Scalable Time Series Compound Infrastructure

Summary: Time Series Compound objects (TSC) with similarity semantics and compact, misalignment-resistant representations for interrelated series. Sloth, a TSC-aware index/storage, yields up to 10x faster TB-scale queries and ~70% higher mAP for approximate kNN. (summarized by gpt-5-nano on Feb 09 2026)
