A diagnostic page, not an application. It signs you in with your Sling Microsoft
account and shows exactly what the database knows about you — proving the chain
from Entra ID through Supabase to row-level security works end to end.
Starting…
One-time setup
Paste the anon public key from Supabase →
Project Settings → API Keys. It is stored in this browser only.
Use the key labelled anon or public — never
service_role. The anon key is meant to be public; the page
will refuse the service key if pasted by mistake.
Not signed in
Use the Sling Microsoft account you already use for email.

What the database returns
What row-level security lets you read
These counts come through your own signed-in session, so they reflect the
policies applied to you personally — not what an administrator can see.
A zero is a legitimate answer, not a failure.
