📋 Review 摘要

PR 概述：为 XPU 增加 prefill-only / decode-only profiling 入口，并在 XPU MoE 中支持随机 gate 输出做专家均衡 profiling。
变更范围：fastdeploy/envs.py、XPU MoE backend、XPU model runner / worker。
影响面 Tag：XPU OP FDConfig

问题

级别	文件	概述
🟡 建议	fastdeploy/model_executor/layers/backends/xpu/moe/fused_moe.py:318	profiling balance 路径在 MoE 前向中先计算真实 gate，再从 NumPy 构造随机张量，profiling 结果会混入额外 CPU 随机数与拷贝成本
🟡 建议	fastdeploy/worker/xpu_model_runner.py:1512	profile 环境变量校验使用 assert，Python 优化模式下会被跳过，非法配置会继续写入输入和 block 表

历史 Findings 修复情况

Finding	问题	状态
F1	FD_XPU_PROFILE_PREFILL=1 使用默认参数会直接失败。	✅ 已修复
F2	profile 路径手写的 KV block id 没有校验实际 cache 容量。	⚠️ 仍存在

📝 PR 规范检查

标题符合 [XPU] 官方 Tag 要求。PR 描述保留了模板结构，但 Motivation、Modifications、Usage or Command、Accuracy Tests 内容为空或仅模板占位，需要补全为可审查内容。

总体评价

本轮按风险优先审查了新增 XPU profile 执行路径和 MoE gate 变更。未发现需要阻塞合入的确定性问题，但 profiling 结果可信度和运行时校验方式建议在合入前修正。
