Force	Pull	Push
Brevity	One word such as “same” is fast.	It hides the object, action, direction, rule, tolerance, and stop.
Practical interoperability	Teams want shared labels and reusable mappings.	Shared labels and running code are not semantic identity or proof of a safe use.
Relation versus use	One semantic relation can remain fixed.	Different uses of it can have opposite polarity or different evidence.
Direction	A relation may be symmetric or oriented.	Every proposed use still has its own source-to-receiving direction.
Evidence evolves	Counterexamples and warrants change.	Evidence change should reopen reliance without silently reidentifying the Bridge.
Version drift	Canons and models change by edition.	The relation profile needs an applicability and as-of basis.
Practical safety	Cross-context reuse can save work.	Suitability, reliance, authorization, and actual performance must not collapse.
