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. Hfs creates an instance with a custom base implementation and confirms isBaseImpl
  2. Hfs write encodes string data and text decodes underlying bytes via the implementation
  3. Hfs logStart records method calls with arguments and logEnd retrieves the logged entries
  4. Hfs setImpl replaces active implementation and resetImpl restores the base implementation
  5. Hfs walk traverses directory structures depth-first and applies entry and directory filters
  6. Hfs rejects invalid path arguments and empty log names with TypeError
