Green Line district · Metamaterials and engineering carriers
Green marks geometry-to-device translation, wave propagation, finite material models, and fabrication-facing research. Simulation, constitutive physics, and experimental evidence remain separately labeled. Transfer through the Subway Python Transit Map.

Phonon plate status
The Phonon Information Carrier plate is preserved in Computational Visual Validation Atlas — Plate Audit II. Its diagonal $47\oplus78$ model verifies an abstract projector harness; it is not yet the canonical Casimir operator, a physical phonon Hamiltonian, or a fabricated metamaterial result.

Molecular-physics bridge
The site’s quantum molecular reference is now Hydrogen Bromide — Ground-State Quantum Molecular Physics, Halide Comparisons, and Entropy Boundaries, organized beneath Quantum Information Theory. It clarifies where molecular Hamiltonians, vibrational cavities, open-system QuTiP models, and material-device claims share methods without becoming the same physical system.

Canonical research boundary
This page consolidates the Google Drive metamaterials corpus into a single engineering map. It separates established constitutive physics, exact finite-dimensional linear algebra, executable Python and QuTiP models, proposed device architectures, fabrication targets, and speculative KKP bridges.
A metamaterial is an engineered medium whose effective response is produced primarily by geometry, topology, resonant substructure, and boundary conditions. The exact $E_{47}$ projector may be studied as a controller, feature selector, or invariant monitor. It is not, by itself, a permittivity tensor, permeability tensor, elastic modulus, acoustic density, thermal emissivity, band gap, or fabricated material.

The Drive corpus contains a broad, technically recognizable metamaterials program spanning:
The most defensible engineering compression is
$$ \boxed{ \text{geometry} \rightarrow \text{constitutive operator} \rightarrow \text{spectrum} \rightarrow \text{scattering or transport} \rightarrow \text{control} \rightarrow \text{fabrication} \rightarrow \text{measurement} } $$
The corpus is strongest where it uses conventional wave equations, constitutive tensors, graph or finite-element eigenproblems, acoustic impedance, cavity modes, graphene electron–phonon coupling, and explicit numerical residuals. It is conditional where $47/125$, informational curvature, universal coherence, observer effects, inertial modification, or vacuum coupling are assigned direct material meaning without a calibrated constitutive map and bench data.
