SudoSOS Back-end API / internal/middleware / AsyncValidatorMiddleware

Class: AsyncValidatorMiddleware

Middleware that runs async (potentially DB-hitting) validation specs against the request body before passing to the handler. Runs after RequestValidatorMiddleware (structural Swagger check) and returns the same { valid, errors[] } shape on failure, ensuring a consistent 400 response regardless of which layer caught the error.

If no spec is registered in the registry for the given model name, the middleware is a no-op and calls next() immediately.
