#05-T8. Seeds a maximally-populated instance of every transported entity type,
exports via the real IBundleExporter, imports into a fresh target via the real
IBundleImporter (LoadAsync→ApplyAsync, Add path; site/instance types via a
BundleNameMap CreateNew), reloads, and compares by reflection — every public
writable scalar/string property must survive, except an explicit per-type
exclusion list (surrogate Id, remapped FK ids, inheritance-placeholder flags,
and the documented Instance.State→NotDeployed design reset).
23 entity types across 10 [Fact]s. 7 green. 3 red — each surfaces a genuine
residual fidelity hole whose serializer-level unit test is GREEN, proving the
loss is in the full pipeline (exactly the gap class this integration guard
exists to catch), reported for a separate production fix rather than masked:
- ExternalSystemDefinition.MaxRetries / RetryDelay dropped on import Add
- ExternalSystemMethod rows dropped on import Add (only Overwrite syncs them)
- NotificationRecipient rows dropped on export (FindAsync, no Include)
- TemplateFolder.ParentFolderId hierarchy flattened on import Add
