- Required: `ffmpeg`, `av`
+- Optional: `espeak-ng` (phonemizer), `pyannote`
+
+ Security & Privacy:
+- Do not log raw audio payloads; scrub PII from logs/metrics
+- Configurable retention for any persisted audio (opt‑in diarization workflows)
+- Avoid secrets in metric labels; bound label cardinality
+
+## Measurement Model
+
+Timestamps (server‑side):
+- `EOS_detected_at`: VAD detects end‑of‑speech in WS STT loop
+- `STT_final_emitted_at`: final transcript frame emitted on WS
+- `TTS_request_started_at`: TTS handler receives request (REST) or prompt (WS‑TTS)
+- `TTS_first_chunk_sent_at`: first audio bytes written to socket/response
+
+Derived metrics:
+- `stt_final_latency_seconds = STT_final_emitted_at - EOS_detected_at`
+- `tts_ttfb_seconds = TTS_first_chunk_sent_at - TTS_request_started_at`
+- `voice_to_voice_seconds = TTS_first_chunk_sent_at - EOS_detected_at`
+
+Correlation:
+- Propagate `X-Request-Id` (or generate UUIDv4) across WS/REST; include in logs/spans.
+
+## Telemetry & Metrics
+
+Histograms
+- `voice_to_voice_seconds{provider,route}`: end‑of‑speech → first audio byte sent.
+- `stt_final_latency_seconds{model,variant}`: end‑of‑speech → final transcript emit.
+- `tts_ttfb_seconds{provider,voice,format}`: TTS request → first audio chunk emitted.
+  - Buckets for all histograms: `[0.01, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5]`
+
+Counters
+- `audio_stream_underruns_total{provider}`
+- `audio_stream_errors_total{component,provider}`
+
+Correlation
+- Include `request_id` and `conversation_id` on event timelines where available.
+
+Gauges
+- Reuse `tts_active_requests{provider}` from TTS service v2
+
+Endpoints
+- Prometheus: `/metrics`; JSON: `/api/v1/metrics` (when `metrics` feature enabled)
+
+## Testing Strategy
+
+Unit
+- JSON streaming parser: chunked inputs, escapes, array completion.
+- Phoneme mapper: word‑boundary correctness, idempotence.
+
+Integration
+- STT WS: VAD commit timing; latency assertions (mock clocks).
+- TTS streaming: PCM first‑chunk timing and multi‑format correctness.
+
+Performance
+- Synthetic end‑to‑end voice‑to‑voice harness; compute p50/p90, store summaries.
+- Optional diarization on recorded sessions (pyannote) for verification (local opt‑in).
+ - Negative‑path: slow reader/underrun, disconnects mid‑stream, silent/high‑noise input, malformed WS frames.
+
+## Rollout Plan
+
+Phase 1 (default on via flags)
+- Ship VAD turn detection, latency metrics, PCM format, phoneme map hooks.
+
+Phase 2 (opt‑in)
+- Structured JSON streaming; WS TTS behind feature flags.
+
+Phase 3 (optional)
+- WebRTC egress (aiortc) behind feature flag and environment readiness guide.
+
+Documentation
+- Update API docs, WebUI help, and latency tuning guidelines.
+
+## Risks & Mitigations
+
+- VAD misfires cause premature finals → conservative defaults; tunables; quick rollback.
+- PCM clients mishandle raw streams → clear examples; fall back to MP3/Opus.
+- Over‑instrumentation overhead → light timers; sampling; config‑gated metrics.
+
+## Open Questions
+
+- Default to structured JSON streaming for voice chat, or keep opt‑in per request/model?
+- Preferred UI channel for code/links (reuse existing WS vs. SSE)?
+- Region/affinity hints for distributed/self‑host deployments?
+
+## Out of Scope
+
+- New LLM providers and unrelated RAG changes.
+- Browser TURN/STUN provisioning; full WebRTC infra (unless Phase 3 explicitly enabled).
+
+## Acceptance Criteria
+
+- [ ] p50 voice‑to‑voice ≤ 1.0s on a local reference setup; p90 ≤ 1.8s.
+- [ ] p50 STT final latency ≤ 600ms; p50 TTS TTFB ≤ 250ms (reference setup).
+- [ ] PCM streaming option documented and validated with example clients.
+- [ ] Optional phoneme map configurable and applied in Kokoro path.
+- [ ] Structured streaming mode available and tested end‑to‑end.
+- [ ] Metrics exported and visible in existing registry with labels.
+ - [ ] No regressions in quotas/auth for audio endpoints; REST streaming remains backwards‑compatible.

+## Stage 1: STT Turn Detection (VAD & Commit)
+**Goal**: Add Silero VAD–driven turn detection to unified streaming STT and finalize transcripts at end‑of‑speech for lower final latency.
+**Success Criteria**: Final transcript latency p50 ≤ 600ms on reference setup; server defaults applied; client tunables accepted; no regression in quotas/auth.
+**Tests**:
+- Unit: VAD threshold/stop‑secs/mute edge cases; buffering → commit behavior; JSON message handling in WS path.
+- Integration: WS stream with synthetic audio pauses triggers timely “final” messages; latency assertions with mocked clock.
+**Reference Setup**:
+- Hardware/OS: 8‑core CPU, optional NVIDIA GPU (if Parakeet GPU path enabled); macOS 14 or Ubuntu 22.04.
+- Runtime: Python 3.11, ffmpeg ≥ 6.0, av ≥ 11.0.0.
+- Network: Localhost loopback; no WAN hops.
+- Input fixture: 10 s 16 kHz float32 speech with 250 ms trailing silence; single speaker.
+**Implementation Notes**:
+- VAD engine: Silero VAD.
+- Integration point: Unified WS loop (tldw_Server_API/app/core/Ingestion_Media_Processing/Audio/Audio_Streaming_Unified.py:1200) before forwarding to `transcriber.process_audio_chunk`.
+- Tunables and bounds (server‑validated):
+  - `vad_threshold` [0.1..0.9], default 0.5
+  - `min_silence_ms` [150..1500], default 250
+  - `turn_stop_secs` [0.1..0.75], default 0.2 (guard minimum utterance length 0.4 s)
+- Commit mapping: VAD end‑of‑speech triggers a server‑side finalize that emits `{type:"full_transcript"}` equivalent to receiving a client `commit` (see Audio_Streaming_Unified.py:1585).
+**Status**: Not Started
+
+## Stage 2: Latency Metrics (STT/TTS + Voice‑to‑Voice)
+**Goal**: Instrument STT end‑of‑speech → final transcript, TTS request → first audio chunk (TTFB), and voice‑to‑voice (EOS → first audio on wire).
+**Success Criteria**: New histograms (`stt_final_latency_seconds`, `tts_ttfb_seconds`, `voice_to_voice_seconds`) exported with labels; sampling overhead negligible; visible in metrics registry.
+**Tests**:
+- Unit: Timer guards, labels, and error‑safe recording; metrics manager registration idempotence.
+- Integration: Synthetic pipeline run records non‑zero latencies; counters for stream errors/underruns increment on fault injection.
+**Reference Setup**:
+- Same as Stage 1.
+**Implementation Notes**:
+- Metrics registration: add histograms to MetricsRegistry with buckets `[0.01, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5]`.
+- Label schema:
+  - `stt_final_latency_seconds{model,variant,endpoint="audio_unified_ws"}`
+  - `tts_ttfb_seconds{provider,voice,format,endpoint="audio.speech"}`
+  - `voice_to_voice_seconds{provider,route}`
+- Correlation: propagate `X-Request-Id` if present or generate UUIDv4 on entry to WS/REST; include in logs and internal spans to correlate metrics.
+**Status**: Not Started
+
+## Stage 3: TTS PCM Streaming Path
+**Goal**: Support `response_format=pcm` end‑to‑end for lowest overhead; document and validate output shape/sample rate.
+**Success Criteria**: `/api/v1/audio/speech` streams PCM16 with steady throughput; clients can play without encoder; existing formats unaffected.
+**Tests**:
+- Unit: PCM branch bypasses container remux; chunk framing stable; samplerate/channels honored.
+- Integration: Client consumes PCM stream with no underruns; backpressure respected.
+**Reference Setup**:
+- Same as Stage 1.
+**Implementation Notes**:
+- Content‑Type: `audio/L16; rate=; channels=`; default `rate=24000`, `channels=1`.
+- Headers: include `X-Audio-Sample-Rate: ` for clarity.
+- Negotiation: Default to provider/sample pipeline rate; optional `target_sample_rate` accepted when supported by adapter.
+**Status**: Not Started
+
+## Stage 4: Phoneme/Lexicon Overrides (Kokoro)
+**Goal**: Add configurable phoneme mapping for consistent pronunciation of brand/technical terms.
+**Success Criteria**: Config file loaded; mapping applied safely (word boundaries, case handling); feature can be toggled per‑request/provider.
+**Tests**:
+- Unit: Regex/word‑boundary correctness; idempotence on repeated runs; fallback when map missing.
+- Integration: Sample prompts produce expected pronunciations without affecting latency materially.
+**Reference Setup**:
+- Same as Stage 1.
+**Implementation Notes**:
+- Schema: YAML or JSON file with entries: `{ term: "OpenAI", phonemes: "oʊ p ən aɪ", lang?: "en", boundary?: true }`.
+- Tokenization: apply on word boundaries by default (`boundary: true`), case‑insensitive match with preserve‑case replacement.
+- Precedence: per‑request > provider‑level > global; if no match, fall back to provider defaults.
+**Status**: Not Started
+
+## Stage 5: Docs & Perf Harness
+**Goal**: Update docs and add a simple harness to measure voice‑to‑voice latency on a reference setup.
+**Success Criteria**: Docs updated (API, config, tuning); harness outputs p50/p90 and basic plots; optional diarization workflow documented.
+**Tests**:
+- Doc lint/check links; harness dry‑run with synthetic audio; CI smoke job (optional) executes harness in short mode.
+**Reference Setup**:
+- Same as Stage 1.
+**Implementation Notes**:
+- Harness location: `Helper_Scripts/voice_latency_harness/` (or `tldw_Server_API/tests/perf/`).
+- Outputs: JSON summary (p50/p90 for STT final, TTS TTFB, voice‑to‑voice); optional Prometheus text for CI scrape.
+- Fixtures: include the 10 s 16 kHz float32 speech sample and scripts to generate variants (noise/silence).
+**Status**: Not Started
+
+## Stage 6: WebSocket TTS (Optional)
+**Goal**: `/api/v1/audio/stream/tts` PCM16 streaming with backpressure and auth/rate‑limit parity with STT WS.
+**Success Criteria**: p50 TTFB ≤ 200 ms on reference; zero underruns on happy path; output parity with REST TTS.
+**Tests**:
+- Slow reader simulation; disconnects mid‑stream; bounded queue/backpressure behavior; quota enforcement and auth parity.
+**Reference Setup**:
+- Same as Stage 1.
+**Implementation Notes**:
+- Auth & quotas: mirror STT WS (API key/JWT, endpoint allowlist, quotas with standardized close codes).
+- Frames: client `{type:"prompt", text, voice?, speed?, format?:"pcm"}`; server: binary PCM16 frames (20–40 ms) + `{type:"error", message}`.
+- Backpressure: bounded queue; if consumer is slow, throttle generation or drop oldest with metric `audio_stream_underruns_total`.
+**Status**: Not Started

+# Voice Latency Harness (Stub)
+
+Purpose: quick, reproducible measurements for STT final latency, TTS TTFB, and end‑to‑end voice‑to‑voice on a local reference setup.
+
+Status: minimal stub with TTS TTFB measurement via REST streaming. Extend to WS STT and voice‑to‑voice as VAD lands.
+
+Requirements:
+- Python 3.11+
+- Optional: `pip install httpx websockets sounddevice`
+
+Usage examples:
+- TTS TTFB p50/p90 over 5 runs:
+  `python harness.py --mode tts --base http://127.0.0.1:8000 --token YOUR_TOKEN --text "Hello world" --runs 5`
+
+Outputs:
+- JSON summary to stdout: includes per‑run timings and p50/p90 for TTFB.
+
+Notes:
+- The WS TTS example client is provided under `examples/ws_tts_client.py` (server endpoint optional).
+- The PCM client example is provided under `examples/pcm_stream_client.py`.

+### Provider JSON Modes and Fallback Order
+1) Native JSON/tool/function-calling modes (OpenAI response_format, tool_calls; Anthropic tool_use; Google function calling).
+2) If unavailable, force content-type: JSON via system prompt + strict schema examples.
+3) If malformed: attempt `json_repair` once, then re-prompt with stricter constraints.
+4) After N=2 failures: return baseline ranking with warning; log structured error.
+
 ## Calibration Model
 - Model: θ per item with PL-style likelihood and MSE alignment to given human-like scores; temperature `tau` and weight `lambda_mse`.
 - Training: short-run per query (small M), optimized with AdamW; output normalized θ in [0,1].
 - Thresholding: optional bimodal GMM to pick a sampling threshold when selecting leaves.
 
+### Operational Details
+- Scope: θ is per-query, computed on the slate for that query; no cross-query reuse.
+- Minimal slate: require M ≥ 5 items with ≥ 1 positive signal; otherwise skip calibration (no-op) and surface baseline scores.
+- Early exit: stop after 50 steps or when Δloss < 1e-4 over 5 steps.
+- Fallbacks: if optimizer diverges/NaNs, revert to normalized input scores.
+- Alternatives: allow dependency-light calibration (`isotonic` or Platt-style logistic) via config flag if Torch is unavailable.

 - Concurrency: `max_concurrent_calls` default 20; configurable per environment.
 - Timeouts: default 60-120s per request; categorized backoff caps (e.g., 300s for 429s).
 - Memory: JSON streaming where possible; avoid holding large results when not needed.
+ - Token/RPS budgets: enforce `max_tokens_per_minute` and `requests_per_minute` per provider key; queue with backpressure.
 
 ## Security & Privacy
 - Secrets via env or secret store; never log API keys or request bodies with PII.
 - Redact tokens and credentials in logs; enforce structured logging without secrets.
 
+### Prompt Injection Hardening
+- Sanitize candidate text (strip/control invisible characters; normalize Unicode; optionally escape HTML/Markdown when rendering).
+- System prompts explicitly forbid following instructions in candidate text; require strictly structured JSON with no prose unless in `reasoning`.
+- Use tool/function-calling where available to reduce injection risk; validate schema strictly before use.
+- Do not log raw candidate text or full prompts; log hashed candidate IDs and aggregate statistics only.

+PRD: Modularization of /media Endpoints
+
+  - Title: Modularize and Refactor /media Endpoints
+  - Owner: Server API Team
+  - Status: Draft (v1)
+  - Target Version: v0.2.x
+
+  Background
+
+  - Current media endpoints live in a monolithic module with broad responsibilities: request parsing, auth/RBAC, rate limits, caching, input sourcing, processing orchestration, persistence, and response shaping.
+  - Key file: tldw_Server_API/app/api/v1/endpoints/media.py
+  - Existing processing libraries live under tldw_Server_API/app/core/Ingestion_Media_Processing/ and DB logic under tldw_Server_API/app/core/DB_Management/.
+  - Tests exist for uploads, security, media processing, and web scraping.
+
+  Problem Statement
+
+  - The monolith is hard to maintain and test due to tight coupling, duplicated patterns, and mixed concerns.
+  - Changes risk regressions across unrelated features.
+  - Onboarding and iteration speed are slowed by the file’s size and complexity.
+
+  Goals
+
+  - Thin, declarative routers with clear separation of concerns.
+  - Service-oriented orchestration for ingestion, processing, and persistence.
+  - Shared utilities for caching, error mapping, request normalization, and input sourcing.
+  - Preserve existing API behavior, response shapes, and performance.
+  - Improve testability and maintainability.
+
+  Non‑Goals
+
+  - No route path changes or breaking response shape changes.
+  - No DB schema changes.
+  - No rewrites of core ingestion libraries.
+  - No feature expansion beyond modularization.
+
+  Stakeholders
+
+  - Backend engineers maintaining ingestion, RAG, and audio/video flows.
+  - QA/Testing owners for Media and Web Scraping.
+  - Frontend clients relying on current /media endpoints.
+
+  Scope
+
+  - In-scope: All handlers under /api/v1/media including management (list/detail/versions), processing (no-DB paths), and ingest with persistence.
+  - Out-of-scope: Non-media endpoints; chat, audio streaming WS, MCP.
+
+  Functional Requirements
+
+  - Endpoints unchanged:
+      - List media, item details, versions (list/create/rollback).
+      - Processing endpoints (no DB): code, videos, documents, PDFs, ebooks, emails.
+      - Ingest + persist endpoint: POST /api/v1/media/add.
+      - Web scraping ingest: POST /api/v1/media/process-web-scraping.
+      - Debug schema endpoint.
+  - Shared utilities:
+      - Caching with ETag/If-None-Match for GET list/detail.
+      - Error mapping for DB and processing exceptions.
+      - Request normalization: robust form coercions, URL lists, booleans/ints.
+      - Input sourcing: URL downloads, tempdirs, upload validation.
+  - Services:
+      - Orchestrator for process-only flows (no DB).
+      - Persistence service (DB writes, versions, keywords, claims).
+  - Keep:
+      - AuthNZ and RBAC decorators.
+      - Rate limiting and backpressure hooks.
+      - Quota checks and metrics emission.
+      - Claims extraction and analysis when enabled.
+
+  Non‑Functional Requirements
+
+  - Performance: No regression; caching enabled for list/detail.
+  - Reliability: Transactions around persistence; clear cleanup semantics for temp dirs.
+  - Security: Preserve validation, RBAC, rate limits, and input file checks; no logging of secrets.
+  - Observability: Loguru usage consistent with main.py; metrics labels maintained.
+  - Testing: All existing tests pass; new unit tests for utilities (>80% coverage in new code).
+  - Compatibility: Keep tldw_Server_API/app/api/v1/endpoints/media.py as a compatibility shim exporting router.
+
+  Success Metrics
+
+  - Monolith shrinks to shim; new package assumes routes.
+  - Cyclomatic complexity and size reduced per endpoint module.
+  - Test pass rate unchanged or improved; new unit tests for utilities.
+  - Endpoint latencies/throughput unchanged within measurement noise.
+  - Developer feedback shows faster iteration and onboarding.
+
+  Technical Design
+
+  - Endpoints Package (new)
+      - tldw_Server_API/app/api/v1/endpoints/media/__init__.py (exposes router, includes subrouters)
+      - tldw_Server_API/app/api/v1/endpoints/media/listing.py (GET list/search if exists)
+      - tldw_Server_API/app/api/v1/endpoints/media/item.py (GET, PATCH/PUT, DELETE)
+      - tldw_Server_API/app/api/v1/endpoints/media/versions.py (GET versions, POST version, PUT rollback)
+      - tldw_Server_API/app/api/v1/endpoints/media/add.py (POST /add)
+      - tldw_Server_API/app/api/v1/endpoints/media/process_code.py
+      - tldw_Server_API/app/api/v1/endpoints/media/process_videos.py
+      - tldw_Server_API/app/api/v1/endpoints/media/process_documents.py
+      - tldw_Server_API/app/api/v1/endpoints/media/process_pdfs.py
+      - tldw_Server_API/app/api/v1/endpoints/media/process_ebooks.py
+      - tldw_Server_API/app/api/v1/endpoints/media/process_emails.py
+      - tldw_Server_API/app/api/v1/endpoints/media/web_scrape.py
+      - tldw_Server_API/app/api/v1/endpoints/media/debug.py
+  - API Utilities (new)
+      - tldw_Server_API/app/api/v1/utils/cache.py (ETag generation, If-None-Match, TTL)
+      - tldw_Server_API/app/api/v1/utils/http_errors.py (map DatabaseError/InputError/ConflictError to FastAPI HTTPException)
+      - tldw_Server_API/app/api/v1/utils/request_parsing.py (form coercions, URL list normalization, safe bool/int parsing)
+  - Core Orchestration (new)
+      - tldw_Server_API/app/core/Ingestion_Media_Processing/pipeline.py
+          - Input resolution (URL or upload) → type-specific processor → standard result list
+      - tldw_Server_API/app/core/Ingestion_Media_Processing/input_sourcing.py
+          - Wraps _download_url_async, Upload_Sink.process_and_validate_file, tempdir lifecycle
+      - tldw_Server_API/app/core/Ingestion_Media_Processing/result_normalization.py
+          - Uniform MediaItemProcessResponse shape: status, metadata, content, chunks, analysis, claims, warnings
+      - tldw_Server_API/app/core/Ingestion_Media_Processing/persistence.py
+          - DB transactions, version creation, keywords, claims storage
+  - Compatibility Shim
+      - tldw_Server_API/app/api/v1/endpoints/media.py re-exports router from the new package.
+  - Caching Design
+      - Generate ETag based on response content hash (excluding volatile fields).
+      - Honor If-None-Match; return 304 when matched.
+      - Configurable TTL via config['CACHE_TTL']; disable when Redis disabled.
+  - Error Mapping
+      - DatabaseError → 500 (unless refined by context, e.g., not found → 404).
+      - InputError → 400/422 based on validation context.
+      - ConflictError → 409 for resource conflicts.
+      - Graceful fallbacks to 500 with safe messages (no secrets).
+  - Security & AuthNZ
+      - Preserve Depends(get_request_user), PermissionChecker(MEDIA_CREATE), and rbac_rate_limit("media.create") on routes that modify data.
+      - Keep file extension allowlists per media type and size caps.
+      - Maintain URL safety checks and content-type based filtering.
+
+  API Compatibility
+
+  - No changes to route paths, query params, or body schemas.
+  - Response models remain per tldw_Server_API/app/api/v1/schemas/media_response_models.py:1.
+  - Request models remain per tldw_Server_API/app/api/v1/schemas/media_request_models.py:1 (allow internal re-exports only).
+
+  Data Model Impact
+
+  - None. All DB operations continue via MediaDatabase and existing DB helpers.
+
+  Telemetry & Metrics
+
+  - Maintain existing counters for uploads, bytes, and per-route usage events.
+  - Keep TEST_MODE diagnostics behavior, but confine to helpers to reduce handler clutter.
+
+  Rollout & Backout
+
+  - Rollout: Incremental PRs per stage; keep shim in place; run full pytest suite after each stage.
+  - Backout: Revert to previous media.py monolith; keep migrations isolated to code structuring (no DB migration).
+
+  Risks & Mitigations
+
+  - Tests patch internals of media.py: keep temporary re-exports of commonly patched functions in the shim.
+  - Route order conflicts: keep /{media_id:int} with type converter and preserve registration order.
+  - Behavior drift in form coercion: centralize and add unit tests in utils/request_parsing.py.
+  - Unexpected perf cost from caching: keep cache optional; measure and tune TTL and ETag generation.
+
+  Acceptance Criteria
+
+  - All existing tests pass:
+      - tldw_Server_API/tests/Media/*
+      - tldw_Server_API/tests/http_client/test_media_download_helper.py
+      - tldw_Server_API/tests/Web_Scraping/test_friendly_ingest_crawl_flags.py
+  - New unit tests for cache, request parsing, input sourcing, and normalization at >80% coverage.
+  - API responses identical for representative golden cases across endpoints.
+  - Logs and metrics preserved; no sensitive leakage.
+
+  Open Questions
+
+  - Do any external integrations or clients patch/import internal helpers from media.py? If yes, list to re-export for one release cycle.
+  - Should we add a feature flag to force old router? Default plan relies on shim; a flag is optional.
+
+  Timeline (Rough)
+
+  - Design and approval: 1–2 days
+  - Utilities + skeleton package: 1 day
+  - List/Item/Versions extraction: 1–2 days
+  - Process-only endpoints: 3–4 days
+  - /add persistence extraction: 2–3 days
+  - Web scraping extraction: 1 day
+  - Cleanup + docs + final tests: 1–2 days
+  - Total: ~10–15 working days
+
+  Dependencies
+
+  - Redis (optional cache).
+  - Existing core modules: Upload sink, PDF/Doc/AV processors, DB management, usage/metrics.
+  - AuthNZ dependencies and rate limiters.
+
+  Implementation Plan
+
+  - Stage 0: PRD Sign‑Off
+      - Deliverable: Approved PRD.
+      - Exit: Stakeholder sign-off.
+  - Stage 1: Skeleton & Utilities
+      - Create endpoints/media/ package with __init__.py exporting router.
+      - Add api/v1/utils/cache.py, utils/http_errors.py, utils/request_parsing.py.
+      - Keep endpoints/media.py as shim importing router from package.
+      - Tests: unit tests for cache and parsing utilities.
+  - Stage 2: Read‑Only Endpoints
+      - Move GET list and GET item to listing.py and item.py.
+      - Move versions GET/POST/PUT to versions.py.
+      - Apply cache decorator for list/detail.
+      - Tests: run Media list/detail/version tests; verify ETag behavior on list/detail.
+  - Stage 3: Process‑Only Endpoints
+      - Create core orchestrator: pipeline.py, input_sourcing.py, result_normalization.py.
+      - Move process_code, process_documents, process_pdfs, process_ebooks, process_emails, process_videos into dedicated files; handlers delegate to orchestrator.
+      - Tests: adapt existing tests; add unit tests for input sourcing and normalization.
+  - Stage 4: Persistence Path (/add)
+      - Create persistence.py with transactional DB writes, keyword tagging, claims storage.
+      - Extract /add endpoint to add.py; reuse orchestrator for processing and call persistence layer.
+      - Preserve quotas, metrics, and claims feature flags.
+      - Tests: /add end-to-end tests; quota and error mapping coverage.
+  - Stage 5: Web Scraping
+      - Move handler to web_scrape.py; ensure it delegates to services/web_scraping_service.
+      - Tests: web scraping tests (crawl flags, summarization toggles).
+  - Stage 6: Debug Endpoint
+      - Move schema introspection to debug.py.
+      - Tests: basic health assertions.
+  - Stage 7: Cleanup & Docs
+      - Ensure media.py shim only re-exports router.
+      - Update docs:
+          - Docs/Code_Documentation/Ingestion_Media_Processing.md
+          - Docs/Code_Documentation/Ingestion_Pipeline_*
+          - Add Docs/Design/Media_Endpoint_Refactor.md overview.
+      - Tests: full suite with coverage.
+  - Definition of Done (per stage)
+      - Tests passing (unit + integration for impacted endpoints).
+      - Response shapes verified with golden samples.
+      - Lint/format per project conventions.
+      - Logs clean; no sensitive data exposure.
+      - Update CHANGELOG (internal note only; no external API changes).
+  - Validation Steps
+      - Run: python -m pytest -v
+      - Coverage: python -m pytest --cov=tldw_Server_API --cov-report=term-missing
+      - Manual: spot-check /api/v1/media list/detail, /add, /process-* endpoints.
+  - Backout Plan
+      - Revert to last commit where media.py monolith was active.
+      - Keep compatibility shim until next minor release.

+# tldw_server New User Guide
+
+This guide walks a brand-new user through the shortest path to a working local deployment, a first media ingestion, and the most useful follow-up resources. It complements `README.md` by focusing on actionable steps rather than full feature listings.
+
+---
+
+## 1. What You Get
+- **API-first media assistant**: ingest video/audio/docs, run hybrid RAG, and expose OpenAI-compatible Chat, Audio, and Embeddings endpoints.
+- **Bring your own models**: plug in 16+ commercial or local providers (OpenAI, Anthropic, vLLM, Ollama, etc.).
+- **Knowledge tooling**: searchable notes, prompt studio, character chats, evaluations, Chatbooks import/export.
+- **Deployment flexibility**: run everything locally with Python, Docker Compose, or pair the backend with the Next.js Web UI.
+
+---
+
+## 2. Before You Start
+
+| Requirement | Notes |
+|-------------|-------|
+| **OS** | Linux, macOS, WSL2, or Windows with Python build tools |
+| **Python** | 3.11+ (3.12/3.13 tested) |
+| **System packages** | `ffmpeg`, `portaudio/pyaudio` (macOS) or `python3-pyaudio` (Linux) for audio capture |
+| **Disk** | Plan for SQLite DBs under `Databases/` plus media storage |
+| **GPU (optional)** | Enables faster STT/LLM backends; fallback CPU works |
+| **Provider credentials** | Add OpenAI/Anthropic/etc. keys to `.env` or `Config_Files/config.txt` |
+
+> Tip: If you are on Windows without WSL2, install the Python build tools and `ffmpeg` manually, or use the Docker path below to avoid native dependencies.
+
+### 2.1 Install ffmpeg + audio capture libraries
+
+These packages let the server transcode media and access microphones. Install **before** running `pip install -e .`.
+
+| Platform | Commands |
+|----------|----------|
+| **macOS (Homebrew)** | `brew install ffmpeg portaudio`
    `pip install pyaudio` |
+| **Ubuntu/Debian** | `sudo apt update && sudo apt install ffmpeg portaudio19-dev python3-pyaudio` |
+| **Fedora** | `sudo dnf install ffmpeg portaudio portaudio-devel python3-pyaudio` |
+| **Windows** | `choco install ffmpeg` (or download binaries)
    `pip install pipwin && pipwin install pyaudio` |
+| **WSL2** | Use the Linux instructions inside WSL; Windows audio devices stay accessible through ALSA/Pulse. |
+
+> If `pip install pyaudio` fails, install the system `portaudio` dev headers first (Linux) or use `pipwin` (Windows) to pull a matching wheel.
+
+---
+
+## 3. Fast Path: Local Python Install
+
+Follow these steps from the repository root (`tldw_server2/`):
+
+### 3.1 Create a virtual environment and install dependencies
+```bash
+python3 -m venv .venv
+source .venv/bin/activate          # Windows: .venv\Scripts\activate
+pip install -e .
+# Optional extras:
+# pip install -e ".[dev]"          # linting/tests
+# pip install -e ".[multiplayer]"  # Postgres + multi-user helpers
+# pip install -e ".[otel]"         # telemetry exporters
+```
+
+### 3.2 Configure auth + provider settings
+Create `.env` (or extend if it already exists):
+```bash
+cat > .env <<'EOF'
+AUTH_MODE=single_user
+SINGLE_USER_API_KEY=CHANGE_ME_TO_SECURE_API_KEY
+DATABASE_URL=sqlite:///./Databases/users.db
+# Provider keys (examples)
+# OPENAI_API_KEY=sk-...
+# ANTHROPIC_API_KEY=...
+EOF
+```
+You can also keep large provider configs in `tldw_Server_API/Config_Files/config.txt`.
+
+### 3.3 Initialize AuthNZ and databases
+```bash
+python -m tldw_Server_API.app.core.AuthNZ.initialize
+```
+This validates the environment, seeds the AuthNZ DB, and prints the API key for single-user mode if not set.
+
+### 3.4 Run the API
+```bash
+python -m uvicorn tldw_Server_API.app.main:app --reload
+```
+- Docs/UI: http://127.0.0.1:8000/docs
+- Legacy Web UI: http://127.0.0.1:8000/webui/
+
+### 3.5 Smoke-test the API
+Use your API key (`SINGLE_USER_API_KEY`) in the header:
+```bash
+curl -X POST "http://127.0.0.1:8000/api/v1/chat/completions" \
+  -H "Content-Type: application/json" \
+  -H "X-API-KEY: CHANGE_ME_TO_SECURE_API_KEY" \
+  -d '{
+        "model": "openai:gpt-4o-mini",
+        "messages": [{"role": "user", "content": "Say hello from tldw_server"}]
+      }'
+```
+Replace `model` with anything configured in your provider list (see `/api/v1/llm/providers` for active entries).
+
+---
+
+## 4. Runtime & Provider Configuration
+
+Once the server boots, you’ll likely tailor behaviour, credentials, and model lists. Two files drive most settings:
+
+### 4.1 `.env`: secrets, auth, and DB targets
+- Location: `tldw_server2/.env` (same folder as `pyproject.toml`).
+- Best place for **secrets**: API keys, DB passwords, Postgres URLs, JWT secrets.
+- Common fields:
+  - `AUTH_MODE` = `single_user` (API key header) or `multi_user` (JWT/auth endpoints).
+  - `SINGLE_USER_API_KEY` or `JWT_SECRET_KEY`.
+  - `DATABASE_URL` (AuthNZ DB), `JOBS_DB_URL`, `TEST_DATABASE_URL`.
+  - Provider keys: `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GROQ_API_KEY`, etc.
+  - `STREAMS_UNIFIED`, `LOG_LEVEL`, and other boolean toggles documented in `Env_Vars.md`.
+- After editing `.env`, restart the FastAPI server (env variables are read at startup).
+
+### 4.2 `config.txt`: user-facing defaults and feature flags
+- Location: `tldw_Server_API/Config_Files/config.txt`.
+- Back this file up or keep a copy in `.git/info/exclude` if you don’t want Git noise.
+- Controls everything from file-size limits to chat rate limits. Key sections:
+  - `[Server]`: `disable_cors`, `allow_remote_webui_access`, and `webui_ip_allowlist` for restricting the legacy UI.
+  - `[Media-Processing]`: per-file-size caps/timeouts for video/audio/PDF ingestion.
+  - `[Chat-Module]`: streaming defaults, history depth, rate limits.
+  - `[Database]`: choose SQLite vs Postgres for content (`pg_*` fields).
+  - `[Chunking]`, `[RAG]`, `[Embeddings]`: tune context windows and vector backends.
+- Use any editor, then restart the API (or run `python -m tldw_Server_API.app.core.AuthNZ.initialize` once to validate the config).
+
+### 4.3 Adding cloud LLM providers & keys
+1. Drop the API key into `.env`, e.g. `ANTHROPIC_API_KEY=sk-ant-...`.
+2. In `config.txt`, open the `[API]` section and set the defaults for that provider:
+   ```ini
+   [API]
+   anthropic_model = claude-3-5-sonnet-latest
+   anthropic_temperature = 0.6
+   default_api = anthropic        # optional: make it the default `/chat/completions` target
+   ```
+3. If the provider exposes a custom base URL, set it here as well (e.g. `qwen_api_base_url`).
+4. Call `GET /api/v1/llm/providers` to confirm the provider is now listed.
+
+### 4.4 Pointing to self-hosted/local LLMs
+Edit the `[Local-API]` section of `config.txt`. Each entry maps to a backend host:
+
+```ini
+[Local-API]
+ollama_api_IP = http://192.168.1.50:11434/v1/chat/completions
+ollama_model = llama3:instruct
+vllm_api_IP = http://localhost:8001/v1/chat/completions
+vllm_model = my-hf-model-id
+tabby_api_IP = http://127.0.0.1:5000/v1/chat/completions
+```
+
+- Use full URLs (protocol + host + port + path). For LAN hosts, whitelist their CIDRs via `[Server] webui_ip_allowlist`.
+- Update temperature/top_p/max_tokens per provider if the backend expects different defaults.
+- After editing, restart the API so the provider manager reloads the endpoints.
+
+### 4.5 Where to adjust user-facing behaviour
+- **Rate limits**: `[Chat-Module] rate_limit_per_minute`, `[Character-Chat]` guards.
+- **Storage paths**: `[Database] sqlite_path`, `backup_path`, and `chroma_db_path`.
+- **Web access**: `[Server] allow_remote_webui_access=true` plus `webui_ip_allowlist=10.0.0.0/24`.
+- **Setup UI**: `[Setup] allow_remote_setup_access=true` if you must run first-time setup remotely (only on trusted networks).
+
+---
+
+## 5. Docker Compose Path (All Services)
+
+If you prefer containers (or are on Windows without build tools):
+```bash
+# Base stack (SQLite users DB + Redis + app)
+docker compose -f Dockerfiles/docker-compose.yml up -d --build
+
+# Multi-user/Postgres mode
+export AUTH_MODE=multi_user
+export DATABASE_URL=postgresql://tldw_user:TestPassword123!@postgres:5432/tldw_users
+docker compose -f Dockerfiles/docker-compose.yml \
+             -f Dockerfiles/docker-compose.override.yml up -d --build
+```
+After the containers are up, initialize AuthNZ inside the app container:
+```bash
+docker compose -f Dockerfiles/docker-compose.yml exec app \
+  python -m tldw_Server_API.app.core.AuthNZ.initialize
+```
+- Check logs: `docker compose -f Dockerfiles/docker-compose.yml logs -f app`
+- Optional overlays: `docker-compose.dev.yml` (unified streaming), `docker-compose.pg.yml` (pgvector/pgbouncer), proxy variants.
+
+---
+
+## 6. Connect the Next.js Web UI (Optional but Friendly)
+The `tldw-frontend/` directory hosts the current Next.js client.
+```bash
+cd tldw-frontend
+cp .env.local.example .env.local        # set NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
+echo "NEXT_PUBLIC_X_API_KEY=CHANGE_ME_TO_SECURE_API_KEY" >> .env.local
+npm install
+npm run dev -- -p 8080
+```
+Open http://localhost:8080 to use the UI. CORS defaults allow 8080, so matching the port avoids manual server tweaks.
+
+---
+
+## 7. Process Your First Media File
+Once the API is running:
+1. Place a sample file under `Samples/` (the repo already includes several fixtures).
+2. Use the media ingestion endpoint:
+```bash
+curl -X POST "http://127.0.0.1:8000/api/v1/media/process" \
+  -H "X-API-KEY: CHANGE_ME_TO_SECURE_API_KEY" \
+  -F "source_type=file" \
+  -F "file=@Samples/sample_audio.mp3" \
+  -F "title=Sample Audio" \
+  -F "tags=demo,quickstart"
+```
+3. Track progress via `/api/v1/media/status/{job_id}` (returned from the process call) or use `/api/v1/media/search` once ingestion finishes.
+
+---
+
+## 8. Common Next Steps
+- **Explore docs**: OpenAPI docs at `/docs`, plus deep dives in `Docs/` (RAG, AuthNZ, MCP, etc.).
+- **List available providers**: `GET /api/v1/llm/providers` to confirm names/models you can target.
+- **Run tests**: `python -m pytest -v` (add `-m "unit"` or `-m "integration"` as needed).
+- **Switch to PostgreSQL**: set `DATABASE_URL` and leverage `tldw_Server_API/app/core/DB_Management/` migration helpers.
+- **Enable unified streaming**: export `STREAMS_UNIFIED=1` or use the Docker dev overlay for SSE/WS pilots.
+
+---
+
+## 9. Troubleshooting Cheat Sheet
+
+| Symptom | Likely Cause | Fix |
+|---------|--------------|-----|
+| `uvicorn` crashes on startup | Missing `.env` or invalid provider config | Re-run `AuthNZ.initialize`, inspect `.env` values |
+| `ffmpeg`/audio errors | Binary not installed or not in `PATH` | Install `ffmpeg`, restart terminal |
+| `X-API-KEY` rejected | Key mismatch or wrong auth mode | Verify `AUTH_MODE`, check env, inspect server logs |
+| Media stuck in `processing` | Background workers blocked or DB locked | Check logs under `Databases/`, ensure only one writer, consider Postgres |
+| Docker health fails | Compose overlay mismatch | Start with base compose file, then add overlays gradually |
+
+> Enable debug logging by setting `LOG_LEVEL=DEBUG` before launching the server if you need granular traces (Loguru handles formatting).
+
+---
+
+## 10. Where to Learn More
+- `README.md`: feature matrix, architecture diagrams, release notes.
+- `Docs/`: AuthNZ, RAG, TTS/STT, MCP, deployment profiles.
+- `Project_Guidelines.md`: development philosophy if you plan to contribute.
+- GitHub Issues/Discussions: report bugs, request features, or ask setup questions.
+
+Happy building! Once you ingest your first file and run a chat completion, you have the full pipeline working—everything else (prompt studio, evaluations, MCP, browser extension) builds on the same foundation.

+# Prompt Studio - MCTS Sequence Optimization (MCTS-OPS Inspired) PRD
+
+- Version: v1.0 (MVP without sandboxed code execution)
+- Owner: Prompt Studio
+- Stakeholders: API team, WebUI team, DB team
+- Target Release: 1-2 sprints for MVP, +1 sprint for code evaluator
+
+## Overview
+
+Add a new optimization strategy ("mcts") that treats prompt design as sequential planning over multi-step prompt sequences with Monte Carlo Tree Search (MCTS). Leverage low-cost LLM scoring and reward backpropagation to explore, evaluate, and refine prompt sequences; optionally apply a feedback revision loop to low-reward candidates. Integrates with existing Prompt Studio endpoints, job queue, TestRunner, PromptExecutor, and WebSocket events.
+
+## Implementation Status (Rolling)
+
+- Status: In Progress
+- Last Updated: [auto]
+
+Completed (MVP + MCTS core):
+- API/schema: endpoint validation for `optimizer_type="mcts"` + `strategy_params` (range checks; includes `mcts_simulations`, `mcts_max_depth`, `mcts_exploration_c`, `prompt_candidates_per_node`, `score_dedup_bin`, `early_stop_no_improve`, `token_budget`, `feedback_*`, model overrides).
+- Engine: `MCTSOptimizer` integrated with `OptimizationEngine` under strategy `"mcts"`.
+- MCTS core algorithm: full tree search with Node(Q, N, parent/children, score_bin), UCT selection (`mcts_exploration_c`), expansion with `prompt_candidates_per_node` and sibling dedup using `score_dedup_bin`, simulation over multi-segment sequences (via `PromptDecomposer`), and backpropagation of rewards.
+- Contextual generation: carries accumulated system context across segments for candidate creation; user content kept stable for evaluation.
+- Optional feedback/refinement: honors `feedback_enabled`, `feedback_threshold`, `feedback_max_retries` by delegating to `IterativeRefinementOptimizer` and re-evaluating improved variants.
+- Optimization MVP: iterative candidate variant generator with evaluation via existing `TestRunner`/`PromptExecutor`; early stop on no-improve.
+- ProgramEvaluator Phase 2 (sandbox): feature-gated per project and env; extracts Python from LLM output, executes under isolated subprocess with import whitelist and no file/network, evaluates objective/constraints, and maps to reward [-1..10]; wired into `TestRunner` for `runner="python"` cases.
+- PromptQualityScorer upgraded: optional cheap LLM scoring fallback (configurable `scorer_model`) blended with heuristics; in-memory TTL cache to reduce token usage; explicit `score_to_bin` helper for consistent dedup bins.
+- Cost controls: MCTS tracks cumulative tokens for scorer/rephrase calls via `PromptExecutor` and enforces `token_budget` with early stop; `_call_llm` adds simple backoff/retry for 429/rate limits; in-memory caching for segment rephrases and evaluation results to avoid duplicate rollouts; optional DB-backed cache (sync_log) for scorer/rephrase/eval with TTL.
+- Metrics + instrumentation: Records `sims_total`, `tree_nodes`, `avg_branching`, `best_reward`, `tokens_spent`, `duration_ms` via `prompt_studio_metrics.record_mcts_summary`. Error counters added (`prune_low_quality`, `prune_dedup`, `scorer_failure`, `evaluator_timeout`).
+- WS lifecycle + cancellation: Broadcasts `OPTIMIZATION_STARTED` and `OPTIMIZATION_COMPLETED`; periodic cancellation checks exit long loops promptly.
+- WebSocket: lifecycle events (started/completed) and throttled per-simulation progress broadcasts (iteration, current score, best score) via shared `EventBroadcaster`. Throttle interval configurable via `ws_throttle_every` (defaults ~ n_sims/50).
+- Persistence (trace): Each throttled iteration is persisted via `record_optimization_iteration` with compact variant metadata (prompt_id, system_hash, preview). Final compact search trace (best path + top-K) included in `final_metrics.trace` for the optimization row.
+- Feature gating: MCTS strategy is disabled by default; enabled in development via canary or explicitly with `PROMPT_STUDIO_ENABLE_MCTS=true`. Debug decision dumps controlled by `PROMPT_STUDIO_MCTS_DEBUG_DECISIONS=true`.
+- Docs & Guides: See `Docs/Guides/Prompt_Studio_MCTS_Guide.md`, `Docs/Guides/Prompt_Studio_Program_Evaluator.md`, and `Docs/Guides/Prompt_Studio_Ablations.md`.
+- Quality/Decomposition helpers: heuristic `PromptQualityScorer` (0..10) and `PromptDecomposer` (naive segment split); pruning via `min_quality` strategy param.
+- Program Evaluator (Phase 2 groundwork): feature-flagged `ProgramEvaluator` stub (no code exec) wired into `TestRunner` for runner="python" cases; maps heuristic reward to aggregate score when enabled.
+- OpenAPI example: added an `mcts` example payload to `/optimizations/create` for discoverability.
+
+In Progress / Planned next:
+- ProgramEvaluator sandbox (actual execution) behind flag; per-project controls and resource limits.
+- Docs: examples, UI notes, and ablation scripts; README WS payload samples and advanced usage.
+ - Tests: expand unit/integration/perf coverage; throttle WS for large n_sims.
+
+## Goals
+
+- Improve robustness on "hard" tasks by exploring prompt sequences, not just single prompts.
+- Provide token-aware, budget-bounded optimization with early stops and deduplication.
+- Stream real-time progress via existing Prompt Studio WebSocket (WS).
+
+## Non-Goals
+
+- No new public endpoints (use existing `/api/v1/prompt-studio/optimizations/create`).
+- No WebUI redesign (rely on current WS channel and optimization views).
+- No mandatory sandboxed code execution in MVP (added in v2 behind a feature flag).
+
+## Personas & Use Cases
+
+- Prompt engineers: Optimize prompts for difficult tasks with structured, multi-step sequences.
+- QA/researchers: Run controlled experiments comparing strategies (iterative vs mcts) on the same test set.
+- Developers: Tune performance/cost knobs; introspect search traces and best candidate path.
+
+## Functional Requirements
+
+### Strategy: "mcts"
+
+Inputs (via `optimization_config.strategy_params`):
+
+- `mcts_simulations` (int, default 20, 1-200)
+- `mcts_max_depth` (int, default 4, 1-10)
+- `mcts_exploration_c` (float, default 1.4, 0.1-5.0)
+- `prompt_candidates_per_node` (int, default 3, 1-10)
+- `score_dedup_bin` (float, default 0.1, 0.05-0.5)
+- `feedback_enabled` (bool, default true)
+- `feedback_threshold` (float 0-10, default 6.0)
+- `feedback_max_retries` (int, default 2)
+- `token_budget` (int, default 50_000)
+- `early_stop_no_improve` (int, default 5)
+- `scorer_model` (string, default small/cheap model)
+- `rollout_model` (string, default configured model)
+- `min_quality` (float 0-10, default 0.0) - prune low-quality variants pre-evaluation using heuristic scorer (implemented in MVP).
+
+MCTS loop:
+
+- Selection: UCT selects children by `Q/N + c * sqrt(log(Np)/N)`.
+- Expansion: Generate K prompt variants for current segment, score each; bin scores by `score_dedup_bin` and reuse siblings with same bin to cap branching.
+- Simulation: Build a candidate sequence; call PromptExecutor/TestRunner to get a numeric reward (0-10). Failures score -1.
+- Backpropagation: Update Q, N along the path; track best-so-far.
+- Optional feedback: If reward < threshold, apply one self-refine iteration and re-evaluate; use `max(reward, refined_reward)`.
+
+Decomposition & context:
+
+- Decompose task/goal into segments (context, instruction, constraints, examples). Keep 3-6 segments.
+- Each next generation receives "context so far" to maintain coherence.
+
+### Job Integration
+
+- Create via existing POST `/api/v1/prompt-studio/optimizations/create` with `optimizer_type="mcts"`.
+- Run under job processor; stream progress via WS (per simulation and on best update).
+
+### Storage
+
+- Use existing optimization row + `record_optimization_iteration(...)` to persist per-simulation/iteration metrics; no schema change in v1.
+
+### Observability
+
+- Emit metrics: `sims_total`, `best_reward`, `avg_branching`, `nodes_expanded`, `token_spend`.
+- WS events include current best reward, simulation index, and optional short trace summary.
+  - Implemented: WS progress broadcasts per simulation (current and best scores; pruned events). Metrics pending.
+
+## Non-Functional Requirements
+
+- Token/cost control:
+  - Token budget hard-cap; early stop on `early_stop_no_improve`.
+  - Use cheap model for PromptQualityScorer; reserve better model for final rollouts.
+- Performance:
+  - Default simulations (20) complete within typical job SLAs; concurrency capped; backpressure via queue.
+- Reliability:
+  - Fail closed; if scorer/LLM unavailable, job aborts gracefully with error message.
+- Compatibility:
+  - Backwards compatible with existing API and storage.
+
+Implemented so far:
+- Input validation and safe defaults; optional WS path used only when WS endpoints are loaded (no hard dependency).
+
+## Security & Privacy
+
+- MVP: No arbitrary code execution.
+- v2 (optional): ProgramEvaluator behind feature flag
+  - Sandboxed execution (timeout, memory, no network/files); whitelist imports; capture stdout/stderr; scrub logs.
+  - Never log user secrets; redact inputs in traces.
+- MVP: non-executing `ProgramEvaluator` stub wired under flag - no code runs; returns heuristic reward only when enabled.
+- Rate limiting:
+  - Reuse existing Prompt Studio limits in endpoint deps.
+
+## User Experience
+
+- API flow:
+  - Client submits optimization with `optimizer_type="mcts"` and strategy params.
+  - Poll via GET optimization status or subscribe to WS for progress.
+  - On completion, response includes `optimized_prompt_id`, metrics, and summary.
+- WebSocket:
+  - Broadcast simulation updates: `{optimization_id, sim_index, depth, reward, best_reward, token_spend_so_far}`.
+  - Final “completed” event with summary.
+
+## Architecture
+
+New components (under `tldw_Server_API/app/core/Prompt_Management/prompt_studio/`):
+
+- `MctsOptimizer`: Orchestrates tree search and reward loop; plugs into `OptimizationEngine`.
+- `PromptDecomposer`: Simple LLM/heuristic splitter into 3-6 segments.
+- `PromptQualityScorer`: Cheap LLM/heuristic scorer, returns 0-10 and a `score_bin`.
+- `MctsTree` / `UctPolicy`: Node structs with Q, N, score_bin, prompt fragment; selection/expansion/backprop.
+- `ContextualGenerator`: Uses `PromptExecutor._call_llm` directly to include “context so far”.
+- `ProgramEvaluator` (v2): Optional sandboxed code runner.
+
+Implemented so far:
+- `MctsOptimizer` (MVP iterative best-of-N search, early stop, WS broadcasts)
+- `PromptQualityScorer` (heuristic)
+- `PromptDecomposer` (heuristic)
+- `ProgramEvaluator` (non-executing stub, feature-flagged) + `TestRunner` wiring
+
+Integration points:
+
+- `optimization_engine.py`: add routing for `optimizer_type == "mcts"`.
+- `optimization_strategies.py`: house helper classes if shared across strategies.
+- `api/v1/schemas/prompt_studio_optimization.py`: schema validation for mcts params.
+- `api/v1/endpoints/prompt_studio_optimization.py` (create): validation guard rails.
+- `job_processor.py`: status broadcasts compatible with WS `EventBroadcaster`.
+
+## API & Schemas
+
+Request example (POST `/api/v1/prompt-studio/optimizations/create`):
+
+```json
+{
+  "project_id": 1,
+  "initial_prompt_id": 12,
+  "test_case_ids": [1, 2, 3],
+  "optimization_config": {
+    "optimizer_type": "mcts",
+    "max_iterations": 20,
+    "target_metric": "accuracy",
+    "strategy_params": {
+      "mcts_simulations": 20,
+      "mcts_max_depth": 4,
+      "mcts_exploration_c": 1.4,
+      "prompt_candidates_per_node": 3,
+      "score_dedup_bin": 0.1,
+      "feedback_enabled": true,
+      "feedback_threshold": 6.0,
+      "feedback_max_retries": 2,
+      "token_budget": 50000,
+      "early_stop_no_improve": 5
+    }
+  }
+}
+```
+
+Validation:
+
+- Enforce numeric ranges; ensure non-negative budgets; cap candidates per node.
+ - Implemented in `/optimizations/create` strategy validation.
+
+## Scoring & Evaluation
+
+- MVP reward:
+  - Use `TestRunner.run_single_test` aggregate score (0-1) directly for optimization decisions and final payloads.
+  - Internal thresholds may use scaled values, but API responses and metrics remain 0-1. Failures (exceptions) contribute 0 unless otherwise specified.
+- v2 reward (optional):
+  - For test cases marked “program” (runner="python"), run `ProgramEvaluator` with its internal reward mapping; normalize to 0-1 when aggregating for optimization results.
+
+## Metrics & Logging
+
+- Metrics (expose via `monitoring.py`):
+  - `prompt_studio.mcts.sims_total`, `prompt_studio.mcts.best_reward`, `prompt_studio.mcts.tree_nodes`, `prompt_studio.mcts.avg_branching`, `prompt_studio.mcts.tokens_spent`, `prompt_studio.mcts.duration_ms`.
+  - Error counters: `prompt_studio.mcts.errors_total{error=prune_low_quality|prune_dedup|scorer_failure|evaluator_timeout}`.
+- Logs:
+  - Per simulation decision, reward, and improvement, throttled to avoid PII leakage.
+ - Implemented: metrics collection, lifecycle + throttled WS broadcasts, per-iteration DB traces.
+
+## Rollout Plan
+
+- Phase 1 (MVP):
+  - Implement `MctsOptimizer` with scorer and contextual generator; no code execution.
+  - Endpoint validation, WS progress events, metrics, docs.
+- Current status: `MctsOptimizer` MVP, heuristic scorer/decomposer, WS progress, validation and docs completed.
+- Phase 2 (Optional):
+  - Add `ProgramEvaluator` with secure sandbox; feature flag + config; basic code tasks.
+- Current status: non-executing `ProgramEvaluator` stub and wiring added; sandbox execution pending.
+- Phase 3:
+  - UI polish (use existing WS payloads), docs/examples, ablation scripts.
+
+## Acceptance Criteria
+
+- Can create an optimization with `optimizer_type="mcts"` that:
+  - Runs to completion within token budget and iterations.
+  - Emits WS updates and persists per-simulation iterations via `record_optimization_iteration`.
+  - Returns `optimized_prompt_id` with final metrics ≥ initial metrics on a seeded sample test set.
+- Input validation rejects invalid strategy params with clear errors.
+- No breaking changes to other strategies or endpoints.
+- Metrics exposed without errors; logs do not include secrets.
+  - Current: WS progress is live; metrics to be added.
+
+## Test Plan
+
+- Unit (marker: `unit`):
+  - UCT selection favors higher UCT child; tie-breaking stable.
+  - Score binning deduplicates siblings correctly.
+  - Early stop triggers on no-improvement and budget exhaustion.
+- Integration (marker: `integration`):
+  - Create → run → complete MCTS optimization against 3-5 toy test cases; best_reward improves vs baseline prompt.
+  - WS: receive progress and completion events.
+  - Endpoint validation rejects out-of-range params.
+- (Phase 2) Security:
+  - ProgramEvaluator timeouts; no file/network; unsafe imports blocked.
+
+## Risks & Mitigations
+
+- Token overuse: enforce `token_budget`, use cheap scorer, early stop.
+- Noisy scorer: smooth via averaging across 2-3 low-cost calls or use heuristics (length, variable coverage).
+- Latency: cap simulations; stream partial progress; allow cancellation via existing cancel endpoint.
+- Sandboxing complexity (v2): keep optional; ship MVP without code exec.
+
+## Open Questions
+
+- Persist full MCTS tree for UI? MVP: store compact summaries in optimization `result` and per-iteration records.
+- Preferred small model for scoring (OpenAI mini vs local)? Default to configured “fast” provider; make configurable per project.
+- Decomposer LLM-based vs heuristic rule-based? MVP: heuristic with optional LLM assist when budget allows.
+
+## Dependencies
+
+- Reuse existing infra: PromptExecutor, TestRunner, JobManager, EventBroadcaster, DB methods.
+- No new external libs for MVP; (optional) sandbox may need OS-level constraints if implemented.
+
+## Documentation
+
+- This PRD (Docs/Design/Prompt_Studio_MCTS_Sequence_Optimization_PRD.md).
+- API docs: extend Prompt Studio Optimization section with mcts strategy params and examples.
+- Add examples under `Docs/Examples/PromptStudio/mcts/` (follow-up task).
+
+## Milestones
+
+- M1 (Week 1): Schema validation, `MctsOptimizer` skeleton, heuristic scorer/decomposer, integration with `OptimizationEngine`, docs. (Done)
+- M2 (Week 2): WS streaming (Done), metrics, cost controls, integration tests. Ship MVP.
+- M3 (Week 3, optional): `ProgramEvaluator` behind feature flag, sandbox, tests.

+# Watchlists v1 - Implementation Plan (Bridge PRD)
+
+This plan tracks the remaining work to wrap Watchlists v1 per the Bridge PRD. Each stage lists goals, success criteria, and concrete test points. Update Status as work progresses.
+
+## Current Status (snapshot)
+- Core endpoints and WebUI implemented (filters CRUD, include-only gating, OPML import/export with group filter, preview, global runs, CSV exports).
+- Tests added for CSV exports, OPML large/tag cases, global runs pagination/isolation, preview, YouTube normalization edges, and rate-limit headers (strict mode).
+- Docs updated (API: runs/tallies/OPML examples/gating table; Product PRD; Ops runbook). 410 shim for legacy Subscriptions is live.
+
+## Remaining To-Do (v1 sign-off)
+- Verify “Runs” role gating against the real user object in your auth setup; otherwise rely on env toggles (`NEXT_PUBLIC_RUNS_REQUIRE_ADMIN`).
+- Optional: widen YouTube normalization edge tests (keep policy of 400 for handles/vanity).
+- Optional: add include_tallies aggregation mode to global runs CSV if admins need it.
+- Optional: deterministic rate-limit header assertions under a non-test configuration for OPML import and filters endpoints.
+
+## Stage 1: QA, Deprecations, and Docs Finalization
+**Goal**: Ship Phase B wrap-up with hardened inputs, finalized docs, and visible metrics.
+
+**Success Criteria**
+- API docs include `GET /api/v1/watchlists/runs`, `include_tallies` for Run Detail, and OPML export `group` filter.
+- Deprecation path finalized: all `/api/v1/subscriptions/*` return 410 with Link header and docs + release notes updated.
+- YouTube normalization hardened (handles/vanity accepted → canonical; normalization headers logged in diagnostics).
+- Admin Runs view shows per-run counters and supports CSV/JSON export.
+
+**Tests**
+- OPML export filtering: group, group+tag, type interactions.
+  - tldw_Server_API/tests/Watchlists/test_opml_export_group.py
+- YouTube normalization: create/update/bulk non-canonical inputs → normalized URL + headers.
+  - tldw_Server_API/tests/Watchlists/test_youtube_normalization_more.py
+- Run Detail tallies toggle returns `filter_tallies` when `include_tallies=true` and totals always present.
+  - tldw_Server_API/tests/Watchlists/test_run_detail_filters_totals.py
+- Optional: rate-limit headers present under non-test mode for OPML import and filters endpoints.
+  - tldw_Server_API/tests/Watchlists/test_rate_limit_headers_optional.py
+
+**Status**: Completed
+
+---
+
+## Stage 2: Migration Tooling (Subscriptions → Watchlists)
+**Goal**: Provide an easy migration path from legacy Subscriptions to Watchlists.
+
+**Success Criteria**
+- CLI/import helper exports legacy Subscriptions as OPML + JSON filters and creates mapped Watchlists sources/jobs with filters.
+- Dry-run mode prints planned changes without writing.
+- Playbook doc (mapping table and fallbacks) linked from README/Docs.
+
+**Tests**
+- Unit: mapping from legacy fields → `{source, job, filters}` payloads (edge cases, unknown fields).
+  - Helper_Scripts/tests/test_subscriptions_mapping.py
+- Integration: sample legacy export → import → verify created sources/jobs/filters; dry-run yields no DB writes.
+  - tldw_Server_API/tests/Watchlists/test_migration_import_cli.py
+
+**Status**: Not Required (Subscriptions never shipped to prod; use OPML import)
+
+---
+
+## Stage 3: v1 UX Enhancements
+**Goal**: Improve usability with preview/dry-run, richer filter editing, and stronger runs browsing.
+
+**Success Criteria**
+- Preview/dry-run endpoint (no ingestion) returns candidate items with matched filter metadata.
+  - `POST /api/v1/watchlists/jobs/{id}/preview?limit=…` (or equivalent) returns items + reason (filter id/type/action).
+- Filters editor supports reorder, enable/disable, presets, and advanced JSON textarea.
+- Runs UI: global runs search/pagination, per-job pagination, tallies toggle, download log, link to items scoped by run.
+
+**Tests**
+- API: preview returns candidates and `matched_filter` indications; respects include-only gating.
+  - tldw_Server_API/tests/Watchlists/test_preview_endpoint.py
+- UI (lightweight): validate presence of editor controls and basic input constraints (IDs numeric, non-negative).
+  - tldw-frontend/tests/watchlists_ui_smoke.test.ts
+
+**Status**: Completed
+
+---
+
+## Stage 4: Output & Delivery Expansions
+**Goal**: Polish template authoring and wire delivery channels (email, Chatbook), with optional audio briefs.
+
+**Success Criteria**
+- Templates: CRUD with name/description/version; selectable per job; version history retained.
+- Delivery: email and Chatbook paths configurable per job (subject/body, conversation target), with success/failure surfaced in run outputs.
+- Optional: audio brief via TTS for small result sets.
+
+**Tests**
+- Unit: template rendering with variables and version selection.
+  - tldw_Server_API/tests/Watchlists/test_templates_rendering.py
+- Integration: email + Chatbook delivery using mocks; run artifacts record delivery status and IDs.
+  - tldw_Server_API/tests/Watchlists/test_delivery_integrations.py
+- Optional: TTS brief generated and attached when item count below threshold.
+  - tldw_Server_API/tests/Watchlists/test_tts_brief_optional.py
+
+**Status**: Partially Completed (templates/output delivery paths exist; advanced authoring/versioning and optional TTS are future work)
+
+---
+
+## Stage 5: Scale & Reliability
+**Goal**: Improve scheduling controls, dedup/seen visibility, and performance at higher scale.
+
+**Success Criteria**
+- Scheduler UX: concurrency, per-host delay, backoff controls; show next/last run per job.
+- Dedup/seen: expose counts and reset tools per source; admin tooling to inspect/clear.
+- Performance: validated on large filter sets, many sources, and long OPML imports; document limits and recommended settings.
+
+**Tests**
+- Scheduling: concurrency/backoff honored; next/last timestamps updated correctly.
+  - tldw_Server_API/tests/Watchlists/test_scheduler_controls.py
+- Dedup/seen: counts accurate; reset clears state safely; no duplicate ingestion after reset.
+  - tldw_Server_API/tests/Watchlists/test_dedup_seen_tools.py
+- Performance (sanity): marked `perf` scenarios for large inputs complete within budget.
+  - tldw_Server_API/tests/Watchlists/test_perf_scenarios.py
+- Rate-limit headers deterministic under non-test mode with configured backend.
+  - tldw_Server_API/tests/Watchlists/test_rate_limit_headers_strict.py
+
+**Status**: In Progress (scheduler/dedup tooling are broader platform items)
+
+---
+
+## Notes
+- Include-only gating: default can be set per-org (and via env); tests should cover both job-flag and org-default paths.
+- Keep tests deterministic; mock external services (feeds, email, Chatbook, TTS). Mark performance tests with `@pytest.mark.perf`.
+- Update Docs/Published/API-related/Watchlists_API.md and Docs/Published/RELEASE_NOTES.md alongside code changes.
+
+Checklist (quick)
+- [x] CSV export tests (global/by-job + tallies; headers/rows)
+- [x] OPML export tests (multi-group OR + tag AND; large set; tag case-insensitivity)
+- [x] Global runs API tests (q search, pagination boundaries, user isolation)
+- [x] Docs polish (gating table, OPML examples, regex flags note, Admin Items/CSV)
+- [x] Preview endpoint tests (RSS + site; include-only on/off)
+- [x] Rate-limit headers strict test (non-test mode via monkeypatch)
+- [ ] Verify Runs role gating against real user object (or disable via env)
+- [ ] Optional: CSV include_tallies aggregation mode (API + UI)

 - If you run the server in mock mode for benchmarking (`CHAT_FORCE_MOCK=1`), the upstream LLM panels still work since metrics are recorded by the gateway (decorators and usage tracker).

+# TTS Providers Getting Started Guide
+
+This guide helps new operators bring text-to-speech (TTS) online inside `tldw_server`. It walks through the supported providers (cloud + local), required dependencies, configuration files, and verification commands so you can decide which adapter to enable and confirm it works end to end.
+
+## Key Files & Paths
+- `tldw_Server_API/app/core/TTS/tts_providers_config.yaml` — canonical provider settings + priority list.
+- `Config_Files/config.txt` — optional INI overrides (e.g., `[TTS-Settings]` block).
+- `tldw_Server_API/app/core/TTS/adapters/` — implementation for each backend.
+- `tldw_Server_API/app/core/TTS/TTS-README.md` — deep dive on architecture + adapter matrix.
+
+## Quick Reference (Choose Your Provider)
+
+| Provider | Type | Install / Extras | Voice Cloning | Reference |
+| --- | --- | --- | --- | --- |
+| OpenAI `tts-1` | Hosted API | `OPENAI_API_KEY` | No | [Getting Started](../Getting-Started-STT_and_TTS.md#option-a--openai-tts-hosted) |
+| ElevenLabs | Hosted API | `ELEVENLABS_API_KEY` | Yes (via ElevenLabs voices) | [TTS Setup Guide](../STT-TTS/TTS-SETUP-GUIDE.md#commercial-providers) |
+| Kokoro ONNX | Local ONNX | `pip install -e ".[TTS_kokoro_onnx]"` + `espeak-ng` | No | [Getting Started](../Getting-Started-STT_and_TTS.md#option-b--kokoro-tts-local-onnx) |
+| NeuTTS Air | Local hybrid | `pip install -e ".[TTS_neutts]"` + `espeak-ng` | **Required** (reference audio + text) | [NeuTTS Runbook](../STT-TTS/NEUTTS_TTS_SETUP.md) |
+| Chatterbox | Local PyTorch | `pip install -e ".[TTS_chatterbox]"` (+ `.[TTS_chatterbox_lang]` for multilingual) | Yes (5–20 s) | [Chatterbox Runbook](../Published/User_Guides/Chatterbox_TTS_Setup.md) |

+
+> Tip: Keep cloud providers (`openai`, `elevenlabs`) high in `provider_priority` for instant results, and add local fallbacks underneath.
+
+## Baseline Prerequisites
+1. **Install the project**  
+   ```bash
+   pip install -e .
+   ```
+   Add extras per provider (see table above).
+2. **System packages**
+   - FFmpeg (`brew install ffmpeg` or `apt-get install -y ffmpeg`)
+   - eSpeak NG for phonemizer-backed models (`brew install espeak-ng` / `apt-get install -y espeak-ng`)
+3. **Model cache helpers**  
+   `pip install huggingface-hub` and log in if you need gated repos.
+4. **Runtime**  
+   Start the API:  
+   ```bash
+   python -m uvicorn tldw_Server_API.app.main:app --reload
+   ```
+   Note the printed `X-API-KEY` when running in single-user mode.
+
+## Recommended Setup Flow
+1. **Pick providers** you care about and install their extras.
+2. **Download models** proactively (use `huggingface-cli download ... --local-dir ...` for offline hosts).
+3. **Edit `tts_providers_config.yaml`**  
+   - Enable the provider, point to local paths, and adjust `device`, `sample_rate`, etc.  
+   - Adjust `provider_priority` so preferred backends run first.
+4. **Optional overrides** in `Config_Files/config.txt` (`[TTS-Settings]`) if you need environment-specific toggles.
+5. **Set secrets/env vars** (API keys, `TTS_AUTO_DOWNLOAD`, device hints).
+6. **Restart the server** and watch logs for `adapter initialized`.
+7. **Verify** with `curl` (samples below) or via the WebUI ➜ Audio ➜ TTS tab.
+
+---
+
+## Hosted Providers
+
+### OpenAI
+1. Export your key or add it to `config.txt`:
+   ```bash
+   export OPENAI_API_KEY=sk-...
+   ```
+2. (Optional) Change the default model (`tts-1-hd`) or base URL (self-hosted proxies) inside `tts_providers_config.yaml`.
+3. Verify:
+   ```bash
+   curl -sS -X POST http://127.0.0.1:8000/api/v1/audio/speech \
+     -H "X-API-KEY: $SINGLE_USER_API_KEY" \
+     -H "Content-Type: application/json" \
+     -d '{"model":"tts-1","voice":"alloy","input":"Hi from OpenAI","response_format":"mp3"}' \
+     --output openai.mp3
+   ```
+
+### ElevenLabs
+1. Set `ELEVENLABS_API_KEY` and enable the provider in the YAML:
+   ```yaml

+## Local Providers
+
+Each section highlights installation, configuration, and a smoke test.
+
+### Kokoro ONNX
+- **Install**: `pip install -e ".[TTS_kokoro_onnx]"` and `brew install espeak-ng` (or platform equivalent). Export `PHONEMIZER_ESPEAK_LIBRARY` if the library is in a non-standard path.
+- **Models**: place `kokoro-v0_19.onnx` and `voices.json` under `models/kokoro/`.
+- **Config**:
+  ```yaml
+  providers:
+    kokoro:
+      enabled: true
+      use_onnx: true
+      model_path: "models/kokoro/kokoro-v0_19.onnx"
+      voices_json: "models/kokoro/voices.json"
+      device: "cpu"  # or "cuda"
+  ```
+- **Verify**:
+  ```bash
+  curl -s http://127.0.0.1:8000/api/v1/audio/voices/catalog \
+    -H "X-API-KEY: $SINGLE_USER_API_KEY" | jq '.kokoro'
+  curl -sS -X POST http://127.0.0.1:8000/api/v1/audio/speech \
+    -H "X-API-KEY: $SINGLE_USER_API_KEY" \
+    -H "Content-Type: application/json" \
+    -d '{"model":"kokoro","voice":"af_bella","input":"Local Kokoro test","response_format":"mp3"}' \
+    --output kokoro.mp3
+  ```
+
+### NeuTTS Air
+- **Install**: `pip install -e ".[TTS_neutts]"`; ensure `espeak-ng` is installed for phonemizer support.
+- **Config**:
+  ```yaml
+  providers:
+    neutts:
+      enabled: true
+      backbone_repo: "neuphonic/neutts-air"          # or GGUF variant for streaming
+      backbone_device: "cpu"
+      codec_repo: "neuphonic/neucodec"
+      codec_device: "cpu"
+  ```
+- **Voice cloning**: every request must include a base64 `voice_reference` clip (3–15 s) plus `extra_params.reference_text` that exactly matches the spoken content.
+- **Verify**: use the sample curl from [NeuTTS Runbook](../STT-TTS/NEUTTS_TTS_SETUP.md) and confirm the WAV plays back.
+
+### Chatterbox
+- **Install**: `pip install -e ".[TTS_chatterbox]"`; add `.[TTS_chatterbox_lang]` if you plan to enable `use_multilingual`. The repo vendors a `chatterbox/` package, so no extra clone is needed.
+- **Models**: cache `ResembleAI/chatterbox` locally with `huggingface-cli download ...`.
+- **Config**:
+  ```yaml
+  providers:
+    chatterbox:
+      enabled: true
+      device: "cuda"
+      use_multilingual: false
+      disable_watermark: true
+      target_latency_ms: 200
+  ```
+- **Voice cloning**: send `voice_reference` (5–20 s, 24 kHz) and optional `emotion` + `emotion_intensity` to tune delivery.
+- **Reference**: see [Chatterbox Runbook](../Published/User_Guides/Chatterbox_TTS_Setup.md) for streaming examples and troubleshooting.
+
+### VibeVoice
+- **Install**: `pip install -e ".[TTS_vibevoice]"`; clone the upstream repo into `libs/VibeVoice` and `pip install -e .` there. Optional: `bitsandbytes`, `flash-attn`, `ninja` for CUDA optimizations.
+- **Config**:
+  ```yaml
+  providers:
+    vibevoice:
+      enabled: true
+      model_path: "microsoft/VibeVoice-1.5B"
+      device: "cuda"
+      use_quantization: true
+      voices_dir: "./voices"
+      speakers_to_voices:
+        "1": "en-Alice_woman"
+  ```
+- **Voice cloning**: drop samples into `voices_dir`, upload via API, or send `voice_reference`. Use `extra_params.speakers_to_voices` to map scripted speakers to files or uploaded IDs.
+- **Reference**: [VibeVoice Getting Started](../STT-TTS/VIBEVOICE_GETTING_STARTED.md).
+
+### Higgs Audio V2
+- **Install**: `pip install -e ".[TTS_higgs]"` and install the upstream repo (`git clone https://github.com/boson-ai/higgs-audio && pip install -e .`).
+- **Config**:
+  ```yaml
+  providers:
+    higgs:
+      enabled: true
+      model_path: "bosonai/higgs-audio-v2-generation-3B-base"
+      tokenizer_path: "bosonai/higgs-audio-v2-tokenizer"
+      device: "cuda"
+      use_fp16: true
+  ```
+- **Voice cloning**: accepts 3–10 s voice samples at 24 kHz (WAV/MP3/FLAC). Include `voice_reference` + `voice` = `"clone"`.
+- **Reference**: [Higgs section](../STT-TTS/TTS-SETUP-GUIDE.md#higgs-audio-v2-setup).
+
+### Dia
+- **Install**: `pip install torch torchaudio transformers accelerate nltk spacy` plus `python -m spacy download en_core_web_sm`.
+- **Config**:
+  ```yaml
+  providers:
+    dia:
+      enabled: true
+      model_path: "nari-labs/dia"
+      device: "cuda"
+      auto_detect_speakers: true
+      max_speakers: 5
+  ```
+- **Usage**: best for dialogue transcripts (`Speaker 1:`, `Speaker 2:`). Supports voice cloning with per-speaker references.
+
+### IndexTTS2
+- **Install/Assets**: place model checkpoints + configs under `checkpoints/index_tts2/`. Follow the adapter instructions in [TTS-README](../../tldw_Server_API/app/core/TTS/TTS-README.md#indextts2-adapter) for expected filenames.
+- **Config**:
+  ```yaml
+  providers:
+    index_tts:
+      enabled: true
+      model_dir: "checkpoints/index_tts2"
+      cfg_path: "checkpoints/index_tts2/config.yaml"
+      device: "cuda"
+      use_fp16: true
+      interval_silence: 200
+  ```
+- **Hardware**: plan for 12 GB+ VRAM. Every request must include a `voice_reference` clip (zero-shot cloning).
+
+---
+
+## Voice Management & Reference Audio
+- Upload reusable samples:
+  ```bash
+  curl -sS -X POST http://127.0.0.1:8000/api/v1/audio/voices/upload \
+    -H "X-API-KEY: $SINGLE_USER_API_KEY" \
+    -F "file=@/path/to/voice.wav" \
+    -F "name=Frank" \
+    -F "provider=vibevoice"
+  ```
+  The API returns a `voice_id`; reuse it via `"voice": "custom:"`.
+- Inline references: set `"voice_reference": ""` directly on the TTS request.
+- Duration & quality (see `tldw_Server_API/app/core/TTS/TTS-VOICE-CLONING.md`):
+  - Higgs: 3–10 s @ 24 kHz, mono.
+  - Chatterbox: 5–20 s @ 24 kHz, mono.
+  - VibeVoice: 3–30 s @ 22.05 kHz (adapter resamples).
+  - NeuTTS: 3–15 s @ 24 kHz **plus** matching `reference_text`.
+  - IndexTTS2: 3–15 s @ 24 kHz, or precomputed `ref_codes`.
+

+## Auto-Download & Environment Switches
+| Variable | Purpose |
+| --- | --- |
+| `TTS_AUTO_DOWNLOAD` | Global toggle for all local providers (`1` to allow HF downloads). |
+| `KOKORO_AUTO_DOWNLOAD`, `HIGGS_AUTO_DOWNLOAD`, `DIA_AUTO_DOWNLOAD`, `CHATTERBOX_AUTO_DOWNLOAD`, `VIBEVOICE_AUTO_DOWNLOAD` | Per-provider overrides when you need strict offline mode. |
+| `TTS_DEFAULT_PROVIDER` / `TTS_DEFAULT_VOICE` | Overrides the provider/voice when the client omits them. |
+| `TTS_DEVICE` | Forces a device hint (e.g., `cuda`, `cpu`) across adapters that respect it. |
+| `TTS_STREAM_ERRORS_AS_AUDIO` | When `1`, embed adapter errors into the stream (OpenAI compatibility); default `0` for normal HTTP errors. |

+
+## Verification Checklist
+1. **Provider discovery**
+   ```bash
+   curl -s http://127.0.0.1:8000/api/v1/audio/providers \
+     -H "X-API-KEY: $SINGLE_USER_API_KEY" | jq
+   ```
+2. **Voice catalog**
+   ```bash
+   curl -s http://127.0.0.1:8000/api/v1/audio/voices/catalog \
+     -H "X-API-KEY: $SINGLE_USER_API_KEY" | jq
+   ```
+3. **Synthesis smoke test** (replace `model` + `voice` per provider):
+   ```bash
+   curl -sS -X POST http://127.0.0.1:8000/api/v1/audio/speech \
+     -H "X-API-KEY: $SINGLE_USER_API_KEY" \
+     -H "Content-Type: application/json" \
+     -d '{"model":"kokoro","voice":"af_bella","input":"Hello from tldw_server","response_format":"mp3","stream":true}' \
+     --output tts-test.mp3
+   ```
+4. **WebUI**: Visit `http://127.0.0.1:8000/webui/#/audio` ➜ pick provider ➜ synthesize sample text.
+
+---
+
+## Troubleshooting Cheatsheet
+- **`ImportError` / missing modules** — re-run the correct extra install (e.g., `pip install -e ".[TTS_vibevoice]"`).
+- **Auto-download blocked** — set `TTS_AUTO_DOWNLOAD=0` (or per provider) and pre-populate `models/` via `huggingface-cli download`.
+- **`eSpeak` not found** — install `espeak-ng`; on macOS export `PHONEMIZER_ESPEAK_LIBRARY=/opt/homebrew/lib/libespeak-ng.dylib`.
+- **CUDA OOM** — enable quantization (VibeVoice), lower `vibevoice_variant`, or move the provider lower in `provider_priority` so lighter backends run first.
+- **Voice cloning rejects sample** — ensure duration/sample rate matches provider requirements and send mono audio.
+- **401/403** — confirm `X-API-KEY` header (single-user) or Bearer JWT (multi-user) plus upstream API keys.
+- **Adapter marked unhealthy** — see logs for circuit-breaker status; restart the server or wait for `performance.adapter_failure_retry_seconds` to elapse.

+# Test Gates Implementation
+
+Purpose: establish a pragmatic, long‑term approach to keep unit tests fast and deterministic by lazily initializing heavy subsystems and gating their route imports. This prevents timeouts/hangs caused by import‑time side effects (e.g., connection pools, background threads) while preserving full functionality for opt‑in integration suites and production.
+
+## Summary
+
+- Make heavy subsystems lazy: no connections/threads at import time.
+- Gate heavy routers behind environment/config toggles and import inside those gates.
+- Default tests to a minimal app profile; provide opt‑in markers/env for heavy suites.
+- Harmonize `TEST_MODE` semantics and use small pool sizes under tests.
+
+Targets (initial):
+- Evaluations (connection pool + webhook manager)
+- Jobs/metrics workers that start at app startup
+- Any router with heavy import‑time work (e.g., OCR/VLM only if needed)
+
+## Goals & Non‑Goals
+
+Goals
+- Fast unit tests by default (< a few seconds per file) without rewriting tests.
+- Deterministic startup/teardown in TestClient.
+- Simple, explicit switches to run heavy integration suites locally and in CI.
+
+Non‑Goals
+- Changing production behavior when routes are enabled.
+- Removing features; this is about initialization timing and control.
+
+## Design Overview
+
+1) Lazy singletons for heavy managers
+- Replace module‑level globals with getters that construct on first use.
+- Example (Evaluations):
+  - Before: `connection_manager = EvaluationsConnectionManager()` at import.
+  - After: `@lru_cache(maxsize=1) def get_connection_manager(...): return EvaluationsConnectionManager(...)`.
+  - Update helpers: `get_connection() -> get_connection_manager().get_connection()`.
+- Provide `shutdown_*_if_initialized()` helpers that no‑op if never created.
+
+2) Route import gating (main app)
+- Import heavy routers only inside `route_enabled("…")` gates, right before `include_router`.
+- Use existing route policy from config/env (`API-Routes` in `config.txt`, `ROUTES_DISABLE`, `ROUTES_ENABLE`).
+- Effect: if a route is disabled, its module is not imported and cannot trigger heavy work.
+
+3) Minimal test profile by default
+- In tests, set `MINIMAL_TEST_APP=1` and extend `ROUTES_DISABLE` to include heavy keys (e.g., `evaluations`) unless explicitly opted‑in.
+- Provide pytest marker/fixture to enable heavy routes for specific tests/suites.
+
+4) TEST_MODE normalization and pool sizing
+- Normalize truthiness across `TEST_MODE` and `TLDW_TEST_MODE` to {"1","true","yes","y","on"}.
+- Under tests, use small pool sizes/timeouts to reduce overhead (e.g., pool_size=1, max_overflow=2, timeout=5) for subsystems like Evaluations.
+
+## Environment & Config Toggles
+
+Config file: `tldw_Server_API/Config_Files/config.txt` section `[API-Routes]`
+- `stable_only = true|false` (default is false unless configured or overridden by env)
+- `disable = a,b,c`
+- `enable = x,y,z`
+- `experimental_routes = k1,k2`
+
+Environment variables (precedence > config.txt):
+- `ROUTES_STABLE_ONLY`      — same as `stable_only`.
+- `ROUTES_DISABLE`          — comma/space list of route keys to disable.
+- `ROUTES_ENABLE`           — comma/space list of route keys to force‑enable.
+- `ROUTES_EXPERIMENTAL`     — extend experimental list (affects `stable_only`).
+- `MINIMAL_TEST_APP`        — enables minimal test app profile (fast startup; selective routers).
+- `ULTRA_MINIMAL_APP`       — health‑only profile (diagnostics).
+- `TEST_MODE` / `TLDW_TEST_MODE` — unified test flags; treat truthy values as {1,true,yes,y,on}.
+- `RUN_EVALUATIONS`         — opt‑in heavy Evaluations routes for tests/CI.
+
+Recommended test defaults:
+- `MINIMAL_TEST_APP=1`
+- `ROUTES_DISABLE=research,evaluations` (extend existing value without clobbering)
+- `TEST_MODE=1`
+
+Opt‑in heavy suite:
+- Set `RUN_EVALUATIONS=1` (fixture or job env) and remove `evaluations` from `ROUTES_DISABLE`.
+
+## Implementation Plan (Stages)
+
+Stage 1 — Design & Staging
+- Add this doc and an IMPLEMENTATION_PLAN.md (optional) summarizing stages and success criteria.
+
+Stage 2 — Lazy Singletons (Evaluations/Webhooks)
+- File: `tldw_Server_API/app/core/Evaluations/connection_pool.py`
+  - Replace global `connection_manager` with `get_connection_manager()` (lru_cache).
+  - Update `get_connection()` / `get_connection_async()` to call the getter.
+  - Add `shutdown_evaluations_pool_if_initialized()`.
+- File: `tldw_Server_API/app/core/Evaluations/webhook_manager.py`
+  - Provide `get_webhook_manager()` that constructs on first use.
+  - Ensure schema init runs only when manager is first used.
+- File: `tldw_Server_API/app/main.py`
+  - Use shutdown helper; stop accessing module globals directly.
+
+Stage 3 — Gate Heavy Router Imports
+- File: `tldw_Server_API/app/main.py`
+  - Move heavy router imports inside `if route_enabled("…"):` blocks.
+  - Include only when enabled; otherwise avoid importing the module at all.
+
+Stage 4 — Default Minimal Test Profile
+- File: `tldw_Server_API/tests/conftest.py`
+  - `os.environ.setdefault("MINIMAL_TEST_APP", "1")`.
+  - Extend `ROUTES_DISABLE` to include `evaluations` unless `RUN_EVALUATIONS=1`.
+- Add pytest marker `evaluations`; a session fixture toggles env accordingly for marked tests.
+
+- Stage 5 — TEST_MODE & Pool Sizing Harmonization
+- File: `tldw_Server_API/app/api/v1/API_Deps/rate_limiting.py` and related deps
+  - Accept truthy `TEST_MODE` / `TLDW_TEST_MODE` variants.
+- File: `tldw_Server_API/app/core/Evaluations/connection_pool.py`
+  - Use small pool sizes when `TEST_MODE` is truthy.
+
+Stage 6 — Docs & CI
+- Update project docs (this file + Development doc): usage of toggles and patterns.
+- CI: default unit job uses minimal profile; nightly/weekly job sets `RUN_EVALUATIONS=1`.
+
+## File/Code Pointers (initial)
+
+- Route gating helpers: `tldw_Server_API/app/core/config.py` (route policy functions)
+- App route inclusion: `tldw_Server_API/app/main.py` (import + include_router strategy)
+- Evaluations connection pool: `tldw_Server_API/app/core/Evaluations/connection_pool.py`
+- Evaluations webhook manager: `tldw_Server_API/app/core/Evaluations/webhook_manager.py`
+- Test client setup: `tldw_Server_API/tests/conftest.py`
+
+## Testing Strategy
+
+Unit tests (default minimal profile)
+- Ensure startup is fast and no heavy connections are created when routes disabled.
+- Verify `get_connection_manager()` lazily constructs and returns a singleton.
+- Verify rate limiting bypass respects all truthy `TEST_MODE`/`TLDW_TEST_MODE` forms.
+
+Opt‑in integration tests (`-m evaluations` or `RUN_EVALUATIONS=1`)
+- Confirm `/api/v1/evaluations/*` routes are present and functional.
+- Assert pools and background workers start/stop cleanly.
+
+Regression checks
+- With `ROUTES_DISABLE=evaluations`, importing `main.py` must not create Evaluations connections.
+- Shutdown helpers must not error if never initialized.
+
+## CI Guidance
+
+- Unit job (default)
+- Env: `MINIMAL_TEST_APP=1`, `TEST_MODE=1`, `ROUTES_DISABLE=research,evaluations` (merge with any existing value).
+- Run standard markers: `-m "not evaluations and not jobs"`.
+
+Evaluations job (opt‑in)
+- Env: `RUN_EVALUATIONS=1`, `MINIMAL_TEST_APP=0` or remove `evaluations` from `ROUTES_DISABLE`.
+- Run markers: `-m evaluations`.
+
+Jobs/other heavy suites (optional)
+- Maintain separate CI jobs with explicit env toggles, mirroring the pattern above.
+
+## Backward Compatibility & Migration
+
+- If any code imports Evaluations globals directly (e.g., `from …connection_pool import connection_manager`), add a temporary alias:
+  - Define a module‑level property that returns `get_connection_manager()` and log a deprecation warning.
+- Prefer dependency‑injection or accessor functions (`get_…()`) over importing singletons.
+
+## Risks & Mitigations
+
+- Hidden heavy imports remain elsewhere
+  - Mitigation: search for module‑level instantiation patterns; convert to lazy as needed.
+- Shutdown ordering issues in tests
+  - Mitigation: centralize shutdown via helpers and app lifespan; add session‑level teardown fixtures.
+
+## Operational Notes
+
+- This approach does not change production behavior when routes are enabled.
+- When debugging, you can temporarily disable lazy gating by enabling the routes to compare startup behavior.
+
+## Quick Verification
+
+1) Disable evaluations and run a single test

+export MINIMAL_TEST_APP=1
+export ROUTES_DISABLE="${ROUTES_DISABLE},evaluations"
+export TEST_MODE=1
+pytest -q tldw_Server_API/tests/WebScraping/test_webscraping_usage_events.py::test_webscrape_process_usage_event
+```
+Expect: fast startup, no Evaluations pool logs, test completes quickly.
+
+2) Enable evaluations for integration run
+```
+export RUN_EVALUATIONS=1
+unset MINIMAL_TEST_APP
+export ROUTES_DISABLE="${ROUTES_DISABLE//evaluations/}"
+pytest -m evaluations -q
+```
+Expect: evaluations routes loaded; pools created; graceful shutdown.
+
+Note: Some routes are force-enabled during tests by `route_enabled()` (workflows, sandbox, scheduler, mcp-unified, mcp-catalogs, jobs, personalization), independent of `ROUTES_DISABLE`. This avoids 404s in common test paths.
+
+Examples
+- Lazy getter with shutdown helper:
+  - `from functools import lru_cache`
+  - `@lru_cache(maxsize=1)`
+  - `def get_connection_manager(): return EvaluationsConnectionManager(...)`
+  - `def shutdown_evaluations_pool_if_initialized():` call `get_connection_manager().shutdown()` then `get_connection_manager.cache_clear()` if instantiated.
+- Import-within-gate pattern (in `main.py`):
+  - `if route_enabled("evaluations"):` then import and `app.include_router(...)`; otherwise log disabled.
+
+Contributor checklist for heavy modules
+- No import-time threads/connections or background tasks.
+- Provide a lazy `get_...()` accessor and a `shutdown_..._if_initialized()` helper.
+- Register a route key in `[API-Routes]` and honor `ROUTES_DISABLE`/`ROUTES_ENABLE`.
+- If tests are heavy, add a pytest marker and CI skip by default.

 ## Option B — Kokoro TTS (Local, ONNX)
-Offline TTS using Kokoro ONNX. Good quality and speed on CPU; better with GPU.
+Offline TTS using Kokoro ONNX. Good quality and fast on CPU; optional GPU via ONNX Runtime.
 
 1) Install dependencies
 ```bash
-pip install kokoro-onnx
+# Python packages (CPU)
+pip install onnxruntime kokoro-onnx phonemizer espeak-phonemizer huggingface-hub
+
+# Optional: GPU acceleration (replace onnxruntime above)
+pip install onnxruntime-gpu
+
+# System package for phonemizer (required):
 # macOS (Homebrew):
 brew install espeak-ng
-# Set the phonemizer library (adjust path per OS):
+# Ubuntu/Debian:
+sudo apt-get update && sudo apt-get install -y espeak-ng
+# Windows (PowerShell, example):
+#  - Install eSpeak NG (from https://github.com/espeak-ng/espeak-ng/releases)
+#  - Set PHONEMIZER_ESPEAK_LIBRARY to libespeak-ng.dll path
+
+# eSpeak NG is auto-detected on most systems. Point the phonemizer to the library only if needed
+# macOS (adjust if your Homebrew prefix differs)
 export PHONEMIZER_ESPEAK_LIBRARY=/opt/homebrew/lib/libespeak-ng.dylib
+# Linux example
+export PHONEMIZER_ESPEAK_LIBRARY=/usr/lib/x86_64-linux-gnu/libespeak-ng.so.1
+# Windows example (only if auto-detect fails)
+# set PHONEMIZER_ESPEAK_LIBRARY=C:\\Program Files\\eSpeak NG\\libespeak-ng.dll
 ```
-- Linux example: `/usr/lib/x86_64-linux-gnu/libespeak-ng.so.1`
 
 2) Download model files
-- Place files under a `models/` folder at repo root (example):
-  - `models/kokoro-v0_19.onnx`
-  - `models/voices.json`
+- Place files under a `models/` folder at the repo root (example paths below).
+- Recommended sources:
+  - ONNX: `onnx-community/Kokoro-82M-v1.0-ONNX-timestamped` (contains `onnx/model.onnx` and a `voices/` directory of voice styles)
+  - PyTorch (optional): `hexgrad/Kokoro-82M` (contains `kokoro-v1_0.pth`, `config.json`, and `voices/`)
+
+Examples
+```bash
+# Create a local directory
+mkdir -p models/kokoro
+
+# Option A: huggingface-cli (ONNX v1.0)
+pip install huggingface-hub
+huggingface-cli download onnx-community/Kokoro-82M-v1.0-ONNX-timestamped onnx/model.onnx --local-dir models/kokoro/
+huggingface-cli download onnx-community/Kokoro-82M-v1.0-ONNX-timestamped voices          --local-dir models/kokoro/
+
+# Option B: direct URLs for ONNX (if CLI unavailable)
+wget https://huggingface.co/onnx-community/Kokoro-82M-v1.0-ONNX-timestamped/resolve/main/onnx/model.onnx -O models/kokoro/onnx/model.onnx
+# Then download the voices/ directory assets from the same repo (or use huggingface-cli above)

 Troubleshooting
-- `kokoro_onnx library not installed`: `pip install kokoro-onnx`
-- `voices.json not found` or `model not found`: fix paths in YAML.
-- `eSpeak lib not found`: install `espeak-ng` and set `PHONEMIZER_ESPEAK_LIBRARY`.
+- Missing dependencies
+  - kokoro_onnx: `pip install kokoro-onnx`
+  - onnxruntime: `pip install onnxruntime` (or `onnxruntime-gpu`)
+  - phonemizer / espeak-phonemizer: `pip install phonemizer espeak-phonemizer`
+- `voices assets not found` or `model not found`: fix `voices` directory or model path in YAML.
+- `eSpeak lib not found`: install `espeak-ng` and set `PHONEMIZER_ESPEAK_LIBRARY` to the library path.
 - Adapter previously failed and won’t retry: we enable retry by default (`performance.adapter_failure_retry_seconds: 300`). Or restart the server after fixing assets.
 
 Notes
-- PyTorch variant: set `use_onnx: false` and provide a PyTorch model path; requires `torch` and optionally GPU/MPS.
+- PyTorch variant (hexgrad/Kokoro-82M): set `use_onnx: false`, set `model_path: models/kokoro/kokoro-v1_0.pth`, ensure `config.json` sits alongside it, and set `voice_dir: models/kokoro/voices`. Requires `torch` and a compatible Kokoro PyTorch package. Set `device` to `cuda` or `mps` if available.

 This guide helps new operators bring text-to-speech (TTS) online inside `tldw_server`. It walks through the supported providers (cloud + local), required dependencies, configuration files, and verification commands so you can decide which adapter to enable and confirm it works end to end.
 
+## YAML Quick Start
+
+Minimal configuration to get going. Save to `tldw_Server_API/app/core/TTS/tts_providers_config.yaml` (or use one of the supported locations).
+
+```yaml
+# Provider selection / fallback order
+provider_priority:

+  stream_errors_as_audio: false
+```
+
+Notes:
+- Local providers will not download model assets unless you explicitly set `auto_download: true` (or export `TTS_AUTO_DOWNLOAD=1` / `VIBEVOICE_AUTO_DOWNLOAD=1`).
+- You can override API keys and some settings via `Config_Files/config.txt` or environment variables.
