docs: fix RD-25's decision 4, and name the pattern behind three misses

Decision 4 said the parent keeps seven outputs while decision 5, four lines
below, said all eleven remain and are re-emitted from children. Seven is how
many the parent raises; eleven is how many it declares. The acceptance line
copied the wrong one, and satisfying it would have broken
`org-template.page.ts`, which binds all eleven.

RD-08, RD-23 and RD-25 are the same mistake: a decision describes the design
in one vocabulary, and the acceptance line counts something else that shares a
word. Name what the command counts before writing the number.
