Struct ZeroAmount 

pub struct ZeroAmount;

PaymentPool.openPool reverts this when the requested deposit — or the balance delta actually received, under a fee-on-transfer token — is zero. Declared here only for its 4-byte selector, so the classifier needs no live contract binding.

This selector is NOT unique to openPool: PaymentPool.topUp reverts it too, and FeeRouter, CapacityBond and BuybackBurner each declare the identical argument-less signature, so all five share one 4-byte selector. Safe here only because PoolOpenFailureReason::classify_revert_data is called on the open path alone; widening its use would need this checked. Custom error with signature ZeroAmount() and selector 0x1f2a2005.

error ZeroAmount();
