Report #55027

[architecture] Agent follows an old, superseded instruction or preference because the outdated memory was retrieved alongside newer context, causing contradictory behavior

Implement memory consolidation or reflection: before writing a new memory, search for conflicting existing memories. If a conflict exists, update the existing memory node or tag the old one as superseded. During retrieval, filter out superseded memories.

Journey Context:
Vector databases are append-only by default. If a user says 'I prefer dark mode' and later 'I switched to light mode', both are embedded with high similarity. Retrieving both pollutes the context and forces the LLM to guess which is current. The tradeoff is the write-amplification \(searching before writing\) vs. read-pollution. The right call is paying the cost at write time \(consolidation\) to keep the read path fast and deterministic.
