policy-scan-notify is now a FreeIPA *user* group instead of a host group,
so alert notifications follow the user to every enrolled machine. The
fetch-alerts timer is installed fleet-wide on any host where the group exists;
the profile.d snippet gates notification daemon start on runtime group
membership (id(1) / SSSD) so non-members log in unaffected.

policy-block-binary-<name> is now a FreeIPA *user* group instead of a host group,
so restrictions follow the user to every enrolled machine. The PATH wrapper is
installed on all hosts and checks group membership at runtime via id(1)/SSSD,
passing non-members through transparently. __ in the group name decodes to .
so Flatpak app IDs are supported (flatpak run fallback included). AppArmor layer
removed since per-user confinement requires a different approach and the wrapper
alone is sufficient. Adds local_sudo_<username> host group policy which writes
a sudoers drop-in granting that user full sudo on the specific device, reverted
on group leave.

Adds a new host group policy `no_local_users` that locks the passwords of root
and all local users (UID >= 1000) via `passwd -l`, ensuring only FreeIPA domain
accounts with centrally-managed sudo rules can authenticate and gain elevated
privileges. Leaving the group reverts by unlocking every account tracked in the
state file. Updates docs with group reference entry and Local User Lockdown section.

ansipa-smb-setup.sh:
- Adds KeyAdmin Linux group and luks-upload service account (member of
KeyAdmin) on the IPA container, both persisted across restarts.
- LUKS base dir /data/luks-keys owned root:KeyAdmin, mode 2750 (setgid
so new files inherit the group).
- New [ansipa-luks-keys] SMB share: valid users = @KeyAdmin, read only,
write list = luks-upload. Human admins gain read access by being added
to KeyAdmin: useradd -r -G KeyAdmin <user> && smbpasswd -a <user>.
- LUKS_KEY_UPLOAD_PASSWORD sourced from env / /data/samba/ansipa-smb.env
alongside the existing SMB_SCAN_PASSWORD.
collect-luks-keys.yml:
- After fetching /_LUKS_BACKUP_KEY from each client, uploads it to the
ansipa-luks-keys share via smbclient using a temp credentials file
(no_log, deleted in post_tasks).
- Local staging copy is removed after a successful upload.
- SMB credentials file uses an epoch-stamped path to avoid collisions.
.env.example: documents LUKS_KEY_UPLOAD_PASSWORD.

Host groups named policy-daemon-enable-<unit> and
policy-daemon-disable-<unit> are now matched by a wildcard case arm in
the group parser — no per-service configuration required.
Enforcement (every 30 min via existing timer):
enable: systemctl enable --now <unit>; state written to
/var/lib/ansipa-policies/daemon-enabled
disable: systemctl disable --now <unit>; state written to
/var/lib/ansipa-policies/daemon-disabled
revert: when a host leaves a group the opposite action is applied
on the next run (enable→disable, disable→enable)
conflict: unit in both lists is skipped with a warning
The .service suffix is optional — _svc_unit() appends it when the name
contains no dot, so all systemd unit types work as-is.

ansipa-smb.service: WantedBy=multi-user.target (was smb.service) so the
setup service always runs at boot, not only when smb.service pulls it in
docker-compose.yml: add NetBIOS UDP ports 137/138 to match Dockerfile EXPOSE
and nmb.service being enabled
ansipa-smb-setup.sh:
- use printf '%q' when writing SMB_SCAN_PASSWORD to ansipa-smb.env so
passwords with spaces or shell-special chars are correctly quoted
- always write /etc/cron.d/ansipa-check-scans (remove the [[ ! -f ]] guard)
since /etc/cron.d is on the ephemeral container layer and is lost on
container recreation; the service runs on every start anyway
Dockerfile: add -e SMB_SCAN_PASSWORD and -p 445:445 to the quick-test comment
ansipa-fetch-alerts.sh: replace $NEW && log with [[ "$NEW" == true ]] && log
to avoid set -e ambiguity with the 'false' builtin

Container (ansipa image):
- Add samba + cronie to Dockerfile; expose ports 445/139
- ansipa-smb-setup.sh: idempotent setup of smbd + scanupload user +
/data/scan-results/{archive,alerts}/ on every container start
- ansipa-smb.service: runs setup before smb.service on each boot
- ansipa-check-scans.sh: hourly cron on server; analyses archive logs for
ClamAV/rkhunter/chkrootkit findings and writes <host>/<date>.alert files
- docker-compose.yml: add SMB_SCAN_PASSWORD env var + port mappings
- .env.example: document SMB_SCAN_PASSWORD
Client (policy-security-scan):
- Scan script now uploads log to //ipa-server/ansipa-scans/archive/<host>/
via smbclient after each run
Client (policy-scan-notify — new policy group):
- ansipa-fetch-alerts.sh: root timer (10 min) downloads alerts from SMB into
~/administration/<hostname>/ for each active login session; deletes server
alert when user removes local file (acknowledgment)
- ansipa-scan-notify.sh: user daemon started via /etc/profile.d/ansipa-notify.sh;
sends notify-send every 10 min while *.alert files remain in ~/administration/
- deploy-ansipa-policies.yml: installs samba-client, deploys SMB creds file
(/etc/ansipa-smb.creds, 0600), and deploys both notification scripts

Binary blocking now applies two layers:
1. PATH-priority wrapper in /usr/local/bin/ (existing)
2. Empty AppArmor profile in /etc/apparmor.d/ loaded in enforce mode
An empty AppArmor profile denies all access — the blocked binary cannot
load shared libraries and exits immediately with a permission error,
covering callers that use absolute paths and bypassed the wrapper.
AppArmor layer is skipped silently when apparmor_parser is not present,
and deferred with a warning if the real binary is not yet installed.
Profiles are unloaded and deleted when the host leaves the policy group.

New playbook collect-luks-keys.yml connects to all enrolled FreeIPA
clients, checks for /_LUKS_BACKUP_KEY (placed there by the installer
when encryption is enabled), and fetches each key to the Ansible
controller as luks-keys/<HOSTNAME>_LUKS_BACKUP_KEY (mode 0400).
Hosts without the file are reported but not treated as errors.
The luks-keys/ store directory is created with mode 0700.
Usage:
ansible-playbook -i inventory collect-luks-keys.yml
Can be scheduled via cron on the controller for automatic collection.

IPA group naming: fp_install_org__mozilla__firefox (dots encoded as __)
Decoding: sed strips prefix, then s/__/./g restores the Flatpak app ID.
Single underscores in app IDs are preserved unambiguously.
ansipa-install-flatpaks.sh:
- kinit with host keytab, queries ipa group-find --pkey-only with awk $NF
- Validates decoded ID against reverse-domain regex before installing
- Ensures flathub system remote exists
- System-scope install (flatpak install --system) since service runs as root
- Timer offset to 4 min (after packages at 2 min) to avoid contention
deploy-ansipa-install.yml updated to deploy the Flatpak script, service,
and timer alongside the existing package installer.

- Add freeipa-client module (sssd, cyrus-sasl-gssapi, freeipa-client AUR)
with post-install enrollment hints; wired into tui-install.sh and
install-modules.sh
- Add ansipa-install-modules.sh: reads IPA host groups named
ansipa-module-<name>, applies matching module scripts via a yay wrapper
that drops to ANSIPA_USER so AUR builds work from the root service
- Add ansipa-install-modules.service + .timer (boot + 30 min)
- Add deploy-ansipa-modules.yml Ansible playbook that deploys scripts,
writes /etc/ansipa-modules.conf, and enables the timer
