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. AbortError is exported from es-toolkit root and es-toolkit/error subpath as the identical class constructor
  2. AbortError default instance inherits from DOMException and Error with message 'The operation was aborted'
  3. AbortError instance accepts a custom error message
  4. isAbortError correctly validates AbortError instances and rejects standard Error or non-error objects
  5. delay rejects with an instance of AbortError when an AbortSignal is aborted
