Revision history for Physics-Stellarator

0.02  2026-07-06
      - Physics::CPD::Stellarator: theoretical fusion-power production for a
        50:50 D-T plasma - Bosch-Hale reactivity (dt_reactivity), fusion power
        density and total fusion power (fusion_power / fusion_power_MW), the
        neutron/alpha split (neutron_power_MW / alpha_power_MW), neutron wall
        loading (neutron_wall_load), fusion gain Q (fusion_gain_Q) and a
        power_report; new dt_fuel_fraction attribute.
      - examples/power_production.pl: theoretical D-T fusion power of the
        W7-X-class design with ion-temperature and density scans.
      - README: added a full API reference for both modules and a fusion-power
        section; expanded method/attribute documentation in the POD.
      - Tests: t/05-fusion.t validates the reactivity and power relationships.

0.01  2026-07-06
      - Initial release.
      - Physics::CPD: pure-Perl computational-plasma-dynamics engine
        (plasma/cyclotron frequencies, Debye length, gyroradii, thermal and
        Alfven speeds, ion sound speed, pressures, beta, Coulomb logarithm,
        collision frequency, mean free path, Spitzer resistivity, plasma
        parameter; multi-species support).
      - Physics::CPD::Stellarator: Wendelstein 7-X model extending Physics::CPD
        (aspect ratio, plasma volume/surface, rotational transform, ISS04
        confinement scaling, stored energy, Sudo density limit, beta/density
        fractions, Lawson triple product, ECRH resonance field, radial
        profiles).
      - VMEC-style Fourier boundary geometry: flux surfaces, helical magnetic
        axis, nested surfaces and modular coils.
      - Plotting via PDL::Graphics::Gnuplot: 3-D design diagram, poloidal
        cross sections, radial profiles and confinement scans.
