Home is now Overview | My Home | Phone. Overview leads with quick-action tiles (focus, Do Not Disturb, health, snapshots, storage), keeps the findings card — updates fold in, the reclaim-space prompt is gone on purpose — and adds glance cards, the next calendar event, and weather. My Home groups every light by Home Assistant area: the helper gained an `areas` command (one REST template render, no websocket), and the rooms degrade to a flat list on setups without areas. The favorites editor and connection card moved intact. Phone gains a vitals strip — battery and cell signal read from KDE Connect's plugin D-Bus objects, where absence is data, not an error — beside ring, clipboard, send-a-file, and the BlueBubbles handoff. The retired home-phone id resolves to my-home forever via a new alias map in SettingsRoutes (with a hasOwnProperty guard so prototype names cannot leak into settingsPage). Storage no longer claims 0 B free — the old page read a field the disks helper never emitted. Contracts updated alongside; per the new workflow, the full suite runs once at the end of the redesign (see the test backlog note).

"""Generate the settings reference from PreferenceSchema.qml.
|
||
|
||
Every other form of documentation in this repository has drifted at least once:
|
||
routing that pointed at a page not containing the setting, contracts that pinned
|
||
the bug they were meant to prevent, and a comment that failed to stop the person
|
||
who read it making the exact mistake it warned about. Prose describing 137
|
||
settings would drift the day after it was written.
|
||
|
||
So this is generated, and a contract fails when the committed copy no longer
|
||
matches what the schema says. The document cannot be wrong for longer than it
|
||
takes to run the suite.
|
||
|
||
Usage:
|
||
panama-settings-docs write docs/settings.md
|
||
panama-settings-docs --check exit 1 if the committed copy is stale
|
||
panama-settings-docs --stdout print without writing
|
||
|
||
Where each group of settings lives comes from SettingsSearch.qml's routing and
|
||
SettingsRoutes.qml's taxonomy, so a page renamed or moved into another category
|
||
is renamed here too rather than in a list somebody has to remember.
|
||
|
||
Parsing rather than importing: the schema is QML, there is no QML interpreter
|
||
here, and a regex reader that FAILS LOUDLY when it stops recognising the file is
|
||
better than a dependency on a shell that has to start a compositor.
