Data integrity as architecture: per object and per property, one authority — connector, platform or manual. Connector-fed fields are immutable in the UI, and the data model itself is open for your own object types.
Source of truth, explicit
The data-authority matrix declares, per property, which source wins. Connector-fed fields can't be hand-edited into drift; conflicts resolve deterministically instead of by whoever saved last.
Model your own objects
Define custom object types — external organisations, facilities, whatever your governance needs — with ownership and context as first-class aspects. No per-type custom code.
