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. rewritePattern and helper functions are exported as callable functions
  2. transformUnicodeProperties transforms unicode property escapes into character classes
  3. transformDotAll transforms dotAll flag s into pattern matching all characters including newlines
  4. transformNamedGroups transforms named capture groups and invokes onNamedGroup callback
  5. transformUnicodeSets transforms unicode sets v flag set operations into canonical character classes
  6. transformModifiers transforms inline modifier flags into standard regular expressions
  7. rewrite transforms regular expressions using custom transformation options
