Superset Determinations in Modal Triplet Theory

We formulate the MTT superset program as a parameter-identifiability framework. Embedded renormalized-Standard-Model equivalence closes at the adopted one-shared-physical-primitive and measured-profile standard using selected SMDR v1.3 transport and a complete eight-row covariance. The construction ledger contains one shared electroweak primitive and 15 measured SM profile coordinates; transported couplings, nine charged Yukawa rows, the Higgs row, covariance entries, and the 96-dimensional finite Dirac operator are outputs and are not counted again as independent inputs. Exact source-side structure includes the native faithful gauge group, anomaly-free chiral carrier, completed finite triple, one-Higgs projector, and 10/10 finite gauge/ghost spectrum rows. None of these presently replaces the measured profile by a zero-primitive source theorem. We classify every result as a structural theorem, calibration, profile/replay, diagnostic, or held-out prediction and state the resulting identifiability limits.
