_qom.band_limited_qom requires lo > 0 (true band-pass). Several stillstanding-study reports compute a low-pass-only 10 Hz speed instead, and in-source analysis there suggests a 0.3–10 Hz band-pass under-reports QoM by ~14% for that material. Migrating those analyses needs an explicit low-pass mode: accept lo=0 (or band=(0, hi)) and switch to a low-pass Butterworth, documenting the semantic difference so results aren't silently shifted.
