Protocol

Rezi’s engine boundary is binary:

• ZRDL: drawlist bytes written by core, consumed by the engine
• ZREV: event batch bytes produced by the engine, parsed by core

These formats are:

• little-endian
• 4-byte aligned
• versioned
• validated strictly

Start with:

• Event batches (ZREV)
• Drawlists (ZRDL)
• ABI pins
