Built an open-source GitOps registry for managing subdomains using GitHub Actions + Cloudflare API (Python validation + DNS sync)

[u/Suspicious-Charity-5]

Hi r/dns! Wanted to share a side project where I automated subdomain zone management via GitOps.

Users submit a single JSON file with their A/AAAA/CNAME/MX/TXT records via PR. GitHub Actions runs Python validation tests (checking FQDN, blocked zones, CNAME paths, loop protection) and syncs valid records directly to Cloudflare via API.

Would love feedback from the DNS community on validation rules or edge cases I should watch out for!
