Independent observation
Varqo queries the authoritative provider state rather than treating the agent's own output as evidence.
How Varqo works
An integrity control loop between AI intent and real-world state.
Varqo determines what must be true for a workflow to continue, independently proves those states across systems, and controls dependent execution from the result.
Interactive control simulator
See what changes when provider success is not enough.
Choose a scenario and run the workflow. The simulation follows control patterns exercised in live Varqo experiments; it does not call a live provider.

HELD—The control decision
Dependent actions move only when their required state is proven.
Varqo prepares the proof before the consequential write whenever possible. After the write, it binds only the runtime identity returned by the provider, executes an independent verifier, and evaluates the observation against the required outcome.
A successful write response is evidence of the action — not automatic permission for the workflow to continue.

Safety principles
The verifier is independent. Ambiguity never becomes permission.
The control boundary is designed around explicit proof rather than model confidence or a provider's success label.
Requirement-bound verdicts
Evidence counts only when it proves the specific condition the downstream workflow depends on.
Fail closed
Missing verifiers, malformed responses, unknown states, transport failures, and exhausted polling remain unresolved.
Safe evidence
Durable records preserve proof topology and verdicts without persisting raw tasks, provider bodies, or credential-like values.
