Theta Zero Is an Antidiagonal Seam State, Not Two Dirichlet Tails
For the doubled half-tail system
a completed theta zero imposes
not separate Dirichlet conditions on the two tails. The full state may remain nonzero while its scalar seam aggregation vanishes.
With
the exact Green identity is
The antidiagonal zero condition and tail decay make the flux vanish at both endpoints. The remaining RH-bearing obstruction is therefore the single integrated forcing term.
