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

Contract

  1. mimetype.Detect returns MIME type and extension from byte slice
  2. mimetype.DetectReader returns MIME type and extension from io.Reader
  3. mimetype.MIME.Is matches MIME type ignoring optional parameters
  4. mimetype.MIME.Parent returns parent MIME in hierarchy
  5. mimetype.EqualsAny returns true when string matches any candidate
