Issue every node's memberships when it is composed, so a module taken in with a new state is not refused it (issue 249 met again, issue 1945)

Release 6 removed the push (788fb681), and with it the only writer of the
memberships on ASSIGNMENTS. A module taken in since kept the membership the
old push last issued: mesh-delivery-gate, taken in with the state
"conditions" at 20:33 on 2026-10-25, was granted its bucket on the bus and
refused it by novox's tool runner every second, which keeps a module to its
membership (node-tools internal/bus/state.go issuedState).

A node's composition pass now issues the membership of each module assigned
to it, from the same records the grants are composed from, with the node's
private-network addresses and received contributions, before its
compositions are written. Only one that differs from the one last issued is
published, and only over that one (issues 930, 934). The memberships' stream,
every declared bucket and log are asserted first; the root-free judgement
runs only when a held seat promises a verified sender.

NATS-native piece moved (research 072, 03-domains, mesh-grants): the
membership is issued again by the take-in's pass, from the grants' records,
the step before mesh-grants takes both over.

-**A route is a provision** (issue 774, research 072 row 34; the operator, 2026-10-31: "there is only 1 path, the other
-is simply deprecated/invalid"). A module that must be reachable declares `requires: ["route"]` and contributes the
-name it wants and the port it listens on; this module provides `route`. The controller composes each consumer's plan,
-and the seat `mesh-provisioner` keeps it in its state `plans`: the plan's entry for the route names this proxy as
-its provider and carries what the consumer contributes, composed (its names joined to the node's domains, its
-endpoint's port, its policy), and where the consumer's machine is on the private network, as one opaque payload
-(`contributed`) the seat never reads. The proxy follows the plans on the bus, reads each contribution with its own
-contract (below), and forwards by the `Host` header of each request to `http://<at>:<port>`, or over loopback for a
-consumer on its own machine.
+**A route is a grant.** A module that must be reachable declares `requires: ["route"]` and
+contributes the name it wants and the port it listens on; this module provides `route`, receives
+every consumer that asked as a file, and forwards by the `Host` header of each request to
+`http://<at>:<port>` — where `at` is where the mesh says that consumer's machine is (empty means
+this machine, reached over loopback).
 
-## Its contract: a package of its own
-
-**route-proxy defines its own contract, and other modules use it** (the operator, 2026-10-31). It is the Go module
-`git.novox.be/novox/mesh-controller/modules/route-proxy/contract`, in `contract/` here with its own `go.mod`, standard
-library only, released by tags `modules/route-proxy/contract/vX.Y.Z`, the way mesh-sdk is released (`go/vX.Y.Z`); this
-module depends on it by its version like any other. It holds:
-
-- **the route a consumer asks** (`Request`, read strictly by `DecodeRequest`: no field it does not name, a name of
-  either kind, a port where the rule forwards, http or https, a positive body limit, a secret's file never a
-  credential) and its JSON schema (`route.schema.json`, `Schema`), the form of a manifest's `contributes.route`;
-- **the events this proxy says** on `mesh.mod.route-proxy.event.<type>`: `route.served` and `route.withdrawn` as the
-  names it serves change, `route.refused` with why for a route a plan gives it and it does not serve (`Event`);
-- **what it keeps on the bus**, its states `routes` and `unrouted`, their keys and records (`Route`, `Unrouted`,
-  `Other`, `Key`, `Split`);
-- **its tools' names and arguments** (`ToolRoutes`, `ToolRoute`, `ToolUnrouted`, `RoutesArgs`, `RouteArgs`).
-
-The controller does not write the proxy's configuration. It composes the facts into the plans and the proxy turns them
-into whatever it runs. That boundary is why swapping this proxy for another costs nothing to the modules that publish
-through it. **There is no received file and no second source:** a route no plan names is not served, and a module
-declaring `receives.route` is refused by the catalogue check (mesh-catalog `checks/credentialform`), but for the
-migration scaffolding still listed there.
+The control plane does not write the proxy's configuration. It delivers the facts — the
+contributions file at `receives.route` — and the proxy turns them into whatever it runs. That
+boundary is why swapping this proxy for another costs nothing to the modules that publish through

-## What it says on the bus, and its tools (issue 774)
-
-The proxy keeps two states, announced readable (`conn.Keeps`, novox/hq ADR 0495), each keyed `<node>.<name>`:
-
-| state | one key per | holds | written when |
-|---|---|---|---|
-| `routes` | served name | the rules it is served by (path, module, node, target, refusal, redirect, authentication); its certificate (authority, issuer, not-after, last renewal, outcome, or why it failed); the last upstream answer (status, time, error, path) | a route arrives, changes or leaves; an authority stores a certificate; a handshake fails to find one or hands out one not yet recorded; an upstream answer differs from the last one written, or the same one is a minute old |
-| `unrouted` | name answered "no route for", in a request or a TLS handshake, under a domain the proxy serves | when it was last asked, how often since the start, whether it is an internal-only name asked from outside; never who asked (the journal keeps that, for fail2ban) | first asked, at most five new names a minute, then at most once a minute; deleted when the name is served; kept a week. Every other refusal is only counted, in one key per proxy (`<node>._other`: the last minute's count and the total), written once a minute. A refused write is dropped, never retried |
-
-Nothing is written on a timer. The provider helper's binary serves the module's tools from those states, one call each:
-`route_proxy_routes` (every served name with its target, certificate expiry and last answer), `route_proxy_route`
-(one name in full, or that it is not served and when it was last asked for) and `route_proxy_unrouted` (the names
-refused, newest first).
