- FastAPI backend: PostGIS estimator + 3 scrapers (Avito/Cian/Yandex)
- Next.js 15 frontend: tradein.html mockup design, basePath=/trade-in
- WeasyPrint PDF (Брусника-style 4-page report)
- Address autocomplete с typo-tolerance + 6 EKB presets
- Изолированный docker stack gendesign-tradein (отдельная postgres БД)
- Caddy inline routes: gendsgn.ru/trade-in/* и /trade-in/api/v1/*
- Forgejo Actions: .forgejo/workflows/deploy-tradein.yml (shell-based GHCR login)
- Триггер только по paths: tradein-mvp/** (не пересекается с deploy.yml)
- Образы: ghcr.io/lekss361/gendesign-tradein-{backend,frontend}:latest
Первый запуск на сервере (вручную, один раз):
- создать /opt/gendesign/tradein-mvp/.env.runtime (postgres pwd, contact email)
- docker network create gendesign_shared (если нет)
- docker compose -p gendesign-tradein up -d
- docker compose -p gendesign exec caddy caddy reload
