Contact resolver
A contact resolver consolidates candidate contact observations and selects the strongest available value per channel using identity confidence, verification state, freshness, corroboration, provider provenance, and prior outcomes.

Why it matters in recruiting and sourcing
Recruiters do not need ten emails. They need the best current work email, the best appropriate personal email, the best phone, and the canonical profile link—with confidence and alternatives when the evidence conflicts. Resolution turns enrichment volume into decision support.
Example
Three providers return two work emails and four phone numbers. The resolver suppresses a bounced email, ranks a recently verified work address first, shows one mobile as primary, and collapses stale or lower-confidence values under alternatives.
Common failure modes
- Choosing the first provider response
- Calling every returned value verified
- Ignoring identity confidence
- Ignoring bounce or wrong-person history
- Dumping every observation into the primary profile
