fix

End-to-end bug-fix pipeline that diagnoses, implements, and proves the fix. It orchestrates /root-cause, /debugging-difficult-bugs, /test, and /check-and-commit, and performs the fix itself — the minimal code change from the proven cause plus a mandatory red→green regression test and scoped validation gates. At start it picks an autonomy mode (approval-before-each-phase vs fully autonomous) and a phase set (root-cause + fix are mandatory; runtime instrumentation is conditional on confidence, test is optional, commit runs only on explicit ask), auto-detected from the request and confirmed with the user when unclear. Keeps a structured run record at .ai/runs/{date}-{slug}.md. Use when fixing a bug, test failure, or unexpected behavior ("fix this bug", "why does X fail"). Do not use for building new features (use /feature). For a single watched item with explicit acceptance criteria, prefer /conductor.
