The AO3 doesn't 'change' tags - except in very rare instances. So if you tag a fic as 'Harry Dresden' for the books, it'll stay that way, but it'll be syn'd to his full name.


But the canonical we wranglers choose shows up in that damn filter - you know that one that looks like a table of contents to your works but really isn't because it lists every direct canonical and indirect meta-tag associated with any single tag you, the author, put on your story? One day the issue will work its way up the coders to do list and we'll be able to remove it if we want. I hope.
