IDENTITY BASIS
Why these records belong together.
Loudoun LandMARC issued-permit rows share parcel PIN 088101859000. Address variants remain visible and are not treated as proof of a single operator or campus owner.
Operator named in sources: Not normalized from the current record.
Identity linkage is not an ownership conclusion. Applicant, operator, developer, landowner and permittee can be different entities.
EVIDENCE LAYERS
One row per government record.
Each value carries its own stage and source basis. Requested values never become permitted or operational through aggregation.
