`exp-fluid-webgpu-core` records a deterministic fluid and particle-grid baseline before real WGSL pressure solve kernels and atomics-heavy updates land.
The harness fixes particle count, grid size, workgroup size, pressure iterations, dispatch timing, divergence error, atomics note, and thermal note in one schema-aligned result.
Compute Controls
Probe capability first, then run the deterministic fluid simulation to export compute-stress metrics.
