SubarrayInterface Tango Device

Provides the Tango interface for an SKA subarray device.

This class extends ObsInterface with the standard subarray command set and long running command (LRC) support via LRCMixin, which supplies a TaskExecutor-backed task_executor and the associated LRC attributes.

Subclasses must override the execute_* methods for each command and apply the submit_lrc_task() decorator to make them long running commands.

Observation state is driven by writing to the signals inherited from ObsInterface, primarily via _update_obs_state(). The started_* and completed_* callbacks on AbstractSubarrayInterface manage the command_in_progress portion of the observation state automatically when using submit_lrc_task().

Use AbstractSubarrayInterface directly only when you need to supply your own task_executor implementation (e.g. via ComponentManagerLRCMixin).
