ModellingOrchestrator builds the ventilation dependency per Property
(suppressed when already mechanically ventilated) and passes it to
optimise_package, so a selected wall measure forces MEV into the package before
the re-score. Ventilation joins the role-3 cascade in best-practice order
(walls -> roof -> ventilation -> floor) and persists as a Plan Measure carrying
its real negative marginal and its cost. Added the mechanical_ventilation
contingency rate (0.26, per legacy Costs.CONTINGENCIES). Integration test now
seeds the ventilation Product and asserts the forced measure persists with
<=0 SAP and 2x900 cost; the full-pipeline test seeds the Product too (the
dependency is built for every not-yet-ventilated dwelling). On 000490 the real
calculator scores MEV at -1.275 SAP.

ventilation_dependency(epc, products) returns the forced 'fabric requires
ventilation' edge: triggers = MEASURES_NEEDING_VENTILATION (cavity/internal/
external wall, mirroring legacy assumptions.measures_needing_ventilation), and a
required Option installing decentralised MEV (mechanical_ventilation_kind=
EXTRACT_OR_PIV_OUTSIDE), priced at two fully-loaded units. Returns None when the
dwelling already lodges a mechanical ventilation kind (legacy has_ventilation
guard), so MEV is never forced onto an already-ventilated dwelling.

MeasureDependency(triggers, required) is a data-declared 'A requires B' edge.
optimise_package gains a dependencies param: after the warm-start it injects any
dependency whose triggers intersect the selected measure-types, BEFORE the
whole-package re-score, so the dependency's (negative) SAP lands in the truthful
figure and the undershoot/repair decision (ADR-0016). Forced — injected
regardless of budget — but its cost counts toward package spend, so repair sees
less headroom. Repair candidates fold in any dependency they newly trigger, so
their marginal SAP-per-£ and incremental cost are truthful. The dependency never
competes in the optimiser pool. Returned selected includes the injected deps.

Captures the session's window/RR/dual-main work (S0380.196–200) and the
open priority: a spec-accurate per-system boiler-interlock −5pp (Table
4c(2)) adjustment. Root cause for case 6's remaining deltas (sys-1 eff 79
not 84 + HW 4824 vs 4902) is the "room thermostat present but no cylinder
thermostat → no interlock" path that the current {2101,2102} no-interlock
rule misses. 0240 shares the controls + cylinder_thermostat=N so it will
re-pin (apply spec uniformly). Secondary: dual-system Table 4f pumps.

The cascade lumped a dwelling with two main heating systems into one:
`space_heating_fuel_monthly_kwh` hard-coded (203)=0 (a documented
scope-A placeholder) and the calculator's per-month fuel read only
main_1, so the full §8 space-heat demand billed against system 1's
efficiency. Simulated case 6 (one oil boiler feeding radiators 51% +
underfloor 49%) exposed it: main fuel ≈ demand/eff1 instead of the
worksheet's (211)+(213) per-system split.
Implements the SAP 10.2 §9a two-main model:
(204) = (202) × (1 − (203)) → system 1 share of total heat
(205) = (202) × (203) → system 2 share of total heat
(211)m = (98c)m × (204) × 100 / (206)
(213)m = (98c)m × (205) × 100 / (207)
(203) = the second system's lodged `main_heating_fraction`; (207) = its
own seasonal efficiency via the new per-detail `_main_heating_detail_
efficiency` (the core of `_main_heating_efficiency`, now reused for
system 2). Calculator `_solve_month` aggregates main_1 + main_2 into
`main_heating_fuel_kwh`. Cost (§10a 241), CO2 (§12 262) and PE (§13 276)
main_2 paths were already wired and now activate.
Site-notes gap also fixed: §14.1 Main Heating2 omits the "Fuel Type"
cell when the second system shares Main 1's fuel (case 6: one oil boiler,
two emitters). `_map_elmhurst_main_heating_2` now inherits Main 1's
resolved fuel as a fallback.
Blast radius: only dual-main certs. 0240 (2× oil code 130, identical
Eq-D1 efficiency) is unchanged — its split collapses to the lumped total.
Suite: 2355 passed, 1 skipped. New code: 0 pyright errors.
NOTE: case 6 is not yet fully pinnable end-to-end — its two systems have
DIFFERENT efficiencies (radiators 55°C → 79%, underfloor 35°C → 84%), a
flow-temperature boiler-efficiency adjustment not yet modelled, and its
dual-system auxiliary pumps ((230c)+(230d)=356) differ from the cascade.
Both are separate follow-on features; this slice is the §9a fuel split.

Slice 3b — closes#1160. ModellingOrchestrator._plan_for now runs the
full ADR-0016 flow instead of a single cavity measure:
generate wall + roof + floor Recommendations → score each Option
independently (role 1) into grouped ScoredOptions → optimise_package
(grouped knapsack within budget + whole-package re-score + greedy
repair toward the Scenario's SAP target) → attribute the selected set
via the best-practice marginal cascade (role 3) → persist the Plan
with its Plan Measures.
The repair target comes from the goal: INCREASING_EPC → the goal_value
band floor via Epc.sap_lower_bound(); other goals carry no SAP target
yet (later slice). Best-practice order walls → roof → floor.
Integration test: an uninsulated cavity wall + suspended floor (000490)
driven directly through the Modelling stage off a repo-seeded EPC
(the calculator fixture has no lodged recorded-performance fields, so
Baseline can't run it) persists a Plan with two attributed, priced Plan
Measures. The existing first-run test keeps full-pipeline coverage and
now exercises real modelling (its sample EPC's uninsulated solid floor
yields a floor measure). Replaces the single-measure cavity integration
test (subsumed). 138 pass; pyright strict clean.
Multi-phase remains descoped (ADR-0005); single-phase optimiser.

The Elmhurst extractor crashed parsing simulated-case-6's room-in-roof
window rows: the §11 "Location" cell "Roof of Room in Roof" wraps across
the layout prefix/suffix blocks and leaked into the glazing-type phrase
("Double between 2002 Roof of Room and 2021 in Roof" → UnmappedElmhurst-
Label). Fix (`_parse_window_from_anchors`): detect the roof-of-room
location tokens, strip them from the before/after blocks so the glazing
phrase reconstructs cleanly, and set location="Roof of Room".
Mapper: `_is_elmhurst_roof_window` gains a "Roof of Room" location branch
(highest-confidence rooflight signal, above the BP-roof-type / U>3.0
gates); `_ELMHURST_ROOF_WINDOW_U_BY_GLAZING` gains "Double between 2002
and 2021" → 2.30 (case 6 lodges the already-inclined roof-window U, so
the +0.30 inclination adjustment must not double-apply).
This is the site-notes mirror of S0380.198 (API window_wall_type=4):
both paths now route room-in-roof rooflights to (27a) at the inclined U.
Validated against the case-6 P960 worksheet at abs=1e-4:
(27) Windows = 22.7408 (cascade 22.7407)
(27a) Roof Windows = 13.0375 (cascade 13.0375, EXACT)
(31) ext area = 336.13
Case 6 is pinned only on the §3 window line refs (new standalone test,
not added to the section-pin `_FIXTURES`) because its DUAL main heating
(51% rads + 49% underfloor, oil) makes the §10/§12 per-system lines
non-comparable to SapResult's aggregated fields — documented in the
fixture module. Summary mirrored to Summary_001431_case6.pdf.

Slice 2 of #1160 — the ADR-0016 truth step on top of the warm-start
knapsack. optimise_package(groups, scorer, baseline_epc, budget,
target_sap) -> OptimisedPackage:
warm-start optimise() (role-1 signal) → re-score the chosen package on
the real scorer (role-2 truth) → while the true SAP undershoots
target_sap and budget remains, greedy-add the untreated-group Option
with the best *marginal* SAP-per-£ (re-scored, not the role-1 signal),
re-score, repeat until the target is met, nothing positive-marginal is
affordable, or the budget is spent.
`Scorer` is a structural Protocol (PackageScorer satisfies it) so the
repair loop is tested with a stub scorer — no calculator, runs on ARM.
The key case: role-1 under-counts roof so the warm-start skips it, the
re-score undershoots, and repair adds roof back to hit the target. 3
repair tests + the 6 core tests; pyright strict clean.

Slice 1 of #1160. Recycles the GainOptimiser/CostOptimiser formulation
(≤1 Option per Recommendation, maximise SAP gain subject to budget) as a
clean typed DDD function — but as an exact pure-Python multiple-choice
knapsack rather than the legacy `mip` MILP, since mip's CBC backend does
not load on aarch64 (so the legacy solver path can't run / be tested
here). At retrofit scale the candidate space Π(|group|+1) is tiny, so
exhaustive enumeration is exact and instant; ADR-0016 only needs the
knapsack as a warm-start signal anyway (the truthful figure comes from
the whole-package re-score + repair, next slice).
`optimise(groups, budget) -> list[ScoredOption]`: maximise total gain,
tie-break toward lower cost, skip-per-group covers "select none". 6 tests

Cert 0240's SAP residual (-1) and a chunk of its PE/CO2 was an API-mapper
bug: it flattened ALL windows into sap_windows, so the 6 windows lodged
with window_wall_type=4 — the RdSAP code for a roof window ("Roof of Room"
rooflight / inclined glazing) — were billed as vertical wall glazing on
worksheet (27) at U=2.0, instead of roof windows on (27a) at the Table 6e
Note 2 inclination-adjusted U (DG 2002+ vertical 2.0 + 0.30 = 2.30) with
45°-inclined solar gains.
window_wall_type=4 is the discriminator, NOT window_type=2 (certs 0390 /
7536 lodge window_type=2 on ordinary main-wall windows). Fix: partition
the 21.0.1 API window list into sap_windows (wall_type≠4) + sap_roof_
windows (wall_type=4); `_api_sap_roof_window` mirrors the site-notes
`_map_elmhurst_roof_window` (vertical U from the glazing Table-24 lookup +
0.30 inclination; 45° pitch; g/FF from the same lookup).
Validated against the simulated-case-6 worksheet, which bills these
identical windows on (27a) at U_eff 2.1062 (= 2.30 with the §3.2 R=0.04
curtain transform). The inclined solar gain dominates the higher U-loss,
RAISING the SAP:
- 0240: SAP cont 72.14 → 72.55 (resid -1 → +0 EXACT), PE +3.91 → +1.95,
CO2 +0.22 → +0.12
- 6035: 2 wall_type=4 rooflights — SAP still +0 exact, PE +1.84 → +1.37,
CO2 +0.01 → -0.0004
Blast radius is exactly these two certs (only golden fixtures with
wall_type=4). Suite: 2354 passed, 1 skipped. New code: 0 pyright errors.

Measure (priced from the Product, figures present, linked by plan_id).
Numeric SAP correctness is pinned separately in test_elmhurst_cascade_pins.

Promotes user-simulated "case 5" (detached, sandstone-walled, room-in-roof
cousin of golden cert 0240) to an e2e worksheet fixture pinning the WHOLE
extractor → mapper → calculator pipeline at abs=1e-4 on all 11 Block-1
line refs. Its worksheet prints the exact RR-gable routing S0380.196
implements, validating that fix against ground truth:
Roof room Main Gable Wall 1 15.68 U=0.35 (29a) Exposed → walls @ main-wall U
Roof room Main remaining area 61.73 U=0.30 (30) A_RR shell − Σ gables
External roof Main 14.52 U=0.11 (30) loft residual
Roof room Main Gable Wall 2 15.68 U=0.25 (32) Party → party @ 0.25
gable area = 6.40 × 2.45 (§3.9.1 default RR storey height); A_RR remaining
= 12.5√(83.2/1.5) − 2×15.68 = 93.09 − 31.36 = 61.73 (RdSAP 10 §3.9.1(e)).
Confirms a DETACHED dwelling can lodge a Party RR gable (Table 4 p.22
row 2) — so my S0380.196 mapping (gable_wall_type 0=Party, 1=Exposed) is
correct; do not flip it.
Two extractor/mapper gaps surfaced and fixed (case 5 is the forcing test):
- Sandstone wall label "SS Stone: sandstone or limestone" had no
`_ELMHURST_WALL_CODE_TO_SAP10` entry (raised UnmappedElmhurstLabel).
Added "SS" → 2 (WALL_STONE_SANDSTONE), matching 0240's API
wall_construction=2 (cross-mapper parity).
- Roof "Insulation Thickness 400+ mm" was silently dropped: the four
thickness parsers used `.split()[0].isdigit()`, which rejects the
trailing "+" → None → u_roof fell back to the age-J default 0.16
instead of 0.11 (+1.09 W/K roof, the whole 0.12 SAP gap). Added
`_parse_thickness_mm` (strips to leading digits) and applied it at all
four sites (walls / alt-wall / roof / floor). The only existing fixture
with "400+ mm" (000565 Stud Wall) routes via the RIR regex, unaffected.
Result: case 5 cascade ≡ worksheet at 1e-4 on SAP/ECF/cost/CO2 + every
energy stream. Neither gap affects 0240 (its API path captures both the
sandstone code and "400mm+"); 0240's residual is therefore non-fabric.

Slice 1 of the #1157 build. The FE creates a Scenario and passes only
its id to the pipeline; the Modelling stage reads it back here.
- domain/modelling/scenario.py: thin `Scenario(id, goal, goal_value,

- infrastructure/postgres/scenario_table.py: `ScenarioRow` SQLModel
mirror of the live `scenario` table (ADR-0017), declaring only the
read columns; goal mapped as its string value.
- ScenarioPostgresRepository.get_many(scenario_ids) -> list[Scenario]:
bulk read, input-order-preserving, raises on a missing id.

Outcome of the /grill-with-docs session scoping #1157.
- CONTEXT.md: add **Plan Measure** (the persisted selected Option +
role-3 attribution + cost); Recommendation stays the candidate.
Remove Scenario Phase / Plan Phase / Rolled-over Options — multi-phase
is deferred. Reshape Scenario + Plan to single-phase; fix relationships,
dialogue, and the "phase" ambiguity note.
- ADR-0005: rewritten to Deferred (multi-phase was speculative
prospective-client work; single-phase now; future plan_phase back-fill
path preserved). Stray phase refs cleaned in ADR-0016 / ADR-0009.
- ADR-0017 (new): Plan persistence — reuse the live plan/recommendation
tables via SQLModel mirrors + a PlanRepository on the UoW; add
recommendation.plan_id, retire the plan_recommendations m2m; flat
post-retrofit on plan; idempotent replace; CO2 in tonnes. Unselected
alternatives + bills noted as deferred directions.

Golden cert 6035's residual (SAP -2 / PE +19.16 / CO2 +0.42t) was a real
API-mapper bug, NOT lodged divergence (prior claim retracted).
The API `room_in_roof_type_1` block lodges gable walls by length only (no
height). The mapper carried just the scalar `gable_*_length_m`, and the
cascade's `_part_geometry` gable formula silently drops height-less gables
(needs a height) -> the whole A_RR shell `12.5√(A_RR_floor/1.5)` billed as
roof at U_RR=2.30 instead of the §3.9.1(e) residual
`A_RR − Σ gables`. On 6035 that over-counted roof by 22.78 m² × 2.30 =
+52.4 W/K (roof 130.73 -> 78.33, matching the site-notes case-4 replica at
1e-4 — cross-mapper parity).
RdSAP 10 §3.9.1(e) (PDF p.21): "the area of the room-in-roof gable walls
... is deducted from A_RR to give the residual roof area." Fix: route the
Type 1 gables through `detailed_surfaces` (gable area = L × the §3.9.1
default RR storey height 2.45 m; gable_wall_type 0=Party->gable_wall U=0.25,
1=Exposed->gable_wall_external "as common wall" per Table 4 p.22) so the
cascade's Detailed-RR residual fires — the same path the site-notes mapper
already uses.
Re-pinned golden residuals:
- 6035: SAP -2 -> +0 (exact), PE +19.16 -> +1.84, CO2 +0.42 -> +0.01
- 0240: same fix applies (2 Party gables L=6.4); PE +5.80 -> +3.91,
CO2 +0.32 -> +0.22, SAP integer unchanged
Also corrected the stale "gable_wall_type 0 = external" schema comment
(6035's Summary proves 0=Party, 1=Exposed) and added a strict
UnmappedApiCode raise for unknown gable_wall_type codes.

Retracts the premature "6035 = lodged divergence" claim (S0380.195 commit
msg + fixture docstring). The golden residual SAP -2 / PE +19.16 / CO2
+0.42t is REAL and exceeds the fallback bar. Section-level diff of 6035
(API) vs sim case 4 (site-notes, pins @1e-4) localised it to a
cross-mapper parity break: roof W/K 78.33 (site-notes) vs 130.73 (API),
a +52 over-count from the API RR scalar path + roof_construction=4. Next
agent starts there.

Adds the user-simulated case-4 worksheet as e2e fixture `001431_6035` —
reproduces golden cert 6035's full floor geometry (Main ground-floor HLP
15.99 + first-floor HLP 8.32, the asymmetric upper storey) and 8 windows.
All 11 Block-1 line refs pin at abs=1e-4 against the worksheet (SAP 68,
ECF 2.2802, cost 937.2341, CO2 4682.3494, space 15745.3260, main fuel
18744.4357).
This is the 4th independent 1e-4 confirmation across the 6035 archetype
(sim cases 1-4). Case 4 matches 6035 on floors + window areas; the
residual ~50 kWh / £11 cascade delta vs 6035 is two lodged inputs only
(largest window orientation N vs S; meter type "Dual" vs API 2), not
calculator behaviour.
Conclusion: the cascade reproduces the spec engine exactly for 6035's
geometry, so 6035's +19 PE vs the lodged register is lodged-register
divergence (the gov.uk register's rounded value vs the spec-exact
worksheet), NOT a calculator gap. 6035 is a "pin-forever" lodged-only
cert. Bugs surfaced + fixed along the way: S0380.192 (Simplified-RR
remaining area) and S0380.193 (suspended-floor sealed rule).

Adds the file-backed Product catalogue — the stopgap source for costs
the ETL does not yet supply, behind the same ProductRepository port as
ProductPostgresRepository. The JSON file maps each Measure Type to its
fully-loaded unit cost; the per-Measure-Type contingency is joined from
config (not stored in the file), so config stays the single source of
truth for contingency — mirroring the Postgres repo's mapping.
Strict-raises (ValueError) on an absent measure type, a non-object
entry, or a missing/non-numeric unit_cost_per_m2, matching the
repo-wide strict-no-silent-default convention. tmp_path-backed tests,

Adds the user-simulated case-3 worksheet as e2e fixture `001431_rr8` —
Main + Extension + Simplified room-in-roof with 8 windows (≈14.15 m²,
reproducing golden cert 6035's glazing) and Main ground-floor HLP 15.99.
All 11 Block-1 line refs pin at abs=1e-4 against the worksheet (SAP 68,
cost 951.3425, CO2 4767.4862, space 16086.3557, main fuel 19150.4235,
HW 3307.2639, lighting 262.0885).
This is the third independent 1e-4 confirmation that the cascade
reproduces the spec engine for the 6035 archetype (after S0380.192

input only — the Main first-floor HLP (15.99 here vs 6035's 8.32) — so
6035's +19 PE vs the lodged register is lodged-register divergence, not
a calculator gap. A byte-identical 6035 replica (first-floor HLP 8.32)
would let 6035 itself be pinned directly to close that out.

Records that the Elmhurst recommendation Summaries parse via the
extractor chain (not parse_site_notes_pdf), so the "parser gate" never
blocked the cascade pins. All four pins close at delta 0; loft 270→300
and the suspended-floor insulation-type field were the two gaps fixed.
Remaining: #1157 (HITL schema review) + ProductJsonRepository.

Completes #1159 end-to-end with solid and suspended-floor before/after
cascade pins on cert 001431, both closing at delta 0.000000.
Adds floor_insulation_type_str to BuildingPartOverlay (the generic
field-fold applicator picks it up with no change) and has
recommend_floor_insulation set it to "Retro-fitted". Insulating an
as-built floor re-lodges its insulation as retro-fitted; the calculator
keys on this for a suspended timber floor's sealed/unsealed
determination (cert_to_inputs.py: "retro" + no U-value supplied →
sealed). Without it the suspended-floor cascade left a +1.40 SAP gap
(the floor stayed "unsealed", wrong U-value); with it the cascade
closes exactly. Solid floors are unaffected by the seal logic and stay
at delta 0; both Elmhurst after-certs lodge "Retro-fitted", so setting
it uniformly is faithful.

Completes #1158 end-to-end. recommend_loft_insulation now emits a
300 mm overlay (was 270 mm). The Elmhurst before/after re-lodgement of
the loft-insulation measure on cert 001431 lodges the after-cert at
300 mm roof insulation; pinning before→overlay→after requires the
overlay to match that depth — at 270 mm the cascade left a +0.173 SAP
residual, at 300 mm it closes at delta 0.000000 on SAP/CO2/PE.
Adds test_loft_overlay_reproduces_the_relodged_after and updates the
roof generator unit test's thickness assertion to 300.

Closes#1154 — the Package Scorer's Elmhurst cascade pin. Drives
recommend_cavity_wall on the parsed `before` Summary, scores its
Option's overlay through PackageScorer, and asserts delta 0 (abs<=1e-4
on SAP/CO2/PE) vs the calculator's score on the re-lodged `after`
Summary.
Key finding: the handover's stated parser gate (parse_site_notes_pdf
throwing 'Manufacturer' on cert 001431) does NOT block these pins. The
Elmhurst recommendation Summaries route cleanly through the same
ElmhurstSiteNotesExtractor + EpcPropertyDataMapper chain the worksheet
e2e fixtures use (_elmhurst_worksheet_001431.build_epc). The Textract
path's window bug is unrelated and unused here.
The before→after field change is exactly wall_insulation_type 4
(uninsulated) → 2 (filled cavity), which is precisely the overlay
recommend_cavity_wall emits; the cascade closes at delta 0.000000 on
all three metrics. Before/after Summaries mirrored into
tests/domain/modelling/fixtures/ so the pin does not depend on the
unstaged workspace.

RdSAP 10 §5 (PDF p.29) "Floor infiltration (suspended timber ground
floor only)", age band A-E, splits on whether a floor U-value is
supplied:
a) [U-value supplied] if floor U-value < 0.5 → "sealed", (12) = 0.1
b) [no U-value supplied] retro-fitted insulation → "sealed" 0.1;
otherwise "unsealed", (12) = 0.2
`_has_suspended_timber_floor_per_spec` fed the cascade's COMPUTED default
U into rule (a), so an as-built/uninsulated suspended-timber floor whose
default U happens to be < 0.5 was marked "sealed" (0.1) where Elmhurst
uses "unsealed" (0.2). That dropped (18) infiltration 0.85 → 0.75, (25)
effective ACH, HTC, and understated space heating ~450 kWh.
Fix: gate rule (a) on `floor_u_value_known` — a computed default U is not
a supplied value, so it falls through to (b). Verified against the
cert 001431 sim-case-2 worksheet: floor "As built", U=0.43 (matches the
worksheet's (28a) 0.4300 exactly), (12)=0.2 unsealed. Golden cert 6035
(also a suspended uninsulated floor) is unaffected — its U=0.63 ≥ 0.5
already routed to unsealed.

recommend_floor_insulation(epc, products) detects an uninsulated ground floor

from floor_construction_type — 'Suspended timber' -> suspended_floor_insulation,

recommend_loft_insulation(epc, products) detects an uninsulated main loft

- building_geometry.roof_area(epc, identifier): the part's greatest
per-storey floor area (RdSAP 10 §3.8). Pinned 14.85 m^2 on 000490 MAIN.

Applicator writes it with NO change (validated by the tracer) — the
deep-module field-fold paying off.

A Simplified room-in-roof (RdSAP 10 §3.9.1, PDF p.21) does NOT measure
its slope / flat-ceiling / stud-wall surfaces — the Elmhurst Summary
lodges placeholder Length/Height cells (a 40 m flat-ceiling height, a
32 m slope on a 4.65 m-wide gable). The spec instead derives one
timber-framed "remaining area" from the floor area:
A_RR = 12.5 × √(A_RR_floor / 1.5) §3.9.1(d)
A_RR_final = A_RR − ΣA_RR_gable/other §3.9.1(e)
The cascade already computes A_RR_final itself (heat_transmission.py:
`12.5 × √(A_RR_floor/1.5) − rr_walls_in_a_rr_area` residual), but only
when `detailed_surfaces` carries no roof-going kind (`has_roof_lodgement`
gate). `_map_elmhurst_rir_surface` emitted the placeholder slope/ceiling
rows as raw L×H for every assessment type, flipping that gate and billing
1024 m² + 160 m² of explicit roof area — a 7.5× fabric-heat-loss
explosion (cert 001431 sim case 2: SAP −14.6 vs worksheet 69, space
heating 114 378 vs ~15 000 kWh).
Fix: for a Simplified assessment, drop the roof-going surfaces in the
mapper so the cascade's residual formula fires. This matches how the API
path already (correctly) handles the same Simplified RR — scalar gable
fields, no roof-going detailed_surfaces (golden cert 6035) — and the
gables-only cert 000565. Detailed (§3.10) assessments still measure these
surfaces and keep them.
With the fix, sim case 2 total external area = 232.94 (worksheet exact),
roof 78.33 (was 2725.89), SAP 69.29 → worksheet integer 69. A small
residual (~450 kWh main fuel) remains — a separate fabric gap to walk
next. 2308 passed (+2), 0 failed; pyright net-zero.

scoring.py adds the telescoping marginal cascade that serves two of the three
ADR-0016 scoring roles:
- marginal_impacts(scorer, baseline, overlays): applies overlays cumulatively
in order and reports each measure's marginal MeasureImpact (sap_points +
carbon/energy savings). Role 3 (final-package attribution) — the marginals
telescope EXACTLY to the whole-package total.
- independent_option_impacts(scorer, baseline, options): role 1 — scores each
Option's overlay independently vs baseline, scoring each DISTINCT overlay
once (Options sharing an overlay reuse the result). Approximate signal for
the optimiser; never surfaced as a measure's true impact.
Role 2 (whole-package re-score) is PackageScorer.score directly. Three
behaviour tests on the real Sap10Calculator / a counting stand-in (hand-built
EPD): single-overlay marginal == improvement-over-baseline; two-overlay
marginals telescope to the package total; per-Option dedup scores each
distinct overlay once. Closes#1156. pyright strict clean.

PackageScorer(calculator: SapCalculator).score(baseline, simulations) folds
the Simulation Overlays onto the baseline via the Overlay Applicator and
scores the throwaway EpcPropertyData on the injected deterministic SAP
calculator, returning Score(sap_continuous, co2_kg_per_yr,
primary_energy_kwh_per_yr). Depends on the SapCalculator abstraction, not a
concrete engine. This is the reusable scoring primitive (ADR-0016) — the
same call serves the optimiser's whole-package re-score and a future live
re-score of a user-assembled plan.
Two behaviour tests against the real Sap10Calculator on a hand-built EPD:
filling the main cavity improves SAP (right-directional through the real
physics); an empty package scores the unmodified baseline (pins the
SapResult->Score mapping). The Elmhurst before/after cascade PIN (#1154's
acceptance) lands once cert 001431 parses (external _extract_windows fix).

recommend_cavity_wall now takes a ProductRepository and prices the Measure
Option: Cost(total = gross_heat_loss_wall_area(MAIN) x product.unit_cost_per_m2,
contingency_rate = product.contingency_rate). Detection is unchanged and runs
before pricing, so ineligible walls still return None without a catalogue hit.
Completes #1155 — the cavity-wall Recommendation Generator now detects an
uninsulated main cavity wall and emits a priced Option carrying the filled-
cavity overlay. Four behaviour tests (detection x3 + fully-loaded cost).

Product(measure_type, unit_cost_per_m2, contingency_rate). ProductRepository
is the DDD port abstracting the catalogue source; ProductPostgresRepository
reads the externally-owned material table (defensive SQLModel view
MaterialRow) and maps an active row to a Product — total_cost becomes the
fully-loaded unit_cost_per_m2 — joining the per-measure-type contingency
(contingencies.py, mirrors Costs.CONTINGENCIES; cavity 0.10). Strict-raise
on missing/inactive row. A JSON-backed impl will follow behind the same
port for ETL-gap costs.
Two DB tests against an ephemeral Postgres (map active row; raise on
inactive-only). Toward #1155 cost (4b). Also generalises the CONTEXT
Simulation Overlay wording: windows are targeted by index, building-part
association carried via window_location (_window_bp_index). pyright clean.

Summary PDFs preprocessed from `pdftotext -layout` wrap the windows-table
header across several lines. The third header line's tail ("U value / g
value / Draught Proofed / Permanent Shutters") tokenises to "value value
Proofed Shutters" and lands directly above the FIRST window's data row.
Because the first window in a building part has `before_start = 0`, its
prefix block reaches back into that header remnant. The remnant is
neither an orientation nor a building-part fragment, so it survived the
pops in `_compose_window_descriptors` and leaked into glazing_type as
"value value Proofed Shutters Double between 2002 and 2021" (windows 2-3,
whose prefix starts after the previous window's manufacturer line, were
clean).
Fix: the glazing-type phrase always starts with a glazing-start word
(Single/Double/Triple/Secondary), so trim any prefix fragments preceding
that word before joining the glazing type. Orientation/bp pops still run
on the full prefix, so they are unaffected.
Reproduced from `sap worksheets/Recommendations Elmhurst Files/
cavity_wall_insulation - main wall/before/Summary_001431.pdf`. Added a
regression test driving the real `_extract_windows_from_layout` path with
the verbatim tokenised header+rows. 2306 passed (+4), pyright net-zero.

domain/building_geometry.gross_heat_loss_wall_area(epc, identifier) sums
heat_loss_perimeter x room_height across a building part's storeys — the
heat-loss wall area (party walls excluded by construction), not total

reuse it; the calculator computes the same quantity inline today and
should be DRY'd onto this later (coordinated with the calculator branch).

recommend_cavity_wall(epc) detects an uninsulated main cavity wall
(wall_construction=4, wall_insulation_type=4) and emits a Recommendation
whose single Measure Option carries the Simulation Overlay setting MAIN
wall_insulation_type=2 (Table 6 'Filled cavity'; cf. domain/sap10_ml/
rdsap_uvalues.py u_wall). Returns None for already-insulated or
non-cavity main walls.
Recommendation/MeasureOption reshaped per design review: the target is
encoded in the Option's overlay (addresses a building part / window /
system), not a typed key on Recommendation — generalises to glazing and
heating without changing the type. CONTEXT partition wording generalised
to match.
Three behaviour tests (hand-built EPD, no PDF). Cost (behaviour 4 of
#1155) outstanding — needs net heat-loss wall area + ProductRepository.
