- Executors and relay helpers get an environment without any configured Plane token / webhook secret (design 8: executors hold no Plane credentials). - Windows runner: Set-Location -LiteralPath, and a failed cd writes exit=97 instead of running the agent in the wrong directory. - schtasks launch: escape apostrophes and pass the script path as \"...\" so paths with spaces survive PowerShell 5.1 native quoting. - State and heartbeat files are written temp + fsync + rename. - Tests for the above plus codex run/resume command shapes and unique run dirs.
