Struct BodyRef 

pub struct BodyRef {
    pub reference: String,
    pub size_bytes: u64,
    pub sha256: Vec<u8>,
    pub encryption: Option<u8>,
}

The claim-check capsule a agdx.ct = ref body carries.

The content lives elsewhere (object storage, the KV store, another topic). The record carries where it lives, how big it is, and a digest, so any consumer verifies the fetched bytes against the log without trusting the store. The envelope and the validity matrix are untouched: a referenced body is still a body, just one whose bytes are a BodyRef instead of the content itself.

Fields

reference: String

Where the bytes live: a URI, object key, or KV key. Bounded by MAX_BODY_REFERENCE_BYTES.

size_bytes: u64

The externalized content’s size in bytes.

sha256: Vec<u8>

SHA-256 of the externalized content, exactly 32 bytes as a CBOR byte string.

encryption: Option<u8>

Encryption scheme code, dormant like Signature::scheme. Absent means plaintext. Codes are assigned when the key registry (the same registry signatures verify against) lands.

Implementations

impl BodyRef

pub fn new( reference: impl Into<String>, size_bytes: u64, sha256: [u8; 32], ) -> Self

A plaintext reference to externalized content.

pub fn validate(&self) -> Result<(), ValidateError>

Check a decoded capsule: non-empty bounded reference, 32-byte digest.

Receivers run it after decode. new is valid by construction.
