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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""Behaviour of the floor Recommendation Generator: detecting an uninsulated

ground floor and its construction (suspended vs solid), emitting the matching

single insulation Option with overlay + priced Cost. A floor is one

construction, so this is a single-Option Recommendation (like cavity walls).
