Thanks for your posting. I read it. Good.

Note the black 'hole' in the top of the Descent Stage:

(zoom in). They look like they might have come close to a 'brew-up'.

Not sure what you mean by that; the hole was always there and ascent
stage ignition was always intended to be "fire-in-the-hole".

There was a thermal and micrometiorite sheild -
http://jeffreyellis.org/tlmp/files/facts/lm_descent.gif. I think it was
also intended to prevent the Ascent Stage thrust from getting into all
the tanks etc on the Descent Stage - no BOOM. Propellant was vented,
but then there was the pressurising gas and any residual oxygen in storage.

I knew about the shield but thought it only covered the tanks, not the
descent engine compartment in the center. The cutaway drawing you linked
doesn't make that clear either. There aren't many pictures of the
descent stage from above, but this one shows an open hole

There's a drawing of the hole in the descent module he

Also this: http://www.apollosaturn.com/Lmnr/descent.htm "A teflon-coated
titanium blast shield that deflects the ascent engine exhaust out of and
away from the descent engine compartment is secured to the upper side of
the compartment, below the thermal blanket".

What interested me was the apparent darkening of the lunar soil around
the descent stages caused by their landing engine.
