**[P0] Fix indentation in lc_ask main()** The new branch that handles `--index` vs `--key` is mis-indented. The line starting with `if args.index_path:` is dedented with three spaces relative to the four-space block above, so importing or running `src/langchain/lc_ask.py` now raises `IndentationError: unindent does not match any outer indentation level` before the CLI can even parse arguments. Try `python -m py_compile src/langchain/lc_ask.py` or `python src/langchain/lc_ask.py` to see the failure. The CLI is therefore unusable until the indentation is corrected. Useful? React with 👍 / 👎. _Originally posted by @chatgpt-codex-connector[bot] in https://github.com/pfahlr/rag_writer/pull/207#discussion_r2373926873_
