# Get Companion App Detail

`GET /api/dock/companion-apps/{application_id}`

Return the pruned detail for one FGA-only companion application.

Only the FGA facets apply (modules + role bundles); application access is
served by the shared ``/scopes/application/{applicationId}/principals``
route. Host coordinates link the companion back to its owner's dock page.

## Path parameters

- `application_id` string, required

## Response `200`

Successful Response

- CompanionAppDetail — Pruned detail view for an FGA-only companion application. A companion has no deployment metadata (no environment, domains, routing, or runtime service account), so only the FGA-relevant facets apply: authorization modules, role bundles, and application access (served separately via the scope-principals endpoint). ``host_app_name`` / ``host_environment`` link back to the owning host's dock detail page.
