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