Pre-Liquidation Clearing

Pre-liquidation uses stricter rules than HL official liquidation to protect users

  1. Aggregator monitors HL margin health
  2. When near liquidation threshold, Aggregator uses reduce-only IOC/limit via Agent Wallet to unwind at better price
  3. User preserves equity and saves memory
