PermaVid-GT — multi-visit, full method sweep (incl. Cosmos3-Nano)

A GT-multiview PermaVid set where every target frame has real ground truth, so the GT tile is honest full-resolution ground truth. This is the panel that surfaces the methods whose valid outputs live here — most importantly Cosmos3-Nano (the 16B MoT world model; this is its only valid rollout set) — alongside the wider baseline sweep (ViewExtrapolator, TrajCrafter, Voyager, FlexWorld, SpMem, Lyra-2, MatrixGame-3, VACE-prev). Each tile plays its native-resolution output in a CSS grid (max 4 per row); our VACE-14B is green. Use the ▶ Play all bar — every tile plays, seeks and loops in lockstep at the shared 倍速 speed (default 0.5×).
