The reports read `p.stock` directly from those product objects. They do not calculate quantities from orders, prices, or sales.\n\n4. Inventory changes are in-memory mutations:\n   - `reserve(sku, quantity)` subtracts from `p.stock`\n   - `restock(sku, quantity)` adds to `p.stock`\n   - Neither report calls these methods, so the displayed values remain those currently held by the `Inventory` object.\n\n### `stock_report(inventory)`\n\n- Iterates through all products.\n- Sorts them by SKU, producing `SKU-1` through `SKU-4`.\n- Displays the product name, truncated to 24 characters and left-aligned.\n- Displays `p.stock`, right-aligned in a six-character field.\n- It does not display the SKU, price, or category.\n\n### `low_stock_report(inventory, threshold=5)`\n\n- Uses the same ordering and formatting.\n- Includes a product when:\n  ```python\n  p.stock <= threshold\n  ```\n- Therefore, the default threshold of `5` is inclusive: stock of exactly 5 is included.\n- Negative stock would also be included.\n- The current CLI exposes `stock` but has no command for low-stock output; the low-stock function must be called directly.\n\n### Other helpers in `report.py`\n\n- `category_report` includes only products whose category exactly equals the supplied category, but still displays stock numbers directly from `p.stock`.\n- `top_products` operates on a separate `sales` mapping, not `Inventory`. Despite its docstring saying \u201cBest-selling products first,\u201d it currently sorts sales values ascending and therefore returns the lowest values first.\n\n## Stock report\n\n```text\n| Widget                   |     40 |\n| Gadget                   |     12 |\n| Doohickey                |      3 |\n| Thingamajig              |      0 |\n```\n\n## Low-stock report, threshold 5\n\n```text\n| Doohickey                |      3 |\n| Thingamajig              |      0 |\n```\n\n## Products appearing in both\n\n- **Doohickey** \u2014 stock `3`\n- **Thingamajig** \u2014 stock `0`\n\nThe overlap is expected because the low-stock report is a filtered subset of the stock report.", "tools": ["todo_write", "brain_brief", "read_files", "todo_write", "search_files", "search_files", "search_files", "list_files", "read_files", "search_files", "todo_write", "run_powershell", "todo_write", "todo_write"], "llm_calls": 12, "cost_usd": 0.0, "input_tokens": 111683, "output_tokens": 9199, "cached_tokens": 94780, "wall_s": 99.4, "class": "", "changed": [], "asked": [], "error": null}, {"text": "No files were changed.\n\n## `shop/storage.py`\n\n### `save(path, products)`\n\nPersists an iterable of product objects as JSON:\n\n1.
