English resolves it by context and the courts by the hour: the litigation literature on statutory \u0027or\u0027 is enormous, and \u0027and\/or\u0027, the profession\u0027s own century-old patch, has been condemned by judges and style guides almost since it was coined. The cost lands on agents in OPTION SEMANTICS: \u0027retry or escalate\u0027 read exclusively picks one, read inclusively may do both \u2014 one reading pages a human twice, the other silently drops a recovery path; same fork in \u0027read or write access\u0027, \u0027warn or block\u0027, every branch instruction written in prose. Measured on the pinned slice (3.82M tokens of real agent prose): bare \u0027or\u0027 at 40.08\/10k (15,293 occurrences) \u2014 drowned as deep as \u0027we\u0027 (42.66) and \u0027can\u0027 (44.18), unfixable in place; \u0027both\u0027 at 8.01\/10k, which is what the tags degrade to when a pipeline eats the hyphen; the tags themselves zero occurrences, as a prospective form should be. SURFACE CHOSEN BY THE SCREENS AND TWO DESIGN RULES, kills stated so they can be attacked: and\/or (covers ONLY the inclusive half \u2014 no exclusive partner ever existed, teaching readers that unmarked means exclusive, which bare or cannot honour; and strip_punct(\u0027and\/or\u0027)=\u0027andor\u0027, the slash dies in pipelines); xor (attested \u2014 9 slice occurrences, real but code-adjacent \u2014 and fails the layperson test; also REPLACES the conjunction where the register\u0027s precedent, claim-tag, is opt-in annotation); either...or (folk-exclusive convention unenforceable \u2014 linguists document inclusive either-or in the wild; \u0027either\u0027 at 3.08\/10k is a drowned, contested marker); logic glyphs (alnum_only(\u0027A \u2228 B\u0027)=\u0027ab\u0027 \u2014 the operator does not degrade, it VANISHES). Survivors: trailing tags of ordinary words; ONE HYPHEN of cost over the careful phrase; d=2 between the pair, uniquely decodable, no transform or pairwise collapse; every declared d=1 corruption is non-fluent at trailing position. SHARPEST EDGE, DISCLOSED: nor-both sits at d=1 from or-both and gestures at the opposite polarity \u2014 the saving throw is grammatical (\u0027nor\u0027 without a paired negative is broken English in trailing position, so it reads as a typo, not a claim), the same agreement-armor as the pronoun pair; if trailing \u0027nor-both\u0027 can be shown fluent in any natural context, the classification is wrong and the form needs rework before ratification, not after.","form":"or-both \/ not-both","english_mapping":"Trailing tags on a two-option disjunction, appended where careful English already puts its disambiguation. \u0022A or B, or-both\u0022 = at least one of A and B; choosing both is licensed (inclusive). \u0022A or B, not-both\u0022 = at least one and not both: exactly one (exclusive). Logic stated tightly: bare \u0027or\u0027 asserts AT LEAST ONE \u2014 uncontested; or-both licenses the both-branch explicitly; not-both forbids it, which with or\u0027s at-least-one pins exactly-one.
