From 63b2694455305aaf90cef7343aaddfe132a85406 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Fri, 7 Aug 2026 20:45:31 +0300 Subject: [PATCH 01/78] refactor(agent): move session_db into tinyagents, keep only its RPC surface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The session store and run ledger were generic harness machinery living in OpenHuman. They are now `tinyagents::harness::session_store`; this side keeps only what is genuinely host-specific. What stays here: `agent/session_db/schemas.rs` — the controller schemas and handlers. The RPC envelope, `Config` resolution, and `RpcOutcome` shape are host concerns the runtime crate should not know about. What moves: `ops`, `store`, `types`, and the whole `run_ledger/` subtree (~4.5k lines). Their only coupling to this crate was `config.workspace_dir`, so the crate-side entry points take `&Path` and call sites pass that field. Call sites are rewritten to `tinyagents::harness::session_store::*` rather than kept alive behind re-export shims, so there is no indirection left suggesting the store still lives here. 29 files across `orchestration/`, `core/`, `web_chat/`, `hosted/`, and `progress_tracing/`. Two seams needed real handling rather than a path rewrite: - Tail-position returns in `agent_teams/ops.rs` and `workflow_runs/ops.rs` now wrap `Ok(...?)`, because `Result` does not coerce to `anyhow::Result` without a conversion point. - `ControlError` gains `From`; its `#[from] anyhow::Error` variant does not apply to a distinct error type, and without this every ledger call in `command_center/control.rs` would need its own `map_err`. Behavior is unchanged. The database path (`{workspace}/session_db/sessions.db`) is identical, so existing installs keep their history, and the `session_db` / `run_ledger` RPC namespaces are untouched. Verified: core lib compiles, 12689 lib tests pass, 420 orchestration tests pass. Two unrelated pre-existing failures were confirmed against an untouched baseline and are not from this change — a stack overflow in `cron::scheduler::tests` (reproduces identically on a clean stash) and an order-dependent flake in `tinyplace::manifest` (passes in isolation).

[`SessionTranscriptHistory`] is a thin handle over the free functions in +//! [`super::transcript`]. It holds no state beyond the transcript's identity, +//! so it is cheap to construct per turn and safe to share. +//! +//! # Why the trait's `thread_id` is not used for path resolution +//! +//! `ChatHistory` is keyed by `thread_id`, but a `session_raw` transcript is +//! keyed by its **stem** (`{unix_ts}_{agent_id}`, or `{parent_chain}__…` for a +//! sub-agent). These are deliberately different: several transcripts can share +//! one `_meta.thread_id` — every sub-agent spawned within a thread does — so +//! resolving a path from `thread_id` would be ambiguous and could interleave +//! two agents' histories into one file. +//! +//! The handle is therefore bound to one transcript at construction, and the +//! `thread_id` argument is accepted for trait conformance only.

Carries + `model`, `iteration`, `ts`, `reasoning_content` and the native `tool_calls`. + The projection reads **every** `DisplayItem::ToolCall` off + `turn_usage.tool_calls`, so losing it deletes the tool rows outright (each + following `role:"tool"` line then falls to the orphan branch), along with + `Reasoning`, `AssistantMessage.{model,iteration}` and `interim`. +- **`TranscriptMeta`'s cumulative fields** — `turn_count` plus the four + token/cost rollups `read_thread_usage_summary` reports. The turn path computes + these fresh each turn; the trait path can only re-read the file's existing + `_meta`, which would freeze them at the previous turn's values. + +A literal `Arc` write would therefore have failed S4's own exit +criterion while looking complete. The criterion wins: what landed is +`pub(crate) trait SessionHistory: ChatHistory`, declared in +`agent/harness/session/transcript_history.rs`, whose single `append_turn` method +forwards the same six arguments `append_transcript_turn` already takes. The +indirection is real, `ChatHistory` stays in the bound so S2/S3 are not orphaned, +and the on-disk bytes are unchanged by construction — +`append_turn_is_byte_identical_to_the_free_function` writes one turn both ways +and compares the files byte for byte. + +The **read** path stays on the concrete free functions by design, and this is +not deferred work. Both resume readers *discover* a path — by +`(workspace, session_raw_subdir, agent name)` or by `_meta.thread_id` — and +neither key is a stem, the only thing a handle can be bound to. Worse, +`ChatHistory::messages()` returns `Vec`, and converting back flattens +`Assistant.tool_calls` into plain text, which is exactly what +`bound_cached_transcript_messages`' TAURI-RUST-7 trailing strip inspects and +what native providers reject with `400 assistant message with 'tool_calls' must +be followed by tool messages`. `maybe_shadow_read_session_store` additionally +needs the whole `SessionTranscript`, `_meta` included, which the trait cannot +return. + +**Widening `ChatHistory` upstream is REJECTED, not deferred.** S0's rationale +notes this question has already been re-opened twice, so the finding is recorded +here to stop a third round: the crate's `Usage` has no `cost_usd` / +`context_window`; `TranscriptMeta` is a cumulative *file header*, not turn +provenance; and the per-message tool-failure `extra_metadata` that +`message_to_chat_message` drops is untouchable by any turn-level record.

A +dedicated-memory profile's sessions live in `session_raw-/`, so wiring the +handle into the turn path as-written would have silently cross-written profile +sessions into the shared profile's directory. `new_in_dir` takes the raw dir +explicitly and is what the turn path uses. + +Deliberately **not** relocated: `persisted_transcript_messages` and +`session_transcript_path` stay on `Agent`.

Recorded so a future audit +finds the decision rather than re-deriving it. + +#### Where "~400 LOC" came from, and why it is struck + +§4 Option A originally claimed it "Removes: ~400 LOC of parallel abstraction". +The figure has no derivation anywhere in this document or its parent, and it is +not achievable. Its arithmetic origin is recoverable: §2.1's in-scope table +totals **2,475** LOC at this document's base commit (`transcript.rs` 1,997 + +`turn_checkpoint.rs` 105 + `migration.rs` 373). Option B's "~2,100 host LOC" is +exactly 1,997 + 105. The residual is **373 ≈ "~400" = `migration.rs`** — which +§5 S1 and `docs/tinyagents-full-migration-plan/99-deletion-ledger.md:33` both +resolve as HOST-OWNED, no deletion. Under Option A the §2.1 table loses **zero** +lines. + +Every other candidate was checked and refuted: + +- **No host trait duplicates `ChatHistory`.** The only other match in `src/` is + a `MemorySource::ChatHistory` *enum variant* in `memory/remember.rs`. + `memory/store/memory_trait.rs` is the long-term semantic `Memory` trait — a + different concern with a different shape. +- **`ShortTermMemory`'s `trim` is an empty hook slot** + (`vendor/tinyagents/src/harness/memory/types.rs`), so there is no crate-side + policy for the host to be parallel to. The host side is 104 LOC of + provider-400 defences (`trim_history`, `bound_cached_transcript_messages`) + with no crate analogue — not duplicated, not deletable. +- **`agent/context/`'s reducer was already deleted under #4249**, before this + document was written (`context/manager.rs`: "Live history reduction/ + summarization moved to the tinyagents graph"). What remains is prompt + assembly + stats. + +#### The one genuine parallel abstraction, and why S4/S5 cannot remove it + +The #4249 JSONL↔store mirror **is** a second session-persistence implementation, +over crate `Store`/`AppendStore` rather than `ChatHistory`: `session_import/ +live.rs` (353), `Agent::maybe_shadow_read_session_store` / +`maybe_dual_write_session_store` (119), the `StoreRegistry` registration in +`agent/tinyagents/mod.rs`, two `AgentConfig` flags, and +`config/migrations/enable_session_shadow_reads.rs` — ~565 prod LOC. It is the +closest thing in the tree to "~400 LOC of parallel abstraction". + +It is out of scope here for two reasons. It is #4249's own 04.1/04.2 program, +gated on that issue's Phase-2 parity soak (#5396, which flipped +`session_shadow_reads` default-ON with a config migration); and its terminus — +serving reads from the store — points the opposite way from this branch's +non-negotiable zero-on-disk-change constraint. **It is also not S5's soak:** S5 +compares free-function reads against trait reads, an entirely different +comparison. Track it as a #4249 phase-3 item ("retire the JSONL↔store dual path +once the Phase-2 parity soak declares parity") with a deletion-ledger row naming +the six sites above. + ### S5 — Shadow soak, then remove the parallel path One release with both paths live and a read-side comparison logged on mismatch From a22f37e12ff4d2fb3aaa240938ad0176725badcd Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Sat, 8 Aug 2026 08:43:22 +0300 Subject: [PATCH 67/78] chore(docs): add deletion ledger for tinyagents migration Adds a ledger documenting files removed during the tinyagents full migration, providing a clear record of deletions for audit and rollback purposes.
