Looks interesting. Like that the author modeled the failure scenario first before the correct one, it’s instructive. As other commenter pointed, a small typo in the title.
Yes, any analysis after an incident has the benefit, and bias, of hindsight.
But I see this post less as an incident analysis and more as an experiment in learning from hindsight. The goal, it seems, isn’t to replay what happened, but to show how formal methods let us model a complex system at a conceptual level, without access to every internal detail, and still reason about where races or inconsistencies could emerge.
