Release notes
Changelog
Features
- Extract the Pi command line into a pure pi_command module: six hand-copied argv literals in runner.py become one function (Issue #1231; PR #1296)
- Extract Pi session launching into src/orbi/pi_session.py: 8 definitions and ~610 lines leave runner.py (Issue #1262; PR #1299)
Reliability and recovery
- 发版竞态：push 撞 (fetch first) 的败者把已落地的版本 commit 判为失败，release 票进 ai-blocked (Issue #1289; PR #1292)
Deployment and operations
- 里程碑推进只接受 CLI：托管租户收到提问却给不出引擎认的答案，且建 milestone 与开 release 票仍需人工 (Issue #1290; PR #1293)
