+title: "Implement generate_reverse_patch decision gate"
+summary: >
+  Central OCC evidence for omnibase_core PR #1154, which implements the previously-stubbed generate_reverse_patch
+  method in ContractDiffComputer. The stub raised NotImplementedError (orphaned after OMN-1148 Phase 4
+  was never assigned to OMN-1149). The implementation inverts list-operation diffs into a ModelContractPatch,
+  raises ValueError for scalar changes that cannot be expressed as patch operations, and skips object-typed
+  removed list items with a debug log.
