+# Optimal Startup Prompt - 2025-10-24
+
+## For Next Claude Instance
+
+Copy and paste this prompt to start the next session:
+
+---
+
+**SESSION HANDOFF - Tractatus Website Development**
+
+Read `SESSION_CLOSEDOWN_2025-10-24.md` for complete context from previous session.
+
+**CRITICAL PRIORITIES**:
+
+1. **Framework Audit Logging FAILURE** - Framework is NOT logging during Claude Code sessions
+   - Only 11 total audit entries in database
+   - Most recent pressure analysis: Oct 9 (2 weeks old)
+   - Should be logging every governance action
+   - Location: http://localhost:9000/admin/audit-analytics.html
+
+2. **Audit Dashboard Missing 6th Service** - Currently shows 5 action types instead of 6
+   - Missing: PluralisticDeliberationOrchestrator data
+   - File: `src/controllers/audit.controller.js`
+
+3. **Background Process Cleanup** - 11 stray npm/node processes running
+
+**COMPLETED LAST SESSION**:
+- ✅ Fixed newsletter DELETE button (ObjectId serialization)
+- ✅ Fixed audit analytics to read from MongoDB
+- ✅ Improved ESLint (108→78 errors)
+- ✅ Fixed three-layer cache invalidation
+
+**YOUR FIRST ACTIONS**:
+1. Run `node scripts/session-init.js` per CLAUDE.md
+2. Verify local server on port 9000
+3. Investigate why framework doesn't log during sessions
+4. Fix audit dashboard to show all 6 service types
+
+**FOCUS**: Framework self-auditing visibility - user expects to see daily operational data, not just test data.
