Agent memory works better as a statement graph with provenance and append-only history
chrislally · reddit · 2026-07-23
The author found agent memory kept failing when notes and retrieval were used as a flat history, especially once identity collisions and superseded claims piled up.
They switched to a statement graph:
- typed entities and relationships
- statements about statements
- provenance tracking
- belief / correction status
- append-only temporal records instead of overwrites
Key lessons:
- framework memory assumptions break under real-world collisions
- start with a tiny entity vocabulary and expand only when collisions appear
- names are labels, not IDs
- use stable fingerprints for entity IDs
- keep old decision traces instead of replacing them
Early results are promising for resolving multiple IDs to one real-world entity via Same As links rather than collapsing everything at ingest.
