The Elmhurst Summary §15.1 lodges "Cylinder Size: Value known" with the measured volume in the "Cylinder Volume (l)" line — the Summary-path equivalent of the gov-API "Exact" descriptor. The mapper had no entry for "Value known" so `_elmhurst_cylinder_size_code` raised UnmappedElmhurstLabel, and even once mapped the measured volume was never threaded through, so the cascade dropped the cylinder storage loss (~468 kWh/yr) from (219) water heating on every measured-volume-cylinder Summary. Per RdSAP 10 §10.5 Table 28 (p.55) a measured cylinder volume is used directly. Map "Value known" → cascade code 6 (Exact) and thread the §15.1 "Cylinder Volume (l)" value into SapHeating.cylinder_volume_measured_l, which `_cylinder_volume_l_from_code` (cert_to_inputs.py:5281) already reads for code 6 — mirroring the gov-API path (mapper.py:1575/1885). Pins simulated case 39 (P960-0001-001431): an age-A mid-terrace on direct- acting electric room heaters (SAP code 691, cat 10, control 2602) with electric-immersion DHW off a 117 L "Value known" cylinder. The full extractor→mapper→calculator cascade now reproduces the worksheet's SAP-rating block EXACTLY — SAP value 36.6365 (band F) and (272) CO2 2056.0731 kg/yr, with (219) water heating 2637.5049 and (255) total energy cost 1802.0039.
