What it can't do on its own

Your key is stored encrypted, per user, and read server-side only — just in time, for one action. It never reaches the browser and never reaches a model.

Anything outward-facing — sending, publishing, paying, changing an order — waits for your approval, and that gate lives on the server. Refusals land in the same append-only audit trail as the things that went through.
