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
- deepEql returns true for identical primitives and false for distinct primitives
- deepEql treats NaN as equal to NaN and distinguishes +0 from -0
- deepEql evaluates Date instances by their timestamps
- deepEql evaluates RegExp instances by their source pattern and flags
- deepEql evaluates Error instances by name, message, and custom properties
- deepEql evaluates nested arrays, sets, and maps recursively
- deepEql evaluates nested objects regardless of key order and includes symbol properties
- deepEql handles circular references without throwing stack overflow errors
- deepEql supports custom comparator functions to override equality logic
- deepEql supports custom memoize maps via MemoizeMap
