Legacy LTX-Video 13B BF16 requires full transformer residency and errors out when VRAM is short: "MOLD_OFFLOAD is not implemented for this legacy transformer yet" (crates/mold-inference/src/ltx_video/pipeline.rs:398, as of 1503696). Every other large family routes through the shared AdaptiveResidencyPlan planner.
Scope: wire the legacy LTX-Video transformer into the adaptive offload/streaming path (or the block-streaming runtime pattern used by FLUX/SD3/Z-Image), so 13B dev/distilled run on 24 GB-class cards instead of erroring.
Worth a quick priority check first: if LTX-2 fully supersedes LTX-Video 0.9.8 for users, deprecating 13B BF16 may be the better resolution than building offload for it.
