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.

Windowed or borderless, DWM composes the window and owns the display's
vsync, so a driver swap interval only adds a stall. On NVIDIA (RTX 4080
SUPER, 610.88) a vsync'd SwapBuffers holds the GPU queue the render
thread submits to: every render-thread frame cost a full refresh
(16.7 ms "GPU" at any internal scale, render_busy 100 %), back-pressure
slowed the guest to 52-57 Hz, and dynamic resolution dropped for
nothing. Measured on R4 0.8 at 7680x4320, windowed and borderless: guest
60.0 Hz, render_busy 5-8 %, GPU 4.4 ms. Exclusive fullscreen keeps
driver vsync; PSX_TRUST_DRIVER_VSYNC=1 restores it everywhere.

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.
Extract the audited adapters and card transport onto master without the held selector/menu stack. Keep adapters and codecs tied to mod activation, use overlay ABI 33, retain rejected-load protection on codec registration, and refuse extended-card codecs in netplay before frame zero. Preserve default atomic save publication and guest-visible write failures.
* feat(widescreen): continue framebuffer-feedback sprites into native-wide bands
Titles tag a 15-bit sprite that copies a framebuffer 1:1 (gpu_ws_tag_feedback_rect / psx_mod_tag_feedback_rect). Where it touches the draw area's edge, gpu.c emits band spans and the new optional backend op wide_feedback_rect (GL incl. render thread, software) samples the source buffer's wide surface. Band texels count as bit 15 set, as the centre does once the trail blends.
The software rasterizer now writes the texel's bit 15 into the framebuffer, and wide_full can dump the surface alpha ("alpha":1).
* fix(widescreen): quantise band feedback like packed VRAM
The centre samples 5-bit packed VRAM each frame; the band copy read the 8-bit wide surface and modulated with /128, so the bands drifted ~3 grey levels brighter and left a step at the 4:3 edge. Truncate like PACK_FS and modulate like TEX_FS.
* Reject fully clipped sprites before extending feedback margins
* Complete isolated resident and PGXP fixture collaborators
* Preserve existing line endings in the review fixes

regen_bios_profile now records generated/<out_stem>.emitter.sha via tools/bios_emitter_fingerprint.cmake, like tools/regen_bios.sh, so the next configure does not report the fresh BIOS as STALE.
