+   suite went **6F/1P/3skip → 10 pass / 0 fail / 3 skip** (skips = emulator-mode tests needing a different
+   fixture mode).
 2. **Modbus non-standard profiles** — pin pymodbus in the fixture Dockerfile (or update expected values for 4.x).
 3. **FOCAS** — reconcile the 127.0.0.1-mock topology with the remote-fixture model.
 4. **AbLegacy** — deploy an AbLegacy sim fixture (none on host).
