+- 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
- Replace every Atlas `CHANGEME` value, provide the required Vault variables and validate the first
-  remote bootstrap on the real Rocky Linux 9 host. Enable `atlas_manage_storage` first and
-  `atlas_manage_firewall` only after confirming the pool, mountpoints, LAN subnet and firewalld zone.
- Validate the complete baseline on the target: OpenZFS kmod loading, existing pool import, dataset
-  mounts, SSH reconnect, Cockpit and all selected 45Drives plugins, NFSv4, SMB and Syncthing.
- Finalize dataset properties and the shared UID/GID, group and POSIX ACL model; test the same files
-  through both NFS and SMB before considering multiprotocol access complete.
- Add Ansible-managed ZFS snapshot retention and scrub timers. Use Cockpit Scheduler for visibility
-  or manual operations, not as the only source of configuration, and never automate snapshot rollback.
- Manage the Syncthing star topology, device IDs, folders, folder modes, ignore rules and protected GUI
-  or API access for the selected clients.
- Add Tailscale or WireGuard and corresponding LAN/VPN-only firewalld rules before enabling remote
-  services; never expose SSH, Cockpit, NFS, SMB or Syncthing through public port forwarding.
- Add the least-privilege Prometheus backup flow: remote dump generation, dedicated SSH identity,
-  pinned host key, atomic pull, verification, retention and an Atlas systemd service/timer.
- Add the encrypted offsite backup with Borg to a Hetzner Storage Box: use a dedicated SSH identity,
-  pin the host key, keep Borg repository credentials and encryption material in Vault, use
-  snapshot-consistent sources, and manage retries, logging, pruning, repository checks and restores.
- Add the UUID-bound offline USB backup with versioned rsync, locking, capacity checks, verification,
+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.
+- [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 relying on the offline USB test.
+- [ ] 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.
- Add monitoring and alerting for pool health, scrub/resilver, SMART data, temperatures, free space and
-  failed backup timers, plus a controlled Rocky kernel/OpenZFS update and reboot procedure.
- Document and test disaster recovery: rebuild Atlas with Ansible, import the existing pool, restore

+  any backup path.
+- [ ] Add monitoring and alerting for pool health, scrub/resilver, SMART data, temperatures, free space,
+  snapshot/backup capacity growth, and failed maintenance or backup timers.
+
+### 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.
- Optionally design iCloud photo ingestion as a separate workflow after the storage and backup layers
-  are validated; do not make it a dependency of the Atlas baseline.
+- [ ] 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
+- [ ] Optionally design iCloud photo ingestion and an Aegis persistent NFS mount as a separate workflow
+  after the storage and backup layers are validated; do not make either a dependency of the Atlas
+  baseline.
+
+## 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;
+  do not use a broad existing share or couple it to unrelated Atlas application state.
+- [ ] Implement scheduled, idempotent exports of data older than 30 days to the Atlas NFS cold tier, with
+  locking, capacity checks, integrity verification, retention rules, failure monitoring, and a tested restore.
+- [ ] Validate management-plane recovery: rebuild Cerberus, restore observability history from Atlas, and
+  confirm that Uranus provisioning can resume without depending on unreproducible local state.

+Redis, PostgreSQL e NPM condividono una rete Podman. Immich viene eseguito come `1100:1100`; Server e
+ML ricevono `/dev/dri` e Photobook e montato in sola lettura su `/external/photobook`. NPM pubblica `80` e
+`443`, mentre l'amministrazione resta vincolata a `127.0.0.1:81` per l'accesso tramite tunnel SSH.
+
+La fase 1 e limitata ai Quadlet utente rootless di Navidrome e Syncthing su Atlas. E abilitata nella
+configurazione host di Atlas e puo essere impostata a `false` solo per una sospensione intenzionale. Navidrome ufficiale `0.63.2` usa il database SQLite sotto `/data` e
+non supporta `ND_DATABASE_URL` ne un backend PostgreSQL esterno. Il servizio obsoleto `navidromedb`
+e quindi rimosso da Prometheus invece di essere replicato su Atlas. Il ruolo deriva i percorsi dal
+pool `zpool`, montato in `/zpool`: musica in sola lettura da `/zpool/media/music`, stato
+applicativo Navidrome e `navidrome.db` in `/zpool/archive/app_data/navidrome` e dati Syncthing in
+`/zpool/archive/app_data/syncthing`. `profile_atlas` crea questi dataset quando
+`atlas_manage_storage` e attivo; il ruolo backend verifica i mountpoint esatti prima di avviare i
+container. Il ruolo backend non crea mai il pool. Il ruolo separato `wireguard_overlay`
+gestisce `wg0` tra Prometheus (`10.0.0.1`) e Atlas (`10.0.0.2`), genera una sola volta le chiavi
+private sui rispettivi host e scambia tramite Ansible soltanto quelle pubbliche. Solo Prometheus apre
+pubblicamente `51820/udp`. Le porte backend sono ammesse esclusivamente nella zona firewalld WireGuard.
+
+`backend_phase1_start_services` resta falso durante il trasferimento dello stato applicativo, quindi
+la prima esecuzione reale del backend genera i Quadlet senza creare un database Atlas vuoto. Dopo aver
+arrestato Navidrome su Prometheus, copiare l'intera directory `/opt/navidrome/data/` in
+`/zpool/archive/app_data/navidrome/`, preservando `navidrome.db` e gli eventuali file SQLite laterali.
+Impostare quindi questa variabile a vero e rieseguire il ruolo per abilitare e avviare Navidrome e
+Syncthing. Il playbook non copia e non elimina mai i dati applicativi.
+
+Validare e generare i servizi Atlas con:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags storage

+
+Per il cutover, arrestare il vecchio Navidrome prima di copiare la sua directory dati, verificare
+l'ownership dell'account `admin` su Atlas e confermare la presenza del database SQLite copiato prima
+di impostare `backend_phase1_start_services: true` in `host_vars/atlas.yml`. Conservare i dati sorgente
+e il container legacy `navidromedb` fermo finche Navidrome su Atlas e una prova di restore non sono
+stati validati.
+
+Restano da completare retention delle snapshot, topologia Syncthing, validazione WireGuard/firewall,
+pull di backup da Prometheus, backup cifrati con Borg su una Hetzner Storage Box, backup USB,
+monitoraggio e test di disaster recovery. Il backlog operativo dettagliato e in `AGENTS.md`.

+## NAS
+
+`atlas` is a Rocky Linux 9 NAS reached through SSH. Normally its pool already exists and the profile
+only manages child datasets. A one-time RAIDZ2 bootstrap is available only with explicit confirmation
+(`atlas_create_pool=true`) and exactly four verified `/dev/disk/by-id/...` paths in `atlas_zpool_disks`.
+It never partitions, forces, destroys, rolls back, or changes the vdev layout of an existing pool. Linux
+clients use NFSv4 and Windows/WSL clients use SMB; both are restricted to the configured LAN.
+
+For the first run, provide `vault_atlas_admin_password_hash`, `vault_atlas_samba_password`, and
+`vault_atlas_immich_db_password`. Bootstrap the host through its
+existing administrator. The explicit pool gate is safe to repeat: the role creates the RAIDZ2 pool only when
+it is absent. Atlas no longer participates in the WireGuard overlay; its old interface is retired manually only after
+Prometheus and Aegis have completed the replacement handshake.
+
+`vault_atlas_admin_password_hash` must be an `/etc/shadow`-compatible hash, not a clear-text
+Cockpit password. Subsequent runs use `atlas_admin_username`. Atlas declares storage, sharing, and its
+LAN firewall rules enabled. Before the first apply, check the existing pool and mountpoints, LAN subnet,
+and active firewalld zone. `atlas_manage_media_stack` remains disabled until `/dev/dri`, the container
+paths, and the Immich database secret are validated. Atlas reads its declared SSH public keys from
+separate files below `~/.ssh/authorized_keys.d/`.
+
+With storage management enabled, Atlas creates the complete dataset hierarchy below the existing or
+explicitly bootstrapped `zpool`: SMB-shared `archive`, private `services/data` with separate
+`services/data/navidrome` and `services/data/syncthing` application datasets, `media`, `media/music`,
+`media/photobook`, and `backup/hosts/prometheus`. Application/archive datasets use `zstd`, while media,
+Syncthing, and host-backup datasets use `lz4`; `backup` has a `500G` reservation covering its descendants.
+Atlas enforces targeted SELinux persistently and reports, without initiating, any reboot required to activate it. It assigns its primary LAN interface explicitly to the managed firewalld zone and 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. SMB3 exposes `Archive` only to the configured Vault-backed
+Samba accounts on encrypted, signed SMB3 over TCP/445 only and admits the configured LAN without host-specific
+exclusions. NFSv4 exports only `media/photobook` to the configured Aegis IP over TCP/2049, using
+`all_squash` with anonymous UID/GID `1100`.
+
+The `immich` system account is fixed to UID/GID `1100`, has no login shell or `wheel` membership, and
+receives `video` and `render` access. The rootful Immich Server, ML, Redis-compatible cache, PostgreSQL,
+and NPM Quadlets share one Podman network. Immich runs as `1100:1100`; Server and ML receive `/dev/dri`,
+and Photobook is mounted read-only at `/external/photobook`. NPM publishes ports `80` and `443`; its
+administration interface remains restricted to `127.0.0.1:81` for SSH-tunnel access.
+
+Atlas temporarily hosts rootless Navidrome and Syncthing until Uranus replaces them. They bind only to
+Atlas' LAN address (`192.168.178.55`); WireGuard remains exclusively between Prometheus (`10.0.0.1`)
+and Aegis (`10.0.0.2`). Their state is initialized ex novo in `/zpool/services/data/navidrome` and
+`/zpool/services/data/syncthing`; no source application state is migrated. The music library at
+`/zpool/media/music` is populated separately.
+
+The separate `wireguard_overlay` role manages `wg0` between Prometheus (`10.0.0.1`) and Aegis
+(`10.0.0.2`), generating private keys once on their respective hosts and exchanging only public keys
+through Ansible. Prometheus alone opens `51820/udp`. Aegis forwards only the declared overlay-to-LAN
+traffic and source-NATs it, so Atlas and future Uranus nodes require neither a VPN interface nor a router
+static route. Atlas permits Navidrome (`4533/tcp`) and the Syncthing GUI (`8384/tcp`) only from Aegis;
+Syncthing native ports are limited to the LAN. Configure NPM manually with
+`http://192.168.178.55:4533` and `http://192.168.178.55:8384` after the services are healthy.
+Prometheus' peer includes the LAN subnet in `AllowedIPs`; add the Uranus VIP there when it exists.
+When the WireGuard zone is created, Ansible reloads firewalld and immediately reloads Prometheus'
+rootful Podman networks so the existing proxy stack retains container DNS and connectivity.
+
+Validate the gateway with:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit prometheus,aegis --tags wireguard --check --diff
+```
+
+The first real WireGuard run must include both peers. If Fedora IoT has just layered `wireguard-tools`,
+reboot Aegis manually and rerun the command without `--check`; the role then waits for a real peer
+handshake.
+
+Atlas declares recursive, systemd-timed ZFS snapshots for the complete pool hierarchy: 24 hourly
+snapshots at minute 05, 30 daily snapshots at 00:15, 8 weekly snapshots on Sunday at 01:00, and 12
+monthly snapshots on the first day at 02:00. The retention helper prunes only snapshots carrying its
+managed `atlas-auto` prefix and never rolls back a dataset. The OpenZFS monthly scrub timer is scheduled
+for the first Sunday at 03:00; the conflicting weekly scrub timer is disabled explicitly. The first recursive
+hourly snapshot completed successfully on Atlas; retention pruning and the first scheduled scrub still await
+live runtime evidence. Validate this layer independently with:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags snapshots,scrub --check --diff
+```
+
+Atlas also declares an encrypted Borg backup to the dedicated Hetzner Storage Box sub-account
+`u660064-sub1`. The repository is the sub-account-relative `./borg-data` path and uses the explicitly
+selected remote Borg 1.4 binary over SSH port 23. The ED25519 server key is pinned; a dedicated client
+key is generated for the locked, non-login `borg` system account, and its private half never leaves
+`/etc/atlas-borg`. The account has no sudo or supplementary groups and owns only its SSH identity,
+passphrase, cache, and Borg state. Borg receives its passphrase through a mode `0600` file rendered from
+`vault_atlas_borg_passphrase`.
+
+The daily backup starts at 04:30 with up to 30 minutes of randomized delay. It creates a temporary,
+recursive ZFS snapshot and reconstructs every dataset below `/zpool` as a read-only bind-mounted tree,
+so parent and child datasets enter one consistent Borg archive. Cleanup always removes the temporary
+mounts and managed snapshot. Only the root wrapper performs snapshot and mount operations; it launches
+the Borg client as `borg` with temporary read-search capability and no ZFS, sudo, or pool-management
+privileges. Borg retains 30 daily, 8 weekly, and 12 monthly archives, then compacts the standard
+read-write repository. A full metadata and repository check runs as `borg` on the fifteenth day of each
+month at 06:00. Both operations use a common lock, journal logging, and bounded systemd retries.
+New backup runs also log the create phase and a compact progress line at most once per minute: dataset,
+files processed, and original/compressed/deduplicated bytes. Progress lines omit individual filenames
+and a percentage, since Borg does not know the total in advance; warnings may still name affected files.
+Follow the current run with
+`sudo journalctl -fu atlas-borg-backup.service` on Atlas; changes to the helper do not alter a run
+already in progress.
+
+Initial activation remains explicit:
+
+1. Add a strong unique `vault_atlas_borg_passphrase` with `ansible-vault edit secrets/vault.yml`.
+2. Generate and display only the dedicated public key with
+   `ansible-playbook ansible/site.yml --limit atlas --tags borg_key`.
+3. Install that public key in the Hetzner sub-account, then apply with
+   `ansible-playbook ansible/site.yml --limit atlas --tags packages,borg`.
+4. Copy the ignored `secrets/recovery/atlas-borg-repokey.export` file to genuinely offline storage.
+   The controller-side copy is not an offline backup by itself.
+
+The role initializes only the missing `repokey` repository and never accepts an unpinned host key or
+password authentication. It does not start the first backup manually. Validate the rendered state with:
+
+```bash
+ANSIBLE_LOCAL_TEMP=/tmp/ansible-local \
+ansible-playbook ansible/site.yml --limit atlas --tags packages,borg --check --diff
+```
+
+Atlas runtime activation is complete: the initial backup and repository check succeeded, a full restore
+to a temporary directory was validated against the live `Archive` tree, the recovery-key export was copied
+to offline storage, and the temporary snapshot and bind mounts were cleaned up.
+
+A temporary Nextcloud deployment on Atlas is also planned before Uranus: it requires separately
+declared persistent application, database, and cache storage, Vault-backed credentials, NPM-only
+publishing through Aegis, and defined backup, upgrade, and eventual migration procedures. Do not deploy
+it before the data-protection checklist is complete.
+
+Prometheus backup pulls, USB backup, monitoring, and disaster-recovery tests remain follow-up work. The
+prioritized operational backlog is kept in `AGENTS.md`.
