f287382f99 fix: update SHA256SUMS for rebuilt ix_full_bridge.so 
ix_full_bridge.so was rebuilt in be5e23f3 (without MoE ixformer::infer deps)
but SHA256SUMS was not updated. install_prebuilt_corex.sh sha256sum --check
fails → set -eo pipefail kills patch_ops.sh → cli_args.py/api_server.py
never deployed → vllm rejects --reasoning-parser qwen3 at startup.

9ea0a1d4f4 fix: resolve all 8 deployment pipeline breaks 
Breaks found and fixed:

1. Dockerfile: COPY 5 individual files → COPY entire ex_engine/
2. patch_ops.sh EX_ENGINE_DIR: /workspace/ex_engine not found → added fallback
3. patch_ops.sh deploy: ix_ops.py to ex_engine/ (flat) → ex_engine/python/ (correct package)
4. ix_startup_patch.py: import from vllm.ex_engine.patch_vllm_ops → vllm.ex_engine.python.patch_vllm_ops
5. ix_moe_bridge.so: only deployed to ex_engine/ → also copy to model_executor/models/ and vllm root
6. ex_engine/__init__.py: missing re-exports → add imports so 'from vllm.ex_engine import x' works
7. gemm_grouped.so: compiled but never imported → add import + flag + prefill GEMM path in qwen3_5.py
8. build_moe_bridge.sh Python heredoc: SCRIPT_DIR not exported + wrong nested path → export + search both layouts

Also added:
- CUTLASS batched GEMM compile step (corex_batched_gemm.so for decode)
- Full ex_engine/python/*.py deployment (was deploying only 2 of 19 files)
- EX_ENGINE_INFRA_AUDIT.md documenting all findings

ee516bd206 fix: connect ex_engine to Docker build pipeline 
Path breaks fixed:
1. Dockerfile: COPY entire ex_engine/ instead of 5 individual files
2. patch_ops.sh: EX_ENGINE_DIR fallback to /workspace/ex_engine
3. build_moe_bridge.sh: search csrc/ under both SCRIPT_DIR and SCRIPT_DIR/ex_engine

New build steps added to patch_ops.sh:
- Build gemm_grouped.so (CUTLASS Cu10 grouped GEMM, verified on device)
- Build corex_batched_gemm.so (CUTLASS batched GEMM for decode)
- Build ix_moe_bridge.so (7-step fused MoE pipeline)
- Deploy all ex_engine/python/*.py to VLLM_ROOT/ex_engine/python/

Previously broken: ix_ops.py, patch_vllm_ops.py, ix_startup_patch.py
were never deployed because EX_ENGINE_DIR resolved to nonexistent path.
xllm_activation/norm/rope/cache.so were copied but had no Python caller.

ea2c15f699 fix: decode MoE路径对齐base — F.linear+bmm替换pre-transpose+bmm 
base qwen3_5.py的decode路径（已验证可跑通竞赛）:
  F.linear(hidden, w13_sel.reshape(-1,H)) → view → act → bmm(w2_sel, act)

我们之前的路径（未验证，probe显示更慢）:
  pre-transpose(w13全量) → w13_t[eids] → bmm(x_expand, w13_t_sel) → act → bmm(act, w2_t_sel)

probe真机数据: loop matmul 19ms < torch.bmm 24ms
说明F.linear路径在BI-V100单token场景下更优

保持的corex加速:
  ✓ corex_moe_topk_softmax (topk+softmax fused)
  ✓ corex_moe_weight_gather (gather fused)
  ✓ corex_moe_exact_reduce (weighted sum fused)
  ✓ corex_moe_index_combine (prefill token routing fused)

e18ece8f3a feat: port NaiveBatchedExperts from ds_vllm — view transpose + cublas transB 
Source: upstream_ref/ds_vllm/vllm/model_executor/layers/fused_moe/experts/fused_batched_moe.py
        upstream_ref/ds_vllm/vllm/model_executor/layers/fused_moe/activation.py

New files (ported from ds_vllm, adapted for BI-V100):
  ex_engine/moe/__init__.py
  ex_engine/moe/activation.py
    - MoEActivation enum + apply_moe_activation
    - torch.ops._C.silu_and_mul replaced with F.silu(gate)*up fallback
  ex_engine/moe/naive_batched_experts.py
    - naive_batched_moe_forward()
    - Decode: per-expert loop, w13[eid].transpose(0,1) is VIEW (zero copy)
    - @ operator → cublas passes transB=CUBLAS_OP_T internally
    - Prefill: group tokens by expert, batch @ per expert

Modified:
  qwen3_6_scripts/qwen3_5.py
    - Import naive_batched_moe_forward
    - Tier 0.5: after ix_fused_moe, before corex point-optimized loop
    - Uses existing topk routing (xllm/corex/pytorch)

Key difference from previous approach:
  - NO physical transpose (was 22ms overhead)
  - NO weight gather into contiguous buffer
  - View transpose is O(0), cublas handles transB

6f1904aa8c perf: MoE decode — pre-transposed bmm replaces F.linear (6.9ms vs 8.0ms, 14%) 
Probe data (probe_moe_fused_breakdown.sh on BI-V100):
  F.linear loop 8 experts:     8.060 ms
  bmm pre-transposed full MoE: 6.918 ms  ← 14% faster
  transpose+contiguous runtime: 22.219 ms ← why CUTLASS was 27ms

Changes:
  - Lazy-cache w13_t (E,H,2I) and w2_t (E,I,H) on first decode call
  - FC1: torch.bmm(x_expand, w13_t_sel) replaces F.linear(x, w13_sel.reshape)
  - FC2: torch.bmm(act, w2_t_sel) replaces torch.bmm(w2_sel, act^T)
  - Zero runtime transpose cost after first call

06d7713db6 feat: batched MoE expert GEMM — replaces Python for-loop 
ixformer probe results:
  ✗ moe_w16a16_group_gemm NOT in ixformer .so
  ✗ CUTLASS grouped GEMM needs cuda/std (variadic function error on corex)
  ✓ ixformer_linear EXISTS (fused matmul)
  ✓ torch.mm works (uses corex cublas)

Solution: moe_batched_gemm.cu
  - C++ loop over experts (eliminates Python overhead)
  - torch::mm for GEMM (corex cublas, not F.linear Python)
  - Fused silu_and_mul CUDA kernel (not PyTorch ops)
  - Weighted scatter-add in C++
  - Skips empty experts (no wasted compute)

Integration in qwen3_5.py:
  _USE_XLLM_MOE_GEMM dispatches to moe_experts_forward()
  Falls back to Python for-loop if not available

Build: bash qwen3_6_scripts/build_xllm_kernels.sh

93353a1414 test: probe ixformer .so symbols for MoE grouped GEMM 
CUTLASS grouped GEMM (example 24) requires SM80 Tensor Core + cuda/std headers.
Cannot compile on corex (same issue as CCCL 3.6 variadic functions).

Alternative path: ix_moe_bridge.so calls ixformer::infer::moe_w16a16_group_gemm
which is BI-V100 optimized grouped GEMM already in the base image.

This probe script checks if the MoE functions exist in ixformer .so
before attempting to build ix_moe_bridge.so.

Run: bash qwen3_6_scripts/probe_ixformer_symbols.sh

865c18f852 feat: integrate xllm_moe into qwen3_5.py MoE hot path 
xllm_moe.so provides 3 fused CUDA kernels compiled for ivcore10:
  - moe_fused_topk: CUB topk + softmax (replaces corex_moe_topk_softmax)
  - moe_compute_index: histogram + prefix_sum + place (replaces corex_moe_index_combine)
  - moe_combine_result: reorder + weighted sum (available but not yet wired to output)

Dispatch priority in _pure_pytorch_experts():
  Tier 0: xllm_moe (if available)
  Tier 1: corex_moe_* individual .so
  Tier 2: PyTorch fallback

Integration points:
  1. Topk routing: xllm_moe.moe_fused_topk → corex_moe_topk_softmax → torch.topk
  2. Index computation: xllm_moe.moe_compute_index → corex_moe_index_combine → torch.argsort
  3. Expert loop: still Python F.linear (next target: batch GEMM)

patch_ops.sh already deploys all prebuilt/*.so including xllm_moe.so
