chromium-fourier r2 + firefox-fourier 150.0.1 + KWIN_PIVOT.md
chromium-fourier:
- patch 3/3 nv12-external-oes-on-modifier-external-only.patch — adds
  NativePixmapEGLBinding::ModifierRequiresExternalOES helper, extends
  OzoneImageGLTexturesHolder::GetBinding to honor EGL external_only
  flag for NV12 dmabufs on panfrost / panthor. Validated on ohm
  (RK3566 hantro mainline 6.19.10): bbb_1080p30_h264.mp4 plays at
  34.7 % combined CPU vs ~131 % pre-patch baseline (~3.8x).
- PKGBUILD pkgrel 1->2, source array + sha256sums + prepare() hook for
  patch 4, patch numbering 1/2,2/2 -> 1/3,2/3,3/3.
- NEXT.md appended with 2026-04-28 section: patch 4 design, validation
  log, KWin GL_ALPHA bug pinpoint (preexisting since 2026-03-06,
  affects every wayland video client; unrelated to chromium-fourier),
  device-renumbering note (/dev/video1 = encoder post-reboot).
- KWIN_PIVOT.md: 4-phase plan to identify and patch KWin's
  glTexImage2D(internalFormat=GL_ALPHA) site, ohm-only test plan,
  scope discipline.
- patches/ now tracked (compiler-rt-adjust-paths, enable-v4l2,
  wayland-allow-direct-egl-gles2, nv12-external-oes); the dead-end
  chromeos-pipeline-bypass.patch removed.

firefox-fourier:
- 4 patches (gfxinfo v4l2 stateless fourccs, libwrapper hwdevice ctx,
  ffmpegvideo v4l2-request route, prefs v4l2-request default).
- PKGBUILD bumped to firefox 150.0.1, Arch toolchain glue patches
  layered in, mozconfig with --without-wasm-sandboxed-libraries for
  ALARM, package() launcher fix (rm -f symlink before cat > to avoid
  ENOENT through the dangling /usr/local symlink mach install drops).
- 150.0.1-1-aarch64.pkg.tar.zst built on boltzmann (95 MB), pending
  fresnel power-on for V4L2 stateless validation on RK3399.

# Arch's 0004 patch updates the wasm32-wasip1 target string but ALARM's
