+Wide-x projected three-level shear: exact be8e6d691d6d18baa8403f2d942b5aa382456ac1; production a135252ae78b47b57d7e77d19001700b3bedac8b unchanged.
+72 host tests and one exact dry run pass; one fresh GPU case, no controls or matrix assessor.
+Runner screen pass: False; mechanism usable: True.
+Five main rows, 258 root trace times, unchanged 24 targets and three independently verified pre-cleanup build sidecars.
+Twenty probe locations match original nested, four horizontal probes shift; changed locations excluded from direct comparisons.
+None crosses the new x=28 face. No qualification pass, reflection proof or pure gap-effect claim. Fine substeps unresolved.
+No algorithm changes, reruns, snapshots, field dumps or checkpoints.
