The HTTP client wraps payload construction (delegating to ChatCompletionsRequest.fromLlmRequest) and response parsing (delegating to ChatCompletionsResponse.ChatCompletion / ChatCompletionChunkCollection) for both non-streaming and streaming Server-Sent Events responses. END_PUBLIC Key behaviors: - Tri-state call timeout policy: * httpOptions == null OR timeout() empty: applies a default 5-minute call timeout to prevent indefinite hangs in the common unconfigured case. * httpOptions.timeout() == 0: respected as the explicit caller opt-in to infinite hang for long-running streams or batch jobs. * httpOptions.timeout() > 0: applied directly as the call timeout. This default intentionally diverges from the GenAI HttpOptions convention (which treats unset as infinite) as a defensive measure since this client does not yet have HTTP retry support. - SSE prefix handling accepts both "data: foo" (with space) and "data:foo" (without space) per the SSE spec, matching providers that omit the trailing space. - A single malformed JSON chunk in a streaming response is logged and skipped rather than aborting the entire stream. IOException (connection-level) still propagates as a stream error. - Content-Type is defensively forced to application/json by replacing rather than appending, preventing duplicate or conflicting headers if a caller supplies their own Content-Type. - Headers parameter accepts null (treated as no extra headers) and is stored as an ImmutableMap for thread-safe reuse across concurrent generateContent calls. Test additions (16 total, +12 new): - HTTP error status (4xx/5xx) propagation for both streaming and non-streaming. - Empty body propagation. - Streaming continues past a single malformed chunk. - SSE "data:" prefix accepted with or without trailing space. - Custom headers reach the wire. - Caller-supplied Content-Type is overridden, not appended. - baseUrl with and without trailing slash. - Constructor tri-state timeout (null, zero=infinite, positive). - Constructor null headers parameter. All testSubscriber.await() calls bounded to 500ms to prevent test hangs.
