DetectionExecutionService

Run current-frame detection while delegating engine lifecycle to the manager.

PARAMETER	DESCRIPTION
session_repo	Interface used to retrieve the session and its current frame for inference. TYPE: UIApplicationInterface
engine_manager	Manager responsible for detection-engine lifecycle. TYPE: DetectionEngineManager

__init__(session_repo: UIApplicationInterface, engine_manager: DetectionEngineManager) -> None

execute_for_current_frame(s_id: SessionId) -> None

Detect the current frame and refresh its selected and editable detections.

PARAMETER	DESCRIPTION
s_id	Session identifier whose current frame is processed. TYPE: SessionId

Raises: Exception: Propagates model, filtering, and storage failures.

Note

Label and detection-confidence settings filter model output before Layer A storage. An empty label selection permits every class. Layer B machine boxes are replaced even when the frame was initialized earlier; manual boxes survive.
