## Data quality

- The exact asset is the Texas Cryptologic Center/NSA Texas facility at 1 Sony Place; the adjacent Amazon Web Services facility and other nearby Westover Hills projects were not merged into this record.
- The reported community benefits are qualitative and come from official NSA statements and local technology-sector reporting; no unsupported tax, payroll, utility, MW, water-use, PUE, WUE, tenant, equipment, or commercial-term claims are included.
- A third-party result claiming a 40 MW demand was excluded because the available evidence did not establish that figure through an authoritative, site-specific source.
- The DoD Inspector General separately identifies a Texas Cryptologic Center construction project, but the available report page does not provide additional community-impact findings.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
