Detailed Description

Vital channel message with integrated CRC-64.

Wrapper structure for redundant channel messages that ensures data integrity across transmission.

Usage pattern:

Sender: Wrap data with CRC, send wrapped message
Receiver: Receive wrapped message, unwrap (verify CRC)
On mismatch: Trigger safe-state
