** Normalizing HTML URLs
The arcology should route all internal URLs, rewriting any which are not exposed via =ARCOLOGY_KEY= to the [[file:404.org][404 page]]
The arcology should route all internal URLs, rewriting any which are not exposed via =ARCOLOGY_KEY= to the [[file:404.org][404 page]]. the URLs which are =roam:= prefixed are dangling links in my [[file:../knowledge_base.org][Knowledge Base]], they otherwise would be rewritten to a real page and those are turned in to a broken link. I'd like to include some statistics for these at some point so I can have some awareness of the pages people are interested in, but that's not important right now.

=normalize_url/2= is called by the =Regex.replace= in =normalize_urls/1=, the second argument is all we care about, it comes out of the capture in the expression, and is the string of the relative file-name in all likelihood; this is not really consistent and it *is* something that I need to resolve in my [[file:../cce/org-roam.org][org-roam]] and [[file:../org-mode.org][org-mode]] configurations. This is going to have a lot of data-validity issues, and I kind-of wish that it was easier to quickly get an [[file:arcology_roam.org][Arcology.Roam.Link]] from this =page= variable to get to a [[file:arcology_roam.org][Arcology.Roam.Keyword]].
