Protected Reconstruction from Codazzi Defects: Equianharmonic Quantization and a Minimal Standard-Model Carrier

Protected least-sufficient reconstruction (PLSR) is applied to a codimension-three timelike Codazzi defect with a primitive projective link and two non-scalar source grades. Exact marked recovery selects E₃ ⊕ E₂ and M₃(C) ⊕ M₂(C). Primitive multiplication unifies the projective exact sequence, the rigid (2, 3) correspondence, its Green metric, the minimal rank-five Hermitian carrier, and a structural dark port line. Centered determinant/Clifford completion gives S(U(3) × U(2)), the primitive Z₆ quotient, chiral 16-plets, and k_Y = 5/3; the integral A₂ branch gives the three-state family orbit and primitive commensurate norm-seven class. One Alena-Codazzi response supplies typed realization tests. Its finite realization combines the upstream source/local incidences with three executable packets: a marked four-moment primitive-port certificate, a control-basis-invariant scalar/trace susceptibility residual, and a common-root holonomy test whose remaining primitive-root lift is one Z₂ bit. After the stated exact reduced attachments, the scale-free response is a one-dimensional saturation manifold with global coordinate u and a discrete norm-seven orientation. One predeclared scale-free observable may locate u; the remaining continuous CKM, PMNS, neutral-shape, and bosonic coordinates are no-retune tests. Absolute normalization, continuum poles and lifetimes, and precision matching remain separate completion problems.
