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. status(code) returns the canonical HTTP status message string (e.g. status(200) === 'OK')
  2. status(message) returns the HTTP status code for valid message strings case-insensitively (e.g. status('not found') === 404)
  3. status.message[code] maps numerical status codes to status message strings
  4. status.code[message] maps lowercase status message strings to numerical status codes
  5. status.codes lists all supported numeric HTTP status codes
  6. status.empty[code] identifies status codes with empty response bodies (e.g. 204, 304)
  7. status.redirect[code] identifies redirect status codes (e.g. 301, 302)
  8. status.retry[code] identifies retryable status codes (e.g. 503)
  9. status(invalid) throws an error for unknown status codes or messages
