Research direction

Read astrbot/core/utils/t2i/renderer.py, starting at the remote-renderer fallback and the call to LocalRenderStrategy.render(text). Check how return_url=True is handled by the public Star.text_to_image entry point and local strategy; done means callers receive a URL or a clear error when a local URL cannot be provided.

Written by the indexing model from the issue text.

Description

The public Star.text_to_image(..., return_url=True) contract says the result is a URL. When the remote renderer fails, astrbot/core/utils/t2i/renderer.py falls back to LocalRenderStrategy.render(text) without forwarding return_url; the local strategy returns a filesystem path. Callers explicitly requesting a URL can therefore receive a local path that cannot be used as a remotely accessible image URL.

Please preserve the requested result kind through fallback, or return a clear error when a local URL cannot be provided.
