A read-only identity reconciliation report that explains likely matches and keeps ambiguous pairs separate.

Measure: Unresolved duplicate or unmatched lead records (records per fixed reconciliation batch).
Use synthetic or client-authorized deidentified exports with an agency-labeled matching reference.
Acceptance boundary: No automatic merging, ad changes, or causal claims about campaign results.
