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. browserslist.parseConfig parses INI-like configuration strings with comments and section headers into environment query maps
  2. browserslist.findConfigFile locates .browserslistrc or package.json containing browserslist configuration in directory hierarchy
  3. browserslist.findConfig extracts environment query mappings from discovered configuration files
  4. browserslist.loadConfig resolves targeted queries for specified environment names such as production or development
  5. browserslist resolves browser target lists based on discovered configuration files when queries argument is undefined
  6. browserslist.findConfigFile and loadConfig return undefined when no configuration file exists in directory hierarchy
