## Definition

ABIS (Agent Business Interaction Standard) addresses how to represent what happens between AI agents and business systems — Business Interactions and Business Outcomes — across agents, protocols, and systems. ABIS is complementary to protocols such as MCP and A2A; it does not replace them.

- Conformance, certification, registry, and Internet-wide discovery are NOT implemented in v0.2.0
- Native result CONFIRMED is not equivalent to Business SUCCESS
