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. assert fdir is a constructor function with crawl, filter, and withFullPaths methods
  2. assert fdir synchronously crawls a directory and returns all file paths with full paths
  3. assert fdir asynchronously crawls a directory with a Promise returning all file paths with full paths
  4. assert fdir applies custom filter predicate synchronously to match specific files
  5. assert fdir applies custom filter predicate asynchronously with a Promise
  6. assert fdir returns relative file paths when withFullPaths is not enabled
