Wire consumer layer: the client plugin's apply mounts `ctx.connection` (shared api client + current-page loopback state + single-consumer stream-loop starter); the export face carries the wire contract types, the `AbstractApiClient` seam, and the loop's sink/config types. The real browser carrier uses HTTP POST for unary and respond operations and opens one downlink-only WebSocket each for `events.mux` and `events.host`; the fixture and in-process carriers continue to satisfy the same two-stream abstraction. Loopback hostname classification stays package-internal: the `/api` Host fence and WebSocket upgrades use it directly, while other client plugins consume the derived `ctx.connection.isLoopback` state. The node half's `/api` route pins the privileged method set (`host.pickDirectory`, `host.openPath`, and the whole configuration plane — `settings.describe`, `settings.openDocument`, `settings.update`, `settings.replace`, `settings.mutate`, `credentials.describe`, `credentials.set`, and `credentials.unset`; reads and native actions included, since describing returns the exposed configuration, opening acts on the Host desktop, and probing an arbitrary reference reports where a credential comes from) to loopback by passing the trust fence with an empty trust list — a declared `trustedHosts` authority reaches every other method, while these stay loopback-local until a real authentication layer exists. The platform subclasses (WebApiClient/FixtureApiClient), the ConnectionController loop, and the fixture data source are package-internal apply selects and drives them; tests reach them via src. The downlink boundary is documented in the [WebSocket downlink carrier Agent Note](../../../.agents/notes/implemented/architecture/2026-08-04-websocket-downlink-carrier.md); the protocol contract is api-contracts v3 §3.

`/api/events.mux` and `/api/events.host` each accept a WebSocket upgrade and send only the corresponding `ServerRequest` text messages to the browser; the client sends no application data over these sockets. If either socket ends, the current connection generation fails and rebuilds both streams; readiness still requires both sockets to be open and the `host.describe` HTTP call to succeed. Host teardown terminates both sockets, aborts their sources, and waits for source cleanup before returning. Ordinary network GETs to these paths return 426 with no SSE fallback; `toFetchHandler`'s SSE codec serves only the isomorphic in-process carrier.
## Keyless fixture
Any `fixture` query parameter selects the in-memory carrier. `fixture=empty` starts with no Workspace or Session; `fixturePrompt=reject` rejects prompts before acceptance; `fixtureAttach=fail` publishes a Session but rejects its Workspace attachment; `fixtureSessionCreate=drop-response` publishes and frames a Session before dropping the create response; and `fixtureFrames=workspace-first` reverses the default session-first create-frame order. Workspace creation by name/path and caller-preallocated SessionIds remain deterministic enough for assembled Web tests to reconcile list and frame arrival. Fixture content search preserves the production-facing `unicode61`-style case, diacritic, and token-phrase behavior and returns a match-centered snippet of at most 120 Unicode code points.
## Model Experience
None, as the wire consumer layer moves already-composed messages between browser and host; nothing here reaches a model request.
