I noticed a discrepancy while starting validation: the PR body references https://github.com/SQLtattoo/azd-az700-all-in-one, but the template entry being added points to https://github.com/SQLtattoo/az700env for the source, preview, and demoguide URLs.

Which repository should be considered the preferred/authoritative source for this offering before we proceed with validation?

Hi @rob-foulkrod, the repo is https://github.com/SQLtattoo/azd-az700-all-in-one but even the other one will land in this.
Go with https://github.com/SQLtattoo/azd-az700-all-in-one.

Thanks!
