Changed
- Managed inference_idle_timeout_secs lowered from 1800 to 900 seconds. The 30-minute ceiling traded too much failure-detection latency for stall tolerance; 15 minutes still covers twice DeepSeek's documented ten-minute queue and multiples of the observed three-minute relay stalls, and the downstream watchdog (deadline minus 30 seconds) already converts a true stall into a retryable proxy_stream_error, so the extra wait mostly delayed discovery.
- The managed idle timeout now applies to every proxied channel, including first-party api.deepseek.com routes. The resilience projection is no longer special-cased: an explicit value remains user-owned and wins on every channel alike, and the proxy's DeepSeek-specific 660-second upstream byte window is unaffected. The DeepSeek guard test now asserts the managed timeout is present instead of invented.
