A vector search module is only part of conversation memory
Retrieval becomes useful when information is saved, scoped to the right person and used in the live workflow.
A conversation-memory investigation examined what was embedded and whether the normal message flow actually saved and retrieved that context.
Start with the unit of meaning
The implementation embedded message-level text and searched it by vector similarity. Separate terminology extraction did not make this word-level search. Understanding the retrieval unit comes before judging whether the results fit the task.
Trace how memory gets populated
The review found no observed persistence call from the normal message handler into the learning function. A search module cannot retrieve useful history if the application never supplies it. This was an integration gap identified in investigation, not a completed production fix.
Check identity across boundaries
A mismatch between context keys could leave an identity missing and skip retrieval. Follow the identity from incoming message to search call, alongside the stored data and returned context.
What the investigation established
The review clarified the retrieval unit and identified possible connection gaps. It did not establish reliable end-to-end behavior. A follow-up should exercise saving a message, retrieving it for the intended identity and using it in the answer.
