Identity Correlation Rule Tester
Compare ordered local identity keys and explain unique, ambiguous, shared and unmatched candidates.
Candidate comparison only. A unique local key does not prove identity ownership, account completeness or permission to merge. No automatic merge, tenant lookup or directory write occurs. Reports and disclosed evidence contain original identity data; inspect before sharing.
Per dataset: 2,000,000 characters, 5,000 data records, 100 columns, 16,384 decoded UTF-8 bytes per cell. CSV case, spaces and leading zeros remain literal unless a selected comparison changes them. Email mode lowercases the entire text and removes a leading mailto: after trimming; it is a declared comparison heuristic, not address validation or provider email semantics.
All field pairs in a stage must match. Continue to the next stage only after zero candidates or an incomplete source key. A nonempty candidate group stops the pipeline, including ambiguous or shared targets. Missing/whitespace-only keys never match. Maximum 8 stages and 8 pairs per stage.
Run a valid review to inspect source outcomes.
