    "answer": "WC2 explicitly replaces H1's ten with 12 practice units for the named UTC day and sensor. H2 remains missing because WC3 lacks the time basis and sensor identity needed to associate it with that interval. The fixture therefore supports 23 of 24 required hourly intervals, not complete coverage. Preserve revision and missingness separately without interpolating H2 or making an emissions, compliance or regulatory-reporting conclusion.",
