★ Public initialize() without initializer modifier
SUNSwap (sun.io)'s assessment for RD-F-022 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
SunswapV2Pair.initialize() is gated by require(msg.sender == factory). This is the standard Uniswap V2 factory-check pattern — functionally equivalent access control; factory only calls initialize() once at CREATE2 pair-creation time. No exploitable unprotected initializer.

Methodology #
Determine whether any implementation contract exposes `initialize(…)` without the OpenZeppelin `initializer` modifier or equivalent initialization lock.
