Duels record the rules revision they began under

CURRENT_RULES is stamped on the start line and the game state, and a
ledger replays under the revision it recorded (1 when it has none), so a
future fix that changes how a past turn resolves can keep the old path
for old duels. The reports desk skill now says when to bump it: only
when the deploy gate flags ledgers.
