> Notes:
> 5. SANA-WM cannot support sequence parallelism: its bidirectional gated delta
> recurrence carries state across frames, so a rank cannot denoise a slice of
> the token sequence in isolation. Doing so would need a distributed scan or
> an all-gather before every GDN block. The remaining ❌ columns are simply
> unvalidated on this model, not known-broken.
> **Step execution note:** Helios supports single-request step execution only;
> use `max_num_seqs=1`.
