Rebalance without a gift to the sandwich

Weights drift as prices move. The curator may post a new target inside the same caps, after a delay. Execution is a batch or a TWAP. There is a slippage ceiling the curator cannot switch off.

A single swap through a thin pool on Robinhood Chain is visible in the mempool. The loss lands on holders. The bound exists so a rebalance that cannot fill cleanly simply does not fill.
