Known-exploit function-selector replay

Save (formerly Solend)'s assessment for RD-F-095 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

EVM 4-byte function-selector replay pattern. Solana does not use EVM 4-byte function selectors. Solana uses instruction discriminators (8-byte anchors for Anchor programs or custom layout). The specific signal methodology (selector sequence + calldata shape matching EVM exploit templates) is EVM-architecture-specific per U10.
