Response shape

{
  "ok": true,
  "q": "customers",
  "total": 42,
  "hits": [{"source": "purview", "id": "0e1a-…", "display_name": "customers", "type": "Table", "owner": "alice@", "detail_path": "/catalog/purview/0e1a-…"}],
  "sources": {
    "purview":        {"ok": true,  "count": 7,  "durationMs": 412},
    "unity-catalog":  {"ok": true,  "count": 19, "durationMs": 1138},
    "onelake":        {"ok": false, "count": 0,  "durationMs": 18, "error": "…", "hint": { /* bicep + role hint */ } }
  }
}

Each source is queried independently. Partial success is preserved — when one back-end is down, the others still contribute and the UI renders a precise MessageBar for the failing one. There is no silent fallback to mocks.

Result row

Every hit row carries:

• source — which back-end contributed the row (badge color encodes it)
• display_name + qualified_name (for UC: full three-part name; Purview: qualifiedName; OneLake: workspace + display)
• type
• owner (best effort across sources)
• workspace_name / domain — the parent container
• classifications (Purview only on phase 1)
• detail_path — deep link to the asset detail page in Loom

UI

/catalog → FederatedSearch component. Toolbar shows per-source chips with live counts. Click a chip to restrict the search to that source only. The MessageBar block below the toolbar shows every NotConfigured hint so the operator sees the exact remediation in-page.
