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. gracefulify patches a standard file system module with retry queue capabilities
  2. readFile asynchronously reads file contents from disk with string and buffer encodings
  3. writeFile asynchronously creates and writes data to disk
  4. readFile returns ENOENT error when target file does not exist
  5. readFileSync synchronously reads file contents created by writeFileSync
  6. writeFile and readFile safely handle concurrent file system operations
