+- **Preconditions**: The shared package test suite is available.
+- **Steps**:
+  1. Run the shared error helper tests.
+  2. Inspect the live runtime and Edit code list used by the test.
+- **Expected**: Every live code in the error-code specification, including
+  context-compaction, empty-response, and Edit recovery failures, exists in
+  `packages/shared/src/errors.ts` with an identical key and value. Reserved
+  codes remain excluded until they are emitted.
