On the laptop the browser jumped behind the disc player the moment it was
opened. 0.2.4 caused that, and the cause is two lines of the stock applet:
main.qml:153 hideActivatedLaunchers: tasks.iconsOnly || ...
main.qml:155 launchInPlace: tasks.iconsOnly && sortingStrategy === 1
For an icons-only bar the first is always true — a launcher is hidden the
instant its application starts — and the second is what puts the running
window back where the launcher was. It only does that at sortingStrategy
1. 0.2.4 set it to 0 to stop teachers dragging the icons about, so the
launcher vanished and the window was appended after the others.
Reproduced in the lab with a real Chrome window before changing anything,
and the bar read off the screen: Wonder Ink, the player, then the
browser. With 1 it is Wonder Ink, the browser, the player, through
opening, a second window, another application opening beside it, and
every close.
The launcher identity was suspected and cleared: only one browser button
appears, because google-chrome.desktop already carries Chrome's own file
name and StartupWMClass for exactly this reason.
THE COST, AND IT IS REAL. Manual sorting is also the only mode in which
MouseHandler.qml accepts a reordering drop, so a teacher who knows to drag
can rearrange the bar again. There is no value that gives both and no
Kiosk key that separates them. classroom-desktop-reset already rebuilds
the bar from the package at every login, so a drag never outlives the
session. docs/testing.md states the trade rather than burying it, and the
configuration escape is written down there too as still open.
tools/lab/order-check is the test this needed and did not have. 0.2.4
passed a full set of configuration assertions while the bar did something
else, so this one opens real application windows and reads the panel
strip as pixels — there is no image library in the lab, so it captures
PPM and names each icon by colour. Six checks, all of them behaviour.

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 |

Parent Call telling a broker it cannot reach from one that was never set up |
dvd-absent-bar |

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 |
