# IMPLEMENTATION.md — Fix Dead-End Phases

## Changes Made
- `scripts/status.py:91`: Changed `"decomposition:approved": []` to `"decomposition:approved": ["complete"]`
- `scripts/status.py:103`: Added `"human_intervention": ["referee", "complete"]` to LEGAL_TRANSITIONS

## How It Works
- Parent tasks at decomposition:approved can now transition to complete (after sub-tasks finish)
- Human intervention tasks can transition back to referee or to complete
- Verified both transitions are legal via status.py --transition
