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 Text.from_ansi('hello\n').plain == 'hello\n' preserving trailing newlines
  2. assert Text.from_ansi('\n').plain == '\n' without stripping bare newline
  3. assert Text.from_ansi('\x1b[32mSUCCESS\x1b[0m\n').plain == 'SUCCESS\n' with styled span
  4. assert Console.print(end='') with empty objects outputs '' instead of hardcoded '\n'
  5. assert Console.print(end='\r') outputs '\r'
  6. assert empty NO_COLOR='' env var does not disable console colors
