origin/main fails the device-leakage CI job:
ERROR: DSR REGRESSION in bucket 'vt_ifdef': 33 > baseline 32.
DSR by bucket: kcuda=0, is_cuda=0, cuda_inc=0, vt_ifdef=33 -> total 33
Qwen3_5DenseModel::PrepareLmHeadResident (src/vllm/model_executor/models/qwen3_5.cpp) opened a new #ifdef VT_MARLIN_NVFP4 in the device-agnostic shared layer to guard the Marlin build, taking that file from 26 to 27 in the vt_ifdef bucket. It arrived with PERF-27B-LMHEAD-FP4 (#213, PR #263, merged bc2fa7d9).
Why it landed red. The device-leakage job never finished on any push of PR #263 — every run was superseded in the queue before it left pending, so the PR never showed the failure. The job needs neither CUDA nor a GPU (pure static analysis), but no local gate the row ran covered it either: scripts/agent-preflight.sh does not include it.
Verified as introduced by that row, not pre-existing: origin/main @f323907e (immediately before the landing) reports vt_ifdef=32 -> total 32, ratchet holds.
Fix in flight: move the build-time gate into BuildDenseHeadMarlinResident, inside the #ifdef VT_MARLIN_NVFP4 region that already owns this kernel family, with an #else stub. Predicate and behavior unchanged. The checker's own message forbids both growing the DSR-ALLOW list and raising the baseline, so the gate moves rather than gets excused.
