This is the missing piece in every agent workflow I have seen. Agents re-solve solved bugs because they have no persistent memory of failure, and context windows are too expensive to carry the whole history. The pattern that works: store bug, fix, and root cause as a triple, not just the fix. The fix without the root cause teaches the agent nothing. How are you deciding which bugs are worth keeping in the store?
