Validated example atlas#
These are all 47 passing cases in the current catalog. Each page explains the physical claim, shows the exact recorded metric, identifies its source files, and gives the one-command reproduction path. The gallery is generated from benchmarks/cases/*/case.yaml and progress.json so it cannot silently drift from the suite. Failed inverse-design fidelity audits remain visible on the separate real-world audit page, but are not counted here.
How to read this gallery
“Analytical” means an independent formula or invariant. “Forward” means comparison against a frozen Tidy3D golden. “Invdes” means objective-performance parity. Passing does not imply that every Tidy3D feature is implemented; see validation status for the boundary.
