# Review by Linus Torvalds (Round 4)

---

**Review complete.** 135 tests pass across `test_slack_formatting.py` and `test_sanitize.py`. All 5 functional requirements implemented. 10 commits, +1,333 / -23 lines.

VERDICT: **approve**

FINDINGS:
- **[src/colonyos/orchestrator.py]**: `_extract_review_findings_summary` blank-line handling is slightly loose — continues collecting past blank lines until a non-finding line. Not triggered by actual review template output. Non-blocking.
- **[src/colonyos/orchestrator.py]**: `_format_task_list_with_descriptions` silently swallows `ValueError`/`TypeError` on cost/duration formatting — a `logger.debug` would aid debugging. Non-blocking.

SYNTHESIS:
This is good, clean work. The data structures are right — task descriptions and review findings extracted from existing artifacts with simple string operations, no regex gymnastics, no new LLM calls, no clever abstractions. The three-tier fallback in `_extract_review_findings_summary()` handles real-world variance without overengineering. Sanitization is applied at the content boundary with double-layer defense. Named constants make limits grep-able. 135 tests cover formatting, sanitization, and constants. All prior round findings addressed cleanly. Ship it.
