+## BUG-112: No global Express error handler + unprotected async routes in recover & email-change
+- **Date:** 2026-03-17
+- **Severity:** MEDIUM
+- **Issue:** The Express app has no global error-handling middleware (`(err, req, res, next)` 4-arg handler). Additionally, `src/routes/recover.ts` and `src/routes/email-change.ts` have async handlers with multiple `await` calls but zero try/catch blocks. If `queryWithRetry`, `verifyCode`, or `createPendingVerification` throws unexpectedly, the error propagates unhandled — Express may send its default HTML error page (leaking stack traces) or the request hangs.
+- **Impact:** In DB failure scenarios, users see ugly error pages instead of clean JSON errors. Potential stack trace leakage.
+- **Fix:** Add global Express error-handling middleware + wrap recover and email-change handlers in try/catch.
+- **Status:** ✅ FIXED — pushed to main (a3bba8f), 788 tests passing, staging deployment pending CI

 # Session Log
 
+## Session 190 — 2026-03-17 17:00 CET (Tuesday Evening)
+- **Audit:** Proactive codebase audit found missing global Express error handler + unprotected async routes
+- **BUG-112:** `recover.ts` and `email-change.ts` had async handlers with zero try/catch — DB failures would propagate unhandled. No global `(err, req, res, next)` middleware existed.
+- **Fix (TDD):** Sub-agent wrote 10 new failing tests (RED), then implemented:
+  1. Global Express error handler in `index.ts` (handles SyntaxError→400, everything else→500, JSON for API routes, text for pages)
+  2. try/catch in all 4 handlers across `recover.ts` and `email-change.ts`
+- **Results:** 788 tests passing (was 778), 77 test files. Pushed as commit a3bba8f.
+- **Staging:** CI pipeline triggered, deployment pending build completion.
+- **Status:** All systems healthy. Production v0.5.1, staging v0.5.2.
+
+## Session 189 — 2026-03-17 14:00 CET (Tuesday Afternoon)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, 19d+ uptime
+- **Staging:** v0.5.2 ✅ healthy, 1 replica, 2d20h uptime
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Full test coverage audit** — Ran vitest with v8 coverage: 94% statements, 90.6% branches, 85% functions, 94.5% lines. Gaps are in browser lifecycle functions (initBrowser/closeBrowser/launchInstance — require real Chromium) and index.ts app startup code. No actionable coverage gaps found.
+  2. **Code quality audit** — Zero TODO/FIXME/HACK comments. Zero TypeScript errors. Zero npm audit vulnerabilities. Clean production logs (no errors/warnings on either pod).
+  3. **Security headers verified** — CSP, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, X-Content-Type-Options all present and properly configured.
+  4. **Performance check** — Landing page 177ms, docs 168ms, examples 152ms. All fast.
+- **Total tests:** 778 (all passing) ✅
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent
+- **Investor test:** All 5 checks ✅
+- **Staging delta:** 95 commits ahead of production (v0.5.1)
+- **Assessment:** Deep audit found no issues. Code quality excellent. Product fully stable. Staging v0.5.2 ready for production tag whenever investor approves.

+## Session 188 — 2026-03-17 11:00 CET (Tuesday Midday)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, 19d+ uptime (1M+ seconds)
+- **Staging:** v0.5.2 ✅ healthy, 1 replica, 2d17h uptime
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Dependency maintenance** — Updated nanoid 5.1.6→5.1.7, terser 5.46.0→5.46.1. All 778 tests pass. Commit 2dfb0ac pushed to main. npm audit 0 vulns, npm outdated 0.
+  2. **Full infrastructure verification** — All 11 endpoints returning 200. DB connected (PostgreSQL 17.4). Pool 15/15 available.
+  3. **Link audit** — All pages (/, /docs, /examples, /status, /impressum, /privacy, /terms, /health, /openapi.json, /sitemap.xml, /robots.txt) returning 200.
+  4. **OpenAPI spec verified** — 15 endpoints, all documented.
+  5. **Staging noindex verified** — x-robots-tag: noindex, nofollow header present.
+- **Total tests:** 778 (all passing) ✅
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent (staging won't auto-deploy new commit)
+- **Investor test:** All 5 checks ✅
+- **Staging delta:** 95 commits ahead of production (v0.5.1)
+- **Assessment:** Product fully stable. Patch deps updated. Staging v0.5.2 ready for production tag whenever investor approves.
