getbalancesnow includes anonmempoolfield undermine, reporting the net balance of wallet transactions that are not in the mempool (e.g. due to too low a feerate, too many unconfirmed ancestors, or a too-largeOP_RETURNoutput). This value is always negative, and is typically an over-estimate since it accounts for coins being spent but not for change outputs returning to the wallet (which are also outside the mempool). Without this field, funds involved in non-mempool transactions could appear to go missing from the wallet balance. (#33671)
