Merge pull request 'route-proxy README: the node that runs a proxy carries public-acme (hq #258)' (#208) from docs/route-proxy-carries-public-acme into main

The same split lost them the other way round: the merge base held both changes, each branch had reset
the other's files, and the three-way merge kept neither. Both halves of hq ADR 0161 are on main again
with this.

+# dhcpcd
+
+The uplink seat's module for a machine whose own network is dhcpcd's (novox/hq ADR 0117). It
+asks two things of dhcpcd, and nothing else: leave the resolver file to the mesh, and leave the
+private network's interface alone. It never declares an interface, an address, a route, a
+wireless network or its credentials — the link dhcpcd keeps is the only channel the mesh reaches
+the machine over.
+
+## What it writes
+
+Two lines into `/etc/dhcpcd.conf`, as the mesh's marked region (`into: block`) — dhcpcd reads no
+drop-in directory, so the mesh writes into its one file rather than over it (ADR 0102):
+
+- `nohook resolv.conf` — dhcpcd's resolv.conf hook rewrites `/etc/resolv.conf` on every lease it
+  takes or renews, which would silently replace the resolver `resolv-conf` names.
+- `denyinterfaces mesh0` — dhcpcd never asks for a lease on the private network's interface, and
+  never takes it down. dhcpcd leaves a point-to-point interface alone by default; this says so
+  rather than relying on it.
+
+**At the start of the file** (`at: start`). Both are global options, and dhcpcd reads every line
+after an `interface` or `ssid` line as that interface's own. A configured machine's file ends in
+exactly such a block (the interface, its static address), so appended at the end these two would
+quietly apply to one interface only.
+
+## Why it declares no service
+
+dhcpcd is the machine's, not the mesh's. The mesh never starts, stops or enables it: stopping it
+drops the address the machine is reached at, and a module unassigned by mistake must not be able
+to do that. And there is nothing to reload it with — `dhcpcd.service` reports `CanReload=no`, and
+a restart drops the lease. So the two lines take effect at **dhcpcd's next start**.
+
+On an adopted machine that is normally no gap: the predecessor wrote the same `nohook` line, and
+it is already in force. **On a machine that was not adopted, it is one:** until dhcpcd next
+starts (a reboot, or the operator restarting it in a window of their choosing), a lease renewal
+still rewrites `/etc/resolv.conf`, and `resolv-conf` puts it back at the next push. Assign this
+module before `resolv-conf` on such a machine, and restart dhcpcd once, by hand, when losing the
+link for a moment is acceptable.
+
+## One manager per machine
+
+It claims `the-uplink`: a machine runs one network manager, and assigning a second module that
+claims the seat is refused. Assigning this one to a machine whose network is NetworkManager's
+installs the package and writes the two lines, and starts nothing.

+// ---- MQTT ----
+
+// Home Assistant's MQTT integration, pointed at the broker the mesh bound — `mqtt-topic`.
+//
+// **Why a step.** Home Assistant keeps its broker, login and password in its MQTT config entry
+// (`.storage/core.config_entries`), not in a file the mesh could fill with `${bound:mqtt-topic:at}`.
+// So this reads the binding and the pair credential and makes the entry say the same thing, through
+// the MQTT integration's own reconfigure flow — the flow its "Reconfigure" button runs, which tests
+// the connection itself and saves nothing it could not connect with.
+//
+// **Only the connection, and only when it differs.** Broker, port, username, password. The protocol
+// version, client id, keepalive, TLS choices and discovery options the entry holds are sent back
+// exactly as Home Assistant pre-filled them. Whether the password already matches cannot be read
+// back (Home Assistant never shows a stored password), so the step keeps a digest of what it last
+// wrote: equal broker/port/username and an equal digest is "already as the mesh says".
+//
+// **Nothing loses its connection without someone seeing it.** Before Home Assistant is touched the
+// broker itself is asked whether it takes the delivered login (the provisioner creates it within
+// seconds of the grant): if not, nothing is written and the step fails saying why, and Home

+// Home Assistant's Sonarr, Radarr and Lidarr integrations, pointed at the apps the mesh bound —
+// `sonarr-api`, `radarr-api`, `lidarr-api` (their providers: mesh-catalog #156).
+//
+// **What Home Assistant lets anyone change, and what it does not.** Each integration keeps a URL and
+// an API key in its config entry. None of the three has a reconfigure flow: Home Assistant changes
+// them only through the flow its UI runs —
+//   - a **user flow** makes a new entry (validated against the app);
+//   - a **reauth flow**, which Home Assistant starts by itself when the app refuses the key it holds,
+//     takes a new key (Sonarr) or a new URL and key (Radarr, Lidarr);
+//   - anything else — the URL of a working entry — only by removing the integration and adding it
+//     again, which throws away its entities' names, areas and history links. **This step never
+//     removes an entry.**
+// So, per app:
+//   1. The bound key is tried against the bound app first. Refused, nothing is written: until the
+//      operator accepts the app's own key for this pair, the mesh delivers a value it minted, which
+//      no Servarr app takes (novox/hq ADR 0092) — the failure names the `secret accept` that fixes it.
+//   2. No entry: one is made through the user flow.
+//   3. A reauth flow Home Assistant started for the entry: finished with the bound key (and URL,
+//      where the integration's reauth asks for one).
+//   4. An entry whose URL (read from the device the integration registered, `configuration_url`)
+//      is the bound one and which is loaded: already as the mesh says. The key needs no digest here:
+//      a Servarr app has one key, so an entry loaded against the app holds the key the app took.
+//   5. A working entry at a different URL that reaches **the same app** — the same process, by the
+//      app's own status (start time, data folder, version) — is left as it is and said: ace's entries
+//      say `127.0.0.1:<port>` and the binding says `ace.internal:<port>`, one Sonarr either way.
+//   6. Anything else is refused, loudly, with what the operator can do; nothing is removed.

+// What the `influxdb-api` provision means in InfluxDB: one v1-compatibility authorization per
+// consumer, in the org this module serves, under the username and password the mesh gave both ends,
+// allowed exactly the access the consumer contributed. The provisioner (provisioner/index.ts) is the
+// sdk harness calling these; they are here, apart from it, so they can be exercised against a fake
+// InfluxDB without a broker or a contributions file.
+//
+// **Why a v1 authorization and not a v2 API token.** The mesh mints the consumer's password and
+// hands it to both ends (novox/hq ADR 0048); the provider sets it, and never hands one back. An
+// InfluxDB 2.x API token is generated by the server — `POST /api/v2/authorizations` ignores a token
+// the caller sends — so a token could only ever be the operator's to accept, one per pair, by hand.
+// A v1 authorization is a username and a password the caller chooses (8–72 characters; the mesh
+// mints 40), stored hashed, and it reads and writes through InfluxQL (`/query`) and line protocol
+// (`/write`), which every bucket answers under its own name as a database (InfluxDB maps each
+// bucket to a database of the same name by itself). That is what grafana's InfluxDB data source
+// speaks, and what Node-RED's influxdb nodes speak in their 1.x mode — so the mesh can make every
+// consumer's credential, rotate it and withdraw it, with no person in the loop.
+//
+// **What a consumer contributes.** `access`: "read" (the default), "write" or "read-write".
+// `buckets`: the buckets it may use, by name. A reader that names none may read every bucket of the
+// org — a dashboard is pointed at data, it does not own it. A writer must name its buckets: writing
+// everywhere, the org's system buckets included, is never what a consumer means. A named bucket
+// that does not exist is created, keeping its data for ever; the mesh never deletes a bucket.
+//
+// **Only what the mesh made is touched.** An authorization this module creates is named with the
+// mesh's identity prefix and its description starts with MARK. One with the same username that
+// lacks the mark is somebody else's: it is refused, never adopted, never updated, never deleted.

+// What the `oidc-client` provision means in Keycloak: one confidential OpenID Connect client per
+// consumer, in the realm this module serves, under the name and secret the mesh gave both ends.
+// The provisioner (provisioner/index.ts) is the sdk harness calling these; they are here, apart from
+// it, so they can be exercised against a fake admin API without a broker or a contributions file.
+//
+// **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
+// consumer names it as its client id through `${bound:oidc-client:as}` — and mints the secret, which
+// 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.
