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
- getLineInfo resolves accurate 1-indexed line and 0-indexed column positions for character offsets
- tokTypes exposes standard token definitions to classify numeric, string, and identifier tokens
- Parser.extend creates a subclassed parser that modifies AST construction through custom plugins
- Parser.extend supports chaining multiple plugins together to enrich parser functionality
- extended parser preserves standard ECMA options while executing plugin hooks
