## Before you build anything

Always inventory. Never hallucinate view types, widget kinds, or profiles.

```
GET /api/hub/manifest
  → static capability map: view types, bento block kinds, inline patterns, browser-native cells
    (call once per session — no DB queries, safe to cache)

GET /api/hub/profiles?userId={userId}&workspaceId={workspaceId}
  → what data exists

GET /api/hub/widget-definitions?workspaceId={workspaceId}
  → [{ kind, category, label, description, configSchema, supportedContexts }]

GET /api/hub/views?userId={userId}&workspaceId={workspaceId}
  → [{ id, name, type, profileSlug, config }]
```

Widget definitions are the source of truth for which cells are installed and how to configure them. **Never guess cell kinds.** If a cell doesn't appear in the registry, don't reference it (unless it's a browser-native cell from the manifest).
