We need modify? User says issue perhaps expects fix. Need examine current visible logic. It uses 12 samples and considers cull if all blocked. Partial visible no cull because sample maybe misses small gap, flicker. Need design hysteresis temporal and more coverage perhaps needs projection screen occlusion. Existing 3 confirmation but it validates exact same view (camera move .5) and train center .5 and raw all sample, culls after 3. It might flicker 150ms staleness especially sample misses small part. Need large issue user says previous. Need likely ask? Implement maybe introduce visibility grace and reappearance hysteresis. 12 corner insufficient for Invalid prompt: your prompt was flagged as potentially violating our usage policy.
