Long agent calls no longer get cut off. The proxy now waits up to 10 minutes for a provider to start responding, up from about 4. Streaming requests that sit silent for more than 20 seconds get SSE keep-alive comments every 15 seconds, so load balancers and clients don't drop the connection while a large prompt is processing. A new X-Grepture-Timeout header sets the timeout for a single request and overrides your rule timeouts, so one long call gets more time without loosening everything else. Rules still on the old default timeouts have been raised to 600 seconds. See Timeouts for details, including how late errors are delivered on streaming responses.
