The highest slot number for which at least one shred has been received and inserted into the validator's blockstore.

This value represents the validator's current view of the maximum slot for which it has received network data, regardless of whether the slot is complete or has been fully processed.

Key characteristics:

• Always a non-negative integer representing a slot number
• May be higher than the current processed slot if shreds are received ahead of processing
• May be lower than the network's current slot if the validator is behind
• Does not guarantee that all shreds for this slot have been received
• Indicates the validator's progress in receiving network data

Use cases:

• Monitor validator's data reception status
• Detect network connectivity issues
• Assess validator synchronization with the network
• Debug shred reception and processing pipeline
