Risk Summary:

The pull request has a high risk score of 80, driven by predictors such as "Sum Bug Reports Of Files" and "Delta of Executable Lines." Historically, PRs with these predictors are 114% more likely to cause a bug than the repository baseline. Although the repo's predicted bug trend is decreasing, the presence of 4 file hotspots suggests elevated caution.

Note: The risk score is not based on semantic analysis but on historical predictors of bug occurrence in the repository. The attributes above were deemed the strongest predictors based on that history. Predictors and the score may change as the PR evolves in code, time, and review activity.

Around here is where I thought "we have a lot of noise related to these types; would it help to have mz_arrange flavors absorb that complexity?". I don't know if/that it would, but there is an upfront tax to figuring out what to call (perhaps: great, don't add arrangement building operators folks. :D).

I read through everything, and superficially it checks out. I saw one case of a potential bug, though .. once I saw it I realized that there could be other moments like it.
