Mem0 Auto-Resolves Memory Conflicts for You — Until It Silently Deletes One You Still Need

Mem0’s add() pipeline extracts facts from text, compares them with stored memories, and chooses among ADD, UPDATE, DELETE, or NONE.

The failure mode is that preferences valid in different contexts can be flattened into a generic contradiction, causing one to be deleted without warning.

In long-lived agents, silent deletions can erase important user context and lead to incorrect behavior without errors or logs.

The proposed fix is to make scope explicit in keys and add an audit wrapper so distinct preferences can coexist safely.
