Functions

check_commitment_authority

Check whether the sender is authorized to commit per the policy’s commitment.authority rule.

decode_commitment_payload

decode_mode_state

encode_mode_state

Shared mode-state JSON codec (extracted from six per-mode copies). Encoding a mode-state struct cannot fail; if it ever does, panic loudly rather than silently persisting an empty state.

enforce_commitment_policy

Shared commitment policy gate (extracted from five per-mode copies). Fail closed: only an explicit Allow proceeds — PolicyDecision is #[non_exhaustive], and any unknown decision denies.
