Contract-accurate fixtures

EPC rows use MTCH, CMTC, NMTC and NOAP responses, request IDs, millisecond timestamps, BIC agents, and the official payee-verification path.

Negative coverage

Specification truth, not provider folklore.

Fixtures are synthetic and intended for sandbox, staging, CI, and conformance preparation. They do not perform a live account-name verification.
