 profile must not expose. It does not fetch from repositories directly; callers
 provide the asset, representations, versions, metadata records, and
 relationships they have already authorized or loaded.

+## Browser Binding MVP Slice
+
+The service exposes profile-scoped Browser Binding MVP routes:
+
+- `GET /cmis`
+- `GET /cmis/{access_point_id}/browser`
+- `GET /cmis/{access_point_id}/browser/types`
+- `GET /cmis/{access_point_id}/browser/children`
+- `GET /cmis/{access_point_id}/browser/object/{object_id}`
+- `GET /cmis/{access_point_id}/browser/content/{object_id}`
+- `GET /cmis/{access_point_id}/browser/query`
+- `GET /cmis/{access_point_id}/browser/relationships`
+- `GET /cmis/{access_point_id}/browser/changes`
+
+The MVP supports repository info, type definitions, synthetic root children,
+object reads, content stream descriptors, a constrained document query subset,
+relationship objects, and audit-backed change entries. Unsupported query
+grammar returns structured diagnostics.
+
+Route-level tests are present but skip when the optional FastAPI/httpx service
+dependencies are not installed. Runtime-level Browser Binding tests cover the
+same behavior in the default Python test suite.
