 - [x] Task: Verify `litefs.yml` points to `entrypoint.sh` (should already be correct) (verified)
 - [x] Task: Conductor - User Manual Verification 'Phase 1: Container Environment Preparation' (Protocol in workflow.md)
 
-## Phase 2: Script Implementation [ ]
-- [ ] Task: Refactor `entrypoint.sh` with the TTL Heartbeat logic
-    - [ ] Implement `register_service` with TTL check definition
-    - [ ] Implement `pass_ttl` loop
-    - [ ] Implement robust `stop_app` and signal trapping
-    - [ ] Ensure correct Primary/Replica detection logic (LiteFS 0.5: Primary = No `.primary` file)
