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. assert new postcss.Warning constructs warning object with type 'warning', custom text, and copies optional metadata
  2. assert Warning automatically derives line, column, endLine, and endColumn coordinates from AST node source ranges
  3. assert Warning calculates line and column offsets when word or index options are specified for an AST node
  4. assert warning.toString formats messages based on presence of AST node, plugin name, and source location
  5. assert result.warn instantiates Warning with active plugin context and appends it to result messages and warnings
