-**Claude Agent SDK only** — All AI interactions use `claude-agent-sdk` because it handles security hooks, tool permissions, and MCP server integration. Use `create_client()` from `core.client`, not `anthropic.Anthropic()` directly.
+**Vercel AI SDK only** — All AI interactions use the Vercel AI SDK v6 (`ai` package) via the TypeScript agent layer in `apps/desktop/src/main/ai/`. NEVER use `@anthropic-ai/sdk` or `anthropic.Anthropic()` directly. Use `createProvider()` from `ai/providers/factory.ts` and `streamText()`/`generateText()` from the `ai` package. Provider-specific adapters (e.g., `@ai-sdk/anthropic`, `@ai-sdk/openai`) are managed through the provider registry.
 
 **i18n required** — All frontend user-facing text uses `react-i18next` translation keys. Hardcoded strings in JSX/TSX break localization for non-English users. Add keys to both `en/*.json` and `fr/*.json`.
 
-**Platform abstraction** — Use the platform modules in `apps/frontend/src/main/platform/` or `apps/backend/core/platform/` instead of `process.platform` directly. CI tests all three platforms, and raw platform checks cause failures.

+## AI Agent Layer (`apps/desktop/src/main/ai/`)
+
+All AI agent logic lives in TypeScript using the Vercel AI SDK v6. This replaces the previous Python `claude-agent-sdk` integration.
+
+### Architecture Overview
+
+- **Provider Layer** (`providers/`) — Multi-provider support via `createProviderRegistry()`. Supports Anthropic, OpenAI, Google, Bedrock, Azure, Mistral, Groq, xAI, and Ollama. Provider-specific transforms handle thinking token normalization and prompt caching.
+- **Session Runtime** (`session/`) — `runAgentSession()` uses `streamText()` with `stopWhen: stepCountIs(N)` for agentic tool-use loops. Includes error classification (429/401/400) and progress tracking.
+- **Worker Threads** (`agent/`) — Agent sessions run in `worker_threads` to avoid blocking the Electron main process. The `WorkerBridge` relays `postMessage()` events to the existing `AgentManagerEvents` interface.
+- **Build Orchestration** (`orchestration/`) — Full planner → coder → QA pipeline. Parallel subagent execution via `Promise.allSettled()`.
+- **Tools** (`tools/`) — 8 builtin tools (Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch) defined with Zod schemas via AI SDK `tool()`.
+- **Security** (`security/`) — Bash validator, command parser, and path containment ported from Python with identical allowlist behavior.
+- **Config** (`config/`) — `AGENT_CONFIGS` registry (25+ agent types), phase-aware model resolution, thinking budgets.
+
+### Key Patterns
+
+```typescript
+// Agent session using streamText()
+import { streamText, stepCountIs } from 'ai';
+
+const result = streamText({
+  model: provider,
+  system: systemPrompt,
+  messages: conversationHistory,
+  tools: toolRegistry.getToolsForAgent(agentType),
+  stopWhen: stepCountIs(1000),
+  onStepFinish: ({ toolCalls, text, usage }) => {
+    progressTracker.update(toolCalls, text);
+  },
+});
+
+// Tool definition with Zod schema
+import { tool } from 'ai';
+import { z } from 'zod';
+
+const readTool = tool({
+  description: 'Read a file from the filesystem',
+  inputSchema: z.object({
+    file_path: z.string(),
+    offset: z.number().optional(),
+    limit: z.number().optional(),
+  }),
+  execute: async ({ file_path, offset, limit }) => { /* ... */ },
+});
+```

+
+**Sources:** OpenAI Codex source code (`github.com/openai/codex`, Rust codebase), CodexBar macOS app (`github.com/steipete/CodexBar`), Context7 Codex developer docs.
+
+### 1.1 Active Polling Endpoint
+
+```
+GET https://chatgpt.com/backend-api/wham/usage
+```
+
+Fallback (when base URL doesn't contain `/backend-api`):
+```
+GET {base_url}/api/codex/usage

+
+**Required Headers:**
+```http
+Authorization: Bearer <access_token>
+ChatGPT-Account-Id: <account_id>
+Content-Type: application/json
+Accept: application/json
+```
+
+- `access_token` — The OAuth access token from `auth.openai.com` (same token our `codex-oauth.ts` already obtains)
+- `account_id` — Account UUID from OAuth token data. Stored in `~/.codex/auth.json` under `tokens.account_id`. Optional per CodexBar ("when available") but may be required.

+
+- `primary_window` = 5h session (18000s). Maps to our `sessionPercent`.
+- `secondary_window` = Weekly (604800s = 7d). Maps to our `weeklyPercent`.
+- `reset_at` = Unix timestamp (seconds). Convert to ms for our `sessionResetTimestamp`/`weeklyResetTimestamp`.
+- `plan_type` values: `guest`, `free`, `go`, `plus`, `pro`, `free_workspace`, `team`, `business`, `education`, `quorum`, `k12`, `enterprise`, `edu`
+
+### 1.3 Passive Headers (From API Responses)
+
+Rate limit data is also returned in HTTP response headers on every `/v1/responses` call:
+
+```
+x-codex-primary-used-percent         → float (e.g., "25.0")
+x-codex-primary-window-minutes       → integer (e.g., "300" for 5h)
+x-codex-primary-reset-at             → unix timestamp seconds
+x-codex-secondary-used-percent       → float (weekly)
+x-codex-secondary-window-minutes     → integer
+x-codex-secondary-reset-at           → unix timestamp seconds
+x-codex-credits-has-credits          → "true" or "false"
+x-codex-credits-unlimited            → "true" or "false"
+x-codex-credits-balance              → decimal string e.g. "9.99"
+```
+
+SSE event type `codex.rate_limits` also carries this data inline in streaming responses.
+
+### 1.4 Token Details
+
+Our `codex-oauth.ts` already uses the correct flow:
+- **Client ID:** `app_EMoamEEZ73f0CkXaXp7hrann` (same as Codex CLI)
+- **Auth endpoint:** `https://auth.openai.com/oauth/authorize`
+- **Token endpoint:** `https://auth.openai.com/oauth/token`
+- **Scopes:** `openid profile email offline_access`
+- **Refresh:** `POST https://auth.openai.com/oauth/token` with `grant_type=refresh_token`
+
+**Missing:** `account_id` for the `ChatGPT-Account-Id` header. Options:
+1. Decode from the JWT access token
+2. Read from `~/.codex/auth.json` (`tokens.account_id`)
+3. Extract during OAuth token exchange (may be in response)
+4. Try without it first (optional per CodexBar docs)
+
+---
+
+## 2. Current System Architecture
+
+### 2.1 Two Parallel Account Systems
+
+The app has TWO account management systems that don't fully integrate:
+
+**System A: Legacy Claude Profile Manager (Main Process)**
+- `claude-profile-manager.ts` — Manages OAuth profiles, rate limits, usage, auto-swap
+- `claude-profiles.json` — Stores profiles with `activeProfileId`, `accountPriorityOrder`
+- `usage-monitor.ts` — Polls Anthropic's `/api/oauth/usage` endpoint every 30s
+- `token-refresh.ts` — Refreshes tokens via `console.anthropic.com/v1/oauth/token`
+- `rate-limit-detector.ts` — Detects rate limits, triggers auto-swap
+- `profile-scorer.ts` — Scores profiles by availability for auto-swap
+- **100% Anthropic-specific.** Only knows about Anthropic OAuth tokens, Anthropic endpoints, Anthropic keychain format.
+
+**System B: Multi-Provider Accounts (Renderer + Settings)**
+- `ProviderAccount[]` in `settings-store.ts` — All connected accounts (any provider)
+- `globalPriorityOrder: string[]` in AppSettings — Manual priority queue
+- `useActiveProvider()` hook — First account in priority order = active
+- **Provider-agnostic.** Works for all 10 providers. But has NO usage monitoring, NO auto-swap.
+
+**The gap:** System A handles usage monitoring + auto-swap but only for Anthropic. System B handles multi-provider accounts but has no usage awareness.
+
+### 2.2 Data Flow: Usage Polling
+
+```
+UsageMonitor.start() → 30s interval
+  ↓
+checkUsageAndSwap()
+  ├─ determineActiveProfile()           ← Hardcoded: defaults to anthropic baseUrl
+  ├─ getCredential()                    ← Hardcoded: reads from Anthropic keychain
+  │   └─ ensureValidToken(configDir)    ← Hardcoded: refreshes via Anthropic endpoint
+  ├─ fetchUsageViaAPI()                 ← Hardcoded: only allows anthropic/zai/zhipu domains
+  │   ├─ getUsageEndpoint(provider)     ← Only 3 providers configured
+  │   ├─ Add anthropic-specific headers ← if (provider === 'anthropic') add beta headers
+  │   └─ Parse response                ← Provider-specific normalization
+  ├─ emit('usage-updated')             → IPC 'claude:usageUpdated' → renderer
+  ├─ emit('all-profiles-usage-updated') → IPC 'claude:allProfilesUsageUpdated' → renderer
+  └─ checkThresholdsExceeded()
+     └─ performProactiveSwap()          ← Only swaps Anthropic profiles
+```
+
+### 2.3 Data Flow: Account Swapping
+
+**Manual swap (UI):**
+```
+User clicks account in UsageIndicator popover
+  → handleSwapAccount(accountId)
+  → setQueueOrder([accountId, ...rest])    ← Reorders globalPriorityOrder
+  → requestUsageUpdate()                   ← Refreshes usage display
+```
+
+**Automatic swap (rate limit hit):**
+```
+SDK operation fails with 429
+  → detectRateLimit(output)                ← Pattern: "Limit reached · resets..."
+  → recordRateLimitEvent(profileId)
+  → getBestAvailableProfileEnv()
+  → profileManager.setActiveProfile()      ← Only updates claude-profiles.json
+  → usageMonitor.getAllProfilesUsage()     ← Refreshes UI
+  ← Returns new profile env vars
+```
+
+**Problem:** Auto-swap updates `claude-profiles.json` but NOT `globalPriorityOrder`. The renderer's priority queue may be out of sync.
+
+### 2.4 UI Components
+
+| Component | What it shows | Provider-specific? |
+|---|---|---|
+| `AuthStatusIndicator` | Provider badge (OpenAI/Anthropic) + auth type label | Codex = green "Codex", Anthropic = orange "OAuth" |
+| `UsageIndicator` | Usage bars OR "Subscription" OR "Unlimited" | Anthropic OAuth = bars, Codex OAuth = "Subscription", API = "Unlimited" |
+| `ProviderAccountCard` | Account card in settings with usage bars | Shows usage bars only when `account.usage` populated (Anthropic only) |
+| `ProviderAccountsList` | All accounts grouped by provider | Generic, but re-auth routes differ per provider |
+| `AddAccountDialog` | OAuth flow + account creation | Different flows: Codex → `codexAuthLogin()`, Anthropic → `claudeAuthLoginSubprocess()` |
+| `ProviderSection` | Provider group with "Add" buttons | Button label: "Add Codex Subscription" vs "Add OAuth" |
+
+### 2.5 Type Naming
+
+Types use "Claude" prefix but are structurally generic:
+```typescript
+ClaudeUsageSnapshot    → { sessionPercent, weeklyPercent, resetTimestamps, profileId, ... }
+ClaudeUsageData        → { sessionUsagePercent, weeklyUsagePercent }
+ClaudeRateLimitEvent   → { type, hitAt, resetAt }
+ProfileUsageSummary    → { sessionPercent, weeklyPercent, availabilityScore, ... }
+AllProfilesUsage       → { activeProfile, allProfiles[], fetchedAt }
+```
+
+These types work perfectly for Codex data — same session/weekly model. No structural changes needed, just need to populate them.
+
+---
+
+## 3. Anthropic-Hardcoded Locations
+
+### 3.1 CRITICAL — Must Change
+
+| File | Line(s) | What's hardcoded | What to do |
+|---|---|---|---|
+| `usage-monitor.ts:45-49` | `ALLOWED_USAGE_API_DOMAINS` | Only `api.anthropic.com`, `api.z.ai`, `open.bigmodel.cn` | Add `chatgpt.com` |
+| `usage-monitor.ts:60-73` | `PROVIDER_USAGE_ENDPOINTS` | Only anthropic/zai/zhipu paths | Add `{ provider: 'openai', usagePath: '/wham/usage' }` |
+| `usage-monitor.ts:662,1069,1346,1359` | `baseUrl: 'https://api.anthropic.com'` | Hardcoded fallback for all OAuth profiles | Detect provider from account, use `chatgpt.com/backend-api` for Codex |
+| `usage-monitor.ts:1424` | `if (provider === 'anthropic')` adds beta headers | Anthropic-specific `anthropic-beta` header | Add `else if (provider === 'openai')` to add `ChatGPT-Account-Id` header |
+| `token-refresh.ts:31` | `ANTHROPIC_TOKEN_ENDPOINT = 'https://console.anthropic.com/v1/oauth/token'` | Only Anthropic refresh endpoint | Route to `auth.openai.com/oauth/token` for Codex |
+| `token-refresh.ts:37` | `CLAUDE_CODE_CLIENT_ID = '9d1c250a-...'` | Only Anthropic client ID | Use `app_EMoamEEZ73f0CkXaXp7hrann` for Codex |
+| `UsageIndicator.tsx:118` | `provider === 'anthropic' && authType === 'oauth'` | Only Anthropic gets usage bars | Add `\|\| provider === 'openai'` |
+
+### 3.2 MODERATE — Should Change
+
+| File | Line(s) | What's hardcoded | What to do |
+|---|---|---|---|
+| `usage-monitor.ts:1040-1072` | `determineActiveProfile()` | Returns `baseUrl: 'https://api.anthropic.com'` for all OAuth | Detect provider, return `chatgpt.com/backend-api` for Codex |
+| `credential-utils.ts` | Keychain service names | `"Claude Code-credentials"` | Codex tokens stored differently (file-based, not keychain) |
+| `usage-monitor.ts:1513` | `if (provider === 'zai' \|\| provider === 'zhipu')` | Provider-specific response unwrapping | Add Codex response parsing (different JSON structure) |
+| `rate-limit-detector.ts:14` | `RATE_LIMIT_PATTERN` | Claude-specific: `"Limit reached · resets..."` | Add Codex-specific patterns |
+| IPC channel names | `'claude:usageUpdated'`, `'claude:allProfilesUsageUpdated'` | "claude" prefix | Cosmetic — rename to `'usage:updated'` etc. (optional, low priority) |
+
+### 3.3 LOW PRIORITY — Nice to Have
+
+| Item | What | Why low priority |
+|---|---|---|
+| Type naming | `ClaudeUsageSnapshot` → `UsageSnapshot` | Structural refactor, types work as-is for Codex |
+| IPC method names | `requestUsageUpdate` returns `ClaudeUsageSnapshot` | Works fine, just naming |
+| `claudeProfileId` on `ProviderAccount` | Only used for Anthropic OAuth | Codex doesn't need it |
+
+---
+
+## 4. Provider-Agnostic Parts
+
+These components already work for any provider and need NO changes:
+
+| Component/Module | Why it's already generic |
+|---|---|
+| `profile-scorer.ts` | Scores by `billingModel`, usage thresholds, rate limit events — no provider checks |
+| `rate-limit-manager.ts` | Stores/checks rate limit events — pure data, no provider logic |
+| `operation-registry.ts` | Tracks running operations — no provider awareness |
+| `ProviderAccount` type | Has `provider` field, `billingModel`, `usage` — works for any provider |
+| `globalPriorityOrder` | Array of account IDs — provider-agnostic ordering |
+| `useActiveProvider()` hook | Returns first account in priority order — generic |
+| `ProviderAccountCard` | Shows usage bars when `account.usage` is populated — will work for Codex once data flows |
+| `AddAccountDialog` | Already has separate Codex OAuth flow |
+| `AuthStatusIndicator` | Already shows Codex-specific green badge |
+| All i18n keys | Codex-specific labels already exist |
+
+---
+
+## 5. Implementation Plan
+
+### Phase 1: Codex Usage Fetcher (Core)
+
+Create `apps/desktop/src/main/claude-profile/codex-usage-fetcher.ts`:
+
+```typescript
+// Responsibilities:
+// 1. Read Codex OAuth token (from our codex-auth.json)
+// 2. Read account_id (from ~/.codex/auth.json or JWT decode)
+// 3. Call GET https://chatgpt.com/backend-api/wham/usage
+// 4. Parse response into ClaudeUsageSnapshot format
+// 5. Handle 401 → refresh token via codex-oauth.ts
+// 6. Handle 403 → mark as needsReauthentication
+```
+
+**Key function:**
+```typescript
+async function fetchCodexUsage(accessToken: string, accountId?: string): Promise<ClaudeUsageSnapshot>
+```
+
+### Phase 2: Wire into Usage Monitor
+
+Modify `usage-monitor.ts`:
+
+1. Add `chatgpt.com` to `ALLOWED_USAGE_API_DOMAINS`
+2. Add Codex to `PROVIDER_USAGE_ENDPOINTS`
+3. Update `determineActiveProfile()` to detect Codex accounts from `globalPriorityOrder`
+4. Update `getCredential()` to read Codex OAuth token (from `codex-auth.json`)
+5. Update `fetchUsageViaAPI()` to handle Codex response format
+6. Add Codex-specific headers (`ChatGPT-Account-Id`)
+7. Add Codex response parsing (different JSON structure than Anthropic)
+
+### Phase 3: Token Refresh Routing
+
+Modify `token-refresh.ts` or create parallel Codex path:
+
+- When refreshing a Codex token, use `auth.openai.com/oauth/token` with Codex client ID
+- When refreshing an Anthropic token, use `console.anthropic.com/v1/oauth/token` with Claude client ID
+- Provider detection: check the account's `provider` field, or detect from token prefix
+
+### Phase 4: UI Updates
+
+1. `UsageIndicator.tsx:118` — Add `|| provider === 'openai'` to `hasUsageMonitoring`
+2. That's it — the rest of the UI already handles usage bars, reset times, multi-profile display generically
+
+### Phase 5: Auto-Swap for Codex
+
+1. Add Codex-specific rate limit patterns to `rate-limit-detector.ts`
+2. Codex returns `"codexErrorInfo": "UsageLimitExceeded"` on limit hit
+3. Auto-swap logic in `profile-scorer.ts` already works — it just needs usage data populated
+
+---
+
+## Appendix: Comparison Table
+
+| Aspect | Anthropic (Claude Code) | OpenAI (Codex) |
+|---|---|---|
+| **Usage endpoint** | `api.anthropic.com/api/oauth/usage` | `chatgpt.com/backend-api/wham/usage` |
+| **Auth header** | `Bearer <oauth_token>` | `Bearer <access_token>` + `ChatGPT-Account-Id` |
+| **Session window** | ~5h | Configurable (`limit_window_seconds`) |
+| **Weekly window** | 7 days | Configurable (`limit_window_seconds`) |
+| **Token source** | Keychain (`Claude Code-credentials`) | File (`codex-auth.json`) |
+| **Token refresh** | `console.anthropic.com/v1/oauth/token` | `auth.openai.com/oauth/token` |
+| **Client ID** | `9d1c250a-e61b-44d9-88ed-5944d1962f5e` | `app_EMoamEEZ73f0CkXaXp7hrann` |
+| **Passive tracking** | Not available | `x-codex-*` response headers |
+| **Rate limit error** | `"Limit reached · resets Dec 17..."` | `"codexErrorInfo": "UsageLimitExceeded"` |
+| **Profile isolation** | `~/.claude-profiles/{name}/` dirs | Single `codex-auth.json` file |
+| **Multi-account** | Multiple config dirs in keychain | Single file (no multi-account yet) |
+
+## Appendix: Caveats
+
+1. **Undocumented API** — `chatgpt.com/backend-api/wham/usage` is internal. The Codex CLI depends on it, so it's unlikely to break silently.
+2. **Account ID** — May be required. Test without it first. If needed, decode from JWT or read `~/.codex/auth.json`.
+3. **CORS** — Not an issue (Electron main process = Node.js).
+4. **Polling rate** — Unknown if OpenAI rate-limits `wham/usage`. Start conservatively (every 30-60s).
+5. **Multi-account Codex** — Codex CLI doesn't support multiple accounts. We store one token file. If user has multiple Codex accounts, they'd need to re-auth each time (unlike Anthropic which supports multiple config dirs).

+## 1. Design Philosophy and Competitive Positioning
+
+### Why Memory Is the Technical Moat
+
+Auto Claude positions as "more control than Lovable, more automatic than Cursor or Claude Code." Memory is the primary mechanism that delivers on this promise. Every session without memory forces agents to rediscover the codebase from scratch — re-reading the same files, retrying the same failed approaches, hitting the same gotchas. With a well-designed memory system, agents navigate the codebase like senior developers who built it.
+
+The accumulated value compounds over time:
+
+```
+Sessions 1-5:   Cold. Agent explores from scratch every session.
+                High discovery cost. No patterns established.
+
+Sessions 5-15:  Co-access graph built. Prefetch patterns emerging.
+                Gotchas accumulating. ~30% reduction in redundant reads.
+
+Sessions 15-30: Calibration active. QA failures no longer recur.
+                Workflow recipes firing at planning time.
+                Impact analysis preventing ripple bugs.
+                ~60% reduction in discovery cost.
+
+Sessions 30+:   The system knows this codebase. Agents navigate it
+                like senior developers who built it. Context token
+                savings measurable in the thousands per session.
+```
+
+### The Three-Tier Injection Model
+
+| Tier | When | Mechanism | Purpose |
+|------|------|-----------|---------|
+| Passive | Session start | System prompt + initial message injection | Global memories, module memories, workflow recipes, work state |
+| Reactive | Mid-session, agent-requested | `search_memory` tool in agent toolset | On-demand retrieval when agent explicitly needs context |
+| Active | Mid-session, system-initiated | `prepareStep` callback in `streamText()` | Proactive injection per step based on what agent just did |
+
+### Observer-First Philosophy
+
+The most valuable memories are never explicitly requested. They emerge from watching what the agent does — which files it reads together, which errors it retries, which edits it immediately reverts, which approaches it abandons. Explicit `record_memory` calls are supplementary, not primary.
+
+### Competitive Gap Matrix
+
+| Capability | Cursor | Windsurf | Copilot | Augment | Devin | Auto Claude V5 |
+|---|---|---|---|---|---|---|
+| Behavioral observation | No | Partial | No | No | No | Yes (17 signals) |
+| Co-access graph | No | No | No | No | No | Yes |
+| BM25 + semantic + graph hybrid | No | No | No | Partial | No | Yes |
+| Graph neighborhood boost | No | No | No | No | No | Yes (+7pp, unique) |
+| Cross-encoder reranking | No | No | No | No | No | Yes (local) |
+| AST-based chunking | Partial | No | No | No | No | Yes (tree-sitter) |
+| Contextual embeddings | No | No | No | No | No | Yes |
+| Active prepareStep injection | No | No | No | No | No | Yes |
+| Scratchpad-to-promotion gate | No | No | No | No | No | Yes |
+| Knowledge graph (3 layers) | No | No | No | No | No | Yes |
+| Same code path local + cloud | N/A | N/A | N/A | N/A | N/A | Yes (libSQL) |

+1. **Graph neighborhood boost** — 3-path hybrid retrieval that boosts results co-located in the knowledge graph. No competitor does this because none have a closure-table knowledge graph.
+2. **Behavioral observation** — watching what agents *do*, not what they say.
+3. **Active prepareStep injection** — the third tier that fires between every agent step.
+

+
+## 2. Infrastructure Architecture
+
+### The Core Design Decision: Turso/libSQL
+
+The single most important infrastructure decision is using **Turso/libSQL** (`@libsql/client`) as the memory database. This gives us identical query code for both local Electron and cloud web app deployments.
+
+```typescript
+// Free tier — Electron desktop, no login
+const db = createClient({ url: 'file:memory.db' });
+
+// Logged-in user — Electron with cloud sync
+const db = createClient({
+  url: 'file:memory.db',            // Local replica (fast reads)
+  syncUrl: 'libsql://project-user.turso.io',
+  authToken: convexAuthToken,
+  syncInterval: 60,                 // Sync every 60 seconds
+});
+
+// Web app (SaaS, Next.js) — no local file, pure cloud
+const db = createClient({
+  url: 'libsql://project-user.turso.io',
+  authToken: convexAuthToken,
+});
+```
+
+**The identical query**: FTS5, vector search, closure tables, co-access edges — same SQL works in all three modes.
+
+### Technology Stack
+
+| Concern | Technology | Notes |
+|---------|-----------|-------|
+| Memory storage | libSQL (`@libsql/client`) | Turso Cloud in cloud mode, in-process for local |
+| Vector search | `sqlite-vec` extension | `vector_distance_cos()`, `vector_top_k()` — works in libSQL |
+| BM25 search | FTS5 virtual table | Same in local and cloud; FTS5 not Tantivy (Tantivy is cloud-only) |
+| Knowledge graph | SQLite closure tables | Recursive CTEs work in libSQL |
+| Auth, billing, team UI | Convex + Better Auth | Real-time subscriptions, multi-tenancy, per-query scoping |
+| Embeddings (local) | Qwen3-embedding 4b/8b via Ollama | 1024-dim primary |
+| Embeddings (cloud/fallback) | OpenAI `text-embedding-3-small` | Request 1024-dim to match Qwen3 |
+| Reranking (local) | Qwen3-Reranker-0.6B via Ollama | Free, ~85-380ms latency |
+| Reranking (cloud) | Cohere Rerank API | ~$1/1K queries, ~200ms latency |
+| AST parsing | tree-sitter WASM (`web-tree-sitter`) | No native rebuild on Electron updates |
+| Agent execution | Vercel AI SDK v6 `streamText()` | Worker threads in Electron |
+
+### Deployment Modes
+
+```
+MODE 1: Free / Offline (Electron, no login)
+  └── libSQL in-process → memory.db
+      ├── All features work offline
+      ├── No cloud sync
+      └── Ollama for embeddings (or OpenAI fallback)
+
+MODE 2: Cloud User (Electron, logged in)
+  └── libSQL embedded replica → memory.db + syncUrl → Turso Cloud
+      ├── Same queries, same tables
+      ├── Reads from local replica (fast, offline-tolerant)
+      ├── Syncs to Turso Cloud every 60s
+      └── Convex for auth, team memory display, real-time UI
+
+MODE 3: Web App (Next.js SaaS)
+  └── libSQL → Turso Cloud directly (no local file)
+      ├── Same queries as Electron
+      ├── OpenAI embeddings (no Ollama in cloud)
+      ├── Convex for auth, billing, real-time features
+      └── Cohere Rerank API for cross-encoder reranking
+```
+
+### Convex Responsibilities (What Convex Is NOT Doing)
+
+Convex handles the **application layer** concerns, NOT memory storage:
+
+| Convex handles | libSQL/Turso handles |
+|----------------|---------------------|
+| Authentication (Better Auth) | All memory records |
+| Session management | Vector embeddings |
+| Team membership + roles | Knowledge graph nodes/edges |
+| Billing and subscription state | FTS5 BM25 index |
+| Real-time UI subscriptions | Co-access graph |
+| Project metadata | Observer scratchpad data |
+
+This clean split means Convex never touches the hot path of memory search. libSQL handles all data-intensive operations.
+
+### Multi-Tenancy with Turso
+
+Every user or project gets an isolated Turso database. This is Turso's database-per-tenant model:
+
+```
+user-alice-project-myapp.turso.io    → Alice's memory for "myapp"
+user-alice-project-backend.turso.io  → Alice's memory for "backend"
+user-bob-project-myapp.turso.io      → Bob's memory for "myapp"
+```
+
+No row-level security complexity. No cross-tenant leak risk. Each database is fully isolated.
+
+### Cost at Scale
+
+| Users | Turso (Scaler $25/month base) | Convex (Pro $25/month) | OpenAI Embeddings | Total |
+|-------|-------------------------------|------------------------|-------------------|-------|
+| 10 | $25 | $25 | <$1 | ~$51/mo |
+| 100 | ~$165 | $25 | ~$3 | ~$193/mo |
+| 500 | ~$1,200 | $25+ | ~$15 | ~$1,240/mo |
+
+At 500+ users, negotiate Turso Enterprise pricing. Writes dominate the bill; embedded replica reads are free.

+
+### Methodology Abstraction Layer
+
+All methodology phases map into six `UniversalPhase` values. The retrieval engine operates exclusively on `UniversalPhase`.
+
+```typescript
+interface MemoryMethodologyPlugin {
+  id: string;
+  displayName: string;
+  mapPhase(methodologyPhase: string): UniversalPhase;
+  resolveWorkUnitRef(context: ExecutionContext): WorkUnitRef;

+  ],
+};
+```
+

+
+## 4. Memory Observer
+
+The Observer is the passive behavioral layer. It runs on the main thread, tapping every `postMessage` event from worker threads. It never writes to the database during execution.
+
+### 17-Signal Taxonomy with Priority Scoring
+
+Signal value formula: `signal_value = (diagnostic_value × 0.5) + (cross_session_relevance × 0.3) + (1.0 - false_positive_rate) × 0.2`
+
+Signals with `signal_value < 0.4` are discarded before promotion filtering.
+
+| # | Signal Class | Score | Promotes To | Min Sessions |
+|---|-------------|-------|-------------|-------------|
+| 2 | Co-Access Graph | 0.91 | causal_dependency, prefetch_pattern | 3 |
+| 9 | Self-Correction | 0.88 | gotcha, module_insight | 1 |
+| 3 | Error-Retry | 0.85 | error_pattern, gotcha | 2 |
+| 16 | Parallel Conflict | 0.82 | gotcha | 1 |
+| 5 | Read-Abandon | 0.79 | gotcha | 3 |
+| 6 | Repeated Grep | 0.76 | module_insight, gotcha | 2 |
+| 13 | Test Order | 0.74 | task_calibration | 3 |
+| 7 | Tool Sequence | 0.73 | workflow_recipe | 3 |
+| 1 | File Access | 0.72 | prefetch_pattern | 3 |
+| 15 | Step Overrun | 0.71 | task_calibration | 3 |
+| 4 | Backtrack | 0.68 | gotcha | 2 |
+| 14 | Config Touch | 0.66 | causal_dependency | 2 |
+| 11 | Glob-Ignore | 0.64 | gotcha | 2 |
+| 17 | Context Token Spike | 0.63 | context_cost | 3 |
+| 10 | External Reference | 0.61 | module_insight | 3 |
+| 12 | Import Chase | 0.52 | causal_dependency | 4 |
+| 8 | Time Anomaly | 0.48 | (with correlation) | 3 |
+
+### Self-Correction Detection
+
+```typescript
+const SELF_CORRECTION_PATTERNS = [
+  /I was wrong about (.+?)\. (.+?) is actually/i,
+  /Let me reconsider[.:]? (.+)/i,
+  /Actually,? (.+?) (not|instead of|rather than) (.+)/i,
+  /I initially thought (.+?) but (.+)/i,
+  /Correction: (.+)/i,
+  /Wait[,.]? (.+)/i,
+];
+```
+
+### Trust Defense Layer (Anti-Injection)
+
+Inspired by the Windsurf SpAIware exploit. Any signal derived from agent output produced after a WebFetch or WebSearch call is flagged as potentially tainted:
+
+```typescript
+function applyTrustGate(
+  candidate: MemoryCandidate,
+  externalToolCallStep: number | undefined,
+): MemoryCandidate {
+  if (externalToolCallStep !== undefined && candidate.originatingStep > externalToolCallStep) {
+    return {
+      ...candidate,
+      needsReview: true,
+      confidence: candidate.confidence * 0.7,
+      trustFlags: { contaminated: true, contaminationSource: 'web_fetch' },
+    };
+  }
+  return candidate;
+}
+```
+
+### Performance Budget
+
+| Resource | Hard Limit | Enforcement |
+|---------|-----------|-------------|
+| CPU per event (ingest) | 2ms | `process.hrtime.bigint()` measurement; logged if exceeded, never throw |
+| CPU for finalize (non-LLM) | 100ms | Budget tracked; abort if exceeded |
+| Scratchpad resident memory | 50MB | Pre-allocated buffers; evict low-value signals on overflow |
+| LLM synthesis calls per session | 1 max | Counter enforced in `finalize()` |
+| Memories promoted per session | 20 (build), 5 (insights), 3 (others) | Hard cap |
+| DB writes per session | 1 batched transaction after finalize | No writes during execution |
+
+### Key Implementation Details (Reference V4)
+
+```typescript
+// Dead-end detection patterns (from agent text stream)
+const DEAD_END_LANGUAGE_PATTERNS = [
+  /this approach (won't|will not|cannot) work/i,
+  /I need to abandon this/i,

+
+## 5. Scratchpad to Validated Promotion Pipeline
+
+### Scratchpad Data Structures
+
+```typescript
+interface Scratchpad {
+  sessionId: string;
+  sessionType: SessionType;
+  startedAt: number;
+  signals: Map<SignalType, ObserverSignal[]>;
+  analytics: ScratchpadAnalytics;
+  acuteCandidates: AcuteCandidate[];
+}
+
+interface ScratchpadAnalytics {
+  fileAccessCounts: Map<string, number>;
+  fileFirstAccess: Map<string, number>;
+  fileLastAccess: Map<string, number>;
+  fileEditSet: Set<string>;
+  grepPatternCounts: Map<string, number>;
+  errorFingerprints: Map<string, number>;
+  currentStep: number;
+  recentToolSequence: CircularBuffer<string>;   // last 8 tool calls
+  intraSessionCoAccess: Map<string, Set<string>>;
+  configFilesTouched: Set<string>;
+  selfCorrectionCount: number;
+  totalInputTokens: number;
+}
+```
+
+### Promotion Gates by Session Type
+
+| Session Type | Gate Trigger | Max Memories | Primary Signals |
+|---|---|---|---|
+| Build (full pipeline) | QA passes | 20 | All 17 signals |
+| Insights | Session end | 5 | co_access, self_correction, repeated_grep |
+| Roadmap | Session end | 3 | decision, requirement |
+| Terminal (agent terminal) | Session end | 3 | error_retry, sequence |
+| Changelog | Skip | 0 | None |
+| Spec Creation | Spec accepted | 3 | file_access, module_insight |
+| PR Review | Review completed | 8 | error_retry, self_correction |
+
+### Promotion Filter Pipeline
+
+1. **Validation filter**: discard signals from failed approaches (unless becoming `dead_end`)
+2. **Frequency filter**: require minimum sessions per signal class
+3. **Novelty filter**: cosine similarity > 0.88 to existing memory = discard
+4. **Trust gate**: contamination check for post-external-tool signals
+5. **Scoring**: final confidence from signal priority + session count + source trust multiplier
+6. **LLM synthesis**: single `generateText()` call — raw signal data → 1-3 sentence memory content
+7. **Embedding generation**: batch embed all promoted memories
+8. **DB write**: single transaction for all promoted memories
+
+### Scratchpad Checkpointing
+
+At each subtask boundary, checkpoint the scratchpad to disk to survive Electron crashes during long pipelines:
+
+```typescript
+await scratchpadStore.checkpoint(workUnitRef, sessionId);
+// On restart: restore from checkpoint and continue
+```
+
+For builds with more than 5 subtasks, promote scratchpad notes after each validated subtask rather than waiting for the full pipeline.

+
+Layer 1: computed from code — fast, accurate, automatically maintained via file watchers.
+Layer 2: LLM analysis of Layer 1 subgraphs — async, scheduled.
+Layer 3: accumulates from agent sessions and user input — continuous, incremental.
+
+### tree-sitter WASM Integration
+
+```typescript
+import Parser from 'web-tree-sitter';
+import { app } from 'electron';
+import { join } from 'path';
+
+const GRAMMAR_PATHS: Record<string, string> = {
+  typescript:  'tree-sitter-typescript.wasm',
+  tsx:         'tree-sitter-tsx.wasm',
+  python:      'tree-sitter-python.wasm',
+  rust:        'tree-sitter-rust.wasm',
+  go:          'tree-sitter-go.wasm',
+  javascript:  'tree-sitter-javascript.wasm',
+};
+
+export class TreeSitterLoader {

+      ? join(process.resourcesPath, 'grammars')
+      : join(__dirname, '..', '..', '..', '..', 'node_modules', 'tree-sitter-wasms');
+  }
+
+  async initialize(): Promise<void> {
+    await Parser.init({ locateFile: (f) => join(this.getWasmDir(), f) });
+  }

+    if (!wasmFile) return null;
+    return Parser.Language.load(join(this.getWasmDir(), wasmFile));
+  }
+}
+```
+
+Grammar load time: ~50ms per grammar. Incremental re-parse: <5ms on edit. No native rebuild on Electron updates.
+
+### AST-Based Chunking (V5 New — Built In From Day One)
+
+Instead of chunking code by fixed line counts, split at function/class boundaries using tree-sitter. This prevents function bodies from being split across chunks.
+
+```typescript
+interface ASTChunk {
+  content: string;
+  filePath: string;
+  language: string;
+  chunkType: 'function' | 'class' | 'module' | 'prose';
+  startLine: number;
+  endLine: number;
+  name?: string;               // Function name, class name, etc.
+  contextPrefix: string;       // Prepended at embed time
+}
+
+export async function chunkFileByAST(
+  filePath: string,
+  content: string,
+  lang: string,
+  parser: Parser,
+): Promise<ASTChunk[]> {
+  const tree = parser.parse(content);
+  const chunks: ASTChunk[] = [];
+
+  // Walk tree looking for function/class declarations
+  // Split at these boundaries; never split a function body across chunks
+  // For files with no AST structure (JSON, .md), fall back to 100-line chunks
+
+  const query = CHUNK_QUERIES[lang];
+  if (!query) return fallbackChunks(content, filePath);
+
+  const matches = query.matches(tree.rootNode);
+  for (const match of matches) {
+    const node = match.captures[0].node;
+    chunks.push({
+      content: node.text,
+      filePath,
+      language: lang,
+      chunkType: nodeTypeToChunkType(node.type),
+      startLine: node.startPosition.row + 1,
+      endLine: node.endPosition.row + 1,
+      name: extractName(node),
+      contextPrefix: buildContextPrefix(filePath, node),
+    });
+  }
+
+  return chunks;
+}
+```
+
+The `contextPrefix` is critical — it's prepended at embed time for contextual embeddings (see Section 8).
+
+### Impact Analysis via Closure Table
+
+Pre-computed closure enables O(1) "what breaks if I change X?" queries:
+
+```typescript
+// Agent tool call: analyzeImpact({ target: "auth/tokens.ts:verifyJwt", maxDepth: 3 })
+// SQL:
+// SELECT descendant_id, depth, path, total_weight
+// FROM graph_closure
+// WHERE ancestor_id = ? AND depth <= 3
+// ORDER BY depth, total_weight DESC
+```
+
+### Staleness Model (Glean-Inspired)
+
+When a source file changes, immediately mark all edges from it as stale (`stale_at = NOW()`). Re-index asynchronously. Agents always query `WHERE stale_at IS NULL`.
+
+```typescript
+// IncrementalIndexer: chokidar file watcher with 500ms debounce
+// On change: markFileEdgesStale(filePath) → rebuildEdges(filePath) → updateClosure()
+```
+
+### Kuzu Migration Threshold
+
+Migrate from SQLite closure tables to Kuzu graph database when:
+- 50,000+ graph nodes, OR
+- 500MB SQLite size, OR
+- P99 graph query latency > 100ms
+
+---
+
+## 7. Complete Retrieval Pipeline
+
+V5 builds the complete pipeline from day one. No phased introduction of retrieval tiers.
+
+### Pipeline Overview
+
+```
+Stage 1: CANDIDATE GENERATION (parallel, ~10-50ms)
+├── Path A: Dense vector search via sqlite-vec
+│   └── 256-dim MRL query → top 30 (cosine similarity, fast)
+├── Path B: FTS5 BM25 keyword search
+│   └── Exact technical terms → top 20
+└── Path C: Knowledge graph traversal
+    └── Files in recently accessed module → 1-hop neighbors → top 15
+
+De-duplicate across paths.
+Total: ~50-70 candidates.
+
+Stage 2a: RRF FUSION + PHASE FILTERING (~2ms)
+└── Weighted Reciprocal Rank Fusion (identifier queries: FTS5 0.5 / graph 0.3 / dense 0.2)
+                                      (semantic queries: dense 0.5 / FTS5 0.25 / graph 0.25)
+                                      (structural queries: graph 0.6 / FTS5 0.25 / dense 0.15)
+
+Stage 2b: GRAPH NEIGHBORHOOD BOOST (~5ms) ← FREE LUNCH, UNIQUE ADVANTAGE
+└── For each top-10 result, query closure table for 1-hop neighbors
+    Boost candidates in positions 11-50 that neighbor top results:
+    boosted_score = rrf_score + 0.3 × (neighbor_count / 10)
+
+Stage 3: CROSS-ENCODER RERANKING (~85-380ms, local Electron only)
+├── Qwen3-Reranker-0.6B via Ollama
+├── Top 20 candidates → final top 8
+└── In cloud/web mode, use Cohere Rerank API (~$1/1K queries)
+
+Stage 4: CONTEXT PACKING (~1ms)
+├── Deduplicate overlapping chunks
+├── Cluster by file locality
+├── Pack into token budget per phase
+└── Append citation chip format to each memory
+```
+
+### Query Type Detection
+
+```typescript
+function detectQueryType(query: string, recentToolCalls: string[]): 'identifier' | 'semantic' | 'structural' {
+  // Identifier: query contains camelCase, snake_case, or known file paths
+  if (/[a-z][A-Z]|_[a-z]/.test(query) || query.includes('/')) return 'identifier';
+
+  // Structural: recent tool calls include analyzeImpact or graph queries
+  if (recentToolCalls.some(t => t === 'analyzeImpact' || t === 'getDependencies')) return 'structural';
+
+  return 'semantic';
+}
+```
+
+### BM25 via SQLite FTS5
+
+**Note:** FTS5 is used in ALL modes (local and cloud). Turso's Tantivy is cloud-only and inconsistent. FTS5 is simpler and identical everywhere.
+
+```sql
+-- BM25 search
+SELECT m.id, bm25(memories_fts) AS bm25_score
+FROM memories_fts
+JOIN memories m ON memories_fts.memory_id = m.id
+WHERE memories_fts MATCH ?
+  AND m.project_id = ?
+  AND m.deprecated = 0
+ORDER BY bm25_score   -- lower is better in SQLite FTS5
+LIMIT 100;
+```
+
+### Reciprocal Rank Fusion
+
+```typescript
+function weightedRRF(
+  paths: Array<{ results: Array<{ memoryId: string }>; weight: number }>,
+  k: number = 60,
+): Map<string, number> {
+  const scores = new Map<string, number>();
+
+  for (const { results, weight } of paths) {
+    results.forEach((r, rank) => {
+      const contribution = weight / (k + rank + 1);
+      scores.set(r.memoryId, (scores.get(r.memoryId) ?? 0) + contribution);
+    });
+  }
+
+  return scores;
+}
+```
+
+**IMPORTANT — libSQL FULL OUTER JOIN workaround**: libSQL doesn't support `FULL OUTER JOIN`. Use UNION pattern for RRF merging:
+
+```sql
+-- Merge dense and BM25 results without FULL OUTER JOIN
+SELECT id FROM (
+  SELECT memory_id AS id FROM dense_results
+  UNION
+  SELECT memory_id AS id FROM bm25_results
+)
+```
+
+RRF scoring is done application-side after fetching both result sets.
+
+### Graph Neighborhood Boost (The Unique Advantage)
+
+This is Auto Claude's primary competitive differentiator in retrieval. Zero competitor does this.
+
+```typescript
+async function applyGraphNeighborhoodBoost(
+  rankedCandidates: RankedMemory[],
+  topK: number = 10,
+): Promise<RankedMemory[]> {
+  // Step 1: Get the file paths of the top-K results
+  const topFiles = rankedCandidates.slice(0, topK).flatMap(m => m.relatedFiles);
+
+  // Step 2: Query closure table for 1-hop neighbors of those files
+  const neighborNodeIds = await db.execute(`
+    SELECT DISTINCT gc.descendant_id
+    FROM graph_closure gc
+    JOIN graph_nodes gn ON gc.ancestor_id = gn.id
+    WHERE gn.file_path IN (${topFiles.map(() => '?').join(',')})
+      AND gc.depth = 1
+  `, topFiles);
+
+  const neighborFileIds = new Set(neighborNodeIds.rows.map(r => r.descendant_id as string));
+
+  // Step 3: Boost candidates in positions 11-50 that share files with neighbors
+  return rankedCandidates.map((candidate, rank) => {
+    if (rank < topK) return candidate;
+
+    const neighborCount = candidate.relatedFiles.filter(f =>
+      neighborFileIds.has(f)
+    ).length;
+
+    if (neighborCount === 0) return candidate;
+
+    return {
+      ...candidate,
+      score: candidate.score + 0.3 * (neighborCount / Math.max(topFiles.length, 1)),
+      boostReason: 'graph_neighborhood',
+    };
+  }).sort((a, b) => b.score - a.score);
+}
+```
+
+Expected improvement: +7 percentage points on retrieval quality with ~5ms additional latency.
+
+### Phase-Aware Scoring
+
+```typescript
+const PHASE_WEIGHTS: Record<UniversalPhase, Partial<Record<MemoryType, number>>> = {
+  define: {

+  },
+  explore: {

+  },
+};

+function computeFinalScore(memory: Memory, queryEmbedding: number[], phase: UniversalPhase): number {
+  const cosine = cosineSimilarity(memory.embedding, queryEmbedding);

+  const trustWeight = SOURCE_TRUST_MULTIPLIERS[memory.source];
+
+  return base * phaseWeight * trustWeight * memory.confidence;
+}
+```
+
+### Context Packing (Token Budgets per Phase)
+
+```typescript
+const DEFAULT_PACKING_CONFIG: Record<UniversalPhase, ContextPackingConfig> = {
+  define:    { totalBudget: 2500, allocation: { workflow_recipe: 0.30, requirement: 0.20, decision: 0.20, dead_end: 0.15, task_calibration: 0.10, other: 0.05 } },
+  implement: { totalBudget: 3000, allocation: { gotcha: 0.30, error_pattern: 0.25, causal_dependency: 0.15, pattern: 0.15, dead_end: 0.10, other: 0.05 } },
+  validate:  { totalBudget: 2500, allocation: { error_pattern: 0.30, requirement: 0.25, e2e_observation: 0.25, work_unit_outcome: 0.15, other: 0.05 } },
+  refine:    { totalBudget: 2000, allocation: { error_pattern: 0.35, gotcha: 0.25, dead_end: 0.20, pattern: 0.15, other: 0.05 } },

+  reflect:   { totalBudget: 1500, allocation: { work_unit_outcome: 0.40, task_calibration: 0.35, dead_end: 0.15, other: 0.10 } },
+};
+```
+
+### HyDE Fallback
+
+When fewer than 3 results score above 0.5 after all pipeline stages, generate a hypothetical ideal memory and use that for a secondary dense search:
+
+```typescript
+// Applied only for search_memory tool calls (T3), never for proactive injection
+if (topResults.filter(r => r.score > 0.5).length < 3) {
+  const hypoMemory = await generateText({
+    model: fastModel,
+    prompt: `Write a 2-sentence memory that would perfectly answer: "${query}"`,
+    maxTokens: 100,
+  });
+  return denseSearch(embed(hypoMemory.text), filters);
+}
+```
+
+### File Staleness Detection (4 Layers)
+
+```
+1. `memory.staleAt` explicitly set (manual deprecation or file deletion)
+2. `memory.lastAccessedAt` older than `memory.decayHalfLifeDays` — confidence penalty applied
+3. `relatedFiles` changed in git log since `memory.commitSha` — confidence reduced proportionally
+4. File modification time newer than `memory.createdAt` by more than 30 days — trigger review flag
+```
+
+---
+
+## 8. Embedding Strategy
+
+### V5 Changes From V4
+
+1. **OpenAI replaces Voyage** as API fallback — `text-embedding-3-small` at 1024-dim
+2. **Contextual embeddings built in from day one** — prepend file/module context before every embed
+3. **1024-dim everywhere** — OpenAI requests 1024-dim to match Qwen3 storage format
+
+### Three-Tier Fallback
+
+| Priority | Model | When Available | Dims | Notes |
+|---|---|---|---|---|
+| 1 | `qwen3-embedding:8b` via Ollama | >32GB RAM available | 1024 (MRL) | SOTA local, auto-selected by RAM check |
+| 2 | `qwen3-embedding:4b` via Ollama | Ollama running (recommended) | 1024 (MRL) | Default recommendation |
+| 3 | `qwen3-embedding:0.6b` via Ollama | Low-memory machines | 1024 | For Stage 1 candidate generation |
+| 4 | OpenAI `text-embedding-3-small` | API key configured | 1024 | Request `dimensions: 1024` explicitly |
+| 5 | ONNX bundled `bge-small-en-v1.5` | Always | 384 | Zero-config fallback, ~100MB |
+
+**Dimension consistency note**: OpenAI `text-embedding-3-small` natively produces 1536-dim but supports truncation. Always request `dimensions: 1024` to match Qwen3 storage. Track `model_id` per embedding to prevent cross-model similarity comparisons.
+
+```typescript
+// OpenAI embedding with dimension matching
+const response = await openai.embeddings.create({
+  model: 'text-embedding-3-small',
+  input: text,
+  dimensions: 1024,   // Match Qwen3's MRL dimension
+});
+```
+
+### Contextual Embeddings (V5 New — Built In From Day One)
+
+Before embedding any memory, prepend its file/module context. This is Anthropic's contextual embedding technique adapted for code.
+
+```typescript
+function buildContextualText(chunk: ASTChunk): string {
+  const prefix = [
+    `File: ${chunk.filePath}`,
+    chunk.chunkType !== 'module' ? `${chunk.chunkType}: ${chunk.name ?? 'unknown'}` : null,
+    `Lines: ${chunk.startLine}-${chunk.endLine}`,
+  ].filter(Boolean).join(' | ');
+
+  return `${prefix}\n\n${chunk.content}`;
+}
+
+// For memories (not just code chunks):
+function buildMemoryContextualText(memory: Memory): string {
+  const parts = [
+    memory.relatedFiles.length > 0 ? `Files: ${memory.relatedFiles.join(', ')}` : null,
+    memory.relatedModules.length > 0 ? `Module: ${memory.relatedModules[0]}` : null,
+    `Type: ${memory.type}`,
+  ].filter(Boolean).join(' | ');
+
+  return parts ? `${parts}\n\n${memory.content}` : memory.content;
+}
+
+async function embedMemory(memory: Memory, embeddingService: EmbeddingService): Promise<number[]> {
+  const contextualText = buildMemoryContextualText(memory);
+  return embeddingService.embed(contextualText);
+}
+```
+
+### Matryoshka Dimension Strategy
+
+Both Qwen3-embedding models support MRL. Use tiered dimensions:
+
+- **Stage 1 candidate generation**: 256-dim — 14x faster, ~90% accuracy retained
+- **Stage 3 precision reranking**: 1024-dim — full quality
+- **Storage**: 1024-dim stored permanently per memory record
+
+### Embedding Cache
+
+```typescript
+class EmbeddingCache {
+  async get(text: string, modelId: string, dims: number): Promise<number[] | null> {
+    const key = sha256(`${text}:${modelId}:${dims}`);
+    const row = await db.execute(
+      'SELECT embedding FROM embedding_cache WHERE key = ? AND expires_at > ?',
+      [key, Date.now()]
+    );
+    return row.rows[0] ? deserializeEmbedding(row.rows[0].embedding as ArrayBuffer) : null;
+  }
+
+  async set(text: string, modelId: string, dims: number, embedding: number[]): Promise<void> {
+    const key = sha256(`${text}:${modelId}:${dims}`);
+    await db.execute(
+      'INSERT OR REPLACE INTO embedding_cache (key, embedding, model_id, dims, expires_at) VALUES (?,?,?,?,?)',
+      [key, serializeEmbedding(embedding), modelId, dims, Date.now() + 7 * 86400 * 1000]
+    );
+  }
+}
+```
+

+
+## 9. Agent Loop Integration
+
+### Three-Tier Injection Points
+
+```
+INJECTION POINT 1: System prompt (before streamText())
+   Content: global memories, module memories, workflow recipes
+   Latency budget: up to 500ms
+
+INJECTION POINT 2: Initial user message (before streamText())
+   Content: prefetched file contents, work state (if resuming)
+   Latency budget: up to 2s
+
+INJECTION POINT 3: Tool result augmentation (during streamText())
+   Content: gotchas, dead_ends for file just read
+   Latency budget: < 100ms per augmentation
+   Mechanism: tool execute() appends to result string
+
+INJECTION POINT 4: prepareStep callback (between each step)
+   Content: step-specific memory based on current agent state
+   Latency budget: < 50ms
+   Mechanism: prepareStep returns updated messages array
+```
+
+### prepareStep Active Injection

+
+### Planner: Memory-Guided Planning
+
+```typescript

+  ]);
+
+  return formatPlannerSections({ calibrations, deadEnds, causalDeps, outcomes, recipes });
+}
+```
+
+Planning transformations:
+1. **Calibration** → multiply subtask count estimates by empirical ratio
+2. **Dead ends** → write constraints directly into the plan
+3. **Causal deps** → expand scope to include coupled files pre-emptively
+
+### Coder: Predictive Pre-Loading
+
+Budget: max 32K tokens (~25% of context), max 12 files. Files accessed in >80% of past sessions load first; >50% load second.
+
+### QA: Targeted Validation
+
+QA sessions start with `e2e_observation`, `error_pattern`, and `requirement` memories injected before the first MCP call.
+
+### E2E Validation Memory Pipeline

+
+**Note on libSQL in worker threads**: `@libsql/client` uses HTTP for cloud mode and is inherently async-safe. For local mode, the client is pure JS — safe in worker_threads. All writes are proxied through main thread MemoryService to avoid WAL conflicts.
+
+### IPC Message Types
+
+```typescript
+export type MemoryIpcRequest =
+  | { type: 'memory:search'; requestId: string; query: string; filters: MemorySearchFilters }
+  | { type: 'memory:record'; requestId: string; entry: MemoryRecordEntry }
+  | { type: 'memory:tool-call'; toolName: string; args: Record<string, unknown>; stepIndex: number }
+  | { type: 'memory:tool-result'; toolName: string; result: string; isError: boolean; stepIndex: number }
+  | { type: 'memory:reasoning'; text: string; stepIndex: number }
+  | { type: 'memory:step-complete'; stepNumber: number }
+  | { type: 'memory:session-complete'; outcome: SessionOutcome; stepsExecuted: number };
+```
+
+All IPC uses async request-response with UUID correlation. 3-second timeout: on timeout, agent proceeds without memory context (graceful degradation).
+
+### Parallel Subagent Scratchpad Merger
+
+```typescript
+export class ParallelScratchpadMerger {
+  merge(scratchpads: ScratchpadStore[]): MergedScratchpad {
+    const allEntries = scratchpads.flatMap((s, idx) =>
+      s.getAll().map(e => ({ ...e, sourceAgentIndex: idx }))
+    );
+
+    const deduplicated = this.deduplicateByContent(allEntries);
+
+    // Quorum boost: entries observed by 2+ agents get confidence boost
+    return {
+      entries: deduplicated.map(entry => ({
+        ...entry,
+        quorumCount: allEntries.filter(e =>
+          e.sourceAgentIndex !== entry.sourceAgentIndex &&
+          this.contentSimilarity(e.content, entry.content) > 0.85
+        ).length + 1,
+        effectiveFrequencyThreshold: entry.confirmedBy >= 1 ? 1 : DEFAULT_FREQUENCY_THRESHOLD,
+      })),
+    };
+  }
+}
+```

+
+## 12. Cross-Session Pattern Synthesis
+
+### Three Synthesis Modes
+
+**Mode 1: Incremental (after every session, no LLM)** — Update rolling file statistics, co-access edge weights, error fingerprint registry. O(n) over new session's signals.
+
+**Mode 2: Threshold-triggered (sessions 5, 10, 20, 50, 100 — one LLM call per trigger per module)** — Synthesize cross-session patterns. Output: 0-5 novel memories per call.
+
+**Mode 3: Scheduled (weekly — one LLM call per cross-module cluster)** — Find module pairs with high co-access not yet captured as `causal_dependency`.
+
+### Threshold Synthesis
+
+```typescript
+const SYNTHESIS_THRESHOLDS = [5, 10, 20, 50, 100];
+
+async function triggerModuleSynthesis(module: string, sessionCount: number): Promise<void> {
+  const stats = buildModuleStatsSummary(module);
+
+  const synthesis = await generateText({
+    model: fastModel,
+    prompt: `You are analyzing ${sessionCount} agent sessions on the "${module}" module.
+
+File access patterns:
+${stats.topFiles.map(f => `- ${f.path}: ${f.sessions} sessions`).join('\n')}
+
+Co-accessed pairs:
+${stats.strongCoAccess.map(e => `- ${e.fileA} + ${e.fileB}: ${e.sessions} sessions`).join('\n')}
+
+Recurring errors:
+${stats.errors.map(e => `- "${e.errorType}": ${e.sessions} sessions, resolved: ${e.resolvedHow}`).join('\n')}
+
+Identify (max 5 memories, omit obvious things):
+1. Files to prefetch (prefetch_pattern)
+2. Non-obvious file coupling (causal_dependency or gotcha)
+3. Recurring errors (error_pattern)
+4. Non-obvious module purpose (module_insight)
+
+Format: JSON [{ "type": "...", "content": "...", "relatedFiles": [...], "confidence": 0.0-1.0 }]`,
+    maxTokens: 400,
+  });
+
+  const memories = parseSynthesisOutput(synthesis.text);
+  for (const memory of memories) {
+    if (await isNovel(memory)) {
+      await memoryService.store({ ...memory, source: 'observer_inferred', needsReview: true });
+    }
+  }
+}
+```

+## 13. UX and Developer Trust
+
+### Memory Panel Navigation
+
+```
+Memory (Cmd+Shift+M)
+├── Health Dashboard (default)
+│   ├── Stats: total | active (used 30d) | needs-review | tokens-saved-this-session
+│   ├── Health score 0-100
+│   ├── Module coverage progress bars
+│   └── Needs Attention: stale memories, pending reviews
+├── Module Map (collapsible per-module cards)
+├── Memory Browser (search + filters, full provenance)
+├── Ask Memory (chat with citations)
+└── [Cloud only] Team Memory
+```
+
+### Citation Chips
+
+Memory citation format in agent output: `[^ Memory: JWT 24h expiry decision]`
+
+The renderer detects `[Memory #ID: brief text]` and replaces with `MemoryCitationChip` — amber-tinted pill with a flag button. Dead-end citations use red tint. More than 5 citations collapse to "Used N memories [view all]".
+
+### Session-End Summary
+
+```
+Session Complete: Auth Bug Fix
+Memory saved ~6,200 tokens of discovery this session
+
+What the agent remembered:
+  - JWT decision → used when planning approach  [ok]
+  - Redis gotcha → avoided concurrent validation bug  [ok]
+
+What the agent learned (4 new memories):
+  1/4  GOTCHA  middleware/auth.ts  [ok] [edit] [x]
+       Token refresh fails silently when Redis is unreachable
+  2/4  ERROR PATTERN  tests/auth/  [ok] [edit] [x]
+       Auth tests require REDIS_URL env var — hang without it
+  ...
+
+[Save all confirmed]    [Review later]
+```
+
+### Trust Progression System
+
+**Level 1 — Cautious (Sessions 1-3):** inject confidence > 0.80 only; all new memories require confirmation; advance: 3 sessions + 50% confirmed.
+
+**Level 2 — Standard (Sessions 4-15):** inject confidence > 0.65; "Confirm all" is default; advance: 10+ sessions, <5% correction rate.
+
+**Level 3 — Confident (Sessions 16+):** inject confidence > 0.55; session summary condensed to `needsReview` only.
+
+**Level 4 — Autonomous (Opt-in only):** inject confidence > 0.45; session summary suppressed by default.
+
+Trust regression: if user flags 3+ memories wrong in one session, offer (not force) moving to more conservative level.
+
+### Teach the AI Entry Points
+
+| Method | Location | Action |
+|---|---|---|
+| `/remember [text]` | Agent terminal | Creates `user_taught` memory immediately |
+| `Cmd+Shift+M` | Global | Opens Teach panel |
+| Right-click file | File tree | Opens Teach panel pre-filled with file path |
+| Import CLAUDE.md / .cursorrules | Settings | Parse rules into typed memories |
+
+---
+
+## 14. Cloud Sync, Multi-Device, and Web App
+
+### The Login-Gated Architecture
+
+The Electron app is open source and free. Cloud features are gated behind Convex Better Auth login:
+
+```
+Electron App (all users)
+├── Free tier: libSQL in-process → memory.db (offline, full features)
+└── Logged-in tier: libSQL embedded replica + Turso Cloud sync
+    ├── Same SQL queries, same tables
+    ├── Reads from local replica (fast, offline-tolerant)
+    ├── Syncs to Turso Cloud every 60s
+    └── Convex for: auth state, team features, billing UI, real-time memory panel
+
+Web App (Next.js SaaS, same repo/OSS)
+├── Self-hosted: users run their own stack (no cloud features)
+└── Cloud hosted (auto-claude.app): Turso Cloud + Convex
+    ├── Pure cloud libSQL (no local file)
+    ├── OpenAI embeddings (no Ollama)
+    └── Cohere Rerank API
+```
+
+### Cloud Sync Flow
+
+```
+Electron write → libSQL local (immediate)
+             → Turso embedded replica sync (within 60s)
+
+Other device read → Turso Cloud fetch → embedded replica
+
+Conflict (same memory edited on two devices before sync):
+├── Non-conflicting fields (access_count, tags): auto-merge
+└── Content field: present both versions, require user decision
+```
+
+### Web App Architecture Differences
+
+| Feature | Electron (local) | Web App (cloud) |
+|---------|-----------------|-----------------|
+| Database | libSQL in-process file | libSQL → Turso Cloud |
+| Embeddings | Qwen3 via Ollama | OpenAI text-embedding-3-small |
+| Reranking | Qwen3-Reranker-0.6B via Ollama | Cohere Rerank API |
+| Graph indexing | tree-sitter WASM | tree-sitter WASM (in Node.js worker) |
+| Auth | Convex Better Auth | Convex Better Auth |
+| Agent execution | Worker threads | Next.js API routes + queue |
+
+The same retrieval SQL queries work in both modes. Only the client connection differs.
+
+### Database-Per-Tenant (Turso)
+
+```typescript
+// Create a dedicated Turso database per user+project
+async function getOrCreateProjectDb(
+  userId: string,
+  projectId: string,
+  convexToken: string,
+): Promise<Client> {
+  const dbName = `user-${userId}-proj-${projectId}`;
+  const tursoClient = createTursoClient(tursoApiToken);
+
+  const existing = await tursoClient.databases.get(dbName);
+  if (!existing) {
+    await tursoClient.databases.create({ name: dbName, group: 'memory' });
+  }
+
+  const dbToken = await tursoClient.databases.createToken(dbName);
+
+  return createClient({
+    url: `libsql://${dbName}.turso.io`,
+    authToken: dbToken.jwt,
+  });
+}
+```
+
+---
+
+## 15. Team and Organization Memories
+
+### Four Scope Levels
+
+| Scope | Visible To | Use Cases |
+|---|---|---|
+| Personal | Only you | Workflow preferences, personal aliases |
+| Project | All project members | Gotchas, error patterns, decisions |
+| Team | All team members | Organization conventions, architecture |
+| Organization | All org members | Security policies, compliance requirements |
+
+### Team Onboarding
+
+When a new developer joins, surface the 5 most important team memories immediately. Sort by `confidence × pinned_weight × access_count`. New developer sees months of accumulated tribal knowledge in 60 seconds.
+
+### Team Memory Dispute Resolution
+
+1. Team member clicks "Dispute"
+2. Threaded comment opens on the memory
+3. Steward notified
+4. Memory gets "disputed" badge — agents still use it but with `confidence × 0.8`
+5. Resolution: steward updates or team admin escalates
+
+---
+
+## 16. Privacy and Compliance
+
+### What Stays Local by Default
+
+- Personal-scope memories
+- Any memory flagged by the secret scanner
+- Embedding vectors when "vectors-only" mode selected
+
+### Secret Scanner
+
+Runs before any cloud upload and before storing `user_taught` memories:
+
+```typescript
+const SECRET_PATTERNS = [
+  /sk-[a-zA-Z0-9]{48}/,
+  /sk-ant-[a-zA-Z0-9-]{95}/,
+  /ghp_[a-zA-Z0-9]{36}/,
+  /-----BEGIN (RSA|EC) PRIVATE KEY-----/,
+  /password\s*[:=]\s*["']?\S+/i,
+];
+```
+
+### GDPR Controls
+
+- Export all memories as JSON (machine-readable)
+- Export as Markdown (human-readable, importable)
+- Export as CLAUDE.md format (portable)
+- Delete all memories (hard delete for explicit account deletion)
+- Request data archive (SQLite + embeddings)
+
+---
+
+## 17. Database Schema
+
+The V5 schema uses `@libsql/client` compatible SQL. No `better-sqlite3`. All queries are async.
+
+```sql

+PRAGMA synchronous = NORMAL;
+PRAGMA foreign_keys = ON;

+      AND user_verified = 0
+      AND (julianday(?) - julianday(deprecated_at)) > 30
+  `, [projectId, now]);
+
+  // Evict expired embedding cache
+  await db.execute('DELETE FROM embedding_cache WHERE expires_at < ?', [Date.now()]);
+}
+```
+
+### Access Count as Trust Signal
+
+Every time a memory is injected, increment `access_count`. After 5 accesses with no correction, auto-increment `confidence` by 0.05 (capped at 0.95). After 10 accesses, remove `needsReview` flag.
+
+---
+
+## 19. A/B Testing and Metrics
+
+### Control Group Design
+
+5% of new sessions assigned to control group (no memory injection). Control sessions still generate observer signals — they just receive no injections.
+
+```typescript
+enum MemoryABGroup {
+  CONTROL = 'control',         // No injection (5%)
+  PASSIVE_ONLY = 'passive',    // T1 + T2 only (10%)
+  FULL = 'full',               // All 4 tiers (85%)
+}
+
+function assignABGroup(sessionId: string, projectId: string): MemoryABGroup {
+  const hash = murmurhash(`${sessionId}:${projectId}`) % 100;
+  if (hash < 5)  return MemoryABGroup.CONTROL;
+  if (hash < 15) return MemoryABGroup.PASSIVE_ONLY;
+  return MemoryABGroup.FULL;
+}
+```
+
+### Key Metrics
+
+| Metric | Definition | Target |
+|---|---|---|
+| Tool calls per task | Total tool calls in session | <20% reduction vs control |
+| File re-reads | Read calls on files previously read in prior session | <50% reduction vs control |
+| QA first-pass rate | QA passes without fix cycle | >15% improvement vs control |
+| Dead-end re-entry rate | Agent tries a previously-failed approach | <5% |
+| User correction rate | Memories flagged / memories used | <5% |
+| Graph boost rate | Fraction of retrievals where neighborhood boost changed top-8 | Track for value validation |
+
+### Phase Weight Learning
+
+After 30+ sessions, run background weight optimization: which memory types most strongly correlate with QA first-pass success per phase? Human review required before applying new weights.
+
+---
+
+## 20. Implementation Checklist
+
+V5 is built complete, not phased. The retrieval pipeline, AST chunking, contextual embeddings, and graph neighborhood boost are all implemented from the start. Implementation order follows dependency order.
+
+### Step 1: libSQL Foundation (1-2 days)
+
+```bash
+cd apps/desktop
+npm install @libsql/client
+# Remove better-sqlite3 if present for memory module (keep for other uses if needed)
+```
+
+Create `apps/desktop/src/main/ai/memory/db.ts`:
+
+```typescript
+import { createClient, type Client } from '@libsql/client';
+import { app } from 'electron';
+import { join } from 'path';
+import { MEMORY_SCHEMA_SQL } from './schema';
+
+let _client: Client | null = null;
+
+export async function getMemoryClient(
+  tursoSyncUrl?: string,
+  authToken?: string,
+): Promise<Client> {
+  if (_client) return _client;
+
+  const localPath = join(app.getPath('userData'), 'memory.db');
+
+  _client = createClient({
+    url: `file:${localPath}`,
+    ...(tursoSyncUrl && authToken ? { syncUrl: tursoSyncUrl, authToken, syncInterval: 60 } : {}),
+  });
+
+  // Initialize schema (idempotent)
+  await _client.executeMultiple(MEMORY_SCHEMA_SQL);
+
+  // Load sqlite-vec extension for local mode only
+  // Cloud Turso has built-in vector support (DiskANN) — no extension needed
+  if (!tursoSyncUrl) {
+    const vecExtPath = app.isPackaged
+      ? join(process.resourcesPath, 'extensions', 'vec0')
+      : join(__dirname, '..', '..', 'node_modules', 'sqlite-vec', 'vec0');
+    await _client.execute(`SELECT load_extension('${vecExtPath}')`);
+  }
+
+  return _client;
+}
+
+export async function closeMemoryClient(): Promise<void> {
+  if (_client) {
+    await _client.close();
+    _client = null;
+  }
+}
+```
+
+**sqlite-vec with libSQL**: Use `@libsql/client` with the `vec0` extension. For cloud Turso databases, vector functions are built in. For local, bundle the vec0 extension binary.
+
+### Step 2: MemoryService Core (2-3 days)
+
+Implement `MemoryService` with:
+- `store(entry)` → inserts memory, generates contextual embedding, updates FTS5 trigger
+- `search(query, filters)` → full 4-stage pipeline (candidates → RRF → neighborhood boost → pack)
+- `searchByPattern(pattern)` → BM25-only for quick pattern matching in StepInjectionDecider
+- `insertUserTaught(content, projectId, tags)` → immediate insert for `/remember` command
+
+### Step 3: EmbeddingService (1-2 days)
+
+Implement with provider auto-detection:
+
+```typescript
+export class EmbeddingService {
+  private provider: 'ollama-8b' | 'ollama-4b' | 'ollama-0.6b' | 'openai' | 'onnx' = 'onnx';
+
+  async initialize(): Promise<void> {
+    // Check Ollama availability and RAM
+    const ollamaAvailable = await checkOllama();
+    if (ollamaAvailable) {
+      const ram = await getAvailableRAM();
+      this.provider = ram > 32 ? 'ollama-8b' : 'ollama-4b';
+    } else if (process.env.OPENAI_API_KEY) {
+      this.provider = 'openai';
+    }
+    // else: onnx bundled fallback
+  }
+
+  async embed(text: string, dims: 256 | 1024 = 1024): Promise<number[]> {
+    const cached = await this.cache.get(text, this.provider, dims);
+    if (cached) return cached;
+
+    const embedding = await this.callProvider(text, dims);
+    await this.cache.set(text, this.provider, dims, embedding);
+    return embedding;
+  }
+
+  private async callProvider(text: string, dims: number): Promise<number[]> {
+    switch (this.provider) {
+      case 'openai':
+        const res = await openai.embeddings.create({
+          model: 'text-embedding-3-small',
+          input: text,
+          dimensions: dims,   // Always 1024 for storage
+        });
+        return res.data[0].embedding;
+      // ... ollama and onnx implementations
+    }
+  }
+}
+```
+
+### Step 4: Knowledge Graph Layer 1 (5-7 days)
+
+- `TreeSitterLoader` with TypeScript + JavaScript + Python + Rust
+- `TreeSitterExtractor`: import edges, function definitions, call edges, class hierarchy
+- `ASTChunker`: split files at function/class boundaries
+- `GraphDatabase`: node/edge CRUD with closure table maintenance
+- `IncrementalIndexer`: chokidar file watcher, 500ms debounce, Glean staleness model
+
+### Step 5: Complete Retrieval Pipeline (3-4 days)
+
+- FTS5 BM25 path
+- Dense vector path (256-dim candidates, 1024-dim precision)
+- Graph traversal path (co-access edges + closure table neighbors)
+- Weighted RRF fusion (with UNION workaround — no FULL OUTER JOIN)
+- Graph neighborhood boost (the unique advantage)
+- Phase-aware scoring and context packing
+- Reranking via Qwen3-Reranker-0.6B (Ollama, local only)
+- HyDE fallback
+
+### Step 6: Memory Observer + Scratchpad (3-5 days)
+
+- `MemoryObserver` on main thread tapping WorkerBridge events
+- `Scratchpad` with O(1) analytics data structures
+- Top-5 signals: self_correction, co_access, error_retry, parallel_conflict, read_abandon
+- Trust defense layer (SpAIware protection)
+- Session-type-aware promotion gates
+- `observer.finalize()` with LLM synthesis call
+
+### Step 7: Active Injection + Agent Loop (3-4 days)
+
+- `StepInjectionDecider` (3 triggers)
+- `prepareStep` callback in `runAgentSession()`
+- Planner memory context builder
+- Prefetch plan builder (T2 pre-loading)
+- E2E observation pipeline for MCP tool results
+- Memory-aware `stopWhen` (calibration-adjusted max steps)
+
+### Step 8: Memory Panel UX (5-7 days)
+
+- Health Dashboard + Module Map + Memory Browser
+- Session-end summary panel
+- `MemoryCitationChip` in agent terminal
+- Correction modal
+- Teach panel with all entry points
+- Trust progression system (4 levels, per-project)
+- First-run experience
+- i18n keys in en.json and fr.json
+
+### Step 9: Cloud Sync + Team Features (7-10 days)
+
+- Turso Cloud integration (per-tenant database provisioning)
+- Convex integration (auth token → Turso sync URL)
+- Login-gated feature detection in Electron
+- Team memory scoping (project/team/org)
+- Dispute resolution UI
+- Secret scanner
+- GDPR export/delete controls
+
+### Step 10: Cross-Session Synthesis + A/B Testing (5-7 days)
+
+- Incremental synthesis (Mode 1, every session)
+- Threshold-triggered synthesis (Mode 2, LLM calls)
+- Weekly scheduled synthesis (Mode 3)
+- A/B group assignment and metric tracking
+- Phase weight optimization framework
+
+---
+
+## 21. Open Questions
+
+1. **sqlite-vec with @libsql/client**: The `sqlite-vec` extension works with `better-sqlite3`. With `@libsql/client`, the extension loading mechanism differs. Turso Cloud has built-in vector support (`vector_distance_cos()`). Local libSQL may need `libsql-vector` package or bundled vec0 binary. Verify before Step 1.
+
+2. **Embedding model cross-compatibility**: Memories embedded with Qwen3-4b have the same 1024-dim format as memories embedded with OpenAI text-embedding-3-small. However, embeddings from different models are NOT directly comparable (different embedding spaces). When a user switches from Ollama to OpenAI fallback or vice versa, existing memories need re-embedding. Background re-embedding job needed; track `embedding_model_id` per memory.
+
+3. **Web app agent execution**: In Next.js, agents cannot run in `worker_threads` the same way as Electron. Server-side agent execution needs a job queue (BullMQ, Inngest, or Trigger.dev). The memory system architecture is the same, but the IPC mechanism differs. Define the web app execution model before Step 9.
+
+4. **Scratchpad granularity for large pipelines**: For a 40-subtask build, promote after each validated subtask, not just at pipeline end. The exact promotion gate per subtask: does it require subtask-level QA, or is the subtask returning success sufficient? Recommendation: subtask returning success is sufficient gate; pipeline-level QA is the gate for high-confidence observer-inferred memories.
+
+5. **Tree-sitter vs. ts-morph for TypeScript**: tree-sitter extracts syntactic call sites but cannot resolve cross-module which function is being called. ts-morph has full TypeScript compiler resolution but is much slower. Use tree-sitter for Phases 1-5 (speed), add SCIP integration for precision in later phases. Mark edges with `source: 'ast'` vs `source: 'scip'`.
+
+6. **Reranking in cloud/web mode**: Qwen3-Reranker-0.6B is not available without Ollama. In cloud/web mode, Cohere Rerank API (~$1/1K queries) is used from the start as the cross-encoder reranking tier. Monitor Cohere costs and evaluate alternatives (e.g., self-hosted reranker on VPS) if costs become significant at scale.
+
+7. **Graph neighborhood boost in cloud mode**: The boost queries the `graph_closure` table which lives in libSQL/Turso. This works in all modes (local and cloud) with the same SQL. Confirm there's no cold-start state where graph_closure is empty but memories exist — if so, fall back gracefully to 2-path retrieval.
+
+8. **Turso rate limits**: The Scaler plan allows 500 databases. With database-per-tenant, this limits to 500 active project databases before upgrading to Enterprise. Plan the upgrade path before hitting this ceiling.
+
+9. **Cold-start graph indexing UX**: First project open triggers tree-sitter cold-start (30 seconds to 20 minutes). Agents should start with `source: "ast"` edges unavailable and progressively get better impact analysis. Prepend `[Knowledge Graph: indexing in progress — impact analysis may be incomplete]` to the first 3 agent sessions after project open.
+
+10. **Personal memory vs. team memory conflict**: If a team decision says "use PostgreSQL" and a developer's personal memory says "this client project uses SQLite," personal memories override project memories in retrieval scoring when the personal memory has higher confidence and is more recent. Never silently suppress team memories — surface both with attribution.

-from workspace import setup_workspace
-```
-
-### Adding Features
-
-1. Create module in appropriate folder
-2. Export API in `__init__.py`
-3. Add facade module at root if commonly imported

-# Agents Module
-
-Modular agent system for autonomous coding. This module refactors the original monolithic `agent.py` (1,446 lines) into focused, maintainable modules.
-
-## Architecture
-
-The agent system is now organized by concern:
-
-```
-auto-claude/agents/
-├── __init__.py          # Public API exports
-├── base.py              # Shared constants and imports
-├── utils.py             # Git operations and plan management
-├── memory.py            # Memory management (Graphiti + file-based)
-├── session.py           # Agent session execution
-├── planner.py           # Follow-up planner logic
-└── coder.py             # Main autonomous agent loop
-```
-
-## Modules
-
-### `base.py` (352 bytes)
-- Shared constants (`AUTO_CONTINUE_DELAY_SECONDS`, `HUMAN_INTERVENTION_FILE`)
-- Common imports and logging setup
-
-### `utils.py` (3.6 KB)
-- Git operations: `get_latest_commit()`, `get_commit_count()`
-- Plan management: `load_implementation_plan()`, `find_subtask_in_plan()`, `find_phase_for_subtask()`
-- Workspace sync: `sync_spec_to_source()`
-
-### `memory.py` (13 KB)
-- Dual-layer memory system (Graphiti primary, file-based fallback)
-- `debug_memory_system_status()` - Memory system diagnostics
-- `get_graphiti_context()` - Retrieve relevant context for subtasks
-- `save_session_memory()` - Save session insights to memory
-- `save_session_to_graphiti()` - Backwards compatibility wrapper
-
-### `session.py` (17 KB)
-- `run_agent_session()` - Execute a single agent session
-- `post_session_processing()` - Process results and update memory
-- Session logging and tool tracking
-- Recovery manager integration
-
-### `planner.py` (5.4 KB)
-- `run_followup_planner()` - Add new subtasks to completed specs
-- Follow-up planning workflow
-- Plan validation and status updates
-
-### `coder.py` (16 KB)
-- `run_autonomous_agent()` - Main autonomous agent loop
-- Planning and coding phase management
-- Linear integration
-- Recovery and stuck subtask handling
-
-## Public API
-
-The `agents` module exports a clean public API:
-
-```python
-from agents import (
-    # Main functions
-    run_autonomous_agent,
-    run_followup_planner,
-
-    # Memory functions
-    save_session_memory,
-    get_graphiti_context,
-
-    # Session management
-    run_agent_session,
-    post_session_processing,
-
-    # Utilities
-    get_latest_commit,
-    load_implementation_plan,
-    sync_spec_to_source,
-)
-```
-
-## Backwards Compatibility
-
-The original `agent.py` is now a facade that re-exports everything from the `agents` module:
-
-```python
-# Old code still works
-from agent import run_autonomous_agent, save_session_memory
-
-# New code can use modular imports
-from agents.coder import run_autonomous_agent
-from agents.memory import save_session_memory
-```
-
-All existing imports continue to work without changes.
-
-## Benefits
-
-1. **Separation of Concerns**: Each module has a clear, focused responsibility
-2. **Maintainability**: Easier to understand and modify individual components
-3. **Testability**: Modules can be tested in isolation
-4. **Backwards Compatible**: No breaking changes to existing code
-5. **Scalability**: Easy to add new agent types or features
-
-## Module Dependencies
-
-```
-coder.py
-  ├── session.py (run_agent_session, post_session_processing)
-  ├── memory.py (get_graphiti_context, debug_memory_system_status)
-  └── utils.py (git operations, plan management)
-
-session.py
-  ├── memory.py (save_session_memory)
-  └── utils.py (git operations, plan management)
-
-planner.py
-  └── session.py (run_agent_session)
-
-memory.py
-  └── base.py (constants, logging)
-```
-
-## Testing
-
-Run the verification script to test the refactoring:
-
-```bash
-python3 auto-claude/agents/test_refactoring.py
-```
-
-This verifies:
-- Module structure is correct
-- All imports work
-- Public API is accessible
-- Backwards compatibility is maintained
-
-## Migration Guide
-
-No migration needed! The refactoring maintains 100% backwards compatibility.
-
-### For new code:
-```python
-# Use focused imports for clarity
-from agents.coder import run_autonomous_agent
-from agents.memory import save_session_memory, get_graphiti_context
-from agents.session import run_agent_session
-```
-
-### For existing code:
-```python
-# Old imports continue to work
-from agent import run_autonomous_agent, save_session_memory
-```

-
-IMPORTANT: Be accurate and honest about what has and hasn't been verified.
-
-**Check these based on context (you can infer from the diff/spec):**
-- Base Branch targeting — check based on target_branch value
-- Type of Change (bug fix, feature, docs, refactor, test) — infer from diff and spec
-- Area (Frontend, Backend, Fullstack) — infer from changed file paths
-- Feature Toggle "N/A" — if the feature appears complete and not behind a flag
-- Breaking Changes "No" — if changes appear backward compatible
-
-**Leave UNCHECKED (these require human verification you cannot perform):**
-- "I've tested my changes locally" — you have not tested anything
-- "All CI checks pass" — CI has not run yet
-- "Windows/macOS/Linux tested" — requires manual testing on each platform
-- "All existing tests pass" — CI has not run yet
-- "New features include test coverage" — unless test files are clearly visible in the diff
-- "Bug fixes include regression tests" — unless test files are clearly visible in the diff
-
-**For platform/code quality checkboxes:**
-- "Used centralized platform/ module" — leave unchecked unless you can verify from the diff
-- "No hardcoded paths" — leave unchecked unless you can verify from the diff
-- "PR is small and focused (< 400 lines)" — check only if diff stats show < 400 lines changed
-
-**For the "I've synced with develop branch" checkbox:**
-- Leave unchecked — you cannot verify the sync status

-Custom MCP Tools for Auto-Claude Agents
-========================================
-
-This module provides custom MCP tools that agents can use for reliable
-operations on auto-claude data structures. These tools replace prompt-based
-JSON manipulation with guaranteed-correct operations.
-
-Benefits:
-- 100% reliable JSON operations (no malformed output)
-- Reduced context usage (tool definitions << prompt instructions)
-- Type-safe with proper error handling
-- Each agent only sees tools relevant to their role via allowed_tools
-
-Usage:
-    from auto_claude_tools import create_auto_claude_mcp_server, get_allowed_tools
-
-    # Create the MCP server
-    mcp_server = create_auto_claude_mcp_server(spec_dir, project_dir)
-
-    # Get allowed tools for a specific agent type
-    allowed_tools = get_allowed_tools("coder")
-
-    # Use in ClaudeAgentOptions
-    options = ClaudeAgentOptions(
-        mcp_servers={"auto-claude": mcp_server},

-Codebase Analyzer
-=================
-
-Automatically detects project structure, frameworks, and services.
-Supports monorepos with multiple services.
-
-Usage:
-    # Index entire project (creates project_index.json)
-    python auto-claude/analyzer.py --index
-
-    # Analyze specific service
-    python auto-claude/analyzer.py --service backend
-
-    # Output to specific file
-    python auto-claude/analyzer.py --index --output path/to/output.json
-
-The analyzer will:
-1. Detect if this is a monorepo or single project
-2. Find all services/packages and analyze each separately
-3. Map interdependencies between services
-4. Identify infrastructure (Docker, CI/CD)
-5. Document conventions (linting, testing)
-
-This module now serves as a facade to the modular analyzer system in the analyzers/ package.
-All actual implementation is in focused submodules for better maintainability.

-Smart Project Analyzer for Dynamic Security Profiles
-=====================================================
-
-FACADE MODULE: This module re-exports all functionality from the
-auto-claude/project/ package for backward compatibility.
-
-The implementation has been refactored into focused modules:
-- project/command_registry.py - Command registries
-- project/models.py - Data structures
-- project/config_parser.py - Config file parsing
-- project/stack_detector.py - Stack detection
-- project/framework_detector.py - Framework detection
-- project/structure_analyzer.py - Project structure analysis
-- project/analyzer.py - Main orchestration
-
-This file maintains the original API so existing imports continue to work.
-
-This system:
-1. Detects languages, frameworks, databases, and infrastructure
-2. Parses package.json scripts, Makefile targets, pyproject.toml scripts
-3. Builds a tailored security profile for the specific project
-4. Caches the profile for subsequent runs
-5. Can re-analyze when project structure changes
-
-The goal: Allow an AI developer to run any command that's legitimately
-needed for the detected tech stack, while blocking dangerous operations.

-Claude SDK Client Configuration
-===============================

-Functions for creating and configuring the Claude Agent SDK client.

-All AI interactions should use `create_client()` to ensure consistent OAuth authentication
-and proper tool/MCP configuration. For simple message calls without full agent sessions,
-use `create_simple_client()` from `core.simple_client`.
-
-The client factory now uses AGENT_CONFIGS from agents/tools_pkg/models.py as the
-single source of truth for phase-aware tool and MCP server configuration.

-Sentry Error Tracking for Python Backend
-=========================================
-
-Initializes Sentry for the Python backend with:
-- Privacy-preserving path masking (usernames removed)
-- Release tracking matching the Electron frontend
-- Environment variable configuration (same as frontend)
-
-Configuration:
-- SENTRY_DSN: Required to enable Sentry (same as frontend)
-- SENTRY_TRACES_SAMPLE_RATE: Performance monitoring sample rate (0-1, default: 0.1)
-- SENTRY_ENVIRONMENT: Override environment (default: auto-detected)
-
-Privacy Note:
-- Usernames are masked from all file paths
-- Project paths remain visible for debugging (this is expected)
-- No user identifiers are collected

-- Models and enums: workspace/models.py
-- Git utilities: workspace/git_utils.py
-- Setup functions: workspace/setup.py
-- Display functions: workspace/display.py
-- Finalization: workspace/finalization.py
-- Complex merge operations: remain here (workspace.py)

-AI_MERGE_SYSTEM_PROMPT = """You are an expert code merge assistant specializing in intelligent 3-way merges. Your task is to merge code changes from two branches while preserving all meaningful changes.
-
-CONTEXT:
-- "OURS" = current main branch (target for merge)
-- "THEIRS" = task worktree branch (changes being merged in)
-- "BASE" = common ancestor before changes
-
-MERGE STRATEGY:
-1. **Preserve all functional changes** - Include all features, bug fixes, and improvements from both versions
-2. **Combine independent changes** - If changes are in different functions/sections, include both
-3. **Resolve overlapping changes intelligently**:
-   - Prefer the more complete/updated implementation
-   - Combine logic if both versions add value
-   - When in doubt, favor the version that better addresses the task's intent
-4. **Maintain syntactic correctness** - Ensure the merged code is valid and compiles/runs
-5. **Preserve imports and dependencies** from both versions
-
-HANDLING COMMON PATTERNS:
-- New functions/classes: Include all from both versions
-- Modified functions: Merge changes logically, prefer more complete version
-- Imports: Union of all imports from both versions
-- Comments/Documentation: Include relevant documentation from both
-- Configuration: Merge settings, with conflict resolution favoring task-specific values
-
-CRITICAL RULES:
-- Output ONLY the merged code - no explanations, no prose, no markdown fences
-- If you cannot determine the correct merge, make a reasonable decision based on best practices
-- Never output error messages like "I need more context" - always provide a best-effort merge
-- Ensure the output is complete and syntactically valid code"""

-# Workspace Package
-
-This package contains the refactored workspace management code, organized for better maintainability and code quality.
-
-## Structure
-
-The original `workspace.py` file (2,868 lines) has been refactored into a modular package:
-
-```
-workspace/
-├── __init__.py          (130 lines) - Public API exports
-├── models.py            (133 lines) - Data classes and enums
-├── git_utils.py         (283 lines) - Git operations and utilities
-├── setup.py             (357 lines) - Workspace setup and initialization
-├── display.py           (136 lines) - UI display functions
-├── finalization.py      (494 lines) - Post-build finalization and user interaction
-└── README.md            - This file
-
-workspace.py             (2,295 lines) - Complex merge operations (remaining)
-```
-
-**Total refactored code:** 1,533 lines across 6 modules
-**Reduction in main file:** 573 lines (20% reduction)
-**Original file:** 2,868 lines
-
-## Modules
-
-### models.py
-Data structures and type definitions:
-- `WorkspaceMode` - How auto-claude should work (ISOLATED/DIRECT)
-- `WorkspaceChoice` - User's choice after build (MERGE/REVIEW/TEST/LATER)
-- `ParallelMergeTask` - Task for parallel file merging
-- `ParallelMergeResult` - Result of parallel merge
-- `MergeLock` - Context manager for merge locking
-- `MergeLockError` - Exception for lock failures
-
-### git_utils.py
-Git operations and utilities:
-- `has_uncommitted_changes()` - Check for unsaved work
-- `get_current_branch()` - Get active branch name
-- `get_existing_build_worktree()` - Check for existing spec worktree
-- `get_file_content_from_ref()` - Get file from git ref
-- `get_changed_files_from_branch()` - List changed files
-- `is_process_running()` - Check if PID is active
-- `is_binary_file()` - Check if file is binary
-- `validate_merged_syntax()` - Validate merged code syntax
-- `create_conflict_file_with_git()` - Create conflict markers with git
-
-**Constants:**
-- `MAX_FILE_LINES_FOR_AI` - Skip AI for large files (5000)
-- `MAX_PARALLEL_AI_MERGES` - Concurrent merge limit (5)
-- `BINARY_EXTENSIONS` - Set of binary file extensions
-- `MERGE_LOCK_TIMEOUT` - Lock timeout in seconds (300)
-
-### setup.py
-Workspace setup and initialization:
-- `choose_workspace()` - Let user choose workspace mode
-- `copy_spec_to_worktree()` - Copy spec files to worktree
-- `setup_workspace()` - Set up isolated or direct workspace
-- `ensure_timeline_hook_installed()` - Install git post-commit hook
-- `initialize_timeline_tracking()` - Register task for timeline tracking
-
-### display.py
-UI display functions:
-- `show_build_summary()` - Show summary of build changes
-- `show_changed_files()` - Show detailed file list
-- `print_merge_success()` - Print success message after merge
-- `print_conflict_info()` - Print conflict information
-
-### finalization.py
-Post-build finalization and user interaction:
-- `finalize_workspace()` - Handle post-build workflow
-- `handle_workspace_choice()` - Execute user's choice
-- `review_existing_build()` - Show existing build contents
-- `discard_existing_build()` - Delete build with confirmation
-- `check_existing_build()` - Check for existing build and offer options
-- `list_all_worktrees()` - List all spec worktrees
-- `cleanup_all_worktrees()` - Clean up all worktrees
-
-### workspace.py (parent module)
-Complex merge operations that remain in the main file:
-- `merge_existing_build()` - Merge existing build with intent-aware logic
-- AI-assisted merge functions (async operations)
-- Parallel merge orchestration
-- Git conflict resolution
-- Heuristic merge strategies
-
-These functions are tightly coupled and reference each other extensively, making them
-difficult to extract without significant refactoring of the merge system itself.
-
-## Usage
-
-### Import from workspace package
-```python
-from workspace import (
-    WorkspaceMode,
-    WorkspaceChoice,
-    setup_workspace,
-    finalize_workspace,
-    # ... other functions
-)
-```
-
-### Import specific modules
-```python
-from workspace.models import WorkspaceMode, MergeLock
-from workspace.git_utils import has_uncommitted_changes
-from workspace.setup import choose_workspace
-from workspace.display import show_build_summary
-from workspace.finalization import review_existing_build
-```
-
-### Import merge operations from parent
-```python
-# merge_existing_build is in the parent workspace.py module
-import workspace
-workspace.merge_existing_build(project_dir, spec_name)
-```
-
-## Backward Compatibility
-
-All existing imports continue to work:
-```python
-# Old style - still works
-from workspace import WorkspaceMode, setup_workspace, finalize_workspace
-
-# The refactoring maintains full backward compatibility
-```
-
-## Benefits
-
-1. **Improved Maintainability**: Each module has a clear, focused responsibility
-2. **Better Code Navigation**: Easier to find and understand specific functionality
-3. **Reduced Complexity**: Smaller files are easier to review and modify
-4. **Clear Separation**: Models, utilities, setup, display, and finalization are distinct
-5. **Backward Compatible**: No changes needed to existing code that imports from workspace
-6. **Type Safety**: Clear type hints throughout all modules
-
-## Testing
-
-Run the import test:
-```bash
-cd auto-claude
-python3 -c "from workspace import WorkspaceMode, setup_workspace; print('✓ Imports work')"
-```
-
-All functions are tested for import compatibility with existing CLI commands.

-Dependency Strategy Mapping
-============================
-
-Maps dependency types to sharing strategies for worktree creation.
-
-Each dependency ecosystem has different constraints:
-
-- **node_modules**: Safe to symlink. Node's resolution algorithm follows symlinks
-  correctly, and the directory is self-contained.
-
-- **venv / .venv**: Symlinked for fast worktree creation. CPython bug #106045
-  (pyvenv.cfg symlink resolution) does not affect typical usage (running scripts,
-  imports, pip). A health check after symlinking verifies usability; if it fails,
-  the caller falls back to recreating the venv.
-
-- **vendor (PHP)**: Safe to symlink. Composer's autoloader uses ``__DIR__``-relative
-  paths that resolve correctly through symlinks.
-
-- **cargo target / go modules**: Skip entirely. Rust's ``target/`` dir contains
-  per-machine build artifacts that must be rebuilt. Go uses a global module cache
-  (``$GOPATH/pkg/mod``), so there is nothing in-tree to share.

-Git Worktree Manager - Per-Spec Architecture
-=============================================
-
-Each spec gets its own worktree:
-- Worktree path: .auto-claude/worktrees/tasks/{spec-name}/
-- Branch name: auto-claude/{spec-name}
-
-This allows:
-1. Multiple specs to be worked on simultaneously
-2. Each spec's changes are isolated
-3. Branches persist until explicitly merged
-4. Clear 1:1:1 mapping: spec → worktree → branch

-1. Read the current file content above
-2. Identify what's wrong based on the error message
-3. Fix the JSON structure to match the expected format
-4. Write the corrected content to {output_file}

-Common fixes:
-- If the key is "ideas", rename it to "{ideation_type}"
-- If the JSON is invalid, fix the syntax errors
-- If there are no ideas, ensure the array has at least one idea object

-Implementation Plan Package
-============================

-Core data structures and utilities for subtask-based implementation plans.

-The key insight: Tests verify outcomes, but SUBTASKS define implementation steps.
-For complex multi-service features, implementation order matters.

-Workflow Types:
-- feature: Standard multi-service feature (phases = services)
-- refactor: Migration/refactor work (phases = stages: add, migrate, remove)
-- investigation: Bug hunting (phases = investigate, hypothesize, fix)
-- migration: Data migration (phases = prepare, test, execute, cleanup)
-- simple: Single-service enhancement (minimal overhead)
-
-Package Structure:
-- enums.py: All enumeration types (WorkflowType, PhaseType, etc.)
-- verification.py: Verification models for testing subtasks
-- subtask.py: Subtask model representing a unit of work
-- phase.py: Phase model grouping subtasks with dependencies
-- plan.py: ImplementationPlan model for complete feature plans

-Test Script for Memory Integration with LadybugDB
-=================================================
-
-This script tests the memory layer (graph + semantic search) to verify
-data is being saved and retrieved correctly from LadybugDB (embedded Kuzu).
-
-LadybugDB is an embedded graph database - no Docker required!
-
-Usage:
-    # Set environment variables first (or in .env file):
-    export GRAPHITI_ENABLED=true
-    export GRAPHITI_EMBEDDER_PROVIDER=ollama  # or: openai, voyage, azure_openai, google
-
-    # For Ollama (recommended - free, local):
-    export OLLAMA_EMBEDDING_MODEL=embeddinggemma
-    export OLLAMA_EMBEDDING_DIM=768
-
-    # For OpenAI:
-    export OPENAI_API_KEY=sk-...
-
-    # Run the test:
-    cd auto-claude
-    python integrations/graphiti/run_graphiti_memory_test.py
-
-    # Or run specific tests:
-    python integrations/graphiti/run_graphiti_memory_test.py --test connection
-    python integrations/graphiti/run_graphiti_memory_test.py --test save
-    python integrations/graphiti/run_graphiti_memory_test.py --test search
-    python integrations/graphiti/run_graphiti_memory_test.py --test ollama

-Test Script for Ollama Embedding Memory Integration
-====================================================
-
-This test validates that the memory system works correctly with local Ollama
-embedding models (like embeddinggemma, nomic-embed-text) for creating and
-retrieving memories in the hybrid RAG system.
-
-The test covers:
-1. Ollama embedding generation (direct API test)
-2. Creating memories with Ollama embeddings via GraphitiMemory
-3. Retrieving memories via semantic search
-4. Verifying the full create → store → retrieve cycle
-
-Prerequisites:
-    1. Install Ollama: https://ollama.ai/
-    2. Pull an embedding model:
-       ollama pull embeddinggemma    # 768 dimensions (lightweight)
-       ollama pull nomic-embed-text  # 768 dimensions (good quality)
-    3. Pull an LLM model (for knowledge graph construction):
-       ollama pull deepseek-r1:7b    # or llama3.2:3b, mistral:7b
-    4. Start Ollama server: ollama serve
-    5. Configure environment:
-       export GRAPHITI_ENABLED=true
-       export GRAPHITI_LLM_PROVIDER=ollama
-       export GRAPHITI_EMBEDDER_PROVIDER=ollama
-       export OLLAMA_LLM_MODEL=deepseek-r1:7b
-       export OLLAMA_EMBEDDING_MODEL=embeddinggemma
-       export OLLAMA_EMBEDDING_DIM=768
-
-NOTE: graphiti-core internally uses an OpenAI reranker for search ranking.
-      For full offline operation, set a dummy key: export OPENAI_API_KEY=dummy
-      The reranker will fail at search time, but embedding creation works.
-      For production, use OpenAI API key for best search quality.
-
-Usage:
-    cd apps/backend
-    python integrations/graphiti/run_ollama_embedding_test.py
-
-    # Run specific tests:
-    python integrations/graphiti/run_ollama_embedding_test.py --test embeddings
-    python integrations/graphiti/run_ollama_embedding_test.py --test create
-    python integrations/graphiti/run_ollama_embedding_test.py --test retrieve
-    python integrations/graphiti/run_ollama_embedding_test.py --test full-cycle

-Linear Updater - Python-Orchestrated Linear Updates
-====================================================
-
-Provides reliable Linear updates via focused mini-agent calls.
-Instead of relying on agents to remember Linear updates in long prompts,
-the Python orchestrator triggers small, focused agents at key transitions.
-
-Design Principles:
-- ONE task per spec (not one issue per subtask)
-- Python orchestrator controls when updates happen
-- Small prompts that can't lose context
-- Graceful degradation if Linear unavailable
-
-Status Flow:
-  Todo -> In Progress -> In Review -> (human) -> Done
-    |         |              |
-    |         |              +-- QA approved, awaiting human merge

-Session Memory System
-=====================
-
-Persists learnings between autonomous coding sessions to avoid rediscovering
-codebase patterns, gotchas, and insights.
-
-Architecture Decision:
-    Memory System Hierarchy:
-
-    PRIMARY: Graphiti (when GRAPHITI_ENABLED=true)
-        - Graph-based knowledge storage with LadybugDB (embedded Kuzu database)
-        - Semantic search across sessions
-        - Cross-project context retrieval
-        - Rich relationship modeling
-
-    FALLBACK: File-based (when Graphiti is disabled)
-        - Zero external dependencies (no database required)
-        - Human-readable files for debugging and inspection
-        - Guaranteed availability (no network/service failures)
-        - Simple backup and version control integration
-
-    The agent.py orchestrator uses save_session_memory() which:
-    1. Tries Graphiti first if enabled
-    2. Falls back to file-based if Graphiti is disabled or fails
-
-    This ensures memory is ALWAYS saved, regardless of configuration.
-
-Each spec has its own memory directory:
-    auto-claude/specs/001-feature/memory/
-        ├── codebase_map.json      # Key files and their purposes
-        ├── patterns.md            # Code patterns to follow

-# AI Resolver Module
-
-## Overview
-
-This module provides AI-based conflict resolution for the Auto Claude merge system. The code has been refactored from a single 665-line file into a well-organized package with clear separation of concerns.
-
-## Architecture
-
-### Module Structure
-
-```
-ai_resolver/
-├── __init__.py           # Public API exports
-├── resolver.py           # Core AIResolver class (406 lines)
-├── context.py            # ConflictContext data model (75 lines)
-├── prompts.py            # AI prompt templates (97 lines)
-├── parsers.py            # Code block parsing (101 lines)
-├── language_utils.py     # Language detection & location utils (70 lines)
-└── claude_client.py      # Claude SDK integration (92 lines)
-```
-
-### Refactoring Results
-
-- **Original file**: 665 lines in single ai_resolver.py
-- **New main file**: 39 lines (compatibility layer)
-- **Total new code**: 877 lines (includes better documentation and type hints)
-- **Reduction in main file**: 94% smaller
-
-### Design Principles
-
-1. **Separation of Concerns**: Each module has a single, well-defined responsibility
-2. **Backwards Compatibility**: Existing imports continue to work unchanged
-3. **Type Safety**: Comprehensive type hints throughout
-4. **Testability**: Smaller modules are easier to test in isolation
-5. **Documentation**: Clear docstrings for all public APIs
-
-## Module Responsibilities
-
-### `resolver.py`
-Core AIResolver class that orchestrates the resolution process:
-- Builds conflict contexts
-- Manages AI calls
-- Resolves single and multiple conflicts
-- Tracks usage statistics
-
-### `context.py`
-ConflictContext data model:
-- Encapsulates minimal context for AI prompts
-- Formats context for display
-- Estimates token usage
-
-### `prompts.py`
-Prompt template management:
-- System prompts
-- Single conflict merge prompts
-- Batch conflict merge prompts
-- Formatting functions
-
-### `parsers.py`
-Code extraction utilities:
-- Extract code blocks from AI responses
-- Validate code-like content
-- Handle batch responses
-
-### `language_utils.py`
-Language and location utilities:
-- Infer programming language from file paths
-- Check if code locations overlap
-
-### `claude_client.py`
-Claude SDK integration:
-- Factory function for Claude-based resolver
-- Async SDK client management
-- Error handling and logging
-
-## Usage
-
-### Basic Usage
-
-```python
-from merge.ai_resolver import AIResolver, create_claude_resolver
-
-# Create resolver with Claude integration
-resolver = create_claude_resolver()
-
-# Resolve a conflict
-result = resolver.resolve_conflict(
-    conflict=conflict_region,
-    baseline_code=original_code,
-    task_snapshots=snapshots
-)
-```
-
-### Custom AI Function
-
-```python
-from merge.ai_resolver import AIResolver
-
-def my_ai_function(system: str, user: str) -> str:
-    # Your AI integration here
-    return ai_response
-
-resolver = AIResolver(ai_call_fn=my_ai_function)
-```
-
-### Batch Resolution
-
-```python
-# Resolve multiple conflicts efficiently
-results = resolver.resolve_multiple_conflicts(
-    conflicts=conflict_list,
-    baseline_codes=baseline_dict,
-    task_snapshots=all_snapshots,
-    batch=True  # Enable batching for efficiency
-)
-```
-
-## Benefits of Refactoring
-
-1. **Maintainability**: Easier to understand and modify individual components
-2. **Testability**: Each module can be tested independently
-3. **Reusability**: Components like parsers and prompt formatters can be reused
-4. **Extensibility**: Easy to add new AI providers or parsing strategies
-5. **Code Quality**: Better organization leads to cleaner code
-6. **Documentation**: Each module has focused documentation
-
-## Backwards Compatibility
-
-The refactoring maintains 100% backwards compatibility:
-
-```python
-# These imports still work exactly as before
-from merge.ai_resolver import AIResolver, ConflictContext, create_claude_resolver
-from merge import AIResolver, create_claude_resolver
-```
-
-All existing code using the ai_resolver module continues to work without modification.

-Auto Merger
-===========
-
-Deterministic merge strategies that don't require AI intervention.
-
-This module implements the merge strategies identified by ConflictDetector
-as auto-mergeable. Each strategy is a pure Python algorithm that combines
-changes from multiple tasks in a predictable way.
-
-Strategies:
-- COMBINE_IMPORTS: Merge import statements from multiple tasks
-- HOOKS_FIRST: Add hooks at function start, then other changes
-- HOOKS_THEN_WRAP: Add hooks first, then wrap return in JSX
-- APPEND_FUNCTIONS: Add new functions after existing ones
-- APPEND_METHODS: Add new methods to class
-- COMBINE_PROPS: Merge JSX/object props
-- ORDER_BY_DEPENDENCY: Analyze dependencies and order appropriately
-- ORDER_BY_TIME: Apply changes in chronological order
-
-This file now serves as a backward-compatible entry point to the refactored
-auto_merger module. The actual implementation has been split into:
-- auto_merger/context.py - MergeContext dataclass
-- auto_merger/helpers.py - Helper utilities
-- auto_merger/strategies/ - Individual strategy implementations
-- auto_merger/merger.py - Main AutoMerger coordinator

-File Timeline Tracker
-=====================
-
-Intent-aware file evolution tracking for multi-agent merge resolution.
-
-This module implements the File-Centric Timeline Model that tracks:
-- Main branch evolution (human commits)
-- Task worktree modifications (AI agent changes)
-- Task branch points and intent
-- Pending task awareness for forward-compatible merges
-
-The key insight is that each file has a TIMELINE of changes from multiple sources,
-and the Merge AI needs this complete context to make intelligent decisions.
-
-Usage:
-    from merge.file_timeline import FileTimelineTracker
-
-    tracker = FileTimelineTracker(project_dir)
-
-    # When a task starts
-    tracker.on_task_start(
-        task_id="task-001-auth",
-        files_to_modify=["src/App.tsx"],
-        branch_point_commit="abc123",
-        task_intent="Add authentication via useAuth() hook"
-    )
-
-    # When human commits to main (via git hook)
-    tracker.on_main_branch_commit("def456")
-
-    # When getting merge context
-    context = tracker.get_merge_context("task-001-auth", "src/App.tsx")
-
-Architecture:
-    This module has been refactored into smaller, focused components:
-
-    - timeline_models.py: Data classes for timeline representation
-    - timeline_git.py: Git operations and queries
-    - timeline_persistence.py: Storage and loading of timelines
-    - timeline_tracker.py: Main service coordinating all components
-
-    This file serves as the main entry point and re-exports all public APIs
-    for backward compatibility.

-Implementation Planner
-======================
-
-Generates implementation plans from specs by analyzing the task and codebase.
-This replaces the initializer's test-generation with subtask-based planning.
-
-The planner:
-1. Reads the spec.md to understand what needs to be built
-2. Reads project_index.json to understand the codebase structure
-3. Reads context.json to know which files are relevant
-4. Determines the workflow type (feature, refactor, investigation, etc.)
-5. Generates phases and subtasks with proper dependencies
-6. Outputs implementation_plan.json
-
-Usage:
-    python auto-claude/planner.py --spec-dir auto-claude/specs/001-feature/

-# Command Registry Module
-
-This directory contains the refactored command registry system for dynamic security profiles.
-
-## Structure
-
-The original 771-line `command_registry.py` has been refactored into focused, maintainable modules:
-
-```
-command_registry/
-├── __init__.py              # Package exports (44 lines)
-├── base.py                  # Core shell commands (165 lines)
-├── languages.py             # Language-specific commands (151 lines)
-├── package_managers.py      # Package manager commands (40 lines)
-├── frameworks.py            # Framework-specific commands (155 lines)
-├── databases.py             # Database commands (121 lines)
-├── infrastructure.py        # DevOps/infrastructure commands (89 lines)
-├── cloud.py                 # Cloud provider CLIs (75 lines)
-├── code_quality.py          # Linting/security tools (40 lines)
-└── version_managers.py      # Version management tools (30 lines)
-```
-
-## Modules
-
-### base.py
-Core shell commands that are always safe regardless of project type, plus the validated commands that require extra security checks.
-
-**Exports:**
-- `BASE_COMMANDS` - Set of 126 core shell commands
-- `VALIDATED_COMMANDS` - Dict of 5 commands requiring validation
-
-### languages.py
-Programming language interpreters, compilers, and language-specific tooling.
-
-**Exports:**
-- `LANGUAGE_COMMANDS` - Dict mapping 19 languages to their commands
-
-### package_managers.py
-Package managers across different ecosystems (npm, pip, cargo, etc.).
-
-**Exports:**
-- `PACKAGE_MANAGER_COMMANDS` - Dict of 22 package managers
-
-### frameworks.py
-Web frameworks, testing frameworks, build tools, and framework-specific tooling.
-
-**Exports:**
-- `FRAMEWORK_COMMANDS` - Dict of 123 frameworks
-
-### databases.py
-Database clients, management tools, and ORMs.
-
-**Exports:**
-- `DATABASE_COMMANDS` - Dict of 20 database systems
-
-### infrastructure.py
-Containerization, orchestration, IaC, and DevOps tooling.
-
-**Exports:**
-- `INFRASTRUCTURE_COMMANDS` - Dict of 17 infrastructure tools
-
-### cloud.py
-Cloud provider CLIs and platform-specific tooling.
-
-**Exports:**
-- `CLOUD_COMMANDS` - Dict of 15 cloud providers
-
-### code_quality.py
-Linters, formatters, security scanners, and code analysis tools.
-
-**Exports:**
-- `CODE_QUALITY_COMMANDS` - Dict of 22 code quality tools
-
-### version_managers.py
-Runtime version management tools (nvm, pyenv, etc.).
-
-**Exports:**
-- `VERSION_MANAGER_COMMANDS` - Dict of 12 version managers
-
-## Usage
-
-### Direct Import from Package
-```python
-from project.command_registry import BASE_COMMANDS, LANGUAGE_COMMANDS
-```
-
-### Import from Specific Modules
-```python
-from project.command_registry.base import BASE_COMMANDS
-from project.command_registry.languages import LANGUAGE_COMMANDS
-```
-
-### Legacy Import (Backward Compatible)
-```python
-# Still works via the facade in project/command_registry.py
-from project.command_registry import BASE_COMMANDS
-```
-
-## Benefits
-
-1. **Maintainability** - Each module has a single, clear responsibility
-2. **Readability** - Smaller files are easier to understand and navigate
-3. **Extensibility** - New command categories can be added as new modules
-4. **Type Safety** - All modules include proper type hints
-5. **Documentation** - Each module is self-documenting with clear docstrings
-6. **Backward Compatibility** - Existing imports continue to work unchanged
-
-## Testing
-
-All imports have been verified to work correctly:
-- Direct package imports
-- Individual module imports
-- Backward compatibility with existing code (project_analyzer.py, etc.)
-- Data integrity (all 381 command definitions preserved)

-Smart Project Analyzer for Dynamic Security Profiles
-=====================================================
-
-FACADE MODULE: This module re-exports all functionality from the
-auto-claude/project/ package for backward compatibility.
-
-The implementation has been refactored into focused modules:
-- project/command_registry.py - Command registries
-- project/models.py - Data structures
-- project/config_parser.py - Config file parsing
-- project/stack_detector.py - Stack detection
-- project/framework_detector.py - Framework detection
-- project/structure_analyzer.py - Project structure analysis
-- project/analyzer.py - Main orchestration
-
-This file maintains the original API so existing imports continue to work.
-
-This system:
-1. Detects languages, frameworks, databases, and infrastructure
-2. Parses package.json scripts, Makefile targets, pyproject.toml scripts
-3. Builds a tailored security profile for the specific project
-4. Caches the profile for subsequent runs
-5. Can re-analyze when project structure changes
-
-The goal: Allow an AI developer to run any command that's legitimately
-needed for the detected tech stack, while blocking dangerous operations.

-## YOUR ROLE - QA FIX AGENT
-
-You are the **QA Fix Agent** in an autonomous development process. The QA Reviewer has found issues that must be fixed before sign-off. Your job is to fix ALL issues efficiently and correctly.
-
-**Key Principle**: Fix what QA found. Don't introduce new issues. Get to approval.
-
----
-
-## WHY QA FIX EXISTS
-
-The QA Agent found issues that block sign-off:
-- Missing migrations
-- Failing tests
-- Console errors
-- Security vulnerabilities
-- Pattern violations
-- Missing functionality
-
-You must fix these issues so QA can approve.
-
----
-
-## PHASE 0: LOAD CONTEXT (MANDATORY)
-
-```bash
-# 1. Read the QA fix request (YOUR PRIMARY TASK)
-cat QA_FIX_REQUEST.md
-
-# 2. Read the QA report (full context on issues)
-cat qa_report.md 2>/dev/null || echo "No detailed report"
-
-# 3. Read the spec (requirements)
-cat spec.md
-
-# 4. Read the implementation plan (see qa_signoff status)
-cat implementation_plan.json
-
-# 5. Check current state
-git status
-git log --oneline -5
-```
-
-**CRITICAL**: The `QA_FIX_REQUEST.md` file contains:
-- Exact issues to fix
-- File locations
-- Required fixes
-- Verification criteria
-
----
-
-## PHASE 1: PARSE FIX REQUIREMENTS
-
-From `QA_FIX_REQUEST.md`, extract:
-
-```
-FIXES REQUIRED:
-1. [Issue Title]
-   - Location: [file:line]
-   - Problem: [description]
-   - Fix: [what to do]
-   - Verify: [how QA will check]
-
-2. [Issue Title]
-   ...
-```
-
-Create a mental checklist. You must address EVERY issue.
-
----
-
-## PHASE 2: START DEVELOPMENT ENVIRONMENT
-
-```bash
-# Start services if needed
-chmod +x init.sh && ./init.sh
-
-# Verify running
-lsof -iTCP -sTCP:LISTEN | grep -E "node|python|next|vite"
-```
-
----
-
-## 🚨 CRITICAL: PATH CONFUSION PREVENTION 🚨
-
-**THE #1 BUG IN MONOREPOS: Doubled paths after `cd` commands**
-
-### The Problem
-
-After running `cd ./apps/frontend`, your current directory changes. If you then use paths like `apps/frontend/src/file.ts`, you're creating **doubled paths** like `apps/frontend/apps/frontend/src/file.ts`.
-
-### The Solution: ALWAYS CHECK YOUR CWD
-
-**BEFORE every git command or file operation:**
-
-```bash
-# Step 1: Check where you are
-pwd
-
-# Step 2: Use paths RELATIVE TO CURRENT DIRECTORY
-# If pwd shows: /path/to/project/apps/frontend
-# Then use: git add src/file.ts
-# NOT: git add apps/frontend/src/file.ts
-```
-
-### Examples
-
-**❌ WRONG - Path gets doubled:**
-```bash
-cd ./apps/frontend
-git add apps/frontend/src/file.ts  # Looks for apps/frontend/apps/frontend/src/file.ts
-```
-
-**✅ CORRECT - Use relative path from current directory:**
-```bash
-cd ./apps/frontend
-pwd  # Shows: /path/to/project/apps/frontend
-git add src/file.ts  # Correctly adds apps/frontend/src/file.ts from project root
-```
-
-**✅ ALSO CORRECT - Stay at root, use full relative path:**
-```bash
-# Don't change directory at all
-git add ./apps/frontend/src/file.ts  # Works from project root
-```
-
-### Mandatory Pre-Command Check
-
-**Before EVERY git add, git commit, or file operation in a monorepo:**
-
-```bash
-# 1. Where am I?
-pwd
-
-# 2. What files am I targeting?
-ls -la [target-path]  # Verify the path exists

-## 🚨 CRITICAL: WORKTREE ISOLATION 🚨
-
-**You may be in an ISOLATED GIT WORKTREE environment.**
-
-Check the "YOUR ENVIRONMENT" section at the top of this prompt. If you see an
-**"ISOLATED WORKTREE - CRITICAL"** section, you are in a worktree.
-
-### What is a Worktree?
-
-A worktree is a **complete copy of the project** isolated from the main project.
-This allows safe development without affecting the main branch.
-
-### Worktree Rules (CRITICAL)
-
-**If you are in a worktree, the environment section will show:**
-
-* **YOUR LOCATION:** The path to your isolated worktree
-* **FORBIDDEN PATH:** The parent project path you must NEVER `cd` to
-
-**CRITICAL RULES:**
-* **NEVER** `cd` to the forbidden parent path
-* **NEVER** use `cd ../..` to escape the worktree
-* **STAY** within your working directory at all times
-* **ALL** file operations use paths relative to your current location
-
-### Why This Matters
-
-Escaping the worktree causes:
-* ❌ Git commits going to the wrong branch
-* ❌ Files created/modified in the wrong location
-* ❌ Breaking worktree isolation guarantees
-* ❌ Losing the safety of isolated development
-
-### How to Stay Safe
-
-**Before ANY `cd` command:**
-
-```bash
-# 1. Check where you are
-pwd
-
-# 2. Verify the target is within your worktree
-# If pwd shows: /path/to/.auto-claude/worktrees/tasks/spec-name/
-# Then: cd ./apps/backend  ✅ SAFE
-# But:  cd /path/to/parent/project  ❌ FORBIDDEN - ESCAPES ISOLATION
-
-# 3. When in doubt, don't use cd at all
-# Use relative paths from your current directory instead
-git add ./apps/backend/file.py  # Works from anywhere in worktree
-```
-
-### The Golden Rule in Worktrees
-
-**If you're in a worktree, pretend the parent project doesn't exist.**
-
-Everything you need is in your worktree, accessible via relative paths.
-
----
-
-## PHASE 3: FIX ISSUES ONE BY ONE
-
-For each issue in the fix request:
-
-### 3.1: Read the Problem Area
-
-```bash
-# Read the file with the issue
-cat [file-path]
-```
-
-### 3.2: Understand What's Wrong
-
-- What is the issue?
-- Why did QA flag it?
-- What's the correct behavior?
-
-### 3.3: Implement the Fix
-
-Apply the fix as described in `QA_FIX_REQUEST.md`.
-
-**Follow these rules:**
-- Make the MINIMAL change needed
-- Don't refactor surrounding code
-- Don't add features
-- Match existing patterns
-- Test after each fix
-
-### 3.4: Verify the Fix Locally
-
-Run the verification from QA_FIX_REQUEST.md:
-
-```bash
-# Whatever verification QA specified
-[verification command]
-```
-
-### 3.5: Document
-
-```
-FIX APPLIED:
-- Issue: [title]
-- File: [path]
-- Change: [what you did]
-- Verified: [how]
-```
-
----
-
-## PHASE 4: RUN TESTS
-
-After all fixes are applied:
-
-```bash
-# Run the full test suite
-[test commands from project_index.json]
-
-# Run specific tests that were failing
-[failed test commands from QA report]
-```
-
-**All tests must pass before proceeding.**
-
----
-
-## PHASE 5: SELF-VERIFICATION
-
-Before committing, verify each fix from QA_FIX_REQUEST.md:
-
-```
-SELF-VERIFICATION:
-□ Issue 1: [title] - FIXED
-  - Verified by: [how you verified]
-□ Issue 2: [title] - FIXED
-  - Verified by: [how you verified]
-...
-
-ALL ISSUES ADDRESSED: YES/NO
-```
-
-If any issue is not fixed, go back to Phase 3.
-
----
-
-## PHASE 6: COMMIT FIXES
-
-### Path Verification (MANDATORY FIRST STEP)
-
-**🚨 BEFORE running ANY git commands, verify your current directory:**
-
-```bash
-# Step 1: Where am I?
-pwd
-
-# Step 2: What files do I want to commit?
-# If you changed to a subdirectory (e.g., cd apps/frontend),
-# you need to use paths RELATIVE TO THAT DIRECTORY, not from project root
-
-# Step 3: Verify paths exist
-ls -la [path-to-files]  # Make sure the path is correct from your current location
-
-# Example in a monorepo:
-# If pwd shows: /project/apps/frontend
-# Then use: git add src/file.ts
-# NOT: git add apps/frontend/src/file.ts (this would look for apps/frontend/apps/frontend/src/file.ts)
-```
-
-**CRITICAL RULE:** If you're in a subdirectory, either:
-- **Option A:** Return to project root: `cd [back to working directory]`
-- **Option B:** Use paths relative to your CURRENT directory (check with `pwd`)
-
-### Create the Commit
-
-```bash
-# FIRST: Make sure you're in the working directory root
-pwd  # Should match your working directory
-
-# Add all files EXCEPT .auto-claude directory (spec files should never be committed)
-git add . ':!.auto-claude'
-
-# If git add fails with "pathspec did not match", you have a path problem:
-# 1. Run pwd to see where you are
-# 2. Run git status to see what git sees
-# 3. Adjust your paths accordingly
-
-git commit -m "fix: Address QA issues (qa-requested)
-
-Fixes:
-- [Issue 1 title]
-- [Issue 2 title]
-- [Issue 3 title]
-
-Verified:
-- All tests pass
-- Issues verified locally
-
-QA Fix Session: [N]"
-```
-
-**CRITICAL**: The `:!.auto-claude` pathspec exclusion ensures spec files are NEVER committed.
-
-**NOTE**: Do NOT push to remote. All work stays local until user reviews and approves.
-
----
-
-## PHASE 7: UPDATE IMPLEMENTATION PLAN
-
-Update `implementation_plan.json` to signal fixes are complete:
-
-```json
-{
-  "qa_signoff": {
-    "status": "fixes_applied",
-    "timestamp": "[ISO timestamp]",
-    "fix_session": [session-number],
-    "issues_fixed": [
-      {
-        "title": "[Issue title]",
-        "fix_commit": "[commit hash]"
-      }
-    ],
-    "ready_for_qa_revalidation": true
-  }
-}
-```
-
----
-
-## PHASE 8: SIGNAL COMPLETION
-
-```
-=== QA FIXES COMPLETE ===
-
-Issues fixed: [N]
-
-1. [Issue 1] - FIXED
-   Commit: [hash]
-
-2. [Issue 2] - FIXED
-   Commit: [hash]
-
-All tests passing.
-Ready for QA re-validation.
-
-The QA Agent will now re-run validation.
-```
-
----
-
-## COMMON FIX PATTERNS
-
-### Missing Migration
-
-```bash
-# Create the migration
-# Django:
-python manage.py makemigrations
-
-# Rails:
-rails generate migration [name]
-
-# Prisma:
-npx prisma migrate dev --name [name]
-
-# Apply it
-[apply command]
-```
-
-### Failing Test
-
-1. Read the test file
-2. Understand what it expects
-3. Either fix the code or fix the test (if test is wrong)
-4. Run the specific test
-5. Run full suite
-
-### Console Error
-
-1. Open browser to the page
-2. Check console
-3. Fix the JavaScript/React error
-4. Verify no more errors
-
-### Security Issue
-
-1. Understand the vulnerability
-2. Apply secure pattern from codebase
-3. No hardcoded secrets
-4. Proper input validation
-5. Correct auth checks
-
-### Pattern Violation
-
-1. Read the reference pattern file
-2. Understand the convention
-3. Refactor to match pattern
-4. Verify consistency
-
----
-
-## KEY REMINDERS
-
-### Fix What Was Asked
-- Don't add features
-- Don't refactor
-- Don't "improve" code
-- Just fix the issues
-
-### Be Thorough
-- Every issue in QA_FIX_REQUEST.md
-- Verify each fix
-- Run all tests
-
-### Don't Break Other Things
-- Run full test suite
-- Check for regressions
-- Minimal changes only
-
-### Document Clearly
-- What you fixed
-- How you verified
-- Commit messages
-
-### Git Configuration - NEVER MODIFY
-**CRITICAL**: You MUST NOT modify git user configuration. Never run:
-- `git config user.name`
-- `git config user.email`
-
-The repository inherits the user's configured git identity. Do NOT set test users.
-
----
-
-## QA LOOP BEHAVIOR
-
-After you complete fixes:
-1. QA Agent re-runs validation
-2. If more issues → You fix again
-3. If approved → Done!
-
-Maximum iterations: 5
-
-After iteration 5, escalate to human.

-## YOUR ROLE - QUICK SPEC AGENT
-
-You are the **Quick Spec Agent** for simple tasks in the Auto-Build framework. Your job is to create a minimal, focused specification for straightforward changes that don't require extensive research or planning.
-
-**Key Principle**: Be concise. Simple tasks need simple specs. Don't over-engineer.
-
----
-
-## YOUR CONTRACT
-
-**Input**: Task description (simple change like UI tweak, text update, style fix)
-
-**Outputs**:
-- `spec.md` - Minimal specification (just essential sections)
-- `implementation_plan.json` - Simple plan with 1-2 subtasks
-
-**This is a SIMPLE task** - no research needed, no extensive analysis required.
-
----
-
-## PHASE 1: UNDERSTAND THE TASK
-
-Read the task description. For simple tasks, you typically need to:
-1. Identify the file(s) to modify
-2. Understand what change is needed
-3. Know how to verify it works
-
-That's it. No deep analysis needed.
-
----
-
-## PHASE 2: CREATE MINIMAL SPEC
-
-Create a concise `spec.md`:
-
-```bash
-cat > spec.md << 'EOF'
-# Quick Spec: [Task Name]
-
-## Task
-[One sentence description]
-
-## Files to Modify
-- `[path/to/file]` - [what to change]
-
-## Change Details
-[Brief description of the change - a few sentences max]
-
-## Verification
-- [ ] [How to verify the change works]
-
-## Notes
-[Any gotchas or considerations - optional]
-EOF
-```
-
-**Keep it short!** A simple spec should be 20-50 lines, not 200+.
-
----
-
-## PHASE 3: CREATE SIMPLE PLAN
-
-Create `implementation_plan.json`:
-
-```bash
-cat > implementation_plan.json << 'EOF'
-{
-  "spec_name": "[spec-name]",
-  "workflow_type": "simple",
-  "total_phases": 1,
-  "recommended_workers": 1,
-  "phases": [
-    {
-      "phase": 1,
-      "name": "Implementation",
-      "description": "[task description]",
-      "depends_on": [],
-      "subtasks": [
-        {
-          "id": "subtask-1-1",
-          "description": "[specific change]",
-          "service": "main",
-          "status": "pending",
-          "files_to_create": [],
-          "files_to_modify": ["[path/to/file]"],
-          "patterns_from": [],
-          "verification": {
-            "type": "manual",
-            "run": "[verification step]"
-          }
-        }
-      ]
-    }
-  ],
-  "metadata": {
-    "created_at": "[timestamp]",
-    "complexity": "simple",
-    "estimated_sessions": 1
-  }
-}
-EOF
-```
-
----
-
-## PHASE 4: VERIFY
-
-```bash
-# Check files exist
-ls -la spec.md implementation_plan.json
-
-# Check spec has content
-head -20 spec.md
-```
-
----
-
-## COMPLETION
-
-```
-=== QUICK SPEC COMPLETE ===
-
-Task: [description]
-Files: [count] file(s) to modify
-Complexity: SIMPLE
-
-Ready for implementation.
-```
-
----
-
-## CRITICAL RULES
-
-1. **KEEP IT SIMPLE** - No research, no deep analysis, no extensive planning
-2. **BE CONCISE** - Short spec, simple plan, one subtask if possible
-3. **JUST THE ESSENTIALS** - Only include what's needed to do the task
-4. **DON'T OVER-ENGINEER** - This is a simple task, treat it simply
-
----
-
-## EXAMPLES
-
-### Example 1: Button Color Change
-
-**Task**: "Change the primary button color from blue to green"
-
-**spec.md**:
-```markdown
-# Quick Spec: Button Color Change
-
-## Task
-Update primary button color from blue (#3B82F6) to green (#22C55E).
-
-## Files to Modify
-- `src/components/Button.tsx` - Update color constant
-
-## Change Details
-Change the `primaryColor` variable from `#3B82F6` to `#22C55E`.
-
-## Verification
-- [ ] Buttons appear green in the UI
-- [ ] No console errors
-```
-
-### Example 2: Text Update
-
-**Task**: "Fix typo in welcome message"
-
-**spec.md**:
-```markdown
-# Quick Spec: Fix Welcome Typo
-
-## Task
-Correct spelling of "recieve" to "receive" in welcome message.
-
-## Files to Modify
-- `src/pages/Home.tsx` - Fix typo on line 42
-
-## Change Details
-Find "You will recieve" and change to "You will receive".
-
-## Verification
-- [ ] Welcome message displays correctly
-```
-
----
-
-## BEGIN
-
-Read the task, create the minimal spec.md and implementation_plan.json.

-### Rules:
-1. **NEVER** use `cd {parent_project_path}` or any path starting with `{parent_project_path}`
-2. **NEVER** use absolute paths that reference the parent project
-3. **ALL** project files exist HERE via relative paths
-
-### Why This Matters:
-- Git commits made in the parent project go to the WRONG branch
-- File changes in the parent project escape isolation
-- This defeats the entire purpose of safe, isolated development
-
-### Correct Usage:
-```bash
-# ✅ CORRECT - Use relative paths from your worktree
-./prod/src/file.ts
-./apps/frontend/src/component.tsx
-
-# ❌ WRONG - These escape isolation!
-cd {parent_project_path}
-{parent_project_path}/prod/src/file.ts
-```

-If you see absolute paths in spec.md or context.json that reference `{parent_project_path}`,
-convert them to relative paths from YOUR current location.

-QA Validation Loop (Facade)
-============================
-
-This module provides backward compatibility by re-exporting the QA
-validation system that has been refactored into the qa/ package.
-
-For new code, prefer importing directly from the qa package:
-    from qa import run_qa_validation_loop, should_run_qa, is_qa_approved
-
-Module structure:
-    - qa/loop.py: Main QA orchestration loop
-    - qa/reviewer.py: QA reviewer agent session
-    - qa/fixer.py: QA fixer agent session
-    - qa/report.py: Issue tracking, reporting, escalation
-    - qa/criteria.py: Acceptance criteria and status management
-
-Enhanced features:
-- Iteration tracking with detailed history
-- Recurring issue detection (3+ occurrences → human escalation)
-- No-test project handling
-- Integration with validation strategy and risk classification

-   - Test framework limitations
-3. Update the spec or acceptance criteria if needed
-4. Run QA manually after making changes: `python run.py --spec {spec} --qa`

-## ⚠️ CRITICAL: PREVIOUS ITERATION FAILED - SELF-CORRECTION REQUIRED
-
-The previous QA session failed with the following error:
-
-**Error**: {previous_error.get("error_message", "Unknown error")}
-**Consecutive Failures**: {previous_error.get("consecutive_errors", 1)}
-
-### What Went Wrong
-
-You did NOT update the `implementation_plan.json` file with the required `qa_signoff` object.
-
-### Required Action
-
-After completing your QA review, you MUST:
-
-1. **Read the current implementation_plan.json**:
-   ```bash
-   cat {spec_dir}/implementation_plan.json
-   ```
-
-2. **Update it with your qa_signoff** by editing the JSON file to add/update the `qa_signoff` field:
-
-   If APPROVED:
-   ```json
-   {{
-     "qa_signoff": {{
-       "status": "approved",
-       "timestamp": "[current ISO timestamp]",
-       "qa_session": {qa_session},
-       "report_file": "qa_report.md",
-       "tests_passed": {{"unit": "X/Y", "integration": "X/Y", "e2e": "X/Y"}},
-       "verified_by": "qa_agent"
-     }}
-   }}
-   ```
-
-   If REJECTED:
-   ```json
-   {{
-     "qa_signoff": {{
-       "status": "rejected",
-       "timestamp": "[current ISO timestamp]",
-       "qa_session": {qa_session},
-       "issues_found": [
-         {{"type": "critical", "title": "[issue]", "location": "[file:line]", "fix_required": "[description]"}}
-       ],
-       "fix_request_file": "QA_FIX_REQUEST.md"
-     }}
-   }}
-   ```
-
-3. **Use the Edit tool or Write tool** to update the file. The file path is:
-   `{spec_dir}/implementation_plan.json`
-
-### FAILURE TO DO THIS WILL CAUSE ANOTHER ERROR
-
-This is attempt {previous_error.get("consecutive_errors", 1) + 1}. If you fail to update implementation_plan.json again, the QA process will be escalated to human review.

-Human Review Checkpoint System - Facade
-========================================
-
-This is a backward-compatible facade for the refactored review module.
-The actual implementation has been split into focused submodules:
-
-- review/state.py - ReviewState class and hash functions
-- review/diff_analyzer.py - Markdown extraction utilities
-- review/formatters.py - Display/summary functions
-- review/reviewer.py - Main orchestration logic
-- review/__init__.py - Public API exports
-
-For new code, prefer importing directly from the review package:
-    from review import ReviewState, run_review_checkpoint
-
-This facade maintains compatibility with existing imports:
-    from review import ReviewState, run_review_checkpoint
-
-Design Principles:
-- Block automatic build start until human approval is given
-- Persist approval state in review_state.json
-- Detect spec changes after approval (requires re-approval)
-- Support both interactive and auto-approve modes
-- Graceful Ctrl+C handling
-
-Usage:
-    # Programmatic use
-    from review import ReviewState, run_review_checkpoint
-
-    state = ReviewState.load(spec_dir)
-    if not state.is_approved():
-        state = run_review_checkpoint(spec_dir)

-- Safe workspace isolation (builds in separate workspace by default)
-- Parallel execution with Git worktrees
-- Smart recovery from interruptions
-- Linear integration for project management
-
-Usage:
-    python auto-claude/run.py --spec 001-initial-app
-    python auto-claude/run.py --spec 001
-    python auto-claude/run.py --list
-
-    # Workspace management
-    python auto-claude/run.py --spec 001 --merge     # Add completed build to project
-    python auto-claude/run.py --spec 001 --review    # See what was built
-    python auto-claude/run.py --spec 001 --discard   # Delete build (requires confirmation)
-
-Prerequisites:
-    - CLAUDE_CODE_OAUTH_TOKEN environment variable set (run: claude setup-token)
-    - Spec created via: claude /spec
-    - Claude Code CLI installed

-# AI Analyzer Package
-
-A modular, well-structured package for AI-powered code analysis using Claude Agent SDK.
-
-## Architecture
-
-The package follows a clean separation of concerns with the following modules:
-
-### Core Components
-
-```
-ai_analyzer/
-├── __init__.py           # Package exports
-├── models.py             # Data models and type definitions
-├── runner.py             # Main orchestrator
-├── analyzers.py          # Individual analyzer implementations
-├── claude_client.py      # Claude SDK client wrapper
-├── cost_estimator.py     # API cost estimation
-├── cache_manager.py      # Result caching
-├── result_parser.py      # JSON parsing utilities
-└── summary_printer.py    # Output formatting
-```
-
-### Module Responsibilities
-
-#### `models.py`
-- Data models: `AnalyzerType`, `CostEstimate`, `AnalysisResult`
-- Type definitions for vulnerabilities, bottlenecks, and code smells
-- Centralized type safety
-
-#### `runner.py`
-- `AIAnalyzerRunner`: Main orchestrator class
-- Coordinates analysis workflow
-- Manages analyzer execution and result aggregation
-- Calculates overall scores
-
-#### `analyzers.py`
-- Individual analyzer implementations:
-  - `CodeRelationshipsAnalyzer`
-  - `BusinessLogicAnalyzer`
-  - `ArchitectureAnalyzer`
-  - `SecurityAnalyzer`
-  - `PerformanceAnalyzer`
-  - `CodeQualityAnalyzer`
-- `AnalyzerFactory`: Creates analyzer instances
-- Each analyzer generates prompts and default results
-
-#### `claude_client.py`
-- `ClaudeAnalysisClient`: Wrapper for Claude SDK
-- Handles OAuth token validation
-- Creates security settings
-- Collects and returns responses
-
-#### `cost_estimator.py`
-- `CostEstimator`: Estimates API costs
-- Counts tokens based on project size
-- Provides cost breakdowns before analysis
-
-#### `cache_manager.py`
-- `CacheManager`: Handles result caching
-- 24-hour cache validity
-- Automatic cache invalidation
-
-#### `result_parser.py`
-- `ResultParser`: Parses JSON from Claude responses
-- Multiple parsing strategies (direct, markdown blocks, extraction)
-- Fallback to default values
-
-#### `summary_printer.py`
-- `SummaryPrinter`: Formats output
-- Prints scores, vulnerabilities, bottlenecks
-- Cost estimation display
-
-## Usage
-
-### From Python
-
-```python
-from pathlib import Path
-import json
-from ai_analyzer import AIAnalyzerRunner
-
-# Load project index
-project_dir = Path("/path/to/project")
-project_index = json.loads((project_dir / "comprehensive_analysis.json").read_text())
-
-# Create runner
-runner = AIAnalyzerRunner(project_dir, project_index)
-
-# Run analysis
-insights = await runner.run_full_analysis()
-
-# Print summary
-runner.print_summary(insights)
-```
-
-### From CLI
-
-```bash
-# Run full analysis
-python ai_analyzer_runner.py --project-dir /path/to/project
-
-# Run specific analyzers
-python ai_analyzer_runner.py --analyzers security performance
-
-# Skip cache
-python ai_analyzer_runner.py --skip-cache
-```
-
-## Design Principles
-
-1. **Single Responsibility**: Each module has one clear purpose
-2. **Dependency Injection**: Dependencies passed via constructors
-3. **Factory Pattern**: `AnalyzerFactory` for creating analyzer instances
-4. **Separation of Concerns**: UI, business logic, and data access separated
-5. **Type Safety**: Comprehensive type hints throughout
-6. **Error Handling**: Graceful degradation with defaults
-7. **Testability**: Modular design enables easy unit testing
-
-## Benefits of Refactoring
-
-- **Reduced complexity**: Main entry point reduced from 650 to 86 lines
-- **Improved maintainability**: Clear module boundaries
-- **Better testability**: Each component can be tested independently
-- **Enhanced readability**: Code organized by responsibility
-- **Easier extension**: Adding new analyzers or features is straightforward
-- **Type safety**: Comprehensive type hints aid development
-
-## Adding New Analyzers
-
-To add a new analyzer:
-
-1. Create analyzer class in `analyzers.py` extending `BaseAnalyzer`
-2. Implement `get_prompt()` and `get_default_result()` methods
-3. Add to `AnalyzerFactory.ANALYZER_CLASSES`
-4. Add to `AnalyzerType` enum in `models.py`
-5. Update `SummaryPrinter.ANALYZER_NAMES` if needed
-
-Example:
-
-```python
-class CustomAnalyzer(BaseAnalyzer):
-    def get_prompt(self) -> str:
-        return "Your analysis prompt here"
-
-    def get_default_result(self) -> dict[str, Any]:
-        return {"score": 0, "findings": []}
-```

-Bot Detection for GitHub Automation
-====================================
-
-Prevents infinite loops by detecting when the bot is reviewing its own work.
-
-Key Features:
-- Identifies bot user from configured token
-- Skips PRs authored by the bot
-- Skips re-reviewing bot commits
-- Implements "cooling off" period to prevent rapid re-reviews
-- Tracks reviewed commits to avoid duplicate reviews
-- In-progress tracking to prevent concurrent reviews
-- Stale review detection with automatic cleanup
-
-Usage:
-    detector = BotDetector(bot_token="ghp_...")
-
-    # Check if PR should be skipped
-    should_skip, reason = detector.should_skip_pr_review(pr_data, commits)
-    if should_skip:
-        print(f"Skipping PR: {reason}")
-        return
-
-    # Mark review as started (prevents concurrent reviews)
-    detector.mark_review_started(pr_number)
-
-    # Perform review...
-
-    # After successful review, mark as reviewed
-    detector.mark_reviewed(pr_number, head_sha)

-DEPRECATED: Review Confidence Scoring
-=====================================
-
-This module is DEPRECATED and will be removed in a future version.
-
-The confidence scoring approach has been replaced with EVIDENCE-BASED VALIDATION:
-- Instead of assigning confidence scores (0-100), findings now require concrete
-  code evidence proving the issue exists.
-- Simple rule: If you can't show the actual problematic code, don't report it.
-- Validation is binary: either the evidence exists in the file or it doesn't.
-
-For new code, use evidence-based validation in pydantic_models.py and models.py instead.
-
-Legacy Usage (deprecated):
-    scorer = ConfidenceScorer(learning_tracker=tracker)
-
-    # Score a finding
-    scored = scorer.score_finding(finding, context)
-    print(f"Confidence: {scored.confidence}%")
-    print(f"False positive risk: {scored.false_positive_risk}")
-
-    # Get explanation
-    print(scorer.explain_confidence(scored))
-
-Migration:
-    - Instead of `confidence: float`, use `evidence: str` with actual code snippets
-    - Instead of filtering by confidence threshold, verify evidence exists in file
-    - See pr_finding_validator.md for the new evidence-based approach

-File Locking for Concurrent Operations
-=====================================
-
-Thread-safe and process-safe file locking utilities for GitHub automation.
-Uses fcntl.flock() on Unix systems and msvcrt.locking() on Windows for proper
-cross-process locking.

-    async with FileLock("path/to/file.json", timeout=5.0):
-        # Do work with locked file
-        pass
-
-    # Atomic write with locking
-    async with locked_write("path/to/file.json", timeout=5.0) as f:
-        json.dump(data, f)

-Memory Integration for GitHub Automation
-=========================================
-
-Connects the GitHub automation system to the existing Graphiti memory layer for:
-- Cross-session context retrieval
-- Historical pattern recognition
-- Codebase gotchas and quirks
-- Similar past reviews and their outcomes
-
-Leverages the existing Graphiti infrastructure from:
-- integrations/graphiti/memory.py
-- integrations/graphiti/queries_pkg/graphiti.py
-- memory/graphiti_helpers.py
-
-Usage:
-    memory = GitHubMemoryIntegration(repo="owner/repo", state_dir=Path("..."))
-
-    # Before reviewing, get relevant context
-    context = await memory.get_review_context(
-        file_paths=["auth.py", "utils.py"],

-**IMPORTANT**: Pay special attention to the PR REVIEWS section above. These are formal code reviews from AI tools like CodeRabbit, Gemini Code Assist, Cursor, Greptile, etc. that may have identified issues in the recent changes. You should:
-1. Consider their findings when evaluating the code
-2. Create new findings for valid issues they identified that haven't been addressed
-3. Note if the recent commits addressed concerns raised in these reviews
-
-Analyze this follow-up review context and provide your structured response.

-Parallel Follow-up PR Reviewer
-===============================

-PR follow-up reviewer using Claude Agent SDK subagents for parallel specialist analysis.
-
-The orchestrator analyzes incremental changes and delegates to specialized agents:
-- resolution-verifier: Verifies previous findings are addressed
-- new-code-reviewer: Reviews new code for issues
-- comment-analyzer: Processes contributor and AI feedback
-
-Key Design:
-- AI decides which agents to invoke (NOT programmatic rules)
-- Subagents defined via SDK `agents={}` parameter
-- SDK handles parallel execution automatically
-- User-configured model from frontend settings (no hardcoding)

-Parallel Orchestrator PR Reviewer
-==================================
-
-PR reviewer using Claude Agent SDK subagents for parallel specialist analysis.
-
-The orchestrator analyzes the PR and delegates to specialized agents (security,
-quality, logic, codebase-fit, ai-triage) which run in parallel. Results are
-synthesized into a final verdict.
-
-Key Design:
-- AI decides which agents to invoke (NOT programmatic rules)
-- Subagents defined via SDK `agents={}` parameter
-- SDK handles parallel execution automatically
-- User-configured model from frontend settings (no hardcoding)

-Trust Escalation Model
-======================
-
-Progressive trust system that unlocks more autonomous actions as accuracy improves:
-
-- L0: Review-only (comment, no actions)
-- L1: Auto-apply labels based on triage
-- L2: Auto-close duplicates and spam
-- L3: Auto-merge trivial fixes (docs, typos)
-- L4: Full auto-fix with merge
-
-Trust increases with accuracy, decreases with overrides.

-2. **Quality** - Check for bugs, error handling, edge cases
-3. **Style** - Consistent naming, formatting, best practices
-4. **Tests** - Are changes tested? Test coverage concerns?

-Ideation Creation Orchestrator (Facade)
-========================================
-
-This is a facade that maintains backward compatibility with the original
-ideation_runner.py interface while delegating to the refactored modular
-components in the ideation/ package.
-
-AI-powered ideation generation for projects.
-Analyzes project context, existing features, and generates three types of ideas:
-1. Low-Hanging Fruit - Quick wins building on existing patterns
-2. UI/UX Improvements - Visual and interaction enhancements
-3. High-Value Features - Strategic features for target users
-
-Usage:
-    python auto-claude/ideation_runner.py --project /path/to/project
-    python auto-claude/ideation_runner.py --project /path/to/project --types low_hanging_fruit,high_value_features

-Spec Creation Orchestrator
-==========================
-
-Dynamic spec creation with complexity-based phase selection.
-The orchestrator uses AI to evaluate task complexity and adapts its process accordingly.
-
-Complexity Assessment:
-- By default, uses AI (complexity_assessor.md prompt) to analyze the task
-- AI considers: scope, integrations, infrastructure, knowledge requirements, risk
-- Falls back to heuristic analysis if AI assessment fails
-- Use --no-ai-assessment to skip AI and use heuristics only
-
-Complexity Tiers:
-- SIMPLE (1-2 files): Discovery → Quick Spec → Validate (3 phases)
-- STANDARD (3-10 files): Discovery → Requirements → Context → Spec → Plan → Validate (6 phases)
-- STANDARD + Research: Same as above but with research phase for external dependencies (7 phases)
-- COMPLEX (10+ files/integrations): Full 8-phase pipeline with research and self-critique
-
-The AI considers:
-- Number of files/services involved
-- External integrations and research requirements
-- Infrastructure changes (Docker, databases, etc.)
-- Whether codebase has existing patterns to follow
-- Risk factors and edge cases
-
-Usage:
-    python runners/spec_runner.py --task "Add user authentication"
-    python runners/spec_runner.py --interactive
-    python runners/spec_runner.py --continue 001-feature
-    python runners/spec_runner.py --task "Fix button color" --complexity simple

-Security Module for Auto-Build Framework
-=========================================
-
-Provides security validation for bash commands using dynamic allowlists
-based on project analysis.
-
-The security system has three layers:
-1. Base commands - Always allowed (core shell utilities)
-2. Stack commands - Detected from project structure (frameworks, languages)
-3. Custom commands - User-defined allowlist
-
-Public API
-----------
-Main functions:
-- bash_security_hook: Pre-tool-use hook for command validation
-- validate_command: Standalone validation function for testing
-- get_security_profile: Get or create security profile for a project
-- reset_profile_cache: Reset cached security profile
-
-Command parsing:
-- extract_commands: Extract command names from shell strings
-- split_command_segments: Split compound commands into segments
-
-Validators:
-- All validators are available via the VALIDATORS dict

-All functionality has been refactored into the security/ submodule:
-
-- security/validator.py - Command validation logic
-- security/parser.py - Command parsing utilities
-- security/profile.py - Security profile management
-- security/hooks.py - Security hook implementations
-- security/__init__.py - Public API exports
-
-See security/ directory for the actual implementation.
-
-The security system has three layers:
-1. Base commands - Always allowed (core shell utilities)
-2. Stack commands - Detected from project structure (frameworks, languages)
-3. Custom commands - User-defined allowlist

-See project_analyzer.py for the detection logic.

-Command Parsing Utilities
-==========================
-
-Functions for parsing and extracting commands from shell command strings.
-Handles compound commands, pipes, subshells, and various shell constructs.
-
-Windows Compatibility Note:
---------------------------
-On Windows, commands containing paths with backslashes can cause shlex.split()

-a fallback parser that extracts command names even from malformed commands,
-ensuring security validation can still proceed.

-Smart Rollback and Recovery System
-===================================
-
-Automatic recovery from build failures, stuck loops, and broken builds.
-Enables true "walk away" automation by detecting and recovering from common failure modes.
-
-Key Features:
-- Automatic rollback to last working state
-- Circular fix detection (prevents infinite loops)
-- Attempt history tracking across sessions
-- Smart retry with different approaches
-- Escalation to human when stuck

-
-**Subtask Description:** {subtask_desc}
-**Service:** {service}
-
-Before marking this subtask as complete, you MUST perform a thorough self-critique.
-This is NOT optional - it's a required quality gate.
-
-### STEP 1: Code Quality Checklist
-
-Review your implementation against these criteria:
-
-**Pattern Adherence:**
-- [ ] Follows patterns from reference files exactly: {", ".join(patterns_from) if patterns_from else "N/A"}
-- [ ] Variable naming matches codebase conventions
-- [ ] Imports organized correctly (grouped, sorted)
-- [ ] Code style consistent with existing files
-
-**Error Handling:**
-- [ ] Try-catch blocks where operations can fail
-- [ ] Meaningful error messages
-- [ ] Proper error propagation
-- [ ] Edge cases considered
-
-**Code Cleanliness:**
-- [ ] No console.log/print statements for debugging
-- [ ] No commented-out code blocks
-- [ ] No TODO comments without context
-- [ ] No hardcoded values that should be configurable
-
-**Best Practices:**
-- [ ] Functions are focused and single-purpose
-- [ ] No code duplication
-- [ ] Appropriate use of constants
-- [ ] Documentation/comments where needed
-
-### STEP 2: Implementation Completeness
-
-**Files Modified:**
-Expected: {", ".join(files_to_modify) if files_to_modify else "None"}
-Actual: {", ".join(files_modified) if files_modified else "None"}
-- [ ] All files_to_modify were actually modified
-- [ ] No unexpected files were modified
-
-**Files Created:**
-Expected: {", ".join(files_to_create) if files_to_create else "None"}
-- [ ] All files_to_create were actually created
-- [ ] Files follow naming conventions
-
-**Requirements:**
-- [ ] Subtask description requirements fully met
-- [ ] All acceptance criteria from spec considered
-- [ ] No scope creep - stayed within subtask boundaries
-
-### STEP 3: Potential Issues Analysis
-
-List any concerns, limitations, or potential problems with your implementation:
-
-1. [Issue 1, or "None identified"]
-2. [Issue 2, if any]
-3. [Issue 3, if any]
-
-Be honest. Finding issues now is better than discovering them during verification.
-
-### STEP 4: Improvements Made
-
-If you identified issues in your critique, list what you fixed:
-
-1. [Improvement 1, or "No fixes needed"]
-2. [Improvement 2, if applicable]
-3. [Improvement 3, if applicable]
-
-### STEP 5: Final Verdict
-
-**PROCEED:** [YES/NO - Only YES if all critical items pass]
-
-**REASON:** [Brief explanation of your decision]
-
-**CONFIDENCE:** [High/Medium/Low - How confident are you in this implementation?]
-
----
-
-## Instructions for Agent
-
-1. Work through each section methodically
-2. Check each box honestly - don't skip items
-3. If you find issues, FIX THEM before continuing
-4. Re-run this critique after fixes
-5. Only mark the subtask complete when verdict is YES with High confidence
-6. Document your critique results in your response
-
-Remember: The next session has no context. Quality issues you miss now will be harder to fix later.

-# Phases Module Refactoring
-
-## Overview
-
-The `phases.py` file (originally 720 lines) has been refactored into a well-organized subpackage for improved maintainability and code quality.
-
-## Structure
-
-### Before Refactoring
-```
-auto-claude/spec/
-└── phases.py (720 lines)
-    ├── PhaseResult dataclass
-    ├── PhaseExecutor class with 12 phase methods
-    └── Helper methods
-```
-
-### After Refactoring
-```
-auto-claude/spec/
-├── phases.py (14 lines - entry point)
-└── phases/
-    ├── __init__.py (19 lines)
-    ├── models.py (23 lines)
-    ├── executor.py (76 lines)
-    ├── discovery_phases.py (108 lines)
-    ├── requirements_phases.py (244 lines)
-    ├── spec_phases.py (199 lines)
-    ├── planning_phases.py (172 lines)
-    ├── utils.py (51 lines)
-    └── README.md
-```
-
-## Module Responsibilities
-
-### `models.py`
-- `PhaseResult` dataclass for phase execution results
-- `MAX_RETRIES` constant
-
-### `executor.py`
-- `PhaseExecutor` class that combines all phase mixins
-- Initialization and script execution delegation
-
-### `discovery_phases.py` (DiscoveryPhaseMixin)
-- `phase_discovery()` - Project structure analysis
-- `phase_context()` - Relevant file discovery
-
-### `requirements_phases.py` (RequirementsPhaseMixin)
-- `phase_historical_context()` - Graphiti knowledge graph integration
-- `phase_requirements()` - Interactive and automated requirements gathering
-- `phase_research()` - External integration validation
-
-### `spec_phases.py` (SpecPhaseMixin)
-- `phase_quick_spec()` - Simple task spec creation
-- `phase_spec_writing()` - Full spec.md document creation
-- `phase_self_critique()` - AI-powered spec validation
-
-### `planning_phases.py` (PlanningPhaseMixin)
-- `phase_planning()` - Implementation plan generation
-- `phase_validation()` - Final validation with auto-fix
-
-### `utils.py`
-- `run_script()` - Helper for executing Python scripts
-
-## Backward Compatibility
-
-The main `phases.py` file re-exports all public APIs, ensuring existing imports continue to work:
-
-```python
-from spec.phases import PhaseExecutor, PhaseResult, MAX_RETRIES
-```
-
-## Design Pattern
-
-The refactoring uses the **Mixin Pattern** to separate concerns:
-- Each mixin handles a logical group of related phases
-- The `PhaseExecutor` class inherits from all mixins
-- Shared utilities are extracted to separate modules
-
-## Benefits
-
-1. **Modularity**: Each file has a clear, focused responsibility
-2. **Maintainability**: Easier to locate and modify specific phase logic
-3. **Readability**: Smaller files are easier to understand
-4. **Testability**: Individual mixins can be tested in isolation
-5. **Extensibility**: New phases can be added without modifying existing code
-6. **Type Safety**: Proper type hints throughout
-
-## File Size Comparison
-
-- **Original**: 720 lines in single file
-- **Refactored**: 14-line entry point + 8 modular files (892 total lines including docs)
-- **Main Entry Point Reduction**: 98% smaller (720 → 14 lines)

-# Spec Validation System
-
-A modular validation framework for validating spec outputs at each checkpoint.
-
-## Architecture
-
-The validation system has been refactored into a clean, modular structure with clear separation of concerns:
-
-```
-validate_spec/
-├── __init__.py                 # Package exports
-├── models.py                   # ValidationResult dataclass
-├── schemas.py                  # Schema definitions and constants
-├── auto_fix.py                 # Auto-fix utilities
-├── spec_validator.py           # Main orchestrator
-└── validators/                 # Individual checkpoint validators
-    ├── __init__.py
-    ├── prereqs_validator.py
-    ├── context_validator.py
-    ├── spec_document_validator.py
-    └── implementation_plan_validator.py
-```
-
-## Components
-
-### Models (`models.py`)
-- **ValidationResult**: Data class representing validation results with errors, warnings, and suggested fixes
-
-### Schemas (`schemas.py`)
-- **IMPLEMENTATION_PLAN_SCHEMA**: Schema for implementation_plan.json
-- **CONTEXT_SCHEMA**: Schema for context.json
-- **PROJECT_INDEX_SCHEMA**: Schema for project_index.json
-- **SPEC_REQUIRED_SECTIONS**: Required sections in spec.md
-- **SPEC_RECOMMENDED_SECTIONS**: Recommended sections in spec.md
-
-### Validators (`validators/`)
-
-Each validator is responsible for a specific checkpoint:
-
-#### PrereqsValidator
-Validates that required prerequisites exist:
-- Spec directory exists
-- project_index.json exists
-
-#### ContextValidator
-Validates context.json structure:
-- File exists and is valid JSON
-- Contains required fields (task_description)
-- Warns about missing recommended fields
-
-#### SpecDocumentValidator
-Validates spec.md document:
-- File exists
-- Contains required sections (Overview, Workflow Type, Task Scope, Success Criteria)
-- Warns about missing recommended sections
-- Checks minimum content length
-
-#### ImplementationPlanValidator
-Validates implementation_plan.json:
-- File exists and is valid JSON
-- Contains required top-level fields
-- Valid workflow_type
-- Phases have correct structure
-- Subtasks have correct structure
-- No circular dependencies
-
-### Auto-Fix (`auto_fix.py`)
-Automated fixes for common issues:
-- Adds missing required fields to implementation_plan.json
-- Fixes missing phase/subtask IDs
-- Sets default status values
-
-### Main Validator (`spec_validator.py`)
-Orchestrates all validation checkpoints:
-- Initializes individual validators
-- Provides unified interface
-- Runs validation for specific checkpoints or all at once
-
-## Usage
-
-### Python API
-
-```python
-from validate_spec import SpecValidator, auto_fix_plan
-from pathlib import Path
-
-# Create validator
-spec_dir = Path("auto-claude/specs/001-feature")
-validator = SpecValidator(spec_dir)
-
-# Validate specific checkpoint
-result = validator.validate_context()
-if not result.valid:
-    print(f"Errors: {result.errors}")
-    print(f"Suggested fixes: {result.fixes}")
-
-# Validate all checkpoints
-results = validator.validate_all()
-all_valid = all(r.valid for r in results)
-
-# Auto-fix common issues
-if auto_fix_plan(spec_dir):
-    print("Auto-fixed implementation plan")
-```
-
-### CLI
-
-```bash
-# Validate all checkpoints
-python auto-claude/validate_spec.py --spec-dir auto-claude/specs/001-feature/ --checkpoint all
-
-# Validate specific checkpoint
-python auto-claude/validate_spec.py --spec-dir auto-claude/specs/001-feature/ --checkpoint context
-
-# Auto-fix and validate
-python auto-claude/validate_spec.py --spec-dir auto-claude/specs/001-feature/ --auto-fix --checkpoint plan
-
-# JSON output
-python auto-claude/validate_spec.py --spec-dir auto-claude/specs/001-feature/ --checkpoint all --json
-```
-
-## Imports
-
-### From Other Modules
-
-Other modules should import from the package:
-
-```python
-# Correct
-from validate_spec import SpecValidator, ValidationResult, auto_fix_plan
-from validate_spec.spec_validator import SpecValidator
-
-# Avoid (internal implementation details)
-from validate_spec.validators.context_validator import ContextValidator
-```
-
-## Benefits of Refactoring
-
-### Before
-- Single 633-line file
-- All logic mixed together
-- Hard to maintain and extend
-- Difficult to test individual components
-
-### After
-- Main entry point: 109 lines (83% reduction)
-- Clear separation of concerns
-- Each validator is independent and testable
-- Easy to add new validators
-- Schemas centralized and reusable
-- Better code organization and discoverability
-
-## Testing
-
-Each validator can be tested independently:
-
-```python
-from validate_spec.validators import ContextValidator
-from pathlib import Path
-
-validator = ContextValidator(Path("specs/001-feature"))
-result = validator.validate()
-assert result.valid
-```
-
-## Extension
-
-To add a new checkpoint validator:
-
-1. Create a new validator in `validators/`:
-```python
-# validators/new_checkpoint_validator.py
-from pathlib import Path
-from ..models import ValidationResult
-
-class NewCheckpointValidator:
-    def __init__(self, spec_dir: Path):
-        self.spec_dir = Path(spec_dir)
-
-    def validate(self) -> ValidationResult:
-        # Validation logic here
-        return ValidationResult(True, "new_checkpoint", [], [], [])
-```
-
-2. Add to `validators/__init__.py`:
-```python
-from .new_checkpoint_validator import NewCheckpointValidator
-__all__ = [..., "NewCheckpointValidator"]
-```
-
-3. Add method to `SpecValidator`:
-```python
-def validate_new_checkpoint(self) -> ValidationResult:
-    validator = NewCheckpointValidator(self.spec_dir)
-    return validator.validate()
-```
-
-4. Update CLI in main `validate_spec.py` if needed

-# Task Logger Package
-
-A modular, well-organized logging system for Auto Claude tasks with persistent storage and real-time UI updates.
-
-## Package Structure
-
-```
-task_logger/
-├── __init__.py          # Package exports and public API
-├── models.py            # Data models (LogPhase, LogEntryType, LogEntry, PhaseLog)
-├── logger.py            # Main TaskLogger class
-├── storage.py           # Log persistence and file I/O
-├── streaming.py         # Streaming marker emission for UI updates
-├── utils.py             # Utility functions (get_task_logger, etc.)
-├── capture.py           # StreamingLogCapture for agent sessions
-└── README.md            # This file
-```
-
-## Modules
-
-### models.py
-Contains the core data models:
-- `LogPhase`: Enum for execution phases (PLANNING, CODING, VALIDATION)
-- `LogEntryType`: Enum for log entry types (TEXT, TOOL_START, TOOL_END, etc.)
-- `LogEntry`: Dataclass representing a single log entry
-- `PhaseLog`: Dataclass representing logs for a single phase
-
-### logger.py
-Main logging implementation:
-- `TaskLogger`: Primary class for task logging with phase management, tool tracking, and event logging
-
-### storage.py
-Persistent storage functionality:
-- `LogStorage`: Handles JSON file storage and retrieval
-- `load_task_logs()`: Load logs from a spec directory
-- `get_active_phase()`: Get currently active phase
-
-### streaming.py
-Real-time UI updates:
-- `emit_marker()`: Emit streaming markers to stdout for UI consumption
-
-### utils.py
-Convenience utilities:
-- `get_task_logger()`: Get or create global logger instance
-- `clear_task_logger()`: Clear global logger
-- `update_task_logger_path()`: Update logger path after directory rename
-
-### capture.py
-Agent session integration:
-- `StreamingLogCapture`: Context manager for capturing agent output and logging it
-
-## Usage
-
-### Basic Usage
-
-```python
-from task_logger import TaskLogger, LogPhase
-
-# Create logger for a spec
-logger = TaskLogger(spec_dir)
-
-# Start a phase
-logger.start_phase(LogPhase.CODING, "Beginning implementation")
-
-# Log messages
-logger.log("Implementing feature X...")
-logger.log_info("Processing file: app.py")
-logger.log_success("Feature X completed!")
-logger.log_error("Failed to process file")
-
-# Track tool usage
-logger.tool_start("Read", "/path/to/file.py")
-logger.tool_end("Read", success=True, result="File read successfully")
-
-# End phase
-logger.end_phase(LogPhase.CODING, success=True)
-```
-
-### Using Global Logger
-
-```python
-from task_logger import get_task_logger
-
-# Get/create global logger
-logger = get_task_logger(spec_dir)
-logger.log("Using global logger instance")
-```
-
-### Capturing Agent Output
-
-```python
-from task_logger import StreamingLogCapture, LogPhase
-
-with StreamingLogCapture(logger, LogPhase.CODING) as capture:
-    async for msg in client.receive_response():
-        capture.process_message(msg)
-```
-
-### Loading Logs
-
-```python
-from task_logger import load_task_logs, get_active_phase
-
-# Load all logs
-logs = load_task_logs(spec_dir)
-
-# Get active phase
-active = get_active_phase(spec_dir)
-```
-
-## Design Principles
-
-### Separation of Concerns
-- **Models**: Pure data structures with no business logic
-- **Storage**: File I/O and persistence isolated from logging logic
-- **Logger**: Business logic for logging operations
-- **Streaming**: UI update mechanism separated from core logging
-- **Utils**: Helper functions for common patterns
-- **Capture**: Agent integration separated from core logger
-
-### Backwards Compatibility
-The refactored package maintains 100% backwards compatibility. All existing imports continue to work:
-
-```python
-# These imports still work (re-exported from task_logger.py)
-from task_logger import LogPhase, TaskLogger, get_task_logger
-```
-
-### Type Hints
-All functions and classes include comprehensive type hints for better IDE support and code clarity.
-
-### Testability
-Each module has a single responsibility, making it easier to test individual components.
-
-## Migration Guide
-
-**No migration needed!** The refactoring maintains full backwards compatibility.
-
-Existing code continues to work without changes:
-```python
-from task_logger import LogPhase, TaskLogger, get_task_logger
-```
-
-New code can import from specific modules if desired:
-```python
-from task_logger.models import LogPhase
-from task_logger.logger import TaskLogger
-from task_logger.utils import get_task_logger
-```
-
-## Benefits of Refactoring
-
-1. **Improved Maintainability**: 52-line entry point vs. 818-line monolith
-2. **Clear Separation**: Each module has a single, well-defined purpose
-3. **Better Testing**: Isolated modules are easier to unit test
-4. **Enhanced Readability**: Easier to find and understand specific functionality
-5. **Scalability**: New features can be added to appropriate modules
-6. **No Breaking Changes**: Full backwards compatibility maintained

+# Shows detailed information about app update checks and downloads
+# DEBUG_UPDATER=true
+
+# ============================================
+# SENTRY ERROR REPORTING
+# ============================================
+
+# Sentry DSN for anonymous error reporting
+# If not set, error reporting is completely disabled (safe for forks)
+#
+# For official builds: Set in CI/CD secrets
+# For local testing: Uncomment and add your DSN
+#
+# SENTRY_DSN=https://your-dsn@sentry.io/project-id
+
+# Force enable Sentry in development mode (normally disabled in dev)

+# Auto Claude UI - Frontend
+
+A modern Electron + React desktop application for the Auto Claude autonomous coding framework.
+
+## Prerequisites
+
+### Node.js v24.12.0 LTS (Required)
+
+This project requires **Node.js v24.12.0 LTS** (Latest LTS version as of December 2024).
+
+**Download:** https://nodejs.org/en/download/
+
+**Or install via command line:**
+
+**Windows:**
+```bash
+winget install OpenJS.NodeJS.LTS
+```
+
+**macOS:**
+```bash
+brew install node@24
+```
+
+**Linux (Ubuntu/Debian):**
+```bash
+curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -
+sudo apt install -y nodejs
+```
+
+**Linux (Fedora):**
+```bash
+sudo dnf install nodejs npm
+```
+
+> **IMPORTANT:** When installing Node.js on Windows, make sure to check:
+> - "Add to PATH"
+> - "npm package manager"
+
+**Verify installation:**
+```bash
+node --version  # Should output: v24.12.0
+npm --version   # Should output: 11.x.x or higher
+```
+
+> **Note:** npm is included with Node.js. If `npm` is not found after installing Node.js, you need to reinstall Node.js properly.
+
+## Quick Start
+
+```bash
+# Navigate to frontend directory
+cd apps/desktop
+
+# Install dependencies (includes native module rebuild)
+npm install
+
+# Start development server
+npm run dev
+```
+
+## Security
+
+This project maintains **0 vulnerabilities**. Run `npm audit` to verify.
+
+```bash
+npm audit
+# Expected output: found 0 vulnerabilities
+```
+
+## Architecture

+
+## Scripts
+
+| Command | Description |
+|---------|-------------|
+| `npm run dev` | Start development server with hot reload |
+| `npm run build` | Build for production |
+| `npm run package` | Build and package for current platform |
+| `npm run package:win` | Package for Windows |
+| `npm run package:mac` | Package for macOS |
+| `npm run package:linux` | Package for Linux |
+| `npm test` | Run unit tests |
+| `npm run test:watch` | Run tests in watch mode |
+| `npm run test:coverage` | Run tests with coverage |
+| `npm run lint` | Check for lint errors |
+| `npm run lint:fix` | Auto-fix lint errors |

+| `npm audit` | Check for security vulnerabilities |
+
+## Development Guidelines
+
+### Code Organization Principles
+
+1. **Feature-based Architecture**: Group related code by feature, not by type
+2. **Single Responsibility**: Each component/hook/store does one thing well
+3. **DRY (Don't Repeat Yourself)**: Extract reusable logic into shared modules
+4. **KISS (Keep It Simple)**: Prefer simple solutions over complex ones
+5. **SOLID Principles**: Apply object-oriented design principles
+
+### Naming Conventions
+
+| Type | Convention | Example |
+|------|------------|---------|
+| Components | PascalCase | `TaskCard.tsx` |
+| Hooks | camelCase with `use` prefix | `useTaskStore.ts` |
+| Stores | kebab-case with `-store` suffix | `task-store.ts` |
+| Types | PascalCase | `Task`, `TaskStatus` |
+| Constants | SCREAMING_SNAKE_CASE | `MAX_RETRIES` |
+
+### TypeScript Guidelines
+
+- **No implicit `any`**: Always type your variables and parameters
+- **Use `type` for simple objects**: Prefer `type` over `interface`
+- **Export types separately**: Use `export type` for type-only exports
+
+### Security Guidelines
+
+- **Never expose secrets**: API keys, tokens should stay in main process
+- **Validate IPC data**: Always validate data coming through IPC
+- **Use contextBridge**: Never expose Node.js APIs directly to renderer
+
+## Troubleshooting
+
+### npm not found
+
+If `npm` command is not recognized after installing Node.js:
+
+1. **Windows**: Reinstall Node.js from https://nodejs.org and ensure you check "Add to PATH"
+2. **macOS/Linux**: Add to your shell profile:
+   ```bash
+   export PATH="/usr/local/bin:$PATH"
+   ```
+3. Restart your terminal
+
+### Native module errors
+
+If you get errors about native modules (node-pty, etc.):
+
+```bash
+npm run rebuild
+```
+
+### Windows build tools required
+
+If electron-rebuild fails on Windows, install Visual Studio Build Tools:
+
+1. Download from https://visualstudio.microsoft.com/visual-cpp-build-tools/
+2. Select "Desktop development with C++" workload
+3. Restart terminal and run `npm install` again
+
+## Git Hooks
+
+This project uses Husky for Git hooks that run automatically:
+
+### Pre-commit Hook
+
+Runs before each commit:
+- **lint-staged**: Lints staged `.ts`/`.tsx` files
+- **typecheck**: TypeScript type checking
+- **lint**: ESLint checks
+- **npm audit**: Security vulnerability check (high severity)
+
+### Commit Message Format
+
+We use [Conventional Commits](https://www.conventionalcommits.org/). Your commit messages must follow this format:
+
+```
+type(scope): description
+```
+
+**Valid types:**
+| Type | Description |
+|------|-------------|
+| `feat` | A new feature |
+| `fix` | A bug fix |
+| `docs` | Documentation changes |
+| `style` | Code style (formatting, semicolons, etc.) |
+| `refactor` | Code refactoring (no feature/fix) |
+| `perf` | Performance improvements |
+| `test` | Adding or updating tests |
+| `build` | Build system or dependencies |
+| `ci` | CI/CD configuration |
+| `chore` | Maintenance tasks |
+| `revert` | Reverting a previous commit |
+
+**Examples:**
+```bash
+git commit -m "feat(tasks): add drag and drop support"
+git commit -m "fix(terminal): resolve scroll position issue"
+git commit -m "docs: update README with setup instructions"
+git commit -m "chore: update dependencies"
+```

+## YOUR ROLE - QA FIX AGENT
+
+You are the **QA Fix Agent** in an autonomous development process. The QA Reviewer has found issues that must be fixed before sign-off. Your job is to fix ALL issues efficiently and correctly.
+
+**Key Principle**: Fix what QA found. Don't introduce new issues. Get to approval.
+
+---
+
+## CRITICAL RULES
+
+### NEVER edit qa_report.md
+The `qa_report.md` file belongs to the QA Reviewer. You must NEVER modify it. The reviewer writes the verdict; you implement fixes. If you change the report status (e.g., to "FIXES_APPLIED"), the orchestrator won't recognize it as a valid verdict and your fixes will be wasted.
+
+### Fix in the PROJECT SOURCE, not in .auto-claude/specs/
+All your code changes, documentation additions, and new files must go into the **project source tree** (the actual codebase). Never create deliverable files inside `.auto-claude/specs/` — that directory contains gitignored metadata (spec, plan, QA report). The QA reviewer evaluates the project source, not spec artifacts.
+
+**Example:** If QA says "missing route inventory document", create it in the project root (e.g., `docs/route-policy.md` or `ROUTE_POLICY.md`), NOT in `.auto-claude/specs/route_access_policy.md`.
+
+### Fix CODE issues with CODE, not documentation
+If QA reports a missing test, write the test. If QA reports a code bug, fix the code. Don't write a markdown document explaining why the code is fine — write the code that makes it fine.
+
+### NEVER disagree with the QA Reviewer
+The QA Reviewer is the authority on what needs to be fixed. If they say a regex is too permissive, tighten the regex. If they say a test is missing, write the test. Do NOT decide the reviewer is wrong and skip the fix — that wastes a QA cycle and the reviewer will just fail you again with the same issue. Your job is to implement fixes, not to second-guess the review.
+
+If you genuinely believe the reviewer misread the code, fix the code to make the reviewer's concern impossible (e.g., add a comment explaining the design decision, add a test proving the behavior is correct, or tighten the code even if you think it's already fine). The goal is to get the reviewer to write "Status: PASSED" — not to convince them they were wrong.
+
+---
+
+## WHY QA FIX EXISTS
+
+The QA Agent found issues that block sign-off:
+- Missing migrations
+- Failing tests
+- Console errors
+- Security vulnerabilities
+- Pattern violations
+- Missing functionality
+
+You must fix these issues so QA can approve.
+
+---
+
+## PHASE 0: LOAD CONTEXT (MANDATORY)
+
+```bash
+# 1. Read the QA fix request (YOUR PRIMARY TASK)
+cat QA_FIX_REQUEST.md
+
+# 2. Read the QA report (full context on issues)
+cat qa_report.md 2>/dev/null || echo "No detailed report"
+
+# 3. Read the spec (requirements)
+cat spec.md
+
+# 4. Read the implementation plan (see qa_signoff status)
+cat implementation_plan.json
+
+# 5. Check current state
+git status
+git log --oneline -5
+```
+
+**CRITICAL**: The `QA_FIX_REQUEST.md` file contains:
+- Exact issues to fix
+- File locations
+- Required fixes
+- Verification criteria
+
+---
+
+## PHASE 1: PARSE FIX REQUIREMENTS
+
+From `QA_FIX_REQUEST.md`, extract:
+
+```
+FIXES REQUIRED:
+1. [Issue Title]
+   - Location: [file:line]
+   - Problem: [description]
+   - Fix: [what to do]
+   - Verify: [how QA will check]
+
+2. [Issue Title]
+   ...
+```
+
+Create a mental checklist. You must address EVERY issue.
+
+---
+
+## PHASE 2: START DEVELOPMENT ENVIRONMENT
+
+```bash
+# Start services if needed
+chmod +x init.sh && ./init.sh
+
+# Verify running
+lsof -iTCP -sTCP:LISTEN | grep -E "node|python|next|vite"
+```
+
+---
+
+## 🚨 CRITICAL: PATH CONFUSION PREVENTION 🚨
+
+**THE #1 BUG IN MONOREPOS: Doubled paths after `cd` commands**
+
+### The Problem
+
+After running `cd ./apps/desktop`, your current directory changes. If you then use paths like `apps/desktop/src/file.ts`, you're creating **doubled paths** like `apps/desktop/apps/desktop/src/file.ts`.
+
+### The Solution: ALWAYS CHECK YOUR CWD
+
+**BEFORE every git command or file operation:**
+
+```bash
+# Step 1: Check where you are
+pwd
+
+# Step 2: Use paths RELATIVE TO CURRENT DIRECTORY
+# If pwd shows: /path/to/project/apps/desktop
+# Then use: git add src/file.ts
+# NOT: git add apps/desktop/src/file.ts
+```
+
+### Examples
+
+**❌ WRONG - Path gets doubled:**
+```bash
+cd ./apps/desktop
+git add apps/desktop/src/file.ts  # Looks for apps/desktop/apps/desktop/src/file.ts
+```
+
+**✅ CORRECT - Use relative path from current directory:**
+```bash
+cd ./apps/desktop
+pwd  # Shows: /path/to/project/apps/desktop
+git add src/file.ts  # Correctly adds apps/desktop/src/file.ts from project root
+```
+
+**✅ ALSO CORRECT - Stay at root, use full relative path:**
+```bash
+# Don't change directory at all
+git add ./apps/desktop/src/file.ts  # Works from project root
+```
+
+### Mandatory Pre-Command Check
+
+**Before EVERY git add, git commit, or file operation in a monorepo:**
+
+```bash
+# 1. Where am I?
+pwd
+
+# 2. What files am I targeting?
+ls -la [target-path]  # Verify the path exists
+
+# 3. Only then run the command
+git add [verified-path]
+```
+
+**This check takes 2 seconds and prevents hours of debugging.**
+
+---
+
+## 🚨 CRITICAL: WORKTREE ISOLATION 🚨
+
+**You may be in an ISOLATED GIT WORKTREE environment.**
+
+Check the "YOUR ENVIRONMENT" section at the top of this prompt. If you see an
+**"ISOLATED WORKTREE - CRITICAL"** section, you are in a worktree.
+
+### What is a Worktree?
+
+A worktree is a **complete copy of the project** isolated from the main project.
+This allows safe development without affecting the main branch.
+
+### Worktree Rules (CRITICAL)
+
+**If you are in a worktree, the environment section will show:**
+
+* **YOUR LOCATION:** The path to your isolated worktree
+* **FORBIDDEN PATH:** The parent project path you must NEVER `cd` to
+
+**CRITICAL RULES:**
+* **NEVER** `cd` to the forbidden parent path
+* **NEVER** use `cd ../..` to escape the worktree
+* **STAY** within your working directory at all times
+* **ALL** file operations use paths relative to your current location
+
+### Why This Matters
+
+Escaping the worktree causes:
+* ❌ Git commits going to the wrong branch
+* ❌ Files created/modified in the wrong location
+* ❌ Breaking worktree isolation guarantees
+* ❌ Losing the safety of isolated development
+
+### How to Stay Safe
+
+**Before ANY `cd` command:**
+
+```bash
+# 1. Check where you are
+pwd
+
+# 2. Verify the target is within your worktree
+# If pwd shows: /path/to/.auto-claude/worktrees/tasks/spec-name/
+# Then: cd ./apps/desktop  ✅ SAFE
+# But:  cd /path/to/parent/project  ❌ FORBIDDEN - ESCAPES ISOLATION
+
+# 3. When in doubt, don't use cd at all
+# Use relative paths from your current directory instead
+git add ./apps/desktop/src/file.ts  # Works from anywhere in worktree
+```
+
+### The Golden Rule in Worktrees
+
+**If you're in a worktree, pretend the parent project doesn't exist.**
+
+Everything you need is in your worktree, accessible via relative paths.
+
+---
+
+## PHASE 3: FIX ISSUES ONE BY ONE
+
+For each issue in the fix request:
+
+### 3.1: Read the Problem Area
+
+```bash
+# Read the file with the issue
+cat [file-path]
+```
+
+### 3.2: Understand What's Wrong
+
+- What is the issue?
+- Why did QA flag it?
+- What's the correct behavior?
+
+### 3.3: Implement the Fix
+
+Apply the fix as described in `QA_FIX_REQUEST.md`.
+
+**Follow these rules:**
+- Make the MINIMAL change needed
+- Don't refactor surrounding code
+- Don't add features
+- Match existing patterns
+- Test after each fix
+
+### 3.4: Verify the Fix Locally
+
+Run the verification from QA_FIX_REQUEST.md:
+
+```bash
+# Whatever verification QA specified
+[verification command]
+```
+
+### 3.5: Document
+
+```
+FIX APPLIED:
+- Issue: [title]
+- File: [path]
+- Change: [what you did]
+- Verified: [how]
+```
+
+---
+
+## PHASE 4: RUN TESTS
+
+After all fixes are applied:
+
+```bash
+# Run the full test suite
+[test commands from project_index.json]
+
+# Run specific tests that were failing
+[failed test commands from QA report]
+```
+
+**All tests must pass before proceeding.**
+
+---
+
+## PHASE 5: SELF-VERIFICATION
+
+Before committing, verify each fix from QA_FIX_REQUEST.md:
+
+```
+SELF-VERIFICATION:
+□ Issue 1: [title] - FIXED
+  - Verified by: [how you verified]
+□ Issue 2: [title] - FIXED
+  - Verified by: [how you verified]
+...
+
+ALL ISSUES ADDRESSED: YES/NO
+```
+
+If any issue is not fixed, go back to Phase 3.
+
+---
+
+## PHASE 6: COMMIT FIXES
+
+### Path Verification (MANDATORY FIRST STEP)
+
+**🚨 BEFORE running ANY git commands, verify your current directory:**
+
+```bash
+# Step 1: Where am I?
+pwd
+
+# Step 2: What files do I want to commit?
+# If you changed to a subdirectory (e.g., cd apps/desktop),
+# you need to use paths RELATIVE TO THAT DIRECTORY, not from project root
+
+# Step 3: Verify paths exist
+ls -la [path-to-files]  # Make sure the path is correct from your current location
+
+# Example in a monorepo:
+# If pwd shows: /project/apps/desktop
+# Then use: git add src/file.ts
+# NOT: git add apps/desktop/src/file.ts (this would look for apps/desktop/apps/desktop/src/file.ts)
+```
+
+**CRITICAL RULE:** If you're in a subdirectory, either:
+- **Option A:** Return to project root: `cd [back to working directory]`
+- **Option B:** Use paths relative to your CURRENT directory (check with `pwd`)
+
+### Create the Commit
+
+```bash
+# FIRST: Make sure you're in the working directory root
+pwd  # Should match your working directory
+
+# Add all files EXCEPT .auto-claude directory (spec files should never be committed)
+git add . ':!.auto-claude'
+
+# If git add fails with "pathspec did not match", you have a path problem:
+# 1. Run pwd to see where you are
+# 2. Run git status to see what git sees
+# 3. Adjust your paths accordingly
+
+git commit -m "fix: Address QA issues (qa-requested)
+
+Fixes:
+- [Issue 1 title]
+- [Issue 2 title]
+- [Issue 3 title]
+
+Verified:
+- All tests pass
+- Issues verified locally
+
+QA Fix Session: [N]"
+```
+
+**CRITICAL**: The `:!.auto-claude` pathspec exclusion ensures spec files are NEVER committed.
+
+**NOTE**: Do NOT push to remote. All work stays local until user reviews and approves.
+
+---
+
+## PHASE 7: UPDATE IMPLEMENTATION PLAN
+
+Update `implementation_plan.json` to signal fixes are complete:
+
+```json
+{
+  "qa_signoff": {
+    "status": "fixes_applied",
+    "timestamp": "[ISO timestamp]",
+    "fix_session": [session-number],
+    "issues_fixed": [
+      {
+        "title": "[Issue title]",
+        "fix_commit": "[commit hash]"
+      }
+    ],
+    "ready_for_qa_revalidation": true
+  }
+}
+```
+
+---
+
+## PHASE 8: SIGNAL COMPLETION
+
+```
+=== QA FIXES COMPLETE ===
+
+Issues fixed: [N]
+
+1. [Issue 1] - FIXED
+   Commit: [hash]
+
+2. [Issue 2] - FIXED
+   Commit: [hash]
+
+All tests passing.
+Ready for QA re-validation.
+
+The QA Agent will now re-run validation.
+```
+
+---
+
+## COMMON FIX PATTERNS
+
+### Missing Migration
+
+```bash
+# Create the migration
+# Django:
+python manage.py makemigrations
+
+# Rails:
+rails generate migration [name]
+
+# Prisma:
+npx prisma migrate dev --name [name]
+
+# Apply it
+[apply command]
+```
+
+### Failing Test
+
+1. Read the test file
+2. Understand what it expects
+3. Either fix the code or fix the test (if test is wrong)
+4. Run the specific test
+5. Run full suite
+
+### Console Error
+
+1. Open browser to the page
+2. Check console
+3. Fix the JavaScript/React error
+4. Verify no more errors
+
+### Security Issue
+
+1. Understand the vulnerability
+2. Apply secure pattern from codebase
+3. No hardcoded secrets
+4. Proper input validation
+5. Correct auth checks
+
+### Pattern Violation
+
+1. Read the reference pattern file
+2. Understand the convention
+3. Refactor to match pattern
+4. Verify consistency
+
+---
+
+## KEY REMINDERS
+
+### Fix What Was Asked
+- Don't add features
+- Don't refactor
+- Don't "improve" code
+- Just fix the issues
+
+### Be Thorough
+- Every issue in QA_FIX_REQUEST.md
+- Verify each fix
+- Run all tests
+
+### Don't Break Other Things
+- Run full test suite
+- Check for regressions
+- Minimal changes only
+
+### Document Clearly
+- What you fixed
+- How you verified
+- Commit messages
+
+### Files You Must NEVER Edit
+- `qa_report.md` — belongs to the QA Reviewer exclusively
+- `spec.md` — the specification is frozen during QA
+
+### Write Deliverables to the Project, Not Spec Artifacts
+- All new files (docs, tests, code) go in the project source tree
+- NEVER create deliverable files in `.auto-claude/specs/` — that directory is gitignored metadata
+
+### Git Configuration - NEVER MODIFY
+**CRITICAL**: You MUST NOT modify git user configuration. Never run:
+- `git config user.name`
+- `git config user.email`
+
+The repository inherits the user's configured git identity. Do NOT set test users.
+
+---
+
+## QA LOOP BEHAVIOR
+
+After you complete fixes:
+1. QA Agent re-runs validation
+2. If more issues → You fix again
+3. If approved → Done!
+
+Maximum iterations: 5
+
+After iteration 5, escalate to human.

+## YOUR ROLE - AGENTIC QA ORCHESTRATOR
+
+You are the **Agentic QA Orchestrator** for the Auto-Build framework. You drive the QA validation loop autonomously — spawning reviewer and fixer subagents, interpreting their findings, and deciding when the build is good enough to ship.
+
+Unlike procedural QA loops that brute-force up to 50 iterations, you REASON about each review cycle and make intelligent decisions about what to fix, what to accept, and when to stop.
+
+---
+
+## YOUR TOOLS
+
+### Filesystem Tools
+- **Read** — Read project files, spec, implementation plan, QA reports
+- **Write** — Write QA reports, escalation documents
+- **Glob** — Find files by pattern
+- **Grep** — Search file contents
+
+### SpawnSubagent Tool
+Delegates work to QA specialist agents:
+
+```
+SpawnSubagent({
+  agent_type: "qa_reviewer" | "qa_fixer",
+  task: "Clear description of what the subagent should do",
+  context: "Relevant context (spec, prior review findings, specific focus areas)",
+  expect_structured_output: true/false
+})
+```
+
+**Available Subagent Types:**
+
+| Type | Purpose | Notes |
+|------|---------|-------|
+| `qa_reviewer` | Review implementation against spec | Has browser/test tools |
+| `qa_fixer` | Fix issues found by reviewer | Has full write access |
+
+---
+
+## YOUR WORKFLOW
+
+### Phase 1: Pre-flight Check
+
+Before starting QA:
+1. Read `implementation_plan.json` — verify all subtasks have status "completed"
+2. Read `spec.md` — understand what was supposed to be built
+3. Check for `QA_FIX_REQUEST.md` — human feedback takes priority
+
+If human feedback exists:
+1. Spawn `qa_fixer` with the human feedback as primary context
+2. After fixes, proceed to normal review
+
+### Phase 2: Initial Review
+
+Spawn `qa_reviewer` with comprehensive context:
+```
+SpawnSubagent({
+  agent_type: "qa_reviewer",
+  task: "Review the implementation against the specification",
+  context: "Spec: [spec.md content]\nPlan: [implementation_plan.json]\nProject: [projectDir]",
+  expect_structured_output: false
+})
+```
+
+The reviewer writes `qa_report.md` and updates `implementation_plan.json` with a `qa_signoff` object.
+
+### Phase 3: Interpret Results
+
+Read the `qa_signoff` from `implementation_plan.json`:
+
+- **Status: approved** → Build passes. Write final QA report. Done.
+- **Status: rejected** → Analyze the issues (see Phase 4)
+- **No signoff written** → Reviewer failed to update the file. Retry with explicit instructions.
+
+### Phase 4: Triage Issues
+
+When the reviewer rejects, classify each issue:
+
+**Critical Issues** (must fix):
+- Functionality doesn't match spec requirements
+- Tests fail or are missing for core features
+- Security vulnerabilities
+- Data corruption risks
+
+**Cosmetic Issues** (can accept):
+- Code style preferences
+- Minor naming suggestions
+- Documentation formatting
+- Non-functional improvements
+
+**Decision Framework:**
+- If ONLY cosmetic issues → approve the build (write qa_signoff: approved)
+- If critical issues exist → spawn qa_fixer with targeted guidance
+- If the same critical issue appears 3+ times → escalate to human
+
+### Phase 5: Fix Cycle
+
+When fixes are needed:
+1. Extract the critical issues from the review
+2. Spawn `qa_fixer` with SPECIFIC guidance:
+   ```
+   SpawnSubagent({
+     agent_type: "qa_fixer",
+     task: "Fix these specific issues: [list]",
+     context: "Issue 1: [description + location + expected fix]\nIssue 2: ...\n\nDo NOT change anything else.",
+     expect_structured_output: false
+   })
+   ```
+3. After fixes, re-review (go to Phase 2)
+
+### Phase 6: Convergence
+
+Track iteration count. Your goal is to converge quickly:
+
+| Iteration | Action |
+|-----------|--------|
+| 1-2 | Normal review/fix cycle |
+| 3-4 | Focus only on critical issues, accept cosmetic ones |
+| 5+ | If critical issues persist, escalate to human |
+
+**Maximum 5 iterations** — if still failing after 5, write an escalation report.
+
+---
+
+## QUALITY GATES
+
+### Approval Criteria
+Approve when ALL of these are true:
+- Core functionality matches the spec's acceptance criteria
+- No test failures (if tests exist)
+- No security vulnerabilities
+- Implementation follows project conventions
+
+### Acceptable Imperfections
+These should NOT block approval:
+- Missing optional features (if spec marks them as optional)
+- Code style deviations (if functionality is correct)
+- Missing edge case handling for unlikely scenarios
+- Performance optimizations that aren't in the spec
+
+---
+
+## ESCALATION
+
+When escalating to human review, write `QA_ESCALATION.md`:
+
+```markdown
+# QA Escalation Report
+
+## Summary
+[Why automated QA cannot resolve this]
+
+## Recurring Issues
+[List issues that keep appearing despite fixes]
+
+## Iterations Attempted
+[Count and brief summary of each cycle]
+
+## Recommendation
+[What the human should look at specifically]
+```
+
+---
+
+## ADAPTIVE BEHAVIOR
+
+### When the reviewer gives vague feedback
+- Re-spawn with more specific instructions: "Focus on [specific area]. Check [specific file]. Verify [specific behavior]."
+
+### When the fixer introduces new issues
+- This is common. The next review cycle will catch them.
+- If it happens repeatedly, tell the fixer to make MINIMAL changes.

+1. **Read the spec first** — Everything is judged against the specification
+2. **Triage before fixing** — Not every issue is worth a fix cycle
+3. **Maximum 5 iterations** — Escalate if you can't converge
+4. **Be specific with fixers** — Vague "fix the issues" leads to thrashing
+5. **Approve when good enough** — Perfect is the enemy of shipped
+6. **Track recurring issues** — Same issue 3+ times = escalate, don't retry

+### Be Pragmatic About Documentation Artifacts
+- **Code IS documentation.** If the spec says "produce a route inventory" and the code has a `PUBLIC_ROUTES` constant that IS the inventory, that counts. Don't require a separate markdown document when the code itself satisfies the intent.
+- **Focus on functional requirements over process artifacts.** If the implementation works correctly, is centralized, and is testable, don't block sign-off because a separate strategy document doesn't exist. Code comments, constant names, and test descriptions serve as documentation.

+- **You MUST run available test suites**, not just read test files. Reading a test file tells you what it claims to verify; running it tells you whether it actually passes.

+## YOUR ROLE - AGENTIC SPEC ORCHESTRATOR
+
+You are the **Agentic Spec Orchestrator** for the Auto-Build framework. You drive the entire spec creation pipeline autonomously — assessing complexity, delegating to specialist subagents, and assembling the final specification.
+
+Unlike procedural orchestrators, you REASON about each step and adapt your strategy based on results. You have tools to read/write files and a `SpawnSubagent` tool to delegate specialist work.
+
+---
+
+## YOUR TOOLS
+
+### Filesystem Tools
+- **Read** — Read project files to understand the codebase
+- **Write** — Write spec output files (spec.md, implementation_plan.json, etc.)
+- **Glob** — Find files by pattern
+- **Grep** — Search file contents
+- **WebFetch** / **WebSearch** — Research documentation when needed
+
+### SpawnSubagent Tool
+Delegates work to specialist agents. Each subagent runs independently with its own tools and system prompt. You receive the result (text or structured output) back in your context.
+
+```
+SpawnSubagent({
+  agent_type: "complexity_assessor" | "spec_discovery" | "spec_gatherer" |
+              "spec_researcher" | "spec_writer" | "spec_critic" | "spec_validation",
+  task: "Clear description of what the subagent should do",
+  context: "Relevant context from prior steps (accumulated findings, requirements, etc.)",
+  expect_structured_output: true/false
+})
+```
+
+**Available Subagent Types:**
+
+| Type | Purpose | Structured Output? |
+|------|---------|-------------------|
+| `complexity_assessor` | Assess task complexity (simple/standard/complex) | Yes (JSON) |
+| `spec_discovery` | Analyze project structure, tech stack, conventions | No (writes context.json) |
+| `spec_gatherer` | Gather and validate requirements from task description | No (writes requirements.json) |
+| `spec_researcher` | Research implementation approaches, external APIs, libraries | No (writes research.json) |
+| `spec_writer` | Write the specification (spec.md) and implementation plan | No (writes files) |
+| `spec_critic` | Review spec for completeness, technical feasibility, gaps | No (writes critique) |
+| `spec_validation` | Final validation of spec.md and implementation_plan.json | No (writes validation) |
+
+---
+
+## YOUR WORKFLOW
+
+### Phase 1: Assess Complexity
+
+Start by assessing the task's complexity. You can either:
+
+**Option A: Self-assess** (for obviously simple tasks)
+- If the task description is under 30 words AND matches simple patterns (typo fix, color change, text update), assess it yourself as SIMPLE.
+
+**Option B: Delegate to complexity assessor** (default)
+```
+SpawnSubagent({
+  agent_type: "complexity_assessor",
+  task: "Assess the complexity of: [task description]",
+  context: "[project index if available]",
+  expect_structured_output: true
+})
+```
+
+The result gives you `{ complexity, confidence, reasoning, needs_research, needs_self_critique }`.
+
+### Phase 2: Route by Complexity
+
+Based on the assessment, choose your workflow:
+
+#### SIMPLE Tasks
+1. Read the specific files that need changing (use Glob/Read — don't scan everything)
+2. Write `spec.md` yourself (short, focused — 20-50 lines)
+3. Write `implementation_plan.json` yourself (1 phase, 1-3 subtasks)
+4. Spawn `spec_validation` to verify the spec is complete
+5. Done
+
+#### STANDARD Tasks
+1. Spawn `spec_discovery` → receives context.json
+2. Spawn `spec_gatherer` → receives requirements.json
+3. Spawn `spec_writer` with accumulated context → receives spec.md + implementation_plan.json
+4. Spawn `spec_validation` → verifies completeness
+5. Done
+
+#### COMPLEX Tasks
+1. Spawn `spec_discovery` → receives context.json
+2. Spawn `spec_gatherer` → receives requirements.json
+3. If `needs_research`: Spawn `spec_researcher` → receives research.json
+4. Spawn `spec_writer` with all accumulated context
+5. Spawn `spec_critic` → reviews for gaps
+6. If critic finds issues: fix them yourself or re-spawn `spec_writer` with critique
+7. Spawn `spec_validation` → final check
+8. Done
+
+### Phase 3: Verify Outputs
+
+Before finishing, verify these files exist in the spec directory:
+- `spec.md` — The specification document
+- `implementation_plan.json` — Valid JSON with `phases[].subtasks[]` structure
+- `complexity_assessment.json` — The complexity assessment
+
+Read each file to confirm it's non-empty and well-formed.
+
+---
+
+## CONTEXT PASSING STRATEGY
+
+Each subagent starts fresh. You must pass them ALL relevant context:
+
+1. **Always include** the task description and spec directory path
+2. **Pass forward** outputs from prior subagents (the text/JSON they produced)
+3. **Keep context concise** — summarize prior outputs if they're very long (>10KB)
+4. **Include the project index** when available (helps subagents understand the codebase)
+
+Example of good context passing:
+```
+SpawnSubagent({
+  agent_type: "spec_writer",
+  task: "Write spec.md and implementation_plan.json for: [task]",
+  context: "Project: [dir]\nSpec dir: [specDir]\n\nRequirements (from discovery):\n[requirements.json content]\n\nProject context:\n[context.json content]\n\nResearch findings:\n[research.json content]",
+  expect_structured_output: false
+})
+```
+
+---
+
+## ADAPTIVE BEHAVIOR
+
+### When a subagent fails
+- Read the error or empty result
+- Decide if it's worth retrying with better instructions
+- Maximum 2 retries per subagent
+- If a subagent consistently fails, handle that step yourself using your own tools
+
+### When results are unexpected
+- If complexity_assessor returns low confidence (<0.6), default to STANDARD
+- If spec_writer misses files, check which ones and write them yourself
+- If spec_critic finds critical issues, address them before proceeding
+
+### When to skip subagents
+- SIMPLE tasks: write spec.md and implementation_plan.json yourself instead of spawning spec_writer
+- If project index gives you enough context, skip spec_discovery
+- If the task is well-defined with no external deps, skip spec_researcher
+
+---
+
+## IMPLEMENTATION PLAN SCHEMA
+
+The `implementation_plan.json` MUST follow this structure:
+
+```json
+{
+  "feature": "[task name]",
+  "workflow_type": "[feature|refactor|investigation|migration|simple]",
+  "phases": [
+    {
+      "id": "1",
+      "name": "Phase Name",
+      "subtasks": [
+        {
+          "id": "1-1",
+          "title": "Short title",
+          "description": "What to implement",
+          "status": "pending",
+          "files_to_create": ["new/file.ts"],
+          "files_to_modify": ["existing/file.ts"]
+        }
+      ]
+    }
+  ]
+}
+```
+
+**Schema rules:**
+- Top-level MUST have `phases` array
+- Each phase MUST have `subtasks` array with at least one subtask
+- Each subtask MUST have `id` (string) and `description` (string)
+- Status should be "pending" for all subtasks
+
+---
+
+## CRITICAL RULES
+
+1. **ALWAYS produce spec.md and implementation_plan.json** — These are required outputs
+2. **Pass context forward** — Each subagent needs accumulated context from prior steps
+3. **Verify before finishing** — Read back output files to confirm they exist and are valid
+4. **Be adaptive** — If a subagent fails or returns poor results, handle it yourself
+5. **Don't over-engineer simple tasks** — SIMPLE = write it yourself, don't spawn 5 subagents
+6. **Write paths are restricted** — You and subagents can only write to the spec directory
+
+---
+
+## BEGIN
+
+1. Read the task description from your kickoff message
+2. Assess complexity (self-assess or delegate)
+3. Route to the appropriate workflow
+4. Drive subagents through the pipeline

+## YOUR ROLE - QUICK SPEC AGENT
+
+You are the **Quick Spec Agent** for simple tasks in the Auto-Build framework. Your job is to create a minimal, focused specification for straightforward changes that don't require extensive research or planning.
+
+**Key Principle**: Be concise. Simple tasks need simple specs. Don't over-engineer.
+
+---
+
+## YOUR CONTRACT
+
+**Input**: Task description (simple change like UI tweak, text update, style fix)
+
+**Outputs** (write to the spec directory using the Write tool):
+- `spec.md` - Minimal specification (just essential sections)
+- `implementation_plan.json` - Simple plan using the **exact schema** below
+
+**This is a SIMPLE task** - no research needed, no extensive analysis required.
+
+**CRITICAL BOUNDARIES**:
+- You may READ any project file to understand the codebase
+- You may only WRITE files inside the spec directory (the directory containing your output files)
+- Do NOT create, edit, or modify any project source code, configuration files, or git state
+- Do NOT run shell commands — you do not have Bash access
+
+---
+
+## PHASE 1: UNDERSTAND THE TASK
+
+Review the task description and project index provided in your kickoff message. For simple tasks, you typically need to:
+1. Identify the file(s) to modify (use the project index to find them)
+2. Read only the specific file(s) you need to understand the change
+3. Know how to verify it works
+
+That's it. No deep analysis needed. **Do NOT scan the entire project** — the project index already tells you the structure.
+
+---
+
+## PHASE 2: CREATE MINIMAL SPEC
+
+Use the **Write tool** to create `spec.md` in the spec directory:
+
+```markdown
+# Quick Spec: [Task Name]
+
+## Task
+[One sentence description]
+
+## Files to Modify
+- `[path/to/file]` - [what to change]
+
+## Change Details
+[Brief description of the change - a few sentences max]
+
+## Verification
+- [ ] [How to verify the change works]
+
+## Notes
+[Any gotchas or considerations - optional]
+```
+
+**Keep it short!** A simple spec should be 20-50 lines, not 200+.
+
+---
+
+## PHASE 3: CREATE IMPLEMENTATION PLAN
+
+Use the **Write tool** to create `implementation_plan.json` in the spec directory.
+
+**IMPORTANT: You MUST use this exact JSON structure with `phases` containing `subtasks`:**
+
+```json
+{
+  "feature": "[task name]",
+  "workflow_type": "simple",
+  "phases": [
+    {
+      "id": "1",
+      "phase": 1,
+      "name": "Implementation",
+      "depends_on": [],
+      "subtasks": [
+        {
+          "id": "1-1",
+          "title": "[Short 3-10 word summary]",
+          "description": "[Detailed implementation notes - optional]",
+          "status": "pending",
+          "files_to_create": [],
+          "files_to_modify": ["[path/to/file]"],
+          "verification": {
+            "type": "manual",
+            "run": "[verification step]"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+**Schema rules:**
+- Top-level MUST have a `phases` array (NOT `steps`, `tasks`, or `implementation_steps`)
+- Each phase MUST have a `subtasks` array (NOT `steps` or `tasks`)
+- Each subtask MUST have `id` (string) and `title` (string, short 3-10 word summary)
+- Each subtask SHOULD have `description` (detailed notes), `status` (default: "pending"), `files_to_modify`, and `verification`
+
+---
+
+## PHASE 4: VERIFY
+
+Read back both files to confirm they were written correctly.
+
+---
+
+## COMPLETION
+
+After writing both files, output:
+
+```
+=== QUICK SPEC COMPLETE ===
+
+Task: [description]
+Files: [count] file(s) to modify
+Complexity: SIMPLE
+
+Ready for implementation.
+```
+
+---
+
+## CRITICAL RULES
+
+1. **USE WRITE TOOL** - Create files using the Write tool, NOT shell commands
+2. **KEEP IT SIMPLE** - No research, no deep analysis, no extensive planning
+3. **BE CONCISE** - Short spec, simple plan, one subtask if possible
+4. **USE EXACT SCHEMA** - The implementation_plan.json MUST use `phases[].subtasks[]` structure
+5. **DON'T OVER-ENGINEER** - This is a simple task, treat it simply
+6. **DON'T READ EVERYTHING** - Only read the specific files needed for the change
+
+---
+
+## EXAMPLES
+
+### Example 1: Button Color Change
+
+**Task**: "Change the primary button color from blue to green"
+

+ * 2. Analyze semantic changes from each task
+ * 3. Detect conflicts between tasks
+ * 4. Apply deterministic merges where possible (AutoMerger)
+ * 5. Call AI resolver for ambiguous conflicts (merge-resolver.ts)
+ * 6. Produce final merged content and detailed report

+/**
+ * Parallel Orchestrator PR Reviewer
+ * ==================================
+ *
+ * PR reviewer using parallel specialist analysis via Promise.allSettled().
+ * See apps/desktop/src/main/ai/runners/github/parallel-orchestrator.ts for the TypeScript implementation.
+ *
+ * The orchestrator analyzes the PR and runs specialized agents (security,
+ * quality, logic, codebase-fit) in parallel. Results are synthesized into
+ * a final verdict.
+ *
+ * Key Design:
+ * - Replaces SDK `agents={}` with Promise.allSettled() pattern
+ * - Each specialist loads a rich .md system prompt from apps/desktop/prompts/github/
+ * - Specialists get Read/Grep/Glob tool access via the agent config registry
+ * - Cross-validation: findings flagged by multiple specialists get boosted severity
+ * - Finding-validator pass: re-reads actual code to confirm/dismiss each finding
+ * - Uses createSimpleClient() for lightweight parallel sessions

+
+**You have Read, Grep, and Glob tools available. You MUST use them.**
+
+Before producing your final JSON output, you MUST complete these steps:
+
+1. **Read each changed file** — Use the Read tool to examine the full context of every changed file listed above (not just the diff). Read at least 50 lines around each changed section to understand the broader context.
+
+2. **Grep for patterns** — Use Grep to search for related patterns across the codebase:
+   - Search for callers/consumers of changed functions
+   - Search for similar patterns that might be affected
+   - Verify claims about "missing" protections by searching for them
+
+3. **Verify before concluding** — If you find zero issues, you must still demonstrate that you examined the code thoroughly. Your summary should reference specific files and lines you examined.
+
+**If your response contains zero tool calls, your review will be considered invalid.** A thorough review requires reading actual source code, not just reviewing diffs.`;

+
+1. **Security** - Look for vulnerabilities, injection risks, authentication issues
+2. **Quality** - Check for bugs, error handling, edge cases
+3. **Style** - Consistent naming, formatting, best practices
+4. **Tests** - Are changes tested? Test coverage concerns?
+5. **Performance** - Potential performance issues, inefficient algorithms
+6. **Documentation** - Are changes documented? Comments where needed?
+
+## Output Format
+
+Provide your review in the following JSON format (no markdown fencing):
+
+{
+  "summary": "Brief overall assessment of the MR",
+  "verdict": "ready_to_merge|merge_with_changes|needs_revision|blocked",

+
+- Be specific about file and line numbers
+- Provide actionable suggestions
+- Don't flag style issues that are project conventions
+- Focus on real issues, not nitpicks

+ *
+ * Architecture:
+ * - `runContinuableSession()` loops over `runAgentSession()` calls
+ * - On `context_window` outcome: compact messages → inject summary → re-run
+ * - On any other outcome: return merged result
+ * - `maxContinuations` (default 5) prevents infinite loops
+ *
+ * The orchestration layer (`BuildOrchestrator`, `QALoop`) doesn't know about

+
+Key Principle: Read the error, understand the schema, fix the file. Be surgical.
+
+Schemas:
+- context.json requires: task_description (string)
+- implementation_plan.json requires: feature (string), workflow_type (string: feature|refactor|investigation|migration|simple|bugfix), phases (array of {phase|id, name, subtasks})
+- Each subtask requires: id (string), description (string), status (string: pending|in_progress|completed|blocked|failed)
+- spec.md requires sections: ## Overview, ## Workflow Type, ## Task Scope, ## Success Criteria
+
+Rules:
+1. READ BEFORE FIXING - Always read the file first
+2. MINIMAL CHANGES - Only fix what's broken, don't restructure
+3. PRESERVE DATA - Don't lose existing valid data
+4. VALID OUTPUT - Ensure fixed file is valid JSON/Markdown
+5. ONE FIX AT A TIME - Fix one error, verify, then next`;

+# ProjectSettings Refactoring
+
+This directory contains the refactored components from the original 1,445-line `ProjectSettings.tsx` file. The refactoring improves code maintainability, reusability, and testability by breaking down the monolithic component into smaller, focused modules.
+
+## Architecture Overview
+
+### Original Structure
+- **Single file**: 1,445 lines
+- **Multiple concerns**: State management, UI rendering, API calls, and business logic all mixed
+- **Hard to maintain**: Complex component with many responsibilities
+- **Difficult to test**: Tightly coupled logic
+
+### New Structure
+- **Modular approach**: Split into 17+ files
+- **Separation of concerns**: Custom hooks, section components, and utility components
+- **Easier to maintain**: Each file has a single, clear responsibility
+- **Testable**: Individual components and hooks can be tested in isolation
+
+## Directory Structure

+
+## Main Component (ProjectSettings.tsx)
+
+The refactored main component is now only **~320 lines** (down from 1,445), focusing on:
+- Orchestrating child components
+- Managing dialog state
+- Coordinating save operations
+- Handling component composition
+
+## Benefits of This Refactoring
+
+1. **Maintainability**: Each file has a clear, single responsibility
+2. **Reusability**: Utility components can be used in other parts of the app
+3. **Testability**: Individual components and hooks can be tested in isolation
+4. **Readability**: Smaller files are easier to understand
+5. **Type Safety**: Explicit prop interfaces improve TypeScript coverage
+6. **Performance**: Can optimize individual components without affecting others
+7. **Collaboration**: Multiple developers can work on different sections simultaneously
+
+## Migration Guide
+
+The refactored component maintains the same external API:
+
+```tsx
+// Usage remains the same
+<ProjectSettings
+  project={project}
+  open={isOpen}
+  onOpenChange={setIsOpen}
+/>
+```
+
+All functionality is preserved - this is a pure refactor with no breaking changes.
+
+## Future Improvements
+
+Potential enhancements for the future:
+1. Add unit tests for each component and hook
+2. Add Storybook stories for visual testing
+3. Extract common patterns into additional shared components
+4. Add error boundary components
+5. Implement optimistic updates for better UX
+6. Add analytics tracking for user interactions

-**Windows:**
-```bash
-winget install OpenJS.NodeJS.LTS
-```
-
-**macOS:**
-```bash
-brew install node@24
-```
-
-**Linux (Ubuntu/Debian):**
-```bash
-curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -

-
-**Verify installation:**
-```bash
-node --version  # Should output: v24.12.0
-npm --version   # Should output: 11.x.x or higher
-```
-
-> **Note:** npm is included with Node.js. If `npm` is not found after installing Node.js, you need to reinstall Node.js properly.
-

-
-## Development Guidelines
-
-### Code Organization Principles
-
-1. **Feature-based Architecture**: Group related code by feature, not by type
-2. **Single Responsibility**: Each component/hook/store does one thing well
-3. **DRY (Don't Repeat Yourself)**: Extract reusable logic into shared modules
-4. **KISS (Keep It Simple)**: Prefer simple solutions over complex ones
-5. **SOLID Principles**: Apply object-oriented design principles
-
-### Naming Conventions
-
-| Type | Convention | Example |
-|------|------------|---------|
-| Components | PascalCase | `TaskCard.tsx` |
-| Hooks | camelCase with `use` prefix | `useTaskStore.ts` |
-| Stores | kebab-case with `-store` suffix | `task-store.ts` |
-| Types | PascalCase | `Task`, `TaskStatus` |
-| Constants | SCREAMING_SNAKE_CASE | `MAX_RETRIES` |
-
-### TypeScript Guidelines
-
-- **No implicit `any`**: Always type your variables and parameters
-- **Use `type` for simple objects**: Prefer `type` over `interface`
-- **Export types separately**: Use `export type` for type-only exports
-
-### Security Guidelines
-
-- **Never expose secrets**: API keys, tokens should stay in main process
-- **Validate IPC data**: Always validate data coming through IPC
-- **Use contextBridge**: Never expose Node.js APIs directly to renderer
-
-## Troubleshooting
-
-### npm not found
-
-If `npm` command is not recognized after installing Node.js:
-
-1. **Windows**: Reinstall Node.js from https://nodejs.org and ensure you check "Add to PATH"
-2. **macOS/Linux**: Add to your shell profile:
-   ```bash
-   export PATH="/usr/local/bin:$PATH"
-   ```
-3. Restart your terminal
-
-### Native module errors
-
-If you get errors about native modules (node-pty, etc.):
-
-```bash
-npm run rebuild
-```
-
-### Windows build tools required
-
-If electron-rebuild fails on Windows, install Visual Studio Build Tools:
-
-1. Download from https://visualstudio.microsoft.com/visual-cpp-build-tools/
-2. Select "Desktop development with C++" workload
-3. Restart terminal and run `npm install` again
-
-## Git Hooks
-
-This project uses Husky for Git hooks that run automatically:
-
-### Pre-commit Hook
-
-Runs before each commit:
-- **lint-staged**: Lints staged `.ts`/`.tsx` files
-- **typecheck**: TypeScript type checking
-- **lint**: ESLint checks
-- **npm audit**: Security vulnerability check (high severity)
-
-### Commit Message Format
-
-We use [Conventional Commits](https://www.conventionalcommits.org/). Your commit messages must follow this format:
-
-```
-type(scope): description
-```
-
-**Valid types:**
-| Type | Description |
-|------|-------------|
-| `feat` | A new feature |
-| `fix` | A bug fix |
-| `docs` | Documentation changes |
-| `style` | Code style (formatting, semicolons, etc.) |
-| `refactor` | Code refactoring (no feature/fix) |
-| `perf` | Performance improvements |
-| `test` | Adding or updating tests |
-| `build` | Build system or dependencies |
-| `ci` | CI/CD configuration |
-| `chore` | Maintenance tasks |
-| `revert` | Reverting a previous commit |
-
-**Examples:**
-```bash
-git commit -m "feat(tasks): add drag and drop support"
-git commit -m "fix(terminal): resolve scroll position issue"
-git commit -m "docs: update README with setup instructions"
-git commit -m "chore: update dependencies"
-```
-
-## Package Manager
-
-This project uses **npm** (not pnpm or yarn). The lock files for other package managers are ignored.

- *
- * Profile IDs are generated by generateProfileId() in profile-utils.ts:
- * - 'default' for the default profile
- * - Sanitized profile names: name.toLowerCase().replace(/[^a-z0-9]+/g, '-')
- *   Examples: "Work" -> "work", "My Profile" -> "my-profile"
- *
- * The pattern matches:
- * - 'claude-login-' prefix
- * - Profile ID: lowercase letters, numbers, and hyphens (non-greedy to stop at timestamp)
- * - '-' separator before timestamp
- * - Timestamp: 13+ digit Unix timestamp

- * AgentProfileSelector - Reusable component for selecting agent profile in forms
- *
- * Provides a dropdown for quick profile selection (Auto, Complex, Balanced, Quick)
- * with an inline "Custom" option that reveals model and thinking level selects.
- * The "Auto" profile shows per-phase model configuration.
- *
- * Used in TaskCreationWizard and TaskEditDialog.

-# ProjectSettings Refactoring
-
-This directory contains the refactored components from the original 1,445-line `ProjectSettings.tsx` file. The refactoring improves code maintainability, reusability, and testability by breaking down the monolithic component into smaller, focused modules.
-
-## Architecture Overview
-
-### Original Structure
-- **Single file**: 1,445 lines
-- **Multiple concerns**: State management, UI rendering, API calls, and business logic all mixed
-- **Hard to maintain**: Complex component with many responsibilities
-- **Difficult to test**: Tightly coupled logic
-
-### New Structure
-- **Modular approach**: Split into 17+ files
-- **Separation of concerns**: Custom hooks, section components, and utility components
-- **Easier to maintain**: Each file has a single, clear responsibility
-- **Testable**: Individual components and hooks can be tested in isolation
-

-## Main Component (ProjectSettings.tsx)
-
-The refactored main component is now only **~320 lines** (down from 1,445), focusing on:
-- Orchestrating child components
-- Managing dialog state
-- Coordinating save operations
-- Handling component composition
-
-## Benefits of This Refactoring
-
-1. **Maintainability**: Each file has a clear, single responsibility
-2. **Reusability**: Utility components can be used in other parts of the app
-3. **Testability**: Individual components and hooks can be tested in isolation
-4. **Readability**: Smaller files are easier to understand
-5. **Type Safety**: Explicit prop interfaces improve TypeScript coverage
-6. **Performance**: Can optimize individual components without affecting others
-7. **Collaboration**: Multiple developers can work on different sections simultaneously
-
-## Migration Guide
-
-The refactored component maintains the same external API:
-
-```tsx
-// Usage remains the same
-<ProjectSettings
-  project={project}
-  open={isOpen}
-  onOpenChange={setIsOpen}
-/>
-```
-
-All functionality is preserved - this is a pure refactor with no breaking changes.
-
-## Future Improvements
-
-Potential enhancements for the future:
-1. Add unit tests for each component and hook
-2. Add Storybook stories for visual testing
-3. Extract common patterns into additional shared components
-4. Add error boundary components
-5. Implement optimistic updates for better UX
-6. Add analytics tracking for user interactions

-# Auto Claude CLI Usage
+# Auto Claude
 
-This document covers terminal-only usage of Auto Claude. **For most users, we recommend using the [Desktop UI](#) instead** - it provides a better experience with visual task management, progress tracking, and automatic Python environment setup.
+Auto Claude is a desktop application. All functionality is accessed through the Electron desktop UI.
 
-## When to Use CLI
+## Getting Started
 
-- You prefer terminal workflows
-- You're running on a headless server
-- You're integrating Auto Claude into scripts or CI/CD
+1. Download the latest release for your platform from the [Releases page](https://github.com/AndyMik90/Auto-Claude/releases)
+2. Install and launch the application
+3. Open your project (a git repository folder)
+4. Connect Claude via the OAuth setup guide in the app
+5. Create a task and let the agents work
 
-## Prerequisites
-
-- Python 3.9+
-- Claude Code CLI (`npm install -g @anthropic-ai/claude-code`)
-
-### Installing Python
-
-**Windows:**
-```bash
-winget install Python.Python.3.12
-```
-
-**macOS:**
-```bash
-brew install python@3.12
-```
-
-**Linux (Ubuntu/Debian):**
-```bash
-sudo apt install python3.12 python3.12-venv
-```
-
-**Linux (Fedora):**
-```bash
-sudo dnf install python3.12
-```
-
-## Setup
-
-**Step 1:** Navigate to the backend directory
-
-```bash
-cd apps/backend
-```
-
-**Step 2:** Set up Python environment
-
-```bash
-# Using uv (recommended)
-uv venv && uv pip install -r requirements.txt
-
-# Or using standard Python
-python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt
-```
-
-**Step 3:** Configure environment
+## Running the App from Source
 
 ```bash
-cp .env.example .env
+# Install dependencies
+npm run install:all
 
-# Get your OAuth token
-claude setup-token
+# Development mode (hot reload)
+npm run dev
 
-# Add the token to apps/backend/.env
-# CLAUDE_CODE_OAUTH_TOKEN=your-token-here
+# Production build + run
+npm start
 ```
 
-## Creating Specs
-
-All commands below should be run from the `apps/backend/` directory:
-
-```bash
-# Activate the virtual environment (if not already active)
-source .venv/bin/activate
-
-# Create a spec interactively
-python runners/spec_runner.py --interactive
-
-# Or with a task description
-python runners/spec_runner.py --task "Add user authentication with OAuth"
-
-# Force a specific complexity level
-python runners/spec_runner.py --task "Fix button color" --complexity simple
-
-# Continue an interrupted spec
-python runners/spec_runner.py --continue 001-feature
-```
-
-### Complexity Tiers
-
-The spec runner automatically assesses task complexity:
-
-| Tier | Phases | When Used |
-|------|--------|-----------|
-| **SIMPLE** | 3 | 1-2 files, single service, no integrations (UI fixes, text changes) |
-| **STANDARD** | 6 | 3-10 files, 1-2 services, minimal integrations (features, bug fixes) |
-| **COMPLEX** | 8 | 10+ files, multiple services, external integrations |
-
-## Running Builds
-
-```bash
-# List all specs and their status
-python run.py --list
-
-# Run a specific spec
-python run.py --spec 001
-python run.py --spec 001-feature-name
-
-# Limit iterations for testing
-python run.py --spec 001 --max-iterations 5
-```
-
-## QA Validation
-
-After all chunks are complete, QA validation runs automatically:
-
-```bash
-# Skip automatic QA
-python run.py --spec 001 --skip-qa
-
-# Run QA validation manually
-python run.py --spec 001 --qa
-
-# Check QA status
-python run.py --spec 001 --qa-status
-```
-
-The QA validation loop:
-1. **QA Reviewer** checks all acceptance criteria
-2. If issues found → creates `QA_FIX_REQUEST.md`
-3. **QA Fixer** applies fixes
-4. Loop repeats until approved (up to 50 iterations)
-
-## Workspace Management
-
-Auto Claude uses Git worktrees for isolated builds:
-
-```bash
-# Test the feature in the isolated workspace
-cd .worktrees/auto-claude/
-npm run dev  # or your project's run command
-
-# Return to backend directory to run management commands
-cd apps/backend
-
-# See what was changed
-python run.py --spec 001 --review
-
-# Merge changes into your project
-python run.py --spec 001 --merge
-
-# Discard if you don't like it
-python run.py --spec 001 --discard
-```
-
-## Interactive Controls
-
-While the agent is running:
-
-```bash
-# Pause and add instructions
-Ctrl+C (once)
-
-# Exit immediately
-Ctrl+C (twice)
-```
-
-**File-based alternative:**
-```bash
-# Create PAUSE file to pause after current session
-touch specs/001-name/PAUSE
-
-# Add instructions
-echo "Focus on fixing the login bug first" > specs/001-name/HUMAN_INPUT.md
-```
-
-## Spec Validation
-
-```bash
-python validate_spec.py --spec-dir specs/001-feature --checkpoint all
-```
-

 # Windows Development Guide
 
-This guide covers Windows-specific considerations when developing
-Auto Claude.
+This guide covers Windows-specific considerations when developing Auto Claude.
 
-## File Encoding
+## Setup
 
-### Problem
+Auto Claude downloads prebuilt native binaries for `node-pty` on Windows automatically. If prebuilts are not available for your Electron version, you will need Visual Studio Build Tools:
 
-Windows Python defaults to the `cp1252` (Windows-1252) code page instead
-of UTF-8. This causes encoding errors when reading/writing files with
-non-ASCII characters.
-
-**Common Error:**
-
-```plaintext
-UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 1234
-```
-
-### Solution
-
-**Always specify `encoding="utf-8"` for all text file operations.**
-
-See [CONTRIBUTING.md - File Encoding](../CONTRIBUTING.md#file-encoding-python)
-for detailed examples and patterns.
-
-### Testing on Windows
-
-To verify your code works on Windows:
-
-1. **Test with non-ASCII content:**
-
-   ```python
-   # Include emoji, international chars in test data
-   test_data = {"message": "Test 🚀 with ñoño and 中文"}
-   ```
-
-2. **Run pre-commit hooks:**
-
-   ```bash
-   pre-commit run check-file-encoding --all-files
-   ```
-
-3. **Run all tests:**
-
-   ```bash
-   npm run test:backend
-   ```
-
-### Common Pitfalls
-
-#### Pitfall 1: JSON files
-
-```python
-# Wrong - no encoding
-with open("config.json") as f:
-    data = json.load(f)
-
-# Correct
-with open("config.json", encoding="utf-8") as f:
-    data = json.load(f)
-```
-
-#### Pitfall 2: Path methods
-
-```python
-# Wrong
-content = Path("README.md").read_text()
-
-# Correct
-content = Path("README.md").read_text(encoding="utf-8")
-```
-
-#### Pitfall 3: Subprocess output
-
-```python
-# Wrong
-result = subprocess.run(cmd, capture_output=True, text=True)
-
-# Correct
-result = subprocess.run(cmd, capture_output=True, encoding="utf-8")
-```
+1. Download [Visual Studio Build Tools 2022](https://visualstudio.microsoft.com/visual-cpp-build-tools/)
+2. Select the "Desktop development with C++" workload
+3. In "Individual Components", add "MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs"
+4. Restart your terminal and run `npm install` again inside `apps/desktop/`
 
 ## Line Endings
 
-### Problem
-
-Windows uses CRLF (`\r\n`) line endings while macOS/Linux use LF (`\n`).
-This can cause git diffs to show every line as changed.
-
-### Solution
-
-1. **Configure git to handle line endings:**
-
-   ```bash
-   git config --global core.autocrlf true
-   ```
-
-2. **The project's `.gitattributes` handles this automatically:**
+Windows uses CRLF (`\r\n`) line endings while macOS/Linux use LF (`\n`). This can cause git diffs to show every line changed.
 
-   ```plaintext
-   * text=auto
-   *.py text eol=lf
-   *.md text eol=lf
-   ```
+Configure git to handle line endings:
 
-3. **In code, normalize when processing:**
+```bash
+git config --global core.autocrlf true
+```
 
-   ```python
-   # Normalize line endings to LF (idiomatic approach)
-   content = "\n".join(content.splitlines())
-   ```
+The project's `.gitattributes` handles this automatically for tracked files.
 
 ## Path Separators
 
-### Problem
-
-Windows uses backslash `\` for paths, while Unix uses `/`.
-This can break path operations.
-
-### Solution
-
-1. **Always use `Path` from `pathlib`:**
-
-   ```python
-   from pathlib import Path
-
-   # Correct - works on all platforms
-   config_path = Path("config") / "settings.json"
-
-   # Wrong - Unix only
-   config_path = "config/settings.json"
-   ```
-
-2. **Use `os.path.join()` for strings:**
-
-   ```python
-   import os
-
-   # Correct
-   config_path = os.path.join("config", "settings.json")
-   ```
-
-3. **Never hardcode separators:**
-
-   ```python
-   # Wrong - Unix only
-   path = "apps/backend/core"
-
-   # Correct
-   path = os.path.join("apps", "backend", "core")
-   # Or better
-   path = Path("apps") / "backend" / "core"
-   ```
+TypeScript code should use `path.join()` or `path.posix.join()` rather than hardcoded forward or back slashes. The platform abstraction layer in `apps/desktop/src/main/platform/` provides cross-platform helpers — always use those instead of `process.platform` directly.
 
 ## Shell Commands
 
-### Problem
-
-Windows doesn't have bash by default. Shell commands need to work across
-platforms.
-
-### Solution
-
-1. **Use Python libraries instead of shell:**
-
-   ```python
-   # Instead of shell commands
-   import shutil
-   shutil.copy("source.txt", "dest.txt")  # Instead of cp
-
-   import os
-   os.remove("file.txt")  # Instead of rm
-   ```
-
-2. **Use `shlex` for cross-platform commands:**
-
-   ```python
-   import shlex
-   import subprocess
-
-   cmd = shlex.split("git rev-parse HEAD")
-   result = subprocess.run(cmd, capture_output=True, encoding="utf-8")
-   ```
-
-3. **Check platform when needed:**
-
-   ```python
-   import sys
-
-   if sys.platform == "win32":
-       # Windows-specific code
-       pass
-   else:
-       # Unix code
-       pass
-   ```
-
-## Development Environment
-
-### Recommended Setup on Windows
-
-1. **Use WSL2 (Windows Subsystem for Linux)** - Recommended:
-   - Most consistent with production Linux environment
-   - Full bash support
-   - Better performance for file I/O
-   - Install from Microsoft Store or: `wsl --install`
-
-2. **Or use Git Bash:**
-   - Comes with Git for Windows
-   - Provides Unix-like shell
-   - Lighter than WSL
-   - Download from [gitforwindows.org](https://gitforwindows.org/)
-
-3. **Or use PowerShell with Python:**
-   - Native Windows environment
-   - Requires extra care with paths/encoding
-   - Built into Windows
-
-### Editor Configuration
-
-**VS Code settings for Windows (`settings.json`):**
-
-```json
-{
-  "files.encoding": "utf8",
-  "files.eol": "\n",
-  "python.analysis.typeCheckingMode": "basic",
-  "editor.formatOnSave": true
-}
-```
-
-## Common Issues and Solutions
-
-### Issue: Permission errors when deleting files
-
-**Problem:** Windows file locking is stricter than Unix.
-
-**Solution:** Ensure files are properly closed using context managers:
-
-```python
-# Use context managers
-with open(path, encoding="utf-8") as f:
-    data = f.read()
-# File is closed here - safe to delete
-```
-
-### Issue: Long path names
-
-**Problem:** Windows has a 260-character path limit (legacy).
-
-**Solution:**
-
-1. Enable long paths in Windows 10+ (Group Policy or Registry)
-2. Or keep paths short
-3. Or use WSL2
-
-### Issue: Case-insensitive filesystem
-
-**Problem:** Windows filesystem is case-insensitive
-(`File.txt` == `file.txt`).
-
-**Solution:** Be consistent with casing in filenames and imports:
-
-```python
-# Consistent casing
-from apps.backend.core import Client  # File: client.py
-
-# Avoid mixing cases
-from apps.backend.core import client  # Could work on Windows but fail on Linux
-```
+The Bash tool in the AI agent layer validates commands against the allowlist defined in `apps/desktop/src/main/ai/security/`. On Windows, `.cmd` and `.bat` files require `shell: true` — the platform module's `requiresShell()` helper handles this automatically.
 
 ## Testing Windows Compatibility
 
-### Before Submitting a PR
+CI runs all three platforms (Ubuntu, Windows, macOS) on every PR. To test locally on Windows:
 
-1. **Run pre-commit hooks:**
+```bash
+cd apps/desktop
 
-   ```bash
-   pre-commit run --all-files
-   ```
+# Run unit tests
+npm test
 
-2. **Run all tests:**
+# Run type checking
+npm run typecheck
 
-   ```bash
-   npm run test:backend
-   npm test  # frontend tests
-   ```
+# Run linter
+npm run lint
+```
 
-3. **Test with special characters:**
+## Common Issues
 
-   ```python
-   # Add test data with emoji, international chars
-   test_content = "Test 🚀 ñoño 中文 العربية"
-   ```
+### Permission errors when deleting files
 
-### Windows-Specific Test Cases
+Windows file locking is stricter than Unix. Ensure streams and file handles are properly closed before attempting to delete or overwrite files.
 
-Add tests for Windows compatibility when relevant:
+### Long path names
 
-```python
-import sys
-import pytest
+Windows has a 260-character path limit by default. Enable long paths:
 
-@pytest.mark.skipif(sys.platform != "win32", reason="Windows only")
-def test_windows_encoding():
-    """Test Windows encoding with special characters."""
-    content = "Test 🚀 ñoño 中文"
-    Path("test.txt").write_text(content, encoding="utf-8")
-    loaded = Path("test.txt").read_text(encoding="utf-8")
-    assert loaded == content
-```
+1. Open Group Policy Editor (`gpedit.msc`)
+2. Navigate to: Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem
+3. Enable "Enable Win32 long paths"
 
-## Getting Help
+Or use WSL2 to avoid the issue entirely.
 
-If you encounter Windows-specific issues:
+### Case-insensitive filesystem
 
-1. Check this guide and [CONTRIBUTING.md](../CONTRIBUTING.md)
-2. Search [existing issues](https://github.com/AndyMik90/Auto-Claude/issues)
-3. Ask in [discussions](https://github.com/AndyMik90/Auto-Claude/discussions)
-4. Create an issue with `[Windows]` tag
+Windows filesystems are case-insensitive. Be consistent with casing in import paths — a mismatch that works on Windows will fail on Linux CI.

-The Claude Code CLI supports fast mode via:
-  - `/fast` toggle in interactive mode
-  - `"fastMode": true` in user settings (~/.claude/settings.json)
-
-The challenge: The Agent SDK passes `--setting-sources ""` by default,
-which disables loading of user/project/local settings. This means even
-if fastMode is in ~/.claude/settings.json, the CLI subprocess won't read it.
-
-This script tests different invocation methods to find one that works:
-  1. --settings file with fastMode (current approach)
-  2. --setting-sources user (load user settings where fastMode lives)
-  3. --setting-sources user,project + project .claude/settings.json
-  4. CLAUDE_CONFIG_DIR/settings.json with setting-sources user
-  5. Direct CLI invocation with various flags
-
-Usage:
-    cd apps/backend
-    .venv/bin/python ../../tests/test_fast_mode_invocations.py
-
-Requirements:
-    - Claude Code CLI installed
-    - Active Claude subscription with extra usage enabled
-    - Opus 4.6 model access

-- AsyncIteratorMock: Async iterator mock for receive_response
-- ReceiveResponseMock: Smart wrapper supporting both .set_messages() and .return_value
-- setup_qa_mocks(): Module-level mock setup
-- cleanup_qa_mocks(): Module-level cleanup
-- reset_qa_mocks(): Reset shared mocks to default state
-- get_mock_*(): Accessor functions for mock objects
-- Mock response creation helpers

-Tests for Model Resolution
-===========================
-
-Tests the model resolution functionality including:
-- resolve_model_id() function from phase_config
-- Environment variable overrides
-- Model shorthand to full ID mapping
-- Default model values in GitHub runner services
-
-This ensures custom model configurations (e.g., ANTHROPIC_DEFAULT_SONNET_MODEL)
-are properly respected instead of falling back to hardcoded values.
-
-Note: Some tests use source code inspection to avoid complex import dependencies
-while still verifying the critical implementation patterns that prevent regression
-of the hardcoded fallback bug (ACS-294).
