Deletes a kv namespace. Fails while `spec.deletion_protection` is set.

- **Path** `DELETE https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/kv_namespaces/kv-namespace`
- **Scope** `data:write`
- **Effect** `destructive` — a successful call removes data; the CLI asks before it runs.
- **Collection** [kv_namespaces](/docs/api/kv_namespaces)
- **Query** `etag`, `allow_missing`, `validate_only`
- **Operation** answers with an `Operation`; the result is `Empty`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | The name of the kv namespace to delete. Required. |
| `etag` | `string` | Delete only if the current etag matches. |
| `allow_missing` | `bool` | Succeed when the Resource does not exist. |

## Errors

- [`UNAUTHENTICATED`](/docs/api/errors/UNAUTHENTICATED) — No valid key or token was presented.
- [`PERMISSION_DENIED`](/docs/api/errors/PERMISSION_DENIED) — The key lacks the method's permission.
- [`RESOURCE_NOT_FOUND`](/docs/api/errors/RESOURCE_NOT_FOUND) — The named Resource does not exist or is not visible.
- [`ETAG_MISMATCH`](/docs/api/errors/ETAG_MISMATCH) — The etag sent does not match the Resource's current etag.
- [`INVALID_STATE`](/docs/api/errors/INVALID_STATE) — The Resource is in a state that forbids the call.
- [`DELETION_PROTECTED`](/docs/api/errors/DELETION_PROTECTED) — `spec.deletion_protection` blocks the delete.
- [`IDEMPOTENCY_KEY_REUSED`](/docs/api/errors/IDEMPOTENCY_KEY_REUSED) — An Idempotency-Key was reused with another body.
- [`IDEMPOTENCY_IN_PROGRESS`](/docs/api/errors/IDEMPOTENCY_IN_PROGRESS) — The first call with this Idempotency-Key is still running.

Every error arrives in the body [Errors](/docs/platform/errors) describes.
