ekklesiaandClaude Opus 5 a3dba6e8fb feat: provision Chrome and DVD codecs without a manual step
A fresh classroom needed two things installed by hand on every box:
Google Chrome, which is not in Debian, and the DVD codecs, which Debian
cannot ship. Both now happen on their own.

ekklesia-classroom-provision.service runs after every boot and does the
work that needs the network and the apt lock, neither of which a package
postinst can have. Each step returns immediately if it is already done,
so a provisioned machine costs nothing and a machine that was offline
the first time gets another go at the next boot. Nothing there is
allowed to fail the boot: a classroom with no DVD codecs is still a
working classroom, and it says so in the log rather than silently.

The postinst enables the service but deliberately does not start it.
Every OTA update reboots the moment the install finishes, and an apt run
killed by that reboot would leave dpkg half-configured.

Chrome comes from Google's own repository rather than a one-off .deb, so
it keeps getting security updates. Google's package migrates whatever we
write into a deb822 file of its own, so the repository is looked for
across every source file instead of only the one we would write;
otherwise a machine that had Chrome removed would end up with two copies
of the same repository.

The DVD codec helper previously assumed deb822 sources and did nothing
on a machine using a classic /etc/apt/sources.list, which is what the
hardware actually runs. It now handles both formats, and only ever adds
a missing component to an existing Debian entry — so it cannot produce a
duplicate repository or a duplicate component however many times it
runs, and third-party repositories like Chrome's are never touched. It
also answers libdvd-pkg's debconf questions, so nothing blocks on a
prompt in a service with no terminal.

Tested against fixture APT trees for classic sources.list, deb822
.sources, contrib already enabled, repeated runs, third-party
repositories and the awkward real lines: bracketed options, indentation,
trailing comments and flat repositories.

# Classroom test checklist
Run against the exact artifact published to canary, on the real endpoint,
before promoting to stable with `./update_stable.sh`.
## Boot
- [ ] Cold boot reaches the classroom shell with no terminal or window junk
- [ ] Reboot does the same
- [ ] Wallpaper appears
- [ ] Dock appears, centred
- [ ] Clock appears, bottom right
## Provisioning
- [ ] `journalctl -u ekklesia-classroom-provision` shows a clean run
- [ ] Google Chrome is installed on a machine that never had it
- [ ] A second boot does not reinstall anything
- [ ] A machine with no network still boots to a working shell, and
provisioning succeeds at a later boot once it is online
## UI scale
- [ ] `UI_SCALE=1.0` looks exactly as it did before scaling existed
- [ ] `UI_SCALE=1.25`, then `sudo systemctl restart getty@tty1`:
dock, icons, clock and notifications all grow together
- [ ] `UI_SCALE=0.8` shrinks them together
- [ ] The reserved bottom strip grows and shrinks with the dock, and a
maximised Chrome window still stops above it
- [ ] A nonsense value (`UI_SCALE=banana`) still gives a working shell
- [ ] An extreme value (`UI_SCALE=9`) is clamped, not obeyed
## Reserved bottom shell (regression)
The bottom strip is one full-width layer-shell surface with a 76px
exclusive zone. Dock and clock live inside it. Do not split them back
into separate layer-shell windows.
- [ ] A maximised Chrome window stops above the bottom strip
- [ ] The clock does not float over Chrome
- [ ] Dock stays centred, clock stays bottom right
- [ ] Wallpaper shows through the unused parts of the strip
- [ ] Every dock button still responds to clicks
- [ ] A fullscreen application covers the whole display, dock included
## Browser
- [ ] First Browser click launches Chrome
- [ ] Chrome opens on Wonder Ink (https://app.wonderink.org/)
- [ ] Clicking Browser while Chrome is focused minimises it
- [ ] Clicking Browser again restores it **maximised, not floating or draggable**
- [ ] Clicking Browser while Chrome is running but unfocused focuses it
- [ ] `Super+M` minimises the focused window
- [ ] `Super+Shift+M` restores the most recently minimised window
- [ ] Normal navigation to any other site works
- [ ] The Home button returns to Wonder Ink
- [ ] Fullscreen YouTube video uses the whole display
- [ ] Leaving fullscreen restores the correct geometry above the dock
- [ ] No first-run, default-browser or sign-in nag appears
- [ ] `chrome://policy` lists the Ekklesia policies as applied, with no
"unknown policy" entries
- [ ] Chrome does not start by itself at boot
- [ ] After a reboot, cookies and site logins are still there
- [ ] After an OTA update, cookies and site logins are still there
Known limitation: Chrome's own minimise button in its title bar does
nothing. Sway ignores the Wayland minimise request and gives no event to
hook. Minimising is the dock's Browser button or `Super+M`.
## Notifications
- [ ] `classroom-notify-test` renders with the classroom styling:
dark translucent, rounded, white text, top right
- [ ] `classroom-notify-test --critical "Parent Call" "Room 3 needs a parent."`
renders in the critical style and does not time out
- [ ] Notifications appear over a fullscreen video
Over SSH from an administrator account, run it with sudo:
```
sudo classroom-notify-test --dry-run # show the session it resolved
sudo classroom-notify-test # send into the classroom desktop
```
The classroom desktop belongs to the classroom user, and mako sits on
that user's D-Bus session. A plain notify-send from an SSH session lands
in the administrator's own session, where nothing owns
org.freedesktop.Notifications, so D-Bus tries to start a second mako with
no display and the call times out with NoReply. The script finds the
running sway process for the classroom user and delivers into its
session instead. It never starts mako.
- [ ] `sudo classroom-notify-test` from an SSH session displays on the
classroom screen
- [ ] `sudo classroom-notify-test --dry-run` reports the resolved
XDG_RUNTIME_DIR, bus address and Wayland display
- [ ] Running it as an unprivileged admin account explains it needs sudo
- [ ] `tests/test-classroom-notify-test.sh` passes (also run by the build)
## DVD
With `DVD_ENABLED=false`:
- [ ] No DVD button in the dock
With `DVD_ENABLED=true`:
- [ ] Drive unplugged: button present, icon held back, friendly notification on click
- [ ] Drive present, no disc: friendly notification on click, nothing crashes
- [ ] Inserting a disc produces one **DVD Ready** notification
- [ ] The DVD icon comes up to full strength while a disc is in
- [ ] Nothing plays until the button is pressed
- [ ] Clicking plays the disc
- [ ] Menus work
- [ ] Audio works
- [ ] Chapter navigation works
- [ ] Fullscreen works
- [ ] `Super+M` minimises the player, the DVD button restores it
- [ ] Closing the player works
- [ ] Ejecting is detected, the icon goes back
- [ ] Reinserting is detected again
- [ ] VLC opens fullscreen, dark, with no menu bar, no orange cone and
no sway title bar
- [ ] The fullscreen controller still appears on mouse movement
- [ ] Commercial CSS disc plays without anyone having run codec setup
by hand
## OTA
- [ ] `./update_canary.sh` publishes package first, manifest last
- [ ] The endpoint on the canary channel picks the update up
- [ ] SHA-256 verification passes
- [ ] Install succeeds and the endpoint reboots
- [ ] Everything above still works after the update
