## What changed

Producer-side tools call this additive. It breaks exhaustive switches, strict parsers and generated client enums.

Affects `result.type` on `POST /accounts/{account_id}/ai-search/instances`.

New value: `d1`.

can now return "d1"

## Who is affected

Code that reads POST /accounts/{account_id}/ai-search/instances (result.type).

```
switch (response.result.type) {
  // existing branches …
  // no branch for "d1"
  default:
    throw new Error("unexpected type");
}
```
