Detailed Description

Bitmask identifiers for the flags byte in every C2P-ARQ frame.

The first byte of every frame is a bitmask rather than a fixed type ID. Using a bitmask allows future frames to combine roles and lets the parser use bitwise-AND for matching, which is more resilient to single-bit noise corruption than strict equality comparison.
