 ## Desktop Notes
-- `desktop_profile` names independently selectable desktop groups such as `desktop_gnome`, `desktop_hyprland`, `desktop_sway`, `desktop_niri`, and `desktop_cinnamon`. Keep platform-specific session bootstrap in platform-specific roles.
-- `desktop_environment` selects the mutually exclusive `minimal` (default), `gnome`, `xfce`, or `kde` desktop mode. `profile_desktop_common` owns shared Void bootstrap; the minimal mode uses `profile_desktop_sway`, `profile_desktop_hyprland`, and `profile_desktop_niri`, `profile_desktop_xfce` owns the reproducible XFCE setup, `profile_desktop_kde` owns KDE-specific defaults and cleanup, and `profile_desktop_gnome` copies shared desktop dotfiles for Fedora/GNOME without managing GNOME settings. `desktop_sessions_enabled` and `desktop_default_session` apply only to the minimal mode.
-- Emacs packages and `.emacs.d` deploy are disabled by default via `emacs_enabled: false`; keep the dotfiles in the repo for reversible opt-in only.
+- `desktop_profile` names independently selectable desktop groups such as `desktop_gnome`, `desktop_sway`, and `desktop_niri`. Keep platform-specific session bootstrap in platform-specific roles.
+- `desktop_environment` is fixed to `minimal` for Void desktops. `profile_desktop_common` owns shared Void bootstrap; `profile_desktop_sway` and `profile_desktop_niri` manage the enabled sessions, while `profile_desktop_gnome` copies shared desktop dotfiles for Fedora/GNOME without managing GNOME settings. `desktop_sessions_enabled` and `desktop_default_session` apply to the minimal mode.
+- Emacs has one authoring-oriented `.emacs.d`, deployed by `dotfiles_common` when `emacs_enabled` is true. Fedora/GNOME desktops and workstation profiles enable it; keep platform dependencies in package group vars rather than branching in Emacs Lisp.
 - NTFS filesystem support is provided by `ntfs-3g` in `ansible/inventory/group_vars/void.yml`.
 - Void user services are managed by `turnstile` and live under `dotfiles/desktop/.config/service/`.
 - `ssh-agent` keeps the stable socket `~/.local/state/ssh-agent/socket`.
 - Critical session entrypoints:
   - `dotfiles/desktop/.config/sway/config` plus `host.conf` and `session-env` deployed via `host_sway_dotfiles` (sway / Wayland)
-  - `dotfiles/desktop/.config/hypr/hyprland.conf` plus `host.conf` and `session-env` deployed via `host_hyprland_dotfiles` (Hyprland / Wayland)
   - `dotfiles/desktop/.config/niri/config.kdl` and `session-env` deployed via `desktop_niri_dotfiles` (Niri / Wayland)
 - Void Niri lives in `profile_desktop_niri`, gated on `'niri' in desktop_sessions_enabled`; it installs the `emptty` `niri.desktop` session, the `/usr/local/bin/start-niri` launcher, and the xdg-desktop-portal config, mirroring `profile_desktop_sway`.
 - Fedora GNOME (`desktop_gnome`) assumes GNOME comes from the Fedora Workstation base install; Ansible deploys shared desktop dotfiles and git/GPG config for `ikaros` and `nymph`, not GNOME settings.
-- FreeBSD Niri (dormant; `platform_freebsd` currently has no hosts) must keep FreeBSD-specific package, rc, DBus, seat, portal, and launcher behavior in `profile_desktop_niri_freebsd` or FreeBSD platform vars.
-- Do not switch or restart a display manager during a playbook run from an active graphical session. Changing among `emptty`, LightDM, and SDDM requires an explicit run from another TTY/SSH session with `desktop_allow_display_manager_switch=true`. Apply managed XFCE XML while logged out of XFCE so `xfconfd` cannot overwrite it from its in-memory state.
+- Do not switch or restart the display manager during a playbook run from an active graphical session.
 - `nymph` is the Fedora/GNOME laptop target; keep GNOME settings unmanaged for now and add host-specific tuning only after real use.
 
 ## Void Package And Dotfile Bucket Rules
 `platform_void` is the reusable Void platform selection. The legacy `void` group remains a compatibility parent so existing `group_vars/void.yml` and `when: "'void' in group_names"` checks keep working during the transition.
 The Void desktop package lists in `ansible/inventory/group_vars/void.yml` are kept disjoint by role:
 - `void_packages_base` — system runtime only (init/services, kernel, audio core, networking, filesystem, firewall, hardware daemons, runit logging).
-- `desktop_common_packages` — GUI infrastructure shared by all desktop modes.
-- `desktop_minimal_packages` / `desktop_xfce_packages` / `desktop_kde_packages` — mutually exclusive applications, integration components, and display managers. Packages required by more than one exclusive mode may be repeated; cleanup subtracts the selected mode before removing inactive packages.
-- `desktop_sway_packages` / `desktop_hyprland_packages` — binaries specific to each session. Cross-WM packages used by both (such as `dunst`, `rofi`, and `foot`) are intentionally duplicated in the two lists.
-`profile_packages` in the same file is cross-distro and is overridden by `group_vars/server.yml` and the workstation group vars; do not move desktop-specific Void entries through it.
-The dotfile vars follow the same split: `desktop_common_dotfiles` carries mode-independent content, `desktop_minimal_dotfiles` carries Thunar, Udiskie, and minimal MIME defaults, and `desktop_xfce_dotfiles` carries XFCE state. KDE uses its own MIME defaults. `desktop_void_dotfiles` remains reserved for files that need the Void runtime.
+- `desktop_common_packages` — GUI infrastructure shared by the minimal desktop mode.
+- `desktop_minimal_packages` — applications, integration components, and the `emptty` display manager.
+- `desktop_sway_packages` — binaries specific to the Sway session.
+`profile_packages` remains the shared package bucket for Void and Fedora profiles. Rocky uses
+`rocky_profile_packages` so RPM-specific names do not leak back into the other platforms; do not move
+desktop-specific Void entries through either bucket.
+The dotfile vars follow the same split: `desktop_common_dotfiles` carries mode-independent content and `desktop_minimal_dotfiles` carries Thunar, Udiskie, and MIME defaults. `desktop_void_dotfiles` remains reserved for files that need the Void runtime.
 
 ## Workstation Notes
-- `deadalus` is modeled as Windows + WSL; keep Linux dev automation on `deadalus-wsl`.
-- Native Linux workstation groups remain available for future hosts but have no current host in the main inventory.
+- `deadalus` is modeled as Windows + Fedora WSL and is the sole workstation target.
+- Fedora WSL belongs to `platform_fedora`, `workstation_dev_fedora`, and the shared WSL layer. It must not receive Flatpak or Snap runtimes.
+- Fedora WSL installs Mise from the official `jdxcode/mise` COPR and uses its pinned Temurin Java 11 JDK; update the declared Mise version deliberately.
+- Windows applications are installed manually and are not managed from the WSL profile.
+
+## Rocky Server Notes
+- DuckDNS is rendered by `profile_server` from host-local `server_duckdns_domain` and
+  `vault_duckdns_token`. Keep the rotated token in encrypted Vault or untracked local vars, never in
+  dotfiles. The private `~/duckdns/duck.sh` keeps the existing entrypoint; rendering uses `no_log`
+  and disables diffs. Provisioning does not execute the updater or change its external schedule.
+- `rocky_server` is a child of both `platform_rocky` and `server`; `prometheus` is its active target.
+- The target must already provide `server_username` with local sudo access before the profile runs.
+- The Rocky profile installs Podman and podman-compose, uses firewalld, preserves SELinux enforcement, and renders the
+  existing Nginx Proxy Manager/Gitea Compose stack with a `podman-compose-server` systemd unit. PostgreSQL and
+  Navidrome are no longer part of the desired Prometheus configuration. The role does not stop or remove legacy
+  containers, delete `/opt/postgres/data`, start the Compose stack, update DNS, or cut over traffic.
+- Firewalld enables SSH, Cockpit (`9090/tcp`), HTTP and HTTPS. Nginx Proxy Manager publishes `80/tcp` and
+  `443/tcp`; bind its administration interface only to `127.0.0.1:81` and use `npm-tunnel` from Ikaros or Nymph.
+  Nextcloud remains disabled; do not provision `/srv/nextcloud` directories.
+- `scripts/migrate_prometheus_data.sh` is the separate, source-host-run NPM/Gitea migration path. It dry-runs by
+  default and requires explicit source-stack quiescing before copying persistent Docker data with rsync.
+- Atlas-only OpenZFS, NFS, Samba, and Syncthing stay selected through Atlas host variables and must not
+  leak into `rocky_server`. Cockpit plus its Navigator and Podman extensions are selected explicitly for
+  Prometheus through its host variables.
+
+## Atlas NAS Notes
+- `atlas` is a remote Rocky Linux 9 NAS. Keep its connection, LAN, pool and mountpoint values in
+  `host_vars/atlas.yml`. Bootstrap it once with `-e atlas_connection_username=<existing-admin>`;
+  subsequent runs use the dedicated Atlas account.
+- The pool is normally pre-existing. A one-time bootstrap may create it only when `atlas_create_pool=true`
+  is explicitly supplied and `atlas_zpool_disks` contains exactly four real `/dev/disk/by-id/...` paths.
+  Never partition, force, destroy, roll back, or modify the vdev layout of an existing pool.
+- `atlas_manage_storage`, `atlas_manage_sharing`, and `atlas_manage_firewall` are enabled in Atlas host vars as
+  the declared steady state; set one false only for a deliberate suspension. `atlas_manage_media_stack` remains false
+  until the future rootful Immich stack has its required Vault inputs and target validation.
+- Atlas requires `vault_atlas_admin_password_hash` for Cockpit and, while sharing is enabled,
+  `vault_atlas_samba_password`. The future rootful media stack also requires
+  `vault_atlas_immich_db_password`. Never print these values.
+- Atlas creates the complete declared hierarchy only under the verified existing or explicitly bootstrapped pool: `archive`,
+  `services`, `services/data`, `services/data/navidrome`, `services/data/syncthing`, `media`, `media/music`,
+  `media/photobook`, `backup`, `backup/hosts`, and `backup/hosts/prometheus`. `backup` has a `500G`
+  reservation covering its descendants. `archive` is the SMB-shared raw-data namespace; container state is never beneath it.
+- The `immich` system account is fixed to UID/GID `1100`, has no login shell or `wheel` membership, and receives only
+  the `video` and `render` supplementary groups. Immich's rootful Quadlets run as `1100:1100`; Server and ML receive
+  `/dev/dri`, while the Photobook external library is read-only at `/external/photobook`.
+- Atlas applies persistent kernel network hardening: redirects and source routes are rejected, martians logged, reverse-path filtering remains loose for WireGuard, and IPv4 forwarding is disabled. SSH permits only the declared administrator using public-key authentication; root login, passwords, agent and remote forwarding
+  are disabled, while local forwarding remains available for private administrative tunnels. Photobook is exported only to the configured Aegis IP with all access squashed to UID/GID
+  `1100`. Targeted SELinux is enforced persistently; a required reboot is reported but never initiated automatically. The primary LAN interface is assigned explicitly to the managed firewalld zone, and firewall rules are applied before NFS or SMB are started; their service state and TCP listeners are then verified. SMB3 exposes `Archive` to Vault-backed authorized accounts on mandatory encrypted, signed SMB3 over TCP/445 only and admits the configured LAN without host-specific exclusions.
+- Atlas NPM and Immich share a rootful Podman network. NPM publishes HTTP/HTTPS, but its administration port remains
+  bound to `127.0.0.1:81`; do not expose it directly to the LAN or Internet.
+- `profile_backend_phase1` temporarily runs rootless Navidrome and Syncthing on Atlas until Uranus replaces
+  them. It binds only to Atlas' LAN IP, never `wg0`; Navidrome and the Syncthing GUI admit only Aegis as
+  the source-NAT gateway, while native Syncthing ports admit the configured LAN. It initializes fresh
+  state only and never migrates or deletes source application data.
+- `wireguard_overlay` manages `wg0` between Prometheus (`10.0.0.1`) and Aegis (`10.0.0.2`). It persists private
+  keys only on their respective hosts, exchanges only derived public keys through Ansible, and verifies a real peer
+  handshake. Prometheus opens `51820/udp`; Aegis is the LAN gateway. Its persistent IPv4 forwarding, narrowly scoped
+  WireGuard-to-LAN firewalld policy, and source masquerading permit Prometheus to reach LAN services without a static
+  route on the router. Prometheus includes `192.168.178.0/24` in Aegis' peer `AllowedIPs`; add the Uranus VIP there
+  when it is assigned. After a firewalld reload, restore Prometheus' rootful Podman networking with
+  `podman network reload --all` so the existing proxy stack retains container DNS.
+
+## Atlas NAS TODO
+Completed validation: the existing RAIDZ2 pool and datasets, SELinux, LAN firewall, SSH, Cockpit with
+the selected 45Drives plugins, encrypted SMB3 `Archive`, the Aegis-only NFSv4 `photobook` export, and the
+Prometheus--Aegis WireGuard gateway are operational. The gateway handshake, forwarding, source masquerading,
+and TCP reachability to Atlas were verified. Temporary Navidrome and Syncthing are available through their
+manual NPM Proxy Hosts; Syncthing uses `/data/Org` backed by the SMB-shared Archive dataset. Aegis has also
+validated NFSv4.2 read, write, delete, and `all_squash` mapping to UID/GID `1100` end-to-end. The ZFS
+snapshot timers are active and the first recursive hourly snapshot completed successfully; the first
+scheduled retention prune and monthly scrub remain runtime checks.
+
+### Priority 1 - Data protection
+- [x] Deploy Ansible-managed recursive ZFS snapshots with 24 hourly, 30 daily, 8 weekly, and 12 monthly
+  generations, plus a monthly scrub on the first Sunday at 03:00. The timers and first hourly snapshot were
+  verified on Atlas. Still observe the first scheduled retention prune and scrub; Cockpit Scheduler is for
+  visibility or manual operations only, and snapshot rollback is never automated.
+- [x] Activate and validate the encrypted offsite Borg backup to the Hetzner Storage Box. Atlas uses the
+  dedicated SSH identity, pinned ED25519 host key, Vault-backed `repokey` encryption, and a locked
+  non-login `borg` account with no sudo or supplementary groups. The initial snapshot-consistent backup,
+  Borg repository check, and temporary-directory restore completed successfully; the restored `Archive`
+  tree matched the live data, and temporary snapshots and mounts were removed. The exported recovery key
+  was copied offline. Daily backup retries and logging, 30 daily, 8 weekly and 12 monthly archives,
+  compaction, and monthly repository checks are enabled. Future runs report a ZFS-based estimated
+  percentage, and a post-exit helper handles host-namespace temporary snapshot cleanup. The active
+  run predates the new progress logging and still requires an observed final cleanup result.
+- [x] Populate `/zpool/archive` with the currently available data so offsite and offline backup tests run
+  against a representative load.
+- [ ] Run and evaluate Borg against the populated pool: duration, repository capacity, deduplication, and
+  a subsequent incremental archive must be observed before considering the offsite path fully validated.
+- [x] Add the UUID-bound offline USB backup with versioned rsync, locking, capacity checks, verification,
+  safe unmounting and a tested restore procedure; never trigger it for an arbitrary USB disk. The
+  LUKS/ext4 identities were read-only verified; the manual service and 45Drives Alerts reminder timer were
+  deployed on Atlas. Interactive LUKS unlock is part of the manual service; only the reminder is
+  scheduled for the first Saturday of each month at 10:00 Europe/Rome via the existing 45Drives
+  notifier. A manual test produced an Alerts notification, not an email. The first USB attempt failed
+  on a `security.selinux` xattr and was interrupted; the xattr filter is deployed and the temporary
+  recursive snapshot and open LUKS mapper were cleaned up. A later run reported checksum verification
+  and published the USB version, but failed while removing host-namespace ZFS snapshot mounts. Those
+  exact mounts and snapshots were cleaned up. An `ExecStopPost` helper now removes only the named
+  temporary snapshot after the backup process exits. A new full run checksum-verified and published a
+  USB version; the service ended successfully, the mapper closed, no temporary USB snapshot remained,
+  and the pool was healthy. On 2026-09-25 an independent, read-only USB restore test copied one file from
+  the published `atlas/latest` version into `/var/tmp` and matched contents, owner, mode, size, mtime and
+  POSIX ACL. The temporary copy and mount were removed, the mapper closed, and the pool remained healthy.
+- [x] Test restores independently from a ZFS snapshot, Borg, and the offline USB backup before relying on
+  any backup path. The earlier Borg temporary-directory restore passed. On 2026-09-25 a separate,
+  read-only ZFS snapshot test restored one file to `/var/tmp`, confirmed matching contents, ownership,
+  mode, mtime and ACL, then removed its temporary copy and on-demand mount. This is a file-level smoke
+  test, not full dataset recovery. An independent USB file restore passed on 2026-09-25 with matching
+  content and metadata; full disaster recovery remains a separate Priority 2 task.
+- [x] Add monitoring and alerting for pool health, scrub/resilver, SMART data, temperatures, free space,
+  snapshot/local-backup growth, Hetzner Storage Box quota, and failed maintenance or backup timers.
+  The half-hourly Atlas health monitor and systemd final-failure hooks are deployed. A live probe
+  found no issues; the service and timer succeeded, and a labelled 45Drives Alerts test notification
+  was submitted. Alerts are deduplicated; email delivery is not claimed. The Storage Box quota probe
+  runs `df -m` over the dedicated pinned-key SSH identity and does not open the Borg repository.
+  Detailed archive size and deduplication remain part of the pending Borg evaluation.
+
+### Priority 2 - NAS operability and recovery
+- [ ] Document and test disaster recovery: rebuild Atlas with Ansible, import the existing pool, restore
+  from snapshot/USB/Hetzner, preserve Vault and Borg recovery material offline, and define RPO/RTO.
+- [ ] Define a controlled Rocky kernel/OpenZFS update and reboot procedure.
+- [ ] Add the Atlas-initiated least-privilege Prometheus backup pull: Prometheus exposes only prepared
+  read-only dumps through a dedicated account and Atlas retains the private SSH key, pinned host key,
+  atomic pull, verification, retention and systemd service/timer.
+- [ ] Decide whether a common SMB/NFS namespace is required. `Archive` (SMB) and `photobook` (NFS) are
+  intentionally distinct today; only if a shared namespace is selected, finalize its UID/GID, group,
+  and POSIX ACL model and test the same files through both protocols.
+
+### Priority 3 - Service expansion
+- [ ] After data protection and recovery are validated, populate `/zpool/media/music` and validate Navidrome.
+- [ ] Design and deploy Nextcloud as another explicitly temporary Atlas service before Uranus. Give it
+  separate persistent application, database, and cache storage; keep credentials in Vault; publish it only
+  through NPM over the Prometheus--Aegis gateway; and define backup, upgrade, and eventual Uranus-migration
+  procedures before exposing user data. Do not deploy Nextcloud before the data-protection checklist is complete.
+- [ ] Keep `atlas_manage_media_stack` disabled until the future Immich deployment has validated `/dev/dri`,
+  container paths, and the required Vault database secret.
+
+### Priority 4 - Optional workflows
+- [ ] After data protection is validated, move iCloudPD photo ingestion from Aegis to Atlas as a
+  temporary service until Uranus is ready. Plan to store photos in `/zpool/archive/Pictures` and
+  persistent application/MFA state outside `Archive`; validate permissions, SELinux, backups and
+  recovery before cutover. Keep the current Aegis service and Photobook NFS export unchanged until
+  the Atlas workflow is tested, then retire them explicitly if no longer needed.
+
+## Cerberus Management Node (Deferred)
+`cerberus` is postponed until the office in the new house is physically set up. It is not an inventory
+host and this section is a design and implementation backlog, not authorization to provision it early.
+
+The planned node is a Lenovo ThinkCentre M700 Tiny with an Intel Core i3-6100T, 8 GB RAM, a 256 GB SSD,
+and native 1 Gbps Ethernet. It will connect to a multi-input KVM switch using a passive DisplayPort-to-HDMI
+cable, sharing the monitor and peripherals with Ikaros. Fedora Sericea (immutable Fedora with the Sway
+Wayland compositor) is the intended OS. Cerberus is an isolated management plane: a dedicated Toolbox
+environment will run Ansible for future `uranus` cluster provisioning. Rootless Podman will host Grafana,
+Prometheus, and Loki. The 256 GB local SSD is the hot tier retaining metrics and logs for 30 days; scheduled,
+validated exports of older historical data will use a dedicated Atlas NFS dataset as cold storage.
+
+### Implementation plan
+- [ ] Confirm the office, KVM switch, passive DisplayPort-to-HDMI path, shared monitor/peripherals, and native
+  1 Gbps Ethernet are physically operational before adding Cerberus to inventory.
+- [ ] Install and update Fedora Sericea with Sway; document the immutable-host lifecycle and keep host changes
+  declarative rather than treating the base OS as a mutable workstation.
+- [ ] Model Cerberus as its own host with independent platform, role, desktop, network, and storage inputs;
+  do not repurpose Ikaros variables or make it a Uranus cluster member.
+- [ ] Provision an isolated Toolbox-based Ansible controller with the required collections and a reproducible
+  project checkout; define its least-privilege SSH access, known-host handling, and Vault workflow without
+  storing secrets in the image or repository.
+- [ ] Define the explicit Uranus provisioning workflow from Cerberus, including inventory boundaries,
+  validation-only runs, and separate approval for any destructive cluster operation.
+- [ ] Design rootless Podman/Quadlet services for Grafana, Prometheus, and Loki, including persistent local
+  state, service ownership, LAN exposure/authentication, resource limits, updates, and backups.
+- [ ] Size and enforce a 30-day local hot-retention policy for metrics and logs on the 256 GB SSD; validate
+  actual disk growth and alert before capacity exhaustion.
+- [ ] Create and validate a dedicated Atlas NFS cold-storage dataset and least-privilege export for Cerberus;

 ## Coding Agent Notes
-- Shared agent packages live in `ai_agents_npm_packages` in `ansible/inventory/group_vars/all.yml`.
+- Shared agent definitions and lifecycle flags live in `ai_agents` in `ansible/inventory/group_vars/all.yml`.
 - Shared agent dotfiles live in `ai_agents_dotfiles`; rendered configs live in `ai_agents_templates`.
-- Desktop, native workstation, and WSL profiles consume the shared agent package list; do not duplicate package entries in profile-specific vars.
-- `dotfiles_common` copies common dotfiles plus `ai_agents_dotfiles`, then renders `ai_agents_templates`.
+- Every `ai_agents.<agent>` entry has independent `install_enabled`, `deploy_enabled`, and `uninstall_enabled` flags. Installation and removal must not both be true for the same agent; the common pre-task fails before changes when they conflict.
+- Fedora, Void desktop, and WSL workstation profiles consume the shared agent definitions; do not duplicate package entries in profile-specific vars. IBM Bob on the workstation follows its own flags.
+- `dotfiles_common` deploys `ai_agents_dotfiles` and renders `ai_agents_templates` only when deployment is enabled.
+- Removal is limited to the managed npm packages and `/usr/local/bin/bob`; never remove agent dotfiles, instructions, credentials, or user data.
 - Keep `.config/ai/` as the common instruction source; update agent-specific entrypoints to reference it rather than duplicating instruction text.

+## Aegis Fedora IoT Notes
+- `aegis` is a remote Fedora IoT Raspberry Pi 4 node. Bootstrap it once with
+  `ansible/bootstrap/aegis.bu`; the remaining configuration is applied by `profile_aegis` over SSH.
+- Fedora IoT is immutable. Do not add it to mutable Fedora package or shared dotfile roles.
+- `profile_aegis` owns the `nfs-utils` and `wireguard-tools` rpm-ostree layers and reports the required reboot
+  without initiating it. `wireguard_overlay` then configures Aegis as the WireGuard LAN gateway with persistent IPv4
+  forwarding, a scoped inter-zone policy, and source masquerading. It also owns rootful Podman Quadlets, persistent container
+  state under `/var/lib`, the Podman auto-update timer, LAN-restricted firewalld rules, and SSH hardening. Keep
+  `aegis_lan_subnet`, `aegis_adguard_web_port`, and `aegis_network_connection_uuid` host-specific;
+  SSH permits only the declared
+  key-authenticated users, never root or password authentication. Keep Apple IDs and other
+  credentials in Vault and use `no_log` for their rendering.
+- `aegis_adguard_web_port` defaults to `80`. The initial AdGuard Home wizard port `3000` is intentionally unmanaged: open and close it manually only while
+  completing initial setup. Disable the local systemd-resolved stub through `profile_aegis` before
+  AdGuard binds port 53; keep
+  `/etc/resolv.conf` linked to `/run/systemd/resolve/resolv.conf`. LAN clients may use AdGuard, but
+  Aegis must use the independent upstream DNS declared by `aegis_host_dns_servers` so Greenboot does
+  not depend on the AdGuard container during startup.
+- iCloudPD requires post-deployment interactive MFA initialization; its cookie/configuration state is
+  persisted in `/var/lib/icloudpd/config`.

-## What this repo is
-
-Ansible-driven personal infrastructure as code for Fedora desktops (`ikaros`, `nymph`), WSL development (`deadalus-wsl`), and an Ubuntu server (`prometheus`). See `AGENTS.md` for topology and `README.md` for full profile descriptions.

-
-## Architecture
-
-Configuration is composed in layers: `all → OS → profile → host`. All hosts use `ansible_connection: local`.
-
-`ansible/site.yml` is the sole orchestration entry point — keep it thin. Implementation belongs in roles under `ansible/roles/`.
-
-Variable layering:
-- `ansible/inventory/group_vars/` — OS and profile defaults
-- `ansible/inventory/host_vars/` — host-specific overrides (never put host overrides in group_vars)
-
-Dotfiles under `dotfiles/` mirror the same layer split: `common/`, `desktop/`, `server/`, `workstation/`, then per-host directories (`ikaros/`, `nymph/`).
-
-## Key conventions
-
-- FQCN for all Ansible modules.
-- Prefer declarative modules over `command`/`shell`; when shell is unavoidable, make idempotency explicit.
-- YAML: start with `---`, 2-space indent, file modes quoted as `"0644"`, booleans as booleans.
-- `no_log: true` on any task that handles secrets.
-- Do not restart `emptty` in playbook tasks on active desktop hosts — do it manually via SSH/TTY.
-
-## Void desktop package buckets (keep disjoint)
-
-- `void_packages_base` — system runtime (init, kernel, audio core, networking, firewall, hw daemons)
-- `desktop_common_packages` — WM-agnostic GUI infra (GTK theme, polkit, keyring, portals, flatpak, printing)
-- `desktop_sway_packages` / `desktop_hyprland_packages` — session-specific binaries; cross-WM packages used by both (`dunst`, `rofi`, `alacritty`) are intentionally duplicated
-- `profile_packages` — cross-distro; do not move desktop-only Void entries into it
-
-Dotfile var split follows the same logic: `desktop_common_dotfiles` (WM-agnostic), `desktop_void_dotfiles` (Void runtime — turnstile services, bash fragments).
-
-## Secrets
-
-- `secrets/vault.yml` and `secrets/vault.local.yml` are loaded conditionally if present.
-- `secrets/.vault_pass.gpg` is used automatically if present; falls back to `secrets/.vault_pass`.
-- Never print vault values; always use `no_log: true` where secrets flow through tasks.
-
-## AI agent dotfiles
-
-Shared agent instructions live in `dotfiles/common/.config/ai/`. Agent-specific entrypoints reference that path rather than duplicating content. Shared npm packages are in `ai_agents_npm_packages` in `ansible/inventory/group_vars/all.yml`.

+# Infra — Personal Infrastructure as Code
+
+> **English version:** [README.md](README.md)
+
+Questo repository contiene la configurazione **Infrastructure as Code (IaC)** utilizzata per gestire e mantenere allineate diverse macchine personali tramite **Ansible**.
+
+L'obiettivo è avere **una singola fonte di verità** per:
+
+- configurazione delle macchine
+- pacchetti installati
+- servizi di sistema
+- configurazioni utente (dotfiles)
+
+Il repository consente di gestire più sistemi operativi e profili macchina mantenendo una struttura modulare, riproducibile e idempotente.

+Il repository è diviso in due componenti principali:

+
+# Macchine gestite
+
+Il repository modella attualmente host Fedora/GNOME, una workstation Fedora WSL, un server Rocky
+Linux 9 e un NAS Rocky Linux 9. La composizione resta separata in assi indipendenti:
+
+```text
+common user environment
++ host-specific platform
++ role-specific software
++ independently selectable desktop
++ host hardware overrides
+```
+
+Matrice target:
+
+| Host         | Platform | Role                 | Desktop |
+| ------------ | -------- | -------------------- | ------- |
+| ikaros       | Fedora   | Personal workstation | GNOME   |

+
+Regola operativa:
+
+```text
+ikaros must be boring
+nymph is allowed to break
+```
+
+`ikaros` usa Fedora Workstation/GNOME come desktop personale stabile; `nymph` usa lo stesso
+target Fedora Workstation/GNOME come laptop. I gruppi legacy `void` e `desktop` restano alias di
+compatibilita per eventuali host Void futuri mentre i nuovi assi sono
+`platform_*`, `role_*` e `desktop_*`.
+
+Nota sullo stato attuale del playbook principale:
+
+- `ansible/site.yml` applica oggi in automatico Fedora/GNOME su `ikaros` e `nymph`
+- `ansible/site.yml` applica il profilo Fedora WSL alla workstation `deadalus`
+- `ansible/site.yml` applica il profilo server Rocky a `prometheus` con DNF, systemd, dotfiles server e firewalld
+- `ansible/site.yml` applica il profilo NAS Rocky su `atlas` tramite SSH remoto
+
+## Nodo pianificato e posticipato: Cerberus
+
+`cerberus` e un nodo di management **posticipato**, in attesa dell'allestimento
+fisico dell'ufficio nella nuova casa. Non e ancora presente nell'inventory e non
+esistono ruoli o playbook che lo prendano come target.
+
+L'hardware previsto e un Lenovo ThinkCentre M700 Tiny (Intel Core i3-6100T,
+8 GB di RAM e SSD da 256 GB) con Ethernet nativa a 1 Gbps. Condividera monitor
+e periferiche di Ikaros tramite uno switch KVM a ingressi multipli, usando un
+cavo passivo DisplayPort-HDMI per il collegamento video. Il sistema operativo
+previsto e Fedora Sericea, la variante Fedora immutabile con compositor Wayland
+Sway.
+
+Cerberus sara un management plane isolato: Ansible verra eseguito in un ambiente
+Toolbox dedicato per il provisioning del futuro cluster `uranus`, anziche da
+Ikaros o da un host non gestito. Lo stack di osservabilita rootless Podman
+eseguira Grafana, Prometheus e Loki. L'SSD locale sara l'hot storage, con
+metriche e log conservati per 30 giorni; esportazioni programmate trasferiranno
+i dati storici piu vecchi su un dataset Atlas montato via NFS come cold storage.
+Il piano di implementazione, con prerequisiti espliciti, e in `AGENTS.md`.
+
+## Desktop
+
+Target operativi:
+
+- `ikaros`: Fedora Workstation + GNOME, desktop personale stabile/floating.
+- `nymph`: Fedora Workstation + GNOME, laptop desktop con dotfiles desktop condivisi e GNOME lasciato al default Fedora.
+
+Il profilo Void desktop resta disponibile come modello riutilizzabile per host
+futuri e usa esclusivamente `desktop_environment: minimal`: Sway e il default,
+mentre Niri si seleziona con il gruppo `desktop_niri`. GNOME e disponibile solo
+sui target Fedora tramite `desktop_gnome`.
+
+Lo stato attuale del profilo desktop include, tra le altre cose:
+
+- dotfiles comuni e desktop
+- sessioni Sway e Niri per eventuali host Void in modalita `minimal`
+- `emptty` con default host-specific in modalita `minimal` e session file Wayland per `sway`
+- pacchetti Void Linux e servizi runit; le liste pacchetti Void desktop sono separate per criterio:
+  - `void_packages_base` per il runtime sistema (init, kernel, audio core, networking, firewall, hw daemons)
+  - `desktop_common_packages` per l'infrastruttura condivisa
+  - `desktop_minimal_packages` per applicazioni GTK e `emptty`
+  - `desktop_sway_packages` per i binari specifici della sessione Sway
+- `turnstile` per i servizi utente Void, incluso `ssh-agent`
+- `ssh-agent` con socket stabile condiviso tra shell e SSH in `~/.local/state/ssh-agent/socket`
+- Emacs usa una sola configurazione orientata a Org e authoring, condivisa da desktop Fedora/GNOME e workstation; Vim resta l'editor di sviluppo
+- `tmux` con plugin gestiti da TPM al bootstrap del profilo desktop
+- Flatpak con remoto Flathub
+- GNOME Keyring e `udiskie` nella modalita minimale
+- multi-monitor Void: sotto Sway è gestito da `kanshi`
+
+---
+
+## Workstation
+
+La workstation `deadalus` usa Fedora in WSL sulla macchina Windows omonima, senza runtime Flatpak o Snap.
+Il profilo è pensato per sviluppo e lavoro.
+
+Nel modello Ansible usato qui, un singolo inventory host puo appartenere intenzionalmente a piu gruppi e quindi ricevere piu play nello stesso run: l'associazione non e `1 host = 1 play`, ma `host + gruppi = layering finale`.
+
+Il profilo workstation e agganciato al playbook principale tramite:
+
+- layer dev Fedora
+- layer WSL dedicato per sviluppo con `systemd`
+
+Lo stato attuale del profilo workstation include:
+
+- installazione pacchetti base Fedora via dnf
+- installazione e configurazione di Docker dal repository ufficiale
+- installazione di Mise dal COPR ufficiale con JDK Eclipse Temurin Java 11 fissato
+- gestione dei dotfiles workstation e rendering dei template dev condivisi
+- preparazione di Fedora WSL con `systemd` per il toolchain di sviluppo
+- attivazione del firewall `firewalld` sui target Fedora che dichiarano regole host-specifiche
+
+Workflow WSL previsto:
+
+1. avviare Fedora WSL almeno una volta e completare la creazione dell'utente Linux
+2. installare Ansible dentro la distribuzione WSL
+3. lanciare il playbook dalla distribuzione su `deadalus` per configurare l'ambiente dev locale
+4. usare VS Code con le estensioni Remote (`WSL`, `SSH`, `Dev Containers`) dal lato Windows
+
+Le applicazioni Windows sono installate e gestite manualmente; il profilo WSL non installa componenti di remoting Python per esse.
+
+---
+
+## Server
+
+Sistema operativo:
+
+- Rocky Linux 9
+
+Configurazione:
+
+- nessun ambiente grafico
+
+Macchina:
+
+- `prometheus`
+
+Profilo orientato a servizi server e gestione di dotfiles dedicati.
+
+Lo stato attuale del profilo server include:
+
+- installazione pacchetti Rocky via DNF, EPEL e CRB
+- installazione di Podman e podman-compose
+- abilitazione dei servizi systemd dichiarati in inventory/group vars
+- copia dei dotfiles server e rendering del `docker-compose.yml` per Nginx Proxy Manager e Gitea,
+  piu l'unita `podman-compose-server` (attivazione manuale)
+- attivazione di firewalld con SSH, Cockpit (`9090/tcp`), HTTP e HTTPS abilitati
+- Syncthing escluso dal profilo server Rocky
+
+Il Compose desiderato su Prometheus non include piu Navidrome ne il database PostgreSQL obsoleto.
+Navidrome e Syncthing appartengono ad Atlas; Navidrome ufficiale usa invece SQLite. Il profilo non
+arresta o rimuove automaticamente eventuali container legacy e non elimina `/opt/postgres/data`.
+
+Nginx Proxy Manager pubblica solo `80/tcp` e `443/tcp`; la sua interfaccia di amministrazione e
+associata a `127.0.0.1:81` ed e raggiungibile da Ikaros o Nymph con l'alias Bash `npm-tunnel`.
+Nextcloud resta disabilitato e il profilo non crea directory `/srv/nextcloud`.
+
+La fase 1 su Atlas non modifica questo deployment NPM ne i suoi dati persistenti. Dopo aver attivato
+WireGuard e i servizi Atlas, configurare i proxy host NPM correnti con upstream Navidrome
+`http://10.0.0.2:4533` e upstream per la GUI Syncthing `http://10.0.0.2:8384`. Solo la GUI web di
+Syncthing usa NPM; il traffico di sincronizzazione resta sulle porte native pubblicate esplicitamente solo
+sull'indirizzo WireGuard di Atlas. Configurare l'autenticazione Syncthing e una policy di accesso NPM adeguata prima di pubblicare la GUI.
+
+### DuckDNS
+
+`profile_server` genera `~/duckdns/duck.sh` con permessi `0700`, mantenendo il percorso dello
+script e `duck.log`. Definire `server_duckdns_domain` negli host vars del server e salvare il
+**nuovo token rigenerato** in `vault_duckdns_token`, nel Vault cifrato `secrets/vault.yml`
+(`ansible-vault edit secrets/vault.yml`) oppure negli override non versionati `secrets/vault.local.yml`.
+Non committare lo script generato e non passare il token sulla riga di comando. Il rendering
+nasconde output e diff sensibili; lo script verifica TLS e passa il token a curl tramite stdin.
+Il playbook non esegue lo script e non modifica la sua schedulazione esterna.
+
+```bash
+ansible-playbook ansible/site.yml --limit prometheus --tags duckdns --check --diff
+ansible-playbook ansible/site.yml --limit prometheus --tags duckdns
+```
+
+La cancellazione dalla cronologia non revoca il token: rigenerarlo sul pannello DuckDNS.
+Dopo la bonifica, riclonare gli altri checkout senza unire nuovamente la vecchia storia;
+salvare separatamente eventuali modifiche non committate senza copiare segreti.
+
+### Migrazione dati
+
+Dopo il provisioning Rocky, eseguire `scripts/migrate_prometheus_data.sh` **sul server Ubuntu
+sorgente**. Lo script usa rsync, e in dry-run di default; richiede `--quiesce-source --execute` per
+fermare lo stack sorgente e copiare in modo consistente soltanto i dati di Nginx Proxy Manager e
+Gitea. Non sposta Navidrome o Syncthing, non avvia container, non cancella dati e non esegue il
+cutover.
+
+Utente del profilo server:
+
+- il profilo usa `server_username`, `server_user_group` e `server_user_home` definiti in `ansible/inventory/group_vars/server.yml`
+- per default `server_username` eredita `username`, ma puo essere sovrascritto per tutti gli host server via inventory oppure a runtime con extra vars
+- esempio override da CLI:
+
+```bash
+ansible-playbook ansible/site.yml --limit prometheus -e server_username=myuser
+```
+
+- se necessario puoi passare anche:
+
+```bash
+ansible-playbook ansible/site.yml --limit prometheus -e server_username=myuser -e server_user_group=mygroup -e server_user_home=/srv/myuser
+```
+
+---
+
+## NAS
+
+`atlas` è un NAS Rocky Linux 9 raggiunto via SSH. Normalmente il pool esiste già e il profilo gestisce
+solo i dataset figli. La creazione iniziale del RAIDZ2 richiede esplicitamente `atlas_create_pool=true`
+e quattro percorsi `/dev/disk/by-id/...` verificati in `atlas_zpool_disks`. Il ruolo non partiziona,
+forza, distrugge, ripristina né modifica il layout vdev di un pool esistente. I client Linux usano NFSv4,
+quelli Windows/WSL SMB; l'accesso è limitato alla LAN configurata.
+
+Per il primo avvio servono `vault_atlas_admin_password_hash`, `vault_atlas_samba_password` e
+`vault_atlas_immich_db_password`; il primo è un hash compatibile con `/etc/shadow`, non una password
+Cockpit in chiaro. Il bootstrap usa l'amministratore preesistente:
+
+```bash
+ansible-playbook ansible/site.yml --limit atlas \
+  -e atlas_connection_username=<existing-admin>
+```
+
+Le esecuzioni successive usano `atlas_admin_username`. Storage, condivisioni e firewall LAN sono
+abilitati; prima dell'applicazione verificare pool, mountpoint, subnet e zona firewalld. La creazione
+del pool è protetta da un gate esplicito e avviene solo se è assente. Atlas non fa più parte della VPN
+WireGuard: la vecchia interfaccia è stata ritirata manualmente dopo la verifica del collegamento tra
+Prometheus e Aegis. Le chiavi SSH autorizzate sono in file separati sotto
+`~/.ssh/authorized_keys.d/`. `atlas_manage_media_stack` resta disabilitato finché `/dev/dri`, percorsi
+dei container e segreto del database Immich non sono validati.
+
+Sotto `zpool` Atlas crea `archive` (SMB), `services/data` con i dataset applicativi
+`services/data/navidrome` e `services/data/syncthing`, `media`, `media/music`, `media/photobook` e
+`backup/hosts/prometheus`. Archivio e applicazioni usano `zstd`; media, Syncthing e backup host usano
+`lz4`. `backup` ha una riserva di `500G` che copre i discendenti. SELinux targeted è persistente;
+l'eventuale riavvio necessario viene segnalato, non eseguito. Atlas assegna l'interfaccia primaria
+alla zona firewalld gestita, rifiuta redirect e source route, registra i martian, mantiene il reverse-path
+filter loose e disabilita il forwarding IPv4. SSH consente soltanto l'amministratore dichiarato con
+chiave pubblica: root, password, agent forwarding e remote forwarding sono disabilitati, mentre il
+forwarding locale resta disponibile per i tunnel amministrativi. SMB3 espone `Archive` agli account
+autorizzati da Vault sulla LAN, solo su TCP/445 con cifratura e firma obbligatorie. NFSv4 espone
+soltanto `media/photobook` all'IP di Aegis su TCP/2049, con `all_squash` verso UID/GID `1100`.
+
+L'account di sistema `immich` usa UID/GID `1100`, non ha shell di login né gruppo `wheel` e riceve i
+gruppi `video` e `render`. Lo stack Immich futuro prevede Quadlet rootful per Server, ML, cache,
+PostgreSQL e NPM su una rete Podman comune. Immich gira come `1100:1100`, Server e ML ricevono
+`/dev/dri` e Photobook è montato in sola lettura su `/external/photobook`. NPM pubblica `80` e `443`;
+l'interfaccia amministrativa resta su `127.0.0.1:81`, raggiungibile via tunnel SSH.
+
+Atlas ospita temporaneamente Navidrome e Syncthing rootless fino alla sostituzione con Uranus. I
+servizi sono inizializzati **ex novo**, senza migrare lo stato precedente, rispettivamente sotto
+`/zpool/services/data/navidrome` e `/zpool/services/data/syncthing`; la musica in
+`/zpool/media/music` viene popolata separatamente. Sono vincolati all'indirizzo LAN di Atlas
+(`192.168.178.55`), mai a WireGuard. `wireguard_overlay` collega invece Prometheus (`10.0.0.1`)
+e Aegis (`10.0.0.2`): le chiavi private restano sui rispettivi host e Ansible scambia solo le pubbliche.
+Prometheus apre `51820/udp`; Aegis inoltra soltanto il traffico overlay→LAN dichiarato e applica
+source NAT, evitando interfacce VPN su Atlas/Uranus e route statiche sul router. Navidrome (`4533/tcp`)
+e la GUI Syncthing (`8384/tcp`) ammettono solo Aegis, mentre le porte native Syncthing sono limitate
+alla LAN. Dopo la verifica dei servizi, configurare manualmente i Proxy Host NPM verso
+`http://192.168.178.55:4533` e `http://192.168.178.55:8384`. Il peer Prometheus include la LAN
+negli `AllowedIPs`; aggiungere la VIP Uranus quando esisterà. Dopo il reload di firewalld, Ansible
+ricarica le reti Podman rootful di Prometheus per conservare DNS e connettività del proxy.
+
+Validare il gateway con:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit prometheus,aegis --tags wireguard --check --diff
+```
+
+La prima esecuzione reale WireGuard deve includere entrambi i peer. Se Aegis ha appena installato il
+layer `wireguard-tools`, riavviarlo manualmente e rieseguire senza `--check`: il ruolo attende un
+handshake effettivo.
+
+Gli snapshot ZFS ricorsivi coprono l'intero pool: 24 orari al minuto 05, 30 giornalieri alle 00:15,
+8 settimanali la domenica alle 01:00 e 12 mensili il primo giorno alle 02:00. La retention elimina
+solo gli snapshot con prefisso gestito `atlas-auto` e non esegue rollback. Lo scrub OpenZFS mensile è
+previsto la prima domenica alle 03:00; il timer settimanale incompatibile è disabilitato. Il primo
+snapshot orario ricorsivo è riuscito; la prima pulizia pianificata e il primo scrub schedulato
+richiedono ancora una verifica a runtime.
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags snapshots,scrub --check --diff
+```
+
+Il backup Borg cifrato usa il sub-account Hetzner `u660064-sub1`, il repository relativo `./borg-data`
+e Borg remoto 1.4 su SSH porta 23. La chiave ED25519 del server è fissata; una chiave client dedicata
+appartiene all'account `borg`, bloccato e senza login, sudo o gruppi supplementari. La chiave privata
+resta in `/etc/atlas-borg`; la passphrase proviene da `vault_atlas_borg_passphrase` ed è resa in un
+file `0600`. Solo il wrapper root crea snapshot e mount; avvia il client come `borg` con il minimo
+accesso temporaneo in lettura, senza concedergli gestione ZFS o sudo.
+
+Il backup giornaliero parte alle 04:30 con un ritardo casuale fino a 30 minuti. Crea uno snapshot ZFS
+ricorsivo temporaneo e ricostruisce tutti i dataset sotto `/zpool` in un albero di bind mount in sola
+lettura, per inserirli in un unico archivio coerente. Il wrapper smonta ricorsivamente l'albero privato;
+un helper `ExecStopPost` mirato rimuove eventuali mount dello snapshot nel namespace host e lo snapshot
+temporaneo dopo l'uscita del processo. Borg conserva 30 archivi giornalieri, 8 settimanali e 12
+mensili, poi compatta il repository. Il controllo completo di metadati e repository si svolge il 15
+di ogni mese alle 06:00. Le operazioni usano un lock comune, journal e retry systemd limitati. Le
+nuove esecuzioni riportano al massimo una riga di avanzamento al minuto: percentuale **stimata**,
+dataset, file elaborati e byte originali/compressi/deduplicati. Il denominatore è la somma dei
+`logicalreferenced` ZFS dello snapshot, non un totale Borg: può superare il 100% e non comprende
+retention, compattazione o controlli. Le righe di progresso non riportano i nomi dei file; eventuali
+warning possono farlo. Seguire il job con `sudo journalctl -fu atlas-borg-backup.service`; modifiche
+all'helper non cambiano un'esecuzione già avviata.
+
+Attivazione iniziale esplicita:
+
+1. Inserire una passphrase unica in `secrets/vault.yml` con `ansible-vault edit`.
+2. Generare e mostrare solo la chiave pubblica con
+   `ansible-playbook ansible/site.yml --limit atlas --tags borg_key`.
+3. Installarla nel sub-account Hetzner, poi applicare con
+   `ansible-playbook ansible/site.yml --limit atlas --tags packages,borg`.
+4. Copiare `secrets/recovery/atlas-borg-repokey.export` su un supporto davvero offline: la copia
+   locale ignorata da Git non è di per sé un backup offline.
+
+Il ruolo inizializza solo un repository `repokey` assente, non accetta password SSH né host key non
+fissate e non avvia manualmente il primo backup. Validazione:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags packages,borg --check --diff
+```
+
+L'attivazione iniziale è riuscita: backup e controllo del repository, restore completo in una
+directory temporanea confrontato con l'albero `Archive`, esportazione offline della chiave di recupero
+e pulizia di snapshot/mount temporanei. Il 2026-09-25 un test separato da snapshot ZFS giornaliero ha
+copiato un file di `/zpool/archive` in `/var/tmp`, verificando contenuto, proprietario, modalità,
+mtime e ACL POSIX; copia e mount temporanei sono stati rimossi senza interrompere Borg. Non è un test
+di ripristino dell'intero dataset.
+
+Il backup USB offline è distribuito come **servizio solo manuale** (`atlas_manage_usb_backup: true`):
+Ansible non formatta, sblocca, monta né avvia automaticamente il disco. Il disco esistente è stato
+verificato in sola lettura il 2026-09-23: UUID LUKS `577b3c43-ea37-4611-81a9-39d555cdfbd4`,
+UUID ext4 interno `758e2d2e-a427-4797-aad9-39c3a9f17c7e`, mapper `zpool-backup`. All'ispezione
+era montato in `/mnt/zpool-backup`; il servizio richiede invece che il mapper **non sia montato** prima
+dell'avvio. Se serve, `systemd-ask-password` chiede interattivamente la passphrase LUKS tramite
+l'agente di `systemctl start` e la passa direttamente a `cryptsetup`, senza salvarla, esporla negli
+argomenti o memorizzarla nella cache. Lo script monta il disco privatamente, crea uno snapshot ZFS
+ricorsivo, copia tutti i dataset in `atlas/snapshots/<timestamp>/` con `rsync --link-dest`, verifica
+con un dry-run basato sui checksum, aggiorna atomicamente `atlas/latest`, smonta e chiude LUKS. Un
+errore non sostituisce `latest` né cancella versioni complete precedenti. Borg e USB possono operare
+contemporaneamente su snapshot distinti, ma la lettura concorrente può ridurre il throughput.
+
+La copia USB conserva le ACL ma non gli attributi estesi generici, compreso `security.selinux`: la
+policy della destinazione deve ricreare le etichette dopo un restore. Per un percorso esplicito:
+
+```bash
+ansible-playbook ansible/site.yml --limit atlas --tags restorecon \
+  -e '{"atlas_restorecon_paths":["/zpool/archive"]}'
+```
+
+Il task accetta solo percorsi sotto la radice del pool Atlas, esegue `restorecon -RFv` solo su quelli
+indicati ed è altrimenti inattivo; non va lanciato sull'intero pool durante i run ordinari. Le vecchie
+versioni USB non vengono eliminate automaticamente senza una retention deliberata. Il controllo di
+capacità include il trasferimento stimato e una riserva libera di 10 GiB. Dopo un backup riuscito,
+scollegare fisicamente il disco per renderlo davvero offline.
+
+Validare la configurazione senza avviare il backup e, separatamente, un eventuale relabel pianificato:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags usb_backup,usb_reminder --check --diff
+ansible-playbook ansible/site.yml --limit atlas --tags restorecon --check \
+  -e '{"atlas_restorecon_paths":["/zpool/archive"]}'
+```
+
+Prima dell'avvio manuale smontare in sicurezza `/mnt/zpool-backup`, se ancora montato. Con il mapper
+chiuso, `sudo systemctl start atlas-usb-backup.service` chiede la passphrase e avvia il backup; né la
+password LUKS né un keyfile vanno in Ansible. Seguire con
+`sudo journalctl -fu atlas-usb-backup.service`. **Non esiste un timer di backup USB.** Soltanto
+`atlas-usb-reminder.timer` è schedulato il primo sabato del mese alle 10:00 `Europe/Rome`: invia un
+promemoria al notifier 45Drives Houston, senza avviare il backup. Un test manuale ha prodotto una
+notifica in 45Drives Alerts, **non un'email**; il log conferma l'invio della notifica, non la consegna
+di posta. Il primo evento pianificato era il 2026-10-03 alle 10:00 CEST. Controllare timer e risultato
+con `systemctl list-timers atlas-usb-reminder.timer` e in 45Drives Alerts.
+
+Il primo tentativo USB del 2026-09-23 fallì su `security.selinux` e, dopo l'interruzione, lasciò
+snapshot e mapper aperti. Applicato il filtro rsync, furono rimossi lo snapshot fallito, il mapper
+smontato e lo stato failed; non rimase una copia valida di quel tentativo. Un run del 2026-09-24
+pubblicò una versione verificata ma fallì nella distruzione dello snapshot a causa di mount
+`.zfs/snapshot` aperti nel namespace host. Dopo la pulizia non forzata, è stato aggiunto un helper
+`ExecStopPost` mirato e testato con uno snapshot usa-e-getta. Un run successivo del 2026-09-24 ha
+verificato i checksum, pubblicato la versione ed è terminato con successo: mapper chiuso, nessuno
+snapshot USB temporaneo e pool sano. Il 2026-09-25 un test di restore indipendente ha aperto il disco
+in sola lettura, montato ext4 con `ro,noload`, copiato un file di 5.707.945 byte da `atlas/latest` in
+una directory vuota sotto `/var/tmp` e confrontato contenuto, proprietario, modalità, dimensione,
+mtime e ACL POSIX. Il test ha rimosso copia e mount temporanei, chiuso LUKS e lasciato il pool sano
+mentre Borg continuava. È un test su file, non un esercizio completo di disaster recovery.
+
+Il monitoraggio Atlas è eseguito ogni 30 minuti da `atlas-health-monitor.timer`. Sonde in sola
+lettura controllano stato/errori del pool e dei vdev, scrub/resilver, SMART dei quattro dischi del
+pool e dell'NVMe di sistema, temperature dei dischi e CPU, spazio di sistema/pool/snapshot, crescita
+di `zpool/backup` e quota Hetzner tramite `df -m` via SSH con l'account `borg` e la chiave fissata.
+La query remota non apre il repository Borg né il suo lock. Gli alert di crescita richiedono una
+baseline di circa 24 ore. Sono controllati anche attivazione e freschezza dei timer; hook systemd
+`OnFailure` segnalano errori di snapshot, scrub, Borg, USB, promemoria e monitoraggio. Il monitor non
+riavvia Borg; avvisa solo se un run supera 14 giorni. Soglie e percorsi stabili dei dischi sono nelle
+variabili host. Gli avvisi usano 45Drives Houston con deduplicazione; **la consegna email non è stata
+verificata**. Il controllo live del 2026-09-25 non ha trovato problemi; la notifica di prova è stata
+inviata e lo Storage Box risultava occupato al 22%. Dimensione dell'archivio Borg e deduplicazione
+dettagliata richiedono ancora la fine del backup in corso.
+
+```bash
+ansible-playbook ansible/site.yml --limit atlas --tags monitoring --check --diff
+sudo /usr/local/libexec/atlas-health-monitor --dry-run
+sudo journalctl -u atlas-health-monitor.service -n 100 --no-pager
+systemctl list-timers atlas-health-monitor.timer
+```
+
+`--dry-run` non invia alert e non modifica lo stato del monitor. Un controllo reale si avvia con
+`sudo systemctl start atlas-health-monitor.service`, senza avviare servizi di backup. Per una prova
+etichettata di 45Drives Alerts usare
+`sudo /usr/local/libexec/atlas-health-monitor --test-notification`.
+
+### Timer systemd di Atlas
+
+Tutti i nove timer gestiti sono abilitati. Gli orari sono locali ad Atlas (`Europe/Rome`); Borg e
+monitoraggio aggiungono il ritardo casuale indicato. Tutti hanno `Persistent=true`: un evento perso
+viene recuperato quando il timer torna attivo.
+
+| Timer | Pianificazione (`OnCalendar`) | Azione |
+| --- | --- | --- |
+| `atlas-zfs-snapshot-hourly.timer` | `*-*-* *:05:00` — ogni ora al minuto 05 | Snapshot ricorsivo orario e retention |
+| `atlas-zfs-snapshot-daily.timer` | `*-*-* 00:15:00` — ogni giorno alle 00:15 | Snapshot ricorsivo giornaliero e retention |
+| `atlas-zfs-snapshot-weekly.timer` | `Sun *-*-* 01:00:00` — domenica alle 01:00 | Snapshot ricorsivo settimanale e retention |
+| `atlas-zfs-snapshot-monthly.timer` | `*-*-01 02:00:00` — primo giorno del mese alle 02:00 | Snapshot ricorsivo mensile e retention |
+| `zfs-scrub-monthly@zpool.timer` | `Sun *-*-01..07 03:00:00` — prima domenica alle 03:00 | Scrub ZFS |
+| `atlas-borg-backup.timer` | `*-*-* 04:30:00` — ogni giorno alle 04:30, più 0–30 min casuali | Backup cifrato offsite |
+| `atlas-borg-check.timer` | `*-*-15 06:00:00` — giorno 15 alle 06:00, più 0–30 min casuali | Controllo repository Borg |
+| `atlas-usb-reminder.timer` | `Sat *-*-01..07 10:00:00 Europe/Rome` — primo sabato alle 10:00 | Solo promemoria 45Drives Alerts |
+| `atlas-health-monitor.timer` | `*:0/30` — ogni mezz'ora, più 0–5 min casuali | Controlli di salute in sola lettura |
+
+`atlas-usb-backup.service` **non ha timer** e va avviato manualmente. Il timer del fornitore
+`zfs-scrub-weekly@zpool.timer` è disabilitato a favore dello scrub mensile. Il futuro pull del backup
+Prometheus non ha ancora un timer, perché non è implementato. Durante un backup Borg attivo,
+`systemctl list-timers` può mostrare `-` per il prossimo evento senza che il timer sia disabilitato.
+Per vedere la pianificazione corrente: `systemctl list-timers --all` su Atlas.
+
+Nextcloud è previsto come servizio temporaneo su Atlas prima di Uranus, ma solo dopo la validazione
+della protezione dei dati: richiede storage applicativo, database e cache separati, segreti Vault,
+pubblicazione solo tramite NPM e Aegis, procedure di backup, aggiornamento e migrazione. Non
+distribuirlo prima di completare la checklist di protezione dei dati.
+
+La destinazione futura per l'importazione foto iCloud è Atlas, non Aegis. Dopo la validazione dei
+backup, pianificare una migrazione esplicita di iCloudPD con foto sotto `/zpool/archive/Pictures` e
+stato applicativo/MFA fuori da `Archive`; testare permessi, SELinux, backup e restore prima del
+cutover. L'attuale iCloudPD su Aegis e l'export NFS Photobook restano configurati fino
+all'approvazione e alla verifica di questa migrazione separata. Anche il servizio Atlas sarà
+temporaneo in attesa di Uranus.
+
+Il pull dei backup di Prometheus, la valutazione delle dimensioni degli archivi Borg e i test completi
+di disaster recovery restano da fare. Il backlog prioritizzato è in `AGENTS.md`.
+

+
+# Composizione della configurazione
+
+Emacs è abilitato sui profili Fedora/GNOME e workstation; la configurazione canonica è distribuita da `dotfiles_common`, con Org in `~/Org/`, template versionati e export PDF/HTML/Markdown/DOCX/ODT. Per abilitarlo temporaneamente su un altro profilo:
+
+```bash
+ansible-playbook ansible/site.yml --limit <host> --tags emacs -e emacs_enabled=true
+```
+
+La configurazione finale di una macchina è ottenuta combinando più livelli.
+
+```text
+common configuration
++ platform configuration
++ role configuration
++ desktop configuration
++ host overrides
+```
+
+Esempi correnti:
+
+```text
+ikaros -> common + platform_fedora + role_personal_workstation + graphical_desktop + desktop_gnome + ikaros
+nymph  -> common + platform_fedora + graphical_desktop + desktop_gnome + nymph
+deadalus -> common + platform_fedora + workstation_dev_fedora + workstation_dev_wsl + deadalus
+```
+
+Questo approccio consente di:
+
+- mantenere configurazioni condivise
+- applicare override specifici per host
+- evitare duplicazioni
+- riutilizzare il profilo Void corrente su un host futuro assegnandolo a
+  `platform_void + graphical_desktop + desktop_sway`
+
+---
+
+# Ruoli Ansible
+
+I principali ruoli attualmente presenti sono:
+
+| Role                      | Descrizione                         |
+| ------------------------- | ----------------------------------- |

+| dotfiles_common           | distribuzione dotfiles comuni       |
+| dotfiles                  | distribuzione configurazioni utente |
+
+---
+
+# Stato attuale del playbook principale
+
+Il playbook `ansible/site.yml` e attualmente composto da blocchi per asse:
+
+```text
+all -> dotfiles_common
+platform_void -> packages_void + services_runit
+platform_void & graphical_desktop -> profile_desktop_common + profile_desktop_sway + profile_desktop_niri + profile_desktop_host
+platform_fedora -> packages_fedora + services_systemd
+platform_rocky -> packages_rocky + services_systemd
+wireguard_overlay -> wireguard_overlay (dopo platform_rocky)
+atlas -> profile_atlas
+role_backend_phase1 -> profile_backend_phase1 (dopo atlas)
+platform_fedora & role_personal_workstation -> profile_personal_workstation
+platform_fedora & desktop_gnome -> profile_desktop_gnome
+workstation_dev_fedora -> profile_workstation_dev_common
+workstation_dev_wsl -> profile_workstation_dev_wsl (dopo platform_fedora + workstation_dev_fedora)
+rocky_server -> dotfiles_common + profile_server (dopo platform_rocky)
+```
+
+Questo significa che, allo stato attuale:
+
+- `ikaros` riceve Fedora Workstation/GNOME come target desktop personale stabile
+- `nymph` riceve Fedora Workstation/GNOME come target laptop
+- il profilo Void resta selezionabile tramite `platform_void + graphical_desktop` per host futuri
+- `deadalus` riceve il profilo Fedora WSL tramite play dev dedicati
+- il server Rocky (`prometheus`) e gestito con pacchetti, servizi, dotfiles server e firewalld
+- il NAS Rocky (`atlas`) usa un pool ZFS gia esistente, condivisioni NFSv4/SMB limitate alla LAN e Cockpit/45Drives
+- lo stack Compose server include soltanto `gitea` e `nginx-proxy-manager`; Navidrome e Syncthing
+  della fase 1 sono Quadlet rootless su Atlas
+
+# Dotfiles
+
+La directory `dotfiles/` contiene le configurazioni utente versionate.
+
+```text
+dotfiles/
+├── common
+├── desktop
+├── server
+├── fedora
+├── workstation
+├── workstation_dev_wsl
+└── nymph
+```
+
+Le configurazioni sono applicate tramite Ansible e organizzate per livelli:
+
+| Livello | Scopo                            |
+| ------- | -------------------------------- |
+| common  | configurazioni condivise         |
+| profile | configurazioni per tipo macchina |
+| host    | override specifici               |
+
+---
+
+# Requisiti
+
+Per utilizzare il repository sono necessari:
+
+- Python 3
+- Ansible
+- `ansible-lint`
+- `yamllint`
+- `shellcheck`
+- collection definite in `ansible/collections/requirements.yml`
+- accesso locale o SSH alle macchine target, in base a come e definito l'inventory
+
+Installazione base:
+
+```bash
+python3 -m pip install ansible ansible-lint yamllint shellcheck-py
+ansible-galaxy collection install -r ansible/collections/requirements.yml
+```
+
+Gestione segreti:
+
+- il repository supporta il caricamento opzionale di `secrets/vault.yml`
+- il repository supporta anche `secrets/vault.local.yml` per override locali non versionati
+- `secrets/vault.yml.example` funge da template/esempio
+- se `secrets/vault.yml` non e presente, il playbook continua comunque senza caricare variabili locali opzionali
+- se `secrets/.vault_pass.gpg` esiste viene usato automaticamente per sbloccare i vault tramite `gpg`; in alternativa resta supportato `secrets/.vault_pass` come fallback legacy locale; se nessuno dei due file esiste Ansible richiede la password in modo interattivo
+
+---
+
+# Utilizzo
+
+Eseguire il playbook principale:
+
+```bash
+ansible-playbook ansible/site.yml
+```
+
+Allo stato attuale questo comando:
+
+- distribuisce i dotfiles comuni a tutti gli host
+- per `platform_void` applica pacchetti Void e servizi runit
+- per `platform_void + graphical_desktop` applica bootstrap desktop condiviso, sessioni Sway/Niri e override specifici per host
+- per `platform_fedora` applica pacchetti Fedora e servizi systemd a `ikaros`, `nymph` e `deadalus`
+- per `platform_fedora & role_personal_workstation` applica il layer personale a `ikaros`
+- per `platform_fedora & desktop_gnome` applica il profilo GNOME a `ikaros` e `nymph`
+- per `workstation_dev_wsl` applica i tweak WSL dopo il layer Fedora a `deadalus`, escludendo Flatpak e Snap
+- per `platform_rocky` applica pacchetti Rocky e servizi systemd ad `atlas` e `prometheus`; quindi applica il profilo NAS ad `atlas` e il profilo server a `prometheus`
+- non riavvia automaticamente il display manager
+- carica `secrets/vault.yml` solo se presente
+- carica `secrets/vault.local.yml` solo se presente, dopo `vault.yml`, cosi gli override locali hanno precedenza
+
+Per validare prima di applicare:
+
+```bash
+ansible-playbook ansible/site.yml --syntax-check
+ansible-playbook ansible/site.yml --limit ikaros,nymph --check --diff
+ansible-playbook ansible/site.yml --limit ikaros --check --diff
+ansible-playbook ansible/site.yml --limit nymph --check --diff
+ansible-playbook ansible/site.yml --limit deadalus --check --diff
+ansible-playbook ansible/site.yml --limit prometheus --check --diff
+ansible-playbook ansible/site.yml --limit atlas --check --diff
+ansible-lint ansible/site.yml
+ansible-lint ansible/roles
+yamllint ansible/
+```
+
+Per testare un override dell'utente server senza modificare l'inventory:
+
+```bash
+ansible-playbook ansible/site.yml --limit prometheus --check --diff -e server_username=myuser
+```
+
+Per validazioni piu mirate:
+
+```bash
+ansible-playbook ansible/site.yml --limit <host> --tags <tag1>,<tag2> --check --diff
+ansible-playbook ansible/site.yml --limit <host> --start-at-task "<task name>" --check --diff

+
+## Tag supportati dal playbook
+
+Per vedere l'elenco reale aggiornato dei tag disponibili:
+
+```bash
+ansible-playbook ansible/site.yml --list-tags

+
+Allo stato attuale `ansible/site.yml` espone questi tag:
+
+| Tag | Scopo | Ambito principale |
+| --- | --- | --- |
+| `always` | pre-task sempre eseguiti, inclusi caricamento vault e validazioni preliminari | common |

+
+# Bootstrap di una nuova macchina
+
+Una nuova macchina può essere inizializzata con i seguenti passaggi:
+
+```bash
+git clone <repo>
+cd <repo-dir>
+ansible-galaxy collection install -r ansible/collections/requirements.yml
+ansible-playbook ansible/site.yml
+```
+
+Dopo l'esecuzione del playbook la macchina verra configurata secondo il profilo definito e i ruoli attualmente orchestrati.
+
+Per aggiungere un nuovo host Void che riusa il profilo desktop preservato:
+
+1. aggiungere l'host a `platform_void`;
+2. aggiungerlo a `graphical_desktop`;
+3. usare Sway, oppure aggiungerlo a `desktop_niri` per selezionare Niri;
+4. lasciare eventuali dettagli hardware in `host_vars/<host>.yml`.
+
+I gruppi legacy `void` e `desktop` sono parent di compatibilita, quindi un host
+in `platform_void` e `graphical_desktop` continua a ricevere anche le variabili
+Void e desktop esistenti.
+
+Per il flusso mail desktop esiste inoltre uno script dedicato:
+
+```bash
+scripts/bootstrap_mail.sh
+```
+
+Lo script si occupa del bootstrap dei secret nel keyring, del primo sync con `mbsync` e dell'inizializzazione di `mu` usando la configurazione mail generata dai template.
+
+Se modifichi questo script, valida almeno con:
+
+```bash
+sh -n scripts/bootstrap_mail.sh
+shellcheck scripts/bootstrap_mail.sh
+```
