//! S804 Accessibility and localization · Fail-closed evidence reconciliation.
//!
//! Separate typed gate after S803, release track R2->R3,
//! phase T4 (Accessibility and localization), step
//! 7/13 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.
