Preserve streaming on FoundationNetworking platforms.
The default URLSessionTransport uses session.data(for:) when FoundationNetworking is available. That call buffers the complete response before http.stream(request) can return.
A long-lived SSE response therefore yields no chunks. A large response can also exhaust memory. Implement incremental response delivery for these platforms before routing Functions streaming through this transport.

ack: valid. Linux buffers because swift-corelibs-foundation has no per-task delegates; the pre-branch Functions delegate was session-level and did stream there. Tracked as a follow-up in SDK-1839 (https://linear.app/supabase/issue/SDK-1839), out of scope for this PR since Linux is build-only support.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Bound the streamed error body.
Data(collecting: body, upTo: .max) permits an unlimited non-2xx response body. A large or non-terminating error response can exhaust client memory or prevent FunctionsError.httpError from being emitted.
Use a finite error-body limit. Cancel or drain the remaining response after the limit.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Preserve bodies when decoded bytes exceed the collection limit.
A compressed response can declare a length at or below 64 KiB but decode beyond 1 MiB. Data(collecting:upTo:) then throws after next has returned the response, so this middleware fails the request instead of returning its body. Use a teeing body wrapper that logs a bounded prefix while preserving the complete stream for the caller.
As per path instructions, this is a functionality-breaking problem that must be resolved before merge.

ack: valid. The 16x margin narrows the window but a >16x gzip ratio still makes the logger throw after next returned. Fix is a bounded tee that never fails the request; tracked in SDK-1841 (https://linear.app/supabase/issue/SDK-1841), sequenced after the pull-based HTTPBody in SDK-1833.

Do not buffer an unbounded streamed upload.
For .stream, this collects every chunk into memory before request execution. HTTPBody supports unknown-length streams, and reportingProgress converts file bodies to .stream. A large body can exhaust memory before URLSession starts. Stream through an upload task or enforce a finite cap before collection.

ack: valid and already marked as a ponytail ceiling in the source. The reportingProgress downgrade of .file bodies to .stream is a good catch. Tracked in SDK-1842 (https://linear.app/supabase/issue/SDK-1842): uploadTask(withStreamedRequest:) with an InputStream bridge, keep .file storage under reportingProgress, finite cap on Linux.
Add missing DocC on send(), clarify the streamed-response buffering comments (unbounded stream, bounded chunk size), document why Content-Length is set explicitly, simplify makeBody, note the buffered-vs-streamed iterationBehavior split on the type doc, and strengthen the buffered-GET test to assert length/iterationBehavior.
AuthClient.Configuration now takes transport: any ClientTransport and middlewares: [any ClientMiddleware] instead of a raw fetch closure, matching the ClientTransport/ClientMiddleware seam introduced in Helpers. Auth's internal HTTPClient no longer goes through the temporary FetchTransport adapter for its own configuration. SupabaseClient keeps wiring its OpenTelemetry-tracing fetch closure into AuthClient through FetchTransport for now; SupabaseClientOptions.global gains its own transport/middlewares in a follow-up.
QueryCapture/RequestCapture only called capturedBody.setValue when the request had a body, so a capture instance reused for a later bodiless request kept returning the previous request's body from bodyString.

…ster transport symbols `HTTPClientTests` reads `HTTPURLResponse.url`, which lives in FoundationNetworking on Linux; the missing import broke the Linux and Linux integration CI jobs. The capability-matrix check flagged every public member of the new transport API as unregistered. They are now listed under `client.request_configuration.custom_http_client`: the per-module `http` configuration properties as entry points, and the `HTTPBody`, `HTTPClientConfiguration`, `ClientTransport`, `ClientMiddleware` and `URLSessionTransport` members as supporting symbols.

swift-corelibs-foundation keeps a file upload on the URLSessionTask, not on the `URLRequest` that `MockingURLProtocol` observes, so the mock sees no body there and the assertion failed on the Linux CI job. The status and response-body checks still run on every platform. Co-Authored-By: Claude <noreply@anthropic.com>
…sion:) (#1326) `SupabaseClientOptions.GlobalOptions` had two ways to configure HTTP: `session` backed the default transport only while `http.transport` was nil, and was also copied into Realtime's WebSocket options. One knob now configures HTTP: pass `URLSessionTransport(session:)` as `GlobalOptions.http.transport`. Realtime's WebSocket session is configured only on `RealtimeClientOptions.session` and no longer inherits a global one. BREAKING CHANGE: `GlobalOptions.init` has no `session:` parameter and `GlobalOptions.session` is removed. See V3_MIGRATION.md. Fixes SDK-1820 Co-authored-by: Claude <noreply@anthropic.com>
…yte AsyncBytes `URLSessionTransport` iterated `URLSession.AsyncBytes` one byte at a time and yielded a chunk at every newline. Against a local Storage server a 200 MiB download took 10 s where curl takes 0.6 s, and the unbounded chunk backlog cost 29 to 44 MB even for a consumer that discards every chunk. The Darwin path now runs a `URLSessionDataDelegate` on the data task: the head is handed back as soon as `didReceive(response:)` fires and every `didReceive(data:)` delivery is one chunk. Same download now takes 0.65 s with a 1 to 2 MB streaming floor. Chunk boundaries follow the network rather than the payload, so the migration note tells SSE consumers to reassemble on the frame separator; the newline-split test is replaced by one that asserts chunks are passed through as received, plus a failure-path test.
