True keeps the diagram whatever "Delete library diagrams not updated for" says; the plan's own retention still applies.

`PUT /orgs/{org}/diagrams/{id}/kept`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Keep a diagram from the library retention. |
| What does it take? | A JSON body of type [`SetDiagramKeptBody`](https://docs.plotwork.dev/api/schemas.md#setdiagramkeptbody). |
| What does it return? | Status 200 with a body of type [`DiagramKept`](https://docs.plotwork.dev/api/schemas.md#diagramkept). |
| What can go wrong? | `400` the body is not valid; `401` not signed in; `403` the role may not (orgs.forbidden), or the request came from an origin that may not make changes; `404` no such organisation or diagram, or the caller is not a member, or the diagram is in a folder the caller may not use; `429` too many requests; `503` organisations are not set up on this server. Every failure uses the one error envelope. |
