Few queries here:
1.  As a Kessler cascade is (by _definition_) collisional , shouldn't
that be a subpart of 6805.8, as you've got it currently?
2.  What counts as "overpopulation" on a Dyson megastructure?
After all, it would seem the carrying capacity of such a structure to be
somewhat in excess of a planet (see previous emails).
If carrying capacity of a 1 AU Dyson shell is 550 septillion (for
instance), then it would be _under_populated by 400 septillion
blathering yammerheads.
3.  Would ringworlds count as a degenerate form of a Dyson sphere in
your taxonomy, or are they different enough to merit their own type (not
fully enclosing their primary)?
4.  Even though it's definitely not Trav, I'd like to see you restore
6803, perhaps under the new name of "Intelligent Super Objects".  For an
example, https://www.orionsarm.com/eg-article/4667775c449b2 and its links.
