Current: settlement proposal

Review the independently proposed patch below, including its unchanged callers. Work in the real product frontend and the transactional backend. Accept a connector if it occurs anywhere in a station connector list and enforce individual power limits. Concurrent overlapping plans share the site power budget across every selected station. Split charging minutes at peak-rate boundaries, round the final cents upward, and show scheduled kWh from power times hours. Pricing and the persisted activity summary disagree with the domain policy. Repair both layers, preserving currency rounding, cancellation handling and repeated-plan semantics. Run bash test/run.sh. The public checks drive Chromium against native HTTP and a real database; each scoring group includes regression safeguards.
