F.0.1:5.3 - Quick checks for later use

• String check. If the only evidence is the same spelling, no cross-source relation has been established.
• Stance check. If one source describes a design and another a performed occurrence, state that difference before any relation or row use.
• Direction check. Preserve the direction and limits of the actual relation; a reverse or broader reading needs its own support.
• Chain check. Keep intermediate meanings and accumulated loss visible; test a direct endpoint relation separately when needed.
• Contradiction check. Incompatible relation claims about the same cells remain explicit rather than being averaged into a vague alignment.
• Row check. A Concept-Set row needs the relation and bounded receiving-use judgment required by F.7 and F.9; a label or confidence level cannot admit a member.
