Same Weights, Different Engine: XeStrata on the Arc Pro B70, and the Conversation That Survived a Restart

A second engine for the same Qwen3.8 model wins on speed, then learns to keep long conversations on the SSD. Also: the test harness that asked us to load the wrong model.

Approved for the main role. Same weights, tuned XeStrata: decode +6 to +15%, prompt reading +40 to +62%, quality 12/12 like production. Our fork resumes long conversations from SSD after a restart. Its SSD write volume needed one more fix, now being measured.
