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. emojiRegex exports a factory function returning a regular expression
  2. hasEmoji returns true when string contains standard emojis and false for plain text
  3. extractEmojis extracts all emoji occurrences from text
  4. extractEmojis correctly extracts complex emoji sequences including modifiers and zero-width joiners
  5. replaceEmojis replaces emojis in text with a replacement string or custom replacer function
  6. countEmojis returns the number of emojis found in text
  7. RGI_Emoji subpath exports a factory function returning regex for RGI emoji sequences
  8. text subpath exports a factory function returning regex for text presentation emojis
