Contract

  1. z.object and primitive schemas validate structured data and parse conforming inputs with default values
  2. z.discriminatedUnion and schema transformations validate tagged variants and transform parsed payloads
  3. safeParse and ZodError formatting provide field-level error messages and structured error flattening
