+## Session 37 — 2026-02-16 08:27 UTC (Monday Morning)
+- **CRITICAL FINDING: Container was DOWN** — discovered during health check. Exit 137 (SIGKILL), marked "hasBeenManuallyStopped=true". Likely killed by a sub-agent in previous session and never restarted. Unknown downtime duration.
+- **Restarted container** — app back up, health check passes, PostgreSQL 16.11, 49 keys loaded, 15 browser pages available.
+- **Previous session (36) improvements already deployed** (discovered via session review):
+  - Structured logging with pino + request IDs (X-Request-Id header)
+  - PDF generation 30s timeout + memory leak fixes (verification + rate limit cleanup intervals)
+  - Compression middleware (gzip)
+  - Static asset caching (1h maxAge + etag)
+  - Template currency XSS fix
+  - Docker Compose cleanup (removed deprecated version field)
+  - SEO: OG/Twitter meta tags, robots.txt, sitemap.xml, OG image (1200x630 PNG)
+  - Accessibility: ARIA labels, focus-visible styles, escape key closes modals, focus trapping, aria-live regions
+- **Spawned Backend Dev** for nginx optimization (gzip, caching headers) + log rotation — still running
+- **Spawned QA Tester** for full regression after downtime — still running
+- **Attempted uptime monitoring cron** — gateway timeout, will retry
+- **Investor Test:**
+  1. Trust with money? **Almost** — all code deployed, needs real E2E test payment
+  2. Data loss? **Mitigated** — BorgBackup daily, local only. Container downtime went undetected = monitoring gap.
+  3. Free tier abuse? **Mitigated** ✅
+  4. Key recovery? **Yes** ✅
+  5. False features? **Clean** ✅
+- **Budget:** €181.71 remaining, Revenue: €0
+- **Status:** NOT launch-ready. Container was down undetected. Sub-agents still running.
+- **Blockers (investor-dependent, unchanged):**
+  1. E2E Pro payment test (real $9 Stripe payment)
+  2. 3 Forgejo repo secrets for CI/CD
+  3. Hetzner Storage Box (~€3/mo) for off-site backups
+- **New concern:** No monitoring/alerting — downtime went undetected. Need uptime check.
+- **UPDATE 08:38 UTC:** QA complete — 10/10 PASS ✅. Zero issues after container restart. All flows verified (signup, Stripe, /docs, mobile, health, API errors).
+- **UPDATE:** Backend Dev still running (Docker ARM rebuild). Will announce nginx + log rotation results when complete.
+- **UPDATE:** Uptime monitoring cron failed twice (gateway timeout). Flagged for main session.
+
+## Session 38 — 2026-02-16 08:33 UTC (Monday Morning — Cron)
+- **Server health:** UP, PostgreSQL 16.11, pool 15/15. Container was restarted by previous session's backend dev.
+- **CODE AUDIT FINDING:** BUG-040 — SSRF vulnerability in URL→PDF endpoint (HIGH severity). Only validates protocol, does NOT block private/internal IPs. Attacker could access cloud metadata, internal services, RFC1918 addresses.
+- **Sub-agents spawned:**
+  1. Backend Dev — nginx warning fix, log rotation, version mismatch
+  2. Monitor Setup — uptime monitoring script + cron on server (every 5 min)
+  3. SSRF Fix — DNS-level private IP blocking for URL→PDF endpoint
+- **Investor Test:**
+  1. Trust with money? **NO** — SSRF vulnerability allows internal network scanning
+  2. Data loss? **Mitigated** — BorgBackup daily, local only
+  3. Free tier abuse? **Mitigated** ✅
+  4. Key recovery? **Yes** ✅
+  5. False features? **Clean** ✅
+- **LAUNCH BLOCKED:** HIGH severity SSRF bug must be fixed first. Investor requested launch but security comes first.
+- **Note:** Main session also spawned docfast-ceo-session38 in response to investor's "launch now + approve storage box". Deferring report to that session to avoid duplicate.
+- **Budget:** €181.71 remaining, Revenue: €0
+- **Status:** NOT launch-ready. HIGH severity security bug open.
