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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

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