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. ansiRegex returns a RegExp instance for matching ANSI escape codes
  2. ansiRegex with default options returns a global regular expression
  3. ansiRegex with onlyFirst set to true returns a non-global regular expression
  4. ansiRegex matches standard text formatting and color escape sequences
  5. ansiRegex matches 256-color and 24-bit truecolor escape sequences
  6. stripAnsi removes all ANSI escape codes to return plain text
