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.

Adopt a two-level ownership model: a customer owns many sites, with
isolation/containers/DB/backup at the site level and grouping (one SFTP
login, recursive backup, billing, bulk delete) at the customer level.
- 03-naming-conventions: rewritten for customer/site ids and slug =
<customer>-<site>; nested ZFS, per-customer SFTP chroot, deployments
mirror the nesting.
- Propagated paths through docs 01, 04, 05, 06, 07 and deployments/README.
- ADR 0005 retitled/updated to per-site datasets nested under customer.
- architecture-plan.md: note pointing to doc 03 as authoritative on naming.
Clarifies subdomains: same-app subdomains are aliases on one site; a
separate-app subdomain is its own isolated site under the same customer.

Establish the design foundation for the heleosv2 multi-tenant hosting
platform before any implementation code:
- Monorepo skeleton: docs/, platform-infra/, site-templates/,
deployments/, control-panel/ with orientation READMEs.
- docs/: roadmap index, architecture + threat model, naming conventions,
site profiles, provisioning workflow, backup & DR runbook, repo/GitOps
layout, and the approved architecture plan.
- docs/adr/: 9 ADRs recording the rationale for single-host Compose,
Traefik edge, nginx+fpm split, shared MariaDB, ZFS-per-customer,
decoupled backup streams, Forgejo, CLI-first, and SFTP-only.
- Secrets hygiene: .gitignore (only *.enc.* committed) and .gitattributes
(LF for scripts/Dockerfiles/YAML run on the Linux host).
