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. TimeoutError and AbortError instances have name set to 'Error' rather than 'TimeoutError' or 'AbortError' because their constructor calls super(message) without passing the error name to DOMException
  2. withTimeout rejects on timeout with a TimeoutError whose name is 'Error' and code is 0
  3. delay rejects on aborted signal with an AbortError whose name is 'Error' and code is 0
  4. catching TimeoutError or AbortError requires instanceof or constructor.name checks rather than name property equality
  5. compat isError returns false for TimeoutError and AbortError because DOMException uses the [object DOMException] tag
