Bart Van Geyt 9f819df4d9 Phase 0: architecture docs, ADRs, and repo scaffold
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).

# heleosv2 — Multi-Tenant Web Hosting Platform
A rebuild of a small web-hosting business on modern, isolation-first
infrastructure: **container-per-customer + ZFS-dataset-per-customer**, with
repeatable CLI-driven provisioning and clean per-customer backup/restore.
> **Core philosophy — the customer is the boundary.** Isolation (containers),
> backup (ZFS), and restore all line up on the same boundary, so a compromised
> or broken site is contained and restorable without touching neighbours.
## Status
Phase 0 — writing the design documents before any platform code. See
[`docs/00-roadmap.md`](docs/00-roadmap.md).
## Repository layout
This monorepo groups four logical areas whose contents have different
lifecycles (see [`docs/07-repo-layout-gitops.md`](docs/07-repo-layout-gitops.md)):
| Path | Purpose |
|-------------------|---------------------------------------------------------------------|
| `docs/` | Architecture, ADRs, runbooks, conventions. |
| `platform-infra/` | Ansible + base compose for host, Traefik, MariaDB, Forgejo, monitoring. |
| `site-templates/` | Dockerfiles for standard images + compose templates per site profile. |
| `deployments/` | Rendered per-customer configs (GitOps state). **No plaintext secrets.** |
| `control-panel/` | Provisioning CLI now; customer-facing panel later. |
## Key decisions
- **Single bare-metal host**, Docker Compose per customer, no orchestrator.
- **Shared MariaDB** (per-site DB + least-privilege user).
- **Decoupled backups:** web files via ZFS snapshot/`send`; DB via
automysqlbackup + rsync; logs via Loki.
- **Lightweight DevOps:** Forgejo + built-in registry + Trivy.
- **CLI-first** provisioning; web panel deferred until the platform is proven.
The full approved architecture plan lives at
[`docs/architecture-plan.md`](docs/architecture-plan.md).
