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. which.sync resolves the path to an executable from a custom search path
  2. which.sync throws an ENOENT error when the executable is not found
  3. which.sync with nothrow option returns null when the executable is not found
  4. which.sync with all option returns an array of all matching executable paths
  5. which.sync respects custom path delimiter with colon option
  6. which.sync directly resolves executable paths containing directory slashes
  7. findExecutableSync and tryFindExecutableSync helper functions correctly wrap which.sync behavior
