Acknowledgements

Special thanks to @rockerBOO for the design discussion behind the new NetworkTrainer extension seams (#943), which grew out of his Self-Flow proposal in #913. The squash-merge unfortunately did not surface his commits in the auto-generated list below.

特に @rockerBOO 氏に深く感謝します。新しい NetworkTrainer 拡張シーム (#943) の設計議論にご協力いただきました。これは氏の Self-Flow 提案 (#913) を起点としたものです。squash merge の都合で下記の自動生成リストに氏のコミットが反映されなかったため、ここで明記します。

This release's refactoring was largely carried out by Claude Code (Opus 4.7), with review by Codex (GPT-5.5). My thanks to both. All responsibility for the resulting code rests with the maintainer.
