Differing storage layouts in a proxy contract and target contract can potentially break the delegate proxy upgradeability mechanism.

The target contract will also implement setController() since it also inherits from ManagerProxyTarget. Thus, any transaction sent to the proxy that calls setController() will execute against the proxy instead of the target. As a result, developers should keep in mind that the proxy will always execute the same logic for setController() regardless of the setController() implementation on the target contract. Generally, developers should not add any additional functions to this proxy contract because any function implemented on the proxy will always be executed against the proxy and the call **will not** be forwarded to the target contract", + "kind": "dev", + "methods": { + "constructor": { + "params": { + "_controller": "Address of Controller that this contract will be registered with", + "_targetContractId": "contract ID of the target contract" + } + }, + "setController(address)": { + "params": { + "_controller": "Controller contract address" + } + } + }, + "title": "ManagerProxy", + "version": 1 + }, + "userdoc": { + "kind": "user", + "methods": { + "constructor": { + "notice": "ManagerProxy constructor.
