root	8fc6238dea	catalogd: Step 7 — daily retention sweep binary ... Per docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md §5 Step 7: "Subjects whose retention.general_pii_until < now AND status != erased get marked for review (don't auto-delete; legal needs to approve)." Per shared::types::BiometricConsent doc-comment (BIPA requirement on biometric data, max 3 years from last interaction): "Implementation MUST enforce daily expiration sweep against this field." Therefore the sweep checks BOTH retention clocks. Reports overdue subjects to data/_catalog/subjects/_retention_sweep_<YYYY-MM-DD>.jsonl. Idempotent: subjects already in {Erased, RetentionExpired} are skipped so daily runs do not append duplicate rows. Does NOT mutate subject manifests. Legal/operator owns the action (extend, flip status, schedule erasure). CLI: retention_sweep # dry-run (default), stderr only retention_sweep --apply # also write JSONL report retention_sweep --as-of <RFC3339> # alternate clock for forecast/test retention_sweep --storage-root <dir> # default ./data Tests: 8 unit tests on is_overdue covering all 5 SubjectStatus values, both clocks, BIPA-only path, and idempotency on already-flagged subjects. Live verification (100 subjects in ./data/_catalog/subjects): - now (2026-05-03): 0 overdue (correct — 4-year retention) - --as-of 2031-06-01: 100 overdue, 394 days past, jsonl report shape verified with biometric fields correctly omitted via serde skip_serializing_if when subject has no biometric clock.

root	2a4b316a15	subjects: 2nd scrum fix wave (token min, chain_tip, tampering, rebuild collision warn) ... Second cross-lineage scrum on Steps 5+6 returned 13 distinct findings, 0 convergent. Three BLOCK-class claims verified as false positives (cache IS written, per-subject Mutex IS in place, spawn IS safe under writer's lock). Five real fixes shipped: 1. audit_endpoint: legal token min length 16->32 (HMAC-SHA256 best practice, kimi) 2. subject_audit: new chain_tip() returns last hash from full log; audit_endpoint now reports chain_root from full chain instead of windowed slice (opus) 3. registry: rebuild loader now warns on sanitize collision (symmetric with put_subject's collision guard - opus) 4. audit_endpoint: tampering detection - if manifest expects non-empty chain_root but log returns 0 rows, flag chain_verified=false with explicit message (opus) 5. execution_loop::audit_result_state: tightened heuristic - error/denied/not_found only classify when no rows/data/results sibling (opus INFO) Tests: 17 catalogd subject + 6 gateway audit_result_state, all green. New: audit_result_state_does_not_classify_error_when_data_sibling_present, audit_result_state_status_is_authoritative_even_with_data.

root	15cfd76c04	catalogd + gateway: Step 6 — /audit/subject/{id} legal-tier HTTP endpoint ... Implementation of docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md §5 Step 6 + §4 (response shape) + §6 (auth model). The defense-against-EEOC- discovery surface is live: legal counsel hits one URL with one token, gets back a signed-by-HMAC-chain audit response naming every PII access for a subject in a time window. New module: crates/catalogd/src/audit_endpoint.rs (~340 LOC) - AuditEndpointState { registry, writer, legal_token } - router() exposes: GET /subject/{candidate_id}?from=ISO&to=ISO (full audit response) GET /health (liveness + token check) - require_legal_auth() — constant-time-eq compare against the X-Lakehouse-Legal-Token header. Avoids timing leaks on the token check without pulling in `subtle` for one comparison. - Token loaded from /etc/lakehouse/legal_audit.token (env-overridable via LH_LEGAL_AUDIT_TOKEN_FILE). Empty file or <16 chars = endpoint serves 503 with a clear reason. Token value NEVER logged. - Response schema: subject_audit_response.v1 with manifest + audit_log (rows + chain verification) + datasets_referenced + safe_views_available + completeness_attestation. New helper on SubjectAuditWriter: - read_rows_in_range(candidate_id, from, to) — returns rows in window, used by the endpoint to assemble the response without re-reading the entire chain. - verify_chain() now returns Ok(0) when the audit log file doesn't exist (empty = trivially valid). Prevents legitimate "no PII access yet for this subject" from showing as integrity=BROKEN in the audit response. Caller can detect "log was deleted" via comparison to SubjectManifest.audit_log_chain_root (when that mirror lands). main.rs: - Audit endpoint mounted at /audit ONLY when both subject_audit writer AND legal token are present. Disabled-by-default keeps the surface from accidentally serving in dev/bring-up environments without proper credentials. Tests (9/9 passing): - constant_time_eq (correctness on equal/diff/empty/length-mismatch) - missing_legal_token_returns_503 - missing_header_returns_401 - wrong_token_returns_401 - correct_token_passes_auth - audit_response_assembly_full_path (manifest + 3 rows + chain verify) - audit_response_window_filters_rows (time-bounded window) - empty_token_file_results_in_disabled_endpoint - short_token_file_rejected_at_load (<16 char min) LIVE end-to-end verification: 1. Plant signing key + legal token in /tmp/lakehouse_audit/ 2. Restart gateway with LH_SUBJECT_AUDIT_KEY + LH_LEGAL_AUDIT_TOKEN_FILE pointing at the test files 3. /audit/health → 200 "audit endpoint ready" 4. /audit/subject/WORKER-1 (no token) → 401 "missing X-Lakehouse-Legal-Token" 5. /audit/subject/WORKER-1 (wrong token) → 401 "X-Lakehouse-Legal-Token mismatch" 6. /audit/subject/WORKER-1 (correct token) → 200 + full manifest + 0 rows + chain_verified=true (empty log path) 7. POST /v1/validate with candidate_id=WORKER-1 → triggers WorkerLookup.find() via the AuditingWorkerLookup wrapper from Step 5 8. data/_catalog/subjects/WORKER-1.audit.jsonl now exists with 1 row (accessor.purpose=validator_worker_lookup, result=not_found, prev_chain_hash=GENESIS, valid HMAC) 9. /audit/subject/WORKER-1 (correct token) → 200 + manifest + 1 row + chain_verified=true + chain_rows_total=1 + completeness attestation The full audit-trail loop (PII access → audit row → chain → audit response) works end-to-end on the live gateway. NOT in this commit (future steps): - Step 7: Daily retention sweep - Step 8: Cross-runtime parity (Go side reads the same shapes) - Mirror chain root to SubjectManifest.audit_log_chain_root after each append (so tampering detection can use the manifest's cached root as ground truth) - Live row projection from datasets (currently caller follows up via /query/sql against the safe_views named in the response) - Ed25519 signature on the response (chain verification IS the v1 attestation; signing is future hardening per spec §10) cargo build --release clean. cargo test -p catalogd audit_endpoint 9/9 PASS. Live verification successful. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-03 03:52:04 -05:00
root	cd8c59a53d	gateway: Step 5 — wire SubjectAuditWriter into validator WorkerLookup ... Implementation of docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md §5 Step 5. Every WorkerLookup.find() call from the validator path now produces one audit row in the per-subject HMAC-chained JSONL. Failures are non-blocking — validator continues whether audit succeeds or fails. Approach: decorator pattern. WorkerLookup is a sync trait by design (validator's contract is "in-memory snapshot, no per-call I/O") and audit writes are async, so we can't expand the trait. Instead, a new AuditingWorkerLookup wraps the inner lookup, captures a tokio::runtime::Handle at construction, and spawns audit writes from sync find() onto that handle. The chain stays intact under spawn fan- out because the writer's per-subject Mutex (shipped in the previous scrum-fix commit) serializes same-subject appends regardless of how the spawn calls arrive. Files changed: crates/gateway/src/v1/auditing_worker_lookup.rs (NEW, 175 LOC): - AuditingWorkerLookup<inner: dyn WorkerLookup, audit: Option<Arc<Writer>>> - new() captures Tokio Handle if audit is Some - find() runs inner lookup, then spawns audit append with: accessor.kind = "validator_lookup" accessor.purpose = "validator_worker_lookup" fields_accessed = ["exists"] (validator only proves existence of a subject; downstream code reads policy fields separately and would have its own audit if those become PII) result = "success" if found, "not_found" otherwise - Audit-disabled path (audit: None) is a transparent passthrough — zero overhead, no panic, no runtime requirement. crates/gateway/src/v1/mod.rs: + pub mod auditing_worker_lookup; crates/gateway/src/main.rs: - Hoisted subject_audit_writer construction OUT of the V1State literal (declaration-order constraint: validate_workers needs access to the writer). The hoisted Arc is then reused for the V1State.subject_audit field. - validate_workers now wraps the raw lookup with AuditingWorkerLookup::new(raw, subject_audit_writer.clone()) Tests (4/4 passing): - find_existing_subject_writes_success_audit_row - find_missing_subject_writes_not_found_audit_row (phantom-id case) - audit_disabled_means_no_writes_no_overhead (None pathway) - many_finds_to_same_subject_produce_intact_chain (30 sequential spawns on the same subject — chain verifies all 30, regression against the race we fixed in catalogd subject_audit) Also catches the iterate.rs:324 phantom-ID check transparently — that codepath calls state.validate_workers.find(...) which now goes through the wrapper, so every phantom-id rejection logs an audit row for free. NOT in this commit (future steps): - Step 6: /audit/subject/{id} HTTP endpoint - Step 7: Daily retention sweep - Threading X-Lakehouse-Trace-Id from request through to audit row (currently audit row's accessor.trace_id is empty) cargo build --release clean. cargo test -p gateway auditing_worker_lookup 4/4 PASS.

root	e38f3573ff	subject manifests Steps 1-4 — fix scrum-flagged BLOCKs and WARNs ... 2026-05-03 cross-lineage scrum on the subjects_steps_1_to_4 wave returned 14 distinct findings, 0 convergent. opus verdict was HOLD with 3 BLOCKs around the audit-chain integrity. All real. Fixed: ────────────────────────────────────────────────────────────────── BLOCK 1 — opus subject_audit.rs:172 + execution_loop.rs:391 Concurrency race: append_line is read-modify-write; the gateway hook used tokio::spawn fan-out → two concurrent appends to the same subject both read the same prev_hash, both compute their HMAC from the same prev, second write silently overwrites first → row lost AND chain broken. Fix: - SubjectAuditWriter gains per-subject Mutex map. append() acquires the subject's lock for the duration of the read-modify-write. Different subjects still parallelize. - Gateway hook switches from tokio::spawn to inline await. Per-row cost is ~1ms (one object_store put); inline is correct AND cheap. - New regression test: 50 concurrent appends to the same subject, asserts all 50 land with intact chain. BLOCK 2 — opus subject_audit.rs:108 Non-deterministic canonicalization: serde_json serializes struct fields in declaration order. Schema evolution (adding/reordering fields) silently changes the bytes verify_chain hashes → chain breaks even when nothing was actually tampered with. Fix: - New canonical_json() free fn — recursive value rewrite to sort object keys alphabetically (BTreeMap projection), arrays preserve order, scalars pass through. Stable across struct evolution. - Both append() and verify_chain() now compute HMAC over canonical bytes, not declaration-order bytes. - New regression tests: alphabetical-key + array-order-preserved. WARN — opus execution_loop:401 Audit row's `result` was hardcoded to "success" for every Ok(result) including payloads like {"error":"not found"}. Misleads compliance. Fix: - New audit_result_state() free fn that inspects the payload top-level for error/denied/not_found/status signals (per spec §3.2 enum). Defaults to "success" only when no error signal. - 4 new tests covering each enum case + falsy-signals defense. WARN — opus registry.rs:735 Storage-key collision: sanitize_view_name(id) is the disk key, but the in-memory HashMap was keyed by raw candidate_id. Two distinct ids that sanitize to the same key (e.g. "CAND/1" and "CAND_1") would collide on disk while appearing distinct in memory; second put silently overwrites first; rebuild loads only one. Fix: - put_subject() / get_subject() / delete_subject() / rebuild() all key the in-memory HashMap by sanitize_view_name(id), matching the storage key shape. - Collision guard: put_subject() refuses (with clear error) when the sanitized key matches an EXISTING subject with a DIFFERENT raw candidate_id. - New regression test: put("CAND/1") then put("CAND_1") errors + first subject survives. WARN — opus backfill_subjects.rs:189 trim_start_matches strips REPEATED prefixes; the spec wanted one-shot semantics. Edge case unlikely in practice but real. Fix: - Switched to strip_prefix(&prefix).unwrap_or(&cid). One-shot. INFO — opus subject_audit.rs:131 Per-byte format!("{:02x}", b) allocates each iteration. Hot path on every append. Fix: - Replaced with const HEX lookup table + push() into preallocated String. Same output bytes, no per-byte allocation. ────────────────────────────────────────────────────────────────── Test summary post-fix: catalogd subject_audit: 11/11 PASS (added 4 new — concurrency race regression, parallel-different-subjects, canonical-key sort, canonical-array order) catalogd registry subject: 6/6 PASS (added 1 new — collision guard) gateway execution_loop subject: 10/10 PASS (added 4 new — audit_result_state enum coverage) All 27 subject-related tests green. cargo build --release clean. The convergent-zero scrum result was misleading on its face — opus caught real BLOCKs that kimi/qwen missed. Per feedback_cross_lineage_review.md: opus is the load-bearing reviewer; single-opus BLOCKs warrant manual verification, which here confirmed all three were correct.

root	fef1efd2ac	gateway: Step 4 — wire SubjectAuditWriter into tool dispatch ... Implementation of docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md §5 Step 4. Every tool result that returns rows referencing a subject now produces audit rows in the per-subject HMAC-chained JSONL. Failures non-blocking. Changes: v1/mod.rs: + V1State.subject_audit: Option<Arc<SubjectAuditWriter>> (None when key file missing — audit becomes a no-op with warning, PII paths still serve) main.rs: + Construct SubjectAuditWriter at startup from LH_SUBJECT_AUDIT_KEY env or /etc/lakehouse/subject_audit.key. Missing/short key = log warning + leave None (gateway boots, audit disabled). Same store as the rest of catalogd. execution_loop/mod.rs: + audit_subject_hits_in() — called after every successful tool dispatch. Walks the result JSON, finds candidate_id / worker_id fields, fires one SubjectAuditRow per (subject, fields) pair. Tokio::spawn so audit latency never adds to tool path. + collect_subject_hits() — free fn, recursive JSON walker. Handles: "candidate_id":"X" → audit candidate_id="X" "worker_id":42 → audit candidate_id="WORKER-42" (matches backfill convention) "worker_id":"42" → audit candidate_id="WORKER-42" (string form) Other fields in the same object become fields_accessed (so audit row records "this access surfaced name + phone for candidate X"). Ignores objects without id fields. Skips empty id strings. Recurses through nested objects + arrays. Tests (6/6 passing — gateway::collect_subject_hits_*): - finds_candidate_id_strings (basic case + fields_accessed extraction) - prefixes_worker_id_int (int → WORKER-N) - handles_worker_id_string (string → WORKER-N) - recurses_through_nested_objects (joins / mixed payloads) - ignores_objects_without_id_fields (no false positives) - skips_empty_id_strings (defensive) Per spec §3.2: failures are logged, never propagated. Better to leak an audit row than block a tool response. Operators monitor warning volume to detect audit-write regressions. NOT in this commit (future steps): - Step 5: Wire validator WorkerLookup similarly (each candidate_id resolved by FillValidator gets an audit row) - Step 6: /audit/subject/{id} HTTP endpoint - Step 7: Daily retention sweep - Mirror chain root to SubjectManifest.audit_log_chain_root after each append (currently the chain is verifiable via verify_chain() even without the manifest mirror; the mirror is an optimization) - Thread X-Lakehouse-Trace-Id from request through to audit row cargo build --release clean. cargo test -p gateway collect_subject_hits 6/6 PASS.

root	bce6dfd1ee	catalogd: Step 3 — backfill_subjects binary (BIPA-defensible defaults) ... Implementation of docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md §5 Step 3. Reads a parquet source, creates one SubjectManifest per row with the spec-defined safe defaults, persists via Registry::put_subject(). Defaults baked in (per spec §2 + §5 Step 5): - vertical = unknown (HIPAA fail-closed) - consent.general_pii = pending_backfill_review (NOT inferred_existing — BIPA defense) - consent.biometric = never_collected (no biometric data backfilled) - retention.general_pii_until = now + 4 years - retention.policy = "4_year_default" Conservative ergonomics: - --limit 1000 by default. --all to do the full source. - --dry-run for parse + count + sample without writes. - --concurrency 32 (bounded via tokio::sync::Semaphore). - Idempotent: skips subjects that already exist in catalog. - Progress reports every ~5% (or 5K rows, whichever smaller).

To extend to candidates table, re-run with --dataset candidates --key-column candidate_id (no prefix since candidate_id is already the canonical token there).

root	d16131bcab	catalogd: Step 2 — SubjectAuditWriter with HMAC chain ... Implementation of docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md Step 2. Per-subject append-only audit JSONL with HMAC-SHA256 chain. Local-first — no Vault, no external anchor (those are v2 if SOC2 Type II becomes contract-required; v1 deliberately stays small). shared/types.rs additions: - AuditAccessor — kind, daemon, purpose, trace_id - SubjectAuditRow — schema/ts/candidate_id/accessor/fields_accessed/ result/prev_chain_hash/row_hmac crates/catalogd/src/subject_audit.rs (NEW): - SubjectAuditWriter — holds signing key + per-subject latest-hash cache - from_key_file() — loads key from sealed file, requires ≥32 bytes - with_inline_key() — for tests + bring-up - append() — computes HMAC chain link, persists JSONL row, returns new chain root (caller mirrors to SubjectManifest.audit_log_chain_root) - verify_chain() — full re-verification of a subject's audit log, catches both prev_hash drift AND row-level HMAC tampering - scan_latest_hash() — cold-start path, finds prev_hash from JSONL tail - append_line() — read-modify-write pattern (object stores have no native append; same shape as the rest of catalogd's persistence) Crypto: HMAC-SHA256 via the standard `hmac` crate (added to workspace + catalogd deps; not implementing crypto by hand). Output is lowercase hex matching the rest of the codebase's SHA-256 conventions. Security choices: - NO Debug impl on SubjectAuditWriter — auto-deriving Debug would risk leaking the signing key into log lines. Tests work around this by matching on Result instead of using .unwrap_err(). - Key min length 32 bytes (HMAC-SHA256 block size guidance). - Failures are NOT swallowed — Result returned, caller decides whether to log + continue (per spec §3.2 the gateway tool registry SHOULD log + continue rather than block reads). Tests (7/7 passing): - first_append_uses_genesis_prev_hash - chain_links_each_append (3-row chain verifies) - separate_subjects_have_independent_chains (per-subject isolation) - tamper_detected_on_verify (mutation in middle of chain breaks verify) - cold_writer_picks_up_existing_chain (process restart preserves chain) - empty_candidate_id_rejected - key_too_short_rejected_via_file NOT in this commit (future steps): - Step 3: Backfill ETL from workers_500k.parquet (next per J) - Step 4: Wire gateway tool registry to call append() on every candidate_id returned by search_candidates / get_candidate - Step 5: Wire validator WorkerLookup similarly - Step 6: /audit/subject/{id} HTTP endpoint - Step 7: Daily retention sweep - Mirroring chain root to SubjectManifest.audit_log_chain_root (separate concern; do at the call site) cargo check --workspace clean. cargo test -p catalogd subject_audit 7/7 PASS.

root	bb5a3b3f5e	execution_loop: align overseer log/KB strings with reverted local route ... Yesterday's revert (d054c0b) changed the API CALL from cloud to local but missed the LogEntry + KB row that record what model fired. Result: honest API call to qwen3.5:latest, dishonest log/KB rows saying "claude-opus-4-7". That's a real audit-trail integrity issue — the record didn't match reality. Fixed: - LogEntry "system" role label (line 663) - KB row's "model" field (line 685) Both now correctly show "qwen3.5:latest". Build + restart + smoke 10/10 green. Gateway healthy. Side note: the only remaining "claude-opus-4-7" mentions in this file are now in COMMENTS describing the v1 cloud route + the revert rationale — those are documentation, not log fields. Safe to keep.

root	d054c0b8b1	REVERT cloud routing on hot path — back to local Ollama per PRD line 70 ... PRD line 70: "Everything runs locally — no cloud APIs, total data privacy." Yesterday's PR #13 (feb638e) violated this by routing customer-facing inference paths to opencode + ollama_cloud + openrouter. Reverting the hot-path routes only; cloud providers stay configured in providers.toml for explicit dev-tool opt-in. Reverted: - modes.toml staffing_inference: kimi-k2.6 → qwen3.5:latest (local Ollama) - modes.toml doc_drift_check: gemini-3-flash-preview → qwen3.5:latest - execution_loop overseer: opencode/claude-opus-4-7 → ollama/qwen3.5:latest Was a paid Anthropic call on every overseer escalation; now local + free. Gateway compiles + restarts clean. Lance smoke 10/10. Live providers list unchanged (kimi/ollama_cloud/opencode/openrouter all still CONFIGURED; they just aren't ROUTED to from the staffing inference path anymore). This stops the API meter on customer requests. Cloud providers remain opt-in via explicit provider= caller hint, which the scrum tool + auditor pipeline + bot/propose use deliberately.

root	e9d17f7d5a	sanitize: drop over-broad path-missing branch + UTF-8-safe redaction ... Re-scrum of yesterday's sanitizer fix surfaced 2 more real bugs in the fix itself (opus, both WARN, neither caught by kimi/qwen): W1 (service.rs:1949) — `mentions_path_missing` standalone branch was too aggressive. A registry-internal error like "/root/.cargo/.../x.rs: no such file or directory" would 404 because it triggers without dataset context. That's a real 500. Dropped the standalone branch; require dataset context AND missing-shape phrase. Lance's actual "Dataset at path X was not found" still satisfies it. W2 (service.rs:2018) — `out.push(bytes[i] as char)` corrupted multi-byte UTF-8 by casting raw bytes to char (only sound for ASCII < 128). A path containing user-supplied non-ASCII names produced Latin-1 mojibake. Rewrote redact_paths to track byte indices and emit unmatched runs as &str slices via push_str(&s[range]) — preserves multi-byte sequences verbatim. Step advance is now per-char, not per-byte, via small utf8_char_len helper. Two new regression tests: - is_not_found_does_not_match_unrelated_path_missing - redact_preserves_multibyte_utf8 (uses 工作 + café in input) 12/12 sanitize tests PASS. Smoke 10/10 PASS.

root	ac7c996596	sweep up scrum WARNs — model const, stale config, temp_path entropy, smoke gate ... Four findings deferred from the 2026-05-02 scrum, all 1-5 line fixes: W1 (kimi WARN @ scrum_master_pipeline.ts:1143) — `gemini-3-flash-preview` hardcoded twice in MAP and REDUCE phases. Extracted TREE_SPLIT_MODEL + TREE_SPLIT_PROVIDER constants near the existing config block. Diverging the two would break tree-split coherence (per-shard digests must come from the same model the reducer collapses). W2 (qwen WARN @ providers.toml:30) — stale `kimi-k2:1t` reference in operator-facing comments after PR #13 noted it's upstream-broken. Reframed as historical context ("was X here pre-2026-05-03 — that model is broken") so future operators don't paste-route from the comment. W3 (opus WARN @ vectord-lance/src/lib.rs:622) — temp_path() entropy was only pid+nanos, which collide under tokio scheduling when multiple tests in the same cargo process create temp dirs back-to-back. Added per-process AtomicU64 sequence counter — guarantees uniqueness regardless of clock. W4 (opus INFO @ scripts/lance_smoke.sh:38) — `|| echo '{}'` swallowed curl transport failures (gateway down, network broken, timeout), surfacing as misleading "no method field" jq errors at the next probe. Now captures $? separately, gates a "curl reachable" probe, and only falls back to empty body for the dependent jq parse. Smoke went 9 → 10 probes. Verified: vectord-lance 7/7 tests PASS, gateway cargo check clean, lance_smoke.sh 10/10 PASS against live gateway.

root	7bb66f08c3	lance: scrum-driven sanitizer + smoke-gate fixes (opus 2026-05-02 BLOCK) ... Cross-lineage scrum on the lance wave (4 bundles, 33 distinct findings) surfaced 1 real BLOCK and 2 real WARNs from opus that the kimi/qwen lineages missed. Per feedback_cross_lineage_review.md, opus is the load-bearing reviewer; cross-lineage convergence is noise unless verified. BLOCK fix — sanitize_lance_err path-stripping was unsound: err.split("/home/").next().unwrap_or(&err) returns Some("") when err STARTS with "/home/", erasing the entire message. Replaced truncation with redact_paths() — a hand-rolled scanner that walks the input once, replacing path-shaped substrings with [REDACTED] while preserving surrounding error context. Catches: - absolute paths under /root/.cargo, /home, /var, /tmp, /etc, /usr, /opt - relative variants (Lance occasionally strips leading slash — observed live "Dataset at path home/profit/lakehouse/data/lance/x was not found") - multiple occurrences in one error - preserves quote/comma/whitespace terminators WARN fix #1 — is_not_found heuristic was too broad: lower.contains("not found") caught real 500s like "column not found", "field not found in schema". Narrowed to require dataset-shape phrasing AND exclude the column/field/schema patterns explicitly. WARN fix #2 — lance_smoke.sh `grep -qvE` was an unsound regression gate. bash -c "echo '$BODY' | grep -qvE 'pat'" With -v -q, exits 0 if ANY line lacks the pattern — so a multi-line body with one leak line + any clean line FALSE-PASSES. Replaced with the correct "pattern absent" form: `! grep -qE 'pat'`. Also expanded the pattern set (added /var/, /tmp/) since the scrum surfaced these as additional leak vectors. Also unblocks pre-existing pathway_memory test compile error (stale PathwayTrace init missing 6 Mem0-versioning fields added in 6ac7f61). Tests filled in with sensible defaults — needed to run sanitize_tests. 10/10 new sanitize tests pass. Smoke 9/9 PASS against rebuilt+restarted gateway. Live missing-index probe now returns: "lance dataset not found: no-such-11205" + HTTP 404 (was: leaked absolute paths + HTTP 500 → leaked absolute and relative paths post-first-fix → clean message + 404 now.)

root	044650a1da	lance-bench: also build doc_id btree post-IVF — match gateway's migrate behavior ... The bench's own measure_random_access_lance uses take(row_position) — doesn't need the btree. But datasets written by this bench are commonly queried via /vectors/lance/doc/<name>/<doc_id> downstream, and without the btree that path falls back to a full table scan. Building inline keeps bench-produced datasets immediately production-shape and removes a footgun (the same one that made scale_test_10m's doc-fetch ~100ms until commit 5d30b3d fixed it via the migrate handler path).

root	5d30b3da89	lance: auto-build doc_id btree in migrate handler (root-cause for 10M doc-fetch slowness) ... scale_test_10m doc-fetch p50 was ~100ms — full table scan over 35GB. Root cause: the auto-build at service.rs:1492-1503 only fires for IndexMeta- registered indexes during set_active_profile warming. lance-bench writes datasets through /vectors/lance/migrate/* directly, bypassing IndexMeta, so its datasets never get the doc_id btree that ADR-019 depends on. Fix: build the btree inline at the end of lance_migrate. Costs ~1.2s on 10M rows (+269MB on disk), drops doc-fetch from ~100ms to ~5ms (20x). Failure is non-fatal — logs a warning and the dataset stays queryable. Verified live (post-restart): scale_test_10m doc-fetch 4-15ms across 5 calls, smoke 9/9 PASS, vectord-lance 7/7 unit tests PASS.

root	7594725c25	lance backend: 4-pack — bug fix + smoke + tests + 10M re-bench ... Surfaced by the 2026-05-02 audit (vectord-lance + lance-bench + glue existed and worked but had no tests, no smoke, leaked server paths on missing-index search, and the ADR-019 10M re-bench was deferred). ## 1. Fix: missing-index search returned 500 + leaked filesystem path Pre-fix: $ POST /vectors/lance/search/no-such-index HTTP 500 Dataset at path home/profit/lakehouse/data/lance/no-such-index was not found: Not found: home/profit/lakehouse/data/lance/no-such-index/ _versions, /root/.cargo/registry/src/index.crates.io-...-1949cf8c.../ lance-table-4.0.0/src/io/commit.rs:364:26, ... Post-fix: HTTP 404 lance dataset not found: no-such-index Added `sanitize_lance_err()` in crates/vectord/src/service.rs that: - maps "not found" / "no such file" patterns → 404 (was 500) - strips /home/ and /root/.cargo/ paths from any error body Applied to all 5 lance handlers: search, get_doc, build_index, append, migrate. The store_for() handle is cheap-and-stateless; the actual disk hit happens inside the operation, which is where the leak originated. ## 2. scripts/lance_smoke.sh — first regression gate 9-probe smoke against the live HTTP surface. Exercises only read paths (no state mutation in CI). Specifically locks the sanitizer fix — a future regression that re-introduces the path leak fires the smoke immediately. 9/9 PASS against the live :3100 today. ## 3. Unit tests on vectord-lance/src/lib.rs (was: zero tests) 7 tests covering the public LanceVectorStore API: - fresh_store_reports_no_state — handle is lazy - migrate_then_count_and_fetch — Parquet → Lance round-trip - get_by_doc_id_missing_returns_none — Ok(None) vs Err contract that lets the HTTP handler return 404 cleanly - append_grows_count_and_new_rows_fetchable — ADR-019's structural-difference claim verified at the unit level - append_dim_mismatch_errors — guards against silently breaking search by accepting inconsistent-dim rows - search_returns_nearest — exact-vector match → top-1 - stats_reports_post_migrate_state — locks the field shape 7/7 PASS. cargo test -p vectord-lance --lib green. ## 4. 10M re-bench (deferred from ADR-019) reports/lance_10m_rebench_2026-05-02.md captures the numbers driven against the live :3100 over data/lance/scale_test_10m (33GB / 10M vectors, IVF_PQ confirmed via response method tag). Headline: Search cold (10 diverse queries): median ~32ms, mean ~46ms Search warm (5x same query): ~20ms p50 Doc fetch (5x same id): ~100ms p50 Search latency at 10M is acceptable for batch / async workloads, too slow for sub-10ms voice/recommendation paths. ADR-019's "Lance pulls ahead at 10M" claim remains unverified-but-not-refuted — at this scale HNSW doesn't operationally exist (10M × 768d × 4 bytes = 30GB just for vectors). Real finding: doc-fetch at 10M is 300x slower than the 100K number ADR-019 cited (311μs → ~100ms). Likely cause: scalar btree index on doc_id may not be built for this dataset. Follow-up to investigate whether forcing build_scalar_index brings it back to the load-bearing O(1) range. Captured in the report.

root	98b6647f2a	gateway: IterateResponse echoes trace_id + enable session_log_path ... Closes the 2026-05-02 cross-runtime parity gap: Go's validator.IterateResponse carried trace_id back to callers; Rust's didn't. A caller pivoting from response → Langfuse → session log worked on Go but failed on Rust because the join key wasn't visible in the response body. ## Changes crates/gateway/src/v1/iterate.rs: - IterateResponse + IterateFailure gain `trace_id: Option<String>` (skip-serializing-if-none preserves backward-compat for any consumer parsing the response without the field) - Both return sites populated with the resolved trace_id lakehouse.toml: - [gateway].session_log_path set to /tmp/lakehouse-validator/sessions.jsonl — same path Go validatord writes to. The two daemons now co-write one unified longitudinal log; rows tag daemon="gateway" vs daemon="validatord" so producers stay distinguishable in DuckDB queries. Append-write is atomic at the row sizes both runtimes produce, so concurrent writes from both daemons are safe. ## Verification Post-restart of lakehouse.service: POST /v1/iterate with X-Lakehouse-Trace-Id: rust-fix1-test → response.trace_id = "rust-fix1-test" ✓ (was: field absent) → sessions.jsonl latest row daemon=gateway, session_id=rust-fix1-test ✓ (was: no row) Cross-runtime drive — same prompt to Rust :3100 and Go :4110: Rust: trace_id=unified-rust-001, daemon=gateway, accepted Go: trace_id=unified-go-001, daemon=validatord, accepted Same file, distinct daemons, one query covers both: SELECT daemon, COUNT(*) FROM read_json_auto('sessions.jsonl', format='nd') GROUP BY daemon → gateway: 2, validatord: 19 All 4 parity probes still 6/6 + 12/12 + 4/4 + 2/2 against live :3100 + :4110 stacks. Cargo test 4/4 PASS for v1::iterate module. ## Architecture invariant The "unified longitudinal log" thesis is now demonstrated. Operators running both runtimes in production point both daemons at the same session_log_path and DuckDB queries naturally span both producers.

root	57bde63a06	gateway: trace-id propagation + coordinator session JSONL (Rust parity) ... Cross-runtime parity with the Go-side observability wave (commits d6d2fdf + 1a3a82a in golangLAKEHOUSE). The two layers J flagged: the LIVE per-call view (Langfuse) and the LONGITUDINAL forensic view (JSONL queryable via DuckDB). Hard correctness gate (FillValidator phantom-rejection) was already in place; this is the observability on top. ## Trace-id propagation X-Lakehouse-Trace-Id header constant declared in crates/gateway/src/v1/iterate.rs (matches Go's shared.TraceIDHeader byte-for-byte). When set on an inbound /v1/iterate request, the handler reuses it; the chat + validate self-loopback hops forward the same header so chatd's trace emit nests under the parent rather than minting a fresh top-level trace per call. ChatTrace gains a parent_trace_id field. emit_chat_inner skips the trace-create event when parent is set, only emits the generation-create which attaches to the existing trace tree. Result: an iterate session with N retries shows in Langfuse as ONE tree, not N+1 disconnected traces. emit_attempt_span (new) writes one Langfuse span per iteration attempt with input={iteration, model, provider, prompt} and output={verdict, raw, error}. WARNING level on non-accepted verdicts. The returned span id is stamped on the corresponding SessionRecord attempt for cross-log correlation. ## Coordinator session JSONL crates/gateway/src/v1/session_log.rs — new writer matching Go's internal/validator/session_log.go schema byte-for-byte: - SessionRecord with schema=session.iterate.v1 - SessionAttemptRecord per retry - SessionLogger.append: tokio Mutex serialized append-only - Best-effort posture (slog.Warn on error, never blocks request) iterate.rs builds + appends a row on EVERY code path: - accepted: write_session_accepted with grounded_in_roster bool derived from validate_workers WorkerLookup (matches Go's handlers.rosterCheckFor("fill") semantics) - max-iter-exhausted: write_session_failure - infra-error: write_infra_error (so a missing /v1/iterate event never silently disappears from the longitudinal log) [gateway].session_log_path config field (empty = disabled). Production: /var/lib/lakehouse/gateway/sessions.jsonl. Operators who want a unified longitudinal stream can point both Rust and Go loggers at the same path — write-append is safe at the row sizes we produce. ## Cross-runtime parity probe crates/gateway/src/bin/parity_session_log: tiny stdin/stdout helper that round-trips a fixture through SessionRecord serde. golangLAKEHOUSE/scripts/cutover/parity/session_log_parity.sh feeds 4 fixtures through both helpers and diffs the rows after stripping timestamp + daemon (the two fields that legitimately differ between producers). Result: **4/4 byte-equal** including the unicode-prompt fixture ("Café résumé ⭐ 你好"). Schema parity holds. The non-trivial-equal guard in the probe rejects the case where both sides fail identically — protecting against a regression where one side silently stops producing valid JSON. ## Verification - cargo test -p gateway --lib: 90/90 PASS (3 new session_log tests including concurrent-append safety) - cargo check --workspace: clean - session_log_parity.sh: 4/4 fixtures byte-equal - Both runtimes can append to the same path; DuckDB sees one stream - The Go-side validatord smoke remains 5/5 (unchanged) ## Architecture invariant Don't propose to "wire trace-id propagation in Rust" or "add Rust session log" — both are now shipped on the demo/post-pr11-polish branch. The longitudinal log + Langfuse tree together cover the multi-call observability concern J flagged 2026-05-02.

root	ba928b1d64	aibridge: drop Python sidecar from hot path; AiClient → direct Ollama ... The "drop Python sidecar from Rust aibridge" item from the architecture_comparison decisions tracker. Universal-win cleanup — removes 1 process + 1 runtime + 1 hop from every embed/generate request, with no behavior change. ## What was on the hot path before gateway → AiClient → http://:3200 (FastAPI sidecar) ├── embed.py → http://:11434 (Ollama) ├── generate.py → http://:11434 ├── rerank.py → http://:11434 (loops generate) └── admin.py → http://:11434 (/api/ps + nvidia-smi) The sidecar's hot-path code (~120 LOC across embed.py / generate.py / rerank.py / admin.py) was pure pass-through: each route translated its request body to Ollama's wire format and returned Ollama's response in a sidecar envelope. Zero logic, one full HTTP hop of overhead. ## What's on the hot path now gateway → AiClient → http://:11434 (Ollama directly) Inline rewrites in crates/aibridge/src/client.rs: - embed_uncached: per-text loop to /api/embed; computes dimension from response[0].length (matches the sidecar's prior shape) - generate (direct path): translates GenerateRequest → /api/generate (model, prompt, stream:false, options:{temperature, num_predict}, system, think); maps response → GenerateResponse using Ollama's field names (response, prompt_eval_count, eval_count) - rerank: per-doc loop with the same score-prompt the sidecar used; parses leading number, clamps 0-10, sorts desc - unload_model: /api/generate with prompt:"", keep_alive:0 - preload_model: /api/generate with prompt:" ", keep_alive:"5m", num_predict:1 - vram_snapshot: GET /api/ps + std::process::Command nvidia-smi; same envelope shape as the sidecar's /admin/vram so callers keep parsing - health: GET /api/version, wrapped in a sidecar-shaped envelope ({status, ollama_url, ollama_version}) Public AiClient API is unchanged — Request/Response types untouched. Callers (gateway routes, vectord, etc.) require zero updates. ## Config changes - crates/shared/src/config.rs: default_sidecar_url() bumps to :11434. The TOML field stays `[sidecar].url` for migration compat (operators with existing configs don't need to rename anything). - lakehouse.toml + config/providers.toml: bumped to localhost:11434 with comments explaining the 2026-05-02 transition. ## What stays Python sidecar/sidecar/lab_ui.py (385 LOC) + pipeline_lab.py (503 LOC) are dev-mode Streamlit-shape UIs for prompt experimentation. Not on the runtime hot path; continue running for ad-hoc work. The embed/generate/rerank/admin routes inside sidecar can be retired, but operators who want to keep the sidecar process running for the lab UI face no breakage — those routes still call Ollama and work. ## Verification - cargo check --workspace: clean - cargo test -p aibridge --lib: 32/32 PASS - Live smoke against test gateway on :3199 with new config: /ai/embed → 768-dim vector for "forklift operator" ✓ /v1/chat → provider=ollama, model=qwen2.5:latest, content=OK ✓ - nvidia-smi parsing tested via std::process::Command path - Live `lakehouse.service` (port :3100) NOT yet restarted — deploy step is operator-driven (sudo systemctl restart lakehouse.service) ## Architecture comparison update (Captured separately in golangLAKEHOUSE/docs/ARCHITECTURE_COMPARISON.md decisions tracker.) The "drop Python sidecar" line moves from _open_ to DONE. The Rust process model now has 1 mega-binary instead of 1 mega-binary + 1 sidecar process — a small but real reduction in ops surface.

Both runtimes' algorithms are genuinely equivalent. Substrate gate the probe enforces: `cargo test -p gateway extract_json` PASS before any parity comparison runs.

Two load-bearing runtime changes that were never committed: 1. crates/gateway/src/v1/iterate.rs — `state` → `_state` on the unused route-state parameter. Cleared the one cargo workspace warning. Fix was made earlier this session but the working-tree change never made it into a commit. 2. data/_catalog/manifests/564b00ae-cbf3-4efd-aa55-84cdb6d2b0b7.json — DELETED. This was the dead manifest for `client_workerskjkk`, a typo dataset whose parquet was deleted but whose catalog entry stayed registered. Every SQL query failed schema inference on the missing file before reaching its target table — that's the bug that made /system/summary report 0 workers and the demo show zero bench. Deleting the manifest keeps the fix on disk; committing the deletion keeps it in git so a fresh checkout doesn't regress. 3. data/_catalog/manifests/32ee74a0-59b4-4e5b-8edb-70c9347a4bf3.json — runtime catalog metadata update from the successful_playbooks_live write path.

root	6ed48c1a69	gateway+validator: /v1/health reports honest worker count for production ... Adds `fn len() -> usize` (default 0) to the WorkerLookup trait. The InMemoryWorkerLookup overrides with HashMap size; ParquetWorkerLookup constructs an InMemoryWorkerLookup so it inherits the count. /v1/health now reports `workers_count` (exact integer) alongside `workers_loaded` (derived bool: count > 0). The previous placeholder true was a known caveat in the prior commit's body — this closes it. Production switchover use case: J swaps workers_500k.parquet → real Chicago contractor data, restarts the gateway, and verifies the swap with one curl: curl http://localhost:3100/v1/health | jq .workers_count Expected: matches the row count of the new file. Mismatch (or 0) means the file is missing / unreadable / had a schema mismatch and the gateway fell back to the empty InMemoryWorkerLookup. Operator catches the drift before traffic reaches the validators. Verified live (current synthetic data): workers_count: 500000 (matches workers_500k.parquet row count) workers_loaded: true When the Chicago data lands, the same curl is the single source of truth that the new dataset is hot.

root	74ad77211f	gateway: /v1/health — production operational status endpoint ... Adds GET /v1/health that returns a JSON snapshot of subsystem state so operators (and load balancers, and the lakehouse-auditor service) can verify the gateway is fully booted before routing traffic. Phase 42-45 closures are now production-deployable; this endpoint is the canary that proves it. Returns 200 always — fields are observed-state, not pass/fail gates. Monitoring tools evaluate the booleans + counts against their own thresholds. Shape: { "status": "ok", "workers_loaded": bool, "providers_configured": { "ollama_cloud": bool, "openrouter": bool, "kimi": bool, "opencode": bool, "gemini": bool, "claude": bool, }, "langfuse_configured": bool, "usage_total_requests": N, "usage_by_provider": ["ollama_cloud", "openrouter", ...] } Verified live: curl http://localhost:3100/v1/health → 4 providers configured (kimi, ollama_cloud, opencode, openrouter) → 2 not configured (claude, gemini — keys not wired) → langfuse_configured: true → workers_loaded: true (500K-row workers_500k.parquet snapshot) Caveat: workers_loaded is a placeholder true — WorkerLookup trait doesn't have a len() method yet, so we can't honestly report row count from the runtime probe. The boot log line "loaded workers parquet snapshot rows=N" is the source of truth on count. Future follow-up: add `fn len(&self) -> usize` to WorkerLookup so /v1/health can report the exact figure. Pre-production checklist context: J flagged production switchover incoming — synthetic profiles will be replaced with real Chicago data soon. /v1/health gives the operator a single curl to verify the gateway sees the new data after the parquet swap (boot log + this endpoint). Hot-swap reload (POST /v1/admin/reload-workers) deferred to a follow-up — requires V1State.validate_workers to wrap in RwLock or ArcSwap so write traffic doesn't block the steady-state read path.

Phase 45 (doc-drift detection + context7 integration) was mostly already shipped in prior sessions: DocRef struct, doc_drift module, /doc_drift/check + /doc_drift/resolve endpoints, mcp-server's context7_bridge.ts, boost exclusion in compute_boost_for_filtered _with_role. The two missing pieces this commit lands: 1. POST /vectors/playbook_memory/doc_drift/scan — batch scan across ALL active playbooks. Iterates the snapshot, filters out retired + already-flagged + no-doc_refs, runs check_all_refs on the rest, flags drifted entries via PlaybookMemory::flag_doc_drift. 2. Per-detection write to data/_kb/doc_drift_corrections.jsonl. One row per drifted playbook with playbook_id + scanned_at + drifted_tools[] + per_tool[] + recommended_action. Downstream consumers (overview model, operator dashboard, scrum_master prompt enrichment) read this file to surface "this playbook compounded the wrong way" signals to humans. Idempotent by design: - Already-flagged entries with no resolved_at are counted as `already_flagged` and skipped (no double-flag, no duplicate row). - Re-scanning after resolve_doc_drift() unflags an entry brings it back into the eligible set on the next scan. Aggregate response shape: { "scanned": N, // playbooks with doc_refs we checked "newly_flagged": N, // drift detected this scan "already_flagged": N, // skipped (still under review) "skipped_retired": N, "skipped_no_refs": N, // pre-Phase-45 playbooks "drifted_by_tool": {tool: count}, "corrections_written": N, } Verified live: POST /doc_drift/scan → scanned=4, newly_flagged=4, drifted_by_tool={docker:4, terraform:1}, corrections_written=4 POST /doc_drift/scan (re-run) → scanned=0, newly_flagged=0, already_flagged=6 (idempotent) data/_kb/doc_drift_corrections.jsonl → 5 rows total (existing seed + this scan) Phase 45 closure status: DocRef + PlaybookEntry.doc_refs ✅ prior session doc_drift module + check_all_refs ✅ prior session /doc_drift/check + /resolve ✅ prior session mcp-server/context7_bridge.ts ✅ prior session boost exclusion in compute_boost_* ✅ prior session /doc_drift/scan + corrections.jsonl ✅ THIS COMMIT The 0→85% thesis stays valid against external doc drift. Popular playbooks can no longer compound the wrong way as Docker / Terraform / React / etc. patch their docs — the scan flags drift, the boost filter excludes the playbook, the operator reviews the corrections .jsonl, and a revise call (Phase 27) supersedes the stale entry with corrected operation/approach.

root	98db129b8f	gateway: /v1/iterate — Phase 43 v3 part 3 (generate → validate → retry loop) ... Closes the Phase 43 PRD's "iteration loop with validation in place" structurally. Single endpoint that wraps the 0→85% pattern any caller can post against without re-implementing it. POST /v1/iterate { "kind":"fill" | "email" | "playbook", "prompt":"...", "system":"...", (optional) "provider":"ollama_cloud", "model":"kimi-k2.6", "context":{...}, (target_count/city/state/role/...) "max_iterations":3, (default 3) "temperature":0.2, (default 0.2) "max_tokens":4096 (default 4096) } → 200 + IterateResponse (artifact accepted) {artifact, validation, iterations, history:[{iteration,raw,status}]} → 422 + IterateFailure (max iter reached) {error, iterations, history} The loop: 1. Generate via gateway-internal HTTP loopback to /v1/chat with the given provider/model. Model output is the model's free-form text. 2. Extract a JSON object from the output — handles fenced blocks (```json ... ```), bare braces, and prose-with-embedded-JSON. On no extractable JSON: append "your response wasn't valid JSON" to the prompt and retry. 3. POST the extracted artifact to /v1/validate (server-side reuse of the FillValidator/EmailValidator/PlaybookValidator stack from Phase 43 v3 part 2). 4. On 200 + Report: success — return artifact + history. 5. On 422 + ValidationError: append the specific error JSON to the prompt as corrective context and retry. This is the "observer correction" piece in PRD shape, simplified — the validator's own structured error IS the feedback signal. 6. Cap at max_iterations. Verified end-to-end with kimi-k2.6 via ollama_cloud: Request: fill 1 Welder in Toledo, model picks W-1 (actually Louisville, KY — wrong city) iter 0: model emits {fills:[W-1,"W-1"]} → 422 Consistency ("city 'Louisville' doesn't match contract city 'Toledo'") iter 1: prompt now includes the error → model emits same answer (didn't pick a different worker — model lacks roster access; would need hybrid_search upstream) max=2: 422 IterateFailure with full history The negative test demonstrates the LOOP MECHANICS work: - Generation → validation → retry-with-error-context → cap - The model's failure trace is queryable; downstream tooling can inspect history[] to see exactly where each iteration broke - A production executor would do hybrid_search to find Toledo workers before posting; /v1/iterate is the validation+retry layer downstream JSON extractor handles three shapes: - Fenced: ```json {...} ``` (preferred — explicit signal) - Bare: plain text + {...} + plain text - Multi: picks the first balanced {...} Unit tests cover all three plus the no-JSON fallback. Phase 43 closure status: v1: scaffolds ✅ (older commit) v2: real validators ✅ 00c8408 v3 part 1: parquet WorkerLookup ✅ ebd9ab7 v3 part 2: /v1/validate ✅ 86123fc v3 part 3: /v1/iterate ✅ THIS COMMIT The "0→85% with iteration" thesis is now testable in production. Staffing executors can compose hybrid_search → /v1/iterate (with validation) and converge on validation-passing artifacts in 1-2 iterations on average.

root	5d93a715c3	gateway: Phase 44 part 3 — split AiClient so vectord routes through /v1/chat ... Builds two AiClient instances at boot: - `ai_client_direct = AiClient::new(sidecar_url)` — direct sidecar transport. Used by V1State (gateway's own /v1/chat ollama_arm needs this — calling /v1/chat from itself would self-loop) and by the legacy /ai proxy. - `ai_client_observable = AiClient::new_with_gateway(sidecar_url, ${gateway_host}:${gateway_port})` — routes generate() through /v1/chat with provider="ollama". Used by: vectord::agent (autotune background loop) vectord::service (the /vectors HTTP surface — RAG, summary, playbook synthesis, etc.) Net result: every LLM call from a vectord module now lands in /v1/usage and Langfuse traces. The autotune agent's hourly cycle becomes observable; /vectors RAG calls show provider+model+latency in the usage report. Phase 44 PRD's gate ("/v1/usage accounts for every LLM call in the system within a 1-minute window") is now satisfied for the gateway-hosted services. Cost: one localhost HTTP hop per vectord-originated LLM call. At ~1-3ms RTT for in-process loopback, negligible against the LLM call's own 30-90s wall-clock. Phase 44 part 4 (deferred): - Standalone consumers that build their own AiClient (test harnesses, bot/propose, etc) — the TS-side already migrated in part 1 + the regression guard at scripts/check_phase44_callers.sh catches new direct callers. Rust standalone harnesses (if any surface) follow the same pattern: construct via new_with_gateway to opt into observability. - Direct sidecar callers in standalone tools (scripts/serve_lab.py is one) — Python-side; out of Rust scope. Verified: cargo build --release -p gateway compiles systemctl restart lakehouse active /v1/chat sanity PONG, finish=stop When the autotune agent next cycles or any /vectors RAG endpoint fires, /v1/usage will show the provider=ollama tick — first real-world data should land within the next agent cycle.

root	7b88fb9269	aibridge: Phase 44 part 2 — opt-in /v1/chat routing for AiClient.generate() ... The Phase 44 PRD's "AiClient becomes a thin /v1/chat client" was a chicken-and-egg problem: the gateway's own /v1/chat ollama_arm calls AiClient.generate() to reach the sidecar. If AiClient unconditionally routed through /v1/chat, gateway → /v1/chat → ollama → AiClient → /v1/chat would loop forever. Solution: opt-in routing. - `AiClient::new(base_url)` — direct-sidecar, gateway-internal use (gateway's own /v1/chat handlers, ollama::chat in mod.rs) - `AiClient::new_with_gateway(base_url, gateway_url)` — routes generate() through ${gateway_url}/v1/chat with provider="ollama" so the call lands in /v1/usage + Langfuse traces Shape translation in generate_via_gateway(): GenerateRequest {prompt, system, model, temperature, max_tokens, think} → /v1/chat {messages: [system?, user], provider:"ollama", ...} /v1/chat response choices[0].message.content + usage.{prompt,completion}_tokens → GenerateResponse {text, model, tokens_evaluated, tokens_generated} embed(), rerank(), and admin methods (health, unload_model, etc.) stay direct-to-sidecar — no /v1/embed equivalent yet, no point round-trip. Transitive migration: aibridge::continuation::generate_continuable goes through TextGenerator::generate_text() → AiClient.generate(), so every caller of generate_continuable inherits the routing decision made at AiClient construction. Phase 21's continuation loop, hot- path JSON emitters, etc. all gain observability for free when the construction site opts in. Verified end-to-end: curl /v1/chat with the exact JSON shape AiClient sends → "PONG-AIBRIDGE", finish=stop, 27/7 tokens /v1/usage after the call → requests=1, by_provider.ollama.requests=1, tokens tracked Phase 44 part 3 (next): - Migrate vectord's AiClient construction site so vectord modules (rag, autotune, harness, refresh, supervisor, playbook_memory) flow through /v1/chat. Currently the gateway's main.rs constructs one AiClient via `new()` and shares it via V1State; vectord inherits direct-sidecar transport. Migration requires constructing a SEPARATE AiClient with `new_with_gateway` for vectord's state bag (V1State.ai_client must stay direct to avoid the self-loop).

root	86123fce4c	gateway: /v1/validate endpoint — Phase 43 v3 part 2 ... Closes the Phase 43 PRD's "any caller can validate" surface. The validator crate (FillValidator + EmailValidator + PlaybookValidator + WorkerLookup) is now reachable over HTTP at /v1/validate. Request/response: POST /v1/validate {"kind":"fill"|"email"|"playbook", "artifact":{...}, "context":{...}?} → 200 + Report on success → 422 + ValidationError on validation failure → 400 on bad kind Boot-time wiring (main.rs): - Load workers_500k.parquet into a shared Arc<dyn WorkerLookup> - Path overridable via LH_WORKERS_PARQUET env - Missing file: warn + fall back to empty InMemoryWorkerLookup so the endpoint stays live (validators just fail Consistency on every worker-existence check, which is the correct behavior when the roster isn't configured) - Boot log line: "workers parquet loaded from <path>" or "workers parquet at <path> not found" - Live boot timing: 500K rows loaded in ~1.4s V1State gains `validate_workers: Arc<dyn validator::WorkerLookup>`. The `_context` JSON key is auto-injected from `request.context` so callers can either embed `_context` directly in `artifact` or split it cleanly via the `context` field. Verified live (gateway + 500K worker snapshot): POST {kind:"fill", phantom W-FAKE-99999} → 422 Consistency ("does not exist in worker roster") POST {kind:"fill", real W-1, "Anyone"} → 200 OK + Warning ("differs from roster name 'Donald Green'") POST {kind:"email", body has 123-45-6789} → 422 Policy ("SSN- shaped sequence") POST {kind:"nonsense"} → 400 Bad Request The "0→85% with iteration" thesis can now run end-to-end on real staffing data: an executor emits a fill_proposal, posts to /v1/validate, gets a structured ValidationError on phantom IDs or inactive workers, observer-corrects, retries. Closure of that loop in a scrum harness is the next commit (separate scope). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-27 07:40:27 -05:00
root	ebd9ab7c77	validator: Phase 43 v3 — production WorkerLookup backed by workers_500k.parquet ... Closes the Phase 43 v2 loose end. The validator scaffolds (FillValidator, EmailValidator) take Arc<dyn WorkerLookup> at construction; this commit ships the parquet-snapshot impl that production code wires in. Schema mapping (workers_500k.parquet → WorkerRecord): worker_id (int64) → candidate_id = "W-{id}" (matches what the staffing executor emits) name (string) → name (already concatenated upstream) role (string) → role city, state (string) → city, state availability (double) → status: "active" if >0 else "inactive" Workers_500k has no `status` column; we derive from `availability` since 0.0 means vacationing/suspended/etc in this dataset's convention. Once Track A.B's `_safe` view ships with proper status, flip the loader to read it directly — schema mapping is in one function (load_workers_parquet), so the swap is trivial. In-memory snapshot model: - Loads all 500K rows at startup → ~75MB resident - Sync .find() — no per-call I/O on the validation hot path - Refresh = call load_workers_parquet again to rebuild - Caller-driven refresh (no auto-watch) — operators pick the cadence Why workers_500k and not candidates.parquet: candidates.parquet has the right shape (string candidate_id, status, first/last_name) but lacks `role` — and the staffing executor matches the W-* convention from workers_500k_v8 corpus. So the production data path goes through workers_500k. The schema mismatch between the two parquets is documented in `reports/staffing/synthetic-data-gap- report.md` (gap A); resolution is operator's call. Errors are typed (LookupLoadError): - Open: file not found / permission - Parse: invalid parquet - MissingColumn: schema doesn't have required field - BadRow: row missing worker_id or name Schema check happens before iteration, so a wrong-shape file fails loud immediately rather than silently building an empty lookup. Verification: cargo build -p validator compiles cargo test -p validator 33 pass / 0 fail (was 31; +2 for parquet) load_real_workers_500k smoke test passes against the live 500K-row file: W-1 resolves, status + role + city/state all populated. Phase 43 v3 part 2 (next): - /v1/validate gateway endpoint that takes a JSON artifact + dispatches to FillValidator/EmailValidator/PlaybookValidator with a shared WorkerLookup loaded from the parquet at gateway startup. - That closes the "any caller can validate" surface; execution-loop wiring (Phase 43 PRD's "generate → validate → correct → retry") becomes a thin wrapper on top of /v1/validate.

root	454da15301	auditor + aibridge: 6 fixes from Opus 4.7 self-audit on PR #11 ... The kimi_architect auditor on commit 00c8408 ran with auto-promotion to claude-opus-4-7 (diff > 100k chars), produced 10 grounded findings, 1 BLOCK + 6 WARN + 3 INFO. This commit lands 6 of them; 3 are skipped (false positives or out-of-scope cleanup deferred). LANDED: 1. kimi_architect.ts:144 empty-parse cache poisoning. When parseFindings returns 0 findings (markdown shape changed, prompt too big, regex missed every block), the verdict was still persisted with empty findings, and the 24h TTL cache short-circuited every subsequent audit with a useless "0 findings" hit. Fix: only persist when findings.length > 0; metrics still appended unconditionally. 2. kimi_architect.ts:122 outage negative-cache. When callKimi throws (network error, gateway 502, rate limit), we returned skipFinding but didn't note the outage anywhere. Every audit cycle within the 24h TTL hammered the dead upstream. Fix: write a sentinel file `<verdict>.outage` on failure with 10-min TTL; future calls within that window short-circuit immediately. 3. kimi_architect.ts:331 mkdir(join(p, "..")) -> dirname(p). The "/.." idiom resolved correctly via Node path normalization but was non-idiomatic and breaks if the path ever has trailing dots. Both Haiku and Opus self-audits flagged it. 4. inference.ts:202 N=3 consensus latency double/triple-count. `totalLatencyMs += run.latency_ms` summed across THREE parallel `Promise.all` calls — wall-clock is bounded by the slowest, not the sum. Renamed to `maxLatencyMs` using `Math.max`. Telemetry now reports actual wall-clock instead of 3x reality. 5. continuation.rs:198,199,230,231 i64/u64 -> u32 saturating cast. `resp.tokens_evaluated as u32` truncates bits when source > u32::MAX instead of saturating. Fix: u32::try_from(...).unwrap_or(u32::MAX) wraps the cast in a real saturate. Applied to both the empty-retry loop and the structural-completion continuation loop. SKIPPED: - BLOCK at Cargo.lock:8911 "validator-not-in-workspace" — confabulation. The diff Opus saw was truncated mid-line; validator IS in Cargo.toml workspace members. Real-world MAX_DIFF_CHARS=180k edge case to watch as we feed more big diffs. - WARN at kimi_architect.ts:248 regex absolute-path edge case — minor, doesn't affect grounding rate observed so far. - INFO at inference.ts:606 "dead reconstruction loop" — Opus misread. The Promise.all worker fills `summaries[]`; the second loop builds a sequential `scratchpad` string from those. Two distinct operations, not redundant. Verification: bun build auditor/checks/{kimi_architect,inference}.ts compiles cargo check -p aibridge green cargo build --release -p gateway green systemctl restart lakehouse.service lakehouse-auditor.service active Next audit cycle (~90s after push) will run on the new diff and exercise the negative-cache + dirname + maxLatencyMs paths.

root	00c8408335	validator: Phase 43 v2 — real worker-existence + PII + name-consistency checks ... The Phase 43 scaffolds (FillValidator, EmailValidator) shipped with TODO(phase-43 v2) markers for the actual cross-roster checks. This is those checks landing. The PRD calls for "the 0→85% pattern reproduces on real staffing tasks — the iteration loop with validation in place is what made small models successful." Worker-existence is the load-bearing check: when the executor emits {candidate_id: "W-FAKE", name: "Imaginary"}, schema-only validation passes, and only roster lookup catches it. Architecture: - New `WorkerLookup` trait + `WorkerRecord` struct in lib.rs. Sync by design — validators hold an in-memory snapshot, no per-call I/O on the validation hot path. Production wraps a parquet snapshot; tests use `InMemoryWorkerLookup`. - Validators take `Arc<dyn WorkerLookup>` at construction so the same shape covers prod + tests + future devops scaffolds. - Contract metadata travels under JSON `_context` key alongside the validated payload (target_count, city, state, role, client_id for fills; candidate_id for emails). Keeps the Validator trait signature stable and lets the executor serialize context inline. FillValidator (11 tests, was 4): - Schema (existing) - Completeness — endorsed count == target_count - Worker existence — phantom candidate_id fails Consistency - Status — non-active worker fails Consistency - Geo/role match — city/state/role mismatch with contract fails Consistency - Client blacklist — fails Policy - Duplicate candidate_id within one fill — fails Consistency - Name mismatch — Warning (not Error) since recruiters sometimes send roster updates through the proposal layer EmailValidator (11 tests, was 4): - Schema + length (existing) - SSN scan (NNN-NN-NNNN) — fails Policy - Salary disclosure (keyword + $-amount within ~40 chars) — fails Policy. Std-only scan, no regex dep added. - Worker name consistency — when _context.candidate_id resolves, body must contain the worker's first name (Warning if missing) - Phantom candidate_id in _context — fails Consistency - Phone NNN-NNN-NNNN does NOT trip the SSN detector (verified by test); the SSN scanner explicitly rejects sequences embedded in longer digit runs Pre-existing issue (NOT from this change, NOT fixed here): crates/vectord/src/pathway_memory.rs:927 has a stale PathwayTrace struct initializer that fails `cargo check --tests` with E0063 on 6 missing fields. `cargo check --workspace` (production) is green; only the vectord test target is broken. Tracked for a separate fix. Verification: cargo test -p validator 31 pass / 0 fail (was 13) cargo check --workspace green Next: wire `Arc<dyn WorkerLookup>` into the gateway execution loop (generate → validate → observer-correct → retry, bounded by max_iterations=3 per Phase 43 PRD). Production lookup impl loads from a workers parquet snapshot — Track A gap-fix B's `_safe` view is the right source once decided, raw workers_500k otherwise.

One sk-* key reaches 40 models across Anthropic, OpenAI, Google, Moonshot, DeepSeek, Zhipu, Alibaba, Minimax — billed against either the user's Zen balance (pay-per-token premium models) or Go subscription (flat-rate Kimi/GLM/DeepSeek/etc.). The unified /zen/v1 endpoint routes both; upstream picks the billing tier based on model id. Notable adapter quirks: - Strip "opencode/" prefix on outbound (mirrors openrouter/kimi pattern). Caller can use {provider:"opencode", model:"X"} or {model:"opencode/X"}. - Drop temperature for claude-*, gpt-5*, o1/o3/o4 models. Anthropic and OpenAI's reasoning lineage rejects temperature with 400 "deprecated for this model". OCChatBody now serializes temperature as Option<f64> with skip_serializing_if so omitting it produces clean JSON. - max_tokens.filter(|&n| n > 0) catches Some(0) — defensive after the same trap bit kimi.rs (empty env -> Number("") -> 0 -> 503). - 600s default upstream timeout; reasoning models on big audit prompts legitimately take 3-5 min.

root	ff5de76241	auditor + gateway: 2 fixes from kimi_architect's first real run ... Acted on 2 of 10 findings Kimi caught when auditing its own integration on PR #11 head 8d02c7f. Skipped 8 (false positives or out-of-scope). 1. crates/gateway/src/v1/kimi.rs — flatten OpenAI multimodal content array to plain string before forwarding to api.kimi.com. The Kimi coding endpoint is text-only; passing a [{type,text},...] array returns 400. Use Message::text() to concat text-parts and drop non-text. Verified with curl using array-shape content: gateway now returns "PONG-ARRAY" instead of upstream error. 2. auditor/checks/kimi_architect.ts — computeGrounding switched from readFileSync to async readFile inside Promise.all. Doesn't matter at 10 findings; would matter at 100+. Removed unused readFileSync import. Skipped findings (with reason): - drift_report.ts:18 schema bump migration concern: the strict schema_version refusal IS the migration boundary (v1 readers explicitly fail on v2; not a silent corruption risk). - replay.ts:383 ISO timestamp precision: Date.toISOString always emits "YYYY-MM-DDTHH:mm:ss.sssZ" (ms precision). False positive. - mode.rs:1035 matrix_corpus deserializer compat: deserialize_string _or_vec at mode.rs:175 already accepts both shapes. Confabulation from not seeing the deserializer in the input bundle. - /etc/lakehouse/kimi.env world-readable: actually 0600 root. Real concern would be permission-drift; not a code bug. - callKimi response.json hang: obsolete; we use curl now. - parseFindings silent-drop: ergonomic concern, not a bug. - appendMetrics join with "..": works for current path; deferred. - stubFinding dead-type extension: cosmetic. Self-audit grounding rate at v1.0.0: 10/10 file:line citations verified by grep. 2 of 10 actionable bugs landed. The other 8 were correctly flagged as concerns but didn't earn a code change.

root	643dd2d520	gateway: direct Kimi For Coding provider adapter (api.kimi.com) ... Wires kimi-for-coding (Kimi K2.6 underneath) as a first-class /v1/chat provider so consumers can target it via {provider:"kimi"} or model prefix kimi/<model>. Bypasses the upstream-broken kimi-k2:1t on Ollama Cloud and the rate-limited moonshotai/kimi-k2.6 path through OpenRouter. Adapter shape mirrors openrouter.rs (OpenAI-compatible Chat Completions). Differences from generic OpenAI providers: - api.kimi.com is a SEPARATE account system from api.moonshot.ai and api.moonshot.cn. sk-kimi-* keys are NOT interchangeable across them. - Endpoint is User-Agent-gated to "approved" coding agents (Kimi CLI, Claude Code, Roo Code, Kilo Code, ...). Requests from generic clients return 403 access_terminated_error. Adapter sends User-Agent: claude-code/1.0.0. Per Moonshot TOS this is a tampering-class action that may result in seat suspension; J authorized 2026-04-27 with awareness of the risk. - kimi-for-coding is a reasoning model — reasoning_content counts against max_tokens. Default 800-token budget yields empty visible content with finish_reason=length. Code-review workloads need max_tokens >= 1500. - Default 600s upstream timeout (vs 180s for openrouter.rs) — code audits with full file context legitimately take 3-5 minutes. Override via KIMI_TIMEOUT_SECS env. Key handling: - /etc/lakehouse/kimi.env (0600 root) loaded via systemd EnvironmentFile - KIMI_API_KEY env first, then file scrape as fallback - /etc/systemd/system/lakehouse.service NOT included in this commit (system file outside repo); operator must add EnvironmentFile=- /etc/lakehouse/kimi.env to the lakehouse.service unit NOT in scrum_master_pipeline LADDER. The 9-rung ladder is for unattended automatic recovery; placing Kimi there would hammer a TOS-gated endpoint with hostility-policy potential.

Fixes: - mode.rs:1035,1042 matrix_corpus Some/None -> vec![..]/vec![]; cargo check --tests now compiles (was silently broken; only bun tests were running) - scorer.ts:30 SCORER_VERSION env override removed - identical input now produces identical version stamp, not env-dependent drift - transforms.ts:181 auto_apply wall-clock fallback (new Date()) -> deterministic recorded_at fallback - replay.ts:378 recorded_run_id Date.now() -> sha256(recorded_at); replay rows now reproducible given recorded_at - receipts.ts:454,495 input_hash_match hardcoded true was misleading telemetry; bumped DRIFT_REPORT_SCHEMA_VERSION 1->2, field is now boolean|null with honest null when not computed at this layer - score_runs.ts:89-100,159 dedup keyed only on sig_hash made scorer-version bumps invisible. Composite sig_hash:scorer_version forces re-scoring - export_sft.ts:126 (ev as any).contractor bypass emitted "<contractor>" placeholder for every contract_analyses SFT row. Added typed EvidenceRecord.metadata bucket; transforms.ts populates metadata.contractor; exporter reads typed value Verification (all green): cargo check -p gateway --tests compiles bun test tests/distillation/ 145 pass / 0 fail bun acceptance 22/22 invariants bun audit-full 16/16 required checks Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-27 05:34:31 -05:00
root	20a039c379	auditor: rebuild on mode runner + drop tree-split (use distillation substrate) ... Architectural simplification leveraging Phase 5 distillation work: the auditor no longer pre-extracts facts via per-shard summaries because lakehouse_answers_v1 (gold-standard prior PR audits + observer escalations corpus) supplies cross-PR context through the mode runner's matrix retrieval. Same signal, ~50× fewer cloud calls per audit. Per-audit cost: Before: 168 gpt-oss:120b shard summaries + 3 final inference calls After: 3 deepseek-v3.1:671b mode-runner calls (full retrieval included) Wall-clock on PR #11 (1.36MB diff): Before: ~25 minutes After: 88 seconds (3/3 consensus succeeded) Files: auditor/checks/inference.ts - Default MODEL kimi-k2:1t → deepseek-v3.1:671b. kimi-k2 is hitting sustained Ollama Cloud 500 ISE (verified via repeated trivial probes; multi-hour outage). deepseek is the proven drop-in from Phase 5 distillation acceptance testing. - Dropped treeSplitDiff invocation. Diff truncates to MAX_DIFF_CHARS and goes straight to /v1/mode/execute task_class=pr_audit; mode runner pulls cross-PR context from lakehouse_answers_v1 via matrix retrieval. SHARD_MODEL retained for legacy callCloud compatibility (default qwen3-coder:480b if it ever runs). - extractAndPersistFacts now reads from truncated diff (no scratchpad post-tree-split-removal). auditor/checks/static.ts - serde-derived struct exemption (commit 107a682 shipped this; this commit is the rest of the auditor rebuild it landed alongside) - multi-line template literal awareness in isInsideQuotedString — tracks backtick state across lines so todo!() inside docstrings doesn't trip BLOCK_PATTERNS. crates/gateway/src/v1/mode.rs - pr_audit native runner mode added to VALID_MODES + is_native_mode + flags_for_mode + framing_text. PrAudit framing produces strict JSON {claim_verdicts, unflagged_gaps} for the auditor to parse. config/modes.toml - pr_audit task class with default_model=deepseek-v3.1:671b and matrix_corpus=lakehouse_answers_v1. Documents kimi-k2 outage with link to the swap rationale. Real-data audit on PR #11 head 1b433a9 (which is the PR with all the distillation work + auditor rebuild itself): - Pipeline ran to completion (88s for inference; full audit ~3 min) - 3/3 consensus runs succeeded on deepseek-v3.1:671b - 156 findings: 12 block, 23 warn, 121 info - Block findings are legitimate signal: 12 reviewer claims like "Invariants enforced (proven by tests + real run):" that the truncated diff can't directly verify. The auditor is correctly flagging claim-vs-diff divergence — exactly its job. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-26 23:32:44 -05:00
root	d1d97a045b	v1: fire observer /event from /v1/chat alongside Langfuse trace ... Observer at :3800 already collects scrum + scenario events into a ring buffer that pathway-memory + KB consolidation read from. /v1/chat now posts a lightweight {endpoint, source:"v1.chat", input_summary, output_summary, success, duration_ms} event there too — fire-and-forget tokio::spawn, observer-down doesn't block the chat response. Now any tool routed through our gateway (Pi CLI, Archon, openai SDK clients, langchain-js) shows up in the same ring buffer the scrum loop reads, ready for the same KB-consolidation analysis. Independent of the existing langfuse-bridge that polls Langfuse — this path is immediate. Verified: GET /stats shows {by_source: {v1.chat: N}} grows by 1 per chat call, both for direct curl and for Pi CLI invocations.

root	540a9a27ee	v1: accept OpenAI multimodal content shape (array-of-parts) ... Modern OpenAI clients (pi-ai, openai SDK 6.x, langchain-js, the official agents) send `messages[].content` as an array of content parts: `[{type:"text", text:"..."}, {type:"image_url", ...}]`. Our gateway typed `content` as plain `String` and 422'd those calls. Fix: `Message.content` is now `serde_json::Value` so requests deserialize regardless of shape. `Message::text()` flattens content-parts arrays (concat'd `text` fields, non-text parts skipped) for places that need a plain string — Ollama prompt assembly, char counts, the assistant's own response synthesis. `Message::new_text()` constructs string-content messages without writing the wrapper at each call site. Forwarders (openrouter) clone content through verbatim so providers see exactly what the client sent. Verified end-to-end: Pi CLI (`pi --print --provider openrouter`) landed a clean 1902-token request through `/v1/chat/completions`, routed to OpenRouter as `openai/gpt-oss-120b:free`, response in 1.62s, Langfuse trace `v1.chat:openrouter` recorded with provider tag. Same path that any tool using the official openai SDK takes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-26 17:56:46 -05:00
root	3a0b37ed93	v1: OpenAI-compat alias + smart provider routing — gateway is now drop-in middleware ... /v1/chat/completions route alias (same handler as /chat) lets any tool using the official `openai` SDK adopt the gateway via OPENAI_BASE_URL alone — no custom provider field needed. resolve_provider() extended: - bare `vendor/model` (slash) → openrouter (catches x-ai/grok-4.1-fast, moonshotai/kimi-k2, deepseek/deepseek-v4-flash, openai/gpt-oss-120b:free) - bare vendor model names (no slash, no colon) get auto-prefixed: gpt-* / o1-* / o3-* / o4-* → openai/<name> (OpenRouter form) claude-* → anthropic/<name> grok-* → x-ai/<name> Then routed to openrouter. Ollama models (with colon, no slash) keep default routing. Tools like pi-ai validate against an OpenAI-style catalog and send bare names — this lets them flow through cleanly. Verified end-to-end: - curl POST /v1/chat/completions {model: "gpt-4o-mini", ...} → 200, routed to openrouter as openai/gpt-4o-mini - openai SDK with baseURL=http://localhost:3100/v1 → 3 model variants all succeed (openai/gpt-4o-mini, gpt-4o-mini, x-ai/grok-4.1-fast) - Langfuse traces fire automatically on every call (v1.chat:openrouter, provider tagged in metadata) scripts/mode_pass5_variance_paid.ts gains LH_CONDITIONS env so subset runs (e.g. just isolation vs composed) take half the latency. Archon-on-Lakehouse integration: gateway side is done. Pi-ai's openai-responses backend uses /v1/responses (not /chat/completions) and its openrouter backend appears to bail in client-side validation before sending. Patching Pi locally to override baseUrl works for arch but the harness still rejects — needs more work in a follow-up. Direct openai SDK path (langchain-js / agents / patched Pi) works today.

root	7c47734287	v1/mode: parameterized runner + 5 enrichment-experiment modes ... J's directive (2026-04-26): "Create different modes so we can really dial in the architecture before it gets further along — pinpoint the failures and strengths equally so I know what direction to go in. Loop theater happens when we don't pinpoint the most accurate path." Refactored execute() to switch on mode name → EnrichmentFlags preset. Five native modes designed as deliberate experiments — each isolates one architectural axis so the comparison matrix reads off what's doing work vs what's adding latency for nothing: codereview_lakehouse — all enrichment on (ceiling) codereview_null — raw file + generic prompt (baseline) codereview_isolation — file + pathway only (no matrix) codereview_matrix_only — file + matrix only (no pathway) codereview_playbook_only — pathway only, NO file content (lossy ceiling) Each call appends a row to data/_kb/mode_experiments.jsonl with full sources + response. LH_MODE_LOG_OFF=1 to suppress. scripts/mode_experiment.ts — sweeps files × modes serially, prints live progress with per-call enrichment stats. Defaults to OpenRouter free model so cloud quota doesn't gate experiments. scripts/mode_compare.ts — reads the JSONL, outputs per-file matrix + per-mode aggregate + mode-vs-baseline win/loss with avg finding delta. Heuristic finding-count from markdown table rows; pathway citation count from preamble references. scrum_master_pipeline.ts gets a mode-runner fast path gated by LH_USE_MODE_RUNNER=1: try /v1/mode/execute first, fall through to the existing ladder if response < LH_MODE_MIN_CHARS (default 2000) or anything errors. Off by default until A/B-validated. First experiment results (2 files × 5 modes via gpt-oss-120b:free): - codereview_null produces 12.6KB response with ZERO findings (proves adversarial framing is load-bearing) - codereview_playbook_only produces MORE findings than lakehouse on average (12 vs 9) at 73% the latency — pathway memory is the dominant signal driver - codereview_matrix_only underperforms isolation by ~0.5 findings while costing the same latency — matrix corpus likely underperforming for scrum_review task class Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-26 01:36:42 -05:00

J's framing (2026-04-26): "Modes are how you ask ONCE and get BETTER information — they mold the data, hyperfocus the prompt on this codebase's needs, so the model gets it right the first time without the cascading retry ladder." Built the first concrete native enrichment runner (codereview_lakehouse) that composes every context primitive the gateway exposes: 1. Focus file content (read from disk OR caller-supplied) 2. Pathway memory bug_fingerprints for this file area (ADR-021 preamble — "📚 BUGS PREVIOUSLY FOUND IN THIS FILE AREA") 3. Matrix corpus search via the task_class's matrix_corpus 4. Relevance filter (observer /relevance) drops adjacency pollution 5. Assembles ONE precise prompt with system framing 6. Single call to /v1/chat with the recommended model POST /v1/mode/execute dispatches. Native mode → runs the composer. Non-native mode → 501 NOT_IMPLEMENTED with hint (proxy to LLM Team /api/run is queued).

root	d277efbfd2	v1/mode: task_class → mode/model router (decision-only, phase 1) ... HANDOVER §queued (2026-04-25): "Mode router — port LLM Team multi-model patterns. Pick the right TOOL/MODE for each task class via the matrix, not cascade through models." Two-stage architecture: 1. Decision (POST /v1/mode) — pure recommendation, no execution. Returns {mode, model, decision: {source, fallbacks, matrix_corpus, notes}} so callers see WHY this mode was picked. 2. Execution (future POST /v1/mode/execute) — proxy to LLM Team /api/run for modes not yet ported to native Rust runners. Not wired in this phase. Splitting decision from execution lets us A/B-test the routing logic without committing to running every recommendation. The decision function is pure enough for exhaustive unit tests (3 added). config/modes.toml — initial map for 5 task_classes (scrum_review, contract_analysis, staffing_inference, fact_extract, doc_drift_check) + a default. matrix_corpus per task is reserved for the future matrix-informed routing pass. VALID_MODES list (24 modes) is kept in sync manually with LLM Team's /api/run handler at /root/llm_team_ui.py:10581. Adding a mode here without adding it upstream returns 400 from a future proxy. GET /v1/mode/list — operator introspection so a UI can render the registry table without re-parsing TOML. Live-tested: 5 task classes match, unknown classes fall through to default, force_mode override works + validates, bogus modes return 400 with the valid_modes list. Updates reference_llm_team_modes.md memory — earlier note claiming "only extract is registered" was wrong (all 25 are registered).

root	626f18d491	pathway_memory: audit-consensus → retire wire ... When observer's hand-review explicitly rejects the output of a hot-swap-recommended model, the matrix's recommendation was wrong for this context. Auto-retire the trace so future agents don't get the same poisoned recommendation in their preamble. crates/vectord/src/pathway_memory.rs — add `trace_uid` to HotSwapCandidate response and populate from the matched trace. This gives consumers single-trace precision for /pathway/retire. tests/real-world/scrum_master_pipeline.ts: - HotSwapCandidate interface gains trace_uid - new retirePathwayTrace() helper (fire-and-forget, fall-open) - in the obsVerdict reject branch: if hotSwap was active AND the rejected model is the hot-swap-recommended one AND observer confidence ≥0.7, fire retire and null hotSwap so post-loop replay bookkeeping doesn't double-process. - hotSwap declared `let` (was const) so it can be nulled Cycle verdicts ("needs different angle") don't trigger retire — only outright rejects do. Confidence gate avoids retiring on heuristic-fallback verdicts that come back without a confidence number. Closes the "audit-consensus → retire" item from HANDOVER.md.
