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
- assert dec_uint parses valid u8 within bounds and clears input stream
- assert dec_uint on 256 fails on overflow rather than silently truncating to 25 and leaving 6 in stream
- assert dec_int on -129 and 128 fails on underflow and overflow rather than truncating to -12 and 12
- assert take_escaped recognizes raw slice containing escape sequences without modifying or resolving escapes
- assert escaped transforms escape sequences into decoded owned String
- assert Stream peek_token and peek_slice inspect stream immutably without cloning or advancing input
- assert repeat with range 1..=3 greedily consumes up to upper bound without infinite looping
- assert separated stops before trailing delimiter leaving trailing separator unconsumed in stream
- assert Parser parse requires complete EOF stream consumption while parse_next mutates slice in-place
