Records the exact stable base commit, the fact that the development host cannot create a VM, and the first measurement worth having: Debian 13 already ships Plasma 6.3.6. Co-Authored-By: Claude Opus 5 <[email protected]>

Classroom v2 architecture experiment
An open re-evaluation of the whole Ekklesia Classroom desktop stack, with reliability as the first requirement. Nothing here reaches a stable, canary or hyprland room, and nothing here changes the development host.
Base
| branch | experiment/classroom-v2 |
| base commit | aadb1b881977b0eb25e1ca10e060977bed31a48f |
| base subject | fix: keep the system print dialog in front of the window that rendered it |
VERSION at base |
0.1.44 |
That commit is the published stable build, verified rather than assumed:
repo/stable/manifest.json names ekklesia-classroom_0.1.44_amd64.deb with
sha256 7de568...81041, and the copy in repo/packages/ hashes to exactly
that. The branch is not built on experiment/hyprland; git ls-files on it
contains no Hyprland file.
What the experiment must not do
- No change to the development host's OS, packages, partitions or bootloader.
- No in-place distribution upgrade or migration.
- No touching stable, canary, or a real classroom machine.
- Alternate operating systems get a disposable environment or a written VM specification, never the host.
The development host, as found
Recorded because it bounds what can be tested here.
| OS | Debian 13 trixie (13.5), kernel 6.12.90 |
| machine | already a VM — root is /dev/vda2, GPU is bochs-drm, CPU is QEMU Virtual CPU |
| nested virtualisation | none — /dev/kvm does not exist |
| libvirt / qemu / VirtualBox | not installed |
| containers | Docker 26.1.5, cgroup v2, /dev/uinput present |
| resources | 6 vCPU, 11 GiB RAM, 160 GiB free |
Consequence: this session cannot create a virtual machine. There is no KVM and no hypervisor. Every alternate OS or desktop that needs real hardware-level isolation has to be either tested in a container or written up as a VM specification for someone with a hypervisor to run. The previous Hyprland milestone hit the same wall and used containers; that lab worked, and this experiment extends it rather than inventing a new one.
Hypothesis being tested
The classroom's reliability problems — a shell that vanished in production, no minimised-window feedback, secondary windows fighting the main browser, and a growing pile of compositor glue — are all symptoms of having written a desktop environment by hand. A mature integrated desktop already solves each one, and Debian 13 already ships one.
apt-cache policy inside a throwaway debian:trixie container, on the same
archive the classroom already tracks:
| package | Debian 13 version |
|---|---|
| plasma-workspace | 4:6.3.6-2 |
| plasma-desktop | 4:6.3.6-1 |
| kwin-wayland | 4:6.3.6-1 |
| pipewire / wireplumber | 1.4.2 / 0.5.8 |
| vlc | 3.0.23 |
| cups | 2.4.10 |
| chromium | 152.0.7977.82 |
| firefox-esr | 140.15.0esr |
So a full Plasma 6.3 desktop is available without leaving Debian, which
means the entire .deb/apt OTA investment survives the change. That is the
first thing that has to be checked, because if a better desktop required
Fedora or Arch, this experiment would have to stop at a VM specification.
