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.clean strips surrounding whitespace, equal signs, and v prefixes from a valid semantic version string
  2. semver.clean retains prerelease identifiers but omits build metadata from the returned cleaned version
  3. semver.clean returns null for invalid versions, range operators, wildcard versions, and non-empty strings with separated prefixes
  4. semver.clean throws TypeError when passed non-string arguments
  5. semver.clean accepts an optional loose boolean flag or options object
  6. isCleanable helper safely returns boolean without throwing on invalid or non-string inputs
