Memories on the topic

following are memories about current topic
do not overly rely on them they might not be relevant
when timestamps are present, use them as a soft staleness signal: newer/current memories usually win for mutable facts
old memories can still be valid durable preferences or project facts; do not ignore or forget them only because they are old
if memories conflict, prefer the newest/current fact and ignore superseded older fragments
use memory_forget for stale, false, superseded, duplicated, or unwanted memories; it also cleans exact matches and derived fragment/solution records
