Bytecode similarity to audited upstream with behavior deviation

Circle USYC's assessment for RD-F-171 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

No public USYC GitHub repo to diff bytecode against any upstream. USYC is an original implementation with no declared upstream, so bytecode-similarity-to-audited-upstream AI-copy risk check is not performable.

Methodology #

Determine whether the bytecode has high structural similarity to an audited upstream but deviates in state-mutation ordering (AI-generated copy risk pattern).
