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 `Zeitwerk::Loader#on_load` accepts a leading double-colon constant path and does not raise at registration (`::User`)
  2. assert eager loading registers and triggers the callback for `::User` by observing the callback firing when the constant is loaded
  3. assert malformed constant paths still fail by raising `NameError` for `:User`
