Implementazione completa del backend FastAPI: - Modelli SQLAlchemy: User, Recipe, RecipeVersion, RecipeTask, RecipeSubtask, Measurement, AccessLog, SystemSetting, RecipeVersionAudit - Schemas Pydantic v2 per tutti i CRUD + statistiche SPC - Middleware: API Key auth (X-API-Key) con role checking + access logging - Router: auth, users, recipes, tasks, measurements, files, settings - Services: auth (bcrypt+secrets), recipe (copy-on-write versioning), measurement (auto pass/fail con UTL/UWL/LWL/LTL) - Alembic env.py con import modelli attivi - Fix architect review: no double-commit, recipe_id subquery filter, user_id in access logs, type annotations corrette Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
