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.

- 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.
