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. assert customRandom returns a generator function configured with alphabet and default size
  2. assert customRandom generator produces identifiers of specified default length containing only valid alphabet characters
  3. assert customRandom generator supports dynamic size override at invocation time
  4. assert customRandom generator returns an empty string when requested size is zero or negative
  5. assert customRandom produces repeatable deterministic identifiers when supplied with a seeded pseudo-random generator
  6. assert customRandom operates correctly with nanoid default hardware random generator and custom hex alphabet
  7. assert customRandom handles non-power-of-two alphabets without modulo bias
