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. A method annotated with `sig { returns(Integer).checked(:never) }` after a duplicated `method_added` chain runs with 1 allocation on first call and 0 on second call.
  2. The second invocation must stay allocation-free after first successful call, proving the wrapper is not dropped by a second `_on_method_added` event.
