=== LIVE /backups/apps on 0.220.2
  'pre-restore' occurrences on the page : 0
  real app rows (positive control)      : bookstack docmost kimai privatebin 
  undo copies on disk right now         : 6

  The reported symptom did NOT reproduce on v0.219.0 either — it was read on the live page
  BEFORE any change was made. What was real was the phantom map KEY, now fixed.

=== the prune cap in force (max 3 per app):
  docmost    3 undo copies
  bookstack  3 undo copies
