profit c5da680add Fixture: unique-per-run nonce eliminates state-pollution false positive
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.

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 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

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"]}}
