ekklesiaandClaude Opus 5 18cf0249dd feat: give Parent Call a mark that says what it does
Three marks were put on a real panel and judged at the size the bar
actually draws them. A bell sat inches from Plasma's own notification
bell and meant something entirely different. A handset with an outgoing
arrow read as a telephone feature. Breeze has people and it has
telephones and the two never meet, so this is drawn in Breeze's language
instead: an adult, a child, and one small speech bubble, on Breeze's
22-unit grid with its ColorScheme-Text class, so it recolours with the
session and needs no second file for the light theme.

Quick Launch carries it. The Icon widget copies the entry into the user's
home so an update could never change it; a task manager reads the entry
live but also shows every running window, which filled the auxiliary
corner with the lesson's tasks.

One defect found on the way, and it affected the Wonder Ink icon that is
already shipping: gdk-pixbuf recognises an SVG by sniffing the first
bytes, and a licence-length comment above the opening tag pushes it out
of that window. Every GTK program reported "couldn't recognize the image
file format" while Qt rendered the same file happily. The comments live
inside <svg> now.

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

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

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

Failures, kept

wtype-probe keyboard injection never reached the nested session, so every interaction in this experiment was driven by the pointer instead
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
