[TRTLLM-15177][test] Wire remaining Kimi K3 MoE unit tests into L0 (Hopper)

[brnguyen2]

Description

Three Kimi K3 MoE unit tests exist in the tree but are referenced by no L0
test list, so they never run in pre-merge CI:

• tests/unittest/_torch/modules/moe/test_kimi_k3_mlp.py
• tests/unittest/_torch/modules/moe/test_kimi_k3_moe_gate.py
• tests/unittest/_torch/modules/moe/test_kimi_k3_situ_and_mul.py

All three are any-CUDA: they exercise the Triton trtllm::situ_and_mul op and
the noaux_tc_op routing op against a torch reference, gated on requires_cuda
only (not SM100/SM103). They are wired into l0_h100.yml (pre-merge, single-GPU)
next to the other MoE-component unit tests, so they add coverage on Hopper
rather than consuming scarce Blackwell pre-merge capacity.

The Blackwell-gated K3 suites (kimi_kda, kimi_k3_attn_res,
kimi_k3_situ_moe, KDA parity) are already wired in l0_b200.yml and
l0_gb300_multi_gpus.yml (landed under this ticket in #17413); this fills the
last gap for the any-CUDA K3 MoE files. Addresses item 1.4 of TRTLLM-15177.

Test-list-only change — no source/API changes.

Test Coverage

The three added entries are the tests themselves. Validated with the repo's
own checker:

python3 scripts/check_test_list.py --validate
# OK: 2051 unique test entries validated.

(also runs as the "Validate test list entries exist in source files (AST)"
pre-commit hook, which passed on commit.)

PR Checklist

• Please check this after reviewing the above items as appropriate for this PR.

Dev Engineer Review

• Added three CUDA-gated Kimi K3 MoE tests to tests/integration/test_lists/test-db/l0_h100.yml.
• Added entries:
  • test_kimi_k3_mlp.py
  • test_kimi_k3_moe_gate.py
  • test_kimi_k3_situ_and_mul.py
• The entries match the H100 pre-merge test scope.
• Test-list validation passed with 2,051 unique entries.
• No source, API, or public entity changes were made.

QA Engineer Review

• Modified tests/integration/test_lists/test-db/l0_h100.yml.
• Added three Kimi K3 MoE test suites.
• Removed no entries.
• Verdict: needs follow-up because CBTS coverage data is unavailable.

Walkthrough

The H100 PyTorch MPI pre-merge test list now includes Kimi K3 MoE unit tests for the MLP, MoE gate, and situ_and_mul components.

Changes

Kimi K3 MoE Test Coverage

Layer / File(s)	Summary
Enable Kimi K3 MoE unit tests tests/integration/test_lists/test-db/l0_h100.yml	Adds the Kimi K3 MoE test section to the H100 pre-merge suite and enables tests for the MLP, MoE gate, and situ_and_mul implementations.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to ef5c8

This change only adds three existing CUDA unit tests to the Hopper pre-merge list, with no product-code changes. It is not merge-ready until the required coverage-scope verdict is supplied or explicitly accepted.
