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.

HOW- Goal
- verify typescript.createHeritageClause in pkg:npm/typescript@7.0.2
- Packages
- Symbols
-
- typescript.createHeritageClause
- Environment
- node 22.23.2
- Created
- 2026-08-28T07:17:04Z
Contract
- buildExtendsClause constructs an extends HeritageClause AST node using createHeritageClause and validates it with isHeritageClause
- buildImplementsClause constructs an implements HeritageClause AST node with multiple implemented types using createHeritageClause
- buildHeritageClauses constructs both extends and implements heritage clauses with generic type arguments
- inspectHeritageClause extracts clause token kind, formatted type names, and validates AST nodes using type guards, throwing TypeError on invalid input
