See what moves
the boundary.
Trace each method from its estimates to the endpoint, and see exactly what it changed.
An endpoint is the result. The proof has dimensions.
Which part of the proof changed?
Pick two methods. Click any cell for its evidence.
Follow the estimates to the endpoint.
Choose a node to trace its inputs and consumers.
Arrows mean “used by”. Every branch remains required.
Comparing moment-capacity regions.
Standard marked moment vs Cycle61’s local affine moment (n₁ = n₂ = m). Length constraints only.
Tap the plot to move the test point.
Dashed box: Cycle61’s local window (0.41 ≤ m ≤ 0.44, 0.034 ≤ z ≤ 0.04); the orange line outside it is extrapolated.
Test a length pair.
Cycle61’s local window: 0.41–0.44.
Move past a boundary to see which gate fails.
Formulas, assumptions, and sources
The standard gate assumes β* ≥ 0.51, 2β* − 1 ≤ κ, and the documented source and slot restrictions. The affine example fixes source width M = 1 and moving width 0, and requires the local m and z box. Values are compared before display rounding. Passing these length gates alone does not certify a new endpoint.
Use the right chart for the question.
Matrix: where a method intervenes. Proof map: how it reaches the endpoint. Capacity: estimates in real units. Spider-plot area is not strength.
