turn.undo.test.js: every op with log.undo roundtrips to prior state. startEncounter, nextTurn, togglePause, applyHpChange, toggleCondition, toggleParticipantActive, addParticipant, removeParticipant, endEncounter. Found: reorderParticipants returns log:null. Cannot undo. Documents as BUG-7 candidate (test green now, asserts current behavior).
