A Stream Deck has five session keys. I usually have six or seven Claude Code sessions running. When a new one shows up, the muscle memory test isn't "does the right session get evicted", it is "do the four survivors stay on the keys they were already on."

LRU stands for “least-recently used,” the standard cache-eviction policy: when you need to make room, drop the entry nobody has touched in the longest time.)
