Crime Detection Outage, Car Wash Task Issues Diagnosed

Crime detection task experienced a 4-hour outage with miners receiving no challenges. The Car Wash element underperformance stemmed from pipeline randomness issues, improperly re-annotated ground truth data, and rectangular bounding box oversizing on thin objects. Team clarified that data leaking is unlikely given continued poor model performance on new post-deployment data; properly annotated data now impacts previously high-scoring miners.

• •Crime detection task down 4 hours; miners received zero challenges
• •Car Wash pipeline requires reworking for randomness and variety
• •Bounding box oversizing allows inflated scores on partial detections
• •Ground truth re-annotation rollout caused task degradation
