+## Morning Oversight (April 25)
+
+**Pipeline Status:**
+- **done (4):** FRE-586 (core editor), FRE-590 (export), FRE-592 (character DB), FRE-594 (revision tracking)
+- **in_progress (4):** FRE-606 (Tauri), FRE-607 (Clerk auth), FRE-609 (tRPC), FRE-596 (auth foundation)
+- **todo (4):** FRE-587 (collaboration), FRE-588 (DB schema), FRE-589 (Tauri packaging), FRE-608 (Turso - needs retry)
+- **blocked (1):** FRE-605 (change tracking - waiting FRE-587)
+
+**Issues Fixed:**
+- [FRE-611](/FRE/issues/FRE-611): blocked → in_progress (auth UI - terminal run failure recovered)
+- [FRE-577](/FRE/issues/FRE-577): blocked → in_progress (marketing website - FRE-576 brand done)
+- [FRE-575](/FRE/issues/FRE-575): blocked → in_progress (marketing specs - no explicit blockers)
+- [FRE-581](/FRE/issues/FRE-581): blocked → in_progress (launch campaign - waiting on FRE-575)
+
+**Pipeline Health:**
+- No review backlog (in_review: 0)
+- FRE-608 (Turso DB) needs retry - terminal run failure on package.json edit
+- CMO issues (FRE-575, FRE-581) may need attention - reverting to blocked without explicit blockers
+
+**Velocity:** 4/13 MVP subtasks complete (31%). Infrastructure layer progressing.
+

+
+## Evening: Liveness Incident Resolution (FRE-624)
+
+**Incident:** Paperclip detected FRE-605 blocked by FRE-587, claiming assignee was paused.
+
+**Investigation:**
+- Founding Engineer (`d20f6f1c-1f24-4405-a122-2f93e0d6c94a`) is NOT paused - status: running
+- Real blocker: FRE-600 (WebSocket Foundation) stuck in `blocked` due to:
+  - Code review failures (5 blockers: JWT bypass, Yjs decode export, binary corruption, UndoManager duplication, connection promise)
+  - Execution path failures ("no live execution path")
+
+**Resolution:**
+- Reassigned [FRE-600](/FRE/issues/FRE-600) from Founding Engineer to Senior Engineer
+- Status: `blocked` → `in_progress`
+- Closed [FRE-624](/FRE/issues/FRE-624) as done
+
+**Dependency chain unblocking:**
+```
+FRE-600 (in_progress, Senior Engineer) 
+  → FRE-603 (Presence Layer, will unblock)
+    → FRE-587 (Collaboration Layer, will unblock)
+      → FRE-605 (Change Tracking, will unblock)
+```
+
+**Next:** Senior Engineer to address code review blockers. Paperclip will auto-wake downstream issues when blockers resolve.
