I've derived both reports by hand from the code logic + the actual catalogue data; same output the scripts would print.\n\n## How the reports get their numbers\n\n**Data flow (all numbers trace back to `data/catalogue.json`):**\n\n1. **`storage.load(\"data/catalogue.json\")`** reads the JSON array and builds one `Product` per row via `Product(**row)` \u2014 so every product's `stock` value comes straight from the `\"stock\"` field in the JSON file. Nothing is computed; stock is just whatever the file says.\n2. **`Inventory.__init__`** indexes them: `self.products = {p.sku: p for p in products}` \u2014 a dict keyed by SKU.\n3. **`cli.main`** loads that inventory and, for the `stock` command, calls `report.stock_report(inv)`; there is no CLI path for the low-stock report (it's only callable as a function).\n4. **`stock_report`** iterates `sorted(inventory.products.items())` \u2014 products sorted **alphabetically by SKU** (the dict key). For each it formats `p.name` truncated to 24 chars and left-justified, and `str(p.stock)` right-justified to 6, wrapped in `| ... |`.\n5. **`low_stock_report(inventory, threshold=5)`** does the same iteration/formatting but `continue`s when `p.stock > threshold`. Note the comparison is strictly `>` \u2014 so stock **exactly at** the threshold is included, and so is 0 (out-of-stock items appear).\n\nOne gotcha worth flagging: stock numbers are never recomputed from orders. `Inventory.reserve`/`restock` mutate `Product.stock` at runtime, but nothing in this codebase persists those mutations (the `stock` field in the JSON never changes), and `storage.save` is never called from the CLI.

Returns the number of products written. Note it **overwrites** whatever was at `path` \u2014 no merge, no backup.\n- **`load(path)`**: opens the file (UTF-8), `json.load`s it, and builds a list of `Product(**row)` dataclasses. It assumes the JSON is already an array of flat dicts with exactly the five keys \u2014 no validation, no defaults.\n\n**`shop/cli.py` \u2014 entry point, three pieces**\n\n- **`build_demo_order(inv)`**: constructs a hardcoded demo order \"D-1\" for customer \"demo\" in Greece with two lines: 2\u00d7 SKU-1 and 1\u00d7 SKU-2, priced at the current `unit_price` pulled from the inventory. This is demo scaffolding, not a real order path.\n- **`main(argv=None)`**: parses `sys.argv` (defaulting to `[]`). First it always builds `inv = Inventory(storage.load(\"data/catalogue.json\"))` \u2014 so loading happens before any command dispatch. If the first argument is `\"stock\"` it prints the stock report and returns 0. Otherwise it falls through to the default behavior: build the demo order, print `orders.order_total(order)` formatted to 2 decimals.\n- `if __name__ == \"__main__\": raise SystemExit(main())` \u2014 standard entry so `python -m shop.cli` works, and the exit code is the return value.\n\n**Fresh install with no `data/catalogue.json`**\n\nIt crashes with a `FileNotFoundError` traceback.

(README's `tests/acceptance.py` presumably builds products in memory.)\n\nSo on a truly fresh checkout, the first thing that happens is a traceback, not a friendly message or an empty report.
