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.

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