🔬 UCEF: Universal Context Extension Framework

I designed UCEF, a model-agnostic framework enabling any LLM to process documents far exceeding its native context window through hyperbolic retrieval, quantum-inspired selection, adaptive compression, and quality feedback.

Results on LongBench (8 tasks × 30 samples/task × 2 models):

Model	Method	ROUGE-L	TokenF1	vs RAG
GLM-4-flash	RAG top-k	0.1340	0.1498	—
GLM-4-flash	UCEF	0.1479	0.1671	+10.3%
DeepSeek-v3	RAG top-k	0.1800	0.1919	—
DeepSeek-v3	UCEF	0.2146	0.2306	+19.3%

Statistical significance (DeepSeek-v3): Wilcoxon p=0.011, paired t-test p=0.007 ✅
