Two further notes. BTC_BSCB_A2DP_ACT was set before I reloaded the driver (BT0->WL was 0x40000013) and is not set after, with the sink connected and streaming throughout. bt_update does not advance, so BT firmware appears to send a scoreboard update only on change, and the state the driver lost on rmmod/insmod is never restored. The cycle reports are unavailable on this firmware, which is why I have no slot statistics to go with this: fcxcysta[0/5], fcxslots[0/1], fcxstep[0/3], fcxnullsta[0/2].
