Scaffolding

Core Principles

1. Architecture-aware generation — Never scaffold without knowing the project's architecture (VSA, CA, DDD, Modular Monolith). If unknown, ask first or run the architecture-advisor questionnaire.
2. Complete vertical slices — Never generate half a feature. A scaffold includes endpoint, handler, validation, DTOs, EF configuration, and tests as a single unit.
3. Tests included by default — Every scaffolded feature includes at least one integration test using WebApplicationFactory + Testcontainers. Skip only if explicitly told to.
4. Modern C# 14 patterns — Primary constructors, collection expressions, file-scoped types, records for DTOs, sealed on all handler classes.
5. Convention-matching — Before generating, check existing code for naming patterns (*Handler, *Service, *Endpoint), folder structure, and access modifiers. Match what exists.

Scaffold Checklist (MANDATORY)

Every scaffolded feature MUST include ALL of the following. Do not skip any item:
