Public vs Signed-In Detail
The model shows a full public teaser with real geometry and physics, and reveals deeper internal detail to signed-in users.
A two-tier model
The 3D model ships in two tiers. The public tier is genuinely useful: it carries the true machine geometry, every major selectable component, the frozen physics callouts, and the cutaway and exploded views. Nothing in the public tier is faked or dumbed down. The signed-in tier adds a further layer of internal engineering detail.
What the public tier includes
- Complete exterior and layered cutaway geometry for both machines.
- Selectable major components with role, principal dimensions, and material class.
- Frozen canon physics: field on axis, plasma current, breeding ratio target, plug field.
- Assembly order via the exploded view.
What signing in adds
- Finer subassembly breakdown, for example individual blanket sub-modules and coil turn structure.
- Additional internal dimensions and interface detail used in the engineering models.
- Deeper material and tolerance annotations.
Why the split exists
The split protects genuinely detailed engineering work while keeping the public model honest and complete enough to be trusted. It is not a paywall on the science: the physics basis is public. It is a boundary around fine buildable detail, consistent with the design being an active program whose first construction begins Q2 2027.
No economics in either tier
Neither tier carries any cost, price, or financial figure. The model is an engineering and physics record only. For how the two tiers stay consistent, see The Model as Design Record.
