Detailed Description

This module defines the ACIP protocol packet types used for session management, WebRTC signaling, and discovery service communication. ACIP is a binary protocol over TCP used by the ASCII-Chat Discovery Service (ACDS) and clients.

CORE RESPONSIBILITIES:

1. Session management packet type definitions
2. WebRTC signaling packet type definitions
3. String reservation packet type definitions
4. Discovery service control packet type definitions

PACKET RANGE ALLOCATION:

ACIP packets use range 100-199 to avoid conflicts with ascii-chat protocol (1-99).

• 100-109: Session management
• 110-119: WebRTC signaling
• 120-129: String reservation
• 150-198: Control and utilities
• 199: Generic error response

INTEGRATION WITH OTHER MODULES:

• network/packet.h: Uses ACIP packet types in packet_type_t enum
• network/acip/acds.h: ACDS-specific message structures

Note

ACIP packets are defined in the same packet_type_t enum as ascii-chat packets, but use a separate numeric range (100-199).

All ACIP packets use the same packet header structure as ascii-chat (magic, type, length, CRC32, client_id).
