Stage the next side-project: patch upstream Chromium to do HW video
decode through VaapiVideoDecoder + our marfrit/libva-v4l2-request-fourier
backend on a mainline Linux Wayland system, instead of going through
the chromeos pipeline that fails on Brave today.
STUDY.md captures:
- The exact failure stack we're fixing (PickDecoderOutputFormat ->
ImageProcessor init failure in media/gpu/chromeos/video_decoder_pipeline.cc)
- Three candidate patches (chromeos pipeline bypass, V4L2VideoDecoder
factory un-gate, libva backend default)
- Reference forks (JeffyCN, igel-oss, 7Ji-PKGBUILDs/chromium-mpp,
amazingfate/chromium-debian-build) — all use the older V4L2VDA path
with vendor MPP, not VAAPI; useful for PKGBUILD shape and
factory-un-gating patterns but not directly applicable
- Build plan on fermi (depot_tools, ~30 GB fetch, 6-10 h initial build,
distcc-avahi acceleration through CT108 + tesla)
- Phase order — workspace done now, build env next session,
patches after that, package after that, brave-fourier rebase last
No PKGBUILD added yet; one will land when there's something to actually
package. Build artifacts intentionally not in repo (chromium tree is
~100 GB).

First carrier package for the Fourier umbrella. Tracks Kwiboo's
v4l2-request-n8.1 branch (ffmpeg 8.1 base) pinned at commit b57fbbe —
bump _commit to rebase onto newer tip. CI job chained after
claude-his-any so it serializes on the shared aarch64 repo-db;
continue-on-error: true so long ffmpeg builds don't block the debian
downstream.
Deliberately diverges from the AUR package:
- AUR pins 6.1.1 with epoch=2 → would downgrade stock Arch ffmpeg 2:8.1-3.
We track 8.1 so install is a sideways swap, not a regression.
- AUR pulls X11/AMF/CUDA/FireWire/AviSynth/OpenMPT/Bluray/OpenMAX/JPEG-XL/
Theora/XVid/rsvg/soxr/ssh/vidstab/modplug/SDL2/Vulkan/JACK/GSM/Speex —
dropped here; none are needed on a Wayland ARM video-decode fleet.
- AUR uses #branch=…, sha256sums=(SKIP) → every build is tip-of-branch,
not reproducible. We pin via #commit=<sha>.
Kept: encoders (libx264/libx265/libvpx/libdav1d), VAAPI, libdrm, libv4l2,
neon, OpenGL, PulseAudio, subtitle/font stack, gnutls TLS. SDL2 dropped
means no ffplay binary (mpv covers interactive playback).
provides=(ffmpeg) conflicts=(ffmpeg) so it replaces stock ffmpeg on the
target host deliberately. Primary consumers: ohm (Fourier step 5),
fresnel, ampere.
pkgrel 16 builds ship an upstream distcc 3.4 bug: src/compile.c sizes
the rewritten-compiler-name buffer with strlen(argv[0] + 1) — pointer
arithmetic applied before strlen — under-allocating by 2 bytes. glibc
FORTIFY_SOURCE=2 catches the resulting overflow in strcat and aborts,
so every "distcc gcc ..." invocation dies on a modern Arch.
Patch moves the +1 outside the strlen, as intended.
Closesmarfrit/marfrit-packages#3.

Observed two flakes in 24h — distcc-avahi-aarch64 at 66a7050 and lmcp-any
at 22060e0. Journal for both showed the job starting then failing silently
before any sudo/makepkg line. Theory: transient pacman mirror sync
failures on \"pacman -Syu --needed\" in the bootstrap steps, with the
rsync-to-nc step as secondary exposure (IPv6 prefix rotations from the
Fritz reconnect cron are visible in the runner journal).
Wrap pacman -Syu (5 sites), rsync to nc and hertz (5 sites), and ssh
publish-deb (2 sites) in a tiny 3-try exponential-backoff retry helper
defined per-step. No workflow restructure, no job-graph changes.

distcc-avahi build failure was breaking the entire chain (lmcp-* and
claude-his-* depend transitively on it). These jobs only share a runner,
not real build outputs — one failing package should not block the
others.

Tag v0.1.3 added the scripts + quickref, v0.1.4 fixed doc paths.
Package both /usr/bin/repo-inventory.sh and /usr/bin/repo-inventory-nosudo.sh.

Claude Code Edit semantics — literal string replace with uniqueness
check. replace_all flag for bulk edits. Fixes missing edit tool on
lmcp-backed boltzmann / tesla / broglie.

- arch/claude-his-agent/PKGBUILD: fetches v0.1.0 tarball from
git.reauktion.de/marfrit/claude-his-agent, installs agent+skill+helper
to /usr/share/claude-agents/, /usr/share/claude-skills/his/, /usr/bin/
- debian/claude-his-agent/: control+changelog+copyright + build-deb.sh
mirroring the lmcp-debian pattern (dpkg-deb, reproducible mtimes)
- .gitea/workflows/build.yml: two new serialized jobs (claude-his-any +
claude-his-debian) after lmcp-debian; same publish flow as lmcp.
makepkg output isn't byte-deterministic across runs; same pkgver-pkgrel
rebuilds produce different .pkg.tar.xz bytes. repo-add no-ops on
same-version entries, leaving the db's CSIZE/SHA256 pointing at the
previous build while the nc copy is the new one — alpm then refuses
download with 'Maximum file size exceeded'. Force-remove first.

reprepro refuses to re-include a .deb if the bytes differ from one
already in pool/. Fixed mtimes via SOURCE_DATE_EPOCH make subsequent
builds byte-identical, so CI re-runs of the same pkgver/pkgrel are
accepted as no-ops instead of failing.

- debian/lmcp/build-deb.sh fetches the v0.3.0 tarball, lays out the
filetree, and uses dpkg-deb to assemble lmcp_0.3.0-1_all.deb directly
on the Arch aarch64 runner (no debhelper needed for a pure-Lua pkg).
- workflow job 'lmcp-debian' rsyncs the .deb to hertz's marfritrepo
incoming dir, then ssh-triggers 'publish-deb <suite>' for both
bookworm and trixie. publish-deb wraps 'reprepro includedeb' and
rsyncs dists/+pool/ to nc.
- New secret MARFRIT_REPO_HERTZ_KEY uploaded to Gitea repo. Forced
command on hertz routes rsync uploads vs publish-deb triggers.

lmcp is arch=any (pure Lua). One build on the aarch64 runner serves
all pacman targets — the pure-Lua package drops into both repo dbs.
Depends on lua + lua-socket from the target distro's base repos.

Fixes install conflict with filesystem pkg on merged-usr systems where
/usr/sbin is a symlink to /usr/bin.

- distcc-3.4 tarball hash + local support files hashed (no more SKIP)
- .gitea/workflows/build.yml now builds, signs, repo-adds and rsyncs
to nc via the marfrit-repo-deploy key. Triggers on push to arch/**
or manual workflow_dispatch.
