 patch_chat_template.py — Fix non-thinking mode '!!!!!' output
 
-Root cause: Qwen3.5-MoE's chat_template adds '<think>\n\n</think>\n\n'
+Root cause: Qwen3.5/3.6-MoE's chat_template adds '<think>\n\n</think>\n\n'
 when enable_thinking=false. This empty think block causes the model to
 degenerate into outputting nothing but '!'.
 
 Fix: Remove the empty think block so the model generates directly.

+Verified on real machine 2026-08-20:
+  - Model: /root/public-storage/models/Qwen/Qwen3.6-35B-A3B
