recommend_heating joins the free candidate pool in _candidate_recommendations; the HHR storage bundle reaches the optimised package for an electric/off-gas dwelling. Catalogue + contingency (legacy 0.10) gain high_heat_retention_storage_heaters; report.py _triggers_for explains the heating trigger (electric/off-gas main); the harness _GENERATOR_MEASURE_TYPES forcing test covers it. ASHP + boiler bundles still to come. ADR-0024. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
