Function adopt_fetched 

pub fn adopt_fetched(
    store: &Rc<dyn DurableStore>,
    package: &str,
    room: &str,
    id: &RecordId,
    bytes: &[u8],
) -> Result<RecordCheckout, TransferError>

Verify bytes another device sent as record id of room, and keep it here: installed when new, merged when this device already holds it. The bytes are only trusted as far as they prove to be that live record.

Errors

Bytes that are not a live record id scoped to room, or storage failure.
