A.2.6:21.1 - With F–G–R (C.2.2)

  • G is Claim scope. Use set algebra (∩ / SpanUnion).
  • F remains the expression rigor (C.2.3); R captures evidence currentness and bounded reliance. Observed loss may bear on the translation-use claim; its permitted-loss tolerance remains in that claim rather than in G or the Bridge profile.
  • Composition. F follows C.2.3’s weakest-essential-support bound. R follows the justified support-composition model or non-aggregate synthesis under C.2.2. G follows §7.2–§7.3 (set rules).
