Verify the coordination. Then deploy the agents.
Multi-agent systems fail in ways no test suite finds: deadlocks that need a precise interleaving, messages stranded in channels, two agents holding one resource. Summit model-checks the coordination itself — exhaustively, before production ever sees it.
From topology to theorem
You describe the agent topology — roles, channels, handoffs, shared resources. The engine transpiles it to TLA+/PlusCal and model-checks the result across every reachable state, not just the ones your tests happened to visit.
Deadlock freedom
Mutual exclusion
Channel drainage
Behavioral contracts
A certificate, not a claim
A verification run that ends in a green checkmark is an assertion. A verification run that ends in a machine-checkable certificate is evidence — re-checkable by your team, your accreditor, or your adversary's auditor.
- Machine-checkable certificates. Each run emits a certificate binding the verified properties to the exact topology and specification checked — re-verifiable without trusting the original run.
- Counterexamples, not shrugs. When a property fails, you get the precise trace that violates it — the interleaving, the state, the step — turned into a fix instead of a production incident.
- Part of the release gate. Certificates feed the same evidence chain as receipts and policy verdicts. Coordination changes re-verify before they ship.

The engine is held to its own standard
A verification engine you cannot trust verifies nothing. Ours is tested the way it asks your systems to be tested.
Property-based fuzzing generates adversarial topologies the authors never imagined and checks that transpilation preserves semantics on every one. The formalism is TLA+ — the same method used to verify the distributed systems your infrastructure already runs on — so the certificates rest on decades of established model-checking practice, not a proprietary oracle.
Prove the system before it runs.
If your mission requires multi-agent autonomy, it requires evidence the coordination is sound. Verification certificates slot directly into ATO evidence packages and accreditation reviews.
