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. charset_normalizer.from_bytes(data) detects encoding from raw byte sequences
  2. matches.best() returns the highest-scoring CharsetMatch object
  3. best.encoding provides the normalized encoding identifier
  4. str(best) provides the decoded unicode string
  5. best.byte_order_mark identifies the presence of UTF-8 BOM
  6. from_bytes raises TypeError when input is not bytes or bytearray
