+## Scattermind → Ranker bridge
+
+Ranker's continuation job is narrow:
+
+`Snapshot / Concept Map → candidate feature/action set → Rank-ready build order`
+
+`POST /api/rank-feedback` accepts a `prioritix-feature-set-v1`-style payload from Scattermind and returns ranked items plus `buildOrder.doFirst / validateNext / defer / park`. Keep this contract action-first; do not use it as a reason to add generic dashboard, auth, billing, or workspace layers before the bridge has proof.
+
+Recommended payload shape:
