# Trust stack

> Who they are and what they may do. One profile. Every gate.

Sign-in, gates, saved results, and agent authority share one account. Do not restart from zero in the next product.

## The loop

| Step | What happens                            |
| ---- | --------------------------------------- |
| 1    | Look up a saved result                  |
| 2    | Run a new check only if needed          |
| 3    | Save it on a profile                    |
| 4    | Reuse before access, payment, or action |

## Building blocks

| Piece             | What it is                                                |
| ----------------- | --------------------------------------------------------- |
| **Profile**       | Your NEUS account: identity, results, agents              |
| **Hosted Verify** | Sign-in and checks in the browser                         |
| **Check**         | One trust decision ([catalog](../verification/verifiers)) |
| **Gate**          | Published checks you embed with one ID                    |
