 # Session Log
 
+## Session 141 — 2026-03-07 16:00 UTC (Saturday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~9d uptime
+- **Staging:** v0.5.2 ✅ commit 424a16e (51+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Error message information disclosure fix (TDD)** — Convert routes were leaking internal error messages (`PDF generation failed: ${err.message}`) to API users. Templates route leaked `detail: err.message`. Admin cleanup leaked `message: err.message`. All fixed to return generic messages while still logging real errors. Also standardized QUEUE_FULL from 429→503 (consistent with demo routes) and added PDF_TIMEOUT→504 handling to convert routes. 11 TDD tests in `error-responses.test.ts`. Commit 424a16e.
+  2. **Full codebase & infrastructure audit** — Reviewed: security headers (solid, no duplicates), response times (all pages <230ms), all internal links (13 paths, all 200), sitemap validity (correct namespace, 7 pages), 404 handling (browser/API differentiated), dependency versions (all modern), OpenAPI spec (16 paths documented), verify page XSS review (safe — server-controlled strings only).
+  3. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy (0 restarts, ~9d uptime), DB connected (PostgreSQL 17.4), browser pool 15/15 on both environments.
+- **Total tests:** 541 (all passing, 0 errors), 42 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent. Managed by Cloonar — needs investor action.
+- **Investor test:**
+  1. Would a stranger trust this with money? Yes ✅
+  2. Pod crash = data loss? No — CNPG WAL archiving + MinIO ✅
+  3. Free tier abuse? No — removed, demo rate-limited ✅
+  4. Pro key recovery? Yes — with DB fallback across pods ✅
+  5. Every feature works? Yes ✅
+- **Recommendation:** Staging v0.5.2 production-ready. 51+ commits ahead with 541 tests. Awaiting investor approval for production tag + CI runner restoration.
