 To keep the inspected recommendations identical to what gets stored, **both

+KNOWN GOTCHA: the live ``material.type`` enum does not yet carry
+``secondary_heating_removal``, so a Property with a lodged secondary heater
+crashes the catalogue read for that measure. Until the catalogue stocks it, pass
+``--exclude-measures secondary_heating_removal`` (an ASHP row is also absent, but
+ASHP is priced off the rate sheet so it degrades to ``material_id=None`` rather
+than crashing — no flag needed).
