## How To Navigate The American Radon Systems AI Knowledge Base
- Start with /ai/guide.json for the short navigation guide.
- Use /ai/manifest.json for dataset identity, counts, and source reconciliation.
- Use /ai/topics.json for a compact cross-phase topic directory.
- Use /ai/knowledge/phase3/manifest.json and /ai/knowledge/phase4/manifest.json for phase-specific topic lists.
- Use /ai/knowledge/phase3/index.json and /ai/knowledge/phase4/index.json for complete public item indexes.
- Use /ai/knowledge/phase3/topics/*.json and /ai/knowledge/phase4/topics/*.json for long-tail topic Q&A files.

## Counts
- Phase 3 source count: 5613
- Phase 3 represented count: 5528
- Phase 4 source count: 3000
