 - [Phase ?]: [quick-260805-fok]: ensureDefaultGroup-Waechter prueft ausschliesslich group.count === 0, nie die fehlende isDefault-Markierung (D-13); Reparatur laeuft als zweiter sequenzieller await-Schritt in AdminSeedService.onApplicationBootstrap statt als eigener Hook in GroupsModule (Ordering-Falle wie in tender-scheduler.service.ts)
 - [Phase ?]: Checkpoint 1 (16-01 Task 1): approve-both — Group.internalName + ldapObjectGuid + Unique-Index in einer Migration, freigegeben 2026-08-06
 - [Phase ?]: Migrationsverfahren angepasst: prisma migrate dev verweigert nicht-interaktive Shell — Ersatz via migrate diff + Handdatei + migrate deploy, inkl. Baseline der 24 Altmigrationen per migrate resolve --applied
+- [Phase ?]: [16-02]: reassignDefaultBeforeDelete() nutzt bewusst nicht findOwned() — eigenes still-false-Muster fuer Batch-Sync-Laeufe (D-06), kein NotFoundException-Abbruch
+- [Phase ?]: [16-02]: Namenssperre fuer importierte Gruppen (D-03) ist eine Backend-Invariante in GroupsService.update() (BadRequestException), nicht nur ein UI-Disable
+- [Phase ?]: [16-02]: PERM-02 bleibt in REQUIREMENTS.md bewusst auf [ ] — dieser Plan liefert nur den Backend-Teil, das Requirement schliesst erst mit Plan 16-05
