Add zfs_pool_mode: file|single|mirror.
- file (default): loopback disk image at zfs_pool_file_path — real ZFS with
no spare disk, ideal for a cost-optimized test VM; wipes nothing.
- single/mirror: whole spare disk(s); mirror for production redundancy.
Guard/probe now loops over zfs_pool_disks. Update group_vars, README (modes,
prerequisites, safety), and CLAUDE.md current-focus note.

The six.moves ModuleNotFoundError comes from version-skewed duplicate
Ansible installs; recommend a single pipx install in prerequisites.

The playbook runs everything via become(root); note that -K
(--ask-become-pass) is required unless the target user has passwordless
sudo. Replace the misleading --check first-run hint with --syntax-check.

Running the playbook from /mnt/c in WSL makes Ansible ignore ansible.cfg
(world-writable dir), losing the inventory. Document the fix (copy to WSL
home, or export ANSIBLE_CONFIG) plus the inventory/syntax-check reminders.

Implements the two decoupled backup streams from docs/06 as an idempotent
Ansible role wired into the host playbook:
- Files: sanoid takes/prunes ZFS snapshots per policy (sanoid_datasets) on
its packaged timer; syncoid replicates offsite (heleos-zfs-offsite),
enabled only when zfs_offsite_target is set.
- DB: heleos-db-backup (nightly systemd timer) walks the deployments dir and
dumps each DB-backed site via `docker exec mariadb-dump` into
db-backups/<customer>/<site>/{daily,weekly,monthly} with rotation
(automysqlbackup-style, adapted for the containerized DB; MYSQL_PWD keeps
the password out of the process list). heleos-db-offsite rsyncs offsite
when db_offsite_target is set.
Streams and schedules are configured in group_vars/all.yml; offsite is
opt-in via the two target vars. Updates doc 06 (implementation note), the
ansible README, and CLAUDE.md status. YAML + templates validated by render.

Idempotent host configuration targeting Ubuntu 24.04 with ZFS on a
dedicated second disk. Role-based platform-infra/ansible:
- base: apt packages, timezone, unattended security upgrades.
- zfs: install ZFS, create pool on a dedicated disk (guarded against
wiping a non-empty disk), create platform datasets + customers parent
per docs/03; docker dataset mounted at /var/lib/docker.
- docker: Docker Engine + Compose plugin, daemon.json written before first
start so the native zfs storage driver initializes on the ZFS data-root;
per-site network address pool preconfigured.
- firewall: nftables inbound default-deny in a dedicated table that never
flushes Docker's rules; container outbound SMTP blocked via a DOCKER-USER
jump applied by a systemd oneshot.
- ssh_hardening: key-first SSH with an anti-lockout assertion, config
validation gate, and the sftponly group for Phase 4 SFTP accounts.
Includes ansible.cfg, requirements.yml, inventory example, group_vars with
safety notes, and a run guide. Real inventory (hosts.yml) is git-ignored.
