      "description": "Binds N file digests into one canonical, hash-anchored manifest. manifest_sha256 is SHA-256 over the JCS-canonical sorted entries array. This builds flat manifests with no tree, which is a different job from verify_merkle_batch (cry-04, which verifies Merkle proofs); BrowserChain's log owns Merkle trees. Also serves the plain checksum-tool use case. Returns the manifest plus checks for duplicate names, duplicate digests, malformed hex, and path-like names that are flagged and basenamed. Feeds the conversion receipt builder. Zero network, zero PII.",
