ADR-0019 warns that wall_construction code 8 is Park home (PH), NOT system-
built. It was already excluded (8 isn't in the constructable-options map), but
only implicitly. Add an explicit early-return + named constant so a park home
can never be mis-keyed as system-built, with a pin as the tripwire. A park
home's proprietary panel is never EWI/IWI-suitable.

domain/modelling/ had grown to 15 flat modules. Group the behavioural ones into
subpackages — generators/ (wall/roof/floor Recommendation Generators), scoring/
(overlay applicator, package scorer, role-1/3 scoring), optimisation/ (optimiser
+ measure dependency) — and leave the shared value-object vocabulary
(recommendation, plan, scenario, product, contingencies, simulation) flat at the
top, since it is imported everywhere. Pure move + import-path rewrite across 89
import sites; no behaviour change. 136 pass, pyright strict clean.

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).
pyright strict clean.

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.
WIP on #1155. pyright strict clean.
