How this source contributes to the canonical graph.

Records ingested from Mining Leases Registry are normalized (phone E.164, parish names, business-name cleaning), then put through the blocking and merge pipeline. When a record matches an existing canonical entity above the 0.92 confidence threshold, it is auto-merged and attributed via source_attribution. Below 0.92 and above 0.70 it enters the review queue. The Mining Leases Registry source carries a confidence weight of 0.78 in this scoring.

Every JBIP canonical entity that contains data from this source can be traced back to it via the public profile page (when available) and via the /api/v1/entities/{canonical_id} endpoint.
