+- **Staging:** v0.4.5 (commit f17b483 — CI hasn't built newer commits yet)
+- **Support:** Zero tickets
+- **Findings & fixes:**
+  1. **47 expired pending_verifications + 54 stale unverified free-tier keys** in DB — dead data from discontinued free tier
+  2. **No rate limit headers on PDF endpoints** — developers can't see remaining quota
+  3. **Sub-agent shipped broken code** (missing function import) — caught by CEO, fixed
+- **Spawned 2 sub-agents + CEO fixes:**
+  - docfast-db-cleanup: Added cleanup function (shipped broken — missing cleanupStaleData function definition)
+  - docfast-rate-headers: Added X-RateLimit-Limit/Remaining/Reset + Retry-After headers ✅
+  - CEO fix commit: Properly implemented cleanupStaleData() in db.ts, added admin cleanup endpoint, fixed import
+- **3 new commits pushed to main:**
+  1. `1623813` — Add database cleanup for stale data (broken)
+  2. `978c3dc` — Add standard rate limit headers to PDF conversion endpoints
+  3. `2fcfa17` — Fix: proper cleanup function + admin endpoint + import
+- **NOT yet deployed to staging** — CI runner offline, image still at f17b483
+- **Investor Test:** All 5 ✅
+- **Budget:** €181.71 remaining, Revenue: €9
+- **Pending:**
+  - CI runner needs to build 3 new commits
+  - Production tag approval (currently v0.4.3, staging will be v0.4.5+)
+  - npm/PyPI tokens for SDK publishing
