Open Standards

Microsoft's Agent Control Specification and CSA's AARM both name the runtime-governance layer, from opposite ends. AARM writes mandatory requirements, including universal pre-execution interception and tamper-evident receipts. ACS writes the interface: lifecycle hooks, normalized verdicts, fail-closed enforcement. What was a gap diagnosis now has two competing specs.

AGNTCY is the Internet of Agents project, and it just archived its own Agent Connect Protocol. Reading that archive shows the layer dividing into describe and invoke.
