//! The `data` of a `council_decision` entry (`GOV-YYYY-NNNN`).
//!
//! Read-side types for the verbatim record. Keep the raw `data` alongside:
//! `data_hash` covers it as stored, not as these types re-serialize it. See
//! [`GovernanceEntryResponse::council_decision`].
//!
//! Records have grown fields over time; each later field is optional here
//! and says when it appeared, so every entry ever signed still parses.
//! Free text is [`Redactable`]; a redaction of anything else (a vote, a
//! whole round) does not parse.
