Why this is canonical

Protocol is the fundamental organizing concept for how systems communicate and coordinate. The layer suffix identifies this as the substrate beneath all AI protocol activity — not a specific protocol but the named coordinate for the protocol stratum itself. The protocol concept anchors a substantial cluster of positions in this portfolio.

Where it fits

A few directions this coordinate opens —

Agent communication protocols
The foundational layer beneath agent-to-agent protocols, MCP implementations, and inter-system communication standards.
AI agent infrastructure and protocol framework companies
Enterprise integration protocols
The protocol layer for enterprise systems where APIs, event buses, and data contracts are coordinated at scale.
Enterprise integration and API platform companies
