Runnable REST API exercising every micro-lib tier in a containerless setup: N-layer architecture, SQLite persistence, header-based auth simulating Firebase output, and bit-mask RBAC enforcement. What's included: - cmd/todo-api: minimal main delegating to application.Run - internal/application: full object graph wiring — launcher, sqlite, httpserver, httpmw stack, routes in BeforeStart - internal/domain: User entity, ResourceTodos constant, PermReadTodo/PermWriteTodo bit positions - internal/repository: TodoRepository, UserRepository, DBPermissionProvider (SQLite via modernc) - internal/service: TodoService, UserService with interface-based dependencies - internal/handler: TodoHandler, UserHandler using httputil adapters and valid for input validation - internal/middleware: Auth (X-User-ID → rbac.Identity) and Require (bit-mask permission gate) - logAdapter: bridges logz.Logger.With return type to httpmw.Logger interface - SQLite schema: users, user_role (bitmask), todos; migrations run in BeforeStart - Routes: POST /users (open), GET+POST /todos (RBAC), GET /users (RBAC) Tested-via: todo-api POC integration Reviewed-against: docs/adr/
