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
- shouldInstrument is a callable function exported by @jest/transform
- shouldInstrument returns true for source files matching collectCoverageFrom patterns
- shouldInstrument returns false when collectCoverage option is disabled
- shouldInstrument returns false for ignored paths specified in coveragePathIgnorePatterns (e.g. node_modules)
- shouldInstrument returns false for test files matching testMatch or testRegex
- shouldInstrument returns true for test files when overridden by forceCoverageMatch
- shouldInstrument returns false for JSON files and files in __mocks__ directories
- handlePotentialSyntaxError is a callable function exported by @jest/transform
- handlePotentialSyntaxError returns non-SyntaxError instances unmodified without throwing
- handlePotentialSyntaxError throws enhanced SyntaxError containing code frame and Jest diagnostic explanation
