Does the computed glideslope indication meet obstacle clearance (i.e.
stepdown altitudes and whatnot) even if the approach is flown a couple
of dots low on the glideslope indication? Or does the pilot/autopilot
need to be absolutely sure that the approach is flown smack in the
middle or a couple dots high?

I think that's kind of like asking, "Does the MDA meet obstacle clearance
even if you go below it?".

I think the answer to both questions is the same, "There's some
TERPs-defined buffer built in, but from the pilot's point of view, all you
gotta know is don't go below what the procedure says until you can see the
runway".
