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.

Lakehouse Claim Auditor

A Bun sub-agent that watches open PRs on Gitea, reads the ship-claims in commit messages and PR bodies, and hard-blocks merges when the code doesn't back the claim.

Rationale: when "compiles + one curl works" gets called "phase shipped," placeholder code accumulates. This auditor runs every 90s, fetches each open PR, and subjects it to four checks:

  1. Static diff — grep/parse looking for placeholder patterns
  2. Dynamic — runs the never-before-executed hybrid test fixture
  3. Cloud inference — asks gpt-oss:120b via /v1/chat to identify gaps in the diff
  4. KB query — looks up data/_kb/ + observer for prior failure patterns on similar claims

Verdict is assembled, posted to Gitea as:

  • A failing commit status (hard block — branch protection prevents merge)
  • A review comment explaining every finding

Run manually

cd /home/profit/lakehouse
bun run auditor/index.ts

Defaults: polls every 90s, stops on auditor.paused file present.

State

  • data/_auditor/state.json — last-audited head SHA per PR
  • data/_auditor/verdicts/{pr}-{sha}.json — per-run verdict record
  • data/_kb/audit_lessons.jsonl — one row per block/warn finding, path-agnostic signature for dedup. Tailed by kb_query on each audit to surface recurring patterns (2+ distinct PRs with same signature → info, 3-4 → warn, 5+ → block). This is how the auditor learns.
  • data/_kb/scrum_reviews.jsonl — scrum-master per-file reviews. If a file in the current PR has been scrum-reviewed, kb_query surfaces the review as a finding with the accepted model and attempt count.

Where YOU edit

auditor/policy.ts — the verdict assembler. Controls which findings block vs warn vs inform. All other code is mechanical: fetching, running checks, posting to Gitea.

Hard-block mechanism

  1. Commit status is posted as failure with context lakehouse/auditor
  2. If main branch protection requires lakehouse/auditor status to pass, Gitea prevents merge
  3. When code is fixed and re-audit passes, status flips to success, merge unblocks

Enable branch protection (one-time, via Gitea UI or API):

  • POST /repos/profit/lakehouse/branch_protections
  • {"branch_name": "main", "required_status_checks": {"contexts": ["lakehouse/auditor"]}}
