+# REOPENED 2026-09-28 same evening: the eugr/spark-vllm-b12x nightly (source
+# local-inference-lab/vllm@dev/karmic-kraken) landed all four missing pieces
+# on 2026-09-22 — MiMo aux-state loading, block-outermost KV layouts for
+# mixed page sizes, b12x non-causal attention (so the DFlash draft runs B12X
+# too), and the eagle3 language-model unwrap. It also ships cached
+# serve-launchers (serve-mimo26-flash.sh) that define the canonical MiMo
+# flag set; we mirror them. No local image build: docker_image is the
+# nightly tag, distributed to nodes by save/load.
