## Important Crawling Instructions

- Do not crawl or index URLs containing query parameters in the format `f[0]`, 
  `f[1]`, etc. (URL encoded as `f%5B0%5D`, `f%5B1%5D`). These are faceted 
  search result pages that are not canonical content — they are dynamically 
  filtered views of content that exists at stable, canonical URLs.
- Canonical reports and documents are available at `/reports/[report-type]/[report-title]` 
  and should be crawled instead.
- The faceted search interface at `/reports` with no query parameters is the 
  appropriate entry point for browsing reports — individual facet combinations 
  do not represent unique content.
- Prefer crawling the sitemap at `/sitemap.xml` to discover canonical content 
  rather than following facet links.

## Content Available

- [Reports](/reports): Audit reports, inspection reports, and management 
  advisories — canonical versions at 
  `/reports/[report-type]/[report-title]`, for example
  `/reports/audit-reports/relief-supervisor-utilization`
  Known report types include `audit-reports`, `congressional-testimonies`, `other`, `semiannual-reports-to-congress`, and `white-papers`.
- [Investigations](/investigations): Hotline and investigative information
- [About](/about): Mission, leadership, and organizational information
- [Newsroom](/newsroom): Press releases and media resources

## Content to Ignore

- Any URL matching `?f%5B` — these are faceted search permutations
- Any URL with multiple `f[n]` query parameters — these are filtered search 
  views, not unique documents
- `/search?` URLs — full-text search result pages with no canonical value

## Preferred Content Format

Full report content is available as PDF at each canonical report URL. 
Report metadata including title, date, category, and summary is available 
in the HTML of each canonical report page.
