The deal's third_party_surveyor_identifier is now required by the log
and amend flows: the trigger contract rejects messages without it
(blank treated as missing, since a blank resource makes OpenHousing
silently drop the appointment), and LogJobRequest/AmendJobRequest carry
it as a required field. The ABRI_RELAY_DEFAULT_RESOURCE fallback and
its config/terraform/workflow wiring are removed as dead code.

Carry third_party_surveyor_identifier on the Abri trigger message and
through dispatch into the log and amend flows, booking the job against
that resource. LogJobRequest gains the optional resource field
AmendJobRequest already had; the client falls back to the configured
default surveyor when the deal names no third-party resource, so
existing deals behave unchanged.

Positive input ventilation sourced from the loft is treated as natural
ventilation under SAP 10.2 §2 (24d) — matching the MechanicalVentilationKind
.NATURAL contract — so the label now resolves instead of raising
UnmappedElmhurstLabel and blocking the whole Elmhurst Summary. Surfaced on
8 WCHG Elmhurst certs (e.g. 29 Piper Hill Avenue, 38 Bucklow Drive).

Add pashub_accuracy_wythenshawe fixtures + a sibling accuracy module,
built from project_code
[Wythenshawe WH:SHF RAs - WH:SF - 240426 - 494493718748] the same way as
LRHA WAVE 3 (#1620). First run: 149 computed / 19 blocked / 0 errored,
within-0.5 76.5%, MAE 0.665. Ratchets baselined to this cohort; the 19
blocks are separately-ticketed mapper-label gaps (floor 'Same dwelling
below' ×10 dominating), not tuning.

Teaches the pashub `from_site_notes` mapper the electric-storage-heater and
room-heater families, following the existing boiler/heat-network split exactly
(fix at the mapper boundary, ADR-0015 — never mis-rate, never strict-raise deep
in the calculator). Adds:
- Table 4e Group 4 storage charge-control codes (2401/2402/2404) and Group 6
room-heater control codes (2602/2605), each gated on its own system group so a
control label never takes a wrong-group 2xxx code.
- The Table 4a system code from the surveyed heater type lodged in the "Heating
System (Other)" field (`community_heat_source`): Fan storage 404, slimline
402, PCDF-Search product ⇒ HHR 409 (RdSAP 10 p.80), room heaters 691/694.
- A 2404⇔409 coherence guard: high-heat-retention controls on a non-HHR storage
type is a surveyor contradiction and fails loud rather than rating a mismatch.
All codes taken from the SAP 10.2 spec (14-03-2025 PDF) and already present in
the calculator's inventories — no calculator change.
LRHA WAVE 3 (lincs rural) accuracy: 8 computed / 96 blocked → 45 computed / 59
blocked / 0 errored (within-0.5 46.7%, MAE 2.989); ratchets re-baselined to the
new coverage. Guinness cohort (208) + gov-API corpus unchanged; pyright --strict
adds zero new errors.

5 Paxton Place (deal 507639151845, uprn 10070864419) had a STALE fixture.
The same PAS Hub survey (report B74AA5A4-…, inspected 29 Jun 2026) has two
accredited revisions in S3: V2 (uploaded 6 Jul, ventilation "Natural",
SAP 80) and V5 (uploaded 14–15 Jul, ventilation "Mechanical Extract -
Centralised", SAP 76 — the current version). Our committed fixture was the
superseded V2; the portfolio-838 oracle tracks the latest V5 (76). Our
engine faithfully reproduces BOTH (V2 → 80.4, V5 → 75.6) — the +4.38 miss
vs the DB oracle was a fixture-version mismatch, NOT an engine over-rate
(a parallel over-credit sweep found no spec-correct from_site_notes lever;
every channel is faithful).
Refreshed the fixture to the V5 PDF (image-stripped, text layer preserved,
6.7MB→0.27MB, per scripts/build_pashub_accuracy_fixtures.py) and set the
manifest to C76. 5 Paxton flips from the cohort's largest miss to a
within-0.5 hit: DB-oracle gauge 86.9%→87.4% within-0.5, MAE 0.348→0.327.
Pinned via test_paxton_fixture_is_v5_resurvey_sap_76 (asserts a literal 76
against the V5 fixture) — a canary, because hubspot_deal_data.pre_sap is
still stale at C80 and a fixture-builder rerun would revert the manifest.
Confirmed against pashub: the current survey is SAP 76 (Khalim).

13 Walsden (deal 499630239947, uprn 77179782) has TWO distinct gov-EPC
assessments: the PAS Hub site-note re-survey we parse (26 May 2026,
accredited SAP 64, backed by rd_sap_site_note files) and a SEPARATE
later lodged cert (24 Jun 2026, SAP 68, registered, no site-note). The
portfolio-838 baseline latched onto the 24-Jun SAP-68 cert; our engine
models the survey it was given and reproduces its own accredited 64
(64.19). 6 of 7 Walsden Street homes have pbp oracle == PAS Hub survey
SAP exactly — #13 is the lone collision.
A durable regression pin (asserts our SAP within 0.5 of a literal 64,
not the manifest value the fixture-builder can revert to a colliding DB
row) documents the provenance so nobody "corrects" the target to 68.
13 Walsden is a known re-survey-diverges outlier, not an engine
under-rate; confirmed against pashub (Khalim, 2026-07-15e).

`_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.

* Electric-immersion DHW: bill at 100%, not the space boiler's efficiency 🟩
A separate electric immersion heater (SAP water-heating code 903) is 100%
efficient (SAP 10.2 Table 4a) and the space-heating boiler provides no water
heating, so Appendix D2.1 Eq D1 (the boiler seasonal-efficiency cascade) must
not apply to it. But `_water_heating_main` resolves DHW to the SPACE main — a
gas/oil boiler keeps its PCDB record — so three water-efficiency branches in
cert_to_inputs billed the immersion-heated cylinder at the boiler's ~87% summer
efficiency (a mongrel: electric fuel price x gas-boiler efficiency):
1. the scalar `water_eff = water_pcdb_main.summer_efficiency_pct / 100`,
2. the SAP §9.4.11 / Table 4c(2) -5pp no-interlock adjustment, and
3. the Eq D1 (winter, summer) seasonal pair from `pcdb_main`.
Gate all three on `not dhw_is_electric_immersion`; the correct immersion path
(`_water_efficiency_with_category_inherit` -> 1.0, Eq D1 off) then applies,
mirroring the Table 3 zero-primary-loss gate already present for WHC 903.
General bug — fires for any WHC-903 dwelling whose space main is a PCDB gas/oil
boiler. It surfaced via the PasHub campaign's #1600 no-water-heating default
(WHC 999 -> 903) on a gas-combi dwelling: 58 Hackle St M11 4WU, SAP 55.30 ->
57.67 (pre_sap 58, verified 59).
Guardrails: the gov-API RdSAP corpus IMPROVES 78.8% -> 78.9% within-0.5, MAE
0.625 -> 0.622 (a handful of corpus certs with a boiler space main + electric
immersion move closer to accredited) — MAE ceiling ratcheted 0.626 -> 0.625.
Regression pinned in test_cert_to_inputs (RED before / GREEN after). pyright
0-new (cert_to_inputs baseline 30).

* PasHub SAP accuracy: thread low-energy lights + draught lobby (from_site_notes) 🟩
Two systematic silent-drops in the PAS Hub `from_site_notes` path, each a field
the gov-API/Elmhurst mappers thread but site-notes dropped, letting a favourable
default reach the SAP-10.2 calculator. Validated against the correct pashub
oracle (property_baseline_performance.effective_sap_score, portfolio 838):
cohort within-0.5 55.1% → 62.6%, MAE 0.599 → 0.521.
- Low-energy lights: when "exact LED/CFL known = No", PAS Hub lodges an aggregate
"Number of fixed low energy lights?" count. Previously dropped (no dataclass
field / extractor key / mapper thread) → calculator saw 0 low-energy bulbs and
applied the pessimistic L5b/L8c no-data default, under-rating SAP. Now threaded
into low_energy_fixed_lighting_bulbs_count, mirroring from_elmhurst_site_notes.
~6% of the cohort; resolves 58 Hackle (−0.43 vs oracle 59 with #1615).
- Draught lobby: _map_sap_ventilation set only the legacy `draught_lobby` field,
never the canonical `has_draught_lobby` §2 (13) gate the cascade reads, so the
surveyed lobby was ignored and infiltration over-stated. Now mirrors Elmhurst.
Two other audited levers were REJECTED against the pashub oracle (they matched
the gov-cert/RdSAP convention but pashub does not apply them): percent_draughtproofed
(cohort 30.8%) and the §A.2.2 assumed secondary heater (19.2%). A heat-network
control-code fix (2306→2303 for 16 Bingley) is HELD pending spec/Elmhurst
adjudication — it contradicts ADR-0053; see the NOTE on _PASHUB_HEAT_NETWORK_CONTROL_TO_SAP10.

* PasHub heat-network control: room-thermostat-only maps to 2308, not 2306 🟩
The Table 4e Group 3 label "charging linked to use of community heating, room
thermostat only" was mapped to 2306 — the linked-to-use *with-TRVs* code
(control type 3, space charging 1.00). The label explicitly excludes TRVs, so
it is control type 2 / space 1.05 = code 2308/2309 (linked-to-use → DHW 1.00).
2306 asserted TRVs the survey doesn't have and over-rated the cohort's sole
heat-network dwelling (16 Bingley Close 56.89 → 54.01 vs pashub oracle 52).
Verified against SAP 10.2 Table 4e as encoded in cert_to_inputs.py
(_CONTROL_TYPE_BY_CODE 2308→2, space-charging 2308→1.05, DHW 2308→1.00) and the
RdSAP control-label vocabulary in MainheatControlAttributes.py. 2303 (the earlier
audit's guess) is rejected: it is a flat-rate code (DHW 1.05) whose oracle match
was a coincidence of two offsetting spec violations. The residual +2.0 to oracle
52 is the documented SAP-10.2-engine-vs-lodged offset, not a fuel/flags gap
(those were threaded by the #1590 follow-up) — supersedes the ADR-0053 /
HANDOVER_838 "community fuel/flags" attribution.
16 Bingley is the only heat-network fixture in portfolio 838, so this moves one
fixture strictly toward its oracle. Harness ratcheted: within-0.5 0.51→0.58,
MAE 0.625→0.521 (observed 58.5% / 0.520 with all three 2026-07-15 levers).

* PasHub SAP accuracy: restore 3 dropped §2 infiltration inputs (from_site_notes)
`from_site_notes` uniquely dropped three ventilation inputs that the gov-API
and Elmhurst sibling mappers all set, causing a systematic cohort-wide SAP
under-rate vs the company's own accredited SAP-10.2 certs
(property_baseline_performance.effective_sap_score, portfolio 838):
1. percent_draughtproofed — never set, so §2(15) window infiltration was
pinned at its 0.25-ACH worst case on every dwelling. Reconstructed as the
area-weighted % of draught-proofed windows (mirrors Elmhurst
`draught_proofing_percent`). Dominant term.
2. Upper-storey +0.25 m joist void — omitted; now added, matching
`_UPPER_FLOOR_HEIGHT_ADD_M` on the gov-API/Elmhurst paths. This
RE-ADJUDICATES #1601 ("keep raw"): that call was confounded by the
then-present draught-proofing drop suppressing every verified dwelling.
3. sheltered_sides — left None → calculator's flat default of 2, which
over-shelters end/semi/detached (RdSAP §S5 = 1/1/0). Now derived from
built form.
The three are NON-ADDITIVE — each overshoots alone (which is why all three
were previously rejected individually) — but together they land all 7
verified ground-truth dwellings toward truth (none regress) and every built
form near zero. Cohort 62.1% -> 83.3% within-0.5, MAE 0.507 -> 0.377.
Guardrails: gov-API RdSAP corpus unchanged (78.9%, these are from_site_notes-
only helpers). pashub harness 58.5% -> 79.5% / MAE 0.520 -> 0.389; ratchets
tightened 0.58->0.78 and 0.521->0.40. pyright zero-new (mapper baseline 39).
New focused tests in TestFromSiteNotesInfiltrationFixes cover all three
fields incl. area-weighting and the built-form shelter map; goldens updated.

Resolve#1601 and land #1602/#1603 on the merged-#1609 tree, adjudicated
against Khalim's verified ground truth (not pre_sap).
#1601 (upper-floor +0.25 m joist void) — RESOLVED as keep-raw. The
gov-API/Elmhurst mappers add 0.25 m to upper-storey heights because their
lodged height is a clear internal ceiling. Against verified truth RAW beats
+0.25 on all 7 verified dwellings (16 Stillwater raw -0.35 within-band vs
+0.25 -0.75; every verified property is already under truth and +0.25 only
lowers SAP). pashub surveys internal dimensions (202/205 "Measurements
Location: Internal") and its upper-ground height gap is modal 0.00, so the
joist void is not differentially present and a blanket +0.25 is unsafe.
_map_floor_dimensions keeps the raw surveyed height with a RESOLVED note.
#1602 — semi-exposed / exposed floor exposure. The surveyed "Floor type"
"Semi Exposed (unheated)" now sets is_above_partially_heated_space (RdSAP
§5.14 U=0.7) and "Exposed Floor" sets is_exposed_floor (§5.13 Table 20), on
the lowest storey (floor==0) only, mirroring the gov-API/Elmhurst siblings.
New strict-raise _pashub_floor_exposure (ADR-0015).
#1603a — alternative walls. New AlternativeWall survey dataclass +
extract_alternative_walls (the "Alternative Wall"->"Windows" section) +
_map_pashub_alternative_walls -> sap_alternative_wall_1/2. The cascade
deducts each alt-wall area from the part's main opaque wall (no double
count), so a mixed-facade dwelling is billed at each sub-area's own
construction. The alt-wall block lodges "As Built" (capital B) — aliased to
the existing default insulation code.
#1603b — extension floor construction. ExtensionConstruction gains a floor
block (parsed like the main building) and _map_extension_building_part now
threads floor_type/construction/insulation/u_value_known, which the main
path already did and the extension silently dropped.
Cohort: within-0.5 50.2% -> 51.2%, MAE 0.652 -> 0.624, 0 strict-raise
errors across all 205. Verified-truth safe: none of the 7 verified
dwellings have alt walls, and #1602 moves the one it touches (2 Philips
exposed ext floor) by -0.00. pyright 0-new (mapper baseline 39). Goldens
test_full_building_construction + end_to_end EXTENSION_1 updated.

Three silent-drop extraction fixes the gov-API/Elmhurst mappers already apply
but `from_site_notes` uniquely omitted — each let a favorable default reach the
SAP-10.2 calculator and over-rate the dwelling. Same calculator, so the whole
gap was extraction fidelity (gov-API corpus 78.6% within-0.5 vs pashub 23.9%).
#1598 — electric-shower + bath counts: `_map_sap_heating` built `shower_outlets`
but never set `electric_shower_count`/`mixer_shower_count`/`number_baths`, so
the cascade defaulted to 1 gas mixer / 0 electric, billing electric-shower hot
water off the cheap main system. 100/205 fixtures lodge "Electric Shower".
#1599 — floor label: pashub lodges "Ground Floor" (capital F); the calculator's
RdSAP §5(12) suspended-timber floor-infiltration gate is case-sensitive on
"Ground floor", so the 0.2-ACH term was silently dropped. Normalized at the
mapper boundary. 98/205 suspended-timber.
#1600 — water-heating "None": the RdSAP 10 §10.7 "no water heating system"
signal was discarded and HW inherited the gas combi (58 Hackle 67.7 vs
verified 59). Coded to WHC 999 so the existing electric-immersion + Table
28/29 default fires (also folds in #1594: blank cylinder size is no cylinder,
not a phantom one).
Guinness GMCA 205 cohort: within-0.5 23.9% -> 50.2% (103/205), MAE 1.410 ->
0.650. Ratchets tightened to 0.50 / 0.65. Verified vs Khalim's ground truth
(16 Stillwater 78.2 -> 75.7 vs 76). #1601 (upper-floor +0.25 m) held — it
empirically over-corrects this cohort (internal-vs-external dimension question,
under investigation). pyright: 0 new errors.

Second sanctioned exception to "ratchets never loosen" — needs @KhalimCK's
call, since the prior note expected to re-tighten here. Exactly one cohort
property is WHC 950 (16 Bingley Close, +5.946 -> +6.818 = the whole +0.0043);
within-0.5 unchanged at 23.9%. Its pre_sap is verified correct but its ~+6
residual is a known extraction bug, and this hybrid gauge cannot adjudicate a
calculator fix (#1592 Problem 2). The gov-API corpus, which gauges the
calculator alone, improves.
