Indexes the arch-wiki-docs dump that is already on disk and exposes it
to the knowledge-rag MCP server, so Arch questions can be asked by
symptom ("why doesn't my systemd user unit see DISPLAY under i3")
rather than by page title, with no network round-trip at query time.
The one Arch-specific MCP server in the wild fetches pages over the
network and bundles pacman operations that duplicate the local yay-mcp.
This does neither: it only searches, against a local corpus.
install.sh installs its own dependencies, wires the MCP config and
registers a pacman hook so the index follows package updates. The
generated index is machine-specific and regenerable, so it is
gitignored rather than committed.
_reindex_entry runs under the knowledge-rag interpreter, where
mcp_server is importable and this repo's packages are not. Resolving
that import with importlib.import_module states the deferral outright
instead of a function-level import statement that reads as an oversight,
and the backend failure path now re-raises as SystemExit, so the
exit-code translation is explicit rather than a swallowed exception.
Both replace lint suppressions; the package carries none.
pylint runs in its own venv, so beautifulsoup4 and markdownify are
declared there too — being in meta/requirements.txt does not make them
resolvable to the hook.
