Take-profit ladders, closed by a keeper that cannot steal

A maker whose capital earns while it quotes
The maker's USDC sits in steakUSDC. A solvency guard caps every quote at what the vault can actually redeem, and settlement hooks redeem on fill and re-deposit on receipt, inside the swap. Return = vault APY + spread.
What the guard does to a quote
No guard · priced against 10M virtual reserves
Guard, Sep 5 · capped one reserve, broke the price
Guard, now · caps depth, keeps the price
