feat(steps): cross-tier channels — a client's fetch onto its own route, queue jobs onto consumers, bus and socket events onto handlers
- resolution/tier-synthesizer.ts: http-client (literal fetch/axios/ky/got/$fetch paths, axios.create baseURL instances, template holes as :params, base-URL holes by a two-segment tail; unique match only), queue-job (BullMQ/Bull add ↔ @Process/@Processor, WorkerHost process, new Worker, queue.process), event-bus (EventEmitter2 emit ↔ @OnEvent with globs; socket emit ↔ @SubscribeMessage / socket.on both ways with tier); channel, tier, callee, registeredAt on every edge; generic transport events never pair; test and generated files never sources; registered before the emitter pass
- steps.ts: crossing() reads tier/channel before languages; an endpoint reached across a tier is a bridge box and a boundary like a screen (through=1 enters it); a channel's call is not also an effect; sites read as written; a Next 'use server' action is a crossing by its directive (when.ts directive); a function-valued constant handler (asyncHandler(...)) is a route root and borrows the file-scope calls and refs within its lines
- express.ts: app.use('/prefix', router) mounts composed onto route names in postExtract (nested, by import or require); chained router.route('/x').get(h).put(h2) extracted, across lines
- frameworks/package-deps.ts: dependencies read from workspace package.json files too (Express, React, Expo Router, NestJS detect)
- routing manifest names constant handlers; e2e/ is a test directory; explore's Flow section labels the new channels
- tests: ui-steps-cross-tier (monorepo fixture: Next client + Express/Nest API), servers test updated for the queue landing
- docs: CHANGELOG, spec §3.13 cross-tier paragraph, CLAUDE.md, callback-edge-synthesis.md, plan P3 built

*
|

* A web app is two programs that talk over a wire the graph cannot see: the
|
||||
* page calls `fetch('/api/users', { method: 'POST' })` and the API's
|
||||
* `app.post('/api/users', createUser)` answers; a service puts `'welcome'` on
|
||||
* the `email` queue and a `@Process('welcome')` method picks it up; a
|
||||
* gateway's `this.server.emit('message')` lands in the component that wrote
|
||||
* `socket.on('message', …)`. Each hop is a string on both sides, which is the
|
||||
* evidence that lets a synthesizer close it — exactly as the RN event channel
|
||||
* pairs `sendEvent(withName: "x")` with `addListener('x')`.
|
||||
*
|
||||
* Three channels, one scan:
|
||||
*
|
||||
* 1. **`http-client`** — a literal path in a client call (`fetch`, `axios.post`,
|
||||
* `ky`, `got`, `$fetch`, `useFetch`, `useSWR`, or a project instance made by
|
||||
* `axios.create(…)` / `ky.extend(…)`) → the ONE route node `METHOD path` it
|
||||
* denotes. Template holes match a `:param`; a hole in front of the path
|
||||
* (`${API_URL}/users`) matches a route by its tail; a variable url, a path
|
||||
* no route serves, or a path two routes serve alike produce nothing.
|
||||
* Edge: enclosing function → route, `tier: 'client→server'`.
|
||||
* 2. **`queue-job`** — `queue.add('job', …)` where the queue is named (`new
|
||||
* Queue('email')`, `@InjectQueue('email')`) → the `@Process('job')` method
|
||||
* of the `@Processor('email')` class, a WorkerHost's `process`, a
|
||||
* `new Worker('email', handler)`, or Bull's `queue.process('job', handler)`.
|
||||
* 3. **`event-bus`** — `eventEmitter.emit('user.created')` → `@OnEvent('user.created')`
|
||||
* (globs honoured); and sockets in both directions: a client's
|
||||
* `socket.emit('x')` → the server's `@SubscribeMessage('x')` / `socket.on('x')`
|
||||
* (`tier: 'client→server'`), the server's `server.emit('x')` → the client's
|
||||
* `socket.on('x', …)` (`tier: 'server→client'`). The in-process
|
||||
* `.on('x', fn)` ↔ `.emit('x')` pairing stays the emitter pass's.
|
||||
*
|
||||
* Every edge is `kind: 'calls'`, `provenance: 'heuristic'`, and carries
|
||||
* `synthesizedBy`, `channel` (`http` | `queue` | `event` | `socket`), the
|
||||
* `tier` when the direction is known, the `event` / `queue` / `method` /
|
||||
* `href` it was paired on, and `registeredAt` — the route registration, the
|
||||
* decorator, the `.on` — so a reader can check the pairing. Fan-out is capped
|
||||
* per event as the emitter pass caps it; an HTTP pairing needs no cap because
|
||||
* it is exact. Test suites and generated files are never sources: a supertest
|
||||
* call is the test's story, and forty of them would make the route a hub.
