Coherent projection publication and bounded diagnostics; repaired final-pass history advancement and reload clock. Real GL182 checks and combined title regression/visual gate passed. Owner explicitly authorized this merge.
Rebased onto #174, regenerated OpenBIOS fingerprint with the exact emitter and repaired isolated optional-hook fixture linkage; five focused checks pass. Owner explicitly authorized this merge after the combined title regression/visual gate.
Some PlayStation 1 titles implement trivial rejection by folding the sign bits of projected vertex screen coordinates across triangle or quad primitives with a chain of AND instructions. Without adjusting these checks during widescreen presentation, geometry in the newly revealed horizontal area is still rejected by the original 4:3 bounds. Rather than embedding title specific instruction patterns directly into the recompiler, this introduces a generalized `[[widescreen.cull.sxy]]` configuration schema within `game.toml`.
Game configurations can now declare multi vertex trivial rejection sequences by their exact AND instruction words, vertex registers and the branch that consumes the result. The loader derives the expected chain from those words and rejects any other shape. Each AND keeps its original value except for the horizontal sign bit, which survives only while that vertex lies beyond the revealed left edge, so vertical and right side rejection are preserved and 4:3 output is bit identical. Shifted coordinate lower edge comparisons reuse the existing `screen_x_sites` handling through a new `slti rt, x, 0` form instead of adding a separate site family.
Full parity is maintained between recompiled code and the dirty RAM interpreter by sharing the same runtime helper and validating every fold and consumer instruction word on both paths, leaving mismatching overlay variants untouched. This eliminates hardcoded game logic from the recompiler while giving titles clean geometry retention in expanded aspect ratios.
Reviewed repaired head d486a78acf0fcccbedbae9479551abd28a9802cf; combined regression evidence and owner visual acceptance recorded on review/psx-prs-20261024. Owner explicitly authorized merging the six reviewed ready PRs.
For title-specific lighting presets ([video] post_shader):
- `input <sampler> depth`: view depth sz (GTE screen z) of the presented frame,
R32F at window size, rebuilt from the surfaces' PGXP depth; 0 where nothing
3D drew. Only built while a loaded chain reads it.
- `input <sampler> history`: the pass's own target from the last real frame
(trails, temporal filters); generated frames do not update it.
- `u_time` (seconds since the chain loaded) and `u_proj` (latest GTE
projection: 240/H, screen centre in uv, aspect) in every pass.
- Live uniforms: psx_host_set_post_uniform(name, x, y, z, w) sets a preset
`uniform` from game state (e.g. a light source projected to the screen);
the preset value applies until the first call.
- Debug: TCP {"cmd":"post_shader"} reports the loaded preset, its parse status
and the live values; {"cmd":"post_shader","path":"..."} reloads a preset
(or loads another) without restarting, for shader work.
docs/POST_EFFECTS.md documents the inputs and the uniforms.
Used by a lighting preset for R4 (sun and tunnel light shafts, lamp halos,
speed streaks, paint reflections on the player's car from live car pose),
about 0.7 ms of GPU at 1080p on an RTX 3060.

Use a bounded atomic snapshot and presenter-owned reset across all backends. Readers sort their own snapshots; report host API completion cadence. Add deterministic and concurrent reader/reset coverage.
The GL swap records the interval between real swaps (ring of 4096, single
writer). TCP {"cmd":"perf","window_ms":N,"reset":0|1} returns count, fps,
mean / p50 / p95 / p99 / max interval and hitches (intervals over 1.5x the
median) for the last N ms; independent of guest vblank counting, so frame
generation, pacing and driver stalls are all visible. PSX_FPS_TELEMETRY adds
the same summary to the window title.
Used to measure R4 runs on a test bench (60.0 fps, p99 18 ms after the
cadence fix of the video-standard switch).

Live resolution (#737) routes mh_restart_bits through main.cpp's
backend-aware video_restart_bits; the fixture extracts mh_restart_bits
alone, so it no longer compiled. Map it to the fixture's
psx_host_video_restart_bits (no live resolution here).

Keep the requested internal resolution / supersample (shown and saved)
apart from what the backend last applied. When the live change is
unavailable (no GL, windowed high-resolution mode, CPU-authoritative dual
rendering, no context) or refused, the session scale is left as applied and
PSX_VIDEO_RESTART_RESOLUTION stays set, in both psx_video_apply_live and
the menu's restart bits (psx_host_video_restart_bits_backend, unit-tested
for the capable and refused cases). video_set rejects invalid presets and
factors without applying or saving, and reports applied values, capability
and pending restart. TCP command index regenerated.

Narrow host_driver_vsync_unreliable() on Windows to the configuration the
stall was measured on: GL active, render thread running, GL_VENDOR NVIDIA,
not exclusive fullscreen. Other driver families and the unthreaded path
keep driver vsync; PSX_TRUST_DRIVER_VSYNC=1 still forces it everywhere.
Evaluated per call, so runtime renderer/fullscreen changes apply.
