Not sure where to start? Try these four experiments.

01

Deposit 100 TOKEN, borrow near 75% LTV, and record the safety room that remains.

02

Advance interest while price stays flat, watch health fall, then repay part of the debt.

03

Lower the oracle price below the liquidation line, run the keeper, and follow credits and TOKEN.

04

Drop the market price while keeping the old oracle, then compare when risk truly appears.
