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 generates 21-character URL-safe identifiers by default
- assert nanoid respects custom length parameter and returns empty string for size 0
- assert nanoid throws RangeError with 'Wrong ID size' on negative sizes
- assert customAlphabet produces identifiers restricted to the specified character set
- assert customAlphabet generator respects default size and runtime size overrides
- assert urlAlphabet contains 64 URL-safe characters
- assert sequentially generated identifiers are unique
