NIS2 quickscan

Compute a NIS2 readiness indicator from the DNS and email layer. Maps the quickscan evidence onto NIS2 Article 21.2 measures (a–j) and returns a weighted 0-100 score, per-measure status, evidence rows, critical gaps, and fix suggestions. Evidence that is not applicable for a given domain (e.g. DNSSEC on a TLD that does not support it) is excluded from the measure's score and reduces the measure's effective weight in the total. The result is a readiness indicator only — full NIS2 compliance also requires audit of web applications, supply chain, organisational processes, and training.
