feat: give Wonder Ink tabs, and let a device say it has no Wonder Ink
Teachers prepare a lesson across several tabs — the lesson, its video,
the activity — and app mode is the one thing that cannot give them that.
Chrome cannot be asked for "tabs but no omnibox". App mode has no tabs; a
normal window has an address bar and no policy, flag or extension removes
it; tabbed web apps need a manifest on a site that is not ours and push
off-origin links out into a normal browser window, which is the whole of
what this design exists to prevent. So the tab strip is ours, and the
engine is Chromium either way.
QtWebEngine, from Debian, measured before it was chosen rather than
after. The usual and correct objection is codecs: on Debian 13 it reports
H.264, AAC, MP3, VP8 and VP9 all playable, MediaSource supports avc1,
mp4a and vp9, and a 720p H.264 file decoded and played to the end in the
lab. app.wonderink.org loads, and its sign-in is an ordinary email and
password form rather than a Google flow that would mind an embedded
browser. The user agent has the QtWebEngine token stripped so a site
gating on it sees the Chromium this actually is, and Widevine is handed
over from Chrome's own bundle when the machine has Chrome, which a
classroom always does.
[ Lesson ] [ Video ] [ Activity ]
The strip appears only above one tab, so an ordinary lesson looks exactly
like the application it replaces. A tab can only come from the lesson —
target=_blank, window.open, a middle click, a Ctrl+click — and there is
no address bar, no search and no button that makes a blank tab. No
allowlist of domains either, on purpose: a list would have to be right
about every video service a lesson might ever embed.
Three bugs the lab caught and this fixes. A lesson calling window.print()
did nothing at all, which is worse than no print button because a teacher
concludes the printer is broken; printRequested is now bound to the page
that asked. Leaving fullscreen left the window 200 pixels wide in the
corner — a window that has only ever been maximised has no ordinary
geometry to return to — so the fullscreen bit is cleared rather than
maximised being re-requested. And the Present view video failure written
up in docs/wonder-ink.md is acted on at last: that investigation named
the autoplay gesture chain as the likeliest cause and declined to fix it,
because in Chrome the only lever governed the ordinary browser as well.
Here it does not — this profile is Wonder Ink and nothing else — so a
lesson may start its own video and no other page in the room may.
Reproduced both ways in the lab with an unmuted video started by a script
with no gesture: NotAllowedError at Chrome's default, playing as shipped.
That is not proof Present view is fixed; the lab has no Wonder Ink
account, and candidates 2 and 3 in that document are still open.
Measured on a rebooted machine, from the package: tabs open from a link
and from window.open, switch, and close; closing one leaves the others;
closing the last closes Wonder Ink; H.264 video plays and fills the
display in fullscreen and comes back maximised with its tabs; the print
dialog offers the room's own Elmer queue; a download lands in ~/Downloads;
back and forward work from a right-click menu that is built rather than
filtered; pressing the panel button twice raises one window rather than
starting a second on the same profile; KWin reports the window as
ekklesia-wonderink, which is one panel button and not two.
Separate from the browser as before, in its own profile, with cookies
that live only as long as the window — what the Chrome policy did for
wonderink.org, and the reason closing Wonder Ink ends a teacher's
session. Chrome's old profile directory is left untouched beside it, and
the browser's own policy is not edited by any of this.
Wonder Ink is now optional per device, through WONDERINK_ENABLED in
device.conf, because one future device is a laptop that will not have it.
It rides the mechanism the disc player already uses: one marked line in
the packaged layout, edited by classroom-desktop-layout. False takes the
launcher off the panel and makes the command refuse to start; the
browser, Parent Call and the disc player are untouched and the panel
stays balanced. Absent means yes, so every existing room is unchanged.
One scale, still. Chrome has to be handed UI_SCALE because it was
measured not to follow the compositor; Qt does follow it — devicePixelRatio
2.0 at UI_SCALE=2.0, measured — so Wonder Ink is deliberately not told,
or the room would get it twice.

fix: a room that was set up, a card where its button is, and larger cards
Parent Call told rooms they had never been set up. Nothing about the rooms was wrong. Read from the church broker: …/coordinator and …/pending are retained and …/mode is absent, and the coordinator's own source says why — it publishes the retained mode only in answer to an operator writing to …/mode/set, and nobody ever has. Every classroom waited a second and a half for a message that will never exist. A missing mode is now read as the coordinator's own default rather than as an unconfigured room: the room offers the call and lets the sanctuary end answer, because that is the end that knows. A mode that really is off still refuses, in the coordinator's words, and a broker that is missing or unreachable still says which of those it is. Proved against a rig broker made to match the church's exactly, with a call landing on the sanctuary mock. The card is anchored to the bottom-left corner instead of centred, by layer shell, which is what the disc player's cover has used under KWin for months. Anchoring rather than positioning is what makes it right at 1080p and at 4K without a coordinate anywhere. It falls back to the centred card if the library is missing. Notifications are sized for a room. Every Plasma measurement is a grid unit and a grid unit is the height of the general font, so the font is the lever — 15 point instead of Breeze's 10, which takes the card from about 350x110 to about 410x145 at 100% and doubles again at 200%. Text, icon, padding and buttons move together. The chime stays off. No shell package: that path cost the panel and is not coming back. And the product name is gone from everything a teacher sees. The notification card is from Classroom, the disc player's from DVD. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat: give every room the broker, one scale, and its own panel back
Little Waders took the Plasma build and reported what a container cannot. A disc player on a machine with no optical drive, a clock nobody at the back of the room could read, a browser at half the size of the panel around it, and Parent Call with no broker to call. The broker is the same for every classroom, so it is a default now and not something to fill in room by room. classroom-migrate brings an existing room to the same place without touching its name, its username or its password, and Parent Call distinguishes a broker it cannot reach from one that was never set up: those send somebody to look at completely different things. The disc player's detection was right and ran too late — alongside the session rather than before it, and the panel is built from the layout the moment a session starts. It runs before the display manager now, and again from udev when a drive is plugged in. UI_SCALE had a ceiling of 1.5, which cannot express a 4K television; a clock pinned at 15 points, which is the same size at every scale; and a browser that was never told the number at all. All three are fixed and the room doubles together at 200%. This also brings 0.1.47's work into the repository, where it had only ever existed in a build directory under /tmp: the hidden display dialog, its authenticated writer, the polkit action, and the church's own wallpaper. One piece of it is deliberately left out. The custom volume display needed a shell package of our own, and with one selected plasmashell builds no panel at all — measured twice, with that build's own files, on a classroom that deletes its panel configuration at every login by design. The lab connected to the real church broker the moment the package defaulted to it. Nothing was left behind, which was checked, but the guard that should have stopped it had never worked: it used iptables, which the lab image does not have, and probed with /dev/tcp under dash, where that always fails. Both reported success. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat: the power button does nothing, and one chord opens a terminal
Two layers for the button, because one is not enough: while a session is running PowerDevil holds logind's handle-power-key inhibitor and acts on the button itself, so a logind drop-in alone would be overruled. logind covers the machine before the session starts, after it ends, and if PowerDevil is not running. Verified: after the drop-in is installed and logind reloaded, it reports ignore for the power, suspend, hibernate and lid keys, and the running session was not disturbed by the reload. Holding the button still cuts the power. That is firmware, below any operating system, and it is deliberately left alone as the only recovery a person standing at a wedged machine has. The maintenance terminal is Meta+Ctrl+Alt+Shift+K, declared in the package rather than seeded into a teacher's configuration, where an update could not reach it. KGlobalAccel read it and registered the component; invoking it opened a working shell. It needed a wrapper. The classroom's Kiosk policy sets shell_access=false and Konsole honours it — measured: with the classroom configuration in its cascade Konsole starts and says "Program to run not set." The restriction is worth keeping everywhere else, so it is lifted for this one process by leaving the classroom's configuration directory out of its cascade. It grants no privilege: the classroom user has no sudo rule, and that restriction was always a barrier in the interface rather than a privilege boundary. Konsole's own entry is shadowed and hidden from /usr/local/share, so nothing is patched and Konsole's package stays maintainable. Nothing is pinned to the panel; a task button appears only while a terminal is open, and closing it returns the bar to three launchers. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat: take the last of sway out of the classroom
The DVD player was the only thing still speaking a compositor the room no longer runs. It asked sway's tree whether VLC's window had really gone fullscreen, because VLC reports playing while its window is still the black startup one the loading cover exists to hide. VLC's own status was measured as a replacement and is not one: it reports fullscreen true in the same 250ms poll as playing, because the flag is the option it was started with and not a report about its window. So the cover is held for a floor and capped by the deadline that was already there, and the compositor is not asked anything. Focus-or-launch went the same way. The session already takes an exclusive lock, so a second one cannot start, and bringing an existing one to the front is the panel's job. classroom-window, classroom_sway and classroom_chrome are gone with it — the last of them was reachable from nothing at all. DVD also moves out of the status row, where it sat beside the clock as though a disc were a machine reading. It is an application: it is in the row with Wonder Ink and the browser, and classroom-provision removes it from the layout on a machine with no optical drive, which retires DVD_ENABLED. A computer that moves between rooms takes its drive with it; nobody remembers to edit a file when it does. The panel is rebuilt from the package at every login now. Plasma keeps whatever panel it first built, so an update could change the bar in the package and never change it in a room — measured, with an icon that outlived the file it came from. Editing the live panel configuration was tried instead and destroyed the panel, because the shell owns that file. Removing it before the shell starts is safe and makes the desktop stateless.

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. Co-Authored-By: Claude Opus 5 <[email protected]> |

fix: let an update change the Parent Call button
Two findings, both from watching the bar refuse to change. The Icon widget copies the desktop entry into the user's home and uses the copy. A classroom that had already run kept the old icon and the old command for ever: the package no longer contained a bell and the bar kept showing one. The button is a task manager holding a single launcher now, which resolves /usr/share/applications live — the place an OTA update writes to — and costs nothing, because the classroom already runs one for the applications. NoDisplay=true then hid the entry from the very index that resolves launchers, and the bar drew a blank page. There is no application menu in this classroom for the entry to clutter, so it is indexable now. Co-Authored-By: Claude Opus 5 <[email protected]> |

feat: let a teacher ask the sanctuary to call a child's parent
The coordinator already existed on the control computer and its contract is frozen, so this is the classroom half of a contract that was read from its README and source rather than guessed: four fields out, the status topic subscribed before anything is published, and every word the teacher reads taken from the coordinator's own message field. It is a separate process, not a Plasma applet. A broker library, a network timeout and a text entry have no business inside the only way a teacher has of getting anywhere; if this dies the bar is untouched. The panel mark is Breeze's call-outgoing. The old one was a bell, sitting two inches from Plasma's notification bell in the same bar and meaning something entirely different. Two things it will not do: claim a call was displayed, and let a teacher type the room. The machine already knows which room it is. Sixty tests cover the contract without a broker. The live path was proven against the real coordinator running in the lab, on a loopback broker, with ProPresenter mocked and the church's networks rejected from inside the container first.

feat: give the classroom a desktop instead of a shell
The whole appliance UI is now configuration for a desktop Debian already ships: a Plasma 6.3 session with a colour scheme, a look and feel package that builds the bar, window rules, and KDE's own Kiosk restrictions. Two things were measured rather than assumed, and both changed a decision. Plasma restarts a crashed panel three times a minute and then gives up, which is the failure a classroom has already had. Four lines of systemd drop-in make it unconditional; the panel then survived eight SIGKILLs a second apart, back each time in 2.4s. Plasma draws a minimised task and a background task identically, so the five states the room needs cannot all be shown. Rather than write a task manager, the classroom removes minimise: clicking a launcher always means show me this. Co-Authored-By: Claude Opus 5 <[email protected]> |
