      "insight": "The 1% swap fee on both legs (~4 ETH total) exceeds the IL from repositioning a single anchor traversal. With AW=50 (anchorSpacing=3600 ticks), the anchor is wide and IL per tick is small. Fee income dominates decisively."

      "insight": "Multiple small cycles don't compound IL faster than fee income. Each buy adds ~0.5 ETH in fees to LM (1% of 50 ETH). The floor position consistently blocks sell pressure. The 1% fee acts as a friction ratchet that always benefits the LM."

Optimizer shift created tight anchor (AW=11, ~175 ETH) easy to push through, but floor (95% of ETH, 200 ticks wide, liq=2.04e26) was impenetrable. Fatal flaw: KRK needed for >91% staking can only come from the pool, depositing massive ETH."

The 1% fee moat, floor position defense (75-95% of LM ETH in 200 ticks), ETH-neutral recenter, directional VWAP defense, and the chicken-and-egg problem (KRK acquisition requires ETH deposit) provide layered defense.",
