Graduate research 042 into ADR 0275 and to-be 53, so issue numbers stop colliding

Numbers taken by reading a repository many branches write at once collide;
one counter in a module of the mesh's own, advanced by compare-and-set,
ends that at the source. The operator delegated the five open questions
on 2026-10-10; each is decided as the research recommended. The glossary
gains the issue tracker, retires "ticketing system" and lists ticket as a
homonym, since ADR 0258 already uses it for an answer's one-time token.
