Struct AttesterKey 

pub struct AttesterKey {
    pub key_id: String,
    pub algorithm: String,
    pub public_key: String,
}

A public key a provider publishes at the handshake, so a verifier can check the attestations it goes on to serve (SPEC.md §6.5.4).

A construction anchor, not a trust anchor. A key handed over by the party being audited says nothing about who signed; it is enough to decide whether an attestation is built the way §6.5 requires, which is the half F6–F9 make mandatory. A deployment that cares who signed resolves key_id in its own trust store and ignores this field.

It rides the handshake rather than the answer for a reason: a key republished with every response could be swapped by the same forgery that swapped the signature, and a wrong-key signature would then verify. Declared once, before any frame moves, it cannot be.

Fields

key_id: String

The key’s id, matching ProvenanceAttestation::key_id. Rotation is a new id, never a reused one.

algorithm: String

The scheme this key is for, e.g. ALGORITHM_ED25519.

public_key: String

The raw public key, lowercase hex — the encoding ProvenanceAttestation::signature already uses.
