S637 · Doğrulanmış boot ve rollback · Fail-closed kanıt mutabakatı

#![allow(unexpected_cfgs)]
#![allow(dead_code)]

//! S637 Verified boot and anti-rollback · Fail-closed evidence reconciliation.
//!
//! Separate typed R2 gate after S636, workstream 8
//! (Verified boot and anti-rollback), step 8/9.
//! 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.
