All six are `from_site_notes`-only (gov-API RdSAP corpus unmoved at 78.9%),
graded against the DB PasHub-assessment oracle (energy_rating_current,
source='lodged'), not the surveyor-entered pre_sap.
A. Manual-Entry boiler efficiency. Extractor read PCDF-Search columns that a
manual survey lacks; mapper returned None for all boilers → the generic
0.80 gas default. Now read `Type of boiler:` / `Heating System (Boiler):`
/ `Is there an open flue?` and resolve the descriptor to its SAP 10.2
Table 4b code. Moves all 7 Wythenshawe manual boilers to the oracle
(4a Hollyhedge back boiler 63.6→53.4=53; group MAE 2.42→0.42).
B. Room-in-roof gable type None → strict-raise. A form variant omits the
gable-type line (genuine field-absence); default None → party `gable_wall`
(U=0.25), mirroring `_api_type_1_gable_kind(None)`. Present-but-unknown
labels still strict-raise. Unblocks 8 & 34 Bucklow Drive.
C. Secondary `Closed room heater` unmapped → add Table 4a code 633.
Unblocks 8 Brinkshaw Avenue.
D. Alternative-wall insulation thickness never extracted → parse
`Wall insulation thickness:` and pass it through instead of the RdSAP 10
§5.4 100 mm favourable default.
E. `Number of heated rooms?` label mismatch → the PDF lodges
`Please enter the number of HEATED rooms:`.
F. HW cylinder thermostat dropped (NEW, systematic). `_map_sap_heating`
never set `cylinder_thermostat`, so a surveyed thermostat defaulted None
and the calculator applied the SAP 10.2 Table 2b Note a) ×1.3 penalty.
Map it ("Y"/"N", gated on a lodged cylinder) as the Elmhurst path does.
Fixes the two worst DB-oracle under-raters (52 Bucklow 59.4→61.8=62;
13 Kerne Grove 65.0→67.1=67).
DB-oracle cohort (148 matched): within-0.5 83.8%→87.8%, MAE 0.427→0.303.
