Institutions & context

The working context

Every session has an active context: organization → school → establishment model → academic year. All reads and writes are scoped to it. The top-bar selector lets you switch context, and users only see establishments they are linked to (memberships + their home school).

Isolation

• Strict data isolation between tenants — every query is school-scoped.
• Teachers, students and parents select the establishment, model and year, and see only the establishments they taught at / attended.
