#A.6.B:6.3 — The “triangle decomposition” for mixed sentences

Preface node heading:a-6-b-6-3-the-triangle-decomposition-for-mixed-sentences:7250

#Content

Normative rule (decomposition). A conforming boundary text SHALL decompose any mixed sentence that expresses (i) an entry condition, (ii) an obligation to satisfy/enforce it, and (iii) an observability expectation into the three quadrants:

• A: admissibility predicate (A-*)
• D: duty/commitment referencing the gate (D-* → A-*)
• E: evidence binding referencing the gate (and carriers) (E-* → A-*)

This is the canonical repair for “contract soup” around validity, authorization, compliance, audit, and security boundaries.
