TimeoutSeconds is the per-system HTTP timeout ExternalSystemClient reads at
call time and is deployed to sites (proto field 6), but Transport bundles
silently dropped it: the DTO never carried it, export never wrote it, the
importer's Add path reset it to 0, the Overwrite path left the target's
stale value untouched, and ArtifactDiff never compared it (so a bundle
whose only change was a tuned timeout previewed as Identical).
Adds TimeoutSeconds as an additive-optional trailing field on
ExternalSystemDto (schemaVersion stays 1.1, bundleFormatVersion unchanged)
and threads it through EntitySerializer (export + import), BundleImporter
(Add and Overwrite), and ArtifactDiff.CompareExternalSystem. Old-bundle
semantics pinned: an absent field (null) falls back to the entity default
on Add and leaves the target's existing value untouched on Overwrite/diff.
Beefed up the RoundTripEquivalenceTests external-system fixture with a
non-default TimeoutSeconds so the reflection round-trip guard actually
exercises the field instead of comparing default against default.
Swept the rest of the ExternalSystemDto shape against
ExternalSystemDefinition field-by-field; no other operative field is
missing.
#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
