Every number in the burner's reference phase is a deterministic solve on a fixed grid. A random seed is set purely for hygiene; no randomness enters the physics anywhere. Rerun the scan — 51,840 points, zero failures — and the answer is identical.
The reference phase evaluates a fixed design-space grid with no Monte Carlo, no stochastic solver, no random sampling in the physics. A seed is set only for reproducibility hygiene. The scan covers 51,840 design points and 84 window points with zero failures, and every point is a deterministic function of its inputs.
Determinism is what makes 'reproduce from source' literally true: there is no run-to-run variation to explain away. An outside reviewer who reruns the deposit lands on the exact same design point, which is the strongest possible form of an auditable result.
