Microsoft Foundry can discover and invoke a deployed Epistema assurance endpoint through A2A over HTTPS, submit a proposed commitment, and receive a structured, read-only assessment before organizational action proceeds.
The release
This is more than a local semantic mock-up and more than an architecture diagram. A real upstream agent surface resolved Epistema’s Agent Card, invoked the deployed endpoint, and received a completed semantic readout over the A2A path.
Agent platforms provide identity, context, orchestration, tools, evaluation, guardrails, and execution. Epistema addresses a different question at the handoff point:
Is this consequential action warranted by the evidence and authority available now?
The answer can be to proceed, constrain, defer, gate, reject, or request reassessment. The readout informs that decision; it does not make it.
The buyer frame
Consequential autonomy has two sides: what happens if the system is wrong, and what justifies proceeding. This marketecture places semantic assurance in the larger ecosystem of identity, policy, runtime, observability, evaluation, and control.
Epistema’s position: a specialist semantic-assurance capability that can sit beside agent platforms and orchestration runtimes, helping bind evidence, interpretation, authority, and current-state support to consequential commitments.
The next horizon
The release establishes a working assurance boundary and a practical foundation for deeper enterprise integration.
A deployed endpoint can be discovered and invoked by a compatible Foundry agent through A2A.
A readout can qualify unsupported approval evidence without authorizing or mutating governed state.
Agent Card discovery, deployed A2A transport, and read-only semantic assurance provide a practical foundation for integrating Epistema with enterprise agent platforms.
