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. Tags before dive validate map collection entry count, tags between keys and endkeys validate each map key, and tags after endkeys validate each map value.
  2. Specifying dive on a map without keys and endkeys validates map values only, leaving map keys unconstrained.
  3. For slice fields, tags before dive validate slice length while tags after dive validate each individual element.
