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. default exports a function that formats code frames pointing to a line and column location
  2. default highlights a single line-column location with gutter line numbers, active line indicator, and caret marker
  3. default highlights an entire line when column number is zero or omitted
  4. default attaches a custom error message next to the highlighted caret marker
  5. default restricts surrounding visible context using linesAbove and linesBelow options
  6. default offsets displayed line numbers using startLine option
