Thoughts on bridging traditional financial risk models to DeFi liquidity pools?

It strikes me that many of the quantitative risk frameworks we use for market and credit risk in traditional finance feel inherently difficult to adapt directly to the composable and often unaudited smart contract environments of DeFi. Especially concerning is how quickly a black swan event in one protocol can cascade through many others, making standard correlation assumptions seem naive. Does anyone have specific examples or approaches they're seeing to effectively model and stress-test DeFi portfolios beyond basic impermanent loss metrics?
