Verify that the implementation completes the linked issue or PR goal and remains strictly limited to that goal. It must not add unnecessary functionality or introduce new bugs, regression risk, permission or security risk, or maintenance risk. A missing-goal finding must cite a concrete unmet requirement. A scope finding must identify the unrelated change and concrete risk. Necessary supporting work is not scope creep. Return schemaVersion 1, a coverage receipt for all changed files, and findings matching the supplied contract.
