Khalim Conn-Kowlessar e02e6a76e1 Preserve an existing more-off-peak cert meter under a heating overlay 🟩 ... A landlord heating override DESCRIBES the dwelling, so its assumed off-peak meter (Dual/E7) is a coherent default — it must not downgrade a cert that already lodges a more-off-peak meter (e.g. property 709874's 24-hour all-low tariff). The overlay opts in via keep_existing_off_peak_meter; _fold_heating then keeps the cert's meter when both it and the desired meter are off-peak. Heating MEASURES build HeatingOverlay directly and leave the flag False, so they still re-meter for real (Elmhurst re-lodges 18-hour -> Dual on a storage install) — the cascade pins stay green.
