src/Core/Cluster/Crypto implements the wire formats of the extension's cluster API v1 (xcvm_core ADR-002), in plain PHP with sodium and OpenSSL: - Enc: the lp()/u64 canonical encoding. - Box: XCVM-BOX-v1 session bodies. - Seal: XCVM-SEAL-v1 to an X25519 key; refuses the all-zero shared secret and binds purpose and context. - PanelSig: verifies panel signatures against the closed tag registry. - NodeSig: the node key's own signatures, under a separate domain string so they can never pass as panel records. - Canonical: the panel-owned request/response serialisation. It is the BOX context and the MAC input, with a ±90 s window and header parsing. - Ticket, RelayAuth, FileDigest: relay and file tickets, the child's per-connect relay proof, and owner-signed file digests. - ClusterCrypto: a facade over XC_VM::cluster_*. Refusals throw ClusterRefusedException with the extension's reason code. - ClusterCryptoFactory: fails closed (ClusterUnavailableException) without the extension, outside API 1–1, or without sodium/AES-GCM. No PHP fallback ships. Tests: - The panel matches the extension's shared vectors byte for byte (tests/Support/cluster_vectors.json, copied from xcvm_core): SEAL, BOX, panel signatures, the licence binding and CK_B, and the whole token chain an agent runs. - tests/Support/cluster_canonical_vectors.json freezes the canonical request/response bytes for the Go agent. - Also added: SignTagSeparationTest, ClusterTicketsTest, ClusterCryptoFailClosedTest (including a check that nothing under Core/Cluster signs as the panel or computes tokens) and ClusterCryptoBenchTest. - Timing: 64 KB is ~0.25 ms p99 against the 1 ms budget; 8 MB is ~41 ms here against a 40 ms target, guarded at 2x. The reference crypto that only xcvm_core or the Go agent computes (binding, token MAC, session keys, panel signing with a seed) lives in tests/Support and never ships.
