Things broken on purpose

I write smaller commits than I used to. The commits are uglier in isolation and much easier to read in sequence.

There's a kind of premature optimization that comes from imagining a future team. "What if someone needs to swap this out?" Often, no one does.

Caches solve a problem and create three new ones: invalidation, observability, and the slow drift between what the cache thinks is true and what the source thinks is true.
