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. difflib.SplitLines splits multi-line string into lines using strings.SplitAfter and ensures trailing newline on final element
  2. difflib.SplitLines produces trailing empty line entry when input ends with newline
  3. difflib.SplitLines returns single newline slice when given empty string input
  4. difflib.SplitLines preserves carriage return character in Windows CRLF line endings
