ECO.8:4.2 - Find the unsupported transfer of a rule
Test the proposed rule in the receiving relation. Does it require information, agreement, trust, authority or an ability to bear a particular cost or risk that is absent there? Does importing it remove a contribution the current arrangement needs?
Repair that concrete mismatch. Clarify an externally purchasable result; retain local discretion where it supplies needed adaptation; use a general access rule where personal favour excludes unknown participants; or coordinate a shared constraint through ECO.7. A mixture is often appropriate, but each relation needs an actual mechanism.
Compare whose purposes and alternatives the repair serves and what it costs others. A current price helps strangers exchange without common goals, but cannot by itself settle every affected right or shared-resource effect.
