### Terminal Traceback & Material to Help Reproduce Bugs | 终端traceback（如有） + 帮助我们复现的测试材料样本（如有）

_No response_

Start by reproducing the OpenRouter configuration on Windows with the reported API URL redirect and proxy settings. Capture the missing terminal traceback and compare the OpenAI-compatible request path with the project's API integration. Done means the conversation succeeds through OpenRouter or the failure is reported with a clear diagnostic.
