// R-669 (v0.270.0): after a restore writes the app's .felhom.yml, that file IS the pinned version's
// record — so the NEXT update's undo judges the old version with the restored probe, not the failed
// step's. Asserted on what the undo actually reads: savePreUpdateMeta's copy.
//
// COMPANION RED-PROOF (REPORT.md): make RecordRestoredAppliedMeta a no-op (v0.269.1: no restore path
// rewrote applied-meta) → "the next undo would judge with the failed step's probe".
