Schema-driven value generation helpers for testing.
Walks Zod schemas to generate valid values for route params, request bodies, and URL paths. Used by adversarial input, adversarial 404, and round-trip validation test suites.

(field_schema: ZodType<unknown, unknown, $ZodTypeInternals<unknown, unknown>>): string | null Detect format constraints on a field by converting to JSON Schema. Returns format string (e.g. 'uuid', 'email') or null.

(input_schema: ZodType<unknown, unknown, $ZodTypeInternals<unknown, unknown>>): Record<string, unknown> | undefined Generate a valid request body for a route's input schema.
Returns undefined for null schemas or schemas that can't be unwrapped to objects.
Throws if the generated body fails validation — catches broken generation logic
early with a descriptive error instead of a confusing 400 in downstream tests.

(field: ZodFieldInfo, field_schema: ZodType<unknown, unknown, $ZodTypeInternals<unknown, unknown>>): unknown Generate a valid-ish value for a field based on its base type.

(path: string, params_schema?: ZodObject<$ZodLooseShape, $strip> | undefined): string Resolve a route path with valid-ish param values so params validation passes. Used when testing input on routes that also have params.
