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).

# ADR 0008 — CLI/templating first, customer panel later
**Status:** Accepted
## Context
A customer-facing control panel (self-service create/delete/backup/restore over
Docker + ZFS) is the single largest build — realistically months. Options: adopt
and extend an existing PaaS (Coolify/CapRover/Cloudron), build a bespoke panel
up front, or ship internal CLI tooling first and defer the UI.
## Decision
Build **provisioning as an internal CLI / templating tool first**
(`control-panel/`). The customer-facing web panel comes **later**, as a wrapper
over the same, proven CLI operations.
## Consequences
- ✅ Lowest initial risk; the provisioning logic (ZFS + DB + compose + routing)
is validated end-to-end before any UI investment.
- ✅ The CLI doubles as the automation surface the future panel and CI call into
— no throwaway work.
- ✅ Keeps early focus on correctness of isolation/backup rather than UX.
- ❌ No customer self-service until Phase 8; provisioning is operator-driven in
the meantime.
- ↔️ Adopting an existing PaaS remains an option for the panel layer if building
it proves too costly; the CLI would still own the ZFS/backup specifics.
