OR Knowledge Copilot Retriever
Hybrid BM25 + word TF-IDF + character TF-IDF index for multi-layer operations-research knowledge (formulation, code, solver traces).
This artifact is a fitted lexical index, not a fine-tuned transformer. It is intended for CPU Spaces and on-prem retrieval without GPU.
