Checks 1–7

EVIDIQ Vault is the governed memory and audit trail for autonomous agents. Record actions in append-only namespaces with SHA-256 hash chaining, seal Merkle segments to 0G Storage, enforce retention by redacting payloads without breaking verification, and prove exactly what an agent did and that nothing was edited afterwards.
