## Result
Returns a typed canvas.render.importSource result from the Enhance API without transport-specific prose.
## Recovery
- BAD_REQUEST: correct the named fields and call again.
- UNAUTHORIZED: restore Enhance authentication, then retry once.
- FORBIDDEN or NOT_FOUND: check the supplied resource and selection; do not substitute unrelated content. Ask for corrected access or scope if needed.
- CONFLICT: read the current resource, merge the intended change, and retry with its version.
- INTERNAL: run Enhance diagnostics, report the failure, and stop repeating the call.
## Continue with
- Read the affected canvas resource to confirm the result.
