Filings and reviews: dated data center events

Applications an official body recorded as filed, received or complete, and notices opening an official review. A filing or review is not an approval.

Three different things, kept apart. Facility and project events happened in the world on the date the source gives. Evidence updates are DataCenterData publishing records; they are not events at a facility. Corrections to what DataCenterData published live in the corrections history, the corrections authority.
