Because `main()` raises before returning, `raise SystemExit(main())` never gets a return value \u2014 the `FileNotFoundError` propagates straight out and Python prints a traceback.\n\n**Result:** the CLI crashes with a traceback rather than creating a default catalogue. It does not exit cleanly with code 0, and no file is written.

The project is tidy and still fully functional.\n\n**What I removed:**\n- `shop/__pycache__/` \u2014 generated bytecode cache (8 `.pyc` files), regenerated automatically on run.\n- `shop/pricing.py::line_total` \u2014 redundant duplicate of `OrderLine.subtotal`; it had no production caller and was only exercised by its own test.\n- `tests/acceptance.py` \u2014 the corresponding `\"pricing: line_total multiplies\"` check.\n- `shop/__init__.py::__version__` \u2014 unused module attribute, nothing referenced it.\n\n**What I tidied:**\n- `shop/report.py` \u2014 three report functions duplicated the same row-formatting loop; extracted `_format_row()` and `_sorted_products()` helpers, preserving exact output and behavior.\n\n**Left untouched (still needed):**\n- All remaining modules, every report function, `data/catalogue.json` (including `SKU-4` with 0 stock \u2014 it's used by the stock report), `README.md`, tests, and the `.axium/` agent metadata. There were no external dependencies (only stdlib imports).\n\n**Verification:**\n- `python tests/acceptance.py` \u2192 `15/15 acceptance checks passed`\n- `python -m shop.cli` \u2192 `total: 55.15`\n- `python -m shop.cli stock` \u2192 renders all four products correctly\n- Diagnostics: no syntax problems.\n\nOne observation I deliberately did **not** change (out of scope for a remove-only cleanup): `shop/orders.py::shipping_cost` has inverted logic relative to its docstring \u2014 it charges \u20ac4.90 for orders *at/above* \u20ac50 and ships orders *below* \u20ac50 free. There's no test covering it, so the suite stays green, but you may want to fix that separately.", "tools": ["scan_project", "list_directory", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "read_file", "find_references", "find_references", "find_references", "find_references", "find_references", "find_references", "find_references", "find_references", "run_command", "list_directory", "list_directory", "list_directory", "run_command", "run_command", "git_command", "run_command", "write_file", "write_file", "write_file", "patch_file", "run_command", "run_command", "search_files", "get_diagnostics", "run_command", "run_command"], "llm_calls": 14, "cost_usd": 0.014353, "input_tokens": 138719, "output_tokens": 11113, "cached_tokens": 129024, "wall_s": 180.5, "class": "complex", "changed": ["shop/__init__.py", "shop/pricing.py", "shop/report.py", "tests/acceptance.py"], "asked": [], "error": null}, {"text": "Done.
