2026 April - 34 articles

Cover Story: This paper introduces Historical State Reconstruction (HSTR), a framework that pre-compiles unstructured SEC filings into structured, bitemporal states. Unlike RAG or memory-based agents, HSTR decouples offline extraction from online inference, enabling low-latency reconstruction via snapshots and deltas. Evaluated on major S&P 500 companies, the system dramatically accelerates context retrieval and compresses verbose filings into compact, prompt-ready states while guaranteeing strict temporal integrity, free of look-ahead bias for regulatory-compliant backtesting. View this paper
