Successful response (OK)

- BetaManagedAgentsListMemoryStoresResponse — A page of `memory_store` results, ordered by `created_at` descending (newest first).

    - `type` 'memory_store', required
    - `id` string, required — Unique identifier for the memory store (a `memstore_...` tagged ID). Use this when attaching the store to a session, or in the `{memory_store_id}` path parameter of subsequent calls.
    - `name` string, required — Human-readable name for the store. 1–255 characters. The store's mount-path slug under `/mnt/memory/` is derived from this name.
    - `description` string — Free-text description of what the store contains, up to 1024 characters. Included in the agent's system prompt when the store is attached, so word it to be useful to the agent. Empty string when unset.
    - `created_at` string, date-time, required — A timestamp in RFC 3339 format
    - `updated_at` string, date-time, required — A timestamp in RFC 3339 format

    - `archived_at` string, date-time — A timestamp in RFC 3339 format
