Composable Runtime Contracts for R R package restrictR version 0.1.0 Build reusable validators from small building blocks using the base pipe operator. Define runtime contracts once with 'restrict()' and enforce them anywhere in code. Validators compose naturally, support dependent rules via formulas, and produce clear, path-aware error messages. No DSL, no operator overloading, just idiomatic R.
