//! S879 Accessibility and localization coverage · Fail-closed evidence reconciliation.
//!
//! Separate typed gate after S878, release track R3,
//! phase R3.5 (Accessibility and localization coverage), step
//! 7/9 of the acceptance ladder.
//!
//! It advances only the fail-closed readiness ledger.  The retained S571/S575
//! physical observations are carried read-only; new runtime and physical
//! observations, operator authority, external acceptance, cross-profile
//! coverage and release-track completion all remain explicitly absent, and the
//! module is deliberately not linked into the board-rpi5 kernel.
