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.

Contract
- browserslist.parseConfig(configString) parses multi-environment config text into section maps, stripping comments and empty lines
- browserslist.parseConfig('') on empty or comment-only string returns an object with an empty defaults array
- browserslist.findConfig(dir) discovers .browserslistrc files and returns structured section mappings
- browserslist.findConfig(dir) discovers package.json browserslist array configurations and wraps them under defaults
- browserslist.findConfig(dir) returns undefined when no configuration file exists in the directory tree
- browserslist.loadConfig({ path, env }) selects queries for the specified environment, defaulting to production
- browserslist.loadConfig({ path, env }) falls back to the defaults section when an unknown environment is requested
- browserslist(null, { path, env }) resolves target browsers directly from discovered configuration files
- browserslist.nodeVersions exposes an array of all known Node.js release versions used for node query resolution
