ekklesiaandClaude Opus 5 7f4a122900 feat: one setting per application, and never the shape of the machine
A laptop is going in for the women's Bible study, and the obvious way to
build that — a laptop profile that turns off the children's church
applications — is the wrong way. A laptop may well take children's church,
and a tower may well be a Bible study. Hardware cannot be allowed to
decide purpose, so every optional application gets a setting of its own:

    WONDERINK_ENABLED       already existed; behaviour unchanged
    DVD_ENABLED             new
    PARENT_CALL_ENABLED     new

and DEVICE_TYPE says only what the hardware IS. classroom-desktop-layout
never reads it, and there is a test that says so, because this is the rule
that will be under pressure the first time somebody adds a device.

All three default to true, so an existing classroom that has never heard
of any of them comes up exactly as it did before. The settings are
appended to device.conf by the same mechanism every other setting has
used, so an upgrade gains them without losing a byte an administrator
wrote.

The disc player is the one place hardware still votes, and it is a veto:
DVD_ENABLED can take the player away from a machine that has a drive,
nothing can put it on a machine that has none. A button that cannot work
is worse than no button.

The layout's launcher markers are replaced by a feature block of three
plain booleans. The old mechanism commented a line out of an array, which
worked for launchers and could not express Parent Call, because that is a
whole widget rather than one entry. Three booleans express both, and the
launcher list is now built from them in one fixed order, so a disabled
application closes the row up rather than leaving a gap, and the same
enabled set produces the same bar on every machine in the church.

Also here, because it is the bar and not a feature: sortingStrategy=0.
Plasma's default is 1, "manually", and the task manager accepts a
reordering drop only in that mode — MouseHandler.qml tests
tasksModel.sortMode === SortManual before it will move anything. The
classroom never wrote the key, so it had the default, and any teacher
could drag the launchers into a different order. This is the applet's own
lever refusing the drop rather than something of ours putting the bar back
afterwards.

The test now runs the layout the package actually ships, in node, with
Plasma's API stubbed, and asserts the launcher string that comes out.
Asserting against a copy of the file's text in the test was how the old
one worked, and a copy is a thing that drifts.

Screenshots from the classroom v2 experiment

All 1920×1080, captured with grim from a real running session in the container lab. See ../classroom-v2-experiment.md.

The desktop

v2-idle-desktop the idle desktop: the wallpaper, one bar, nothing else
v2-from-package the same desktop, produced by installing the .deb on a clean machine
v2-dark-bar, v2-light-bar the bar in both themes
v2-theme-compare the two, one above the other
v2-testpage a maximised browser, edge to edge above the bar
v2-wonderink Wonder Ink as an application, in its own profile

Application state

state-1-closed both launchers closed: no indicator
state-3-behind one active (teal), one running behind it (grey)
state-4-minimized minimised — measured identical to behind, which is why minimise was removed as a route
state-5-restored back
v2-both-apps both applications, one button each, from the packaged install
labelled-tasks the labelled task manager, evaluated and rejected: it shows changing page titles rather than application names

Wonder Ink with tabs

0.2.1. A teacher prepares a lesson across several tabs, and none of a browser's other furniture is on the screen.

wonderink-tabs [ Lesson ] [ Video ] [ Activity ] — the second and third opened by the lesson itself, one through target=_blank and one through window.open
wonderink-one-tab one tab, and no strip at all: the room looks exactly like the application this replaced
wonderink-tab-closed the middle tab closed; the other two carry on
wonderink-fullscreen a lesson's video over the whole display, panel and tab strip included
wonderink-after-fullscreen and back, maximised above the bar, tabs intact — the bug this caught left the window 200 pixels wide in the corner
wonderink-context-menu the whole of the right-click menu: back, forward, reload, print. No view-source, no save-page, no new window
wonderink-print-dialog a lesson calling window.print(), landing on the room's own Elmer queue
wonderink-and-browser the point of the split, in one picture: Chrome in front with its address bar, Wonder Ink a separate button beside it
wonderink-autoplay, wonderink-autoplay-control the Present-view autoplay failure reproduced and then not reproduced: an unmuted video started by a script with no gesture, blocked at Chrome's default and playing as shipped
wonderink-packaged the packaged shell against the real app.wonderink.org, launched from the .deb on a rebooted machine
wonderink-disabled WONDERINK_ENABLED=false — no lesson button, the browser and the disc player where they were

Wonder Ink worksheets

0.2.2. A lesson link that downloads a PDF comes back as a tab, and nothing else about the room's locks moves.

pdf-opened the worksheet a click downloaded, open as a tab beside the lesson and actually rendered — three pages, not a blank frame
pdf-page2 page 2 of 3: multi-page navigation inside the tab
pdf-spaces Leader Guide, Week 1 (Advent).pdf — spaces, a comma and brackets, through the download and into a tab
pdf-print printing the worksheet, on the room's own Elmer queue
pdf-closed-then-page the worksheet tab closed, the lesson still there and still working, and an ordinary target=_blank tab beside it
pdf-broken HTML the server called .pdf: refused on its contents, with a message, and no blank tab
pdf-interrupted a download that did not finish, saying so. The first version of this said nothing at all
pdf-guard three attempts to reach a local file from the page — a link, a script, and a link to a worksheet that was downloaded but not opened by the shell. All refused
pdf-dotmenu the whole of the PDF viewer's overflow menu, audited: two-page view, annotations, present, properties. No open, no save-as, no external link
pdf-after-save the viewer's own download button: straight to Wonder Ink's directory with a notification, no file chooser and no duplicate tab
pdf-autoplay-preserved the 0.2.1 Present-view autoplay fix, still working on the packaged 0.2.2

Parent Call

pc-icon-vs-notifications the Parent Call mark beside Plasma's notification bell — the comparison that decided it
pc-mark the mark at 32, 48 and 64px, beside the two marks it replaced
pc-panel the whole bar: Parent Call left, applications centre, status right
pc-ready the card, ready, in approval mode
pc-waiting waiting for a volunteer to approve
pc-sent Sent to sanctuary — never "displayed"
pc-rejected not approved, offering Try again
pc-off the coordinator's mode is off
pc-nobroker the broker is unreachable
pc-typed a name in the field
icon-candidates-2 sixteen Breeze person icons at real panel size, none of which meant Parent Call

DVD

dvd-panel DVD in the row with the applications, out of the status area
dvd-cover the DVD launcher's tooltip on the packaged install
v2-dvd-overlay, v2-layershell the loading cover: a gtk-layer-shell overlay under KWin

Windows

v2-secondary-window a window a page opened, floating over an untouched browser, with its own close button
v2-print-dialog the system print dialog, over the page that raised it, offering only Elmer
v2-fullscreen fullscreen video: the whole display, panel covered
v2-layershell a gtk-layer-shell overlay under KWin — what the DVD loading cover is made of
v2-notification-crop a notification card, top right

Administration

admin-terminal the maintenance terminal, opened by its chord's action
admin-terminal-bar the bar with the terminal open, and after closing it: a task button while it runs, no launcher ever

Reliability and lockdown

recovery-after-8-kills the panel after eight consecutive SIGKILLs
recovery-after-kwin-kill the session after KWin was killed twice; the application window survived
recover-panel the bar rebuilt from the layout script after its configuration was deleted
lock-desktop-rmb right-clicking the wallpaper: no menu
lock-panel-rmb right-clicking the bar: no menu
lock-krunner KRunner asked for, and not there

The migration

migration-before what a real room got when it upgraded: stock Debian Plasma, kickoff, a pager, a system tray, the Debian wallpaper. Reproduced in the lab by taking one line out of the harness.
migration-after the same machine after the fix — a Hyprland-era install, upgraded, rebooted
migration-after-bar its bar, at the size a teacher sees it
migration-parent-call Parent Call on the migrated machine, saying it cannot reach the church network rather than pretending it can
theme-light-live, theme-light-after-logout the room's own light theme, and the same room after logging out and back in. The first attempt at this pass lost it.

The rooms themselves

v2-from-package the classroom with the church's own wallpaper and the real Wonder Ink mark
wonderink-icon the same mark as a running application's button
display-settings the hidden display-size dialog, saying that saving needs an administrator
scale-200, scale-200-notification, scale-200-chrome the room at 200%: the panel, a notification card, and the browser, all doubled together
notification-style the notification card on the classroom's own Plasma style
osd-volume Plasma's volume display, which the room keeps
osd-shellpackage the custom one, which rendered correctly and cost the panel
pc-unreachable, pc-not-configured Parent Call telling a broker it cannot reach from one that was never set up
dvd-absent-bar the bar on a machine with no optical drive

A morning in the rooms

pc-no-mode Parent Call ready against a broker with no retained mode — the state that used to say the room was never set up
pc-bottom-left, pc-200-package the card anchored bottom-left at 100% and at 200%
notif-package-100, notif-package-200 the notification card at both scales, from Classroom
notif-13pt, notif-15pt the two font sizes that were weighed for it
pc-typed-layer the card gone: the lab's keyboard tool closes it, which is why typing is still a bench test

Failures, kept

— keyboard injection never reached the nested session, so every interaction in this experiment was driven by the pointer. It is why Parent Call has never had a real key pressed into it, and why that is the first bench test.
m-closed, m-minimized the pair whose pixels were sampled to show that Plasma draws minimised and closed differently, but minimised and behind the same
