The DiffusionGemma arch is NATIVE in v0.24.0 (PR #45163 merged 2026-06-12), so
the vllm-diffusion-gemma engine drops the mutable/branch :gemma digest for the
same pinned stable tag the rest of the stack uses. The 3 Ampere/TP fix-mounts
STAY (not in #45163): marlin.py + marlin_utils_fp8.py (sm_86 fp8 MoE Marlin
K-pad — #45295's dense marlin-pad in v0.24.0 does NOT cover marlin_moe_wna16)
and diffusion_gemma.py (TP-vocab; native #45163 copy is still TP=1).
Also fixes the compose for v0.24.0's arg-parser: the bare positional model must
be the --model flag (the entrypoint prepends --disable-custom-all-reduce).
Live-validated 2026-07-02: the actual compose boots + serves coherent at TP=2 on
stock v0.24.0 (Paris / primary colors / 42). Suite 59 pass / 1 pre-existing
(test-submit-bench worktree-fixture-absent).
- engine vllm-diffusion-gemma.yml: install.spec :gemma@digest -> v0.24.0 + provenance
- compose base.yml: image default -> v0.24.0 + --model flag fix + header
- patches.yml dgemma-gemma-image-fixes: reason/drift_guard/drop_when -> v0.24.0
- BENCHMARKS + UPSTREAM #45163 row: reflect the bump
