- BetaListDreamsResponse
  - `data` BetaDream[], required
    - `type` 'dream', required
    - `id` string, required
    - `inputs` BetaDreamInput[], required
      - union
        - object — An input memory store the dream reads from. The dream never mutates this store.
          - `type` 'memory_store', required
          - `memory_store_id` string, required
        - object — Input session transcripts the dream reads.
          - `type` 'sessions', required
          - `session_ids` string[], required
    - `outputs` BetaDreamOutput[], required
      - `type` 'memory_store', required
      - `memory_store_id` string, required
    - `status` 'pending' | 'running' | 'completed' | 'failed' | 'canceled', required — Lifecycle status of a Dream.
    - `created_at` string, date-time, required — A timestamp in RFC 3339 format
    - `ended_at` string, date-time, required — A timestamp in RFC 3339 format
    - `archived_at` string, date-time, required — A timestamp in RFC 3339 format

    - `usage` BetaDreamUsage, required — Cumulative token usage for the dream across every pipeline stage.
