Resolve a bank / financial institution across identifier systems. Give exactly one of bic (SWIFT/BIC), lei, or fdic_cert and get the others back: LEI, every ISO 9362 BIC the institution registers, the FDIC institution record (when matched), jurisdiction, and a canonical name. The BIC<->LEI bridge is authoritative and live from GLEIF (the LEI record carries the institution BIC list, CC0); anchoring on an FDIC certificate returns the FDIC BankFind record and best-effort name-matches it to a GLEIF LEI (flagged via bridge). There is no free FDIC-cert<->BIC table, so the FDIC<->GLEIF link is name-match only -- per-source status + bridge make any partial resolve explicit. Sources: GLEIF (CC0) + FDIC BankFind (US public domain).

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
