No source gives a ready acceptance test. Combining measures the papers use gives a proposal: generate at the longest length you need, score per-segment brightness/imaging quality and a motion measure, compute first-vs-last delta, run a copy-first-clip control, and separately test whether the model returns to an earlier place (memory), which the papers say these methods do not provide. This is synthesis, untested.
