MAX_IN_MEMORY_NODES

const val MAX_IN_MEMORY_NODES: Int(source)

Ceiling on entries in the in-memory node index. See NodeIndex.evictedToFit.

An order of magnitude above the largest NodeDB firmware exposes (MAX_NUM_NODES is 100–250 by target), so a legitimately busy mesh never reaches it and only sustained novel-from traffic does.
