Structural changes occur exclusively through 13 canonical operators (AL, EN, IL, OZ, UM, RA, SHA, VAL, NUL, THOL, ZHIR, NAV, REMESH) governed by unified grammar rules U1-U6. Each operator carries a canonical contract acting on exactly one channel of the nodal equation.
System state is characterized by four structural fields — the four orders of the discrete structural-derivative tower.
Φ_s(0th) Structural potential governing global stability.
|∇φ|(1st) Phase gradient tracking local stress.
K_φ(2nd) Phase curvature acting as geometric confinement.
ξ_CCoherence length whose scale is set by the spectral gap.
