Scale Learning and Reasoning Across Heterogeneous Gradients and Semantics

Proposes Bi^2Clip, a coordinate-wise bi‑directional clipping optimizer that approximates adaptive preconditioning without storing per‑client statistics (two clipping thresholds, SGD‑level memory) and provably handles heavy‑tailed gradient noise (alpha‑moment setting) while matching Adam‑like performance on GLUE, CIFAR‑100 ViT and SQuAD/Qwen2.5. Adds staleness‑aware aggregation that downweights stale updates to improve asynchronous convergence. Introduces federation‑over‑text where clients share metacognitive summaries to iteratively build an insight library (tested across ~8 math benchmarks and ~20–30 paper subareas), reducing token generation and improving accuracy.
