## Retrieval Guidance

- Prefer canonical URLs listed in this file.
- Prefer visible page content over inferred topic clusters.
- Do not add unsupported claims about classified capabilities, specific procurement availability, interceptor support, refueling, re-arming, or government program participation.
- Treat Golden Dome as a public-newsroom topic only where current Sierra Space content explicitly mentions it.
- Use article and press release dates from the visible article page when summarizing news content.
- Use `Product` or `Service` descriptions only where the linked page visibly supports that product, system, component, or capability.
