Keep selector zero stock and seal all choices until the next session restart. Refuse nonzero online activation, scope non-stock save states by frozen choices, and preserve original instruction guards when combined with effective-address adapters. Use overlay ABI34 on current master without the old menu dependency stack.
psxrecomp owns the contract between the runtime and any in-game menu
frontend. A provider (PsxMenuProvider: attach, event, is_open, set_open,
draw, detach) is registered by the title with psx_menu_set_provider();
none is registered by default, so a title's UI and pin are unchanged.
The runtime offers every provider the same host (PsxMenuHost): pause
(P1, refused in netplay), video get/apply on PsxHostVideoSettings (P4),
mod switch/option set (P5, via the new psx_mod_feature_enable /
psx_mod_feature_set_option shared with the launcher ABI provider),
reload bindings, exit (quit, back to the frontend loop in-process, or a
quick relaunch with the original arguments), disc/tray slots filled by
the tray policy (psx_menu_set_disc_ops), and optional helpers on the
shared launcher ABI both frontends already speak (game info with the
mod catalogue and lobby, settings get/apply with the handoff's filter
translations).
Policies live here, the same for every provider: the lobby is pumped
during play and a started match ends the local session and starts in
the frontend loop (pending launch, seats and signals kept, pumping
stopped so the match port stays free), the menu is closed and its pause
dropped first; the provider detaches before its GL context goes away at
session teardown and attaches to the next one. --launcher sets
RECOMP_LAUNCHER_PREGAME for frontends that boot into the game;
PSX_HIDDEN_WINDOW is a hidden-window test hook that keeps the frontend.
Nothing here includes or names a frontend's own headers or types.
Tests: psx_menu_host_test, host_overlay_test (relaunch quoting).

psx_host_pause_push/pop: a nesting, host-owned pause. While it is held the
runtime freezes the guest at the vblank present (as the save-state menu
does), keeps presenting the last frame and pauses audio. Push refuses
during netplay. Nothing pushes unless an overlay provider (or the debug
server's new host_pause command) asks, so behaviour is unchanged.

A title may declare [quality.low|medium|high|ultra] tables of [video] keys.
On first launch, and when the hardware fingerprint changes while a preset is
in force, psxrecomp detects the CPU, threads, RAM and GPU (OS facts; a hidden
1x1 GL window reads GL_RENDERER only when a detection is due and the OS did
not name the GPU), picks the matching preset and saves quality_preset,
quality_base, quality_hardware and quality_detected to settings.toml.
- Each preset is the whole game.toml re-parsed with its keys over [video], so
every [video] key works in a preset with its usual validation.
- A preset in force owns its keys: saved settings.toml values for them are
ignored. Custom (the player changed a governed setting in the launcher)
applies the player's values over quality_base and is never overridden;
new hardware under Custom is only reported.
- Launcher: GameInfo.quality_* (offered mask, detected preset, hardware
summary, quality_apply / quality_redetect callbacks) and
Settings.quality_preset/quality_base, behind RECOMP_LAUNCHER_HAS_QUALITY_PRESETS.
- PSX_QUALITY=<preset> for one run, PSX_QUALITY_REDETECT=1.
- Titles without [quality.*] are unchanged.
Rules (quality_tier.c) and the decision are unit-tested in
quality_presets_test; docs/QUALITY_PRESETS.md.

Detected from a gamescope session (XDG_CURRENT_DESKTOP, GAMESCOPE_WAYLAND_DISPLAY)
or Steam's gamepad UI (SteamGamepadUI=1); --game-mode / --no-game-mode and
PSX_GAME_MODE override. When on and a disc is set up, the launcher is
skipped and the game opens borderless fullscreen for that run (the saved
Fullscreen choice is untouched); the first run still shows the launcher so
the disc can be picked. Desktop sessions, --headless and --hidden-window are
unchanged. game_mode_test covers detection and precedence; docs/GAME_MODE.md.

The seed path collapsed ls.texture_filter to a boolean, so a launcher's
xBR (3) was saved and applied as bilinear, and the rematch paths passed
the raw value through unchecked. psx_texture_filter_from_ui is now the
one translation (in-range values pass, others are nearest). Test:
video_texture_filter_test.

Review (mstan): the title key is now experimental_jogcon_force_feedback(
_invert) and the runtime logs it as EXPERIMENTAL. Force feedback goes through
a pure driver (psx_jogcon_ffb.h) and an SDL haptic backend
(psx_jogcon_ffb_sdl.cpp): every force has a 120 ms lifetime renewed each
VBlank, so a pause, stall or crash goes slack by itself, and the Rewind and
save-state pause loops, disconnect (close_player) and session end
(close_controller) stop it explicitly. Tests: jogcon_ffb_test drives the
driver against a recording backend (lifetime, renew, stop once, neutral,
idempotence, disable mid-force); jogcon_ffb_sdl_test runs the SDL backend
against an SDL3 virtual wheel. SDL has no virtual haptic device, so it checks
that such a device is not driven, never falls back to rumble and closes
cleanly. Also fixes the SDL3 haptic subsystem init check (psx_sdl.h returns
0 on success).

Clang on arm64 contracts a*b+c into an FMA by default; x86-64 GCC without
-mfma never does. The software rasterizer's float edge/shading math then
rounded differently on a Mac and a Windows peer: +-1 colour steps on single
pixels, so VRAM (the av digest) diverged from ~sim 1800 in every
cross-machine R4 rollback race while the core digest still matched. Each
rollback baseline compare then aborted on "baseline av mismatch", and the
realigns forked the session (3P never reached the race; 4P diverged
mid-race).
VRAM dumps from the same Mac-host 2P race at 16 ticks between sim 1600
and 2080: 1-3 differing pixels in 5 of 16 frames before, 0 after.

The X4 co-op contract already fingerprints SPU and private audio sources. Defer the additional global execution-contract inputs, added after the approved Windows build, until a coordinated rebuild of both platforms. This preserves the owner-tested Windows artifact for playtest 2.
Opt-in under the render thread. Composed frames go to a ring of offscreen
slots at the window's size (binds of framebuffer 0 on the composing context
land on the current slot); a present thread with a second, shared context on
the same window waits on the slot's fence, copies it 1:1 and swaps. The
compositor's wait moves off rendering; the composing side waits only while
every slot is queued or on screen. Falls back to direct swaps when the shared
context or sync objects are unavailable.

[video] frame_generation (opt-in, with render_thread): the render thread keeps
each game frame's replayed draw list, matches the triangles of the last two
(frame_gen.c), and presents in-between frames at the display refresh by
redrawing the newer list into separate surfaces with matched vertices
interpolated. It never runs guest code. Real frames are composed at their
flip and presented after the generated ones, with the same pixels and
order. Generation uses only measured surplus: a plan from render-thread CPU,
generated-frame cost and swap time, a breaker after backpressure or late
guest frames, and a pause while dynamic resolution is over budget. The
render-thread core gains a timed tick hook. Frame-cost queries pause around
generation, so dynamic resolution measures real frames only.
Tests: frame_gen_test, render_thread_test (tick), gl_frame_gen_test (real
frames identical off/on; phase 0/1 equal the endpoints). Docs:
docs/FRAME_GENERATION.md.

Backend-neutral core for the opt-in [video] render_thread: the emulation
thread appends records to a single-producer/single-consumer ring and the
render thread replays them in order with the graphics context current.
rt_frame_end bounds closed frames in flight (backpressure), the render
thread can tell a frame is stale, and rt_acquire is the sync point:
drain, then move the context to the emulation thread until rt_release.
No lock is held while a record executes.
render_thread_test drives it with a fake executor and context token:
ordering and payload integrity across ring wraps, oversize refusal, the
in-flight bound under a slow consumer, stale detection, randomized
acquire/release interleaving and stop while held (TSan clean).

A step controller (dynamic_resolution.c) lowers or raises the GL internal scale from frame-time telemetry between a floor and the configured ceiling; off unless a title or the player enables it. Tested by dynamic_resolution_test (synthetic load) and the real-GL gl_scale_invariance_test step modes.
