Detailed Description

Manages session_model.log for raw streaming content.

Opened at configure time, used during run_streaming to record the full user/assistant transcript. The session_model.log is the unfiltered stream (includes think blocks, unlike session.log which gets spdlog-formatted engine operations).

Version

2.0.1
