BLACKBOX

BLACKBOX is a fleet black box on the VAST video stack. After a close call, the camera, the objects, the distance, and the model's read are on one clock. The App button opens this page. The Rerun viewer plays Toronto AV drive 01, 13:25–14:00. That recording holds each clip as video, YOLO tracks and one-second trails, in-path proximity for people, bicycles, and vehicles, a time-to-contact lane, and Cosmos3-Reason event lines on the risk-2 clips. On the 13:55 clip the ego car is slowing on a narrow street. The recording has 65 tracks. A bicycle in the centre path reaches proximity 0.84. The shortest time to contact is 1.8 seconds, on a car. Cosmos times a pedestrian in the path at 13:55, 13:56, 13:58, and 13:59. The stored caption says cyclist. We did not build the video stack. VAST stores the clips and the index. Cosmos captions each five-second segment. YOLO writes the boxes. Rerun supplies the viewer. We added the episode view, the exporter, the tracks, proximity, time to contact, and the Cosmos timing pass. Risk and event names on 13:55 are still inferred. Re-ingest has replaced 2 of 6 clips on each of the two parent chunks, and 13:55 still has the old caption.
