# Source Mapping

> - Drive a raw retail source table through the source-mapping gate before any silver SQL exists. Use when someone asks to map, model, profile, or onboard a new bronze table toward Power BI in the Seshat BI repo -- profile the source, decide grain/PK, fill the five mapping artifacts into mappings/<table/, and stop at the gate. This skill ENFORCES the rule that no silver. SQL is written until the map is reviewed and approved. It profiles and authors and stops; it does NOT write silver/gold SQL and does NOT build the Power BI model.
