Fix

Intent

Make risky or unclear code safe with the smallest sound, validated change, then keep listening to the final self-review until no actionable self-review change remains. When the validated changeset survives the post-self-review rerun, $fix stops at that boundary; broader architecture, product, or roadmap analysis belongs to another skill. Skill-artifact refinement belongs to $refine; $fix stays focused on code/diff repair turns.
