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 whitespace-separated tokens into trimmed values while preserving nested functions, parenthesized expressions, and quoted strings
  2. assert postcss.list.comma splits comma-separated CSS values while preserving nested commas within functional notation like rgb(), var(), and linear-gradient()
  3. assert postcss.list.comma preserves empty trailing tokens when ending with a trailing delimiter while postcss.list.space omits trailing whitespace tokens
  4. assert postcss.list.split splits a string by custom delimiter characters while ignoring delimiters inside quotes and parentheses
  5. assert postcss.list helper methods return an empty array when given an empty string or whitespace-only input
