The Case Analysis-Synthesis Theorem (cont.)

In order to think of tackling even the roughest sketch toward a proof
of this theorem, we need to add a number of axioms and axiom schemata.
Because I abandoned proof-theoretic purity somewhere in the middle of
grinding this calculus into computational form, I never got around to
finding the most elegant and minimal, or anything near a complete set
of axioms for the "cactus language", so what I list here are just the
slimmest rudiments of the hodge-podge of "rules of thumb" that I have
found over time to be necessary and useful in most working settings.
Some of these special "precepts" are probably provable from genuine
axioms, but I have yet to go looking for a more proper formulation.

To see why the Dispersion Rule holds, look at it this way:
If "x" is "o" (a terminal node), then the presence of "x"
makes no difference on either side of the equation, but
if "x" is "|" (a terminal edge), then both sides of
the equation reduce to "|".
