[0.15.0] — 2026-03-11

Fixed

• GS* stencil sign bug: east/west coefficients in Jacobi, SOR, multigrid, and JAX solvers had the 1/(2R·dR) sign swapped — implementing the cylindrical Laplacian (∂²ψ/∂R² + (1/R)∂ψ/∂R) instead of the correct GS* operator (∂²ψ/∂R² − (1/R)∂ψ/∂R). Python now matches Rust sor.rs. Verified via Solov'ev exact solution (< 1% error on 33×33 grid).
• beta_N formula (TokamakEnv): replaced dimensionally incorrect sqrt(Ip) expression with Troyon scaling β_N = c·T/Ip, calibrated to ITER baseline
• gain_margin_db misnomer: renamed to stability_margin_db (eigenvalue-based, not Bode gain margin); backward-compat alias retained
• MPC docstring: states clearly this is gradient-based trajectory optimization, not Rawlings-Mayne MPC
• Physics citations: Braginskii tau_eq, Martin L-H threshold, Troyon beta_N, Wesson q95 — all hardcoded constants now cite source
• H-infinity Y Riccati tolerance: tightened from 1.0 to 0.01
• IPB98(y,2) RMSE gate: tightened from 200% to 80%

Added

• Solov'ev analytic equilibrium test (GS solver vs exact ψ)
• Crank-Nicolson CN-vs-Euler convergence test and pure diffusion decay test
• validate-rmse CLI command (full RMSE dashboard)

Changed

• 2,420 tests, 0 failures, 105 skipped
• Version bump: v0.14.1 → v0.15.0

[0.14.1] — 2026-03-11

Fixed

• Jacobi step: add 1/R toroidal stencil (was Cartesian Laplacian, affecting fallback solver path)
• Vacuum field: multiply coil current by turns (was ignoring multi-turn coils)
• JAX GS boundary: use ψ_bdry=0.0 Dirichlet BC (was reading corner value)
• UPDE Rust fast-path: return "Psi_global" key (was "Psi", breaking downstream code when Rust backend active)
• Green's function: divide by k² not k in toroidal formula
• Bootstrap current: use minor radius a, not domain extent R_max−R_min
• lyapunov_v docstring: range is [0, 2] not [0, 1]
• Neural transport docstring: honest about MLP architecture (not full QLKNN-10D)

Added

• 13 analytic regression tests (test_p0_regression.py): Jacobi toroidal stencil, vacuum field turns scaling, UPDE key parity, GS boundary conditions, 2-oscillator Kuramoto exponential convergence, sub/supercritical phase transition thresholds
