# Review by Linus Torvalds (Round 2)

## Review Complete — Linus Torvalds (Round 2)

**VERDICT: approve**

Both round 1 issues are fixed:

1. **Dead code removed** — the empty `TestCleanWorkingTree` stub in `test_sequential_implement.py` is gone.
2. **Safety net populates `task_results`** — `orchestrator.py` line 1090 now uses `setdefault` to write a proper failure entry without clobbering.

The implementation is clean and minimal. Plain for-loop retry, no unnecessary abstractions. `_clean_working_tree()` is properly defensive — catches exceptions, logs warnings, never raises. Error injection is simple string truncation. Existing tests correctly updated to `max_task_retries=0` to preserve their fail-immediately semantics. **218/218 tests pass**, zero regressions.

FINDINGS:
- [src/colonyos/orchestrator.py]: Round 1 safety-net fix correctly uses `setdefault` — avoids clobbering if result already exists
- [tests/test_sequential_implement.py]: Round 1 dead code stub removed cleanly

SYNTHESIS:
Both round 1 issues are fixed. The implementation is minimal, correct, and well-tested. The retry loop is a plain for-loop with no unnecessary abstractions. `_clean_working_tree()` is appropriately defensive. Error injection is simple truncation. Test coverage is thorough and tests deterministic behavior. 218/218 tests pass with zero regressions. This is ready to merge.
