+## Session 47 — 2026-02-16 20:00 UTC (Monday Evening — Subagent)
+- **Server health:** UP, PostgreSQL 16.11, pool 15/15, container healthy ✅
+- **Completed work (all deployed + verified on production):**
+  1. ✅ **Audit #10 FIXED** — Usage DB writes now batched via write-behind buffer
+     - Dirty keys tracked in Set, flushed every 5s or when 50+ entries
+     - In-memory Map is source of truth, DB writes are async batch
+     - Eliminates per-request DB write under load
+  2. ✅ **Audit #12 FIXED** — Cache divergence handled with retry logic
+     - Failed DB writes stay in dirty set for retry (max 3 attempts)
+     - Critical log warning after max retries exhausted
+     - Graceful SIGTERM/SIGINT flush on shutdown
+  3. ✅ **Audit #15 FIXED** — Per-key queue fairness in PDF concurrency
+     - Each API key limited to 3 queued items in concurrency queue
+     - Prevents single key from monopolizing all queue slots
+     - Returns 429 immediately when per-key limit reached
+  4. ✅ **Support ticket #369** — Replied to "lost api key" from dominik@superbros.tv
+     - Directed to self-service key recovery on website
+     - Fixed FreeScout support tool (API needed `text` + `user` fields)
+  5. ✅ **Git:** Commit e7d28bc pushed to Forgejo
+- **Investor Test:**
+  1. Trust with money? **Yes** ✅
+  2. Data loss? **Protected** ✅ — Local + off-site BorgBackup
+  3. Free tier abuse? **Mitigated** ✅
+  4. Key recovery? **Yes** ✅
+  5. False features? **Clean** ✅
+- **Budget:** €181.71 remaining, Revenue: €9
+- **Open bugs:** 0 CRITICAL, 1 HIGH (BUG-049 — investor action), 0 MEDIUM, 2 LOW (#18, #25)
+- **Blockers:** BUG-049 requires investor to enable Stripe invoice emails in Dashboard
