How it works
Match by object type plus exact signed ID, so node -1 and way -1 remain distinct. Report unresolved negative references and duplicate create definitions.
Two nodes feed a created way, which feeds a relation. All three negative references resolve; the positive node reference remains unchecked.
Limits
Up to 20000 objects and 40000 references. Positive IDs refer to unknown remote state. This does not validate geometry, versions, changeset permissions, upload ordering, server rules or whether a change should be uploaded. Nothing is submitted.
