Attack 4 (2050 ETH): delta_bps=3746 is from extreme slippage through thin liquidity beyond concentrated positions, not just 1% fees. Insight corrected to explain the slippage mechanism. 2. Floor Ratchet: renamed to "initial phase only", insight explicitly notes the 2000-trade oscillation variant is NOT tested here and is tracked as follow-up issue #1082. 3. Added methodology field explaining snapshot-isolation semantics (why lm_eth_after == lm_eth_before). 4. Restored two dropped strategies (discovery WETH consumption, one-way sell) with notes that they are subsumed by other attacks.
