Expose the insecure MsQuic draft API and add an opt-in setting on both
peers. Query the negotiated state after connection establishment so
one-sided opt-in remains encrypted and is logged accurately.
Isolate input sends from shared transport accounting and reserve
reliable capacity.
Prioritize QUIC execution and bound stale motion through the Windows
pipe and HID queues.
Route input through a dedicated high-priority stream, send pointer
motion as cumulative datagrams, and recover suspected loss reliably.
Reduce downstream input queuing with age-aware coalescing and input
thread scheduling.
