+  # Python (uv) — single workspace root.
+  # Dependabot's native `uv` ecosystem detects workspace members through
+  # python/pyproject.toml's [tool.uv.workspace] section and updates the
+  # root python/uv.lock alongside any member's pyproject.toml in the
+  # same PR. Listing each member as its own directory caused Dependabot
+  # to open per-member PRs that did not refresh the root lockfile,
+  # which then failed `uv sync --locked` in CI.
