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. isCI exports a boolean indicating whether execution is within a continuous integration environment
  2. name exports a string or null indicating the detected continuous integration vendor name
  3. isPR exports a boolean or null indicating if a pull request is being tested
  4. vendor constants export boolean flags for specific CI providers including GITHUB_ACTIONS, TRAVIS, CIRCLE, and GITLAB
  5. _vendors exports an array of supported vendor constant identifiers
  6. evaluates environment variables dynamically on load to detect CI presence and vendor name
