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
- package.json defines types entry point index.d.ts and conditional exports mapping default and import types
- The referenced index.d.ts declaration file exists and defines core TypeScript function declarations load, loadAll, and dump
- index.d.ts defines option interfaces LoadOptions, DumpOptions, TypeConstructorOptions, and SchemaDefinition
- index.d.ts defines classes Type, Schema, and YAMLException with Mark and State interfaces
- index.d.ts defines built-in schema constants FAILSAFE_SCHEMA, JSON_SCHEMA, CORE_SCHEMA, and DEFAULT_SCHEMA
- index.d.mts exists and provides ESM wildcard and default type re-exports from index.js
