Raspberry Pi OS ships a 64-bit kernel with a 32-bit userland, so uname -m - and
therefore ansible_architecture - reports aarch64 on a box whose /bin/ls is
ELF32 ARM and which has no /lib/ld-linux-aarch64.so.1. The aarch64 uv tarball
unpacked happily and then failed three tasks later with
/usr/local/bin/uv: No such file or directory
which is the dynamic loader missing, not the file, and points at entirely the
wrong thing. Pick the target triple from ansible_userspace_bits instead, which
is the fact that tells the truth, and key the install directory on the triple as
well as the version - otherwise `creates:` would keep a wrong-architecture
binary in place forever. Then run `uv --version` right after installing it, so a
bad download fails where the cause is visible.

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.
