 Relevant commits: `47c301c`, `ac6e0e0`, and the 2026-07-12 handoff update.
 
+On 2026-07-28 the runtime moved to llama.cpp after repeated Ollama runner churn and
+resource-residency ambiguity. Luna was isolated on the NAS AMD iGPU through Vulkan,
+while Terra and Sol became two API behaviors over one fixed 27B CUDA runner on the
+V100. The web app now uses the servers' OpenAI-compatible endpoints, fixes context
+at deployment time, and controls thinking by tier.

+Decision retained: product tiers do not require separate physical model copies.
+Keep resource ownership in the serving layer and let Terra/Sol share one resident
+runner when their weights are identical.
