A.21:6 - Bias annotation

• Green-display bias. A display can look like a decision. Recover the gate result and applicable profile.
• Neutral-value bias. An algebraic neutral can hide an unknown or unrun check. Preserve applicability and evaluation state before mapping.
• Profile-label bias. A profile name can look authoritative. Require its applicable rule and any separate authority relation.
• Infrastructure bias. Publication and replay fields can look like the gate itself. Keep the decision result primary and add infrastructure only for its triggered use.
