The full RdSAP-Schema-21 label is "Double between 2002 and 2021" (double
glazing installed 2002-2021, SAP 10.2 Table 24 code 3). When the Elmhurst
Summary PDF wraps the trailing "and 2021" into an adjacent table cell that
the extractor joins away, the surfaced label truncates to "Double between
2002" — the same artifact already handled for "Triple post or during".
`_elmhurst_glazing_type_code` raised UnmappedElmhurstLabel on it, blocking
the whole Summary (surfaced on the simulated-case-46 multi-attribute
worksheet). Added the truncated form as a code-3 alias.

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.

The Elmhurst §15.1 "Insulated: No Insulation" label was lodged but absent
from `_ELMHURST_CYLINDER_INSULATION_LABEL_TO_SAP10`, so
`_elmhurst_cylinder_insulation_code` raised UnmappedElmhurstLabel — blocking
the parse of every Solar PV example cert (the solar `before` lodges "No
Insulation"). An uninsulated cylinder has no insulation *type*, so per the
no-misleading-insulation convention it maps to `cylinder_insulation_type =
None` rather than naming a material; the lodged 0 mm thickness carries the
storage-loss signal the SAP 10.2 Table 2 dispatch needs.

Slice 3a. The inverse of Epc.from_sap_score: the minimum SAP rating in a
band (C → 69, B → 81, …), used as the Optimiser's repair target for an
INCREASING_EPC goal (goal_value "C" → target SAP 69). Keeps the
band-target derivation in the domain rather than re-coupling to
backend.app.utils.epc_to_sap_lower_bound. 8 tests incl. round-trip
through from_sap_score; pyright strict clean.
