XB8 stuck on sub-split upstream -- no mid-split, upload capped at 35 Mbps

My XB8 (CGM4981COM) is ranging only on sub‑split upstream channels (10–40 MHz), with no mid‑split and no OFDMA upstream, so my upload is capped at ~35 Mbps despite a 1.2 Gig plan. Please check whether mid‑split is live on my node, and if so push the enhanced‑upload bootfile and re‑provision my upstream. If frontline can't, please open an engineering ticket.
