Manufacturing riskLowNo pin-map mismatch found
Ordering riskHighMPN and datasheet URL are not exposed in current part metadata
Documentation completenessNeeds workImportant electrical properties are not stored as project properties

Issues to flag

SeverityIssueWhy it matters
HighMissing explicit MPN in accessible part metadataCan cause incorrect or incomplete ordering/BOM linkage
HighMissing explicit Datasheet property in accessible part metadataMakes verification and reuse harder
MediumElectrical properties are not stored as structured part propertiesReduces part quality and reviewability
LowNo symbol-to-footprint mismatch foundGood news: no immediate board-failure risk from pinout/package mapping
If you want, the next action is to set the part’s Datasheet property to the official TI PDF above.
