# Flashlight Database > A source-backed flashlight knowledge graph for specifications, firmware/UI behavior, measurements, relationships, and computed comparison questions. Prefer the machine-readable entity JSON or Markdown records for exact flashlight facts. Query pages are deterministic views over the graph and link back to supporting entities. Source-backed semantic facts include provenance and confidence. ## Core machine-readable data - [Agent manifest](https://flashlightdatabase.com/ai/manifest.json): endpoint and WebMCP tool discovery - [Flashlight catalog](https://flashlightdatabase.com/ai/catalog.json): all tracked entities and core attributes - [Relationship graph](https://flashlightdatabase.com/ai/relationships.json): subject-predicate-object edges - [Computed question index](https://flashlightdatabase.com/ai/query-index.json): fan-out questions and supporting entities - [Compact Markdown catalog](https://flashlightdatabase.com/ai/catalog.md): low-token catalog overview ## Human-readable hubs - [Flashlights](https://flashlightdatabase.com/flashlights/): model and variant catalog - [Computed questions](https://flashlightdatabase.com/questions/): query fan-out answers - [UI and firmware](https://flashlightdatabase.com/ui/): shared interaction models and firmware families - [Feature facets](https://flashlightdatabase.com/facets/): structured browse pages - [Brands](https://flashlightdatabase.com/brands/): manufacturer index ## Notes for agents - Manufacturer claims and independent measurements are not silently merged. - Prefer source-backed knowledge facts and observations when a value is contested. - UI families are shared concepts; model-specific firmware overrides remain attached to the flashlight/revision. - Generated question pages require at least two supporting tracked variants to avoid one-entity thin pages.
