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
- customRandom generates deterministic identifiers from custom byte generator functions and supports runtime size overrides
- assert customRandom with a seeded generator function produces exact repeatable IDs
- assert customRandom generator respects default size and explicit size overrides
- assert customRandom discards bytes above safe cutoff to prevent modulo bias on non-power-of-two alphabets
- assert random returns Uint8Array buffer of requested byte length and throws RangeError on negative size
- assert urlAlphabet contains 64 unique URL-safe characters
