The current projection contains one award release, not a verified chain of planning, tender, award, contract and modification records. Dates are shown in source-field order and are not silently repaired.
A company profile appears only when this release carries a usable company number. Name-only suppliers remain name-only.
No supplier is named in this projection. That does not prove the notice had no supplier in every source version.
