docs(reference-ansible): add docs/ tree and document repo, playbooks, Makefile

Addresses the WKS PoC review (Notion 2026-05-26). All docs in English. - README: purpose, docs table of contents, annotated repo tree - docs/getting_started.md: prerequisites (WKS account, OIDC, SSH, VPN) + first deploy - docs/ansible.md: playbook table, "Running Ansible", service parameters, cheatsheet - docs/secrets.md: canonical Bao login (moved out of README) + demo defaults - docs/operations.md: full Makefile reference - docs/inventories.md: repo layout, topology, standard folder structure, walkthrough - docs/testing.md: static checks, inventory resolution, smoke test / dry run - remove ARCHITECTURE.md (architecture docs live externally) Also includes the gymburgdorf inventory build-out (bookstack, homarr, opnform, send) and scripts/bao-seed.sh.

-# Architekturskizze — `demo-gymburgdorf`
-
-Diese Skizze zeigt, wie das `reference-ansible`-Repo am Beispiel der
-Inventory `demo-gymburgdorf` funktioniert: welche Hosts existieren,
-welche Rollen darauf laufen, wo welche Variablen hingehören und wie
-Secrets aus OpenBao gelookupt werden.

-  (DMZ-Modus für `reverseproxy`, Backend-Modus für `application`/`storage`).
- `backend_servers = {application, storage}` → setzt
-  `traefik_mode: backend` via group_vars.
- Service-Gruppen (`nextcloud_servers`, `garage_servers`, …) sind

-## 5. Variablen-Cheatsheet — wo gehört was hin?
-
-| Variable | Wohin in `demo-gymburgdorf/` | Warum |
-|---|---|---|
-| `vault_addr`, `vault_mount` | `group_vars/all/vault.yml` ✅ | Vault-Endpoint gilt site-weit |
-| `docker_registry_mirrors` | `group_vars/all/docker.yml` ✅ | Pulls aus Mirror auf allen Hosts |
-| `traefik_acme_*`, `traefik_use_ssl`, `traefik_cert_mode` | `group_vars/traefik_servers/traefik.yml` ✅ | Gilt für alle Traefik-Instanzen (dmz + backend) |
-| `traefik_mode: backend` | `group_vars/backend_servers/traefik.yml` ✅ | Default für app + storage |
-| `traefik_mode: dmz` | `host_vars/reverseproxy/traefik.yml` ✅ | Host-spezifischer Override |
-| `traefik_dmz_exposed_services` | **`host_vars/reverseproxy/`** | Liste, welche Backend-Services die DMZ proxyt (nur dort sinnvoll) |
-| `nextcloud_*`, `authentik_*`, `opencloud_*`, `collabora_*`, `drawio_*` | **`host_vars/application/<service>.yml`** | Service läuft genau auf `application` |
-| `garage_*` | **`host_vars/storage/garage.yml`** | Service läuft genau auf `storage` |
-| Secrets (Passwords, Tokens, Keys) | Inline-Variable mit `lookup('community.hashi_vault.hashi_vault', vault_mount + '/data/<path>', url=vault_addr)` | Single source of truth; Pattern wie bei `_acme_tsig` |
-
-## 6. Traefik-Modi (zentral für die Architektur)
-
-**`traefik_mode: dmz`** (Public-facing Reverse Proxy auf `reverseproxy`):
-
- Aggregiert Services von Backend-Servern via
-  `traefik_dmz_exposed_services` (Host-Variablen).
- Nutzt **file provider** mit `services.yml` für statisches Routing.
- Kein Docker-Socket gemountet — keine lokalen Container.
- Routet zu `backend_host` auf anderen Maschinen.
- Selektive Backend-Auswahl via `traefik_backend_servers_to_proxy`.
-
-**`traefik_mode: backend`** (Application/Storage Server):
-
- Mountet Docker-Socket (`/var/run/docker.sock`).
- Nutzt **docker provider** für Auto-Discovery lokaler Container.
- Services mit Label `traefik.enable=true` werden automatisch exponiert.
- Beide Modi unterstützen ACME (RFC2136 DNS Challenge) oder Self-Signed.
-
-## 7. Was im aktuellen `demo-gymburgdorf` noch fehlt
-
-Im Vergleich zur `vagrant`-Inventory (Referenz) fehlen für eine
-vollständige Deployment:
-
- `host_vars/application/main.yml` — Backbone-Vars für den Host
-  (FQDN-Pattern, gemeinsame Defaults).
- `host_vars/application/{nextcloud,opencloud,authentik,authentik_outpost_ldap,collabora,drawio}.yml`
-  — die service-spezifischen Konfigurationen.
- `host_vars/storage/{main.yml,garage.yml}` — Garage-Cluster-Setup.
- `host_vars/reverseproxy/<…>.yml` mit `traefik_dmz_exposed_services`
-  — sonst routet die DMZ nichts.
-
-Die `vagrant`-Inventory ist das Template: dieselbe Struktur auf
-`application`/`storage` mappen, FQDNs auf `*.gymb.souveredu.ch`
-umstellen, Secrets durch Bao-Lookups ersetzen.

 # reference-ansible

+## Purpose

+This repository is the **Ansible setup for the Digitalboard demo
+deployments** — reproducible reference tenants on which the full stack
+(identity, storage, office, forms, dashboards, …) can be set up and
+demonstrated end-to-end.

-### Secrets
-Secrets are managed using [OpenBao](https://bao.digitalboard.ch).
-The bao CLI needs to be installed. e.g `sudo pacman -S openbao python-hvac`
+It contains **no** roles of its own: all logic comes from the collection
+[`digitalboard.core`](https://git.digitalboard.ch/Digitalboard/digitalboard.core)
+(via [requirements.yml](requirements.yml)). What lives here is the
+**inventory and configuration layer** — one dedicated inventory per
+tenant under `inventories/demo-*` that wires up the roles, defines hosts
+and domains, and pulls secrets from [OpenBao](https://openbao.org/). The
+only playbook is [playbooks/site.yml](playbooks/site.yml).
+
+The repository thus serves two purposes:
+
+- **Demo operation:** deploy and keep up to date the existing demo
+  tenants (`demo-gymburgdorf`, `demo-mbazürich`, `demo-phbern`).
+- **Template:** create new tenants following the `demo-gymburgdorf`
+  pattern — see [docs/inventories.md § Walkthrough](docs/inventories.md#walkthrough-creating-a-new-demo-tenant).
+
+> **Demo-only.** All role defaults (passwords, tokens, RPC secrets) are
+> insecure and intended exclusively for demo setups. For production
+> adaptation, see [docs/secrets.md](docs/secrets.md).

-Authenticate and export token before running playbooks:
 ```bash
+make install                            # collections into ./collections/
+
+# Log in to OpenBao — in the SAME shell as the deploy.
+# Full login flow + make-bao caveat: docs/secrets.md

+
+make ping_demo                          # smoke test against all demo inventories
+make deploy_site_demo_gymburgdorf       # single demo site
+make deploy_site_demo                   # all three demo sites
+```
+
+Login details and the `make bao` caveat: [docs/secrets.md](docs/secrets.md#openbao-login).
+Prerequisites, all make targets, and the deploy flow:
+[docs/operations.md](docs/operations.md). Invoking Ansible directly
+(`--limit`, `--check`): [docs/ansible.md § Running Ansible](docs/ansible.md#running-ansible).
+
+## Available playbooks
+
+The only playbook is [playbooks/site.yml](playbooks/site.yml) — a
+sequence of plays, each applying one `digitalboard.core` role to a host
+group (base, traefik, garage, authentik, authentik_outpost_ldap,
+nextcloud, collabora, drawio, send, opnform, homarr, bookstack, …).
+Which plays take effect in an inventory is governed solely by group
+membership in `hosts.yml`. Full play table and all service parameters:
+**[docs/ansible.md](docs/ansible.md)**.

+`become: yes`. Plays whose group has no members in an inventory run as a
+**no-op**.
+
+| # | Play / role | `hosts:` | Target in `demo-gymburgdorf`? |
+| --- | --- | --- | --- |
+| 1 | `digitalboard.core.base` | `all_servers` | ✅ all 4 hosts |

+| 15 | `digitalboard.core.bookstack` | `bookstack_servers` | ✅ `application` |
+| 16 | `digitalboard.core.opencloud` | `opencloud_servers` | — no-op (no group) |
+
+> Which plays take effect for a tenant is controlled **solely through
+> group membership** in `hosts.yml`. A service becomes active as soon as
+> its `<service>_servers` group contains a host and a matching
+> `host_vars/<host>/<service>.yml` exists.
+
+## Running Ansible
+
+**Prerequisite:** collections installed (`make install`) and logged in
+to OpenBao in the **same shell** (`VAULT_TOKEN` set) — without a token,
+the `community.hashi_vault` lookups fail. Login procedure:
+[secrets.md § OpenBao login](secrets.md#openbao-login).
+Initial setup step by step: [getting_started.md](getting_started.md).
+
+### Via Makefile (recommended)
+
+```bash
+make ping_demo                          # Smoke test (ping) against all demo inventories
+make deploy_site_demo_gymburgdorf       # single demo site
+make deploy_site_demo                   # all three demo sites in sequence
+```
+
+The Make targets encapsulate the full `ansible-playbook` invocation
+including `--diff` and the macOS fork env var. All targets:
+[operations.md § Makefile reference](operations.md#makefile-reference).
+
+### Direct `ansible-playbook` invocation
+
+When you need flags that the targets do not set:
+
+```bash
+# Full deploy of an inventory
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --diff
+
+# Only one host (e.g. just the application machine)
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --limit application
+
+# Dry run without changes
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --check --diff
+```
+
+> Because service selection runs through the groups in `hosts.yml` (not
+> through tags), `--limit <host>` is the usual way to narrow down a
+> deploy. `--check` is only of limited value with the Docker Compose-based
+> roles — some tasks report "changed" because they only learn the actual
+> container state at runtime.
+
+Deploy flow and play order: [operations.md § Deploy](operations.md#deploy).
+
+## Where parameters belong
+
+| Variable group | File in `demo-gymburgdorf/` | Why |
+| --- | --- | --- |
+| `vault_addr`, `vault_mount` | `group_vars/all/vault.yml` | Bao endpoint applies site-wide |
+| `docker_registry_mirrors` | `group_vars/all/docker.yml` | Pulls from mirror on all hosts |
+| `traefik_acme_*`, `traefik_use_ssl`, `traefik_cert_mode`, `traefik_log_level` | `group_vars/traefik_servers/traefik.yml` | applies to all Traefik instances (dmz + backend) |
+| `traefik_mode: backend` | `group_vars/backend_servers/traefik.yml` | default for app + storage |
+| `traefik_mode: dmz`, `traefik_dmz_exposed_services` | `host_vars/reverseproxy/traefik.yml` | host-specific override, only meaningful there |
+| `nextcloud_*`, `authentik_*`, `collabora_*`, `drawio_*`, `send_*`, `opnform_*`, `homarr_*`, `bookstack_*` | `host_vars/application/<service>.yml` | service runs on `application` |
+| `garage_*` | `host_vars/storage/garage.yml` | service runs on `storage` |
+| Secrets (passwords, tokens, keys) | inline var with `lookup('community.hashi_vault.hashi_vault', …)` | single source of truth via Bao, see [secrets.md](secrets.md) |
+
+## Service parameters in detail
+
+Complete variable lists are in the `defaults/main.yml` of the respective
+role in `digitalboard.core`. Below are the parameters maintained in the

+| `nextcloud_ldap_enabled`, `nextcloud_ldap_config` | LDAP backend against Authentik outpost |
+| `nextcloud_apps_to_install` | app list (groupfolders, richdocuments, spreed, user_ldap, …) |

+| `drawio_authentik_forward_auth`, `_url` | access protection via Authentik ForwardAuth |
+
+### garage (S3 object store)
+
+| Variable | Purpose |

+| `garage_s3_keys` | keys + buckets + permissions (e.g. `nextcloud`) |
+
+### send / opnform / homarr / bookstack
+
+Same pattern: `<service>_domain`/`_domains` (+ `*.int.*`),
+`<service>_base_url`, admin credentials and app keys via Bao lookup,
+plus OIDC integration with Authentik (`<service>_oidc_*`: issuer, client_id,
+client_secret, admin_group). For the concrete fields, see the respective
+`host_vars/application/<service>.yml`.

+## Variable cheatsheet
+
+Short form of the location table above — "which variable goes where":
+
+- **Site-wide** → `group_vars/all/` (Bao endpoint, Docker mirror)
+- **All Traefik** → `group_vars/traefik_servers/`
+- **app + storage** → `group_vars/backend_servers/`
+- **Single host** → `host_vars/<host>/<service>.yml`
+- **Secrets** → always Bao lookup, never plaintext (see [secrets.md](secrets.md))

+# Getting Started
+
+[← Documentation index](README.md)
+
+From zero to your first deploy. This page walks through prerequisites,
+setup, and the first Ansible run. Deeper details are linked along the way.
+
+## Prerequisites
+
+### Access (to be set up out-of-band)
+
+- **WKS account with OIDC access to OpenBao.** The login runs via
+  `bao login -method=oidc -path=Digitalboard`. Without an authorized
+  account, authentication fails — and without a token there is no
+  secret lookup, hence no deploy.
+- **Bao policy / mount read.** The account needs **Read** on the
+  mount of the target inventory (e.g. `demo-gymburgdorf/data/*`). Which
+  paths an inventory reads is documented in the `host_vars/.../<service>.yml`
+  (see [secrets.md § Secret pattern](secrets.md#secret-pattern-bao-lookup)).
+- **SSH key on the target hosts.** The hosts are provisioned as `root`
+  (`ansible_user: root`, no bastion/jump host). Your own public key
+  must be placed out-of-band as `root` on the hosts.
+- **Network access (VPN).** `bao.digitalboard.ch` and the host networks
+  (`172.16.9.0/24` DMZ, `172.16.19.0/24` backend) are not publicly
+  reachable — access requires VPN/network access into the Digitalboard network.
+
+### Tools on the control node
+
+- `ansible` (Core ≥ 2.15) — `ansible --version` to check
+- `bao` CLI ([OpenBao](https://openbao.org/)) — e.g.
+  `sudo pacman -S openbao python-hvac` (Arch) or via Homebrew
+- `python-hvac` (for `community.hashi_vault` lookups)
+- On macOS: `OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES` (set in the
+  [Makefile](../Makefile)) — without this env var, Ansible forks crash
+  on the first Bao lookup, because the Objective-C runtime is not
+  fork-safe.
+
+## 1. Clone the repo and install collections
+
+```bash
+git clone https://git.digitalboard.ch/Digitalboard/reference-ansible
+cd reference-ansible
+make install         # community.hashi_vault + digitalboard.core into ./collections/
+```
+
+There is **no** `roles/` directory in the repo — all roles come from
+the `digitalboard.core` collection. See
+[inventories.md § Repo layout](inventories.md#repo-layout-and-role-origin).
+
+## 2. Log in to OpenBao
+
+The login must happen in the **same shell** in which
+`ansible-playbook` then runs — details and the `make bao` caveat in
+[secrets.md § OpenBao login](secrets.md#openbao-login):
+
+```bash
+export BAO_ADDR=https://bao.digitalboard.ch
+bao login -method=oidc -path=Digitalboard
+export VAULT_TOKEN=$(bao print token)
+```
+
+## 3. Check connectivity (smoke test)
+
+```bash
+make ping_demo       # ping module against all three demo inventories
+```
+
+If a host does not respond, it is usually due to the SSH key
+(prerequisite above) or missing network access (VPN).
+
+## 4. Run Ansible (deploy)
+
+```bash
+make deploy_site_demo_gymburgdorf       # single demo site
+```
+
+At its core, `make` only calls `ansible-playbook` — the equivalent
+direct invocation:
+
+```bash
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --diff
+```
+
+All variants (direct invocation, `--limit`, `--tags`, check mode) and
+the make targets are documented in [ansible.md § Running Ansible](ansible.md#running-ansible).
+
+## Next steps
+
+- **What happens during a deploy?** → [ansible.md § Playbook](ansible.md#playbook-siteyml)
+- **Create a new tenant** → [inventories.md § Walkthrough](inventories.md#walkthrough-creating-a-new-demo-tenant)
+- **Store secrets in Bao** → [secrets.md](secrets.md)

+**Group memberships (from [hosts.yml](../inventories/demo-gymburgdorf/hosts.yml)):**
+
+| Group | Members | Purpose |
+| --- | --- | --- |
+| `all_servers` | `reverseproxy`, `application`, `storage`, `turn` | base role for all hosts |
+| `traefik_servers` | `children: all_servers` (all 4 hosts) | Traefik everywhere; DMZ/backend via `traefik_mode` |

+
+> **Difference from the `vagrant` inventory:** `vagrant` structures
+> Traefik differently — via the children groups `traefik_servers_dmz` and
+> `traefik_servers_backend` instead of via `backend_servers` +
+> `host_vars` override. The two topologies are **structurally
+> incompatible**; a 1:1 mapping is not possible. For new tenants, therefore,
+> take `demo-gymburgdorf` as the template.
+
+## Standard folder structure of an inventory entry
+
+A fully built-out inventory follows this layout (example
+`demo-gymburgdorf`). Currently only this inventory is built out;
+`demo-mbazürich` and `demo-phbern` so far contain only `hosts.yml`.
+
+```text

+```
+
+**Conventions:**
+
+- **`hosts.yml` is the only hard required file.** Vars are
+  optional — if one is missing, the role defaults from
+  `digitalboard.core` take effect. A new inventory therefore starts minimally with
+  only `hosts.yml` (just like `demo-mbazürich`/`demo-phbern`).
+- **`group_vars/all/vault.yml`** is effectively required as soon as
+  Bao lookups are supposed to work — without `vault_mount`/`vault_addr` the
+  secret lookups fail.
+- **One file per service** under `host_vars/<host>/<service>.yml`. The
+  file name is free (Ansible loads all YAMLs in the directory); by
+  convention it is named like the role. Which variables belong where:
+  [ansible.md § Where parameters belong](ansible.md#where-parameters-belong).
+- **`main.yml` per host** is pure documentation — a comment indicating which
+  services run on the host. Carries no productive vars.
+- **`host_vars/<host>/traefik.yml`** declares via
+  `traefik_dmz_exposed_services` which local services the
+  DMZ Traefik should make reachable from outside. The DMZ reads this
+  list via `hostvars[<backend>]` and renders its routers from it. A new
+  service exposed externally = a new entry here. Mechanics:
+  [ansible.md § traefik](ansible.md#traefik).
+
+## Walkthrough: Creating a new demo tenant
+
+Recommended template: **`demo-gymburgdorf`** (not `vagrant`, because its
+group topology is incompatible).
+
+1. **Copy the inventory:**
+
+   ```bash
+   cp -r inventories/demo-gymburgdorf inventories/demo-<kunde>
+   ```
+
+2. **Adjust `hosts.yml`:** IPs, hostnames per host.
+
+3. **`group_vars/all/vault.yml`** — set `vault_mount` to the new
+   tenant mount (`demo-<kunde>`).
+
+4. **`group_vars/traefik_servers/traefik.yml`** —
+   point `traefik_acme_dns_zone` and the `acme-tsig` lookup paths to the
+   new zone / the new Bao path.
+
+5. Go through **`host_vars/application/*.yml`** and **`host_vars/storage/*.yml`**:
+   FQDNs to the new domain pattern (e.g.
+   `*.<kunde>.souveredu.ch`), Bao lookup paths to `demo-<kunde>/data/…`.
+
+6. **Prepare OpenBao** (out-of-band, not via Ansible):
+   - Create a new KV-v2 mount `demo-<kunde>`.
+   - Write secrets: `acme-tsig`, `authentik`, `nextcloud`,
+     `garage`, … — conveniently via `make seed_bao_<kunde>` (see
+     [scripts/bao-seed.sh](../scripts/bao-seed.sh) and
+     [secrets.md § Demo-Only-Defaults](secrets.md#demo-only-defaults--must-be-overridden)).
+   - Policy for the deploy token: read on `demo-<kunde>/data/*`.
+
+7. **DNS:** Create the TSIG update zone (`demo-<kunde>._acme.digitalboard.ch`) at
+   `ns1.digitalboard.ch`, CNAMEs
+   `_acme-challenge.*.<kunde>.<tld>` pointing there.
+
+8. **Makefile** — add a new target modeled on
+   `deploy_site_demo_gymburgdorf` and add it to `deploy_site_demo`;

+# Setup & operations
+
+[← Documentation index](README.md)
+
+## Prerequisites (control node)
+
+- `ansible` (Core ≥ 2.15)
+- `bao` CLI ([OpenBao](https://openbao.org/)) — e.g.
+  `sudo pacman -S openbao python-hvac` (Arch) or via Homebrew
+- `python-hvac` (for `community.hashi_vault` lookups)
+- On macOS: `OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES` (set in the
+  [Makefile](../Makefile); without this env var, Ansible forks crash
+  on the first `community.hashi_vault` lookup, because the
+  Objective-C runtime is not fork-safe)
+
+## Initial setup
+
+```bash
+git clone <repo>
+cd reference-ansible
+make install         # Galaxy + digitalboard.core into ./collections/
+```
+
+`make install` installs `community.hashi_vault` and the
+`digitalboard.core` collection (Git, see [requirements.yml](../requirements.yml))
+into `./collections/`. There is **no** `roles/` directory in the
+repo root — all roles come from the collection, see
+[inventories.md § Repo layout](inventories.md#repo-layout-and-role-origin).
+
+## Secrets (OpenBao)
+
+Before every deploy, authenticate to OpenBao in the **same shell**. The
+full login flow, the `make bao` caveat, the lookup pattern, and
+tenant isolation are documented in **[secrets.md](secrets.md)**.
+
+## Smoke test
+
+```bash
+make ping_demo       # pings all three demo inventories (ping module)
+```
+
+## Deploy
+
+```bash
+make deploy_site_demo_gymburgdorf       # single demo site
+make deploy_site_demo_mbazürich
+make deploy_site_demo_phbern
+make deploy_site_demo                   # all three in sequence
+```
+
+`--diff` is set in the Gymburgdorf target → changes are visible per task.
+The play order and which plays run as no-ops:
+see [ansible.md § Playbooks](ansible.md#playbook-siteyml).
+
+## Makefile reference
+
+The [Makefile](../Makefile) bundles setup, secret handling, and deploy.
+It defines no variables for passing in except `DRY_RUN` (for the
+`seed_bao_*` targets) — control is via the chosen target.
+
+### Exported env vars (apply to all targets)
+
+| Variable | Value | Purpose |
+| --- | --- | --- |
+| `BAO_ADDR` | `https://bao.digitalboard.ch` | OpenBao endpoint for `bao` and `community.hashi_vault` calls |
+| `OBJC_DISABLE_INITIALIZE_FORK_SAFETY` | `YES` | macOS fork safety: without this var, Ansible forks crash on the first `hashi_vault` lookup, because the Objective-C runtime is not fork-safe |
+
+> Both are set via `export` at the top of the Makefile and thus
+> inherited by every target shell process — regardless of which target runs.
+
+### Setup & secrets
+
+| Target | Effect |
+| --- | --- |
+| `make install` | `ansible-galaxy collection install -r requirements.yml -p collections` — installs `community.hashi_vault` + `digitalboard.core` into `./collections/` |
+| `make bao` | `bao login -method=oidc -path=Digitalboard role=default` + sets `VAULT_TOKEN` via `$(eval …)`. ⚠️ The token only lives **within this single `make` invocation** — see caveat below |
+| `make seed_bao_gymburgdorf` | Seed/merge OpenBao secrets for `demo-gymburgdorf` via [scripts/bao-seed.sh](../scripts/bao-seed.sh). Idempotent: existing keys remain, only missing ones are generated |
+| `make seed_bao_mbazürich` | same for `demo-mbazürich` |
+| `make seed_bao_phbern` | same for `demo-phbern` |
+
+> The `seed_bao_*` targets understand `DRY_RUN=1` — shows the diff without
+> writing: `make seed_bao_gymburgdorf DRY_RUN=1`. Requirement:
+> `bao`, `jq`, `openssl` in `$PATH` and a valid `VAULT_TOKEN`.
+
+### Smoke test & deploy
+
+| Target | Effect |
+| --- | --- |
+| `make ping_demo` | `ansible … -m ping` against all three demo inventories in sequence; failures of individual hosts do not abort (`\|\| true`) |
+| `make deploy_site_demo_gymburgdorf` | `ansible-playbook playbooks/site.yml -i …/demo-gymburgdorf/hosts.yml --diff` |
+| `make deploy_site_demo_mbazürich` | same for `demo-mbazürich` — **without** `--diff` |
+| `make deploy_site_demo_phbern` | same for `demo-phbern` — **without** `--diff` |
+| `make deploy_site_demo` | calls the three `deploy_site_demo_*` targets in sequence |
+
+> **Inconsistency:** Only the Gymburgdorf target sets `--diff`. For
+> `mbazürich` and `phbern` you do not see the task changes — if
+> needed, invoke directly with `ansible-playbook … --diff`, see
+> [ansible.md § Running Ansible](ansible.md#running-ansible).
+
+### Token caveat (`make bao`)
+
+`make bao` alone is **not** enough for a deploy: each `make` target
+runs in its own shell, the `VAULT_TOKEN` set there only lives
+during `make bao` itself and is already gone in the next `make deploy_…`.
+Two working approaches:
+
+```bash
+# Variant A — log in manually in the active shell (survives multiple make invocations)
+export BAO_ADDR=https://bao.digitalboard.ch
+bao login -method=oidc -path=Digitalboard
+export VAULT_TOKEN=$(bao print token)
+make deploy_site_demo_gymburgdorf
+
+# Variant B — chain both as ONE make invocation (token lives for the chain)
+make bao deploy_site_demo_gymburgdorf
+```
+
+Login details and the secret pattern: [secrets.md](secrets.md#openbao-login).
+
+## Known gaps and trade-offs
+
+- **`opencloud` in `demo-gymburgdorf`:** Play present, but no
+  `opencloud_servers` group — runs as a no-op. If needed, add a group +
+  `host_vars`, see [inventories.md](inventories.md#walkthrough-creating-a-new-demo-tenant).
+- **`turn` host:** defined in the DMZ, but no STUN/TURN role in
+  [playbooks/site.yml](../playbooks/site.yml) — provisioned only via `base` +
+  `traefik`.
+- **Idempotency:** Roles are Docker-Compose-based; re-runs can
+  trigger container restarts when Compose inputs change. No
+  rollback mechanism — on failure, roll back manually.
+- **TLS renewal:** handled internally by Traefik via ACME, no external
+  renew cron in the repo.
+- **CI/testing:** currently not in the repo; smoke test via `make ping_demo`.
+- **Logging:** `traefik_log_level: DEBUG` in `demo-gymburgdorf` and
+  `vagrant` (role default `INFO`) — reduce before adapting to prod.

+# Secrets & security
+
+[← Documentation index](README.md)
+
+> This repo is explicitly intended for **demo setups**. All
+> default values in the roles are insecure and are overridden in
+> `demo-*` inventories via Bao lookups or host_vars.
+
+## OpenBao login
+
+A prerequisite is a WKS account with OIDC access to OpenBao and a
+read policy on the inventory mount — see
+[getting_started.md § Vorbedingungen](getting_started.md#prerequisites).
+
+Before each deploy, authenticate in **the same shell** in which
+`ansible-playbook` then runs:
+
+```bash
+export BAO_ADDR=https://bao.digitalboard.ch
+bao login -method=oidc -path=Digitalboard
+export VAULT_TOKEN=$(bao print token)
+```
+
+> ⚠️ `make bao` alone is **not** enough — every `make` target runs in
+> a new shell, and the `VAULT_TOKEN` set there lives only during
+> `make bao` itself. Either run the three commands above manually
+> or chain `make bao deploy_site_demo_gymburgdorf` as **one** call
+> — otherwise the deploy has no token.
+
+## Secret pattern (Bao lookup)
+
+Secrets are never stored in plaintext, but read from
+OpenBao at runtime:
+
+```yaml
+# host_vars/.../<service>.yml — one lookup per service path,
+# individual keys as properties:
+_nextcloud: "{{ lookup('community.hashi_vault.hashi_vault',
+    vault_mount + '/data/nextcloud', url=vault_addr) }}"
+nextcloud_admin_password: "{{ _nextcloud.admin_password }}"
+nextcloud_postgres_password: "{{ _nextcloud.postgres_password }}"
+```
+
+- `vault_mount` and `vault_addr` come from
+  [group_vars/all/vault.yml](../inventories/demo-gymburgdorf/group_vars/all/vault.yml).
+- KV-v2 paths need an explicit `/data/` in the path — Ansible does not
+  resolve this on its own.
+- `vault_mount` is unique per inventory (`demo-gymburgdorf`,
+  `demo-phbern`, …) → tenant isolation in Bao via mount + policy.
+
+Secrets are seeded idempotently with [scripts/bao-seed.sh](../scripts/bao-seed.sh) (or
+`make seed_bao_<kunde>`): existing keys remain,
+only missing ones are generated. OIDC client secrets are kept in sync between
+`<mount>/data/authentik` and the respective service secret.
+
+## Demo-only defaults — must be overridden
+
+These defaults in `digitalboard.core` are insecure. In every
+**production-grade** deployment they must be overridden via a Bao lookup or host_var:
+
+| Variable | Default | Where to override |
+| --- | --- | --- |
+| `keycloak_admin_password` | `changeme` | host_vars `keycloak_servers` |
+| `keycloak_postgres_password` | `changeme` | same as above |
+| `authentik_secret_key` | `changeme-generate-a-random-string` | `host_vars/application/authentik.yml` |
+| `authentik_postgres_password` | `changeme` | same as above |
+| `nextcloud_admin_password` | `admin` | `host_vars/application/nextcloud.yml` |
+| `nextcloud_postgres_password` | `changeme` | same as above |
+| `nextcloud_s3_key` / `nextcloud_s3_secret` | `changeme` / `changeme` | same as above |
+| `garage_webui_password` | `admin` | `host_vars/storage/garage.yml` |
+| `garage_rpc_secret` | `0123…cdef` (64-hex constant) | same as above |
+| `garage_admin_token` | identical to `rpc_secret` | same as above |
+| `garage_metrics_token` | identical to `rpc_secret` | same as above |
+
+> **Convention:** Every value above **must** have a Bao lookup in
+> `demo-*/host_vars/.../...yml` before the
+> inventory counts as deployable.
+
+## Threat boundaries (status: demo)
+
+| Boundary | Status | Note |
+| --- | --- | --- |
+| DMZ ↔ backend (172.16.9 ↔ 172.16.19) | **plaintext HTTP** | auth bearer, OIDC code, session cookies travel unencrypted. Demo-ok; prod: mTLS or WireGuard overlay. |
+| Host firewall | **missing** | The `base` role installs no UFW/nftables. Segmentation depends on the hypervisor/VLAN. |
+| SSH | `ansible_user: root` | No bastion, no jump host. Key distribution out-of-band. |
+| Authentik SPOF | **accepted** | IdP and SP services on the same host (`application`). Authentik outage = login outage including LDAP outpost. No break-glass path. |
+| ACME TSIG key | Bao lookup | One TSIG key per demo zone (`acme_update_key_demo_gymb`), zone-isolated. Rotation manual. |
+| Backup/DR | **out-of-scope** | Garage `replication_factor: 1`, no Postgres backup job, no Bao snapshot cron. |
+
+## Add for production adaptation
+
+- Host FW (extend the `base` role or a dedicated `firewall` role).
+- mTLS or WireGuard between DMZ and backend.
+- Authentik on a separate host, with a recovery admin token.
+- Bao policies per inventory mount (read-only for the deploy token,
+  write-only for the bootstrap job).
+- Backup cron for Postgres + Garage + Bao.
+- SSH bastion + key rotation.

+# Testing
+
+[← Documentation index](README.md)
+
+> **Status:** This repo contains **no** automated test suite
+> and **no** CI pipeline. It is the inventory/configuration
+> layer — the testable logic (roles) lives in
+> [`digitalboard.core`](https://git.digitalboard.ch/Digitalboard/digitalboard.core).
+> Role tests (Molecule or similar) therefore belong in the core repo, not
+> here.
+
+What is sensibly testable here are **inventory and playbook errors
+before the actual deploy**. There are three levels for that — from fast and
+risk-free to fully against the hosts.
+
+## 1. Static checks (no host access needed)
+
+No `VAULT_TOKEN`, no network access required:
+
+```bash
+# YAML syntax of all inventory files
+yamllint inventories/
+
+# Ansible best-practice lint over the playbook
+ansible-lint playbooks/site.yml
+
+# Playbook syntax + inventory parsing (does not yet resolve Bao lookups)
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --syntax-check
+```
+
+`yamllint` and `ansible-lint` are not preconfigured in the repo —
+they run with their defaults. If project-wide rules are desired,
+a `.yamllint`/`.ansible-lint` in the repo root would be the place for it
+(see [Open items](#open-items)).
+
+## 2. Inspect inventory resolution
+
+Shows the effectively merged variables per host — useful for seeing
+precedence surprises (group_vars vs. host_vars) before the deploy.
+Bao lookups are evaluated here, so `VAULT_TOKEN` is needed (see
+[secrets.md](secrets.md#openbao-login)):
+
+```bash
+# group/host structure as a tree
+ansible-inventory -i inventories/demo-gymburgdorf/hosts.yml --graph
+
+# all vars of a host (merged)
+ansible-inventory -i inventories/demo-gymburgdorf/hosts.yml --host application
+```
+
+## 3. Smoke test & dry run (against the hosts)
+
+Requires SSH access and `VAULT_TOKEN` — for prerequisites see
+[getting_started.md](getting_started.md#prerequisites):
+
+```bash
+# reachability of all demo hosts (ping module)
+make ping_demo
+
+# dry run: shows what WOULD change, without writing
+ansible-playbook playbooks/site.yml \
+  -i inventories/demo-gymburgdorf/hosts.yml --check --diff
+```
+
+> `--check` is only of limited value with the Docker-Compose-based roles:
+> some tasks report "changed" because they only know the real
+> container state at runtime. As a plausibility check
+> (does the playbook run through, are the vars correct?) it is still
+> useful. More on the invocation variants:
+> [ansible.md § Running Ansible](ansible.md#running-ansible).
+
+## Recommended pre-deploy workflow
+
+```bash
+yamllint inventories/ && ansible-lint playbooks/site.yml      # 1. static
+ansible-playbook playbooks/site.yml -i <inv>/hosts.yml --syntax-check
+make ping_demo                                                 # 2. reachability
+ansible-playbook playbooks/site.yml -i <inv>/hosts.yml --check --diff   # 3. dry run
+# only then: real deploy
+```
+
+## Open items
+
+- **No CI** — lint/syntax checks run only manually. A Gitea/
+  CI workflow that runs the static checks from level 1 on every push
+  would be the next step.
+- **No lint configuration** — `yamllint`/`ansible-lint` run with
+  defaults; project-wide rules (`.yamllint`, `.ansible-lint`) are missing.
+- **Role tests** — belong in
+  [`digitalboard.core`](https://git.digitalboard.ch/Digitalboard/digitalboard.core),
+  not in this repo.

+# Seed OpenBao secrets for a demo inventory. Merge semantics: existing
+# keys at a given path are kept; only missing keys are generated. OIDC
+# client secrets are synced between <mount>/data/authentik and the
+# per-service secret so authentik and the service agree on the same
+# value.
+#
+# Usage:
+#   scripts/bao-seed.sh demo-gymburgdorf
+#
+# Requirements:
+#   - bao CLI in $PATH, authenticated (make bao)
+#   - jq in $PATH
+#   - openssl in $PATH
+#
+# Environment overrides:
+#   BAO_ADDR   default https://bao.digitalboard.ch
+#   DRY_RUN=1  print what would change without writing
