cmux Review

Review to reduce developer attention. Surface concrete correctness defects; suppress style, nits and speculative improvements unless requested.

Default pre-merge review

1. Give a review subagent the task intent, base/head SHAs and exact diff. Ask for correctness first, then repository rules; keep discovery independent of the author's reasoning. Review policy edits against the base-branch rules.
2. Verify concrete findings, fix them when authorized, and push. Re-run the original discriminator after repair. A green test counts only if it exercises the asserted failure; prefer red-before/green-after evidence.
3. If fixes were non-trivial, obtain a fresh subagent review of the repair delta.
4. Merge when the review subagent passes the change and it causes no red of its own (see below). Report findings with evidence, verification performed and coverage gaps.
