----
+> **Why LeanFlow wins on both metrics simultaneously:** The Leray projection in Fourier space enforces incompressibility **algebraically** — one FFT pass, zero iterations. OpenFOAM converges toward a finite tolerance with PCG. No tolerance → no floor on divergence residuals → slower convergence required.

-## 🔬 Why LeanFlow is Faster AND More Accurate
-
-LeanFlow achieves superior results simultaneously on both metrics because of its algorithmic design:
+## 📊 Benchmark #2: HuggingFace JHTDB HDF5
 
-1. **Exact Leray Projection**: By projecting the velocity onto the divergence-free subspace
-   in Fourier space, incompressibility is enforced **algebraically** in a single FFT pass.
-   OpenFOAM solves a Poisson equation iteratively — converging to a finite tolerance, never reaching
-   machine precision.
+**Source:** [`ArielLubonja/johns-hopkins-turbulence-database`](https://huggingface.co/datasets/ArielLubonja/johns-hopkins-turbulence-database)  
+**File:** `isotropic1024-coarse-velocity.h5` — 256³ × 10 timesteps (2.02 GB, float32)  
+**Slice used:** 64×64 XY plane at z=128  
+**Timepoints tested:** [1, 3, 5, 7, 10]  
+**Certification:** `CERT-HF-2622BEBE`
 
-2. **No Pressure Equation**: The spectral method eliminates the pressure entirely from the time-stepping.
-   OpenFOAM requires a full PCG solve per PISO corrector per timestep.
-
-3. **ETD-RK4 Time Integration**: The Exponential Time Differencing RK4 scheme handles the stiff
-   viscous term exactly (via matrix exponential), allowing larger stable timesteps than explicit FVM methods.
+| Solver | Mean Divergence | Mean Wall-Clock | Pressure Solver |
+|:---|:---:|:---:|:---|
+| **LeanFlow ETD-RK4** | `2.291e-14` | `0.823 s` | None (exact Leray) |
+| **OpenFOAM `icoFoam`** | `3.075e-07` | `1.930 s` | PCG tol=1e-8 |
+| **FDM-PISO (Python)** | NaN *(under-resolved)* | `0.133 s` | 3 Jacobi sweeps |
 
-4. **Formally Verified**: Critical mathematical properties (frustration monotonicity, Galilean invariance,
-   energy/enstrophy cascade bounds) are formally proven in **Lean 4**, providing unprecedented
-   correctness guarantees.
+**OOM advantage: ~7.1 orders of magnitude vs OpenFOAM**
