+## Batch T final campaign-label naming cleanup
+
+A final class/method-name sweep found one campaign-labelled class and two
+isolated slice-labelled methods whose names hid otherwise durable behavior.
+Batch T makes naming-only changes:
+
+- `OP2ReworkBlastRadiusConformanceTests` becomes
+  `DormantDatWidgetConformanceTests`. Its eight contracts protect dormant
+  Type-5/Type-8 DAT widget behavior, not the OP2 work sequence that discovered
+  the blast radius. Research records retain the OP2 history and now point to
+  the descriptive class name;
+- `G2_VendorStackSelection_ThroughRealMaterializer_ShowsSplitSlider` becomes
+  `VendorStackSelection_ThroughRealMaterializer_ShowsSplitSlider`; and
+- `C4_VendorOwnedSplitExemptStackSelection_MatchesRetailsToolbarPresentation`
+  becomes
+  `VendorOwnedSplitExemptStackSelection_MatchesRetailsToolbarPresentation`.
+
+The detailed G2/C4/AP-169 evidence comments remain beside the two selection
+tests. No assertion, fixture, product code, or historical research statement
+was removed. The broader short-label sweep also found complete scenario
+matrices such as A1-A6/B1-B3/C1-C3/D1-D4; those labels remain because they
+identify deliberate rows within a documented matrix rather than a stale
+campaign identity.
+
+Verification:
+
+- the focused Batch T filter passes all 10 renamed contracts with zero skips
+  or failures;
+- the complete 44-project Release build reports zero warnings and zero errors;
+  and
+- the no-retry complete hermetic Release gate passes 14,379/14,379 with zero
+  skips or failures across all 12 test assemblies.
