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_floor_insulation(epc, products) detects an uninsulated ground floor
(SapBuildingPart.floor_insulation_thickness blank/zero) and its construction
from floor_construction_type — 'Suspended timber' -> suspended_floor_insulation,
'Solid' -> solid_floor_insulation — emitting the matching single Option (a
floor is one construction, like a cavity wall) with the overlay
(floor_insulation_thickness = 100 mm) and a priced Cost (ground-floor area x
the Product's fully-loaded unit cost + contingency).
- building_geometry.ground_floor_area(epc, identifier): the lowest floor's
(floor == 0) area. Pinned 14.85 m^2 on 000490 MAIN.
- BuildingPartOverlay gains floor_insulation_thickness (generic Applicator
writes it unchanged). suspended (0.20) / solid (0.26) floor contingencies.
Progress on #1159 (generator + geometry); end-to-end + Elmhurst pin pending
the orchestrator (#1157) and parser. Four behaviour tests (suspended / solid
/ none / cost) + geometry pin. pyright strict clean.
