# Internal app (superseded) The internal calibration and laboratory tooling this directory was reserved for now lives in [`apps/autocal`](../autocal/README.md) — the 5-axis calibration platform control application. That app keeps the property this stub existed to protect: it is **not** part of the customer-facing product. It is not packaged by `build/studio` and must not enter the customer installer. This directory is otherwise unused; it is kept only so the move is documented.
