Closes the cycle J asked for: curated cloud output lands structured
knowledge in the KB so future audits have architectural context, not
just a log of per-finding signatures.
Three pieces:
1. Inference curation (tree-split) — when diff > 30KB, shard at 4.5KB,
summarize each shard via cloud (temp=0, think=false on small
shards; think=true on main call). Merge into scratchpad. The cloud
verification then runs against the scratchpad, not truncated raw.
Eliminates the 40KB MAX_DIFF_CHARS truncation path for large PRs
(PR #8 is 102KB — was losing 62KB). Anti-false-positive guard in
the prompt: cloud is told scratchpad absence is NOT diff absence,
so it doesn't flag curated-out symbols as missing. unflagged_gaps
section is dropped entirely when curated (scratchpad can't ground
them).
2. fact_extractor — TS client for llm_team_ui's extract-facts mode at
localhost:5000/api/run. Sends curated scratchpad through qwen2.5
extractor + gemma2 verifier, parses SSE stream, returns structured
{facts, entities, relationships, verification, llm_team_run_id}.
Best-effort: if llm_team is down, extraction fails silently and
the audit still completes. AWAITED so CLI tools (audit_one.ts)
don't exit before extraction lands — the systemd poller has 90s
headroom so the extra ~15s doesn't matter.
3. audit_facts.jsonl + checkAuditFacts() — one row per curated audit
with the extraction result. kb_query tails the jsonl, explodes
entity rows, aggregates by entity name with distinct-PR counting,
surfaces entities recurring in 2+ PRs as info findings. Filters
out short names (<3 chars, extractor truncation artifacts) and
generic types (string/number/etc.) so signal isn't drowned.
Verified end-to-end on PR #8: 102KB diff → 23 shards → 1KB scratchpad
→ qwen2.5 extracted 4 facts + 6 entities + 6 relationships (real
code-level knowledge: AggregateOptions<T> type, aggregate<T> async
function with real signature, typed relationships). llm_team_run_id
cross-references to llm_team's own team_runs table.
Also: audit.ts passes (pr_number, head_sha) as InferenceContext so
extracted facts are scope-tagged for the KB index.
The previous Level 1 commit set think=false which broke the cloud
inference check on real PR audits. gpt-oss:120b is a reasoning model;
at think=false on large prompts (40KB diff + 14 claims) it returned
empty content — verified by inspecting verdict 8-8e4ebbe4b38a which
showed "cloud returned unparseable output — skipped" with 13421
tokens used and head:<empty>.
Small-prompt tests passed because the model could respond without
needing to think. Real audits with the full diff + claims context
require the reasoning channel to produce any output at all.
The determinism we need comes from temp=0 (greedy sampling). The
reasoning trace at think=true varies in prose but greedy sampling
converges to the same FINAL classification from identical starting
state, so signatures remain stable.
max_tokens restored to 3000 for the think trace + response.
9-run empirical test showed 20 of 27 audit_lessons signatures were
singletons (count=1) — the cloud producing slightly-different summary
phrasings for the SAME underlying claim on each audit, each hashing
to a fresh signature. That's the creep J flagged — not explosive,
but steady ~2 new sigs per run, unbounded over hundreds of runs.
Root cause: temperature=0.2 + think=true was letting variable prose
leak into the classification output. Fix: temp=0 (greedy sample →
identical input yields identical output on same model version),
think=false (no reasoning trace variance), max_tokens 3000→1500
(tighter bound prevents tail wander).
The compounding policy itself was validated by the 9 runs:
- 7 recurring claims (the legitimate signals) all at conf 0.08-0.20
- ratingSeverity() correctly held them at info (below 0.3 threshold)
- cross-PR signal test separately confirmed conf=1.00 → sev=block
Also: LH_AUDIT_RUNS env so the test can validate with smaller N.
lakehouse/auditor 1 blocking issue: cloud: claim not backed — "the proven escalation ladder with learning context, collects"
Phase 1 — definition-layer over append-only JSONL scratchpads.
auditor/kb_index.ts is the single shared aggregator:
aggregate<T>(jsonlPath, { keyFn, scopeFn, checkFn, tailLimit })
→ Map<signature, {count, distinct_scopes, confidence,
first_seen, last_seen, representative_summary, ...}>
ratingSeverity(agg) — confidence × count severity policy shared
across all KB readers. Kills the "same unfixed PR inflates its
own recurrence score" failure mode by design: confidence =
distinct_scopes/count, so same-scope noise stays below the 0.3
escalation threshold no matter how many times it repeats.
checkAuditLessons now routes through aggregate + ratingSeverity.
Net effect: the recurrence detector's bespoke Map/Set bookkeeping is
gone; same behavior, shared discipline, reusable by scrum/observer.
Also: symbolsExistInRepo now skips files >500KB so the audit can't
get stuck slurping a fixture.
Phase 2 — nine-consecutive audit runner.
tests/real-world/nine_consecutive_audits.ts pushes 9 empty commits,
waits for each verdict, captures the audit_lessons aggregate state
after each run, reports:
- sig_count trajectory (should stabilize, not grow linearly)
- max_count trajectory (same-signature repeat rate)
- max_confidence trajectory (must stay LOW on same-PR noise)
- verdict_stable across runs (must NOT oscillate)
This is the empirical proof that the KB compounds favorably:
noise doesn't escalate itself, and signal stays distinguishable.
Unit-tested both failure modes: same-PR × 9 repeats = conf=0.11
(info); cross-PR × 5 distinct = conf=1.00 (block). The rating
function correctly discriminates.
lakehouse/auditor 1 blocking issue: cloud: claim not backed — "the proven escalation ladder with learning context, collects"
Observed on PR #8 audit (de11ac4): 7 warn findings, all from the
cloud inference check. Investigation showed two distinct bug classes
that weren't "ship bad code", they were "auditor misreads the diff":
1. Cloud flagged "X not defined in this diff / missing implementation"
for symbols like `tailJsonl` and `stubFinding` that ARE defined —
just not in the added lines of this diff. Fix: extract candidate
symbols from the cloud's gap summary, grep the repo for their
definitions (function/const/let/def/class/struct/enum/trait/fn).
If every named symbol resolves, drop the finding; if some do,
demote to info with the resolution in evidence.
2. Cloud flagged runtime metrics like "58 cloud calls, 306s
end-to-end" as unbacked claims. These are empirical outputs
from running the test, not things a static diff can prove.
Fix: claim_parser now has an `empirical` strength class
matching iteration counts, cloud-call counts, duration metrics,
attempt counts, tier-count phrases. Inference drops empirical
claims from its cloud prompt (verifiable[] subset only) and
claim-index mapping uses verifiable[] so cloud responses still
line up.
Added `claims_empirical` to audit metrics so the verdict is
introspectable: how many claims WERE runtime-only vs how many
are diff-verifiable?
Verified: unit tests confirm empirical classification on 5
sample commit messages; symbol resolver found both false-positive
symbols (tailJsonl + stubFinding) and correctly skipped a known-
fake symbol.
Adds State section entries for the two KB files that close the
feedback loop: audit_lessons.jsonl (findings → recurrence detector)
and scrum_reviews.jsonl (scrum output → kb_query surfacing).
Touch-commit to trigger re-audit on fresh SHA with the restarted
auditor (which now has the fix-loaded code).
lakehouse/auditor 2 blocking issues: unimplemented!() macro call in tests/real-world/hard_task_escalation.ts
Two changes that fell out of running the auto-loop for real on PR #8:
1. The systemd auditor blocked PR #8 on 'unimplemented!()' / 'todo!()'
in tests/real-world/hard_task_escalation.ts — but those strings are
the rubric itself, not macro calls. Added isInsideQuotedString()
detection in static.ts: BLOCK_PATTERNS now skip matches that fall
inside double-quoted / single-quoted / backtick string literals on
the added line. WARN/INFO patterns still run — a TODO comment in
a string is still a valid signal.
2. Verdicts were being persisted to disk but never fed back as
learning signal. Added appendAuditLessons() — every block/warn
finding writes a JSONL row to data/_kb/audit_lessons.jsonl with a
path-agnostic signature (strips file paths, line numbers, commit
hashes) so the SAME class of finding on DIFFERENT files dedups to
one signature.
kb_query now tails audit_lessons.jsonl and emits recurrence
findings: 2 distinct PRs hit a signature = info, 3-4 = warn, 5+ =
block. Severity ramps on distinct-PR count, not total rows, so a
single unfixed PR being re-audited doesn't inflate its own
recurrence score.
Fires on post-verdict fire-and-forget (can't break the audit if
disk write fails). The learning loop is now closed: each audit
contributes to the KB that guides the next audit.
Tested: unit tests for normalizedSignature confirmed path-agnostic
dedup; static.ts regression tests confirmed rubric strings no longer
trip BLOCK while real unquoted unimplemented!() still does.
lakehouse/auditor 2 blocking issues: unimplemented!() macro call in tests/real-world/hard_task_escalation.ts
Wires the cohesion-plan Phase C link: the scrum-master pipeline writes
per-file reviews to data/_kb/scrum_reviews.jsonl on accept; the
auditor now reads that same file and emits one kb_query finding per
scrum review whose `file` matches a path in the PR's diff.
Severity heuristic: attempt 1-3 → info, attempt 4+ → warn. Reaching
the cloud specialist (attempt 4+) means the ladder had to escalate,
which is meaningful signal reviewers should see. Tree-split fired is
also surfaced in the finding summary.
audit.ts now passes pr.files.map(f => f.path) into runKbCheck (the
old signature dropped it on the floor). Also adds auditor/audit_one.ts
— a dry-run CLI for auditing a single PR without posting to Gitea,
useful for verifying check behavior without spamming review comments.
Verified: after writing scrum_reviews for auditor/audit.ts and
mcp-server/observer.ts (both in PR #7), audit_one 7 surfaced both as
info findings with preview + accepted_model + tree_split flag. A
scrum review for playbook_memory.rs (NOT in PR #7) was correctly
filtered out.
Extends the scrum-master pipeline to handle input overflow on large
source files (>6KB). Previously, the review prompt truncated the file
to first-chunk, which caused false-positive "field is missing"
findings whenever the actual field was past the cutoff.
Now each file >FILE_TREE_SPLIT_THRESHOLD (6000) is sharded at
FILE_SHARD_SIZE (3500), each shard summarized via gpt-oss:120b cloud,
and the distillations merged into a scratchpad. The review then runs
against the scratchpad with an explicit truncation-awareness clause
in the prompt: "DO NOT claim any field, function, or feature is
'missing' based on its absence from this distillation."
Also writes each accepted review as a JSONL row to
data/_kb/scrum_reviews.jsonl (file, reviewed_at, accepted_model,
accepted_on_attempt, attempts_made, tree_split_fired, preview).
This is the source the auditor's kb_query reads to surface
per-file scrum reviews on PRs that touch those files (cohesion
plan Phase C).
Verified: scrum review of 92KB playbook_memory.rs → 27 shards via
cloud → distilled scratchpad → qwen3.5 local 7B accepted on attempt 1
(5931 chars). Tree-split fires, jsonl row appended, output file
contains structured suggestions.
The orchestrator J described: pulls git repo source + PRD +
suggested-changes doc, chunks them, hands each code piece through
the proven escalation ladder with learning context, collects
per-file suggestions in a consolidated handoff report.
Composes ONLY already-shipped primitives — no new core code:
- chunker with 800-char / 120-overlap windows
- sidecar /embed for real nomic-embed-text embeddings
- in-memory cosine retrieval for top-5 PRD + top-5 proposal
chunks per target file
- escalation ladder (qwen3.5 → qwen3 → gpt-oss:20b → gpt-oss:120b
→ devstral-2:123b → mistral-large-3:675b)
- per-attempt learning-context injection (prior failures as
"do not repeat" block)
- acceptance rubric (length ≥ 200 chars + structured form)
Live-run (tests/real-world/runs/scrum_moatqkee/):
targets: 3 files
- crates/vectord/src/playbook_memory.rs (920 lines)
- crates/vectord/src/doc_drift.rs (163 lines)
- auditor/audit.ts (170 lines)
resolved: 3/3 on attempt 1 by qwen3.5:latest local 7B
total duration: 111.7s
output: scrum_report.md + per-file JSON
Sample from scrum_report.md (playbook_memory.rs review):
- Alignment score: 9/10 vs PRD Phase 19
- 4 concrete change suggestions naming specific lines + PLAN/PRD
chunk offsets
- 3 gap analyses with PRD-reference citations
Honest findings from this run:
1. Local 7B handled review-style tasks first-try. The escalation
ladder infrastructure is live but didn't fire — review is an
easier task shape than strict code-generation (see hard_task
test which needed devstral-2 specialist).
2. 6KB file-truncation caused one false positive: model claimed
playbook_memory.rs lacks a `doc_refs` field, but that field
exists past the 6KB cutoff. Trade-off between context-size
and review-depth needs tuning per file.
3. Chunk-offset citations are real: model output includes
`[PRD @27880]` and `[PLAN @16320]` which map to the actual
byte offsets of retrieved context chunks. Auditor pattern could
adopt this for traceable claims.
This is the scrum-master-handoff shape J asked for:
repo + PRD + proposal → chunk → retrieve → escalate → consolidate
→ human-reviewable markdown report
Not shipping: per-PR diff analysis, open-PR integration, Gitea
posting of suggestions. Those compose the same primitives
differently — this proves the core pattern.
Env override: LH_SCRUM_FILES=path1,path2,... to target a different
file set. Default 3 files keeps runtime ~2min.

J asked (2026-04-22): construct a task the local model provably can't
complete, then watch the escalation + retry + cloud pipeline actually
solve it.
The task: generate a Rust async function with 15 specific
structural rules (exact signature, bounded concurrency, exponential
backoff 250/500/1000ms, NO .unwrap(), rustdoc comments, etc.).
Small enough to fit in one response but strict enough that one
rule violation = not accepted. Fits Rust + async + concurrency +
error-handling — across the hardest dimensions for 7B models.
Escalation ladder (corrected per J — kimi-k2.x requires Ollama
Cloud Pro subscription which J's key lacks; mistral-large-3:675b
is the biggest provisioned model):
1. qwen3.5:latest (local 7B)
2. qwen3:latest (local 7B)
3. gpt-oss:20b (local 20B)
4. gpt-oss:120b (cloud 120B)
5. devstral-2:123b (cloud 123B coding specialist)
6. mistral-large-3:675b (cloud 675B — biggest available)
Each attempt gets PRIOR failures' rubric violations injected as
learning context. Loop caps at MAX_ATTEMPTS=6.
Live run (runs/hard_task_moapd3g3/):
attempt 1: qwen3.5:latest 11/15 — missed concurrency + some constraints
attempt 2: qwen3:latest 11/15 — different misses after learning
attempt 3: gpt-oss:20b 0/1 — empty response (local model dead-end)
attempt 4: gpt-oss:120b 0/1 — empty (heavy learning context may confuse)
attempt 5: devstral-2:123b 15/15 ✅ ACCEPTED after 10.4s
attempt 6: (not reached)
Total: 5 attempts, 145.6s, coding-specialist succeeded.
Honest findings from the run:
- Pipeline works: escalated through 4 distinct model tiers, injected
learning, bounded at 6, graceful failure surfaces.
- Learning injection doesn't always help general-purpose models —
gpt-oss:120b returned empty when given heavy prior-failure context
(attempt 4). The coding specialist (devstral) worked better because
the task is domain-aligned.
- Local 7B came within 4 rules of success first-try (11/15) — not
bad for the scale, but specific constraints like "EXACT signature"
and "bounded concurrency at 4" are where small models slip.
- Kimi K2.5/K2.6 both require a paid subscription on our current
Ollama Cloud key — verified via direct ollama.com curl. Swap
to kimi once subscription lands.
Also includes a rubric bug-fix caught in the run: the regex for
"reaches 500/1000ms backoff" originally required literal constants,
but devstral-2:123b wrote idiomatic `retry_delay *= 2;` which
doubles 250 → 500 → 1000 correctly. Broadened rubric to recognize
`*= 2`, bit-shift, `.pow()`, and literal forms. Without this the
ladder would have false-failed on semantically-correct code.
Files:
tests/real-world/hard_task_escalation.ts (270 LOC)
tests/real-world/runs/hard_task_moapd3g3/
attempt_{1..5}.txt — raw model outputs (last successful)
attempt_{1..5}.json — per-attempt rubric verdict + error
summary.json — ladder summary
What this PROVES that no prior test did:
- Task-level retry ESCALATES across distinct model capabilities
(not just same model retried)
- Bigger and more-specialized models ACTUALLY solve what smaller
ones can't — the ladder works by design, not by luck
- The subscription boundary (Kimi K2.x) is a real operational
constraint, not a code issue
- Rubric engineering is its own discipline — a strict-but-wrong
validator can reject correct code; shipping the test harness
required tuning against actual model outputs

Two distinct retry loops now both cap at 6 and serve different
purposes:
1. Per-cloud-call continuation (Phase 21 primitive) — when a single
cloud call returns empty or truncated, stitches up to 6
continuation calls. Handles output-overflow.
2. Per-TASK retry (this commit) — when the whole task errors
(500/404, thin answer, etc.), retries the full task up to 6
times. Each retry gets PRIOR ATTEMPTS' failures injected into
the prompt as learning context, so attempt N+1 is informed by
what N failed at. Handles error-recovery with compounding
context.
Both loops fired on iter 3 of the stress run, proving them
independent and composable:
FORCING TASK-RETRY LOOP — iter 3 will cycle through 5 invalid
models + 1 valid
attempt 1/6: model=deliberately-invalid-model-attempt-1
/v1/chat 502: ollama.com 404: model not found
attempt 2/6: [with prior-failure context]
... (5 failures total, each with the full chain of prior errors)
attempt 6/6: model=gpt-oss:20b [with prior-failure context]
continuation retry 1..6 (empty responses)
SUCCEEDED after 5 prior failures (441 chars)
What J was asking to prove:
"I expect it to retry the process six times to build on the
knowledge database... when an error is legitimately triggered
that it will go through six times... without getting caught in
a loop"
Proof:
- 6/6 attempts fired on the FORCED iteration
- Each retry embedded the preceding attempts' errors as "do not
repeat" context
- Hard cap at MAX_TASK_RETRIES (6) prevents infinite loops
- Last-ditch local fallback exists if all 6 still fail
- Other iterations succeed on attempt 1 — the loop ONLY fires
when errors are legitimately triggered
Stress run totals (runs/moan4h71/):
6/6 iterations complete, 58 cloud calls, 306s end-to-end
tree-splits: 6/6 continuations: 10 rescues: 2
iter 3: 8197+2800 tok, 6 task attempts, 6 continuation retries
local stored summary + per-iter JSON for inspection
What this proves that prior stress runs did NOT:
- Error-recovery at task granularity is live, not aspirational
- Compounding failure context flows between retries as text
- Loop bound is enforced; runaway cases aren't possible
- Two retry mechanisms compose without deadlock (continuation
inside task-retry inside tree-split)
Follow-ups worth doing (separate PRs):
- Persist retry-history to observer :3800 so cross-run learning
sees the failure patterns
- Route retries through /vectors/hybrid to surface similar prior
errors from the real KB (currently only in-memory across one
iteration)
- Fix citation regex in summary — iter 6 received 5 prior IDs
but counter shows 0 (regex needs to tolerate hyphens in IDs)
Real end-to-end test of the Lakehouse pipeline at scale. Runs the
PRD (63 KB, 901 lines → 93 chunks) through 6 iterations with cloud
inference, intentional failure injection, and tight context budget
to force every Phase 21 primitive to fire.
What the test exercises:
- Sidecar /embed for 93 chunks (nomic-embed-text)
- In-memory cosine retrieval for top-K per iteration
- Tree-split (shard → summarize → scratchpad → merge) when context
chunks exceed the 4000-char budget
- Scratchpad truncation to keep compounding context bounded
- Cloud inference via /v1/chat provider=ollama_cloud (gpt-oss:120b)
- Injected primary-cloud failure on iter 3 (invalid model name) +
rescue with gpt-oss:20b — proves catch-and-retry isn't dead code
- Playbook seeding per iteration (real HTTP against gateway)
- Prior-iteration answer injection for compounding (not just IDs —
the first version passed IDs only and the model ignored them)
Live run results (tests/real-world/runs/moamj810/):
6/6 iterations complete, 42 cloud calls total, 245s end-to-end
tree-splits: 6/6 (every iter overflowed 4K budget)
continuations: 0 (no responses hit max_tokens)
rescues: 1 (iter 3 injected failure → gpt-oss:20b → valid answer)
iter 6 answer explicitly cites [pb:pb-seed-82e1] — compounding real
scratchpad truncation fired on iter 6 as designed
What this PROVES:
- Tree-split primitives work under real context pressure, not just
in unit tests. The 4000-char budget forced every iteration to
shard 12 chunks → 6 shards → scratchpad → final answer.
- Rescue on primary failure is wired and produces answers from a
weaker model rather than erroring out.
- Compounding context injection works: iter 6's prompt had the 5
prior answers in its citation block, and the cloud model
acknowledged at least one via [pb:...] notation.
- The existence claims in Phase 21 (continuation + tree-split) are
backed by executable evidence, not just unit tests.
What this DOESN'T prove (deliberate — scoped for follow-up):
- Continuation retries (no iter hit max_tokens in this run; would
need a harder prompt or lower max_tokens to force)
- Real integration with /vectors/hybrid endpoint (test does in-memory
cosine instead, bypassing gateway vector surface)
- Observer consumption of these runs (nothing posted to :3800 during
the test — adding that is Phase A integration, handled separately)
Files:
tests/real-world/enrich_prd_pipeline.ts (333 LOC)
tests/real-world/runs/moamj810/{iter_1..6.json, summary.json}
— artifacts from the stress run, committed for inspection
Follow-ups worth doing:
1. Lower max_tokens / harder prompt to force continuation path
2. Route retrieval through /vectors/hybrid for real Phase 19 boost
3. POST per-iteration summary to observer :3800 so runs accumulate
like scenario runs do

lakehouse/auditor cloud: claim not backed — "Previously the hybrid fixture honestly reported layer 5 as 404/unimplemented. With this PR it flips "
Closes the last open loop of Phase 45. Previously, playbooks could
carry doc_refs (slice 1) and the context7 bridge could report drift
(slice 2) — but nothing tied them together. An operator had no way
to say "check this playbook against its doc sources and flag it if
the docs moved." This slice wires that.
Ships:
- crates/vectord/src/doc_drift.rs — thin context7 bridge client.
No cache (bridge has its own 5-min TTL). No retry (transient
failure = Unknown outcome, caller decides).
- PlaybookMemory::flag_doc_drift(id) — stamps doc_drift_flagged_at
idempotently. Once flagged, compute_boost_for_filtered_with_role
excludes the entry from both the non-geo and geo-indexed boost
paths until resolved.
- PlaybookMemory::resolve_doc_drift(id) — human re-admission.
Stamps doc_drift_reviewed_at which clears the boost exclusion.
- PlaybookMemory::get_entry(id) — new read-only accessor the
handler uses to read doc_refs without exposing the state lock.
- POST /vectors/playbook_memory/doc_drift/check/{id}
- POST /vectors/playbook_memory/doc_drift/resolve/{id}
Design call: Unknown outcomes from the bridge (bridge down, tool
not in context7, no snippet_hash recorded) are NEVER enough to
flag. Only a positive drifted=true from the bridge flips the flag.
A down bridge doesn't silently drift-flag every playbook.
Tests (5 new, in upsert_tests mod):
- flag_doc_drift_stamps_timestamp_and_persists
- flag_doc_drift_is_idempotent_on_already_flagged
- resolve_doc_drift_clears_flag_admission_gate
- boost_excludes_flagged_unreviewed_entries
- boost_re_admits_resolved_entries
14/14 upsert tests pass (9 pre-existing + 5 new).
Live end-to-end — hybrid fixture on auditor/scaffold (merged to
main at b6d69b2) now shows:
overall: PASS
shipped: [38, 40, 45.1, 45.2, 45.3]

Promotes two previously manual-start Bun services to systemd
so they survive restarts + run continuously.
- ops/systemd/lakehouse-auditor.service — polls Gitea every 90s,
runs 4 audit checks per PR head SHA, posts commit status + review
comment. Runs as root to match existing lakehouse-* service
conventions on this host; can read /home/profit/.git-credentials
(0600 profit:profit).
- ops/systemd/lakehouse-context7-bridge.service — HTTP wrapper on
:3900 for Phase 45 doc-drift detection. Decoupled from gateway;
runs independently.
- ops/systemd/install.sh — idempotent installer (copy → daemon-reload
→ enable --now). Prints post-install active/enabled status.
- ops/systemd/README.md — run/stop/logs/pause docs.
Pause control stays per-service (bot.paused / auditor.paused files
at repo root). Not wired to branch protection yet — the auditor's
commit status is currently advisory, not enforcing. Flip via Gitea
branch_protections API when confident.
After merging main (with the UpsertOutcome struct-like enum shape
from PR #2), the 4 new upsert tests needed pattern-match updates:
UpsertOutcome::Added(_) → UpsertOutcome::Added { .. }
9/9 upsert tests pass.
Auditor found this via hybrid fixture 2026-04-22. Blocks the serde-tag-newtype shape by converting to struct-like variants. See PR #2 body for full context.
Manual merge: auditor commit status was failure due to 1 false-positive inference finding on a commit-message reference; underlying fix is verified (curl against live gateway confirmed all 3 upsert paths return valid JSON). Proceeding per human review.
lakehouse/auditor all checks passed (3 findings, all info)
The auditor's hybrid fixture (branch auditor/scaffold) surfaced this
on 2026-04-22. A re-seed of the same (operation, day) pair with new
endorsed_names merged the names but silently discarded the incoming
doc_refs and valid_until fields. schema_fingerprint was partially
handled (set-if-Some) but doc_refs and valid_until weren't touched.
Root cause: the UPDATE arm of upsert_entry at playbook_memory.rs:609
only covered:
- endorsed_names (union-merge)
- timestamp
- embedding (if Some)
- schema_fingerprint (if Some)
Fix:
- valid_until — refresh if caller provides one
- doc_refs — merge by tool (case-insensitive). Same-tool new entry
supersedes older one; different-tool refs are appended. Empty
incoming doc_refs preserves existing (don't wipe on partial seed).
4 new regression tests under upsert_tests:

Test result: 9/9 upsert tests pass (4 new + 5 pre-existing).
Branch basis note: this branch is off main, so the UpsertOutcome enum
here still has the newtype variants Added(String) / Noop(String). PR
#2 (fix/upsert-outcome-serde) changes that enum to struct-like. When
PR #2 merges first this branch needs a trivial rebase; the UPDATE
arm logic is untouched by that change.

lakehouse/auditor all checks passed (4 findings, all info)
auditor/index.ts (task #9) — the top-level poller. 90s interval,
dedupes by head SHA via data/_auditor/state.json, supports --once
for CLI testing. Env gates: LH_AUDITOR_RUN_DYNAMIC=1 to include
the hybrid fixture (default off; it mutates live state),
LH_AUDITOR_SKIP_INFERENCE=1 for fast runs without cloud calls.
Single-shot run proof (task #10):
cycle 1: 2 open PRs
audit PR #2 f0a3ed68 "Fix: UpsertOutcome newtype serde panic"
verdict=block, 9 findings (1 block, 5 warn, 3 info)
audit PR #1 039ed324 "Auditor: PR-claim hard-block reviewer"
verdict=approve, 4 findings (0 block, 0 warn, 4 info)
audits_run=2, state persisted
Commit statuses and issue comments posted live to Gitea. PR #2 is
currently hard-blocked (lakehouse/auditor commit status = failure);
PR #1 has a passing status. State survives restart — next cycle
skips already-audited SHAs.
Both PRs now have the audit comment with per-check breakdown.
Operator can read the comment, fix blocking findings (or defend
them with a reply), push a new commit; auditor re-audits on new
SHA, verdict updates, merge gate responds accordingly.
The full loop J asked for is closed:
1. static check caught own Phase 45 placeholder (b933334)
2. hybrid fixture caught UpsertOutcome serde panic (9c893fb)
3. LLM-Team-style codereview caught ternary bug (5bbcaf4)
4. auditor poller now runs on every open PR, block/approve with
evidence, re-audits on new SHAs
Tasks done: 1-11 (except 12, a scoped follow-up fix for UPDATE
branch dropping doc_refs). The auditor is running, catching real
bugs in its own build, and gating merges.
After the serde fix (PR #2, fix/upsert-outcome-serde) landed on main,
re-running this fixture STILL reported "doc_refs field is empty" —
but with a different root cause than the panic.
Root cause: pre-fix runs panicked on response serialization but had
already added entries to state (panic happened between upsert_entry
returning and the handler's serde_json::json! of the response). So
state.json was polluted with __auditor_test_worker__ entries from
those runs, WITHOUT doc_refs (doc_refs wasn't even wired at the time
those state rows were written).
The fixture's `find(endorsed_names.includes(TEST_WORKER_NAME))` was
picking the oldest polluted entry, not the fresh one.
Compounding: discovered a secondary bug while investigating —
upsert_entry's UPDATE branch only merges endorsed_names. doc_refs,
schema_fingerprint, valid_until on an UPDATE are silently dropped.
Filed as task #12, separate PR to follow.
Fix in this fixture: use a nonce suffix on both TEST_WORKER_NAME and
TEST_OPERATION so every run is guaranteed to hit the ADD path in
upsert_entry, sidestepping the UPDATE bug AND eliminating state
pollution entirely.
Live re-run after this edit:
✓ Phase 38 /v1/chat 449ms, 42 tokens
✓ Phase 40 Langfuse trace 20ms
✓ Phase 45.1 seed + doc_refs 239ms, doc_refs.length=1 persisted
✓ Phase 45.2 bridge diff 2ms, drifted=true
✗ Phase 45.3 drift-check HONEST 404 (endpoint not built)
shipped_phases: [38, 40, 45.1, 45.2] (was [38, 40, 45.2])
placeholder: [45.3] (was [45.1, 45.3])
One fewer placeholder — exactly because the serde fix merged on
fix/upsert-outcome-serde and the fixture now cleanly exercises the
path. The loop is:
fixture finds bug → PR fixes bug → fixture re-run confirms fix →
one fewer placeholder.
lakehouse/auditor 1 blocking issue: cloud: claim not backed — "Verified live after gateway restart:"
playbook_memory.rs:257 — UpsertOutcome had two newtype variants
carrying a bare String:
Added(String)
Noop(String)
under #[serde(tag = "mode")]. serde cannot tag newtype variants of
primitive types, so every serialization threw:
"cannot serialize tagged newtype variant UpsertOutcome::Added
containing a string"
This caused gateway /vectors/playbook_memory/seed to panic the
tokio worker on EVERY call that reached Added or Noop, returning
an empty socket close to the client. The bug was silent from commit
640db8c (Phase 26, 2026-04-21) until 2026-04-22 when the auditor's
hybrid fixture (auditor/fixtures/hybrid_38_40_45.ts on the
auditor/scaffold branch) exercised the endpoint live and gateway
logs showed the panic.
Fix — convert both newtype variants to struct-like:
Added { playbook_id: String }
Noop { playbook_id: String }
Updated all 7 construction + pattern-match sites. Updated rustdoc
on the enum explaining why the shape is what it is.
JSON wire format is now uniform across all three variants:
{"mode":"added","playbook_id":"pb-..."}
{"mode":"updated","playbook_id":"pb-...","merged_names":[...]}
{"mode":"noop","playbook_id":"pb-..."}
Verified live after gateway restart:
curl /seed new payload → mode=added, playbook 860231f5
curl /seed new payload + doc_refs → mode=added, playbook 11d348d9
curl /seed identical re-submit → mode=noop, same id 860231f5,
entries_after unchanged (Mem0
contract intact)
Tests: 51/51 vectord lib tests green. Release build clean.
This is a follow-up bug fix landed in its own branch
(fix/upsert-outcome-serde) rather than commingled with other work.
The auditor's hybrid fixture on the auditor/scaffold branch will
now light up layer 3 (phase45_seed_with_doc_refs) as a pass once
this merges — previously it failed here with an empty socket close.
Caught by running a side-test through LLM Team's run_codereview
flow (gpt-oss:120b reviewer) against this fixture, 2026-04-22.
BEFORE:
const ourStart = Date.parse(
l1.evidence.match(/tokens=/) ? result.ran_at : result.ran_at
);
// Both branches return result.ran_at — the ternary is meaningless.
// result.ran_at is the fixture start time, NOT the moment we fired
// /v1/chat. Any trace created between fixture-start and chat-fetch
// would false-negative.
AFTER:
const chat_request_sent_ms = Date.now(); // captured before layer 1
// ...
const recent = items.filter(t =>
Date.parse(t.timestamp) >= chat_request_sent_ms
);
Re-ran the fixture against the live stack — layers 1,2,4 still pass
(no regression); layer 2 trace matched at age=2494ms which is within
the chat-to-trace propagation window. Layers 3,5 still fail for the
original unrelated reasons (UpsertOutcome serde panic + Phase 45
slice 3 endpoint not built).
First concrete act-on-finding from a code-checker run. The process
works.
auditor/fixtures/hybrid_38_40_45.ts — the never-before-run hybrid
test. Exercises Phase 38 /v1/chat → Phase 40 Langfuse → Phase 45
slice 1 seed+doc_refs → Phase 45 slice 2 bridge drift → (expected-
fail) Phase 45 slice 3 drift-check endpoint.
auditor/fixtures/cli.ts — standalone runner. Human-readable summary
to stderr, machine-readable JSON to stdout, exit code 0/1/2 for
pass / fail / partial_pass.
Live run results — honest measurements, not hand-waved:
✓ Phase 38 /v1/chat returns 9 visible tokens, 6.7s latency
("docker run is a common Docker command.")
✓ Phase 40 Langfuse trace 18a8a0b7 landed in 2.5s
✗ Phase 45.1 seed endpoint returns empty reply — discovered a
PRE-EXISTING BUG unrelated to doc_refs:
playbook_memory.rs:257 UpsertOutcome has newtype
variants Added(String) and Noop(String) under
#[serde(tag="mode")] — serde panics on serialize.
panicked at crates/vectord/src/service.rs:2323:
Error("cannot serialize tagged newtype variant
UpsertOutcome::Added containing a string")
Reproduced: curl /seed with AND without doc_refs
both get "Empty reply from server" (socket closed
mid-response). This bug has existed since Phase 26
shipped (commit 640db8c, 2026-04-21). No test or
caller in the repo exercised the response path live
against the gateway until this fixture did.
✓ Phase 45.2 context7 bridge confirms drift: current hash
475a0396ca436bba vs our stale input, upstream last
updated 2026-04-20
✗ Phase 45.3 /doc_drift/check endpoint — correctly unreachable
because layer 3 blocked us from getting a playbook_id;
endpoint still doesn't exist independent of that
Real numbers published: per-layer latency_ms, token counts,
trace_age_ms, library_id, current_hash_length. All stored in the
JSON output for downstream audit.
Value delivered: the fixture's first live run found a bug that
unit tests, compile checks, and my own "phase shipped" commits all
missed. Exactly the gap J called out — the auditor is doing what
it's supposed to do.
Bug fix is a SEPARATE concern: new task #11 tracks a separate PR
(fix/upsert-outcome-serde) so the audit finding and the fix stay
cleanly attributed.
auditor/checks/static.ts — grep-style scan of PR diffs, no AST,
no LLM. High-signal patterns only.
Severity grading:
- BLOCK — unimplemented!(), todo!(), panic!("not implemented"),
throw new Error("not implemented")
- WARN — TODO/FIXME/XXX/HACK in added lines;
new pub struct fields with <2 mentions in the diff
(added but nobody reads it — placeholder state)
- INFO — hardcoded "placeholder"/"dummy"/"foobar"/"changeme"/"xxx"
strings in added lines
Live-proven — the existential test J asked for:
vs PR #1 (scaffold): 0 findings (all scaffold fields cross-
reference within the diff)
vs commit 2a4b81b (Phase 5 WARN: every DocRef field (tool,
45 first slice — I version_seen, snippet_hash, source_url,
half-admitted placeholder): seen_at) added with 0 read-sites in
the diff
That's the auditor flagging my own "Phase 45 first slice" commit as
state-without-consumer, which is exactly what I half-admitted it
was. If PR #1 had required auditor-pass (branch protection), the
DocRef commit would have been blocked pre-merge. The auditor works
because it agreed with the honest read.
Next: dynamic hybrid test fixture (task #4) — the never-run multi-
layer pipeline test.
auditor/claim_parser.ts — reads PR body + commit messages, extracts
ship-claims. Regex-based, intentionally not LLM-driven: the parser's
job is to surface claim substrates, not to judge them (that's the
inference check's job, runs later with cloud model).
Three strength tiers:
- strong — "verified end-to-end", "live-proven", "production-ready",
"phase N shipped", "proven"
- moderate — "shipped", "landed", "green", "passing", "works",
"complete", "done"
- weak — "should work", "expected to", "probably"
Live-proven against PR #1 (this PR): 4 claims extracted from
1 commit (2 strong, 2 moderate). "live-proven" correctly tagged as
strong (it IS a stronger claim than "shipped").
Next: static diff check consumes these claims + the PR diff to find
placeholder patterns — empty fns, TODO, unwired fields, etc.
All-Bun sub-agent that watches open PRs on Gitea, reads ship-claims,
and hard-blocks merges when the code doesn't back the claim. First
commit of N; this is the skeleton. Dynamic/static/inference/kb checks
+ poller land in follow-up commits on this same branch.
- auditor/types.ts — Claim, Finding, Verdict, PrSnapshot shapes
- auditor/gitea.ts — minimal API client (listOpenPrs, getPrDiff,
postCommitStatus, postReview). Live-proven: returned 0 open PRs
against our repo (which IS the current state — every commit today
went to main directly, which is the problem this auditor is meant
to prevent)
- auditor/policy.ts — stub `assembleVerdict` + severity rules.
Intentionally conservative defaults: strong claim + zero evidence
= block, not warn.
- auditor/README.md — how to run + the hard-block mechanism
Workflow discipline change: starting with this branch, no more
direct pushes to main. Every change lands as a PR. When this
auditor is fully built and running, it'll review its own
completion PR — the recursive self-test.

Bun bridge on :3900 that wraps context7's public API and exposes the
surface gateway consumes for Phase 45 drift checks. Own port so a
failure here never tips over mcp-server on :3700.
Endpoints:
GET /health status + cache stats
GET /docs/:tool resolve tool → library_id → fetch
docs → return descriptor
{snippet_hash, last_updated,
source_url, docs_preview, ...}
GET /docs/:tool/diff?since=X compare current snippet_hash to X;
returns {drifted: bool, current,
previous, preview if drifted}
GET /cache debug dump of cached entries
Implementation notes:
- 5 minute in-memory cache (context7 rate-limits by IP; gateway
drift-checks are the hot caller)
- 1500-token slices from context7 (enough for drift-meaningful
hash, not so much we hammer their API)
- snippet_hash = SHA-256 prefix (16 hex chars) of fetched content
- Library resolution prefers "finalized" state; falls back to top
result if none finalized
Verified live against context7.com:
- /health → ok, 0 cache, 300s TTL
- /docs/docker → library_id /docker/docs,
title "Docker", hash
475a0396ca436bba, last
updated 2026-04-20
- /docs/docker (again) → cache hit, 0.37ms
(5400× speedup)
- /docs/docker/diff?since=stale-hash-0000 → drifted=true, preview
included
- /docs/docker/diff?since=<current hash> → drifted=false, preview
omitted (honest: no
drift to show)
Not yet wired:
- Gateway consumer (Phase 45 slice 3):
/vectors/playbook_memory/doc_drift/check/{id} calls this bridge
and updates DocRef.snippet_hash + doc_drift_flagged_at
- Systemd unit (bridge is manual-start for now, same as bot/)

Phase J keeps asking for: playbooks know which external docs they
used, get flagged when those docs drift. This commit ships the data
model; context7 bridge + drift check endpoints land in follow-ups.
Added to crates/vectord/src/playbook_memory.rs:
- pub struct DocRef { tool, version_seen, snippet_hash, source_url,
seen_at } — one external doc reference
- PlaybookEntry.doc_refs: Vec<DocRef> — empty on legacy entries,
serde default ensures pre-Phase-45 persisted state loads cleanly
- PlaybookEntry.doc_drift_flagged_at: Option<String> — set by the
(future) drift-check code when context7 reports newer version
- PlaybookEntry.doc_drift_reviewed_at: Option<String> — set by
human via /resolve endpoint after reviewing the diagnosis
- impl Default for PlaybookEntry — collapses most test-helper
constructors from 17 explicit fields to 6-9 fields +
..Default::default()
Updated SeedPlaybookRequest + RevisePlaybookRequest (service.rs) to
accept optional doc_refs: the seed/revise endpoints already take the
field, downstream drift detection (Phase 45.2) consumes it.
Docs: docs/CONTROL_PLANE_PRD.md gains full Phase 45 spec with gate
criteria, non-goals, and risk notes.
Tests: 51/51 vectord lib tests green (same count as before, field
additions are backward-compat).
Memory: project_doc_drift_vision.md written so this keeps coming
back to the front of mind.
Next slices (same phase): context7 HTTP bridge in mcp-server,
/vectors/playbook_memory/doc_drift/check/{id} endpoint, overview-
model drift synthesis writing to data/_kb/doc_drift_corrections.jsonl,
boost exclusion for flagged+unreviewed entries.
