BREAKING CHANGE: DeviceInstructionMessage no longer accepts the close_scan_group, open_scan_def, or close_scan_def actions.

  • scan: Remove legacy scan GUI models (6e1f479)

Publish gui_visibility and signature metadata without the deprecated gui_config payload.

BREAKING CHANGE: available_scans no longer includes gui_config. Scan controls should use gui_visibility and signature metadata.

  • scan: Remove legacy scans (99dec37)

Remove the generator-based scan worker, legacy scan and stub classes, and legacy queue paths. Load and run scans through the direct ScanBase API.

BREAKING CHANGE: Legacy scan classes and generator-based scan workers are removed. The scan server now accepts only direct ScanBase subclasses as scan plugins. Imports from the removed legacy modules are no longer available.
