Filter-presence and visibility gate in a casting mould
Filter presence in the mould must be checked before the production step begins. An occluded filter region or an incorrect mould recipe can make a simple presence/absence decision unreliable.
Proposed output: filter-presence evidence, mould recipe and HOLD reason. Pour-permission integration and physical seating conditions are design assumptions; this scene is not process-safety approval.

Solution approach
Locate the filter position for the mould recipe using reference geometry. Evaluate presence evidence in the visible ROI and distinguish occlusion or position uncertainty from a missing filter. The proposed permission gate produces HOLD for an invalid image or unresolved position.
