RoundTrip implements the http.RoundTripper interface

newClientWithReuse creates a new http client with configurable connection reuse

Connect establishes an SSE connection and returns an SSE response

NewWebSocketClient creates a new WebSocket client

NextEvent reads the next event from the SSE stream

StringToTLS13CompatibleSpec creates a TLS 1.3 compatible ClientHelloSpec by filtering curves

* Emergency cleanup of all active instances * This is called automatically on process exit

* Emergency cleanup of all active instances * This is called automatically on process exit

Helper function to extract number from "key:value" format

Start a local HTTP/2 server with strict flow control settings.

Apply configures the HTTP/2 connection with the specified fingerprint. HeaderPriority is driven by the parsed Exclusive / StreamDep / Weight fields.

Connect establishes a WebSocket connection

NewSSEClient creates a new SSE client

Queue queues a request (simplified for integration tests)

* Manual cleanup function for instances created with createSafeCycleTLS * * @param {object} instance - CycleTLS instance to cleanup

* Alternative approach for tests that need multiple CycleTLS instances * or want more control over instance lifecycle. * * @param {object} options

doProxyRequestWithRetry retries httpbin.org GETs through the SOCKS proxy on 408/502/503 — these are upstream-flake codes from httpbin under proxy load

waitForProxy waits for SOCKS proxy to be ready by attempting to connect

Close closes the WebSocket connection

Close closes the SSE connection
