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. isExtglob returns true for extended glob patterns containing @, !, ?, *, and + prefix operators
  2. isExtglob returns false for regular file paths and non-extglob standard glob patterns
  3. isExtglob returns false for escaped extglob patterns where the operator is preceded by a backslash
  4. isExtglob returns false when provided non-string values or empty strings
  5. filterExtglobs filters an array of pattern strings and returns only those matching extglob syntax
