Current: eligibility repair

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. An eligibility regression changes which plans are accepted. Repair the domain rule and preserve persistence, capacity checks and error handling. Run bash test/run.sh. The public checks drive Chromium against native HTTP and a real database; each scoring group includes regression safeguards.
