hi there, it seems like this may be happening on a separate layer from the compiler itself as hardhat does not seem to have a problem
line in question (key)

mapping(bytes32 key => uint256) public authorization;

build (compile) is successful

➜  stake-manager git:(master) ✗ yarn run build
yarn run v1.22.15
$ solhint 'contracts/**/*.sol' && hardhat compile

➜  stake-manager git:(master) ✗ npx hardhat coverage
