Khalim Conn-Kowlessar 4c0ccad882 PasHub SAP accuracy: semi-exposed-unheated floor → Table 20, not §5.14 🟩
`_PASHUB_FLOOR_EXPOSURE` mapped the surveyed "Semi Exposed (unheated)"
floor label to `is_above_partially_heated_space` (RdSAP §5.14, constant
U=0.7). A floor semi-exposed to an enclosed UNHEATED space belongs in
§5.13 Table 20 `u_exposed_floor` (band-B as-built U=1.20). §5.14's U=0.7
is reserved for a floor above a *partially* heated space. #1602
transposed the two branches; the too-low U under-counted floor loss on
the 9 label-carrying cohort fixtures → a shared over-credit.

Triangulated against all three siblings + the calculator docstring: the
gov-API code-2 "To unheated space" (mapper.py:4797) and Elmhurst
`_is_floor_exposed_to_unheated_space` (mapper.py:5970) both route to
Table 20; rdsap_uvalues.py:1416 documents Table 20 as collapsing exposed
and semi-exposed-to-unheated into one lookup. One-line data flip,
from_site_notes-only (gov-API RdSAP corpus untouched, still 78.9%).

Adjacent Ronald St mid-terrace pair (the clustered signal): 10 Ronald
60.35→59.02 (oracle 59), 12 Ronald 60.79→59.36 (oracle 59). Cohort vs
DB oracle (portfolio 838 effective_sap) 83.3%→86.9% within-0.5, MAE
0.377→0.348, no built form regresses, all 7 verified dwellings unchanged
(none carry the label). pashub harness 79.5%→82.4%, MAE 0.389→0.367;
ratchets tightened 0.78→0.82 / 0.40→0.37. pyright zero-new.
