agent-platform release v4.46.0

qwen3-8-27b-l40s serves NVIDIA’s own Qwen3.8-27B-NVFP4 checkpoint from its signed model image (giantswarm/agent-platform#591): nvidia/Qwen3.8-27B-NVFP4 (20.4 GiB — NVFP4 on the MLPs and the language-model head, FP8 on the attention layers) replaces the Inferact repack’s hf:// source; the preset gains the model-image environment (HOME, HF_HOME and VLLM_CACHE_ROOT under /tmp) and declares 21 + 20 GiB. Parsers, the thinking-off default and the 64k context are unchanged; qwen3-8-27b, the Blackwell recipe, still serves the Inferact repack.

The presets no single card holds: qwen3-5-27b, qwen3-coder-next and qwen3-5-35b-a3b (giantswarm/agent-platform#591): 54 GiB BF16, 80 GiB FP8 and 70 GiB BF16 of weights exceed the 48 GB GPU they would target; the presets above are their model-image successors of the same shape. The shipped set goes from twelve to eleven presets; tests/verify-gpu-pool.py leaves each side’s own presets out of the golden comparison until the golden carries this change.
