# Decision Gate: Task-Level Retry for Auto-Recovery

**Branch**: `colonyos/recovery-b69f562da7`
**PRD**: `cOS_prds/20260402_022155_prd_you_are_a_code_assistant_working_on_behalf_of_the_engineering_team_the_following.md`
**Date**: 2026-04-02

## Persona Verdicts

| Persona | Round | Verdict |
|---------|-------|---------|
| Linus Torvalds | Round 1 | request-changes |
| Linus Torvalds | Round 2 | **approve** |
| Staff Security Engineer | Round 1 | **approve** |
| Staff Security Engineer | Round 2 | **approve** |
| Andrej Karpathy | Round 1 | **approve** |
| Andrej Karpathy | Round 2 | **approve** |
| Principal Systems Engineer | Round 1 | **approve** |

**Tally**: 6 approve / 0 request-changes (across latest rounds: 4/4 unanimous approve)

## Test Results

- **218/218 tests pass** (22 new + 196 existing, zero regressions)
- Verified on branch at decision time

## PRD Requirement Coverage

| Requirement | Status |
|-------------|--------|
| FR-1: `max_task_retries` in `RecoveryConfig` | ✅ |
| FR-2: `previous_error` param in prompt builder | ✅ |
| FR-3: `_clean_working_tree()` helper | ✅ |
| FR-4: Retry loop in `_run_sequential_implement()` | ✅ |
| FR-5: `task_retry` recovery event logging | ✅ |
| FR-6: Parse/validate in `_parse_recovery_config()` | ✅ |

All 6 functional requirements are implemented and tested.

## Findings Summary

- **CRITICAL**: None
- **HIGH**: 2 found in Round 1 (dead test code, safety-net missing `task_results`). Both fixed in Round 2.
- **MEDIUM**: None
- **LOW**: 4 non-blocking items across reviewers (all deferred to follow-up):
  - `_drain_injected_context()` may empty context on retry (cosmetic)
  - No upper ceiling on `max_task_retries` (recommend cap at 3 in follow-up)
  - Error messages truncated but not sanitized before prompt injection (acceptable for v1)
  - Recovery event naming ambiguity (`success: False` logged at retry time, not at outcome)

```
VERDICT: GO
```

### Rationale
All 4 personas approve unanimously in their latest rounds. The two HIGH findings from Linus Torvalds' Round 1 (dead test stub, safety-net `task_results` gap) are confirmed fixed in Round 2. All 6 PRD functional requirements are implemented and covered by 22 new unit tests. 218/218 tests pass with zero regressions. The remaining LOW findings are non-blocking polish items suitable for a follow-up iteration.

### Unresolved Issues
(None blocking merge)

### Recommendation
Merge as-is. Consider a follow-up to add a `max_task_retries` ceiling (cap at 3) and basic error sanitization before prompt injection, as recommended by the security and systems engineering reviewers.
