Code Review

Review the diff from a user-supplied fixed point against:

• Standards — accepted engineering/architecture guidance and repository standards.
• Spec — the selected backlog item's desired delta and acceptance criteria within Epic context.

Use one combined reviewer by default. Use independent parallel Standards and Spec reviewers only for security/authentication, destructive migration or credible data-loss risk, or public API compatibility. The wiki is accepted current state; the backlog is desired change.

When split review applies, invoke $parallel-execution with two read-only judgement units. This context owns authority resolution, synthesis, findings, and the handoff. A combined review uses one reviewer without loading the shared scheduler.

Under a depth-one provisional worker, never spawn: execute the selected brief or briefs locally, sequence split axes, and report the missing parallel capacity.

Process

1. Pin the fixed point

Use whatever the user gave (SHA, branch, tag, main, HEAD~5); ask if unspecified. Resolve before authority discovery with git rev-parse --verify <fixed-point>^{commit} and git merge-base <fixed-point> HEAD; stop with an actionable error if either fails. Capture once:
