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. Calling loader.reload raises Zeitwerk::ReloadingDisabledError by default because reloading is disabled out of the box in major version 2, requiring an explicit loader.enable_reloading call before setup.
  2. assert loader.enable_reloading called after loader.setup raises Zeitwerk::Error with 'cannot enable reloading after setup'
  3. assert loader.reloading_enabled? returns false by default and true only after calling loader.enable_reloading before setup
  4. assert loader.reload with reloading enabled successfully unloads and reloads modified constants from disk
  5. assert failing to define the expected constant in a managed file raises Zeitwerk::NameError rather than standard NameError
