canonical is a tiny kinetic sci-fi piece following the discovery of a transubstantiation in the timeline, which changed the course of a person's life. This isn't surprising for the narrator, having changed reality in the past themselves (implied for the worst) and now working to catch others doing the same. Though there's no resolution to the why or the how (or any question really), the piece does set up the mystery and setting, and potentially conflicts.
Though, part of my kinda wished it would have ended at this sentence: everyone else fabricates evidence, what’s a little reality on top?
This reminded me a bit of the Temps Commission in The Umbrella Academy and in a way Looper.
