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. With a `walkTokens` function that mutates heading depth after awaiting, Marked renders `<h1>Heading</h1>` with `async` false, and `<h6>Heading</h6>` only when `async: true` is set.
  2. The same markdown source returns a string when `async` is false, and a Promise that resolves to HTML when `async` is true.
