Schema coverage (datatypes/epc/domain/mapper.py):
- SAP-Schema-18.0.0: full-SAP shape ≡ 17.1 → from_sap_schema_17_1, no normalisation.
- SAP-Schema-16.0: same reduced-field 16.x path; default the omitted `tenure`
field in _normalize_sap_schema_16_x (metadata; SAP cascade never reads it).
Genuinely sparse 16.x certs (missing core fabric fields) still fail loud.
- Regression tests + sap_18_0_0.json / sap_16_0.json fixtures; 0 new pyright errors.
Autonomous triage of the worklist (scripts/hyde/autonomous_run_findings.md):
- Found + diagnosed 2 bugs (flagged, NOT fixed): (1) MAPPER — full-SAP openings
lodged in mm read as m → multi-million-m2 windows → SAP clamps to 1 (uprn_
10093117227 / 10090317693 / 10091636031); (2) CALCULATOR — database heat-pump
fuel code 39 mis-priced as gas, over-rates ~14 (uprn_10093114053).
- Most certs map within +/-4 of lodged.

SAP-Schema-16.2 (datatypes/epc/domain/mapper.py):
- 16.2 is structurally an RdSAP-17.1 cert under a different name; add
_normalize_sap_schema_16_2 (field renames + defaults) and dispatch to the
tested from_rdsap_schema_17_1 mapper. uprn_100020933699 maps → SAP 71.
- Honour a "Single glazed" windows description when multiple_glazing_type="ND"
(was defaulting to double) → RdSAP-21 code 5; eng 72→71 (lodged 70).
- 4 regression tests + sap_16_2.json fixture; 0 new pyright errors.
Flat party-wall fix (domain/sap10_calculator/worksheet/heat_transmission.py):
- Full-SAP flats carry flatness in dwelling_type, not property_type, so the
party-wall default fell through to the 0.25 house value instead of the RdSAP
Table-15 flat 0.0. Add _is_flat_or_maisonette_dwelling fallback + regression
test. uprn_10093116529 80→81 (matches the cert's lodged party u_value 0).
Accuracy corpus pins (tests/domain/sap10_calculator/test_real_cert_sap_accuracy.py):
- uprn_10093116543 (SAP-17.1 gas-combi semi): engine 81 (Elmhurst 77; documented
full-SAP→RdSAP residual — measured wall/floor U + PCDB boiler vs RdSAP defaults).
- uprn_10093116529 (SAP-17.1 g/f flat): engine 81 (Elmhurst 78).
devcontainer: add poppler-utils (pdfinfo) for the documents-parser PDF fixtures.
