Most agent memory systems treat stored facts linearly. There’s no sense of when a fact was true, whether it’s been superseded, or how to reason about time at all.
This is the story of how we diagnosed the problem, found the research, and built a production fix in Node.js and SQLit, no Python, no subprocess, no academic overhead.
Received a great question from a reader along these lines:
“Temporal reasoning is the one I’d love to see more research on — most retrieval systems treat memory as a flat bag of facts and the agent has no way to know that a fact from yesterday supersedes one from last month”
Which interesting question sent us down a rabbit hole through Arxiv late in the evening before dinner.
