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
- Reader::fromString with default escape '\\' treats trailing backslashes before quotes as escape sequences, merging multiple CSV columns into a single mangled field
- Reader::setEscape('') disables the non-standard PHP escape character to enforce RFC 4180 compliance and split columns accurately
- Reader::setHeaderOffset(0) with setEscape('') correctly populates associative column headers instead of assigning null to subsequent columns
- Writer::setEscape('') emits valid RFC 4180 fields and guarantees clean roundtrip parsing with Reader::setEscape('')
