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.

Contract
- @types/deep-eql package.json declares type definitions entry point index.d.ts and version 4.0.2
- @types/deep-eql index.d.ts exports deepEqual function declaration accepting leftHandOperand, rightHandOperand, and optional options
- @types/deep-eql index.d.ts declares deepEqual.MemoizeMap class extending WeakMap
