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. assert encoding existence checks return true for supported legacy encodings and false for unknown encodings
  2. assert Korean EUC-KR encoding and decoding roundtrip preserves original text and produces valid byte buffer
  3. assert Japanese Shift_JIS encoding and decoding roundtrip preserves original multibyte text
  4. assert Cyrillic Windows-1251 encoding and decoding roundtrip preserves original text accurately
  5. assert UTF-8 encoding with addBOM prepends byte order mark 0xEF 0xBB 0xBF and default decoding strips BOM while explicit option retains BOM
  6. assert stateful chunked decoder correctly decodes multibyte character stream split across chunk boundaries
