- psx_netplay_seat_count() and psx_netplay_sim_pad(seat, out): the pad row
last published to SIO for each seat at the current simulation tick,
following delay-sync publication and rollback's sealed overrides, for a
game hook whose title reads more players than its SIO protocol exposes
(R4 Link Battle). Host-only cache, never serialized; republished on
every admitted or replayed tick.
- Load barrier: while a slower peer is still applying a save, neither
mode waits for confirmation from an already-frozen peer (rollback did
this already); after mutual ready, both modes resume on a confirmed
first tick instead of rollback inventing it, so peers cannot run
different inputs from the identical restored state.
From the R4 Link Battle branch; its headless input probe is dropped
because master already honours debug input on headless peers.
