#A.6.P:4.7 — Two‑view / polarity discipline (no silent role flips)

Preface node heading:a-6-p-4-7-two-view-polarity-discipline-no-silent-role-flips:10846

#Content

A RPR‑pattern SHALL specify how the same relation is expressed from both “sides” without polarity flips:

• Either keep both endpoints visible with the same polarity-preserving token, or
• declare explicit inverse tokens and require them for inverse prose.

Implicit role flips (“B validates A” without explicit inverse) are prohibited in Tech/normative prose. This is already a core rule for basedness patterns and is generalised here.
