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 a loader without `enable_reloading` raises `Zeitwerk::ReloadingDisabledError` on `reload` after `setup`, and then `unload` keeps a previously loaded constant in place
  2. assert enabling reloading after `setup` raises `Zeitwerk::Error` and leaves `reloading_enabled?` false
  3. assert enabling reloading before `setup` makes `unload` remove a loaded constant so that the next reference is a `NameError`
