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.strictEqual and assert.notStrictEqual validate primitive identity and differentiation
  2. assert.deepEqual and assert.notDeepEqual validate structural equality across nested objects and arrays
  3. assert.typeOf and assert.instanceOf verify value types and prototype inheritance
  4. assert.isAtLeast and assert.isAtMost validate inclusive numeric boundaries
  5. assert.include and assert.lengthOf verify collection contents and exact size
  6. assert.throws asserts function failure matching constructor or pattern and AssertionError is thrown on failed assertions
