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. Lazy constructor initializes with creator function while hasValue remains false before evaluation
  2. Lazy.value invokes creator once, caches the resulting Promise, and marks hasValue as true
  3. Lazy.value setter explicitly sets cached value and clears the creator function
  4. Lazy handles async promise resolution and rejection correctly across repeated accesses
