# Fix Dead-End Phases

## Problem
- `decomposition:approved` has `[]` in LEGAL_TRANSITIONS (status.py:91). Parent tasks stuck forever.
- `human_intervention` not in LEGAL_TRANSITIONS at all. Referee can transition into it but never out.

## Fix
1. Add `decomposition:approved → [complete]` to LEGAL_TRANSITIONS (parent task completes when all subtasks done)
2. Add `human_intervention → [referee, complete]` to LEGAL_TRANSITIONS (user can send back to referee or mark complete)

## Verification
- `status.py --transition complete --task <t> --project .` on a decomposition:approved task should succeed
- `status.py --transition referee --task <t> --project .` on a human_intervention task should succeed
