Questions on Public Beta Metrics, Multi-Model Support, and Repo Access

Hi Team,

I have three quick questions:

1. Public Beta: Can we launch a public beta during the hackathon to gather user metrics? Would those metrics be considered as evidence for the "Community Impact" judging criteria?

2. Multi-Model Choice: Is it acceptable to offer users a choice of other models (for flexibility/comparison) as long as Amazon Nova remains the default and core engine for the submission?

3. Repo Access: The rules mention keeping access open through the Judging Period. Is it safe to revoke the testing accounts' access to our private repo on April 3rd?

Thanks for the support!
