It was set up display-only, with alsa_device "simulate", so the UI showed a
working player that made no noise - but the Pi has a HifiBerry amp and
pi_alsasetup already put the softvol_effects slot on it. Point the backend at
it, the same way musicmouse does: a softvol control feeding dmix, so the card
stays shared with squeezelite and shairport instead of being locked.
Carry musicmouse's volume clamp over with it. Below roughly 23 the softvol
attenuation leaves nothing audible, and the ceiling keeps a UI slider from
putting the amp to full. Those numbers are tuned to musicmouse's speakers and
this is a different room, so they are a starting point.

musicmouse_version pointed both hosts at rearchitect-backend, a branch that only
ever existed on a laptop - so the previous commit's rework could never actually
have run. Point each host at a deploy/<host> branch on the remote instead. Those
branches are the deployment record: what is installed on that box right now,
moved with a force-push when you mean to deploy.
musicmouse (Kinderzimmer) is the reason this matters. It is in daily use and
still runs the pre-rearchitecture backend out of /opt/musicmouse_venv and
espmusicmouse/host_driver/main.py. That commit has no python-backend/
pyproject.toml, no python-backend/musicmouse.service and no web/ at all, so this
role cannot install it - and a run would have force-checked-out incompatible
code over a working device first and failed afterwards. Set
mediapi_install_kidsmusic: false there and leave it alone;
deploy/musicmouse records the commit that is installed, for rollback. Add a
stat + fail right after the checkout so the same mistake stops with an
explanation instead of failing three tasks deeper.
Also in the role:
- Install the typing game's curriculum next to config.yml. A config with a
tippen: section refuses to start without it - curriculum_file is validated as
must-exist - so musicdolphin's new config needs it present.
- Stop clobbering config.yml. The app writes to it at runtime: parent mode
patches the volume keys and the remote-control page rewrites the remote:
block. A plain copy: undid that on every run. Install-once by default, with
-e pi_musicmouse_force_config=true to push a change deliberately.
- Fill out config-musicdolphin.yml against the current schema: library root and
cache, an absolute static_dir (../web/dist would resolve to /media/web/dist
from /media/musicmouse and silently serve nothing), tippen, and the volume
range for a screen-driven instance. ha: is left commented out until the
Wohnzimmer-oben entity ids are picked - the ones in the dev config are
Arbeitszimmer. No mqtt: (it would publish a device of dead entities on a
simulate-only host) and no lirc:/remote: (this host runs irserver, a serial
daemon, not the lircd this speaks TCP to).
The curriculum is a verbatim copy of app content, so exclude it from
ansible-lint rather than reformat it away from its source.

The app grew a python-backend/ and a web/ frontend, so pi_musicmouse no
longer matches it. Rework the role:
- Install a pinned uv and build the venv with Python 3.13; Raspbian
Bookworm's python3 is 3.11 and the backend uses PEP 695 syntax.
- pip install python-backend/ instead of a requirements.txt, and take
the systemd unit straight from the checkout so it can't drift.
- Build web/ on the control machine (no npm on the Pi) and rsync
web/dist over. Chain the checkout -> install -> build -> sync -> restart
steps through handlers so a run with no repo change does nothing.
- Per-host config files (config-<host>.yml); the schema now differs
between a host with a real mouse and a display-only one.
- Version to deploy is per host (musicmouse_version), no default.
Add pi_kiosk: autologin user running startx with Firefox in kiosk mode
and no window manager, for a Pi with a monitor attached. Enabled by
mediapi_has_monitor, defaulting off.
Turn musicdolphin into a display-only instance: serial and audio
simulated, driven entirely through the kiosk page.
