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. addHook transforms source code during CommonJS require execution
  2. revert function restores original module loader and removes transformation
  3. exts option allows adding require hooks for custom file extensions
  4. matcher function selectively determines whether a file should be transformed
  5. createReplacerHook utility correctly transforms targeted code and reverts
  6. hook returning a non-string value throws an Error
  7. passing a non-string extension throws a TypeError
