Объединяет наше (площади из реальной геометрии teap) + полноту девелоперской Excel-модели (каскад затрат + БДР с налогами). Расширяет financial.py из статического GDV−COST в полный статический расчёт. БЕЗ DCF (PR-3), БЕЗ новых вводных от пользователя — только нормативы + существующий TEAP. Каскад (financial.py): - Выручка: жильё (residential×price) + ПАРКИНГ (spaces×1.9М) - Затраты: СМР(резид+паркинг) + ПИР 2.5% + сети/ТУ 6000₽/м² + услуги заказчика 1.5% + резерв 3% + маркетинг/риэлтор 7% выручки + земля - БДР: валовая маржа → НДС (упрощённо) → прибыль до налога → налог 25% (ФЗ 176-ФЗ) → ЧИСТАЯ прибыль → ROI + чистая маржа% - Нормативы документированы (источник: Excel-эталон «Авангардная 13» + RU-рынок) FinancialModel (concept.py): +16 additive-полей (revenue breakdown, cost cascade, БДР/налоги, roi, margin_pct, irr_is_proxy). Старые 4 поля сохранены (backward-compat). IRR честно помечен irr_is_proxy=True (annualized net ROI, не DCF) — настоящий IRR/NPV/PBP в PR-3 (помесячный cashflow). НДС — документированное упрощение, не точный НК РФ. Офисы пропущены (нет площади в TEAP). PDF + concept UI: полный БДР-каскад + чистая прибыль/ROI + честные сноски. api-types.ts регенерён авторитетно (openapi-typescript + prettier, как CI). mypy strict clean (generative.*), +тесты (каскад/паркинг/налоги/backward-compat/ edge cost=0), 36 passed.
