Part of switching to the [abbreviations we've decided to use](https://docs.google.com/document/d/1RRYMm42osyqhI2LyjrjockYCutQ5dOf8Abu50kTrkX0/edit?resourcekey=0-kHyqOESbOHmzZphUbtLrTw#heading=h.pph7i5m5un7q). I will rename files in a follow-up PR. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
