"""Wire types.

These are deliberately NOT the domain models. `Instance` carries `team`, `namespace` and
`release_name` — placement details a tenant has no business seeing and no business
setting. The response model is the allow-list that keeps them off the wire, which is why
it is written out by hand instead of derived from `Instance`.
