Tenant isolation, explained

How one business’s data stays away from another’s.

How it actually works

Each business-owned row carries a business id. The database tables have row-level security policies defined, but GorZesk’s own backend connects with a role those policies do not restrict, so RLS does not run against its traffic. The real protection is that the API checks the caller’s membership and role before any query touching a business runs.

For AI

The model never chooses which business to read. The system fixes the business from the authenticated session before any tool runs.

Test it

  • Write a test that a user of business A cannot read or write business B.
  • Test the negative path for every new table and endpoint.
