Okay, so let's go from there. What is or is not happening when the
remote control is used that causes the near-instant shutoff, that is
not or is happening when the main power switch is cycled?

I presume that when the remote is used, some monitoring circuit
detects an out-of-spec PS voltage immediately after power-on. Using
the mains switch removes power from even the monitor circuits and
clears the error code.

That's plausible. So how would you troubleshoot that?

Next question -- Assuming this analysis is correct, why does the presumed
out-of-spec voltage -- or its detection -- NOT occur when there's a "hard"
power cycling?

It is part of a start up routine initiated by the remote cycling?
