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. TestExclude.prototype.shouldInstrument returns true for files matching explicit include patterns
  2. TestExclude.prototype.shouldInstrument returns false for files matching explicit exclude patterns
  3. TestExclude.prototype.shouldInstrument excludes default test and config patterns when exclude is not customized
  4. TestExclude.prototype.shouldInstrument excludes node_modules by default
  5. TestExclude.prototype.shouldInstrument returns false for files outside configured working directory
  6. TestExclude.prototype.shouldInstrument returns false for file extensions outside configured extension list
  7. TestExclude.prototype.shouldInstrument supports negation patterns in exclude rules
