The auditor's own audit on commit ebd9ab7 produced 10 kimi_architect
findings; 2 are real correctness issues that this commit lands. The
other 8 are documented in the commit body as triaged-skip with
rationale (false flags, defensible by current intent, or edge cases).
LANDED:
1. auditor/index.ts — atomic state mutation on audit count.
`state.audit_count_per_pr[prKey] += 1` was held in memory until
the cycle's saveState at the end. If the daemon was killed mid-
cycle (SIGTERM, OOM, panic), the count was lost on restart while
the on-disk last_audited still showed the SHA as audited — the cap
silently leaked one audit per crash. Fix: persist state immediately
after each successful audit so the increment survives a crash.
saveState is idempotent + cheap (single JSON write); per-audit
cost negligible.
2. auditor/checks/inference.ts — Number-coerce mode runner telemetry.
`body?.latency_ms ?? 0` collapses null/undefined but passes through
non-numeric values (string, NaN, etc.) which would poison downstream
arithmetic in maxLatencyMs computation. Added a `num(v)` helper
that does `Number(v)` with `isFinite` fallback to 0. Applied to
latency_ms, enriched_prompt_chars, bug_fingerprints_count,
matrix_chunks_kept.
SKIPPED with rationale:
- WARN kimi_architect.ts:211 "metrics appended even on empty verdict":
this is intentional — observability shouldn't depend on whether
parseFindings succeeded. Comment in the file explicitly notes this.
- WARN static.ts:270 "escaped-backslash-before-backtick edge case":
real but extremely narrow (Rust raw strings with `\\\\\``). No
observed false positives in production audits; defer.
- INFO kimi_architect.ts:333 "sync existsSync in async fn": existsSync
is non-blocking syscall on Linux; not a real perf hit at audit
scale (10s of findings per call).
- INFO kimi_architect.ts:105 "audit_index modulo wraparound at 50+
audits": cap=3 means we never reach high counts on any PR.
- INFO inference.ts:366 "prompt injection delimiter risk": OUTPUT
FORMAT delimiter is in our prompt template, not user input; user
data goes inside content sections that don't contain the delimiter.
- WARN Cargo.lock:8739 "truth+validator no Cargo.toml in diff":
false flag — Cargo.toml IS in workspace members (lines 17-18 of
the workspace manifest).
- WARN config/modes.toml:1 "no schema validation": defensible — the
load path validates structure (deserialize_string_or_vec at
mode.rs:175) and falls back to safe default on parse error.
- INFO evidence_record.ts:124 "metadata accepts any keys": values are
constrained to `string | number | boolean`; key-name validation
not warranted for a domain-metadata field.
The 13 BLOCK-severity inference findings on this audit are all
"claim not backed" against historical commit messages from earlier
in the branch (8aa7ee9, bc698eb, 5bdd159, etc.). Those are
aspirational prose ("Verified end-to-end") that the deepseek
consensus can't verify from a static diff — known limitation, not
actionable as code fixes.
Verification:
bun build auditor/index.ts compiles
bun build auditor/checks/inference.ts compiles
systemctl restart lakehouse-auditor active
Cap remains active on PR #11 (3/3) — daemon will not audit this
fix-commit. Reset state.audit_count_per_pr.11 to verify the fixes
land clean on a fresh audit when ready.
