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 postcss.list.space splits CSS values by whitespace while preserving function arguments and quoted strings
  2. assert postcss.list.comma splits comma-separated lists while preserving nested commas inside functions and quotes
  3. assert postcss.list.split splits strings by custom separator characters while respecting parenthesis nesting and quotes
  4. assert postcss.list handles escaped characters, tabs, newlines, and nested parentheses without incorrect splitting
  5. assert postcss.list methods return an empty array when given empty or falsy input strings
