Signed/unsigned arithmetic confusion
Jito's assessment for RD-F-018 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Rust's type system enforces signed/unsigned separation at compile time. Implicit i64/u64 casts generate Clippy warnings. Certora FV covers arithmetic invariants. No signed/unsigned confusion finding in any published audit.
