| ### Specification | ||
|
|
||
| If a cname is found on a name, all records that are unset will be expected to proxy through the specified cname's records. Records that are already set on the resolver will ignore the cname. |

This should clarify that it's the resolver's reponsibility to implement CNAME functionality, not the client.

| event CNameChanged(bytes32 indexed node, string name); | ||
| function cname(bytes32 node) external view returns (string memory); |

I think we need to make a decision here: Either cname takes a node and doesn't implement CCIP-Read and wildcards (so only onchain names can be CNAMEd to), or it takes a DNS-encoded name and does implement CCIP-Read and wildcards. The latter is the more future-proof option, but this implementation requirement needs to be called out.

| bytes memory currentAddr = versionable_addresses[recordVersions[node]][node][coinType]; | ||

| if(currentAddr.length == 0 && cname.length != 0){ |

This will have to be a lot more complex to support CCIP Read and wildcards.
Perhaps we should just implement a canonical CNAME resolver mixin instead of writing a spec?
