## Data quality

- WUSA9 article page was inaccessible (access denied) during retrieval; its headline/snippet appears in search results but full text could not be extracted for verification.
- Local reporting (NBC4) documents a county-level approval and resident objections for a Chantilly data-center project adjacent to the Meadows of Chantilly mobile-home park, but the articles consulted do not explicitly identify the asset by OpenStreetMap way ID or the exact street address '4100 Westfax Drive'.
- Commercial directory/listing pages identify an 'Amazon IAD-9' or 'Westfax' campus at 4100 Westfax Drive, Chantilly, but these directories are not primary permit or hearing records and do not supply details of hearings, benefits, or litigation.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
