+## Summary
+
+CODE-09 comment purge applied across all Phase 9 files and retroactively to Phase 8 backend sub-packages. WHAT comments (generic docstrings, inline labels, section headers) removed. WHY comments preserved per D-16: security invariants, non-obvious constraints, decision references (D-08/D-09/D-10/D-16/D-17), the api_key write-only invariant, and the NO-prefix anchor comments in all three __init__.py files.
+

+## Test Results
+
+- Backend: 413 passed, 1 pre-existing failure (unrelated ModuleNotFoundError), 6 skipped, 7 xfailed
+- Frontend: 137 passed (16 test files), 0 failures
+- Build: `npm run build` succeeds, 254 kB bundle
+
+## Self-Check: PASSED
+
+All D-16 must-preserves confirmed present:
+- `# NO prefix — parent __init__.py carries /api/admin (D-02)` in overview.py ✓
+- `api_key: ''  // write-only: never pre-filled from server` in AdminAiView.vue ✓
+- Router guard WHY block (D-09/D-10a comments) in index.js ✓
+- `<!-- Stay signed in checkbox (D-12) -->` in LoginView.vue ✓
+- `<!-- Daily exports section (D-17, C-4) -->` in AdminAuditView.vue ✓
