Admin: invitations

What it does

The platform is invite-only. Sign-up is blocked unless the email exists in invited_emails. The very first user is auto-seeded as bootstrap admin; subsequent users must be invited.

Required inputs

• Email — lowercased, validated.
• Note — optional context (e.g. "Acme NetEng team").

Example output

`` Invited: charlie@example.com Created: 2026-05-01 18:50 Used: — Invited by: alice@example.com ``

When Charlie signs up, the trigger marks the row as used and lets the auth row through.
