Clarification (classify the claim by its job, not by its subject pattern).

  • Classify the exact atomic claim by what its sentence states and by the conditions that let a reader decide it.
  • The exact ClaimGraph located through the subject pattern supplies the referenced object’s predicate and obtaining conditions; it does not choose the claim’s quadrant.
  • When permission wording is present, use the single permission-word branch in §8.4.1. It separates the possible jobs of that wording without inventing a common “permission result” kind.

Normative rule (single quadrant). Each atomic claim MUST be classifiable under exactly one quadrant L/A/D/E.

Normative rule (no mixed sentences). A conforming boundary text SHALL decompose any sentence that bundles multiple quadrants (typical form: “MUST … if … then … and it is logged …”) into multiple atomic claims before those claims are treated as normative.
