No definition names this installation

keycloak, minio and n8n are told their names from their route bindings; mailu takes its domain, site
name, website and proxy address as settings and its front's name from its route, and the provisioner
reads the domain from the merged config; builder and route-proxy package the controller from the git
seat; the applications built outside the mesh say so per container; matrix says which of the world's
servers it means; the site module is named website, and the why prose no longer names a name (novox/hq
ADR 0155, issues 122 and 134). module check passes over all 77.

+// **The client id and the secret are the mesh's, not Keycloak's (novox/hq ADR 0048).** The mesh
+// derives the consumer's identity (`as`, e.g. `mesh_ace_grafana`) and hands it to both ends — the

+// this sets as the client's secret. Keycloak generates neither.
+//
+// **Where the consumer's browser comes back to is the consumer's to say.** Its contribution carries
+// `callback` (a path, e.g. `/login/generic_oauth`) and the `label`/`endpoint` of the endpoint it is
+// reached on; the mesh composes that endpoint's names into `name` (public) and `internal-name`
+// (private network) exactly as it does for a route (novox/hq ADR 0056, 0138), so the redirect URI
+// registered here is built from the same names the proxy serves the consumer under.
+//
+// **Only what the mesh made is touched.** A client this module creates carries the attribute
+// `mesh.provisioned=true`, and its id starts with the mesh's own prefix. A client with the same id
+// that lacks the mark is somebody else's: it is refused, never adopted, never updated, never deleted.

+# mailu
+
+Mail — Mailu, with its provisioner (the `smtp` provision) and tools, on the tool runtime.
+
+## Settings
+
+A definition names no mesh (novox/hq ADR 0112, ADR 0155), so the values that are this
+installation's are settings on the assignment, `settings set mailu <file>`:
+
+```json
+{"domain": "…", "sitename": "…", "website": "https://…", "proxy-address": "…"}
+```
+
+`domain` is the mail domain (also the provisioner's, for a consumer's address); `sitename` and
+`website` are shown by the web front; `proxy-address` is what `REAL_IP_FROM` trusts a real-IP
+header from — the address the proxy forwards with. The front's own hostname is the name of its
+`web` route, told to it by the mesh.
