What happened
On February 24, 2021, welder Umesh Ramesh Dhake was performing spot welding at the ASAL plant in Chakan, Pune. A robotic arm unexpectedly began moving and struck Dhake in the head and neck. He was rushed to the hospital but succumbed to his injuries.
What broke inside the model
The robotic system's safety sensors failed to halt the movement of the robot when the worker entered the cabin. This technical fault, described as a sensor snag, allowed the arm to move while the worker was in the immediate path of the machine.

This entry sits in the index's predictive wing: a system that scores, ranks, perceives, or steers rather than generates. Realm's runtime layer is built for the generative and agentic systems now moving into these same decision seats, where it watches a model's internal state and holds an unsupported claim or an unchecked action before it commits. The control gap on this record, an automated decision that reached people with no runtime check in front of it, is the same gap. The index keeps predictive failures on the record because the pattern carries straight into the systems shipping today.
