BNB → WATER Adapter

BNB compounding is isolated behind an approved adapter architecture.

Personal vault BNB
      ↓
Approved adapter
      ↓
Pancake-compatible BNB/WATER swap
      ↓
WATER returned
      ↓
Flexible or Locked destination

The vault’s compoundBNB call takes the BNB amount, adapter, minimum WATER output, deadline and destination pool.

The adapter registry controls which adapter addresses are approved. This prevents an ordinary maintenance operator from arbitrarily replacing the swap path.
