retaining declared protocol methods including __aenter__ and __aexit__. Keep the
filtering limited to metadata that cannot be passed to parameter_shape() and

The public entry point is create_http_client, but everything behind it was named "rest": the ably.pubsub.rest package, AblyRest, and the RestClient prototype. Rename that surface to "http" so the names a caller reads match the name they call. The transport package already holding ably.pubsub.http — Http, HttpUtils and PaginatedResult — moves to ably.pubsub.request to free the name, which also describes it better: it models individual requests, not the client. - ably/pubsub/rest/ -> ably/pubsub/http/, with rest.py -> http.py - AblyRest -> AblyHttp, RestAnnotations -> HttpAnnotations, RestChannels -> HttpChannels - the exported prototypes RestClient and RealtimeClient become PubSubHttpClient and PubSubRealtimeClient - test/ably/rest/ -> test/ably/http/, rest*_test.py -> http*_test.py, TestRest* -> TestHttp* unasync's rename list, mocked-path replacements and test directories follow the move, so the generated synchronous flavour lands at ably.pubsub.sync.http. The spec-defined options rest_host and idempotent_rest_publishing keep their names, as does "REST" where it refers to the Ably API rather than to a symbol.

In `@ably/pubsub/prototypes.py`:
- Line 34: Add a read-only http property typed as Http to the PubSubHttpClient
protocol, and import Http under the appropriate type-checking imports so
create_http_client() consumers can access client.http without type errors.
In `@ably/pubsub/request/http.py`:
- Line 185: Update the timeout selection in the request flow to preserve a
caller-provided timeout value when it is not None, and use the configured
(http_open_timeout, http_request_timeout) tuple only when no per-request timeout
was supplied. Ensure this behavior applies through Http.get and the
Channel.publish/get_message callers.

Nothing connected AblyHttp and AblyRealtime to the prototypes the factories return. A hasattr loop in the tests was the only check, and it was weak enough to call a class with no implemented members conformant. Have each client name its prototype as a base class, so the relationship is stated where the client is defined and a type checker verifies it. That alone would weaken the runtime check, because an unimplemented member then resolves to the prototype's `...` stub and returns None rather than raising, so the conformance tests are strengthened to match: - the prototype must actually appear in the client's MRO - every member must be defined by the client itself, found by dropping the prototype's own MRO so an inherited stub cannot satisfy it - parameter names, kinds and requiredness must match the prototype, as must whether the member is awaitable The synchronous client is covered too, since unasync generates both sides of that pair. Annotations are excluded from the signature comparison: the prototype spells its types as strings under `from __future__ import annotations` while the clients evaluate theirs, and return types are a type checker's concern. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The clients now declare their prototype as a base class, so calling them AblyHttp and AblyRealtime left the two halves of each pair reading as unrelated types. Name each class after what it is: the default implementation of its prototype. - AblyHttp -> DefaultPubSubHttpClient - AblyRealtime -> DefaultPubSubRealtimeClient - AblyHttpSync -> DefaultPubSubHttpClientSync, through unasync's rename list Neither name is exported, and both are reachable only through create_http_client and create_realtime_client; each class docstring now says as much. Tidy the 4.0.0 migration notes in passing. They no longer spell out the internal rename, which was never part of the public API. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The per-side packages already describe the stateless client in HTTP
terms (
create_http_client()inably.pubsub.server) while the corestill called it Rest. Align the core's naming with that terminology.
