-ProtocolLib binds taking to the displayed menu generation before payment.

Native aggregate and packet-specific limits remain authoritative, using the actual connection's counters and violation actions; expired/refused/cancelled dispatches never pay. Transport ownership is bounded to 32 records per connection. A queued ProtocolLib-owned main callback followed by a barrier on the same native channel event loop proves whether each exact raw was forwarded; mutable packet/post-event snapshots do not. This library-owned cleanup survives this plugin's task cancellation. Revoked native wrappers retain their denial even when native admission or queue processing skips their handler, while genuinely unresolved late raws keep protective ownership until arrival, the ordered fence or disconnect. Missing/rejected library scheduling or event-loop execution fails closed; it does not establish successful cleanup. Input or acknowledged risk changes invalidate old clicks even when the result item is identical; the ordinary anvil stays open without another confirmation. The adapter is pinned to Purpur 26.2 build 2618 and fails closed when enhanced generation admission is unavailable. This is a library dependency, not a Fantasy Stick/gameplay-plugin bridge.

 Use left/right pickup, shift-click or a native-eligible empty hotbar/offhand destination. Full destinations, cancelled/stale takes and unsupported cloning/drop/collection actions do not roll or spend items. Ordinary anvil wear remains in effect. Dedicated gameplay-plugin compatibility is unsupported; declared native cancellations and unrelated inventory state are preserved.
