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.

Contract
- from_fp() accepts a binary stream (io.BytesIO) and returns a CharsetMatches collection containing CharsetMatch results.
- best() on CharsetMatches returns the highest-scoring CharsetMatch whose .encoding, .raw, and string conversion yield the decoded text.
- from_fp() correctly identifies distinct encodings such as UTF-8, UTF-16-LE with BOM, and UTF-8 with BOM from binary streams.
- from_fp() accepts customization parameters including steps, chunk_size, and threshold for tuning charset detection.
- from_fp() raises TypeError, AttributeError, or ValueError when passed an incompatible text stream instead of a binary file pointer.
