Package: restrictR 0.2.0

restrictR: Composable Runtime Contracts

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 domain-specific language, no operator overloading, just idiomatic R.
