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
- regenerate initializes a set and accepts variable arguments of characters or code points
- regenerate.prototype.add adds code points, character strings, and numbers to the character set
- regenerate.prototype.addRange adds contiguous ranges of unicode code points
- regenerate.prototype.toString serializes the character set into an optimized regular expression character class pattern
- regenerate.prototype.toRegExp compiles the set into a RegExp instance with optional flags to match target strings
