Struct LlmSummaryOperatorAttestationEnvelope 

pub struct LlmSummaryOperatorAttestationEnvelope {
    pub schema_version: u16,
    pub purpose: String,
    pub operator_verifying_key_hex: String,
    pub operator_key_id: String,
    pub signed_at: String,
    pub decay_job_id: String,
    pub model_name: String,
    pub prompt_template_blake3: String,
    pub signature_hex: String,
}

On-disk envelope for an operator attestation authorising an LLM summary job. Structurally analogous to the migration-attestation envelope: the Ed25519 signature is computed over a domain-tagged length-prefixed binary encoding of the non-signature fields.

Fields

schema_version: u16

Envelope schema version. Must equal super::DECAY_LLM_SUMMARY_ATTESTATION_SCHEMA_VERSION.

purpose: String

Purpose discriminator. Must equal super::DECAY_LLM_SUMMARY_ATTESTATION_PURPOSE.

operator_verifying_key_hex: String

Hex-encoded Ed25519 verifying key (32 bytes, lowercase, no separator).

operator_key_id: String

Free-form operator key id (matches cortex-identity).

signed_at: String

RFC3339 timestamp the envelope was signed at.

decay_job_id: String

Decay job id this attestation authorises. Binds the envelope to a single job so a captured attestation cannot be replayed against a different job.

model_name: String

Pinned LLM model name (e.g. claude-sonnet-4-7@1). The future backend MUST refuse if the resolved model name differs.

prompt_template_blake3: String

Blake3 digest of the prompt template that will be sent to the LLM. Stored as blake3:<hex> for forward compatibility with other hash families.

signature_hex: String

Hex-encoded Ed25519 signature (64 bytes, lowercase).
