+# Sensor Bench Operator (Internal)
+
+Private operator / inspection workflow UI. **Do not publish** this folder or its
+resources in customer EXEs, public docs, or release zips.
+
+## What lives here
+
+- Workflow UI (`sensor_bench_operator.app.MainWindow`)
+- Inspection steps (`steps/default.json`)
+- Lab component options (`config/options.json`, including Chinese lab labels)
+- Operator locale catalogs (`config/locales/`)
+
+The public exhibition app lives under the repository root (`run.py`,
+`src/sensor_bench/exhibition_app.py`) and must not import this package.
+
+## Run (source)
+
+From the repository root:
+
+```powershell
+python internal/run_operator.py
+```
+
+Or:
+
+```bat
+.\internal\run_operator.bat
+```
+
+Requires the public `sensor-bench` package sources on `PYTHONPATH` (the launcher
+adds `src/` and `internal/src/` automatically) and an importable `orisys`.
+
+## Build private EXE
+
+Uses the same conda env as the public build (`sensor-bench-build-py310`):
+
+```bat
+.\build\create_env.bat
+.\build\build_operator_exe.bat
+```
+
+Output (internal only — do not ship to customers):
+
+```text
+dist/SensorBenchOperator/SensorBenchOperator.exe
+```
+
+The build copies public sensor configs plus operator `options.json`, locales, and
+`steps/` beside the EXE. See [`../build/README.md`](../build/README.md).
+
+## Relationship to public Sensor Bench
+
+```text
+orisys (public SDK)
+  ├── sensor-bench → dist/SensorBench/ (public exhibition EXE)
+  └── internal/    → dist/SensorBenchOperator/ (private operator EXE)
+```
