scope-change-gate

Tags a diff by file and hunk, resolves which quality practices the change makes relevant, verifies coverage of changed lines and the recorded intent, and returns severity-ranked findings with remediation briefs. Use when a pull request is about to merge, when deciding what a change needs tested, or when a diff touches auth, schemas, migrations, or removes tests or guards. For only drafting the missing rationale, use the record-change-intent command; for a manual retest pack, use the regression-scope command.
