Cross-Modal Review

Convention: see conventions/cross-modal.yaml for the review pairs and refusal routing chain.

Relationship to gbrain eval cross-modal: This skill is the manual mid-flow gate (one model reviews work product before commit, with refusal routing). The gbrain eval cross-modal command (v0.27.x) is a sibling surface: 3 different-provider frontier models score-and-iterate on a documented dimension list before tests cement behavior. Use this skill for ad-hoc second opinions; use gbrain eval cross-modal for the skillify Phase 3 quality gate. The two are complementary, not redundant.
