- main.spec: include dist/updater.exe in datas (when present) - main.py: extract embedded updater.exe next to main.exe on launch - updater_client.py: _MEIPASS fallback to TEMP if extraction fails - release.ps1: build updater FIRST so main.spec can embed it Now users can deploy main.exe alone; auto-update still works because main.exe self-extracts updater.exe on first launch.
