Produces one row per product.\n\nIt does not calculate totals, exclude zero-stock items, or display SKUs.\n\n### `low_stock_report`\n\n`low_stock_report(inventory, threshold=5)` uses the same formatting and sorting, but includes only products where:\n\n`p.stock <= threshold`\n\nWith the default threshold of `5`, products with stock of 5 or less appear. That includes zero stock, and would also include negative stock if it occurred. Products above 5 are omitted.\n\n## Stock report\n\n| Widget                   |     40 |\n| Gadget                   |     12 |\n| Doohickey                |      3 |\n| Thingamajig              |      0 |\n\n## Low-stock report\n\nUsing the default threshold of 5:\n\n| Doohickey                |      3 |\n| Thingamajig              |      0 |\n\n## Products in both reports\n\n- **Doohickey**\n- **Thingamajig**", "tools": ["read_file", "read_file", "list_directory", "list_directory", "list_directory", "read_file", "search_files", "read_file", "read_file", "read_file", "read_file", "read_file", "run_command"], "llm_calls": 6, "cost_usd": 0.0, "input_tokens": 19590, "output_tokens": 2202, "cached_tokens": 13376, "wall_s": 27.6, "class": "medium", "changed": [], "asked": [], "error": null}, {"text": "No files were changed.\n\n## `shop/storage.py`\n\nThis module handles reading and writing the product catalogue as JSON.\n\n### `save(path, products)`\n\n```python\ndef save(path, products):\n```\n\nIt performs the following steps:\n\n1. Iterates over the supplied `products`.\n2. Converts each product object into a plain dictionary containing:\n   - `sku`\n   - `name`\n   - `unit_price`\n   - `stock`\n   - `category`\n3. Opens `path` in write mode.\n   - An existing file is truncated and replaced.\n   - The parent directory must already exist; `save` does not create directories.\n4. Writes the dictionaries as indented JSON.\n5. Uses `ensure_ascii=False`, so non-ASCII characters can be written directly rather than escaped.\n6. Returns the number of products written.\n\nFor example, saving three products returns `3`.\n\nIt does not catch errors. Problems such as an invalid path, missing parent directory, or a product missing one of the expected attributes propagate as exceptions.\n\n### `load(path)`\n\n```python\ndef load(path):\n```\n\nIt:\n\n1. Opens `path` using UTF-8 encoding.\n2. Parses the file contents with `json.load`.\n3. Treats the parsed value as an iterable of product dictionaries.\n4. Reconstructs a `Product` object for each dictionary using `Product(**row)`.\n5. Returns a list of `Product` instances.\n\nIt likewise has no error handling. A missing file, invalid JSON, or dictionary with missing/unexpected fields causes an exception to propagate.\n\n---\n\n## `shop/cli.py`\n\nThis is the command-line entry point.\n\n### Module imports\n\nIt imports:\n\n- `sys`, for reading command-line arguments.\n- `orders`, `report`, and `storage`.\n- `Inventory`.\n- `Order` and `OrderLine`.\n\nImporting the module alone does not load the catalogue. Loading only happens when `main()` is called.\n\n### `build_demo_order(inv)`\n\n```python\ndef build_demo_order(inv):\n```\n\nThis creates a fixed demonstration order:\n\n- Order ID: `D-1`\n- Customer: `demo`\n- Country: `GR`\n- SKU-1 quantity: `2`\n- SKU-2 quantity: `1`\n\nThe prices are looked up from the inventory:\n\n```python\ninv.get(\"SKU-1\").unit_price\ninv.get(\"SKU-2\").unit_price\n```\n\nTherefore, the catalogue must contain both SKUs. If either is absent, `inv.get(...)` returns `None`, and accessing `.unit_price` raises `AttributeError`.\n\n### `main(argv=None)`\n\n```python\ndef main(argv=None):\n```\n\nThe control flow is:\n\n1. It chooses the arguments:\n   - If `argv` is truthy, it uses that value.\n   - Otherwise, it uses `sys.argv[1:]`.\n2. It loads `data/catalogue.json`.\n3. It wraps the resulting products in an `Inventory`.\n4. If the first argument is exactly `\"stock\"`:\n   - It generates `report.stock_report(inv)`.\n   - Prints the report.\n   - Returns `0`.\n5. For any other argument\u2014or no argument\u2014it:\n   - Builds the fixed demo order.\n   - Calculates its total with `orders.order_total(order)`.\n   - Prints it as `total: NN.NN`.\n   - Returns `0`.\n\nOnly the first argument matters. For example, `stock extra` still selects the stock report, while any first argument other than `stock` selects the demo-total path.\n\nOne subtlety is that `argv=[]` is treated as false, so it falls back to the process\u2019s actual command-line arguments rather than explicitly meaning \u201cno arguments.\u201d\n\n### Module entry-point guard\n\n```python\nif __name__ == \"__main__\":\n    raise SystemExit(main())\n```\n\nWhen run with:\n\n```text\npython -m shop.cli\n```\n\nPython calls `main()` and turns its return value into the process exit status.\n\n---\n\n## What happens on a fresh install with no catalogue file?\n\nBoth commands attempt to load the catalogue before deciding which operation to perform:\n\n```python\ninv = Inventory(storage.load(\"data/catalogue.json\"))\n```\n\nConsequently, these commands both fail if the file is absent:\n\n```text\npython -m shop.cli\npython -m shop.cli stock\n```\n\n`storage.load` calls `open(\"data/catalogue.json\", encoding=\"utf-8\")`. If the file does not exist, Python raises an uncaught `FileNotFoundError`, typically showing a traceback ending with an error similar to:\n\n```text\nFileNotFoundError: [Errno 2", "tools": ["read_file", "read_file"], "llm_calls": 3, "cost_usd": 0.0, "input_tokens": 13854, "output_tokens": 2205, "cached_tokens": 12493, "wall_s": 22.1, "class": "medium", "changed": [], "asked": [], "error": null}, {"text": "No files were changed.\n\n## Module summaries\n\n- **`shop/__init__.py`** \u2014 Defines the package metadata and exposes version `0.3.0`.\n- **`shop/models.py`** \u2014 Defines the `Product`, `OrderLine`, and `Order` dataclasses, including line subtotals and order item counts.\n- **`shop/pricing.py`** \u2014 Implements line totals, bulk discounts for quantities above 10, and country-based VAT calculation.\n- **`shop/inventory.py`** \u2014 Maintains products by SKU and supports lookup, availability checks, reservations, and restocking.\n- **`shop/orders.py`** \u2014 Calculates order subtotals and final totals by combining product totals, pricing adjustments, tax, and shipping.\n- **`shop/report.py`** \u2014 Generates product-ranking, stock, category, and low-stock text reports.\n- **`shop/storage.py`** \u2014 Serializes product objects to JSON and reconstructs them from catalogue JSON files.\n- **`shop/cli.py`** \u2014 Loads the catalogue and either prints the stock report or calculates the built-in demonstration order total.\n- **`tests/acceptance.py`** \u2014 Runs the project\u2019s custom regression checks covering models, pricing, inventory, orders, reports, storage, and CLI behavior.\n\nThe `README.md` and `data/catalogue.json` are documentation and data files, not Python modules.\n\n## Most tightly coupled pair\n\n**`shop/orders.py` and `shop/pricing.py`** are the most tightly coupled by direct module dependency: `orders.py` imports `pricing` and calls its discount and tax functions when calculating an order total.\n\nA close secondary coupling is **`shop/storage.py` and `shop.models.py`**: storage hard-codes the `Product` fields when saving and uses `Product(**row)` when loading.\n\nOne current behavior worth noting: `orders.py` presently makes orders below \u20ac50 ship free and charges \u20ac4.90 at or above \u20ac50, which conflicts with its own docstring and the standing \u20ac75 free-shipping rule.
