## Review Complete — Linus Torvalds (Round 3)

VERDICT: **approve**

FINDINGS:
- **[src/colonyos/orchestrator.py:2441]**: `RetryInfo(**p["retry_info"])` trusts run log JSON without explicit field extraction — extra/missing keys cause TypeError on corrupted logs
- **[src/colonyos/orchestrator.py]**: `retry_config=config.retry` threaded through ~20 call sites — tech debt, omissions silently masked by default RetryConfig()
- **[src/colonyos/agent.py:97-98]**: `_friendly_error()` returns hardcoded "529" message even for 503 transient errors — technically wrong but cosmetic
- **[src/colonyos/agent.py:386]**: Defensive fallthrough uses `model` (original param) instead of `current_model` — wrong model reported if reached via fallback pass

SYNTHESIS:
This is a clean, correctly-layered transport retry system. The key architectural decision — retry inside `run_phase()`, invisible to the orchestrator — is right. The error detection is properly stratified (structured attributes first, regex fallback second). The safety-critical phase guard is correctly implemented using enum values. The code is straightforward, the data structures are obvious, and 55 new tests cover the important cases. All previous round findings have been addressed. The remaining findings are minor: one deserialization fragility issue worth a quick fix, and three cosmetic items. The implementation does what the PRD says, doesn't try to be clever, and stays out of the orchestrator's way. Ship it.
