recommend_heating now receives planning_restrictions in the orchestrator (the ASHP planning gate); the ASHP bundle joins the free candidate pool for every house/bungalow. Catalogue + contingency (legacy 0.25) gain air_source_heat_pump; report.py _triggers_for explains the ASHP trigger; the harness forcing test covers it. Integration tests seed an air_source_heat_pump MaterialRow (ASHP fires on every house, the broadest trigger yet). NB the optimiser correctly does NOT select ASHP for an EPC-band goal — gas->electric does not improve the SAP cost-rating; ASHP is a CO2/PE measure, selectable once non-EPC goals land. ASHP bundle COMPLETE (S5-S7). ADR-0024. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
