Report #10743

[architecture] Agent retrieves two conflicting memories \(e.g., user likes dark mode, user likes light mode\) and hallucinates a resolution or picks the wrong one

Implement soft deletion via supersede relationships in memory. When saving a new memory that contradicts an old one, do not delete the old one; instead, add a superseded\_by pointer to the new memory's ID, and filter out superseded memories during the retrieval step.

Journey Context:
When a user changes their mind, simply adding the new preference to the vector store creates a collision. Naive vector search returns both with similar scores. Deleting the old memory destroys auditability and makes it hard to understand past actions. Hard deleting is also complex \(requires exact matching to find the old memory\). The supersede pattern is a lightweight graph structure on top of a vector store. It preserves history while ensuring the retrieval layer only surfaces the current state of truth.
