NodeRegistry - In3Node memory n is never used
NodeRegistry `In3Node memory n` is never used inside the modifier `onlyActiveState`.\\n```\\nmodifier onlyActiveState(address \\_signer) {\\n\\n    SignerInformation memory si = signerIndex[\\_signer];\\n    require(si.stage == Stages.Active, "address is not an in3-signer");\\n\\n    In3Node memory n = nodes[si.index];\\n    assert(nodes[si.index].signer == \\_signer);\\n    \\_;\\n}\\n```\\n
Use `n` in the assertion to access the node signer `assert(n.signer == _signer);` or directly access it from storage and avoid copying the struct.
```\\nmodifier onlyActiveState(address \\_signer) {\\n\\n    SignerInformation memory si = signerIndex[\\_signer];\\n    require(si.stage == Stages.Active, "address is not an in3-signer");\\n\\n    In3Node memory n = nodes[si.index];\\n    assert(nodes[si.index].signer == \\_signer);\\n    \\_;\\n}\\n```\\n
