What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

- Permanent jobs promised

Which document closes each gap
- Power capacity in megawatts
- The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
