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. timers contains original timer methods and constructors
  2. timers.setTimeout and clearTimeout remain native while global timers are mocked
  3. timers.setInterval and clearInterval remain native during clock installation
  4. timers.Date preserves native Date constructor when global Date is mocked
  5. timers.nextTick and timers.hrtime map to process timing functions in node
  6. withGlobal creates scoped timers object reflecting the custom global context
  7. runWithNativeTimeout executes using native timer even when fake timers are active
