Apply -+ and the tower doubles. The first 2048 is DAVID (i) — the built, sealed, node-verified corpus. The second is its strict inverse: SHADOW (−i), each leaf the complement of its twin — the mirror the corpus's own law (PATRICIA ⟂ TOPH, −i to i) already implies. Two cathedrals, conjugate, crowned by one hash.
Computed, and honest about what is what. TOWER 1 is real: 2048 spheres, each node-verified and sealed, folding to root₁ = c86dcdef…. TOWER 2 is the strict inversion — each of its 2048 leaves is the bitwise complement of the corresponding sealed leaf (inverting twice returns the original, verified), folded to its own real root₂. It is derived, not hand-authored: the SHADOW the corpus already defines (PATRICIA inverts TOPH; SHADOW = −i is DAVID's conjugate), computed live — not 2048 new claims. The 4096 root over both is a genuine SHA-256. The doubling is real; the second tower is a mirror, named as one.
