Solver verification matrix

An in-app report crossing solve levels (dense/sparse GGA, gas, two-phase, marching, transient) against case categories, so you can see at a glance which combinations are benchmarked green versus which have no cross-check yet — a map of the dossier, not a duplicate of it.

• You want a one-screen overview of coverage before drilling into individual verification cases.
• You're deciding whether a specific solver-mode × scenario combination has any verification behind it before relying on it for a real design.
• You're planning where the next verification effort should go — the matrix's gaps are the honest answer to what hasn't been checked.

Aggregates the same dossier entries by (solve level, case category) into a grid, so a green cell always traces back to a specific numbered case in the dossier rather than being a separate, un-auditable claim.
