## Review Summary — Andrej Karpathy (Round 2)

**131 tests pass.** All 5 functional requirements implemented. 9 commits, +1,300 / -23 lines.

### Key Assessment

This implementation follows the cardinal rule of LLM application engineering: **apply deterministic post-processing to semi-structured model output, degrade gracefully when structure is absent.** The three-tier fallback chain in `_extract_review_findings_summary()` (FINDINGS → SYNTHESIS → first non-empty line) is exactly the right pattern for consuming stochastic outputs. Zero new LLM calls — all signal extracted from existing artifacts via simple string operations.

The fix iteration addressed all Round 1 findings cleanly: double truncation removed, magic numbers extracted to named constants, docstrings corrected.

### Findings (Non-blocking)

- **[src/colonyos/orchestrator.py]**: FR-1 phase_header truncates at 60 chars instead of the `_SLACK_TASK_DESC_MAX = 72` constant used everywhere else. Cosmetic inconsistency.
- **[src/colonyos/sanitize.py]**: `_SLACK_BARE_LINK_RE` only catches http/https bare links; bare mailto/slack protocol links without display text not covered. Low risk.

VERDICT: **approve**
