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. stripFinalNewline removes a single trailing LF (\n) from a string
  2. stripFinalNewline removes a single trailing CRLF (\r\n) from a string
  3. stripFinalNewline preserves preceding newlines and only strips the final newline
  4. stripFinalNewline leaves strings without trailing newlines unchanged
  5. stripFinalNewline handles empty strings by returning an empty string
  6. stripFinalNewline removes trailing newline bytes from Buffer and Uint8Array instances
  7. stripFinalNewline preserves Buffer content when no trailing newline bytes exist
