enforcing-principles

Use when implementing features, handling errors, adding validation, creating forms, writing database migrations. Enforces fail-fast (NO retry logic, circuit breakers), single entry point (unified data provider, Zod at API boundary), form defaults from schema (zodSchema.partial().parse), TypeScript (interface vs type), React Admin patterns. NEW (2024-12): Zod security (z.strictObject, string .max() limits, z.coerce for forms, z.enum allowlist), form performance (onSubmit/onBlur mode, useWatch not watch). BLOCKS anti-patterns, SUGGESTS best practices.
