Time is Not a Label: Continuous Phase Rotation for Temporal Knowledge Graphs and Agentic Memory

ArXi:2604.11544v1 Announce Type: cross Structured memory representations such as knowledge graphs are central to autonomous agents and other long-lived systems. However, most existing approaches model time as discrete metadata, either sorting by recency (burying old-yet-permanent knowledge), simply overwriting outdated facts, or requiring an expensive LLM call at every ingestion step, leaving them unable to distinguish persistent facts from evolving ones. To address this, we
