- Line 802: Update the isN1xManagedVllm condition to require both the
N1X_MANAGED_VLLM_SERVING_PRESET value and a trimmed upstreamProvider equal to
"vllm-local", so the N1x timeout and token reserve apply only to the intended
backend.

Outcome
N1x local-vLLM sessions retain a usable prompt budget and allow slow compaction to finish instead of entering a permanently busy state. The exact 32,768-token Qwen profile now reserves its 4,096-token reply budget and permits compaction for up to five minutes.
Reason
The N1x profile inherited OpenClaw's 20,000-token compaction reserve, leaving only 12,768 prompt tokens, and NemoClaw's standard 120-second safeguard timeout was too short for this device. On the reported workload, compaction can take longer than two minutes and the failed operation leaves subsequent prompts blocked.

Gateway timestamps show the two-stage operation ran from 19:26:40 to 19:29:48 UTC (about 188 seconds), exceeding the previous 120-second safeguard limit; a subsequent request returnedOK.Review notes
The initial OpenShell response-stream idle timeout remains visible as a clear per-request error; this change addresses the reported permanent-busy cascade and compaction budget on the exact N1x profile. Other managed routes, including the same model with a 262,144-token window, keep the existing 120-second/default-reserve behavior. User documentation is unchanged because this is a generated runtime-policy correction with no new user workflow.
