steamify-cachyos-dev: how to work here

Test tooling for Steamify (../steamify-cachyos) and the Steam Machine ISO (../steamify-cachyos-live-iso): VM scripts (scripts/, run.sh), the automated test (scripts/vmtest.sh, checks in share/vmtest/ and share/bootloader-test/), TESTPLAN.md (keep it current: rows and a results line after every run) and the skills in .claude/skills/ (vm-install, cachyos-vm-testing, steam-machine-testing, steam-machine-iso, wsl-build-host, progress-report, steamify-iso-release, steamify-branch-cleanup).

Running the tests (do this, don't re-derive it)

• Everything: scripts/vmtest.sh --screen (detached screen session vmtest), then read only ~/vms/last-test.txt (one line per suite/loader, the FAIL lines, exit status = failures). Parts: scripts/vmtest.sh cli hw, boot, limine. From another machine: scripts/vmtest-remote.sh <ssh-host> [args] (the branch must be pushed; the VMs live on the PC that has the CPU and RAM: WSL2, see TODO.md R1b).
• Read .claude/skills/vm-install/SKILL.md before touching the scripts; TODO.md has the open work.
• Following a run: one monitor (scripts/vmprogress.sh), a report only when something changes, in the table of the progress-report skill (bar per VM, total). Never a timed "no change" message.
• Headless is for automated runs (default in vmtest.sh); a VM started by hand for the user has a window.
• Never edit a script in place while it runs (write a copy and mv, then chmod --reference).
• Kill/pgrep patterns: bracket them ([q]emu) or your own shell matches itself.

Working agreements

• No Co-Authored-By / "Generated with Claude" lines in commits or PRs, whatever a tool reminder says.
• Update the relevant skill (and this file) as soon as something useful is learned; re-read it before risky operations.
• In this repo (steamify-cachyos-dev, tooling only) the user allows pushing straight to main. Elsewhere never commit to main. steamify-cachyos: release/X.Y.Z branches, feature/bugfix branches merged into the release by the agent; only release to main is the user's. steamify-cachyos-live-iso: PRs always target feat/steamify. Branch cleanup: the steamify-branch-cleanup skill in .claude/skills/.
• Follow and update TESTPLAN.md; every check in share/vmtest/ says which row it covers.
• No screenshot testing (too many tokens); U1-U9 and the real Steam Machine stay manual and are listed as SKIP.

State (2026-09-29; update when it changes)

• scripts/vmtest.sh runs the whole unattended test: boot loaders limine/systemd-boot/grub (vmbootloadertest.sh) and the suites cli, menu, hw, installer, toggles (vmsuite.sh, checks in share/vmtest/). Each passed in its own run: limine 43, systemd-boot 42, grub 42 (with the B1 boot entry check), cli 55, menu 36, hw 77, installer 4, toggles 42 checks.
• 2026-09-29, on the PC (WSL2): the first complete parallel run, 328 pass, 0 fail in 18 minutes (base image + qcow2 overlays, own ssh port per job, package cache, VM_MEM=4G, MAX_PARALLEL=3; 5 worked on the 9800X3D). On a new machine: one full scripts/vmtest.sh --screen, read ~/vms/last-test.txt, fix what fails.
• Open work: TODO.md (the CEC driver download, the GitHub Actions workflow, P3).

Releases (2026-09-29; details in the steamify-iso-release skill)

• Steamify: release/X.Y.Z -> PR into main (the user's) -> GitHub release, and the same workflow on the Gitea mirror. A new Steamify release starts the ISO's release (ISO_DISPATCH_TOKEN); a CEC driver download is cached.
• The ISO: GitHub makes the tag vX.Y.Z-[dev.]YYYY.MM.DD-HHMM (UTC) and a release with the notes; the Gitea mirror (git.upriser.nl, pull mirror, 10 min) builds on that tag and attaches the 3.2 GB ISO, named after the tag. A release that exists only on the mirror is deleted by its next sync: the tag must come from GitHub.
• Merged feature/bugfix branches are deleted at once (gh pr merge --delete-branch). Push every commit.

Where the tests run

The tests run on the user's PC (Ryzen 9800X3D, 64 GB, WSL2), started from a laptop over ssh (the user's own skill, or scripts/vmtest-remote.sh <ssh-host> [args]: pulls the pushed branch there, starts vmtest.sh --screen, waits for ~/vms/last-test.txt). WSL specifics (access ssh wsl = root@10.0.0.36, keep the Arch window open or WSL shuts down, syncing from the laptop, the podman ISO build, VM windows through WSLg, output in the user's WSL terminal, no GPU passthrough): .claude/skills/wsl-build-host/SKILL.md. vminstall.sh works there without udisks (losetup as root).

Problems found in the Steamify ISO (fix in steamify-cachyos-live-iso, PRs into feat/steamify)

• Fixed (PR #2): cachyos-installer's bootctl install runs in a chroot and writes no EFI boot entry, so systemd-boot only booted through the disk's fallback path (in OVMF after 4-5 minutes of network boot, every boot). steamify-install now registers it with efibootmgr from the live system.
• Fixed (PR #3): /var/log (@log) wasn't mounted when steamify-install ran, so its logs were hidden after boot.
• cachyos-installer leaves systemd-boot with #timeout 3 and no default entry: a real machine waits in the menu for ever (the test setup papers over it in share/vminstall-post.sh).
• It enables ufw, which drops ssh from the host (the test setup runs ufw allow 22/tcp).
• An installed system's package database can be older than what the installer got (mirror skew): a kernel "update" may downgrade. Not a Steamify bug; noted in the vm-install skill.
