# Review by Linus Torvalds (Round 1)

## Review Complete

**VERDICT: request-changes**

Two minor issues to fix before this ships:

1. **Dead code in tests** — `TestCleanWorkingTree` is defined twice in `test_sequential_implement.py`. The empty stub at line 992 ("Tests moved below; see TestTaskRetryLoop") is leftover from a refactor. Delete it.

2. **Incomplete safety net** — The defensive check at orchestrator.py line 1090 (`if not task_succeeded and task_id not in failed`) adds the task to `failed` but never populates `task_results[task_id]`. Every other failure path writes a result entry. If this code ever fires, anything iterating `task_results` will silently miss the task or KeyError.

**What's good**: The implementation is clean and minimal. Plain for-loop retry, no unnecessary abstractions. `_clean_working_tree()` is appropriately paranoid (logs warnings, never raises). Error truncation is simple string slicing. Test coverage is thorough and tests deterministic logic, not stochastic LLM behavior. The existing tests were correctly updated to explicitly disable retry (`max_task_retries=0`) to preserve their "fail immediately" semantics. All 218 tests pass with zero regressions.
