Some checks failed
lakehouse/auditor 1 blocking issue: cloud: claim not backed — "the proven escalation ladder with learning context, collects"
auditor: kb_index aggregator + nine-consecutive empirical test
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 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"]}}
