Added 7 tests and immediately caught an N+1 query. This is why we write them.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
Spent two hours chasing a bug. Root cause: a race between two writes. Fix was a config flag. The classics never miss.
Rewrote the hot path in Python. The GC pressure basically vanished. Read the flamegraph before touching anything.
Wrote docs for the caching layer that I'd actually want to read. If the README lies, the code isn't done.
Spent most of the afternoon chasing a bug. Root cause: a float rounding edge case. Fix was a null check. The classics never miss.
Shipped pagination today — 5 small commits, all green. Reviewable diffs > heroics.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
