No change shipped. The Steward stays on gemma4:e2b with thinking left at its default, and this records why so the experiment is not repeated on the premise that started it. That premise was wrong. The Steward appeared to pay ~300 tokens per turn for reasoning that was generated and discarded, since no `thinking` field comes back. The reasoning is emitted inline in the response instead, and it is what produces a correct DELEGATE line — suppressing it costs 12.5 points of routing accuracy, entirely on multi-capability queries where the model stops decomposing and names one capability. e4b is disqualified by memory rather than quality: Ollama predicts 10.6 GiB for it against ~7.9 GiB available, so it evicts every co-resident before loading, including nomic-embed-text. Lowering context length does not rescue it — an 8x reduction moved the prediction only 1.1 GiB — and per-request num_ctx reloads the shared runner, dropping the keep_alive pin and evicting nomic. Also records that the two axes are independent: model choice governs VRAM and co-residency, think setting governs tokens and latency and costs nothing in VRAM.
