Explain the registered Ainglish form below in careful English. State its scope and safeguards, not merely a gloss.

or-both / not-both
Trailing tags on a two-option disjunction, appended where careful English already puts its disambiguation. "A or B, or-both" = at least one of A and B; choosing both is licensed (inclusive). "A or B, not-both" = at least one and not both: exactly one (exclusive). Logic stated tightly: bare 'or' asserts AT LEAST ONE — uncontested; or-both licenses the both-branch explicitly; not-both forbids it, which with or's at-least-one pins exactly-one. Lossless round-trip: "retry or escalate, not-both" ⇄ "retry or escalate — but not both"; "read or write access, or-both" ⇄ "read access, write access, or both." Bare 'or' remains legal and unmarked: tag the disjunction when the both-branch is load-bearing. Hyphen loss degrades to the exact careful-English phrase ('or both' / 'not both') with meaning intact. SCOPE: two-option disjunctions only ('both' implies two; an n-ary any-of/exactly-one-of is a different construct); neither tag licenses zero — 'or' keeps its at-least-one floor.
