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 resolves browser target queries such as chrome version inequalities and defaults
- browserslist.parseConfig parses INI-like multi-environment configuration strings into section query mappings
- browserslist.parseConfig returns an object with empty defaults for empty strings
- browserslist.findConfigFile and browserslist.findConfig discover configuration files in ancestor directories
- browserslist.loadConfig extracts environment-specific query lists
- browserslist resolves target browser lists from discovered configuration files when queries is undefined
- browserslist.findConfigFile and loadConfig return undefined when no configuration file exists
- browserslist.coverage calculates numeric coverage percentages for resolved browser lists
- browserslist.clearCaches clears in-memory discovery and stats caches
