🤖 [BEEP BOOP, A BOT WROTE THIS PR - Mistral Large 4, opencode] Fixes the Sphinx warning emitted on every docs build on main: ``` docs/explanation/documentation.rst: WARNING: inventory for external cross-reference not found: 'starflow' intersphinx inventory 'https://canonical-starflow.readthedocs-hosted.com/objects.inv' not fetchable due to <requests.exceptions.HTTPError>: 404 Client Error: Not Found for url: https://documentation.ubuntu.com/starflow/objects.inv ``` The `starflow` intersphinx mapping in `docs/conf.py` points at the retired `canonical-starflow.readthedocs-hosted.com`, which redirects to a 404. The `:external+starflow:ref:`how-to-starcraft-style-guide`` role in `docs/explanation/documentation.rst` therefore cannot resolve. Fix: point the mapping at the live inventory, `https://documentation.ubuntu.com/starflow/latest` (which contains the `how-to-starcraft-style-guide` label). This is the same URL starbase already uses, so it also drops out of the update-starbase merge PR (#203) once this lands. Verified (worktree on `origin/main`, CI-equivalent setup — uv venv with the docs group, then `make docs`): - `make docs` succeeds (`sphinx-build --fail-on-warning`): zero intersphinx warnings (was: inventory not fetchable + cross-reference not found) - The built `docs/_build/explanation/documentation/index.html` links to `https://documentation.ubuntu.com/starflow/latest/how-to/starcraft-style-guide/` Note: this PR is opened from the `LoweRAM/debcraft` fork because the LoweRAM account has read-only access to `canonical/debcraft` (fork PRs are the standard flow for that).
