Why It Matters
**Why it matters:** This work reveals that standard multiple‑choice benchmarks hide a fragility in compressed models — pruning can preserve surface‑level accuracy while eroding true reasoning and interpretability. For industry, it signals that lighter, deployment‑friendly LLMs may still fail in real‑world, open‑ended tasks, compelling a shift toward benchmarks that test genuine understanding rather than test‑oracle exploitation.
