POST /api/v1/parcels/{cad_num}/best-layouts — top layout patterns
(room_bucket × area_bin) у конкурентов в радиусе с ranking by velocity
из mv_layout_velocity + unit-mix recommendation для архитектурного ТЗ.
Service (backend/app/services/site_finder/best_layouts.py, 563 LOC):
- centroid lookup с fallback (cad_parcels → cad_quarters)
- competitors-in-radius через ST_DWithin
- aggregate по mv_layout_velocity per room_bucket
- supply batch query (один SQL вместо N) для sold_pct_of_supply
- Hamilton largest-remainder normalizer (sum_pct=100 invariant)
Endpoint (backend/app/api/v1/parcels.py, +24 LOC) после /competitors.
Tests (backend/tests/api/v1/test_parcel_best_layouts.py, 10 mock tests):
404, empty competitors, MV empty, exclude/filter, min_velocity, time_window
scaling, obj_class_filter, target_total_flats, 3-bucket ranking.
Phase 2.1 (без layout_type / balcony_count — отсутствуют в БД,
ждут B2B Объектив #52). Reuses PR A schemas/helpers, PR B MV.
NOTE: competitors.py:143 status='sold' carryover bug НЕ fixed —
отдельный follow-up issue. PR C использует MV (через
objective_corpus_room_month) что работает корректно.
