  "limitations": [
    "Covariance propagation is exercised with C = diag(stat^2) + outer(sys,sys), following a declared IAEA-style approximation. It is an assumption-derived lower bound, not a source-released covariance; unknown partial correlations and model-form error remain unavailable, not zero.",
    "The kinetic framework evaluates positive isotropic distributions and the full two-species angular integral, but it does not solve a Fokker-Planck equation or compute the power needed to sustain a non-Maxwellian tail.",
    "Relativistic bremsstrahlung and optically-thin Maxwell-Juettner synchrotron emission are implemented. Net synchrotron loss remains unavailable without absorption, geometry, reflectivity, spectral transport, and a nonthermal electron-tail model.",
    "The stability module implements and analytically benchmarks the exact linear magnetized Rayleigh-Taylor interface dispersion. It is not a global equilibrium-coupled eigenmode or device-stability solver.",
    "The Grad-Shafranov solver is verified against the Solov'ev analytic equilibrium only; it has not been benchmarked against an independent equilibrium code.",
    "The new scientific-core modules are wired into a browser workbench with stale-result export protection, but the browser view does not add physics beyond the registered kernels.",
    "Four new model records are internally verified but unreviewed. Reference-only and preprint records remain non-default until their coefficients and provenance receive independent review.",
    "Phase 4 independent validation is 0/3. A passing self-run or internal test cannot satisfy third-party reproduction, an external benchmark, or institutional sign-off."
