//! One Context Gateway Decision Receipt per tool call (G4).
//!
//! After the final result exists, the call's admission decisions become a
//! validated receipt that binds the returned bytes. The receipt is persisted
//! content-addressed, and its security actions are recorded once through the
//! signed audit trail, which is where the status line and `lean-ctx value`
//! take their numbers from. A receipt that fails to persist is never claimed:
//! `lean-ctx inspect` only shows stored receipts.
