//! S625 Signed A-B secure update · Negative and fault matrix registration.
//!
//! Separate typed R2 gate after S624, workstream 7
//! (Signed A-B secure update), step 5/9.
//! It advances only the fail-closed acceptance-readiness ledger.  Supported-profile
//! runtime observations, physical observations, operator authority, external
//! acceptance and R2 field acceptance all remain explicitly absent, and the
//! module is deliberately not linked into the board-rpi5 kernel.
