- Move Shared Runtime preparation to the installation hook and add persistent UI/file opt-out.
- Restrict file and model download paths, checkpoint loading, and configuration parsing across the suite.
- Remove Dedicated Runtime choices and migrate saved workflows without shifting widgets.
- Exclude development files from Registry archives while retaining runtime metadata and Unicode paths.
- Document installation, repair, and manual runtime cleanup.
Validation:
- 59 targeted existing tests, actual fresh runtime installation, and live Step speech/editing.
- File containment, restricted loader compatibility, settings persistence, and archive contents checked.
- Manager queue/restart flow remains untested on the local installation.
