You asked for a field LLM node.
The agent reads the spec into hard constraints before touching geometry — every later decision traces back to these four numbers.
Constraints resolved.
Thermal headroom, power envelope, and memory bandwidth are solved simultaneously — the cross-domain reasoning most teams don't have an engineer for.
Layout & CAD.
The constraint solver places three thermal zones, routes airflow bottom-to-top, and emits parametric CAD (CadQuery → STEP / STL). Hover a part below to locate it.
Bill of materials — with rationale.
Every line carries the agent's reasoning. This is the difference between a parts list and a defensible design.
Validated.
Thermal simulation and operating-mode envelopes confirm the system holds under burst and sustained load — before a single part is ordered.
