 ## ADR-2: A status web service of the standard library, bound to the internal address
 
-Status: Accepted; amended by ADR-7
+Status: Accepted
 
 Context: The router has no way to see its state without a shell. A check from the protected
 network, by a person or by a monitor, needs a page or an endpoint. The router is an
 internet-facing host, so what the service shows and where it listens matter.
 
 Decision: The `vpn-router-web` unit runs one Python script that uses only the standard library, in
-the way of a small test server. It binds to the address of the internal interface and to
-`web.port`, on by default at 8080. `/` is for people, in plain text for `curl` and `wget` and as
-a Tailwind CSS page for a browser, and `/status` is the same status as JSON. It shows the
-state of the services, the package version and the state of the site-to-site, road-warrior and
-WireGuard features, and nothing from the configuration. `vpn-router-setup` resolves the
-interface address, writes it with the port and the features to `/run/vpn-router/web.json`,
-opens the port on the internal interface in UFW and restarts the service, so the service does

 Consequences: Nothing outside the internal network can reach it, since it listens on the internal
-address only and the firewall opens the port on the internal interface only. It has no
-authentication, which is acceptable because it is read only and shows no configuration. It runs
-as root, because `swanctl` and `wg` need it, with `NoNewPrivileges`, `ProtectSystem=strict`,
-`ProtectHome` and `PrivateTmp`. The Tailwind style comes from a CDN, so a browser on a network

 ## ADR-3: /config is authenticated with a short-lived JWT signed with a shared secret
 
-Status: Accepted; amended by ADR-7 and ADR-8
+Status: Accepted
 
-Context: A client such as manage-ui needs the configuration and the resolved state of the

 Decision: `/config` needs a JWT in an `Authorization: Bearer` header. The service verifies HS256
 tokens with `hmac` and `hashlib`, with the secret `web.jwt_secret`, and accepts no other
 algorithm, because verifying RS256 or ES256 needs a library outside the standard library. The
 token must carry `exp`, not more than ten minutes ahead, so that the client makes a fresh token for

 ## ADR-4: Users are kept in a local OpenLDAP directory

 Context: OpenVPN needs user accounts with passwords, and the users are meant to cover every P2S
-system of the router. The options weighed were an external OIDC provider (Entra ID, Keycloak)
-with openvpn-auth-oauth2, an OIDC server embedded on the router, a file of password hashes, and
-OpenLDAP on the router. OIDC for OpenVPN needs a browser on the client and a program from outside

+## ADR-9: The Router Manager is a separate package with a small Python server
+
+Status: Accepted
+
+Context: The router needs a web application to manage it, which may run on the router or on
+another Linux system. The router's web service needs a token signed with `web.jwt_secret` for
+`/config` and `/users` and sends no CORS headers, so a browser cannot call it with the secret
+kept away from the page.
+
+Decision: `vpn-router-manager` is a Debian package of its own, built in the repository
+`linux-cloud-router-manager`. A React and MUI application in the style of manage-ui is built
+with Vite when the package is built and shipped as static files. A Python server, using the
+Ubuntu packages `python3-jwt` and `python3-requests`, serves them and passes every `/api/<path>`
+call to the router's `/<path>`, signing a short-lived token with the router's secret; it holds
+no logic of the router's own. It reads its settings from `/etc/vpn-router-manager/manager.json`
+at each request; on the router the settings not given come from `vpn-router.json`, and it
+listens on the internal address like the status web service, with the same discovery thread.
+`vpn-router-setup` opens the manager's port on the internal interface while the manager is
+installed, so the firewall stays in one place. The manager asks for no authentication.
+
+Consequences: The router needs no Node.js; the package needs only `python3` and packages of the
+Ubuntu archive. The secret never reaches the browser. The application checks the shape of every
+answer of the router. Anyone who reaches the manager's port manages the router, so on another
+system it listens on `127.0.0.1` unless told otherwise. The router's firewall depends on whether
+the manager is installed, and a changed manager port needs `vpn-router-setup` to run again.
+
+## ADR-10: Users and their certificates do not depend on a P2S system being enabled
+
+Status: Accepted
+
+Context: Users are prepared before a P2S system is switched on, and the Router Manager manages
+them on any configured router, with or without one.
+
+Decision: Once a platform is chosen, `vpn-router-setup` always provisions the user directory in
+slapd and the CA with its CRL; the server certificate follows once `wan.local_fqdn` is set.
+`/users` and `vpn-router-user` rely only on the directory and the CA. Only the OpenVPN client
+profile needs OpenVPN to be enabled.
+
+Consequences: slapd always holds the directory and the CA always exists on a configured router,
+even when no P2S system uses them. An operator who wants a CA of their own must place it before
+choosing the platform.
