1//! A decision's signed summary (0.96).
2//!
3//! The Lawyer seat writes it; the Steward accepts it, or the other three
4//! seats when the Steward is recused on the item (Steward, 2026-10-17). It
5//! is part of the signed record, so changing it after signing takes a
6//! [revision](crate::govlog::Revision) patching `/summary`.
