Rotates 5 Oct 2026
Speed Under Budget
Route efficiency 40 or higher while exotic cost stays at 100.
Deep Margin
Robustness 80 or higher — a shell that survives perturbation, not one at the threshold.
Positive Week
Publish a configuration with no exotic energy anywhere (exotic cost 100).
Nothing Exotic
A configuration whose energy density is positive everywhere (exotic cost = 100).
Tier 2 · ~15 min
Comfortably Positive
Positive everywhere AND with real margin — robustness 20 or higher.
Tier 2 · ~15 min
Fast and Positive
Keep the budget positive at real speed: exotic cost 100 with route efficiency ≥ 45.
Tier 3 · ~40 min
The Other Side of c
Cross the light barrier and see the budget break — subluminal safety below 100 with exotic cost below 100. The lesson is the point; the total will not thank you.
