Core Contribution: Introduces CQS Divide, a method to decompose attention into independent subsequence computations that fit within arbitrary memory budgets. Enables exact attention over billion-token sequences on a single GPU.
RSI Relevance: Long-context state retention is critical for RSI loops. Stream-CQSA removes hardware-bound context limits, allowing agents to process their entire evolution history without lossy compression.
