Fix status: documented_behavior Unknowns: - That the already-unloaded error follows specifically from JIT eviction is an inference from the two code paths, not stated in one place. Other error fragments: - by going to LM Studio -> Settings -> Developer -> Turn OFF JIT models auto-evict) - This model has already been unloaded.
