delegatecall with user-controlled target

SUNSwap (sun.io)'s assessment for RD-F-012 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Uniswap V2-derived AMM pattern does not use delegatecall to user-controlled targets. V4 hooks call external hook contracts but hook address is fixed at pool initialization (not user-supplied per-tx). No user-controlled delegatecall target found in core contracts.
