📋 Review 摘要

PR 概述：调整 FP8 Triton MoE 在小 token 场景下的 tiling 配置。
变更范围：fastdeploy/model_executor/layers/moe/fused_moe_triton_backend.py
影响面 Tag：[OP] [Quantization] [Optimization]

标题缺少官方 Tag，PR 描述仍是模板占位内容，未填写 Motivation、Modifications、Usage or Command、Accuracy Tests 和 Checklist 状态。建议替换为以下内容。

标题建议（可直接复制）：

• [Optimization] Tune FP8 Triton MoE small-token config

PR 描述建议（点击展开，可直接复制）

## Motivation
Tune the Triton MoE FP8 kernel configuration for small-token workloads to use smaller M/N tiles and adjusted pipeline stages.

## Modifications
- In `fastdeploy/model_executor/layers/moe/fused_moe_triton_backend.py`, refine the `Wfp8Afp8MoEMethod.apply` config when `token_num <= E`:
  - `token_num <= 16`: use `BLOCK_SIZE_M=16`, `BLOCK_SIZE_N=64`, `num_stages=4`.
  - `token_num <= 32`: use `BLOCK_SIZE_M=32`, `BLOCK_SIZE_N=64`, `num_stages=3`.
  - `token_num > 32` and `token_num <= E`: keep `BLOCK_SIZE_M=64`, `BLOCK_SIZE_N=128`, and set `num_stages=3`.

总体评价

本轮按风险优先审查了 FP8 Triton MoE 小 token 配置分支，以及该配置传入 preprocess 和两次 fused MoE GEMM kernel 的调用关系；未确认到会改变路由、shape、scale 或写回语义的阻塞性问题。建议补齐 PR 标题和描述中的规范信息，尤其是性能/精度验证结果或未提供的原因。

用例	错误摘要
fastdeploy/model_executor/layers/moe/fused_moe_triton_backend.py	新增 FP8 MoE Triton 配置分支 diff coverage 未达到 80%，CI 以 exit code 9 失败

.github/workflows/_unit_test_coverage.yml:387-404 COVERAGE_EXIT_CODE=9 时输出 Coverage generation failed 并 exit 9

• 根因摘要: 新增 FP8 MoE 分支缺少 diff 覆盖
  PR 仅修改 Wfp8Afp8MoEMethod.apply 中 token_num <= E 下的配置选择，新增了 token_num <= 16、token_num <= 32、以及更大 decode token 的三段配置。现有 tests/layers/test_fused_moe_triton_backend.py 里 Wfp8Afp8 apply 用例只执行 1 token 路径，未覆盖新增的 17 <= token_num <= 32 和 33 <= token_num <= E 分支，因此 diff-cover 低于 80%。本次深度日志未返回 unittest_details/log_file_path，未发现具体 pytest 断言失败证据。

修复建议:

1. 在 tests/layers/test_fused_moe_triton_backend.py 为 Wfp8Afp8MoEMethod.apply 增加参数化测试，构造 num_local_experts >= 64，分别用 16、32、64 个 token，断言首次 kernel 调用的 BLOCK_SIZE_M、BLOCK_SIZE_N、num_stages 等配置。
2. 补充 token_num > E 的默认配置保持不变测试，避免后续配置优化误伤 prefill/default 路径。
