root 107a68224d auditor: skip serde-derived structs in unread-field check
Fields on structs that derive Serialize or Deserialize ARE read — by
the macro, on every JSON round-trip — but the static check only
looked for explicit `.field` references in the diff. Result: every
new response/request struct shipped through `/v1/*` was flagged as
"placeholder state without a consumer."

PR #11 head 0844206 surfaced 8 such false positives across mode.rs,
respond.rs, truth.rs, and profiles/memory.rs — same shape as the
existing string-literal exemption for BLOCK_PATTERNS, just at a
different syntactic layer.

Two helpers added:
- extractNewFieldsWithLine: keeps each field's diff-line index so the
  caller can locate the parent struct.
- parentStructHasSerdeDerive: walks back ≤80 lines for a `pub struct`
  boundary, then ≤8 lines above it for `#[derive(...)]` lines
  containing Serialize or Deserialize. Stops on closing-brace-at-col-0
  to avoid escaping the enclosing scope.

Verified on PR #11's actual diff: unread-field warnings dropped from
8 → 0. Synthetic cases confirm the check still fires on plain
(non-serde) structs with no in-diff reader, so the
genuine-placeholder catch is preserved.

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"]}}
