A [[plugin]] may declare netplay = "local_view": it only changes what one
player sees. A netplay session now keeps the player's own features whose every
contribution is such a plugin (no writes, overlays or derived discs) instead of
clearing them, without saving state.toml. They activate as usual, but their
hooks run only inside psx_mod_render_local_view (psx_mod_local_view_scope) and
their vblank/savestate callbacks not at all. With such a plan the widescreen
cull margin is the stock 0 in the shared game and this peer's own margin only
inside the sandboxed own-view draw; squash is not used. The canonical frame,
snapshots and digests stay identical on every peer whatever each player chose,
so nothing is negotiated, and each keeps their own aspect.
Tests: netplay_view_mods_test (flag, plan filter, parked hooks, no vblank,
state.toml untouched), ws_local_view_margin_test (margin scope), render-pass
sandbox asserts the scope around a local view.

psx_mod_render_local_view() runs a title's draw code in the render-pass
sandbox on a forward netplay frame and keeps the drawn display rect in the
OpenGL presenter's surface only. The authoritative CPU VRAM, guest RAM,
rollback snapshots and digests keep the canonical frame; the presenter shows
this peer's own image. A committed image cancels any local-view crop.

A title whose netplay mode draws every seat's view into one frame (so all
peers keep identical guest state) can now ask the present path to show only
this peer's rectangle of the display: psx_netplay_present_local_view(x, y,
w, h), usually picked from psx_netplay_local_slot(). The GL dual-raster
present shows it from the internal-resolution surface, the software present
crops its staged frame, both at 4:3, and the headless present-image ring
records the same rectangle. The request is host-only (never serialized or
guest-visible), lapses PSX_NETPLAY_LOCAL_VIEW_HOLD ticks after its last
renewal so menus fall back to the full frame, survives rollback replays
without moving its stamp backwards, and is ignored offline. It wins over
[netplay] local_viewport.

A digital presentation folds the sticks onto the D-pad and centres them,
so a transform on a digital player (the default for many titles) never
saw the stick. The transform decides what the guest sees, so for a
digital stage-1 pad with no controller source its frame is now the host
pad: real sticks and buttons without the stick->D-pad fold, type still
DIGITAL (new PadExtHooks.host_pad, capture_pad_slot_view). The output is
pre-filled with the stock pad and a decline delivers it, so pass-through
stays the stock folded digital bytes (mod_pad_transform_run takes the
stock pad). Analog pads, sources and guarded frames are unchanged.
Tests: pad_external_input_test (digital player: frame has the real lx and
unfolded buttons, decline and pass-through deliver the stock digital
bytes, no host-pad query for analog / guarded / source ports),
mod_pad_transform_test (decline returns the stock pad, output pre-filled
from it).

psx_mod_set_pad_transform(player, &PSXModPadTransform) registers stage 2b
of pad_external_input: after the physical pad and any controller source,
before the mouse policy. The transform sees the resolved pad plus the
port's host extras (gamepad present, LT/RT 0..255 from SDL, unthresholded)
and may rewrite buttons, sticks and the presented controller type, e.g. a
NeGcon whose I/II come from the triggers. Output is pre-filled as a
pass-through, validated (struct size, ranges, type within allowed_types)
and replaced by neutral when invalid; detaching or a mod/session reset
owes one neutral release frame. initial_type sets the boot/hotplug type.
The resolver stays pure: host extras arrive through a new capture hook and
the transform through another, both covered in pad_external_input_test.
Under the input guard the transform runs on zero triggers and its output
is neutralized. A NeGcon result resets the mouse policy rather than letting
it overwrite the I/II bytes. Offline only: netplay, resim, selfcheck replay
and plain debug overrides never reach it.
With no transform registered every pad is bit-identical to before.

PsxNetPad type 3 is NeGcon, packed lx = twist, rx = I, ry = II, ly = L
(the rollback row's stick view carries twist and L). Every decoder accepts
up to PSX_NETPAD_TYPE_MAX instead of clamping at JogCon, and normalization
keeps NeGcon pressures exact (only twist gets the centre deadzone).
psx_pad_apply_to_sio() is now the one PsxNetPad -> SIO path for offline
sampling, netplay delay/rollback apply and selfcheck replay, so a type
added once reaches the guest the same way everywhere. Selfcheck replay now
matches offline sampling on multitap seats with the analog-on-tap hack.
psx_netplay_normalize_pad moves to a pure TU so tests link the real one
instead of a mirror. Pins recomp-net to the branch that keeps type 3.
Other titles: pads never carry type 3, so SIO bytes are unchanged.

SIO_PAD_NEGCON = 3 presents a Namco NeGcon (NPC-101): poll ID 0x23 with
buttons, twist (left X), then analog I, II and L (Mednafen negcon.cpp).
sio_set_pad_negcon() supplies I/II/L per frame like the sticks. The device
has no config mode: any command but 0x42 gets the ID byte with no ACK, and
game bytes in a poll drive no motors. Multitap seats stay digital unless the
analog-on-tap hack is armed; the bulk status block carries the NeGcon frame.
Entering or leaving NeGcon is a device swap, not the DualShock analog
button: a deferred request applies even while the game holds the 0x44 mode
lock, and the swap clears the lock, config latch and motor map. Requests
raised mid-config still wait for config exit.
0x44 now selects the analog mode of the device in the port: a JogCon the
game set to digital returns as a JogCon instead of becoming a DualShock.
The mode lock and that device are guest state, so they join the snapshot
as an appended section (older snapshots still load, unlocked).
pad_status reports negcon and mode_locked per slot.

- 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.

Trusted game code can register entry hooks and consuming filters that run
only in a netplay session (psx_game_register_netplay_function_entry /
_filter). They live outside the mod package plan, which every online
match clears, so a title's netplay support survives it. Offline they are
inert unless PSX_GAME_FILTER_OFFLINE_PROBE=1. Reimplemented on master's
entry-filter path from the R4 Link Battle branch.

Mouse policy now folds onto the resolved pad (source included) instead of a discarded capture; no-policy path does no mouse polling.

Loss no longer returns 0 forever; EXITING tears down and stays disabled. begin() syncs actions so hands work without polling input. Timeout code no longer treated as writable.

Pair is fresh only within 24 vblanks of its capture cycle; savestate/session reset already invalidate it.
