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
- Converting Headers to a standard dictionary collapses duplicate header keys into a single comma-delimited string rather than preserving discrete wire occurrences or lists.
- Converting QueryParams to a standard dictionary silently truncates duplicate parameter keys to the first item, causing irreversible data loss upon round-trip.
- QueryParams mutation methods (add, set, remove) return new immutable instances leaving the original QueryParams instance unmodified.
- Request form data serializes multi-value lists as repeated application/x-www-form-urlencoded key-value pairs with boolean and integer values stringified.
- Accessing content on an unbuffered streaming or multipart Request raises RequestNotRead until read() is explicitly invoked.
