Release and the three endings

Three endings are available:

1. Constructed. The gauge, the response, and all ${\kappa }^2{\hslash }^0$ trees are named, admitted, and the all-tree observable transforms correctly on the frozen algebra through ${\kappa }^2$.

2. Proved obstructed. The all-tree identity acquires a nonzero defect at ${\kappa }^2$, or a tree kernel leaves the declared algebra.

3. Unresolved. A tree is unnamed or its admission is not proved.

The ending reached is (1). The defect of X-E is shown to be a truncation defect of the one-tree observable in the flat gauge, not a field-content obstruction.

A missing object is recorded as missing, not as a no-go. Nothing in this manuscript depends on a state for the graviton.
