Archive this repo

This code is not supported by any team at Adobe, but it still bears our name. This can be confusing to developers, and when things don't work (and they won't) we still have to support them. Best to archive to send a clear signal that this code should NOT be used, or only for reference.

The issue requests archiving the commerce-cif-graphql-integration-reference repository because it is unsupported and may confuse developers. Review the repository's current status and confirm that the completed state is an archived repository clearly marked as unsupported; no source files or tests are identified.
