Destination | Caller-owned stream that receives the first-page prefix |
Info | Receives the latest availability status and validated offsets |

使用上の注意
- The destination receives only the linearized first-page prefix and remains owned by the caller
- Reads use 64 KiB chunks and honour the operation cancellation token
