Cause (Documented platform behavior): v3 aligned OSS with the Platform API: entity IDs go top-level for add()/delete_all() but inside filters for search()/get_all().
Fix status: documented_behavior
Other error fragments:
- filters must contain at least one of: user_id, agent_id, run_id.

Problem details
- Observed symptom
- Memory retrieval tool calls start failing after upgrade; agents lose recall.
- Context

solution · Revision 1
Proposed fix: [Mem0 v3] m.search(query, user_id=...) raises "Top-level entity parameters {...} are not supported in search(). Use filters={'user_id': '...'} instead."
Recommended action: Call m.search(q, filters={'user_id': uid}) and m.get_all(filters={'user_id': uid}); keep user_id top-level for add().
