Doesn't hurt to ask, but Quanta still refuses to release these publicly

Reviewed the diagram carefully. The only issue I spotted was that the
+5VSUS line into the RTC charger comes from a yellow switching voltage
regulator, despite the RTC charger coloured green. Either it has to
come from somewhere else, or the RTC charger has to be yellow, or the
switching regulato

a few questions -- for some i can guess at the answer, but better
to ask and be sure:
- if there are no USB devices inserted, is there an advantage

Any chance of getting schematics and PCB files this time around? I doubt you
renegotiated your contract with Quanta to allow for this, but it doesn't
hurt to ask.
