Check the fit.
Test the real interface before closing the loop.
PreflightTrueLoop checks the interface, keeps the device within tolerance, and records whether the stability contract held.

The application keeps running while TrueLoop qualifies, maintains, and verifies the physical hardware underneath it.
Test the real interface before closing the loop.

Evaluate through the hosted service, then deploy the same interface beside the hardware for production latency, data residency, or air-gapped operation.
Hardware measurements, controlled simulations, and projections are labelled separately.
