Overview

The drop-in maintenance layer and stability contract for component-observable continuous systems.

TrueLoop sits between a digital host and a photonic, wave, quantum, RF, sensing, or in-memory analog substrate. The host keeps orchestration and semantics. The physical layer keeps the dense transform. TrueLoop keeps the delegated physical state inside a declared operating tolerance.

The complete product has four parts: exactly budgeted preflight, a five-state stability contract, evidence-scoped controller-family guidance, and an Ed25519-signed run record. The controller is one member inside that layer, not the whole product.

Each ordinary cycle consumes one current full response vector and returns one complete writable configuration. The active default performs linear host work and carries bounded auxiliary state per writable control. Flat scaling refers to sequential acquisition depth, not zero traffic or zero arithmetic.

Fit requires a component-resolved response, a measured feasible target, same-cycle timing, declared configuration bounds, and operation inside a matching evidence cell or a monitored boundary pilot. Unknown evidence remains boundary. It is never promoted to fit or converted into a universal decline.
