python-pywal was dropped from Arch's [extra] repo (AUR-only now), so
`pacstrap` can no longer resolve it and every ISO build fails with
"target not found: python-pywal". The `wal` binary is load-bearing —
bread-theme shells out to it to extract the colour palette from the
user's wallpaper.
Republish it the same way as calamares / bibata / powerlevel10k /
yay-bin:
- `packaging/python-pywal/PKGBUILD` — in-house copy of the AUR PKGBUILD
(Morten Linderud's), modernised to `python -m build` / `installer`
instead of the removed `setup.py install`, sha256-only sources like
the sibling PKGBUILDs. Test-built locally: 28 unit tests pass, package
ships `/usr/bin/wal`.
- `.forgejo/workflows/python-pywal.yml` — builds + PUTs to the Forgejo
Arch registry on a push to `packaging/python-pywal/**`.
- `signed-repo.yml` gains it as a `workflow_run` trigger;
`ci-publish-signed-repo.sh` gains it in `PACKAGES` so the signed
dl.breadway.dev/arch db picks it up.
- packages.x86_64 keeps the `python-pywal` line (now sourced from
[breadway]) with a note.
Ordering: `python-pywal.yml` must publish to the registry once before
`signed-repo.yml` runs, or the collect step errors "registry db missing
packages: python-pywal".
