fact_extractor: project context + fixed verifier-verdict parser
Two bundled changes. Both came out of J's observation that the
verifier was defaulting to UNVERIFIABLE on domain-specific facts
because it had no idea what Lakehouse was, which project's code it
was reading, or what framework the types belonged to.

1. Project context preamble. Added docs/AUDITOR_CONTEXT.md — a <400-
   word concise description of the project (crates, services,
   architecture phases, the auditor's role itself). fact_extractor
   reads it once, caches it, prepends it to the extract prompt as a
   "PROJECT CONTEXT (for grounding; do NOT extract from this)"
   section. Both extractor and verifier now see this context, so
   statements like "aggregate<T> returns Map<string, AggregateRow>"
   get grounded as "this is a TypeScript function in the Lakehouse
   auditor subsystem" and the verifier can reason about plausibility
   instead of guessing.

2. Verifier-verdict parser fix. Gemma2's output format varies between
   "**Verdict:** CORRECT" and just "* **CORRECT**" inline (observed
   variance across runs). The old regex required "Verdict:" as a
   label and missed the second format — causing all verdicts to
   stay UNCHECKED. Replaced with a two-pass approach: find each
   fact section start ("**N.**" or "N."), slice to the next section,
   scan the slice for the first CORRECT|INCORRECT|UNVERIFIABLE
   token. Handles both formats plus unfenced fallback.

Verified: 4-fact test extraction went from 0/4 verdicts scored
(pre-fix) to 2/4 CORRECT + 2/4 UNVERIFIABLE (post-fix). The 2
UNVERIFIABLE cases are domain-specific code behavior the verifier
legitimately can't confirm without reading source — correct stance,
not a parser miss.

No new consensus modes yet. J suggested adding codereview or
validator as a second pass; holding until we see whether context
injection alone gives sufficient signal lift.

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"]}}
