From v1.0.0 +onward the project follows SemVer normally: patch releases are +bug-fix-only, minor releases are backward-compatible additions, and +breaking changes require a major bump. + +## v2.5.2: The brain that learns from its own outcomes + +Consolidation v1: the first release where citation outcomes reshape the brain +itself, with every mechanism model-free and every constant documented on one +page. Backward-compatible (schema v9 → v10, automatic on open). + +### Consolidation v1 (new) + +- `kimetsu brain reinforce`: offline consolidation pass. `--staple` merges + memories that were repeatedly cited together into single fact memories + (precomputed multi-hop joins; originals kept; provenance carries part ids). + `--routes` builds a query-routing index from citation history: memories that + answered similar questions before get a bounded retrieval boost. +- `kimetsu brain cite` accepts repeated `--memory-id` (citing a GROUP — the + co-citation signal stapling consumes) and `--query` (linking citations to + the question they answered, feeding the routing index). +- Retrieval-time routing boost with a fixed per-retrieval budget, per-candidate + cap, minimum support, and power-law decay. + +### Learning-loop guardrails + +- The usefulness boost's relevance gain is capped: a heavily-cited memory can + win ties but can never outrank a genuinely more relevant one (fixes a + measured retrieval-flooding failure mode under sustained citation feedback). +- Cited-in-failure penalty now scales with citation history + (`-1.0 / (1 + prior citations / 3)`): a proven memory absorbs occasional + flaky-run hits; an unproven one takes the full penalty. +- All scoring constants (deltas, caps, envelopes, decay) now live in one + documented module, `scoring.rs`. + +### Quality of life + +- Schema-mismatch errors name the offending `project.toml` and hint at the + fix (project discovery climbs to the enclosing git root, so the file is + often far from where you ran the command). +- npm packages ship with provenance attestations (Sigstore): every published + package is publicly verifiable as built by CI from this repo. +- Internal: `project.rs` and the CLI `main.rs` split into focused modules. + +### Benchmarks + +- LoCoMo: 89.4% on the standard 1,540-question set (LLM-judged accuracy). +- Learning-curve harness validated: citation feedback never degrades + retrieval across repeated iterations, with a train/holdout split proving + generalization. + +## v2.5.0: Ship the brain to your team + +Flagships: retrieval level presets (`basic`/`flexible`/`deep`/`advanced`), +temporal validity and date-aware ingestion, fleet write-safety (concurrent +writers, per-event origin), convergent team sync (HLC replay + conflict +surfacing), Kimetsu Remote GA with per-user attribution, and shareable brain +packs (gzip + security-scrubbed export, merge/replace import from file or +URL). Docs site moved to kimetsu.dev. + +## v2.0.0: Never explore twice + +The biggest token sink is RE-EXPLORATION: the agent re-deriving what the brain +(or the repo) already knows. v2.0 attacks it from three flagship directions and +adds a pluggable storage tier. Backward-compatible: existing `project.toml` and +`brain.db` files upgrade in place (schema v3 → v6, automatic on open). + +### Flagship: Session warm-start (never re-establish your work) -## v0.7.2 — remove kimetsu-harbor-rs; first crates.io publish of the v0.7 line +ADDED + * **Episodic work-resume.** A new `work_episode` record (event-sourced, + schema v5) captures your working state at SessionEnd: the task, what you + did, what FAILED and why (dead-ends), open threads, and the working + hypothesis, scoped per-repo (one live episode per repo). `kimetsu resume` + prints it; `kimetsu checkpoint [note]` saves one manually. Distilled via + the cheap model when configured, else a rule-based summary (never blocks). + Episodes are LOCAL-ONLY and never sync/export. + * **Project digest.** `kimetsu brain digest [--refresh]` assembles a compact + (~400-token) digest: repo manifest + top-usefulness memories + current + focus, cached at `.kimetsu/digest.md` by content hash, refreshed on git/ + corpus drift. (The digest is currently rule-based; a cheap-model + distillation hook-point is present but not yet wired.) + * **SessionStart injection.** A new `kimetsu brain session-start-hook` emits + the digest + resume as `additionalContext`, gated by `[broker] warm_start` + (default on). Wired for Claude Code; other hosts' SessionStart context + surface is not yet verified and is intentionally left unwired. + +### Flagship: The active brain (never wait on the brain) + +ADDED + * **`kimetsu brain ask ""`.** Terminal Q&A answered entirely from + the brain: full retrieval + a grounded answer composed by a LOCAL/cheap + model, with memory-id citations. Zero frontier tokens; works offline. Falls + back to distiller credentials, then to verbatim top-capsules when no model + is configured. Grounded-only: refuses rather than hallucinating when memory + has no answer. `--json`; an answer marked helpful counts like a citation. + * **`kimetsu_brain_answer` MCP tool.** A read-only synthesis tool the host + agent can call mid-task ("what do we know about X?") for a grounded, cited + brief instead of re-discovering. + * **Command recall fast-path.** "How do I…" queries surface matching + `command`-kind memories runnable-line-first. + * **Answer-grade injection.** Very-high-confidence capsules (score ≥ + `[broker] answer_grade_min_score`, default 0.92) are prefixed "Verified + answer from project memory:" so the model can act in one turn. Render-time + only (ranking is untouched) and suppressed when the memory was recently a + floor-drop regret. + * **Proactive pre-fetch.** Opt-in `[broker] proactive_prefetch` (default off) + warms trajectory-relevant memories at PreToolUse. + +### Flagship: Memory → skill synthesis (never re-derive a solution) + +ADDED + * **Skill synthesis.** A memory cited ≥3 times (or a tight cluster) becomes a + synthesis candidate; `kimetsu brain skills [--review]` drafts an executable + skill from it (grounded strictly in the cited memories) and, on explicit + accept, installs it into the host-native skill dir with provenance back to + the source memory ids. Propose-only (never auto-installed); flagged stale + when a source memory is superseded. Schema v6 (`skill_proposals`). + +### Local-model independence + +ADDED + * **Ollama as a first-class provider** (`provider = "ollama"`, OpenAI-compat, + `localhost:11434/v1` default, no key) and a single optional `[cheap_model]` + config that all cheap-model consumers resolve (distiller, consolidation, + digest, resume, skill draft, `ask`). Back-compatible with + `[learning.distiller]`; OPTIONAL everywhere: every consumer degrades + gracefully when no model is configured. `kimetsu doctor` probes the local + endpoint. New guide: `docs/LOCAL-MODELS.md` (fully-local = zero external + calls). + +### Pluggable storage backends + +ADDED + * **`RetrievalBackend` trait** with `[storage] backend = "flat" | "graph-lite" + | "graph"` (default `flat`). The broker stays backend-agnostic; switching + backends re-projects from the event log. + * **Graph-lite (Tier 1)**: a typed-edge projection (`memory_edges`, schema + v4) with 1-2 hop expansion blended as graph-provenance candidates (a strict + superset of flat, no recall loss; the broker still filters). `supersedes` + edges populate now; episode-sourced edge types are reserved. + * **Petgraph (Tier 2, remote-only)** behind the `graph` feature (off in local + lean/embeddings builds, petgraph is never compiled there). In-memory graph + with centrality / shortest-path / community-detection helpers, plus a + cross-backend benchmark harness. Spike verdict: an embedded graph DB + (Kùzu/Cozo) is not justified through ~100k memories. + +### Continuous self-tuning + ROI v2 + +ADDED + * **Re-tune triggers** (≥50 new memories since last tune, or elevated regret + rate) surfaced via `kimetsu brain tune --status` + a Stop-hook one-liner, + proposed, never auto-applied. **Model re-selection advisor** + (`tune --models`) with reindex/download cost stated. **Regret-driven + objective**: the tune objective now penalizes floor configs that produced + regrets. **ROI v2**: per-memory ROI (`roi --top`), output-token accounting, + and warm-start (`digest_served`/`resume_served`) savings attribution. + +### Personal brain sync + +ADDED + * **Event-log replication** (not file copying). `kimetsu brain sync export + --since ` / `import` move durable memory-lifecycle events as + portable JSONL with per-event idempotency; telemetry, raw queries, and + local-only episodes are excluded by an allowlist; redaction is respected. + `[sync] dir` drives a server-less directory protocol (Dropbox/Syncthing/NAS) + with per-machine batches and per-source cursors; `--dry-run` and + `--status` throughout. Object-storage backends (e.g. S3) are deferred. + +### Hardening & release + +FIXED + * Analytics/doctor active counts, reindex, peek/undo, and `memory list` now + consistently exclude superseded rows; `config set`/`tune --apply` preserve + toml comments + unknown keys (`toml_edit`); dropped-capsule + proactive-state + sidecars write atomically. Cursor/Gemini MCP schemas verified against live + docs. + * **Release pipeline**: a `version-guard` job fails in seconds on a + tag/workspace-version mismatch (and the built binary must self-report the + tag): closing the gap that produced the v1.5.0 botch; core GitHub Actions + bumped to Node-24-ready versions; `scripts/bump-version.sh` codifies the + one-step version bump. + +KNOWN LIMITATIONS + * SessionStart warm-start is wired for Claude Code only; the digest is + rule-based pending the cheap-model distillation wiring; full retrieval- + quality and first-turn-token benchmarks require the embeddings + Docker + environment and were not run in CI; remote-bench process isolation (#23) + remains open. + +## v1.5.1: version-stamp re-release + +Identical feature set to v1.5.0. The v1.5.0 artifacts were built before the +workspace version bump, so their binaries self-report `1.0.0` (which also +broke the crates.io publish: `kimetsu-core@1.0.0` already existed). npm +forbids reusing a published version, so the corrected release ships as +v1.5.1. If you installed v1.5.0 from npm or the GitHub release, update. + +FIXED + * Workspace and inter-crate versions stamped correctly (`kimetsu --version` + now reports the release version; crates.io publish unblocked). + +## v1.5.0: pays for itself + +ADDED + * **Telemetry capture.** Raw query text is now stored in `context.served` + telemetry events when `[learning] store_queries = true` (default; set + `false` to revert to the pre-v1.5 query-hash-only behavior). A + `session_id` field is also written when the host provides one (Claude Code + hooks; absent for hosts that do not emit it). Dropped-capsule sidecar + (`~/.kimetsu/cache//dropped-recent.json`) records capsules that + were floor-filtered out so that a later citation of one is detected as a + `retrieval.regret` event, feeding the self-tuning loop. All telemetry + stays on-machine; nothing is exported. + + * **ROI ledger (`kimetsu brain roi`).** Conservative per-kind token-savings + estimates (failure_pattern=1500, command=400, convention=300, fact=500, + preference=200 tokens per citation) minus brain-injection overhead give a + net-positive / net-negative verdict. Dollar estimates are shown when the + active model is recognized from a built-in price table (Claude 3/4, GPT-4/5 + families, Bedrock routing prefixes) or when `[model] price_per_mtok` is set + in `project.toml`. `--window 7d|30d|all` and `--json` for scripting. The + Stop hook appends a per-session savings sentence when ≥1 citation occurred; + zero-citation sessions are silent. Calibration methodology and honest + limitations: `docs/ROI-METHODOLOGY.md`. + + * **Token budget: render-time capsule compression and session dedupe.** + Two `[broker]` toggles, both default `true`: + - `compress_capsules`: capsule summaries are compressed at render time + (strips `[tags: ...]` / `(context: ...)` annotations, caps at 3 + sentences). Ranking is never affected: this runs only after retrieval + and reranking. Set `false` to inject full memory text. + - `session_dedupe`: the `UserPromptSubmit` hook skips capsules whose + handle was already injected earlier in the same session (tracked via + the proactive-state sidecar). Soft policy: falls back to injecting all + capsules when dedupe would produce an empty set. This addresses the + pre-v1.5 behavior where the main hook re-injected the same top capsule + on every prompt of a long session. + + * **Self-Tuning Brain: `kimetsu_brain_cite` MCP tool + `kimetsu brain tune`.** + `kimetsu_brain_cite` is a new write-gated MCP tool that records a + `memory.cited` event from inside an MCP session, closing the ground-truth + gap when the model leans on a memory but doesn't explicitly call + `cite_memory`. Personal eval set: `tuneset` builds positive eval cases from + `context.served` + citation joins (exact session_id or ±30-minute window + fallback). `kimetsu brain tune --status` reports case count and kind + coverage. `kimetsu brain tune` (dry-run by default) sweeps `broker.min_lexical_coverage` + ∈ {0.3, 0.4, 0.5, 0.6} × `broker.min_semantic_score` ∈ {-1.0(AUTO), 0.0, 0.25, + 0.35, 0.45} against the production embedder; `--apply` writes only the + floor parameters (not the reranker; that change is recommended separately); + `--revert` restores the previous tune-history entry. A holdout guardrail + (deterministic 20% split) prevents writing a config that regresses the + holdout objective. + + * **Consolidation: `kimetsu brain consolidate` + `kimetsu brain triage`.** + Schema migrated to **v3** (`superseded_by` column + index on `memories`). + `brain consolidate` (Story 3.1, default): brute-force cosine scan within the + same embedding model; clusters at ≥ 0.92 cosine (configurable with + `--threshold`) are merged: survivor keeps its id and text, members get + `superseded_by` set and a `memory.superseded` event written (rebuild-safe); + citations are reassigned to the survivor. `--distill` (Story 3.2): looser + clusters (0.75-0.85 cosine band, ≥3 memories, ≥1 shared tag) are fed to + the configured distiller; result lands as a memory proposal for human + review; prints clusters and exits 0 when no distiller is configured. + `brain triage` (Story 3.3): interactive per-item keep / prune / skip of + memories below a usefulness and age threshold (`--score-floor 0.2`, + `--age-days 30`); `--prune-all --yes` for batch non-interactive pruning. + + * **Reach: export redact, Cursor + Gemini CLI installers, CI embeddings job.** + `kimetsu brain export --redact` strips the `(context: …)` segment from + exported memory text; `--redact-tags` (requires `--redact`) additionally + strips the `[tags: …]` prefix. Both flags are useful for sharing brains + without leaking workspace-specific file paths or tag metadata. + `kimetsu plugin install cursor` and `kimetsu plugin install gemini-cli` + write MCP config (`.cursor/mcp.json` / `.gemini/settings.json`) and an + always-on guidance file (`.cursor/rules/kimetsu-brain/rule.md` for workspace + installs; `GEMINI.md` merged into the project root or `~/.gemini/GEMINI.md` + for global installs). Neither host has a `UserPromptSubmit`-style hook + system, so MCP + the guidance file are the complete integration surface. + The Cursor and Gemini CLI config schemas match each host's current official + MCP documentation (Cursor: `mcpServers` with `type: "stdio"`; Gemini CLI: + `mcpServers` with transport inferred). CI: a new `test-embeddings` job (ubuntu-only, + `--features embeddings`, HuggingFace + fastembed cache) runs alongside the + existing lean test matrix. + +CHANGED + * `kimetsu.mcp_write_tools` gate now covers `kimetsu_brain_cite` alongside + the existing write tools (same env / config / default-true logic for the + local stdio server; remote server remains env-only, default-deny). + * Stop hook output includes a per-session token-savings line when the brain + was cited at least once that session. + * `brain.db` schema advanced from **v2 → v3** (automatic on first + read-write open; sidecar backup taken per the existing migration policy). + * `brain export` gains `--redact` / `--redact-tags` flags (no behavior + change for existing callers). + +FIXED + * Tune sweep now runs against the production embedder (not the Noop embedder + used in tests), so floor calibration is on real vectors. + +## v1.0.0: durable migrations, analytics, semantic retrieval, proactive recall + +ADDED + * **Remote cross-encoder rerank stage.** `kimetsu-remote serve` now applies a + cross-encoder reranker to every `kimetsu_brain_context` call (`--reranker`, + default `jina-reranker-v1-tiny-en`, operator-level; `"off"` disables; any + curated or HuggingFace ONNX id accepted). The default was chosen by the + 100-memory benchmark: jina-tiny MRR 0.931 vs 0.914 for TinyBERT on the local + bench; the remote path has no hook-latency budget so the fastest effective + reranker wins. Benchmark lift with reranker: jina-v2-base-code MRR 0.904 → + 0.906, bge-small MRR 0.901 → 0.909 (production floors active). + + * **Model-aware AUTO semantic floor + kimetsu-remote benchmark.** `kimetsu + brain bench --remote` boots a real kimetsu-remote server per embedder, + drives the 100-case dataset over HTTP MCP (sequential + concurrent), and + reports quality/latency/throughput/server-RSS. Its first run caught a + real bug: the 0.35 cosine floor (calibrated on bge) was KILLING relevant + jina-v2 results on every production path (remote MRR 0.90 -> 0.77). + `broker.min_semantic_score` now defaults to -1.0 = AUTO: 0.35 on + bge-family models, disabled elsewhere (jina-v2 own precision keeps noise + low); explicit values still win. Confirmed: jina-v2 remote recovered to + MRR 0.906 / recall@4 0.939 on the 100-memory corpus (with the server + reranker: ~416ms/request, ~5 rps at concurrency 4, ~1.2GB peak RSS). + * **Benchmark-chosen retrieval defaults: jina-v2-base-code + TinyBERT.** + `kimetsu brain bench` (100 real-memory cases) drove the defaults: + embedder `jina-v2-base-code` (recovers oblique queries bge-small never + pools; ~4x less off-topic noise) + reranker `ms-marco-tinybert-l-2-v2` + (~43ms, within noise of the best MRR). Existing brains need + `kimetsu brain reindex` after upgrading (vector dims 384 -> 768); set + `embedder.model`/`embedder.reranker` back to taste and re-judge with + `kimetsu brain bench`. Lean-RAM alternative: bge-small + tinybert. + * **Local MCP write tools enabled by default (`kimetsu.mcp_write_tools`).** + The brain's own workflow tells the agent to record lessons + (`kimetsu_brain_record`, the Stop-hook harvest cue), but the privileged- + write gate default-denied unless `KIMETSU_MCP_ENABLE_WRITE_TOOLS=1` was + in the MCP server's env, so every session ended with the agent goaded + into a blocked call. The gate is now config-driven for the LOCAL stdio + server: `kimetsu.mcp_write_tools` (default true), personalizable via + `kimetsu config set kimetsu.mcp_write_tools false`. Precedence: the env + var when set always wins (both directions) > config > default. The + REMOTE server is unchanged (env-only, default-deny) because a cloned + repo's project.toml is untrusted input and must never enable writes. + * **Cross-encoder reranking (opt-in) + retrieval eval harness + 300ms + hook budget.** The warm daemon can apply a final cross-encoder rerank + stage: over-fetch a 12-capsule pool, score each (query, memory) pair + jointly with a fastembed reranker (`[embedder] reranker` = a curated id; + local default ms-marco-tinybert-l-2-v2; "off" disables), drop below a 0.30 relevance floor, truncate to the cap. + Every knob was chosen by measurement: `jina-reranker-v1-tiny-en` + (default) beat the larger turbo model on both quality and speed in the + head-to-head benchmark, a pool of 6 matches pool-12 quality exactly at + half the latency, and summaries must stay FULL (snippet truncation + cratered recall@4 from 0.83 to 0.66, worse than FTS). With those + settings a warm rerank answers inside the 300ms hook budget on a real + brain (~265ms measured); slower machines degrade gracefully to + floored-FTS for that turn, or set `reranker = "off"`. Backing the + default path, the cosine floor: `broker.min_semantic_score` is + now ON by default (0.35) *and actually wired* (it previously defaulted + to 0.0 and was never populated from config in any production path). The + hook's daemon budget tightens 750ms → 300ms; a warm semantic answer + fits with ~70ms to spare, and misses fall back to floored FTS. Daemon + spawn hygiene for the lazy path: the entrypoint now binds the socket + BEFORE loading models (a redundant spawn exits in ms, not seconds), and + on Windows the hook clears HANDLE_FLAG_INHERIT on its std handles before + spawning so the long-lived daemon can never hold the harness's stdout + pipe open (previously the first prompt of a session could stall until + the host's hook timeout). New `kimetsu brain eval [--fixture ...]` + measures recall@2/4 + MRR across fts / semantic / semantic+rerank modes + against a committed fixture (`fixtures/eval-retrieval.json`), so ranking + changes are measurable: baseline shows semantic recall@4 0.90 / MRR 0.91 + vs FTS 0.72 / 0.81. `--rerankers ` benchmarks cross-encoders + head-to-head (quality + per-query latency) and `--pool` sweeps pool + sizes; non-curated models load as user-defined ONNX from any HuggingFace + repo via hf-hub. Benchmark results: jina-tiny recall@4 0.896 / MRR 0.938 + at ~44ms per query (pool 6) vs turbo 0.833 / 0.875 at ~137ms (pool 12); + ms-marco TinyBERT-L-2 is ~5× faster still (8.5ms) but its quality + (0.715) merely matches FTS. + * **Warm embedder daemon: semantic recall at hook time.** The + `UserPromptSubmit` context-hook can now match memories by *meaning*, not + just lexically. A single per-user daemon (`kimetsu brain embed-daemon`, + keyed by embedder model) loads the ONNX model once and serves full + embedding/ANN retrieval to the hook over a local socket / named pipe + (`interprocess`); the hook is a thin client with a ≤300ms budget and a + hard fall-back to floored-FTS, so the prompt is never blocked. `kimetsu + brain warm` (wired to each harness's startup hook) pre-warms it so a + running session never pays a cold model load. One model in RAM regardless + of how many projects/agents are active. Config: `[embedder] daemon` and + `warm_on_start` toggle it; `[embedder] model` (and `kimetsu brain model + set`) pick the model. `KIMETSU_EMBED_DAEMON=0` is a runtime kill switch. + Embeddings builds only; lean builds keep the floored-FTS hook. New + `kimetsu brain daemon status|stop` to inspect/control it. + * **Durable schema migrations.** brain.db now migrates forward + automatically on open via a versioned, forward-only runner (each + migration applied in one transaction). The DB is backed up to a + `brain.db.bak-*` sidecar before any version-advancing migration + (skipped for empty brains; the three newest backups are kept). + Read-only opens of an un-migrated brain degrade gracefully; an + event-upcast seam keeps old traces replayable. The project.toml + config version is decoupled from the DB schema version so the + schema can evolve without breaking existing projects. + * **Proof-of-value analytics.** New `kimetsu brain insights` command + and `kimetsu_brain_insights` MCP tool: retrieval hit-rate & + skip-rate, citation rate, proposal acceptance rate, usefulness + trend, harvest yield, corpus health, and token economy, computed + over a configurable recent-runs window. A new `context.served` + event records every retrieval (hit or miss); `context.injected` + now carries injected-token counts. + * **Semantic retrieval (usearch HNSW ANN).** On the embeddings build, an + approximate-nearest-neighbour index (usearch HNSW) finds memories whose + *meaning* matches the query even with no shared words: **O(log N) per + query**, so retrieval stays fast as the corpus grows. The index is + candidate generation only; final ranking is an exact cosine rerank over the + stored f32 vectors, so the index can be quantized (**f16 by default**, + `i8`/`f32` via `KIMETSU_ANN_QUANTIZATION`) for a large RAM saving with + negligible quality loss. Retrieval is sharpened with embedding-MMR + (collapses true paraphrase duplicates) and an absolute semantic-relevance + floor (genuinely off-topic queries return nothing). Capsule caps are + config-driven (default 8) and injected tokens drop while the relevant + capsule is preserved. The lean (FTS-only) build is unchanged. + * **Scales to ~1M memories.** A million-memory corpus runs on modest + hardware: **~1.8 s p99 semantic retrieval and ~3 GB RAM at 1M** (f16 + default; ~2.8 GB with `KIMETSU_ANN_QUANTIZATION=i8`). Both retrieval *and* + conflict-detection-on-write are O(log N) via the HNSW index, no + brute-force vector scan. Bulk ingest batches embedding; the index builds in + parallel across cores, maintains itself incrementally, persists a sidecar + so a restarted server loads instead of rebuilding, and Kimetsu Remote + pre-warms each repo's index on startup. + * **Proactive & cost-shrinking recall (the agent brain).** Before the + first implementation attempt, a tight retrieval surfaces a "Known + pitfalls" block (failure patterns / conventions), proactive, not + just post-failure. Tasks are classified (Debug / Feature / Refactor / + Docs / Investigation) to route recall by kind. A per-run recall + ledger deduplicates capsules across stages (rendered once, + back-referenced after), and the long tail is injected as one-line + headlines the agent expands on demand via a new `expand_capsule` + tool, so brain overhead shrinks in relative terms as tasks grow + (an adaptive sublinear, per-run-capped budget). + * **`kimetsu config edit` and `kimetsu run abort`** are now fully + implemented: `config edit` opens `$EDITOR` on project.toml and + re-validates on save; `run abort` cleanly finalizes a dangling run. + No stub subcommands ship. + * **`kimetsu doctor --selftest`** proves the brain pipeline works + end-to-end (ingest → retrieve → record) without needing a live + model or network. + * **Process & maintenance commands.** `kimetsu ps` / `stop` / + `restart` list and stop running MCP servers (the host respawns one + on the next tool call); `doctor` now flags a stale running MCP + server after an update. `kimetsu brain export` / `import` move + memories between brains as portable JSON; `kimetsu brain memory + edit` / `undo` fix a bad recording in place; `kimetsu runs prune` + and `kimetsu brain compact` (VACUUM, optional event-trim) keep the + install lean. + * **Kimetsu Remote (beta): the brain over HTTP MCP.** Under active testing; + the `kimetsu-remote` **server is a separate package** and is NOT installed by + `cargo install kimetsu-cli` / `npm i -g kimetsu-ai`: install it on the + server with `npm install -g kimetsu-remote` or `cargo install kimetsu-remote + --features embeddings` (or its standalone GitHub-Release archive). A new + standalone `kimetsu-remote` server hosts one brain per repository under a + data dir and exposes the memory/retrieval/curation tools over remote MCP + (`POST /mcp/{repo}`), so a team (or you across machines) can share one + brain with no local checkout. Bearer-token auth (global or per-repo); + repo-keyed (the client supplies the id, derivable from the git remote); + the agent-facing pure-DB tool subset only (workdir/host-local tools are + excluded). Each repo brain is standalone (user-brain merge off). Plain + HTTP: terminate TLS at a reverse proxy. `kimetsu-remote serve --addr + 0.0.0.0:8787 --data --token ` (build with `--features embeddings` + for semantic retrieval). Wire a host with `kimetsu plugin install + --remote [--repo ] [--token ]`: it + writes a `url`+`Authorization` MCP entry (no local hooks), deriving the repo + id from your git remote and referencing `${KIMETSU_REMOTE_TOKEN}` by default + so the secret isn't written to disk. The server ships as a separate package + (`npm i -g kimetsu-remote` / `cargo install kimetsu-remote --features + embeddings`) with its own standalone release archive. Hardening: per-token + rate limiting + (`--rate-limit ` → 429 when exceeded), a structured per-request log + + an unauthenticated `GET /metrics` (Prometheus text, aggregate counts by + outcome, no repo labels), and optional in-process HTTPS (build + `--features tls`, pass `--tls-cert`/`--tls-key`; rustls/ring, off by default + a reverse proxy is still the recommended terminator). Optional shared + **org brain** (`--org-brain `, outside `--data`): `global_user`-scoped + memories are stored there and merged into every repo's retrieval + (cross-project team memory), while `project`-scoped memories stay per-repo. + Off by default: each repo brain is standalone. Optional **server-side + ingest** (`--repos-file` + `--checkout-dir`): the operator pre-registers + repo-id → git URL, the server clones/refreshes a managed checkout, and + `kimetsu_brain_ingest_repo` indexes its files into the repo's brain so + `context` retrieval includes file capsules remotely (clients can't trigger + arbitrary clones; private repos use the server's own git auth). + * **AWS Bedrock provider.** The agent *and* the auto-harvester can run + on Anthropic models served through Amazon Bedrock (InvokeModel, + SigV4-signed from `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` + (+ optional `AWS_SESSION_TOKEN`) and `AWS_REGION`, no AWS SDK). Set + `[model] provider = "bedrock"` and/or `[learning.distiller]`; the two + are configured independently, so you can run the agent on Bedrock and + harvest on Bedrock or direct Claude/OpenAI. + * **Two more host integrations: Pi and OpenClaw.** `kimetsu plugin install + pi` wires a TypeScript extension (Pi has no MCP) plus a `kimetsu-brain` + skill; `kimetsu plugin install openclaw` registers the MCP server, a + hooks plugin, and a `kimetsu-context` skill. Both join Claude Code and + Codex across `plugin status`, `plugin uninstall`, and `setup`. + *Which* hosts you wire is a runtime choice you change anytime, no + reinstall. **Every official prebuilt + npm binary (lean and embeddings) + includes all four host integrations;** they're opt-in Cargo features only + for a minimal source build, added with `--features pi,openclaw`. Every + embedded hook degrades to a silent no-op if the `kimetsu` binary isn't on + PATH, so a host is never left broken. + * **Full plugin lifecycle.** `kimetsu plugin status` shows what's wired + where (host × scope: installed / partial / absent + which pieces); + `kimetsu plugin uninstall ` removes only the wiring (keeping the + binary + brain); `kimetsu setup` runs init + plugin install + a + selftest in one command. `kimetsu brain backup` writes a consistent + full-DB snapshot via the SQLite online-backup API. + * A 5-minute quickstart was added to the README. + +CHANGED + * **Lean `.kimetsu/`.** The `brain.db` events table is now the + durable log: memory writes no longer create per-write `runs//` + directories, so a brain-only `.kimetsu/` holds just `brain.db` + + `project.toml`. Transient proactive / chat / bench output moved to + `~/.kimetsu/cache/`. + * **Bidirectional config: every optional feature is turn-off-able.** + `[embedder] enabled`, `[broker] ambient`, `[kimetsu] use_user_brain` + (plus the existing `[learning] auto_harvest` / distiller and + `[shell] redact_secrets`) are honored at runtime with the precedence + env override > config > default. New `kimetsu config set` / `get` + read and flip them from the CLI. + * **Tiered, non-orphaning uninstall.** `kimetsu uninstall` now removes + the host plugin wiring (Claude Code & Codex hooks / MCP / skills / + agents, workspace + global) via a 3-tier prompt (binary only / + + plugins (default) / + brains (typed confirm)) so it no longer + leaves hosts pointing at a missing binary. A binary locked by a + running kimetsu process is handled (offer to stop it / deferred + delete) instead of a misleading "needs admin". + * **Install/upgrade hardening.** Golden tests lock the + non-destructive config-merge for Claude/Codex hooks, MCP config, + and CLAUDE.md (user content always preserved; re-installs are + byte-idempotent). Windows now runs the full test suite in PR CI. + * **Clippy is a hard CI gate** (`-D warnings`) on both the lean and + embeddings builds. + * **Retrieval ordering is fully deterministic:** a stable tiebreak + eliminates non-reproducible ranking across runs. + * **Terser `--help` menu + flavored `--version`.** Top-level commands + show short imperative labels (full detail stays in + `kimetsu --help`), and `kimetsu --version` reports the build + flavor (`1.0.0 (embeddings)` vs `(lean)`) so semantic-search + availability is obvious at a glance. + * **Run dirs self-prune.** New agent runs opportunistically GC run dirs + older than 30 days (keeping the newest 20; `KIMETSU_RUNS_GC=0` to + disable), only at run creation, never on the hot brain-open path. + * **One-command npm semantic build.** `kimetsu npm-flavor embeddings` + fetches the semantic build once and persists the choice (in + `/kimetsu/npm/flavor`), so npm users no longer keep + `KIMETSU_NPM_FLAVOR` exported across runs; `lean`/`status` round it out + (the env var stays a per-run override). + +FIXED + * **Lexical retrieval no longer injects off-topic memories that merely + share the project name.** A broad conceptual prompt ("tell me about + kimetsu, what's the idea of the repo") surfaced narrow debugging + war-stories whose only overlap with the query was the corpus-ubiquitous + token "kimetsu". Root cause: on the FTS-only `UserPromptSubmit` hook path + there was no relevance floor (the cosine-based `min_semantic_score` is + inert without an embedding), and `normalize_and_score` divides relevance + by the *per-kind* max, so the best memory of each kind became + `relevance = 1.0` no matter how weak the actual match, easily clearing + the `min_score` gate on freshness + confidence alone. New + `broker.min_lexical_coverage` floor (default 0.5): query tokens are + stripped of stopwords and IDF-weighted over the memory corpus (so the + project name, present in nearly every memory, contributes ~0; a word in + *no* memory also contributes 0 since it can't discriminate), and a memory + is dropped before scoring when the IDF-weighted share of the query it + covers is below the floor and it has no semantic support. Repo-file and + manifest capsules pass through untouched. Memories whose only match is the + project name are now reliably dropped; the brain stays silent rather than + injecting noise. (Keyword-overlap-but-off-topic hits that match a real, + non-ubiquitous word still need the semantic path; this is a lexical floor.) + * **`Stop` hook no longer trips "invalid stop hook JSON output".** + `kimetsu brain stop-hook` printed a bare-text banner on stdout, but + Claude Code validates a Stop hook's stdout as the advanced JSON + control object, so the banner was rejected. The hook now emits a + well-formed JSON object: informational banners via `systemMessage`, + and the end-of-session harvest cue via `decision: "block"` so the + cue text actually re-enters the model (plain stdout never reached it + in a Stop hook, so the cue was previously inert). The one-cue-per- + session guards keep blocking from looping. + * **MSRV portability.** A 1.87-only API that violated the declared + `rust-version = "1.85"` MSRV was replaced with the compatible + 1.85 equivalent. + * **GlobalUser memory writes work from any directory again:** a + regression where recording a global-user memory required a loadable + project is fixed. + * **`UserPromptSubmit` context-hook no longer risks the host's 30s + timeout.** The per-prompt hook runs in a throwaway process that + can't reuse the long-lived MCP server's warm model cache, so in the + embeddings build it was paying a cold fastembed/ONNX model load on + every prompt, fast on a warm OS file cache but able to exceed 30s + on a cold first prompt (worst under disk contention / AV scanning), + which fails the hook. The hook is now FTS-only (lexical retrieval, + no embedding model loaded); semantic ANN recall stays with the warm + MCP `kimetsu_brain_context` tool the agent calls. Steady-state hook + latency drops to ~300 ms regardless of build flavor. + +## v0.9.0: auto-harvested memories + SessionEnd distiller + +ADDED + * **Credentialed SessionEnd distiller (opt-in).** A second, deterministic + memory-harvest path alongside the v0.9.0 in-agent harvester. `kimetsu plugin + install claude-code` and `kimetsu plugin install codex` now run an + interactive wizard (on a TTY; skip with `--no-setup`, force with + `--setup-harvest`) that configures a cheap distiller + model: Anthropic (recommended `claude-haiku-4-5`), OpenAI (recommended + `gpt-5.4-mini`), or compatible endpoints via `ANTHROPIC_BASE_URL` / + `OPENAI_BASE_URL`. The key + base URL are written to a gitignored `.env`; + the selection lands in `[learning.distiller]` + in `project.toml`. A new `SessionEnd` hook for Claude Code runs + `kimetsu brain session-end-hook`; Codex uses its supported `Stop` hook with + `--distill-on-stop`. When enabled + credentialed, the distiller reads the + transcript with that model and records lessons through the confidence-gated + `propose_or_merge_memory`. When the distiller is enabled, the Stop hook's + end-of-session cue is suppressed (the distiller owns end-of-session; the + mid-session PostToolUse resolved-failure cue stays). `AnthropicProvider` + gained an optional base URL for the LiteLLM case, and the distiller gained + an OpenAI Responses API provider. With `--scope global` the + wizard configures the distiller once in `~/.kimetsu/` (config + `.env`); that + global distiller then runs in every project and records into the user brain + (`~/.kimetsu/brain.db`, available everywhere), with a per-project distiller + taking precedence when one is configured. + * **Auto-harvested memories (in-agent).** The hooks now drive memory + *generation*, not just retrieval. When a command that failed earlier in the + session succeeds (PostToolUse), or a non-trivial session ends with nothing + recorded (Stop), Kimetsu emits a `[kimetsu-harvest]` cue telling the agent to + dispatch a new background **`kimetsu-memory-harvester`** subagent (installed + at `.claude/agents/` for Claude Code and `.codex/agents/` for Codex, pinned + to a cheap model). The subagent distills 0-3 + generalizable lessons and records them through the confidence-gated + `kimetsu_brain_record` path: no separate API key or kimetsu-side model + credentials, billed in-agent at the cheap model's rate, non-blocking. Cues + are throttled (at most ~once per resolved failure / once per session) and can + be disabled with `[learning] auto_harvest = false` in `project.toml`. + +CHANGED + * **Cleaner help & tool menus.** Stripped internal version-history prefixes + (`v0.x:`, `MP-…:`) from `--help` text and the MCP tool/argument descriptions + so menus read as plain present-tense descriptions. (Internal code comments + are unchanged.) + +FIXED + * **Stop hook read the wrong field.** The Stop hook counted + `kimetsu_brain_record` calls from a non-existent inline `transcript` array; + Claude Code actually passes a `transcript_path` to a JSONL file. It now reads + the JSONL (with the inline array kept as a fallback), counts both the bare + and MCP-namespaced (`mcp__kimetsu__kimetsu_brain_record`) tool names, so the + "lessons recorded" banner and end-of-session cue actually fire. The JSONL is + now streamed line-by-line so a long session's multi-MB transcript never + lands in memory at once. + * **BOM-tolerant install.** `kimetsu plugin install` now strips a leading + UTF-8 BOM before parsing an existing `settings.json` / `hooks.json` / + `config.toml` / `.mcp.json`, so a config saved by a BOM-emitting editor + (e.g. older Windows Notepad) no longer fails with "expected value at line 1 + column 1". + * **Install polish.** The installer now **merges** Kimetsu's guidance into an + existing `CLAUDE.md` (workspace `.claude/CLAUDE.md` or the global + `~/.claude/CLAUDE.md`) inside ``/`` + markers, appending and upgrading in place, never overwriting the user's + content. `--force` no longer overwrites `CLAUDE.md` (the whole install is + idempotent and non-destructive; the flag is retained only for compatibility). + A `--scope global` on the workspace-only `kimetsu` target warns instead of + silently doing nothing; `--workspace` is canonicalized leniently so a global + install doesn't fail on a missing workspace path. + +## v0.8.4: non-destructive plugin install + global scope + +ADDED + * **Global plugin install.** `kimetsu plugin install --scope global` + installs the Kimetsu surface into the user's home for every session + (`~/.claude/` + `~/.claude.json` (`mcpServers`) for Claude Code, and + `~/.codex/` for Codex) instead of the workspace. `--scope` defaults to + `workspace` (the prior behavior). Also exposed as the `scope` argument on + the `kimetsu_plugin_install` MCP tool. + +FIXED + * **Hook install no longer clobbers existing hooks.** `kimetsu plugin install` + now *merges* its hooks into existing Claude `settings.json` / Codex + `hooks.json` instead of replacing them. Hooks you already have, even on the + same events Kimetsu uses (`UserPromptSubmit`, `PreToolUse`, …), are + preserved, with Kimetsu's group added alongside. Re-running install is + idempotent (no duplicate groups) and the MCP config + generated docs refresh + without requiring `--force`. + +## v0.8.3: npm distribution + +ADDED + * **npm distribution.** Kimetsu now publishes to npm: `npm install -g kimetsu-ai` + installs the prebuilt native binary for your platform, no Rust toolchain + required. Uses the esbuild/turbo model: per-platform packages + (`@kimetsu-ai/linux-x64`, `@kimetsu-ai/darwin-x64`, `@kimetsu-ai/darwin-arm64`, + `@kimetsu-ai/win32-x64`) selected via `optionalDependencies`, with a thin + `bin/cli.js` launcher that execs the matching binary. No postinstall, so it + works under `npm install --ignore-scripts`. The semantic build is fetched on + demand when `KIMETSU_NPM_FLAVOR=embeddings` is set.

Stale advice and silent passengers decay and get pruned. +- **Answers, not just injects.** `kimetsu ask` composes a grounded, cited + answer from memory using a local model: zero frontier tokens, works offline. + Lessons cited often enough graduate into runnable skills. +- **Pays for itself.** ~13x cheaper per solved task than a no-brain baseline on + a recorded Terminal-Bench slice, and the ROI ledger shows the savings on your + own work. +- **Stays yours.** The whole brain is one SQLite file per project.

Region resolution precedence (mirrors AWS SDK convention): +//! 1. `config.model.region` literal (project.toml) +//! 2. env-var named by `config.model.region_env` (default `AWS_REGION`) +//! 3. `AWS_DEFAULT_REGION` env-var +//! +//! `_key_override` is a NO-OP for Bedrock (the AWS credentials come from the +//! three dedicated env-vars, not a single "API key"). The parameter is kept +//! so `from_config_with_key` has the same signature shape as the other +//! providers. + +use std::path::Path; +use std::time::{Duration, SystemTime}; + +use aws_credential_types::Credentials; +use aws_sigv4::http_request::{SignableBody, SignableRequest, SigningSettings, sign}; +use aws_sigv4::sign::v4; +use kimetsu_core::KimetsuResult; +use kimetsu_core::config::ProjectConfig; +use kimetsu_core::env_file::resolve_env_value; +use kimetsu_core::secret::SecretString; +use reqwest::blocking::Client; + +use crate::anthropic::{anthropic_error_summary, build_anthropic_body, parse_anthropic_response}; +use crate::model::{ModelProvider, ModelRequest, ModelResponse}; + +const BEDROCK_ANTHROPIC_VERSION: &str = "bedrock-2023-05-31"; +const BEDROCK_SERVICE: &str = "bedrock"; + +#[derive(Debug, Clone)] +pub struct BedrockProvider { + client: Client, + access_key: SecretString, + secret_key: SecretString, + /// `None` when no session token was configured (long-term credentials). + session_token: Option, + region: String, + model_id: String, + // Stored for potential future use (e.g., override request defaults). + // Not read in the current `complete` implementation because the request + // carries its own max_output_tokens and temperature. + #[allow(dead_code)] + max_output_tokens: u32, + #[allow(dead_code)] + temperature: f32, + // Stored alongside the client for diagnostics / clone equality; the + // client already has the timeout baked in from construction. + #[allow(dead_code)] + timeout_secs: u64, +} + +impl BedrockProvider { + /// Construct from project config.

S5.1 + S5.2 + S5.3: `RetrievalBackend` trait — the seam between candidate +//! generation and the broker. +//! +//! # Boundary +//! +//! The trait covers **memory candidate generation** only: given a query and an +//! optional pre-computed query embedding, produce the raw `Candidate` pool that +//! the broker (scoring, floors, rerank, compression) then operates on. +//! +//! Repo-file and manifest candidates are NOT part of the backend — they are +//! project-local and always generated the same way regardless of which backend +//! is active. This keeps the blast radius small: the broker is entirely +//! backend-agnostic. +//! +//! # Flat backend +//! +//! [`FlatBackend`] is the default. It is a pure refactor-in-place: +//! it delegates to the existing `context::memory_candidates_flat` function, so the +//! FTS + usearch-ANN candidate path is UNCHANGED. +//! +//! # Graph-lite backend (S5.2) +//! +//! [`GraphLiteBackend`] is a SUPERSET of flat: it starts with the flat +//! candidate set and then expands 1–`MAX_HOPS` hops over the +//! `memory_edges` typed-edge projection table (created by the v3→v4 migration). +//! +//! The expansion uses a recursive CTE rooted on the flat hit set, bounded by +//! `MAX_HOPS` (default 2) and `MAX_FAN_OUT` (default 20 new ids per call). +//! Graph-reachable memories are marked with provenance `"graph"` in their +//! `ProvenanceRef.source` field so the broker can see they arrived via graph +//! traversal, though the broker's scoring treats them identically. +//! +//! Because graph-lite strictly adds candidates to the flat set, it cannot +//! reduce recall relative to flat — so enabling it can never make retrieval +//! worse, only broader. +//! +//! # PetgraphBackend (S5.3, `graph` feature, remote-only) +//! +//! [`PetgraphBackend`] is the Tier-2 full-graph backend. It is ONLY compiled +//! when the `graph` feature is active (enabled by `kimetsu-remote`; never in +//! the local lean/CLI builds). It loads the entire `memory_edges` table into an +//! in-memory `petgraph` directed graph at construction time, enabling real +//! graph algorithms: +//! +//! * **Candidate expansion**: like graph-lite but operates on the petgraph +//! in-memory graph — `BFS` up to `MAX_HOPS` without SQLite round-trips per +//! hop. The candidate set is a SUPERSET of flat (no recall loss). +//! * **Centrality** (`node_centrality`): degree centrality per node — identifies +//! the most-referenced memories (high in-degree = frequently consolidated into; +//! high out-degree = memory that was itself superseded many times). Exposed for +//! future remote endpoints (consolidation hints, importance ranking). +//! * **Shortest path** (`shortest_path`): BFS shortest path between two memory +//! ids — answers "why are these two memories connected?" for explainability +//! endpoints. +//! * **Community detection stub** (`community_hints`): returns the weakly +//! connected components as cluster ids — a lightweight proxy for community +//! detection. Full Louvain is deferred until the corpus justifies it. +//! +//! The graph is rebuilt from `memory_edges` at backend construction. Since +//! `memory_edges` is a rebuild-safe projection (rebuilt from the event log on +//! `rebuild_in_place`), re-constructing `PetgraphBackend` is always safe. +//! +//! ## v2.5 decision criterion (S5.4) +//! +//! The cross-backend benchmark (`BackendBenchResult`) documents the measured +//! numbers and the criterion for whether an embedded graph DB (Kùzu/Cozo) is +//! justified at v2.5.

The rule layer is fully deterministic and model-free: it parses inline +//! `[tags: ...]` markers (via [`crate::consolidate::parse_tags`]) plus a small +//! salient-term pass, indexes memories by entity, and links every pair that +//! shares at least one entity. The optional LLM enrichment layer (`--enrich`) +//! lives in the CLI, where the cheap-model provider is resolved. +//! +//! Edges are persisted as `memory.edge` events via +//! [`crate::projector::add_memory_edges`], so they are rebuild-safe. + +use std::collections::{BTreeMap, BTreeSet}; + +use kimetsu_core::KimetsuResult; +use rusqlite::Connection; + +use crate::consolidate::parse_tags; + +/// A proposed relation edge between two active memories. +#[derive(Debug, Clone, PartialEq, Eq, PartialOrd, Ord)] +pub struct EdgeProposal { + pub src_id: String, + pub dst_id: String, + pub edge_type: String, +} + +/// The rule-layer edge type. +pub const RELATES_TO: &str = "relates_to"; + +/// Default cap on how many edges any single memory may originate, to stop a +/// common entity (shared by many memories) from producing a quadratic hairball. +pub const DEFAULT_MAX_FAN_OUT: usize = 8; + +/// Minimum length for a salient bare keyword to count as an entity.
