Isolation you can explain
When a school administrator asks whether another school can see their students, the answer must be architectural — not "we hide that button."
Our baseline
Every NyansapoSoftware multi-tenant product starts with tenant-scoped policies in PostgreSQL. Admin UIs still gate routes, but the database is the source of truth for access.
Corporate vs product platforms
Our corporate site is single-tenant by design. We still use RLS so only authenticated admins can write portfolio and lead data — same discipline, different tenancy model.
