"""Forecasting services — детерминированный форсайт-слой Site Finder v2.

#951 (Site Finder v2 / «GG-форсайт», EPIC 7 «Чувствительность к ключевой ставке»).

Этот пакет — фундамент data-independent логики прогноза: monthly макро-ряды,
классификатор режима ставки, лаговые помощники. Всё ДЕТЕРМИНИРОВАННО, БЕЗ LLM.

Слои (по PR):
  • macro_series  (#951b)          — monthly макро-ряд + классификатор режима ставки (X-ось §9.6).
  • sales_series  (#951c)          — monthly ряд продаж по сегменту (Y-ось §9.6).
  • rate_sensitivity (#951d)       — §9.6 чувствительность продаж к key_rate (CORE, ADVISORY).
  • macro_coefficient (#951e)      — §9.5 макро-коэффициент (композитный множитель, ADVISORY).
  • demand_normalization (#951f)   — §9.4 нормализация спроса под смену режима ставки (ADVISORY).
  • demand_supply_forecast (#952a) — §9.8 центральный движок: спрос (§9.4ק9.5) vs
    предложение (§9.3) по горизонтам → баланс/индекс дефицита (СБОРКА, ADVISORY).
  • what_to_build (#981/952-B)     — §9.7 ранкер сетки сегментов по deficit_index
    (прогон #980 per-cell → DESC «что строить»; СБОРКА, ADVISORY).
  • affordability (#981/952-B)     — §7.9 MAI: ДЕГРАДИРОВАННЫЙ прокси платёжной
    нагрузки (субсид. ставка, дохода нет → low-confidence; СБОРКА, ADVISORY).
  • scenarios (#984/954-A)         — §11 три макро-сценария (conservative/base/
    aggressive) прогоном #952 под тремя конвертами ставки (СБОРКА, ADVISORY).
  • product_scoring (#985/954-B)   — §14.2 десять продуктовых скоров ∈ [0,1] (выше=
    лучше) + взвешенный overall (renorm над доступными) + §16 причина на скор;
    сводит #950…#984 + live-стек, graceful-None, ADVISORY.
  • special_indices (#986/954-C)   — §25 шесть специальных индексов (Launch Window,
    Product Void, Cannibalization, Competitor Strength, Artificial Demand, Cost-of-
    Error); сборка над #980/#981/§9.1/§9.2/§7.9, per-index graceful-None, ADVISORY.

Источники данных:
  • макро — таблица macro_indicator через reader site_finder/macro.py (reuse).
  • продажи — objective_corpus_room_month / objective_lots (см. sales_series).
