This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. zod.ZodType is the base schema constructor and primitive and composite schemas are instances of ZodType
  2. ZodType parse method synchronously validates valid input and throws ZodError on invalid input
  3. ZodType safeParse method returns success result object with parsed data or failure object with error issues
  4. ZodType optional, nullable, and default combinator methods produce schema instances handling undefined and null values
  5. ZodType refine and transform methods create validation pipeline stages for custom assertions and data transformation
  6. ZodType pipe and or combinators compose sequential schema validation and type unions
