- ca/issue.ts: real X.509 v3 Ed25519 leaf with SPIFFE URI SAN, signed by the intermediate; SAN built via relay-auth spiffeIdFor so it can't drift - ca/csr.ts: parse real PKCS#10 (agent's PEM) + async PoP verify; decodeCsrWire accepts PEM or base64(DER) - main.ts/env.ts: real issuer when CA_INTERMEDIATE_KEY_PATH present, else dev fallback - interop.test.ts: oracle proving relay-auth verifyAgentCert accepts the leaf (6 tests) - deps: @peculiar/x509, reflect-metadata
