Jun-te Kim 2851a0151b Drop phantom alternative-wall building parts lodged inline (reinstates dropped fix) ... Task b9fcd354-2a33-4fc4-a64e-388c060a055c (portfolio 824 / scenario 1278) still failed 5 of 128 batches with NotNullViolation on epc_building_part.construction_age_band even after the SAP-Schema-15.0 mapper landed (PR #1531). Cert 8169-6926-5310-0447-8996 (UPRN 100010344955, SAP-Schema-15.0) lodges a bare alternative-wall record (wall_area/wall_construction/wall_insulation_type, no identifier, age band, or floor dimensions) as a second sap_building_parts element rather than under a distinct sap_alternative_wall_1 key. RdSapSchema17_1 (which the 15.0/16.x reduced-field mappers delegate to) has no alt-wall slot to route it to, so it persisted as a phantom building part with a null age band. _drop_building_parts_without_age_band already solved exactly this shape of problem for lodging artifacts (ae81a81e), but that commit sits on fix/drop-building-part-without-age-band, an unmerged branch that has since drifted far behind main. Reinstating the same filter (fresh, not cherry-picked) fixes both the original artifact case and this SAP-15 alt-wall case, since RdSapSchema17_1 has nowhere else to put it either way. Verified against all 174 properties across the task's originally-failing batches: zero remaining null-age-band building parts.
