📋 Review 摘要

PR 概述：调整 FP8 Triton MoE 在小 token 场景下的 tiling 配置。

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。

diff-cover --fail-under=80	PR 差异覆盖率未达到 80%，job 以 exit code 9 失败

  if [ "$COVERAGE_EXIT_CODE" -eq 9 ]; then ... exit "$COVERAGE_EXIT_CODE"

• 根因摘要: 新增 MoE 配置分支缺少差异覆盖

PR 仅修改 fastdeploy/model_executor/layers/moe/fused_moe_triton_backend.py，在 token_num <= E 路径下新增了 token_num <= 16、token_num <= 32 和其余小 batch 的配置分支。CI 快速日志给出的失败码是 9，而该 workflow 明确把 diff-cover --fail-under=80 失败映射为 9，因此本次失败更符合新增代码差异覆盖率不足，而不是单测断言或环境异常。深度日志未返回 diff_coverage.json 的具体百分比，所以置信度标为中。

修复建议:

1. 补充覆盖 fastdeploy/model_executor/layers/moe/fused_moe_triton_backend.py:750-776 新增分支的单测，至少覆盖 token_num <= 16、17 <= token_num <= 32、token_num > 32 且 token_num <= E 三种路径。
2. 可在现有量化/MoE 测试中 mock tritonmoe_preprocess_func 和 Triton kernel 调用，断言传入的 BLOCK_SIZE_M、BLOCK_SIZE_N、num_stages 符合预期，避免依赖真实 GPU kernel 才能覆盖配置选择逻辑。
