What it follows
A phrase can become a song title, a fictional district can acquire police and transit, a character can disappear for years and return under altered conditions, a record can behave like a book, and a joke can become an actual live project. The wiki follows those movements rather than sorting everything by publication platform.
Evidence
Some connections are literal: repeated language, chronology, credits, explicit process notes, recurring names, shared locations. Others are interpretive. The site tries not to pretend those are the same thing.
What it is for
Follow a phrase, character, district, record, image, argument or joke until it turns into something else. It is also an external memory for a body of work too large to remember cleanly.
NO MASTER KEY
The wiki is not a decoder ring. Parallel geographies remain parallel. Ambiguities can remain ambiguous. Misreadings may themselves become productive. An explanation is useful only until it starts flattening the thing it explains.
