-Add one extra manual device row to an existing circuit:
-
-```bash
-npm run dev:add-manual-circuit-row -- <circuitId>
-```
-
-Default inserted values:
-- `name`: `Test sub device`
-- `displayName`: `Beleuchtung WC`
-- `phaseType`: `single_phase`
-- `quantity`: `1`
-- `powerPerUnit`: `0.05`
-- `simultaneityFactor`: `1`
-- `cosPhi`: `1`
-
-The script prints the created row id.
-
-Delete the test row again:
-
-```bash
-npm run dev:delete-circuit-row -- <rowId>
-```
+Manual device rows and multi-device circuits can be created directly in the
+circuit-list editor. The former development scripts for direct database writes
+were removed because they bypassed project revisions and persistent undo/redo.
