 # Session Log
 
+## Session 181 — 2026-03-15 19:00 UTC (Sunday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~17d uptime (896K+ seconds)
+- **Staging:** v0.5.2 ✅ healthy
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Full infrastructure verification** — All nodes Ready. Both prod and staging healthy. DB connected (PostgreSQL 17.4). Pool 15/15 available.
+  2. **Codebase review** — Zero TODOs/FIXMEs/HACKs in source. Clean code.
+  3. **Dependency audit** — npm audit: 0 vulnerabilities.
+  4. **Performance spot-check** — Production warm response: 0.34s for trivial PDF. Cold start (staging): ~4s (expected Chromium pool init). Landing page: 148ms.
+  5. **TypeScript strict check** — Zero errors.
+  6. **Source code review** — Reviewed convert, billing, keys, logger modules. All well-structured.
+- **Total tests:** 778 (all passing), 77 test files ✅
+- **Coverage:** Stmts 94%, Branches 90.61%, Functions 84.95%, Lines 94.5%
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent
+- **Investor test:** All 5 checks ✅
+- **Staging delta:** 94 commits ahead of production (v0.5.1)
+- **Assessment:** Product is fully mature. All meaningful audit angles exhausted across sessions 177-181. No actionable improvements found — code is clean, tests comprehensive, infrastructure stable. The only pending action is production tag for v0.5.2 (investor approval needed). Recommend reducing session frequency until there's investor direction or a support ticket.

+## Session 180 — 2026-03-15 16:00 UTC (Sunday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~17d uptime (896K+ seconds)
+- **Staging:** v0.5.2 ✅ healthy
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Full infrastructure verification** — All nodes Ready. Both prod and staging healthy. DB connected (PostgreSQL 17.4). Pool 15/15 available.
+  2. **Dependency audit** — npm audit: 0 vulnerabilities. npm outdated: 0 outdated.
+  3. **CORS audit** — API endpoints return proper CORS headers (`*` for API, dynamic allowlist for auth routes).
+  4. **Security headers audit** — CSP, HSTS, X-Frame-Options, Permissions-Policy, CORP all correct.
+  5. **Rate limiting audit** — All rate limits consistent and properly configured (100/min global, 5/hr demo, 3/hr email-change).
+  6. **OpenAPI spec audit** — All 15 paths documented. Deprecated signup/free properly marked.
+  7. **robots.txt + sitemap verified** — Correct.
+  8. **Coverage review** — Remaining gaps are server startup code (index.ts), type definitions, and dead-code error paths. Diminishing returns confirmed.
+- **Total tests:** 778 (all passing), 77 test files ✅
+- **Coverage:** Stmts 94%, Branches 90.61%, Functions 84.95%, Lines 94.5%
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent
+- **Investor test:** All 5 checks ✅
+- **Staging delta:** 94 commits ahead of production (v0.5.1)
+- **Assessment:** Product is in excellent shape. All audit angles (security, performance, accessibility, SEO, error handling, rate limiting, CORS, dependencies) are clean. Remaining coverage gaps are architectural (startup code, dead-code paths) — no further test work yields meaningful quality improvement. Ready for production tag whenever investor approves.
