store/

Package conformance is a shared test suite every gateway.CertStore implementation must pass, so gateway.MemoryCertStore, gateway.FileCertStore and store/redis.Store (and any third-party implementation) are held to the exact same contract.

Package redis provides a Redis- or Valkey-backed gateway.CertStore, so that every process in a deployment shares one persistent certificate store: a node that cold-starts fetches already-issued certificates back from the server instead of depending on the issuer being reachable/willing to re-issue.
