New BFL-API-flux-3-video.json covers all three modes: t2v straight to SaveVideo, i2v fed by Flux3Keyframes, and v2v fed by LoadVideo through VideoToBase64. The tools workflow gains a Flux Virtual Try-On v2 group mirroring the v1 setup; remaining churn in that file is ComfyUI frontend metadata (aux_id -> cnr_id, node order/positions) and the outpaint mode widget value written by the current node schema.
