Use `satisfies` to validate without widening | BeforeMerge Rules | BeforeMerge

Why this matters

satisfies checks that a value conforms to a type without widening it, so you keep precise key and literal types for downstream inference.

// Bad — widens, loses key/literal precision
const config: Record<string, string> = { env: "prod" };
config.env; // string, and config.foo is allowed
 
// Good — validated but precise
const config = { env: "prod" } satisfies Record<string, string>;
config.env; // "prod"
