Implement real supervisor-driven auto-recovery
Orchestrator changes:
- Force-spawn GAMMA on iteration_limit before abort
- GAMMA.synthesize() creates emergency handoff payload
- loadRecoveryContext() logs "Resuming from {task_id} handoff"
- POST to /api/pipeline/log for resume message visibility
AgentGamma changes:
- Add synthesize() method for emergency abort synthesis
- Merges existing proposals into coherent handoff
- Stores as synthesis_type: "abort_recovery"
Server changes:
- Add POST /api/pipeline/log endpoint for orchestrator logging
- Recovery pipeline properly inherits GAMMA synthesis
Test coverage:
- test_auto_recovery.py: 6 unit tests
- test_e2e_auto_recovery.py: 5 E2E tests
- test_supervisor_recovery.py: 3 supervisor tests
- Success on attempt 2 (recovery works)
- Max failures (3 retries then FAILED)
- Success on attempt 1 (no recovery needed)
Recovery flow:
1. iteration_limit triggers
2. GAMMA force-spawned for emergency synthesis
3. Handoff dumped with GAMMA synthesis
4. Exit code 3 triggers auto-recovery
5. Recovery pipeline loads handoff
6. Logs "Resuming from {prior_pipeline} handoff"
7. Repeat up to 3 times or until success

Supervisor Recovery Test
|
||||
|
||||
Tests the complete supervisor-driven auto-recovery flow:
|
||||
1. Start a pipeline
|
||||
2. Force iteration_limit to trigger abort
|
||||
3. Verify GAMMA synthesizes proposals before handoff
|
||||
4. Verify supervisor spawns recovery pipeline
|
||||
5. Verify recovery pipeline loads handoff with resume message
|
||||
6. Track all retries until success or max failures
|
||||
|
||||
Run with: python3 tests/test_supervisor_recovery.py
|
||||
Requires: UI server running on localhost:3000
