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

Wonder Ink printing

Under the lab's real Plasma session, driven with the pointer. See wonder-ink.md, Printing.

pic-preview-default, pic-preview-half-topleft	a picture in a tab of its own, laid out on Letter: as large as fits, then 50% top left (0.2.6.2)
print-image-menu	right-click on a picture inside a lesson: Print image… and Print page…; on the words there is only Print page (0.2.6.3)
print-image-bw-half-topleft	Print image on a signed-in picture, 50% top left, Black and white — the preview grey, as the job CUPS kept was (0.2.6.3)
workspace-restored	Wonder Ink reopened after an accidental close: the lesson's WonderInk tab at its sign-in page, its slide in front, its PDF behind (0.2.6.4, the real site)

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
