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.Heading identifies heading AST nodes parsed from ATX and setext Markdown headers.
  2. blackfriday.Heading nodes carry HeadingData with Level corresponding to the header depth (1-6).
  3. blackfriday.Heading nodes can be traversed with Node.Walk with entering true and false states.
  4. blackfriday.Heading nodes populate HeadingID in HeadingData when AutoHeadingIDs or HeadingIDs extensions are enabled.
  5. blackfriday.NewNode with blackfriday.Heading creates an AST node of Type Heading with configurable HeadingData.
