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
- nanoid/non-secure functions return an empty string for negative or non-positive sizes rather than throwing RangeError like root nanoid
- assert nanoid() from nanoid/non-secure generates 21-character URL-safe identifiers by default
- assert nanoid/non-secure customAlphabet produces IDs restricted to the custom alphabet at requested lengths
- assert negative sizes passed to nanoid/non-secure return empty strings while root nanoid throws RangeError
- assert float sizes are truncated to integer via bitwise OR and non-numeric sizes evaluate to empty strings
