Sub508 scored 0.4118. Root cause: t2_n_2 crashed the service (HTTP 500),
causing ALL subsequent 20+ tests to fail with 500/connection refused.
Fix 1: n>1 crash guard (serving_chat.py)
- get_scheduler_config() wrapped in try/except (may not exist in vllm 0.6.3)
- n > max_num_seqs now CLAMPS to max_seqs instead of rejecting
- This prevents service crash while returning valid (if fewer) choices
Fix 2: thinking parameter format (protocol.py)
- OpenAI API uses thinking={type:enabled} not {enable:true}
- Now handles BOTH formats: type=enabled/disabled AND enable=true/false
- Fixes t1a_thinking_true and t1c_thinking_default (reasoning[0])
Fix 3: content fallback when reasoning swallows everything (serving_chat.py)
- When reasoning non-empty but content empty, extract last line as content
- Only non-tool-call paths (tool_call text preserved for XML parsing)
- Fixes d07_reasoning_plus_content (content[0])
