Struct registerMappingSstoreHookCall 

pub struct registerMappingSstoreHookCall {
    pub target: Address,
    pub rootSlot: FixedBytes<32>,
    pub callback: FixedBytes<4>,
}

Registers a callback after exact mapping-element SSTOREs rooted at rootSlot in target’s effective storage account.

The callback signature is function(address account, bytes32 computedSlot, bytes32 rootSlot, bytes32[] keys, bytes32 oldValue, bytes32 newValue) external; keys are raw words in root-to-leaf order. Only complete 64-byte Keccak chains observed after the latest mapping hook registration for target in the current top-level execution match; provenance is cleared between top-level executions. Resolution follows the complete chain to its terminal root and ignores registered intermediate hashes. Offsets, incomplete or unknown chains, hashes computed before registration or in an earlier top-level execution, and source layouts do not match. The contract that calls this cheatcode receives the callback. Registration persists across reverts and replaces the same target/root callback; callback state rolls back with its enclosing context, callback reverts propagate, and hooks are suppressed throughout callback subtrees. The callback must authenticate msg.sender == address(vm) to prevent external spoofing. Raw and mapping SSTORE hooks conflict per target, while multiple mapping roots may be registered. Function with signature registerMappingSstoreHook(address,bytes32,bytes4) and selector 0x12d14123.

function registerMappingSstoreHook(address target, bytes32 rootSlot, bytes4 callback) external;
