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.

Contract
- z.object and primitive schemas (z.string, z.number, z.boolean) validate structured data and parse conforming inputs
- safeParse returns success true with parsed data on valid payloads and success false with structured error issues on failure
- z.coerce converts string and number representations to target primitives including numbers, booleans, and dates
- z.discriminatedUnion and z.union validate tagged variants and multi-type inputs against matching schema members
- schema modifiers including optional, nullable, and default handle absent keys, null values, and default fallbacks
- schema refine and transform apply custom predicate validations and data transformations
