Report #102584

[architecture] Memories are arbitrary free-form strings that the model must parse inconsistently at retrieval time.

Store memories with a lightweight schema—entity, relation, timestamp, source, confidence, expiration—and expose separate blocks for semantic facts, episodic traces, and scratchpad/working state.

Journey Context:
Unstructured text is flexible but opaque: the same fact appears in a dozen phrasings, and retrieval cannot distinguish observation from inference. Letta's memory blocks are typed, labeled sections that the agent learns to edit; Zep/Graphiti stores temporal facts as structured graph edges. A schema lets you update facts in place, detect contradictions, and render memory consistently into the prompt. The overhead is small and pays off in reliability, especially when memory is shared across agents or audited by humans.
