When the district CISO, the school's lawyer, or an auditor asks "prove it," you have a screen to show them. The audit log demonstrates exactly who accessed what. The AI usage trail demonstrates exactly what student data was sent to a third party. The threat model document at scripts/ops/THREAT_MODEL.md describes every attacker we've defended against and every gap we acknowledge.
When a parent invokes their FERPA rights, the response is under five minutes — they get a self-service portal, they get an export, they get a disclosure log, and the whole exchange is audited. No paper trail to lose.
When your school leaves Nova — whether because we failed you or because a board chose differently — you take your data with you in one click. SOPIPA-compliant JSON export, all tables, all relationships intact.
And when an attacker eventually tries something, you see it in real time on the audit-log dashboard with the denied attempts in red.
