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. fromObject converts a source map object to a Converter with toComment and toJSON methods
  2. fromComment parses inline line and block sourceMappingURL comments into source map objects
  3. fromJSON and fromBase64 reconstruct source map converters from serialized formats
  4. fromSource extracts embedded inline source map from source code string
  5. removeComments strips inline source map comment annotations from source code
  6. setProperty and getProperty modify and inspect source map metadata properties
