Add backend/app/services/forecasting/sales_series.py — deterministic monthly sold-units (+area+avg price) time series per SegmentSpec, the Y-axis foundation for the §9.6 key-rate regression. Two sources with distinct authority: objective_corpus_room_month (class/district aggregates, full ДДУ+ДКП, count- weighted price ×1000 тыс→₽) and objective_lots (room×area×price segmentation, GROUP BY date_trunc registration_date; survivorship caveat documented). Pure DB-free helpers price_bucket_of / room_area_bucket_of / log_diff / fill_month_grid, unit-tested. In-SQL CASE bucketing shares the same threshold constants as the helpers (bound params) → no Python↔SQL drift. Months with no sales → units=0 (real zero), area/price → None. Graceful empty/thin → low confidence, zero-filled grid. Mirrors macro_series.py (PR2). room_bucket semantics are source-specific (documented on SegmentSpec). 62 tests, ruff clean. |
