Public API demonstration only: U=1e-3 equilibrium periodic shear, 16x16 coarse, fixed [4,12)^2 2:1 patch, tau .8/1.1, 8 coarse/16 fine steps. Existing equilibrium and macro helpers; correct cell-center/halo-offset sampling; leaf area weights 1/.25. No test oracle, plots, dumps, physical accuracy acceptance or production solver modifications.
Removed obsolete RSS256 assertions and test-only precompilation shim; GPU tests now use the real production constructor/compiler/load path. Tests were syntax checked, not rerun. Example executed ONCE, exit0, through that same production path.
New user resource policy applied: available RAM/VRAM headroom, combined rebuildable temporary files <=2GB; no fixed RSS cap. before.json records immediate physical GPU/RAM checks. results.json records command, settings, resources and source hash; stdout.txt is actual unedited output. Sampling is not an OS hard resource limit. Only own temporary directories removed.
Read-only independent review found no example coordinate, phase or leaf-mass blocker. All historical validation records and existing production files preserved; no environment/system/dependency/DynamisLab changes, commit or push.
