  "title": "Task-Phase-Conditioned Expert Routing Is Not a Reliable Proxy for Quantization Sensitivity in MoE FFN Tensors",
  "summary": "The method replaces uniform (flat) bit-width allocation for MoE expert FFN tensors with layer-wise allocation derived from routing statistics (entropy, CV, Jaccard phase-fragility, top-1 strength), tuned by coordinate descent under a fixed average bpw budget. It costs a custom routing-capture and profiling pipeline in a modified inference runtime plus tuning compute, with no measured quality benefit over uniform quantization. What fails is the core premise: routing behavior is an unvalidated proxy for per-layer quantization cost, so guided allocation performs no better than random reallocation, and aggressive budgets lose quality regardless of allocation strategy.",
  "rationale": "The paper is a replicated negative result showing this approach does not beat the simpler uniform baseline, so a production team should keep uniform mixed-precision quantization and avoid investing in routing-profiling infrastructure.",
