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 freeze_time decorator works on callables taking a keyword argument named 'func' without raising TypeError from internal wrapper signature collisions
  2. assert freeze_time decorator works on callables taking a keyword argument named 'time_factory' when as_kwarg is not targeting that parameter
  3. assert freeze_time decorator on generator functions keeps datetime frozen throughout iteration and also supports 'func' parameter
  4. assert freeze_time with as_kwarg coexists with user parameters named 'func' without collision
  5. assert freezegun version is 1.5.5 or later where _call_with_time_factory isolates kwargs dict
