Report #54490

[architecture] Agent memory grows unbounded and degrades retrieval precision

Implement explicit memory deletion or overwriting mechanisms. When a memory is updated \(e.g., 'user lives in NY' -> 'user moved to CA'\), delete the old embedding, don't just append the new one.

Journey Context:
Append-only memory stores suffer from semantic collisions. If both 'lives in NY' and 'lives in CA' exist, retrieval might pull the wrong one based on embedding distance. Agents need CRUD operations on memory, not just Create and Read. Tradeoff: requires exact entity tracking to know \*which\* memory to delete, adding architectural complexity, but necessary to prevent state drift and hallucination from contradictory memories.
