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. Bun.deepEquals returns false when comparing a numeric-keyed plain object to a Uint8Array with matching elements and length, verifying internal typed-array slots rather than only enumerable index properties
  2. Bun.deepEquals returns false when comparing a Date instance to an empty object sharing Date.prototype
  3. Bun.deepEquals returns true when comparing two Uint8Array instances containing identical byte sequences
  4. expect().toEqual in bun:test throws an assertion error when comparing a numeric-keyed plain object against a TypedArray
