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. blackfriday.Document is the root NodeType returned by Parser.Parse representing the markdown document AST
  2. blackfriday.Document root node holds child block elements with parent pointer referencing the Document node
  3. blackfriday.NewNode with Document type creates an empty Document AST node
  4. Node.Walk traverses the AST starting with entering blackfriday.Document and ending with exiting Document
  5. blackfriday.New.Parse on empty markdown returns a Document root node with nil child pointers
