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. semver.neq returns true when two version strings represent different semantic versions
  2. semver.neq returns false when two version strings are semantically identical including with prefixes or whitespace
  3. semver.neq distinguishes between differing prerelease identifiers and release versions
  4. semver.neq treats versions differing only by build metadata as semantically equal returning false
