The classifier is intentionally multi-sport. Volleyball is the strongest public demo lane today; tennis, table tennis, and badminton have solid checked-in references; pickleball and basketball are active improvement lanes.
Hero lane for public demos, indoor gym clips, team separation, and rally overlays.
Racket and court evidence with strong local reference clips.
Small-court/table geometry plus paddle-size cues.
Long-racket and court-shape signals for indoor play.
Tracked as an active lane for paddle/court disambiguation.
Gym-ball and player-pattern lane for open-gym scenes.

Known misses are left as unknown instead of pretending certainty.
The checked-in harness runs the same pipeline: video → YOLO26 MLX → tracker → sport classifier → overlay video. Larger local engines can be compared with refereai compare when installed.
RefereAI MLX focuses on sport inference, overlays, session artifacts, and a human review loop for messy amateur sports footage.
The sweet spot is fast local understanding: take a clip or phone stream, produce reviewable evidence, and let a person correct the system when the overlay is wrong.
