| ------------------------ | ------------------------------ |
| `index.json`             | Version and collection counts  |
| `catalog.json`           | Flattened multi-object catalog |
| `graph.json`             | Nodes and semantic edges       |

## Future API mapping

```text theme={null}
GET /v1/knowledge
GET /v1/catalog
GET /v1/topics/:id
GET /v1/glossary/:id
GET /v1/graph
GET /v1/books/:id
GET /v1/research/:id
```

These are planned mappings, not currently declared production endpoints.
