## Executive Summary
Federated fine-tuning with low-rank adaptation (LoRA) reduces communication and computational overhead by training and exchanging compact trainable LoRA.

## Why It Matters (Strategic Analysis)
Heterogeneous client networks typically bottleneck federated parameter-efficient tuning due to uniform model rank requirements. RBLA+ establishes compute-aware adapter extraction that preserves model performance while scaling edge client participation.
