I don't deny any measured facts. I know what the circuit is - or is supposed to be. I *don't* know what your NanoVNA behaves like, apart from what you describe. Either the diode is leaky (which to me seemed/seems more likely) or what's "behind" your Vbat terminal is problematic/leaky. What do you measure with the NanoVNA off, i.e. no Vdd present?
