Description
This PR adds support for tracking and analyzing a critical file related to the Email Verification Protocol (EVP):
/.well-known/email-verificationChanges
parseResponsecall for/.well-known/email-verificationto track its presence and extract key metadata cleanly without overloading the payload, such asissuance_endpointandsigning_alg_values_supported.Example Output
EVP (
