Merge pull request 'mosquitto, influxdb: the provisioner sees its grants where the mesh writes them' (#182) from fix/a-provisioner-sees-its-grants-where-the-mesh-writes-them into main

The received grants file names each pair secret by its HOST path. A sidecar
that mounts the placed grants directory at another path inside its
container sees mesh.json and not the secrets beside it — mosquitto's
provisioner reported ENOENT for a file that was there, and nodered's mqtt
step failed against a login that was never created. Mounted at its own
path now, as postgres does.

+// 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.

+
+The mesh's tools, on the machine a person sits at, served by a module the mesh assigned there
+(novox/hq [ADR 0152](https://git.novox.be/novox/hq), design 34).
+
+Assign it to a machine and an agent on that machine has the mesh's tools at
+`http://127.0.0.1:<port>/mcp` — MCP over HTTP, `initialize`, `tools/list`, `tools/call`. A person at
+a terminal reaches the same endpoint with `mesh tools --console http://127.0.0.1:<port>` and
+`mesh call <module>.<tool> --console …`, with no credential of their own: the console holds it.
+
+## What it is
+
+The tool runtime's own client, `mesh serve`, started by the mesh on the credential it sealed to the
+machine for `<node>.mesh-console`. The manifest says three things nothing else in the catalogue says
+together:
+
+- `invokes: ["*"]` — it calls every tool on the mesh, and the bus grants exactly that publish side;
+- a listener `from: machine` — loopback only, and the filter opens nothing for it;
+- no `emits`, no `consumes`, no `tools` — nothing on the bus can address it.
+
+**Loopback is the authority boundary.** Whoever can connect is on the machine, and whoever is on the
+machine is the account that owns the mesh there (ADR 0034, ADR 0144). There is no token and no login,
+and `mesh serve` refuses to bind anything but a loopback address.
+
+## What it lists
+
+What the running modules answer: every tool runtime serves a `tools` verb for its module, and the
+console asks the catalogue which modules the mesh holds and each module what it serves. A module that
+did not answer — not assigned, not up, or built before the runtime answered `tools` — is named in the
+list's `_meta.notAnswering` and can still be called by `<module>.<tool>`.
+
+The mesh's own verbs (`status`, `push`, `assign`) are the `mesh-controller` seat's tools under
+ADR 0132 and are not served on the bus yet; they appear here when they are.
+
+## Port
+
+The manifest declares port 4270 and the mesh assigns the machine port as it does for any listener;
+the console binds `127.0.0.1:${port:4270}`. `node show <machine>` says which port a machine was given.

+// Node-RED's MQTT broker config node, pointed at the broker the mesh bound — `mqtt-topic`.
+//
+// **Why a step.** Node-RED keeps a broker as a config node in its flows (`flows.json`) and the login
+// and password in its encrypted credentials file, both of them Node-RED's to write. So this reads the
+// binding and the pair credential and makes the broker node say the same thing through Node-RED's
+// admin API — `GET /flows`, then `POST /flows` with the changed node and its `credentials`, deployed
+// as "nodes" so only what changed restarts — with the module's own `api-token`.
+//
+// **Which broker nodes are the mesh's.** Never guessed: a flow may talk to a broker that has nothing
+// to do with this mesh. The step owns the node it creates itself (id `mesh-mqtt-topic`, "mesh:
+// mqtt-topic") and the ones an assignment names in settings (`mqtt.brokers`: node ids — how ace's
+// existing broker node, which every one of its MQTT flows uses, is handed over). With none named and
+// none made yet, it makes one, so a fresh Node-RED has a broker the flows can pick.
+//
+// **Only the connection, and only when it differs.** Host, port, TLS off (the broker serves plain
+// MQTT), login, password. Every other field of the node — client id, keepalive, birth/close/will
+// messages — is left as it is. Node-RED never hands a stored password back, so the step keeps a
+// digest of what it last wrote: equal host/port/login and an equal digest is "already as the mesh
+// says".
+//
+// **Nothing loses its connection without someone seeing it.** The broker is asked first whether it
+// takes the delivered login; if not, nothing is written and the step fails saying why.
+//
+// Pure logic over two seams (Node-RED, the broker), tested against fakes (test/mqtt.test.ts).
