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. computeLineStarts calculates 0-indexed line start offsets for multiline source code
  2. computeLineStarts handles various newline delimiters including CRLF and LF
  3. getPositionLineAndCharacter maps character offsets to line and character positions
  4. extractLineText retrieves the exact line content for a given line index
