PlayActionsHandler + EchoHandler now call RecordCopyTokensFrom (ordered after plain/choice mining) to resolve a copy add's baseIdx against the side's live idx->cardId map and record copyIdx->cardId. A copy played in a later (or same) frame synthesizes a knownList instead of degrading. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
