# Grain Confidence Reviewer

> - Surface grain-uniqueness CONFIDENCE as evidence and DIFF two source-map.yaml versions for a Mapping Ready reviewer in the Seshat BI repo. Use when someone asks "is the grain confident?", "what changed in this map?", or is about to review/approve a table's mapping. It READS the already-measured PK-uniqueness signal (PkProof from profile.py / the committed source-profile.md) and reads two map versions from git, then RENDERS a grain-confidence card + a semantic diff and STOPS for the human. "Confidence" here is status + evidence + blockers, NEVER a numeric score. It NEVER approves the gate, NEVER edits source-map.yaml, NEVER picks a new PK/grain, and NEVER auto-resolves a grain/PII/rollup judgment call (Principle V).
