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. defaults.nyc exposes standard default configuration options including default exclude patterns, supported file extensions, and coverage settings
  2. defaults.testExclude provides default exclusion patterns and supported extensions (.js, .cjs, .mjs, .ts, .tsx, .jsx)
  3. defaults.instrumentVisitor provides default coverage variable names and global scope settings
  4. defaults.instrumenter combines visitor and parser generator defaults including babel parser plugins
  5. schema objects (nyc, testExclude, babelPluginIstanbul, instrumentVisitor, instrumenter) expose json-schema property definitions with types and descriptions
  6. defaults getters dynamically evaluate cwd property from process.cwd() and return isolated array instances
