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. createKeywordTypeNode constructs keyword type nodes for primitive TypeScript types (string, number, boolean, void, any, unknown, never)
  2. createKeywordType creates AST nodes for string names and SyntaxKind values using createKeywordTypeNode
  3. isKeywordType validates AST nodes as keyword type nodes and checks expected SyntaxKind
  4. getKeywordTypeName extracts human-readable keyword names and throws TypeError for non-keyword nodes
