message as a `SYNCING`, `VALID` or `INVALID` response. A consensus engine MAY

### Assumptions about Execution Engine Behaviour
This specification assumes execution engines will only return `SYNCING` when
there is insufficient information available to make a `VALID` or `INVALID`
determination on the given `ExecutionPayload` (e.g., the parent payload is
unknown). Specifically, `SYNCING` responses should be fork-specific; the search
for a block on one chain MUST NOT trigger a `SYNCING` response for another
chain.
## Merge Transition
To protect against attacks during the transition from empty `ExecutionPayload`
