> **Low Risk**
> Documentation-only change to the OpenAPI spec; no runtime logic is
modified, so risk is low aside from potential client expectation
changes.
> 
> **Overview**
> Documents two new query parameters on `GET /store`: `responseFormat`
(`full`|`agent`) to request a reduced, LLM-oriented response shape, and
`includeUnrunnableActors` to optionally bypass the default safety
filtering that excludes automatically-unrunnable Actors.
