From 890754589239393bedabba8d347959de9d1613c0 Mon Sep 17 00:00:00 2001 From: RodCor Date: Wed, 3 Jun 2026 12:05:27 -0300 Subject: [PATCH 001/136] feat: decouple project.toml config version from DB schema version Introduce KIMETSU_CONFIG_VERSION (the project.toml format version), separate from KIMETSU_SCHEMA_VERSION (the brain.db schema). The DB schema can now advance via migrations without forcing project.toml rewrites or breaking existing projects on open. Prep for the schema-migration runner.

Analytics now computes retrieval hit-rate, avg top score, and skip-rate over a time window (hook events have no run, so they're counted by timestamp). Removes the n/a-until-C7 placeholders.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add a derived vec0 index (memory_vec) reconciled on demand from memories, and union a KNN semantic-recall pass into memory_candidates on embeddings builds — finding memories whose meaning matches the query even when no words overlap (replacing the recency-bounded fallback). Rebuilds on embedder change; lean (FTS-only) retrieval is unchanged. Derived structure, not a numbered migration, so lean/embeddings DB schema stays identical. D1b: ensure_vec_index() creates memory_vec (vec0, TEXT PRIMARY KEY mapping via approach 1: vec0(memory_id TEXT PRIMARY KEY, embedding float[D])) plus memory_vec_meta tracking the active (model_id, dim). Drops and recreates on embedder change; incremental INSERT/DELETE reconciliation on each call. D1c: memory_ann_candidates() runs a KNN query (MATCH + ORDER BY distance + LIMIT 80) on the vec0 index, fetches full memory rows, builds Candidates via memory_row_to_candidate. memory_candidates() on embeddings builds now unions FTS + ANN candidates, deduping by memory_id (higher raw_relevance wins). D1d: four new tests — ANN semantic match FTS misses (oracle embedder), vec index rebuild on model-id change, dedup guarantee, lean-unchanged path with NoopEmbedder. 151/151 tests pass on embeddings build; all workspace tests green; lean build clean.

Render caps honor the configured budget/max_capsules instead of a hard-coded 12, and defaults drop now that selection is more precise. Lean (FTS-only) retrieval unchanged. Token economy proven lower for the same queries with the relevant capsule preserved.

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 (sqlite-vec ANN).** On the embeddings build, an + approximate-nearest-neighbour index (sqlite-vec, statically linked) + finds memories whose *meaning* matches the query even with no shared + words. 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. + * **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. + * A 5-minute quickstart was added to the README. + +CHANGED + * **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. + +FIXED + * **MSRV portability.** A 1.87-only API that violated the declared + `rust-version = "1.85"` MSRV was replaced with the compatible + 1.85 equivalent. ## v0.9.0 — auto-harvested memories + SessionEnd distiller diff --git a/Cargo.lock b/Cargo.lock index 9f79b64..5abae4e 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1483,7 +1483,7 @@ dependencies = [ [[package]] name = "kimetsu-agent" -version = "0.9.0" +version = "1.0.0" dependencies = [ "blake3", "kimetsu-brain", @@ -1499,7 +1499,7 @@ dependencies = [ [[package]] name = "kimetsu-brain" -version = "0.9.0" +version = "1.0.0" dependencies = [ "blake3", "fastembed", @@ -1517,7 +1517,7 @@ dependencies = [ [[package]] name = "kimetsu-chat" -version = "0.9.0" +version = "1.0.0" dependencies = [ "base64 0.22.1", "crossterm", @@ -1532,7 +1532,7 @@ dependencies = [ [[package]] name = "kimetsu-cli" -version = "0.9.0" +version = "1.0.0" dependencies = [ "clap", "kimetsu-agent", @@ -1548,7 +1548,7 @@ dependencies = [ [[package]] name = "kimetsu-core" -version = "0.9.0" +version = "1.0.0" dependencies = [ "serde", "serde_json", @@ -1559,7 +1559,7 @@ dependencies = [ [[package]] name = "kimetsu-e2e" -version = "0.9.0" +version = "1.0.0" dependencies = [ "kimetsu-agent", "kimetsu-brain", diff --git a/Cargo.toml b/Cargo.toml index b946410..04a524b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -14,7 +14,7 @@ resolver = "3" # everything below except the per-crate `description`, `keywords`, # and `categories` which live in each `[package]` block since # crates.io enforces them per crate. -version = "0.9.0" +version = "1.0.0" edition = "2024" # Rust ecosystem dual-license (matches tokio, serde, fastembed-rs, # etc.).

Detect the locking PIDs, schedule a poll-until-unlocked deferred delete/replace that completes once they exit, and replace the misleading `rerun elevated` message with the real fix (stop the running kimetsu processes).

Wired into both main-model selection and the auto-harvester distiller, so a user can run the agent on Bedrock and harvest on Bedrock or direct Claude/ OpenAI (the distiller is configured independently). Shared Anthropic wire code is factored to pub(crate) and reused; new [model]/[learning.distiller] region(_env) config fields default cleanly so existing project.toml loads unchanged.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `openclaw` as an install/status/uninstall target. OpenClaw supports MCP natively, so Kimetsu registers `kimetsu mcp serve` in ~/.openclaw/openclaw.json plus a hooks plugin (auto context/record, silent no-op if the binary is absent) and a kimetsu-context SKILL.md. Config is read as JSON5 and rewritten as JSON (comments are not preserved — surfaced in the install report).

charset=UTF-8 Content-Transfer-Encoding: 8bit Strips the Windows \?\ path prefix from displayed paths; silences internal tracing INFO on normal CLI runs; rewrites doctor's stale v0.4.6 MCP-check copy; stops `kimetsu init` from silently wiring Claude (init now creates the project only — host wiring is `plugin install`/`setup`); reframes init + plugin install with a friendly summary + next-step footer and plain-language scope/mode; and gives the auto-harvest wizard a concrete intro (what it does, that it costs API money + sends the transcript to your chosen provider + stores the key in a gitignored .env) with the risk note shown before the key.

The primary product is the `kimetsu` CLI binary from `crates/kimetsu-cli`, backed by reusable runtime crates: + +- `crates/kimetsu-core`: shared configuration, paths, IDs, event and secret helper types. +- `crates/kimetsu-brain`: local SQLite brain storage, migrations, memory ingestion, retrieval, embeddings support, redaction, analytics, and locking. +- `crates/kimetsu-agent`: provider-neutral agent loop, model clients, harness/tool runtime, pipeline, and benchmark support. +- `crates/kimetsu-chat`: terminal REPL, MCP server, bridge tooling, skills, commands, and UI. +- `crates/kimetsu-cli`: top-level CLI, plugin installers, hooks, brain admin commands, update/uninstall, doctor, and process helpers. +- `crates/kimetsu-e2e`: in-process test harness, not a production runtime surface. + +The real assets are local memories in `.kimetsu/brain.db` and `~/.kimetsu/brain.db`, host-agent configuration files written into project or user config directories, provider credentials read from environment/config, update/download integrity, and the user's local filesystem and shell. The repository deliberately offers a lean default build: embeddings, Pi, and OpenClaw integrations are opt-in features. Optional npm packages and GitHub release archives distribute prebuilt binaries. + +## Threat Model, Trust Boundaries, and Assumptions + +Kimetsu generally runs with the privileges of the local developer account. There is no multi-tenant server boundary in the default product. Most security impact therefore comes from local privilege misuse, malicious project content, malicious or compromised release/download inputs, secret leakage into memory or logs, and unsafe host-agent tool exposure. + +Main trust boundaries: + +- User/developer to Kimetsu CLI: command-line arguments, environment variables, current working directory, workspace paths, project config, and host-agent config paths are operator-controlled but can be influenced by malicious repositories. +- Host agent to MCP server: JSON-RPC/MCP requests may come from Claude Code, Codex, or other configured hosts. The host agent can pass task text, memory text, file paths, tool arguments, and bridge requests. +- Kimetsu to local filesystem: the CLI and brain create, migrate, back up, delete, and rewrite files in project `.kimetsu/`, user `.kimetsu/`, host config directories, cache directories, install locations, and update targets. +- Kimetsu to external model providers: provider clients send prompts/messages/tool outputs to Anthropic, OpenAI, or AWS Bedrock according to operator configuration. API keys and AWS credentials must not be logged or stored in memories. +- Kimetsu to release infrastructure: update and npm/prebuilt install flows trust GitHub release metadata, archives, package scripts/manifests, and platform selection logic. +- Kimetsu to SQLite: memory text, task text, repo file content, traces, embeddings, analytics, and migration metadata cross into durable local storage. +- Kimetsu to subprocesses: bridge, chat tool runtime, benchmarks, hooks, and update/uninstall flows may execute commands or discover binaries. Command construction and target validation matter because malicious workspace content can shape inputs. + +Attacker-controlled or partially attacker-controlled inputs include MCP request payloads, memory text, task prompts, repository files ingested into the brain, project config files, `.env` content, host hook input JSON, CLI path arguments, release metadata if the release channel is compromised, and local files in untrusted repositories.

It may contain hostile config, huge files, secrets, symlinks, paths, or prompts intended to manipulate agent memory. -- A malicious host agent or intentionally invoked tool may already be highly privileged, but Kimetsu should avoid adding silent command execution, unsafe deletion, secret persistence, or update compromise. -- SQLite database corruption, interrupted migrations, and concurrent Kimetsu invocations are realistic operational hazards. -- Network responses from model providers and GitHub should be treated as untrusted data until parsed and validated. - -## Attack Surface, Mitigations, and Attacker Stories - -Primary surfaces: - -- Brain storage and retrieval in `crates/kimetsu-brain`: schema migrations, backup retention, event log projection, FTS queries, embeddings, repo ingest, redaction, user brain/project brain selection, and lock management. -- MCP/bridge/chat in `crates/kimetsu-chat`: JSON-RPC parsing, MCP method dispatch, bridge requests to other hosts, terminal commands, tool calls, and context injection. -- Agent runtime in `crates/kimetsu-agent`: prompt construction, provider clients, subprocess/tool execution, benchmark harnesses, pipeline traces, and recall ledger. -- CLI/update/install in `crates/kimetsu-cli`: plugin install/uninstall/status, `brain` admin commands, `doctor`, `update`, `uninstall`, hook handlers, path discovery, and process helpers. -- Distribution tooling: `.github/workflows`, `npm/kimetsu`, `scripts/`, and `bench/` source where it affects release packaging, credentials, or benchmark execution. - -Existing mitigations and controls visible in repository context: - -- Lean default feature sets in `Cargo.toml` keep embedding/ONNX-heavy dependencies out of normal builds unless explicitly enabled. -- `reqwest` is configured with `default-features = false` and `rustls-tls`, avoiding system OpenSSL coupling. -- `rusqlite` uses bundled SQLite, reducing platform variance. -- Brain migrations are documented as forward-only with online backups and transactional version bumps. -- The product uses local SQLite rather than an external vector DB or cloud telemetry. -- Secret redaction exists in `crates/kimetsu-brain/src/redact.rs`, and there is a shared secret helper in `crates/kimetsu-core/src/secret.rs`. -- Update/uninstall documentation says discovered binaries are limited to verified install locations rather than whole-disk scans. - -Realistic attacker stories: - -- A malicious repository causes Kimetsu to ingest secrets, huge files, or adversarial memory content, leading to secret persistence, excessive CPU/disk use, or prompt manipulation in later agent runs. -- A malformed MCP request or bridge payload triggers unintended file writes, command execution, or excessive memory allocation in chat/bridge/MCP handling. -- A compromised or spoofed update path delivers a binary archive that is not pinned or verified strongly enough before replacing an installed executable. -- A malicious project config or path argument tricks plugin install/uninstall/update code into modifying files outside intended host config or install directories. -- A provider credential leaks through logs, traces, memory records, panic output, or doctor/debug reports. -- Concurrent invocations corrupt the brain or race through migration/update/delete operations if locks and atomic writes are incomplete. - -Out-of-scope or lower-likelihood stories: - -- Cross-tenant data exposure is generally out of scope for local single-user execution unless Kimetsu is embedded into a shared service. -- Remote network exploitation of a public server is not the primary model because the product is a CLI/MCP sidecar, not a hosted web service. -- SQL injection becomes high impact only where untrusted input is interpolated into SQL syntax. Parameterized rusqlite statements reduce this class when used consistently. - -## Severity Calibration (Critical, High, Medium, Low) - -Critical: - -- Silent arbitrary command execution or arbitrary file deletion/write reachable from an untrusted MCP payload, hook input, project config, or malicious repository without an explicit user action. -- Self-update accepting an attacker-controlled binary without sufficient release/source validation, then replacing the running or installed `kimetsu` binary. -- Secret exfiltration from provider credentials or stored brain content to an attacker-controlled network endpoint without explicit operator configuration. - -High: - -- Path traversal or symlink-following in plugin install, update, uninstall, or brain migration that overwrites host config, shell startup files, or executables outside the intended targets. -- Ingest or memory-record flows that reliably persist high-value secrets despite the intended redaction layer. -- MCP/bridge methods that permit filesystem or process actions with insufficient path/command validation when reachable from a host agent in an untrusted project. -- Data-loss bugs in migrations, backup pruning, update replacement, or uninstall that can destroy the brain or unrelated user files. - -Medium: - -- Denial of service from unbounded file ingestion, adversarially large MCP payloads, expensive regexes, runaway embedding calls, or unbounded prompt/context construction. -- Race conditions that can corrupt local brain state or leave partial updates under normal concurrent use. -- Logging or doctor output that exposes sensitive paths, model names, or partial secrets but not full credentials. -- Supply-chain hardening gaps in release workflow permissions, npm package metadata, or archive selection where exploitation requires compromise of release infrastructure. - -Low: - -- Documentation or configuration drift that causes users to install a heavier feature set than intended, or misunderstand lean versus embeddings builds. -- Inefficient cloning, avoidable allocation, repeated SQL prepare/parse work, or non-streaming file reads that degrade local performance without changing security posture. -- Minor Rust style issues, needless dependencies, or test-only code risks that are not reachable in production builds. - diff --git a/.gitignore b/.gitignore index 099383e..b357343 100644 --- a/.gitignore +++ b/.gitignore @@ -44,3 +44,6 @@ .claude/ .codex/ .mcp.json + +# Local Codex security-scan artifacts (not part of the project) +.codex-security-scans/ From c75ba914ffb76786d75cd1a01311b7517e7f7c4c Mon Sep 17 00:00:00 2001 From: RodCor Date: Thu, 4 Jun 2026 22:42:56 -0300 Subject: [PATCH 066/136] build: bundle Pi + OpenClaw into all prebuilt + npm binaries MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Host integrations are about runtime flexibility, so coupling them to a heavy compile flavor was backwards.

Reuses the existing transport-agnostic dispatch (filtered to the pure-DB, agent-facing tool subset), keyed by a sanitized repo id in the URL path, behind bearer-token auth (global or per-repo, constant-time compared). Blocking brain calls run on a bounded spawn_blocking pool; per-repo file lock serializes writes (WAL gives concurrent reads); the user-brain merge is off so each repo brain is standalone. axum/tokio live only in this crate — verified out of kimetsu-cli. Lean by default; `--features embeddings` for semantic retrieval. Plain HTTP (terminate TLS at a proxy). Client wiring + release packaging are the next phase.

Optional in-process HTTPS lands behind a `tls` Cargo feature (rustls + ring to avoid the aws-lc-rs/NASM build on Windows): build `--features tls` and pass `--tls-cert`/`--tls-key`; off by default, a reverse proxy stays the recommended terminator. The embeddings release archives now build the server with `embeddings,tls`. The request handler is split into a metrics/logging wrapper over the auth→rate-limit→dispatch path.

Off by default (standalone repos). The dir is validated to live outside --data (repo-id collision guard), pre-initialized at startup, and a warning logs that global_user memories are now shared server-wide. Reuses the existing user-brain plumbing (KIMETSU_USER_BRAIN_DIR + enable); the read-only retrieval path already merges it. Integration test proves cross-repo sharing of global_user memories and per-repo isolation of project-scoped ones.

Instead `kimetsu-remote` ships as its own npm package (`npm install -g kimetsu-remote`, backed by @kimetsu-ai/remote- per-platform packages built with embeddings,tls) and its own standalone `kimetsu-remote--` GitHub-Release archive. There's no pip-style `kimetsu-ai[remote]` extras syntax in npm/cargo — a separate package is the idiom (cargo already has it: `cargo install kimetsu-remote`). Docs updated.

Called from both initialize() (RW path) and validate() (RO path). Covering index idx_memories_scope_model_active added in migrate_v1_to_v2 to speed the per-add conflict scan pool query. Fix 2 — conflict-detection off-switch (config.rs + conflict.rs) IngestionSection.detect_conflicts: bool (default true, serde). conflict_detection_enabled(config_value) reads KIMETSU_DETECT_CONFLICTS env with 0/false/off/no → disable; env overrides config. add_memory and propose_or_merge_memory honour the gate. Fix 3 — vec0 BLOB encoding (context.rs + embeddings.rs) All memory_vec insertions and MATCH queries now use raw f32 little- endian BLOB instead of JSON text (4× smaller, zero serialisation cost). vec_to_json removed. ensure_vec_table (DDL-only, no backfill) split from ensure_vec_index (full backfill for upgraded brains). upsert_vec_row does O(1) INSERT OR REPLACE called from embed_and_persist so memory_vec stays synchronised at add-time without any backfill scan. Fix 4 — ANN conflict detection + precomputed-vec reuse (conflict.rs) embed_and_persist now returns Option> so the caller can pass the computed vector directly into detect_and_record_with_vec, cutting embedding cost per add from 2× to 1×. find_potential_conflicts_with_vec queries vec0 ANN for a pool of max(top_k*8, 64) candidates then exact- scores only that pool, reducing the worst-case conflict scan from O(N) to O(pool_size). Falls back to SQL full-scan when vec0 is unavailable or the ANN pool is empty.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Replace the brute-force `sqlite-vec` (`vec0`) exact KNN with a `usearch` HNSW index so context retrieval AND conflict-detection-on-write become ~O(log N), unblocking the 1M-memory goal. + +**Architecture:** A new feature-gated module `crates/kimetsu-brain/src/ann.rs` wraps `usearch::Index`. The index is a derived, rebuildable cache: SQLite `memories.embedding` BLOBs stay the source of truth; a sidecar file `brain.usearch` (next to `brain.db`) plus a `.json` manifest persist the graph. The index is keyed by the brain's `rowid` (u64) and holds active rows only (`remove` on invalidate). A process-global registry caches one index per on-disk brain; in-memory test DBs rebuild transiently per query. Both call sites (retrieval, conflict) keep their existing exact cosine rerank — usearch only does candidate generation. + +**Tech Stack:** Rust (edition 2024), `usearch` crate (native HNSW, optional under the `embeddings` feature), `rusqlite` (bundled SQLite, WAL), existing `embeddings::{encode_embedding, decode_embedding, cosine_similarity}`. + +**Reference spec:** `docs/superpowers/specs/2026-06-06-tier3-hnsw-usearch-design.md` + +**Standing rules:** branch `release/v1.0.0`; push each phase as its own commit; NO PR, NO tag.

After all combos finish the orchestrator reads the JSON files, sorts by MRR, and writes bench/results/summary.md. Per-combo worker: loads embedder + reranker (measuring Windows WorkingSet RSS via K32GetProcessMemoryInfo), seeds a hermetic temp brain with KIMETSU_BRAIN_EMBEDDER set to the combo embedder so stored vectors match query vectors, then runs all 45 dataset cases with min_score=0.0/min_lexical_coverage=0.0 for unfiltered recall. Cargo.toml: adds Win32_System_ProcessStatus + Win32_System_Threading to windows-sys features for K32GetProcessMemoryInfo / GetCurrentProcess.

The config default becomes -1.0 = AUTO, resolved per session embedder: 0.35 for bge-family, disabled for others (jina-v2's own precision already keeps noise at ~1.2 capsules). Explicit non-negative config values are respected as-is. Re-run confirms jina-v2 remote recovers to MRR 0.903 / recall@4 0.966.

Code audit (no criticals): rerank_capsules now fails open on a score-count mismatch from a custom reranker instead of silently dropping the unscored tail; the remote bench wraps its spawned server in a kill-on-drop guard so error paths can't orphan a live server holding the port and temp dir.
