EvidenceFloor

The minimum evidence a proposition must carry before a relation may be asserted at full strength.

This is the knob that stops a cheap structural signal — two people sharing an email domain, a single calendar co-attendance — from being promoted to a strong semantic claim like "works for" or "collaborates with". A relation can declare a floor on two independent dimensions, and an assertion has to clear both:

• minConfidence: the proposition's decay-adjusted confidence must reach this value.

• minAuthority: the proposition's source must be at least this authoritative (see AuthorityTier, where a lower ordinal means more authoritative).

Either dimension may be left null, in which case it is simply not checked; a floor with both null never blocks anything. When an assertion falls short, demoteTo names a weaker predicate to fall back to (for example "works for" → "affiliated with"). If demoteTo is null the assertion is held for review instead.

DICE only carries and checks the floor — it never decides what the threshold values should be or what "weaker" means for a given predicate. Those are the consumer's to declare on each Relation.
