SwapInputTooLarge

The pool cannot absorb this trade; reduce the amount or split it into smaller steps

The swap's net input after fees exceeds 1000 times the input-side reserve, the pallet's hard per-trade cap. Compare the input amount against the subnet's input-side reserve (TAO or alpha) and split the trade if needed.

Declared by the Swap pallet; it classifies to the semantic code insufficient_liquidity.
