#  ↑ GitHub already performed a DNS-level domain-control check for us

✅ M0  TRUST.md / POLICY.md / policy.py / positive + adversarial regression tests
✅ M1  Evidence pipeline; `python -m src.verify <domain>` end to end
✅ Review fixes  entity anchoring / fail-closed domain age / A6 first-party link / A3 list / A7 gov TLD / +6 adversarial cases
✅ M2  220-org survey → 53 entities generated by the pipeline; daily re-verification; reproducible dist/ + cosign signatures
✅ M3  api.realurls.org live; @realurls/mcp on npm; listed in the official MCP Registry
✅ M4  realurls.org evidence pages, category browsing, /builders and /verify; browser extension built (store listing pending)
✅ M5  Scale-out: D1 storage, bulk sources, sharded batch builds, AI review layer, App Store anchor (A9), owner self-attestation,
       on-demand examination of anything the API is asked about, remote MCP endpoint, aggregate demand
