16/// Represents the consistency status of cached blockchain blocks, tracking gaps in the block sequence.
17///
18/// This struct helps determine the optimal sync strategy by comparing the highest cached block
19/// with the last continuous block number. When these values differ, it indicates gaps exist
20/// in the cached data that require special handling during synchronization.
