 # Session Log
 
+## Session 146 — 2026-03-08 16:00 UTC (Sunday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~10d uptime
+- **Staging:** v0.5.2 ✅ commit b70ed49 (57+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Staging noindex protection (TDD)** — Staging site had NO protection against search engine indexing — same robots.txt as production, no `X-Robots-Tag`, no `noindex` meta. Google could index `staging.docfast.dev` creating duplicate content issues. Added middleware that sets `X-Robots-Tag: noindex, nofollow` when hostname contains "staging". 3 TDD tests (staging gets header, production doesn't, applies to API routes too). Commit b70ed49.
+  2. **Dead code cleanup** — Removed empty `// Email verification endpoint` comment residue from index.ts. 1 TDD test. Same commit.
+  3. **Codebase audit** — Reviewed: 404 page (branded, works for both HTML and API), OpenAPI spec (15 paths, signup properly deprecated with 410), all endpoints healthy (<165ms), no TODOs/FIXMEs, npm audit clean.
+- **Total tests:** 562 (all passing, 0 errors), 49 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push doesn't trigger staging redeploy. 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. 57+ commits ahead with 562 tests. Awaiting CI runner restoration + investor approval for production tag.

+## Session 145 — 2026-03-08 13:00 UTC (Sunday Afternoon)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~10d uptime
+- **Staging:** v0.5.2 ✅ commit 7206cb5 (56+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Dead code removal: signup router + legacy verification (TDD)** — Removed entire dead signup router (`src/routes/signup.ts`) — was never mounted since free tier removal (410 handler in index.ts stays). Removed `isEmailVerified()` and `getVerifiedApiKey()` from verification.ts (only callers were in dead signup router). Removed stale-key cleanup from `cleanupStaleData()` that queried legacy `verifications` table (no active code writes to it since session 143). Updated usage middleware message from "Free tier limit" to "Account limit". 8 new TDD tests added, signup.test.ts removed. Net -229 lines. Commit 7206cb5.
+  2. **Full infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy (0 restarts, ~10d uptime), DB connected (PostgreSQL 17.4), browser pool 15/15. All 12 endpoints returning 200 in <165ms. Sitemap valid, robots.txt correct.
+  3. **Sub-agent platform issue** — Sub-agent spawn failed instantly (same issue as session 142). Implemented changes directly.
+- **Total tests:** 556 (all passing, 0 errors), 48 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push doesn't trigger staging redeploy. Needs investor action.

+## Session 144 — 2026-03-08 10:00 UTC (Sunday Morning)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~10d uptime
+- **Staging:** v0.5.2 ✅ commit 9215627 (55+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Dependency updates** — Updated pg 8.19→8.20, puppeteer 24.37→24.38, stripe 20.4.0→20.4.1, @types/node 22.19.13→22.19.15. npm audit: 0 vulnerabilities. All 559 tests passing. Commit da57f57.
+  2. **Multi-stage Dockerfile (TDD)** — Optimized Dockerfile from single-stage to multi-stage build. Stage 1 (builder): installs all deps, compiles TypeScript, generates OpenAPI, builds HTML. Stage 2 (production): fresh slim image, Chromium + production deps only. Final image excludes: TypeScript source, tsconfig, dev deps, build scripts. 2 TDD tests added (dist/index.js exists, public/index.html exists). Commit 9215627.
+  3. **Bug tracker cleanup** — Updated BUG-108 status to FIXED (was marked OPEN despite being fixed in session 142). Added FIXED status to BUG-096 (effectively resolved by BUG-102 fix).
+  4. **Full audit** — All 11 pages/endpoints returning 200, sitemap valid (7 pages, correct namespace), security headers clean (no duplicates), structured data present, no accessibility regressions, npm audit clean.
+- **Total tests:** 561 (all passing, 0 errors), 46 test files
+- **Open bugs:** ZERO 🎉
