The OpenGL renderer has always drawn shaded and texture-modulated pixels
at 8 bits per channel with no dither pattern (true colour). That stays the
default. 'on' applies the PS1 4x4 offset matrix and 5-bit truncation per
internal-resolution pixel; 'scaled' puts the pattern on the native grid,
so it reads like the console at any scale and the native VRAM is the same
at every internal resolution.
GP0(E1h) bit 9 reaches the backend through a new optional facade hook
(gr_set_dither) recorded for the render thread and Smooth motion redraws.
With the mode off nothing flushes and no uniform changes. Flat, raw and
other 5-bit-exact pixels are never touched.

savestate save/load with slot >= SAVESTATE_SLOTS (12) was refused with the
generic message that blames LLE runs, which sent a test chasing the wrong
cause. It now replies "slot N out of range (0..11)". Guarded in
test_savestate_status_protocol.py.

SIGPROF can land on a thread that is still being created. On macOS arm64
pthread_self() there hits a pointer-authentication trap (EXC_BREAKPOINT in
on_prof), which killed debug-tools builds at boot when a second instance
started lobby threads. The handler now compares the interrupted stack
pointer with the emulation thread's stack range; Linux keeps pthread_equal.

PSX_EXECUTION_ID hashed raw bytes of the contract files and generated
bodies. A Windows checkout with core.autocrlf=true (the Git for Windows
default) has CRLF in every text file, so a Mac and a PC build of the same
commits (R4 #35, psxrecomp 2a4824fc) got different identities and the
netplay content gate refused the session with "content mismatch". LF
files hash exactly as before.

gpu_ws_background_requires_full_composite and gpu_timeline_note were defined
twice after a merge, so every GL fixture that includes this file
(gl_post_aa, gl_bloom, ...) failed to compile.

The default demanded SCPH1001.emitter.sha, which is gitignored (retail output
is generated from a dump, never committed), so every game's release CI failed
with 'SCPH1001.emitter.sha missing' on a clean checkout. Default to every
generated/*.emitter.sha; naming a stem still requires it.

The lobby server starts a 2-player room the host relay cannot carry on ICE
(recomp-net-server start_transport, launch transport "ice"). This client
knew only "host" and the legacy server relay. It inferred a relay from
equal host/guest endpoints -- which is exactly what two peers behind one NAT
advertise -- and each peer dialled its own public address: the match stayed
at "linking" forever.
- psx_lobby_launch_transport.h: one pure decision (host / ice / relay /
direct) with a unit test covering ICE, same-NAT endpoints, host relay and
the legacy relay cases.
- PsxLobbyJoinInfo.transport_ice; the launch handler records it and never
turns it into a relay; launch fill and resolve_use_ice start ICE p2p
(signalled over the lobby) for it.

Keep both netplay_peer_frontier.h and netplay_fmv_confirm.h includes; advance lib/recomp-net to a48d355 (main, includes #38).

- The dirty-RAM interpreter's IRQ poll stride is host-only; a load resets
it to phase 0 while Live carried an arbitrary phase, so a replay could
take the VBlank in RAM code at another instruction. It is now
re-anchored at every tick boundary in Live and Replay alike.
- The av digest zeroes the three depth-24 present helpers at the end of
the GPU snapshot (upload span, present hold, previous height): host
presentation state a suppressed-present replay leaves different, not
guest-visible.

PSX_RB_DET_SELFTEST on R4 4P showed a replayed save of tick T differing
from the live save of T. Each cause, and the fix:
- Replay's finish_frame poll passed no PC hint (Live used the IRQ resume
chain); it now uses psx_netplay_snap_resume_hint.
- Devices are serviced lazily up to the next event, so root counters and
cycles_since_vblank lagged the clock by a host-path amount at save; a
load re-anchors them at the clock and drops the lag. The save now
publishes pending cycle charges and services every device to the clock
first, and renders the SPU up to it.
- GTE / mul-div completion stamps and the load-delay give-back were
re-anchored at the restored clock on every load, so a stall in flight at
the snap point cost the live run cycles but the replay none. New
BS_SEC_CPUTIM carries them relative to the clock.
- The SPU CD-input FIFO was outside the snap and wiped on rollback loads;
new BS_SEC_SPUCD carries the queued frames and the load keeps them.
- LZCR is serialized as derived from LZCS (the raw backing stays 0 until
the first LZCS write; guests only ever read the derived value).
Older snaps without the new sections load as before.

Replay's finish_frame saved its tick snap with no PC hint while Live used
the IRQ resume / last check / cpu->pc chain; the same tick's snap could
carry a different resume PC (psx_netplay_snap_resume_hint now serves both).
