Live Authority Binding (LAB)
LAB binds an action to the authority state at execution time — not at authorization time. The binding is computed by hashing the concatenation of the authority state hash, the execution event hash, the actor identity hash, and a microsecond-precision timestamp. If the policy changed between authorization and execution, the LAB binding reflects the state at execution.
Inference Attestation Wrapper (IAW)
No major LLM API returns attestation evidence during inference. IAW wraps every LLM call with a receipt pair:
Pre-Execution Receipt
Sealed before inference. Contains actor identity, governing policy, constraint envelope, prompt hash. The gate token must exist before inference proceeds.
Post-Execution Receipt
Sealed after inference. Contains inference metrics, response hash, constraint compliance, custody disposition. Cryptographically linked to the pre-auth receipt.
Prompts and responses are never stored — only their hashes enter the chain. The gate is structural: execution is blocked, not logged, until the pre-auth receipt is issued.
