# Review by Linus Torvalds (Round 3)

VERDICT: approve

FINDINGS:
- [src/colonyos/sanitize.py]: `_SLACK_BARE_LINK_RE` only matches `https?://` schemes but `_SLACK_LINK_INJECTION_RE` covers arbitrary schemes — a `<slack://deep-link>` bare link (no pipe) bypasses the bare link regex and leaves angle brackets in the output. Low risk since such bare links would need to survive `sanitize_untrusted_content()` first, but the asymmetry is sloppy.
- [src/colonyos/orchestrator.py]: Phase header description truncation uses hardcoded `60`/`57` instead of `_SLACK_TASK_DESC_MAX` (72). The rest of the codebase correctly uses the named constant. Pick one number and use the damn constant.
- [src/colonyos/orchestrator.py]: `_extract_review_findings_summary` — blank-line handling inside the FINDINGS parser (`continue` on empty lines) means a review with blank lines between findings followed by prose will keep collecting. The state machine is slightly loose, though the review template doesn't produce this in practice.
- [src/colonyos/orchestrator.py]: `_format_task_list_with_descriptions` silently swallows `ValueError`/`TypeError` on cost/duration formatting. A `logger.debug` would cost nothing and save future debugging time.

SYNTHESIS:
This is clean, straightforward work. The data structures are right: task descriptions and review findings are 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()` (FINDINGS → SYNTHESIS → first line) handles real-world variance without overengineering. Sanitization is applied at the content boundary, not the output boundary, which is the correct architecture. The named constants (`_SLACK_MAX_CHARS`, `_SLACK_MAX_SHOWN_TASKS`, etc.) make the truncation limits grep-able. The test coverage is solid — 131 tests covering the formatting functions, sanitization edge cases, and constant values. The code does what it says, says what it does, and doesn't try to be clever. Ship it.
