-Goal: Audit prompt safety.
-Result: Audited 44 prompts. 44 safe, 0 need review.
+Goal: Audit codebase metrics (file size, innerHTML, lint).
+Result: Audit complete.
+- Oversized files: 20 new (6,413 excess lines). Top offender: `perf/constants-refactor/candidates.json` (1368 excess).
+- innerHTML: 6 assignments in 2 files (`landing/index.html`, `dashboard/index.html`).
+- Lint: Passed (0 errors, 42 warnings).
+- High-priority: Sanitize innerHTML in `landing/index.html`, decompose `src/lock-ops.mjs`.
