Figures of merit

The tier is each figure's validation status, read from the engine's own figure_tiers block: validated means checked against an independent external oracle; modelled means first-principles physics with tests, not yet oracle-checked.

Every published figure

Read from the result document with the unit, note and provenance the engine records for each one.

Filter health Kalman self-consistency

A consistent filter's reported uncertainty matches its actual errors. NIS (normalised innovation squared) should sit near 1 and NEES (normalised estimation error squared) near 2, each inside its 95% χ² band.

Mask checks and holdover budgets

Each check's limit is plotted as a ring at the averaging time where the margin was worst. Masks are transcribed from the ITU-T (International Telecommunication Union Telecommunication Standardization Sector) Recommendations named in each row.

Parameter sweep

Run the engine once per value and plot one figure of merit. Add a second parameter for a heat map. Every point is a real engine run, up to 60.

Key figures, run against run

The headline readouts of each pinned run; the change is against run A.
