HAIN Protocol (HAINP)

The policy-aware execution and interoperability layer for hybrid AI-native systems.

What HAINP is

HAINP is the policy-aware execution and interoperability layer for hybrid AI-native systems across local, edge, private, and cloud environments.

Execution domains

Shared semantics for local, edge, private, and public execution placement.

Locality constraints

Rules for residency, movement, and permitted execution boundaries.

Routing and fallback

Intent-aware routing and governed degradation paths when preferred execution is unavailable.

Portability and continuity

Context portability plus trace and audit continuity across domain transitions.

What HAINP is not

  • Not a transport protocol
  • Not a replacement for HTTP or other core web standards
  • Not a replacement for MCP as a tool and context access protocol
  • Not a replacement for A2A as a generic agent collaboration protocol
  • Not a base automotive, V2X, or robotics control protocol
