chunked tables: a key is unique across its map and the slot's own, not interned - a slot keeps row i's key in its own buffer i, rewritten when the slot is refilled (interning ~92k map-unique keys as a player walks would fill the bounded intern table and keep them all); ludicc --check refuses a key written in two of a map's chunk files, naming both; reseeded
