The role left musicdolphin with an empty venv and a service crash-looping on
ModuleNotFoundError while ansible reported failed=0, because installing the
backend hung off a handler notified by the git checkout:
- the run where the checkout changed failed later on, so handlers never
flushed and the notification was dropped;
- the next run found the checkout already current, notified nothing, and
installed nothing.
Nothing ever converges from there. Make it an ordinary task that runs every
time - uv is fast when there is nothing to do, and its output says whether it
actually installed anything, so a restart is still only notified on a real
change. Give the frontend the same treatment with a cheap stat, since the build
chain has the identical hole and a device with no dist serves no UI.
Also add libjpeg-dev and zlib1g-dev: Raspberry Pi OS has a 32-bit userland,
Pillow publishes no armv7 wheel, and uv therefore builds it from source.

pi_standard_setup's defaults set `ansible_become: true`. Role defaults are
play-wide host variables, and in Ansible's precedence the `ansible_become`
variable outranks the `become` keyword - so the `become: false` on every
pi_musicmouse task delegated to localhost was silently overridden and each one
tried to sudo on the machine running ansible:
Premature end of stream waiting for become success or become password prompt
Those defaults earn their keep bootstrapping a fresh Pi, where you connect as
`pi` and become root to enable root login, so override the variable on the
delegated tasks rather than removing them.

Removing the SSH banner only hid the symptom. userconfig.service is a
Type=oneshot unit that runs
whiptail --inputbox "Which user would you like to rename:" 20 60 pi
on tty8 and waits for an answer, which on a headless Pi never comes - it had
been sitting in "activating" for four and a half hours on musicdolphin. It is
WantedBy=multi-user.target, so that target never finished activating either, and
the boot job for it was still queued from boot. Anything ordered
After=multi-user.target then gets a start job that queues behind it and hangs
forever: musicmouse.service never started, and the ansible task that starts it
blocked until killed.
The pi user already exists on these images, so the wizard has nothing to do.

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.

Under --check the git task reports "changed" without writing anything, so on a
host that has not been deployed yet there is no checkout to stat and the guard
fired on a perfectly fine configuration - making `just check mediapis.yml
musicdolphin` fail before the first real run.

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.

raspi-config's do_hostname rewrites the 127.0.1.1 line with
sed "s/127\.0\.1\.1.*$CURRENT_HOSTNAME/127.0.1.1\t$NEW_HOSTNAME/"
which only matches if that line already holds the *old* hostname. Ours
still said "raspberrypi", so the substitution has been silently doing
nothing and the box could not resolve its own hostname.
Set the line explicitly instead, after the hostname is re-read, so a
rename and this update happen in the same run.

The Pi is gone; the name no longer resolves. It was still picked up by
the "hosts: all" playbooks (update-packages.yml, test_keepass.yml),
where it showed up as unreachable on every fleet run.
It was also the only host pointing pi_squeezelite_squeezeserver at
192.168.178.100 (musicdolphin) rather than the central server at .80,
so nothing depends on musicdolphin's LMS instance any more.
The "esszimmer" rows in roles/bluetooth_monitor/other/*.csv and the
analysis notebook are room labels in historical sensor training data,
not this host, and are left alone.

The Pi's OS hostname was changed first (raspi-config do_hostname +
reboot), since no mediapi sets ansible_host and Ansible resolves these
by hostname via mDNS/router DNS. Host now answers as musicdolphin.local
at 192.168.178.100.
The motd file must match the live OS hostname (pi_standard_setup reads
it off the device), the host_vars filename and the pi_musicmouse config
filename must match the inventory key.
sensor_room_name/sensor_room_name_ascii stay WohnzimmerOben - they name
the physical room for MQTT topics, not the host, and renaming them would
orphan the Home Assistant history.

Skipped command tasks return stdout: "" rather than being undefined, so
"src: motd/{{ ...stdout }}" collapsed to "motd/" - a directory - and copy
switched to recursive mode, failing with "/etc/motd/<file>: Not a
directory". The empty boot-target stdout likewise never equals
"multi-user.target", so "Set boot mode to CLI" always reported changed.
Run the three read-only commands in check mode. They are all
changed_when: false already, so this is safe.

Several roles reported "changed" on every playbook run even when
nothing on the target had drifted, making real config drift
indistinguishable from noise:
- 7 systemd tasks across 6 roles used state:restarted, which always
issues a restart and always reports changed. Switched to
state:started plus notify-driven handlers that only restart when
the underlying unit file, script, or config actually changes.
- pi_standard_setup's boot mode, timezone, and locale tasks shelled
out to raspi-config with changed_when:true hardcoded. Boot mode now
checks systemctl get-default first; timezone/locale now use the
natively idempotent community.general.timezone/locale_gen modules.
- The pi account password task computed password_hash('sha512')
without a seed, generating a new random salt (and thus an
apparently different hash) on every run. Added a stable seed so the
hash only changes when the underlying secret does.
Also renamed a mislabeled task in pi_squeezelite_custom and fixed a
typo in pi_standard_setup while those files were already touched.

Regular playbooks now use state: present, so they no longer upgrade
packages as a side effect. This adds two separate, explicit mechanisms
to keep the fleet patched instead:
- update-packages.yml: ad hoc / to-be-scheduled fleet-wide upgrade
(safe by default, dist available via -e), plus
update-packages-pinned-example.yml as a template for pinning or
bumping a single package outside that.
- roles/unattended_upgrades: automatic security-only patching via
unattended-upgrades, with a scheduled reboot window and mail
left disabled pending a configured MTA. Applied to every host in
full.yml and server.yml.
Also removes a leftover `upgrade: yes` apt task from pi_standard_setup
and server_basic_environment that was still doing a full upgrade on
every routine run, defeating the point of the state: present switch.

- risky-file-permissions (32): add explicit mode: to copy/template/file tasks,
matching the umask-derived permissions they already had (0644 for configs
and systemd units, 0755 for created directories) — no functional change.
- var-naming (28): prefix role-scoped vars with their role name across
pi_dhtsensor, pi_dhtsensor_circuitpython, pi_shairport, pi_squeezelite,
pi_squeezelite_custom, pi_sispmctl, pi_standard_setup, and pi_sysdweb's
sysdweb_name (shared by 9 consuming roles). Updated every dependent
template, task reference, and matching inventory.yml override, and
verified resolved values with ansible-inventory before/after.
- Fixes a latent bug found while renaming: pi_standard_setup's "Get/Change
WiFi country" tasks reused the name wifi_country for both the role default
and a register, so the register silently clobbered the default before
do_wifi_country ever read it. Split into distinct names so the intended
default value is used.
- package-latest (2): pin docker-ce/docker-compose-plugin installs in
server_debian_docker to state: present.
- no-handler (1): move pi_lirc's "Reboot if boot overlay changed" into a
proper handler notified by the boot-overlay task.
ansible-lint now passes clean at the production profile.

The .ansible directory is a local ansible-galaxy/ansible-core cache
that got swept into the previous commit by git add -A. Also update
the pi-squeezeserver backup ignore path to match the role rename.

- Auto-fix FQCN, YAML formatting, jinja spacing, and free-form module
syntax via ansible-lint --fix
- Fix comments misplaced inside module args by the auto-fixer
(bluetooth-monitor, pi_standard_setup, pi_musicmouse)
- Fix notify: references left stale (lowercase) after handler names
were re-cased, which would have silently broken reboot/restart
handlers (pi_disable_onboard_bluetooth, pi_hifiberry_amp,
pi_squeezelite, pi_standard_setup)
- Fix a task in pis/debmatic-install.yml missing its module name
(apt_repository), which caused a real syntax-check failure
- Add missing play names, fix comment spacing, literal-compare idiom,
and no-changed-when annotations
- Delete unused/broken roles/better-shell-env (unreferenced, invalid YAML)
- Rename all hyphenated role directories to underscore form to satisfy
ansible-lint's role-name rule, updating every playbook/meta reference
Remaining lint findings (var-naming, package-latest, risky-file-permissions,
no-handler) intentionally left for follow-up per user decision.
