"""Every override component must be wired through the WHOLE chain.

The finaliser reader (`_ROW_TYPES`, component -> landlord table) and the overlay
registry (`_COMPONENT_OVERLAYS`, component -> overlay mapper) must cover exactly
the same set of components. If a component is classified + stored but has no
reader entry, the finaliser silently never writes its `property_overrides` rows;
if it has no overlay entry, the row never reaches the calculator. This guard
keeps the two registries in lock-step (it would have caught the missing
main_fuel / glazing / construction_age_band reader entries).
