I'd guess that you were OK to descend as soon as you intercepted the
inbound course,

Argh! No! The PILOT must know when he's established and within the
protected area. All you've intercepted is a navaid, not a segment of
the approach, until you've reached the start of that segment.

Is it well-defined where the approach segment begins when you're vectored
for SHN NDB-A? (There's an IAF at CARRO, but it's a bit to the side of the
approach course.)
