The importer reads pins' Text, Owner and Connections; outgoing connections' Target and TargetPin and incoming connections' Source and SourcePin as hex-id strings; Settings' localisation, text formatter, script support, export version and two content hashes; and Project's Name, DetailName, Guid and TechnicalName, via JSON_TRY_* macros that leave defaults when a key is absent. As the producer noted, UArticyIncomingConnection::GetSourcePin has an inverted null test: with a database it always returns null, and without one it dereferences a null pointer.

Curator qualifications: Code and help read 2026-10-22; importer not built or run; no export file parsed. Defect is a code reading, not observed at runtime.

Limitations: Code and help read 2026-10-22; importer not built or run; no export file parsed.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
