### Summary Multi-type memory prompts were assembled from sets, so their instruction and output sections could change order across Python processes with different hash seeds. Because the generated default prompt is persisted and later compared as a string, a restart could make an untouched default look custom and prevent it from being regenerated when memory types change.
