setLineageForAdministration
public ClassProgressionSetResult setLineageForAdministration(UUID playerId, String formId, int effectiveLevel)
Permission-gated tester fixture: completes every ancestor band, sets the requested form to an exact visible level, and selects it. Foundation requirements remain authoritative.
This is deliberately a domain operation instead of direct command-side persistence so testers cannot create an impossible branch state. It is rejected while a dungeon run owns the player's selection.
