1. .work/R4.11/lib.ps1:28 — [P2] The acceptance driver's backup does not preserve an originally absent configuration file. All five scripts reuse run/kept; Keep-Data overwrites existing files but leaves old snapshots when a source file is missing, and Restore-Data restores those snapshots unconditionally. Run the driver once with settings.json present, delete that file to reset the settings, then run it again: the second run restores the first run's obsolete settings instead of leaving the file absent. The same applies to session, recent-file and view state. Reproduced using the unchanged backup/restore functions with disposable directories; evidence: .work/R4.11-r1/backup-probe.log. Use a fresh backup directory for each run, or record each file's original presence and clear stale snapshots for absent files; add a two-run regression that verifies both bytes and absence are restored.
