Replace the challenge-less static-SHA-256 daemon bearer credential with a SCRAM-SHA-256-style challenge/response and a salted PBKDF2 verifier store. PROTOCOL_VERSION 2.18.0 -> 2.19.0; legacy user:SHA256HEX stores hard-reject. - credentials: b64/rand/PBKDF2/HMAC primitives, verifier store parser, constant-time proof verify + ServerSignature, --hash-credentials helper - config: auth block is now [present][username]; client runs the challenge exchange; config_burn_auth wipes plaintext/derived secrets (A7-4) - server: gate drives the challenge, dummy verifier for unknown/off-list users - tests: independent Python KAT, replay + legacy integration tests, fuzz paths - docs: new store format, --hash-credentials, 2.19.0 bump TLS verification behavior (A7-3/S1) is intentionally unchanged.
