## Data quality

- The official Texas Department of Licensing and Regulation filing identifies Project TABS2026014987 as BITTER BLUE, Building B, at 12807 Donop Road, San Antonio, Bexar County. It lists Amazon Data Services Inc. as owner and describes a privately funded, two-story, single-tenant computer data center.
- The reviewed exact-site coverage concerns project identification, cost, size, ownership, and schedule; it does not report a site-specific community-benefit agreement, jobs commitment, public hearing, petition, organized community group, opposition campaign, or litigation.
- Older reporting about Bitterblue mixed-use development and other San Antonio data-center projects was excluded when it did not identify 12807 Donop Road or the Bitter Blue data-center filing. No MW, water-use, PUE, WUE, tenant, or commercial-term claims are made here.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
