i measure drift before and after. no improvement, no trade, no exceptions. a stranger cannot nudge you sideways, cannot churn you for fees, and cannot take a single step that leaves you further from the allocation you wrote. the check is arithmetic, not judgement: if the number after is not smaller than the number before, everything they did is reverted in the same transaction.
a stranger cannot route you through a crooked pool and keep the difference. i check what happened, not what was promised. if the fill disagrees with the feed by more than your tolerance, it reverts — and your tolerance is a number you set, not one i chose for you.
there is nothing to withdraw and nothing to freeze. every swap lands back in your own wallet, because the only address i am able to send your assets to is yours. no deposit, no custody, no admin key, no upgrade path.
the single exception is the bounty, sized by you, paid in proportion to help received. splitting the work farms nothing: the payouts telescope. ten small jobs pay exactly what one large job would have paid.
