# Task Review: - [x] 5.0 Implement fix loop in orchestrator `run()`

## Review Complete

The consolidated review has been saved to `cOS_reviews/20260317_review_fix_loop_task_5_0.md`.

### Verdict: **request-changes**

3 of 7 reviewers approved (Michael Seibel, Steve Jobs, Jony Ive); 4 requested changes (Systems Engineer, Linus Torvalds, Security Engineer, Karpathy). All 47 tests pass.

### 4 Blocking Issues

| # | Issue | Who Found It |
|---|-------|-------------|
| **1** | **Fix-loop review missing `allowed_tools`** — the re-review at line 695 doesn't pass `allowed_tools`, accidentally granting write access to the review agent during fix iterations. This contradicts commit `8d9b376` which explicitly restricted reviews to read-only. | Security Engineer |
| **2** | **Budget guard checks 1x `per_phase` instead of 3x** — a fix cycle runs fix + review + decision (3 phases), but the guard only checks for 1 phase worth of budget. This can enter iterations it can't afford. | Systems Engineer, Karpathy |
| **3** | **Missing `success` check on decision phase result** — fix phase and review phase both check `success` and break on failure, but the decision phase doesn't. A failed decision silently produces UNKNOWN and continues iterating. | Systems Engineer, Karpathy |
| **4** | **Misleading "iterations exhausted" log message** — when a phase fails mid-loop or budget runs out, the message still says "all N iterations exhausted" which is factually wrong. | Linus, Steve Jobs, Jony Ive |

### What's Working Well
- Clean architecture: the fix loop is a natural extension of the pipeline
- All FR requirements implemented (FR-1 through FR-9)
- Strong test coverage (8 fix-loop tests + 5 prompt tests)
- Backward-compatible: `max_fix_iterations=0` preserves fail-fast
- Iteration-tagged artifacts provide good audit trail
- Fix instruction template is well-scoped with the hybrid inline/reference approach
