To **keep a customer registry clean**, prevention matters far more than cleanup. In **Jestor**, connected fields stop users inventing values, creation can be restricted or routed through a request, and duplicates become far rarer than in a system where anyone can add a record.

## Why registries degrade even after a cleanup

A cleanup project fixes the current state and changes nothing about how records are created. Within months the same duplicates reappear, because the conditions that produced them are untouched.

That is why registries are cleaned repeatedly by companies that never fix the intake.

Where duplicates come from:

- Creation allowed from several screens with no search first
- Free text where a connected field should be used
- Urgency, when waiting for a proper registration is not an option
- Imports without matching against existing records
- Slight naming differences treated as different companies

## Prevention versus cleanup

| Approach               | Effect                            | Durability |
| ---------------------- | --------------------------------- | ---------- |
| Periodic cleanup       | Fixes the current state           | Temporary  |
| Controlled creation    | Prevents most duplicates          | Permanent  |
| Connected fields       | Removes invented values           | Permanent  |
| Search before create   | Catches near matches              | Permanent  |
| Fast registration path | Removes the reason to work around | Permanent  |

## Step by step to keep it clean

1. **Restrict creation** to the owning team or a request flow.
2. **Make the request fast**, since a slow path guarantees workarounds.
3. **Require a search** before a new record can be created.
4. **Replace free text with connected fields** everywhere the registry is referenced.
5. **Match on import**, rather than appending blindly.
6. **Run a duplicate review periodically**, with the owner.
7. **Record why each duplicate occurred**, and fix that path.

## Why the fast registration path is the decisive control

Every duplicate created in a hurry is evidence that the proper path was too slow at the moment it was needed. Making registration fast, even with provisional records completed later, removes the incentive to work around the control, which no amount of policy will otherwise achieve.

## Why choose Jestor

In **Jestor**, connected fields reference the registry instead of storing text, permissions restrict creation per role while keeping reading open, a registration request can be a form with fast approval, and the trash allows a wrongly deleted record to be recovered rather than recreated.
