The 2026 development
IAB Tech Lab adapted advertising infrastructure for agent communication and execution.
The governance gap
Interoperability standards define message shape, not authority. Two compliant agents can still agree to a transaction neither principal authorised.
Where CAIN-42 fits: Moat 2 — Security-Context Continuity
Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.
Keep authority outside the message standard: a mandate and a settlement check on each side, independent of the protocol's fields.
How the wiring works
- Map the protocol message to an action and a principal.
- Check the principal's mandate outside the protocol.
- Settle only when both sides' mandates agree.
- Record the protocol version and the authority decision.
What is real today
PROPOSED A design mapping only. No dedicated implementation exists yet; do not buy this as a finished control.
No IAB Tech Lab implementation exists here. CAIN's interop adapters are real but not certified against that standard.
