Show the stock you really have, straight from Sage Intacct

**Objective:** Update WooCommerce stock to match Intacct for SKU `{sku}` (default: every stock-managed product), using the Intacct `{quantity-basis}` quantity (on-hand or uncommitted, default on-hand) from warehouse `{warehouse-id}` (default: the item's total). Write nothing without the user's confirmation.

**Step 1: Read the WooCommerce stock**

If `{sku}` is set, call `woocommerce-get-product` with `sku` = `{sku}`, and if nothing matches, `woocommerce-get-product-variation` with `sku` = `{sku}`. Otherwise call `woocommerce-get-product` with `status` = publish and `max-records` = 500, and for each variable product call `woocommerce-get-product-variation` with its `product-id`.

Keep only rows with a SKU and a non-empty `stock-quantity`. A product with an empty `stock-quantity` does not manage stock: skip it and never switch stock management on.

**Step 2: Read the Intacct quantities**

If `{warehouse-id}` is set, call `intacct-get-item-warehouse` with `warehouse-id` = `{warehouse-id}` (and `item-id` = `{sku}` when set). Otherwise call `intacct-get-item` (with `item-id` = `{sku}` when set, or once with `max-records` = 2000). Match on `item-id` = SKU. Take `uncommitted` when `{quantity-basis}` is uncommitted, otherwise `on-hand`.

**Step 3: Build the change list**

For each matched SKU whose WooCommerce `stock-quantity` differs from the Intacct quantity, record: SKU, product name, product-id, variation id when it is a variation, current WooCommerce quantity, new quantity. Round the new quantity down to a whole number. If the Intacct quantity is negative, set it to 0 and flag it.

Also list SKUs with no Intacct match; they are left unchanged.

**Step 4: Confirm, then update**

Show the whole change list and the unmatched SKUs. If there are more than 50 changes, confirm and apply them in batches of 50. Only after a yes for a batch, for each change:

* a simple product: call `woocommerce-update-product` with `product-id` and `stock-quantity`;
* a variation: call `woocommerce-update-product-variation` with `product-id`, `variation-id` = the variation's `product-variation-id` and `stock-quantity`.

Pass no other field.

**Step 5: Confirm**

Report each update's result, then re-read the changed SKUs with `woocommerce-get-product` or `woocommerce-get-product-variation` and list any whose `stock-quantity` still differs from the target.

**Rules & Guidelines:**

* `woocommerce-get-product`, `woocommerce-get-product-variation`, `woocommerce-update-product` and `woocommerce-update-product-variation` are on the woocommerce server. `intacct-get-item` and `intacct-get-item-warehouse` are on the intacct server.
* The only write tools this prompt may call are `woocommerce-update-product` and `woocommerce-update-product-variation`, only for `stock-quantity`, and only after confirmation. Intacct is the source and is never written: do NOT call any intacct create or update tool. Do NOT change prices, status, `manage-stock` or `stock-status`.

**Validation:**

* If nothing differs, say stock is already in line and stop.
* If an update fails, show the error, skip that SKU, continue with the rest, and list the failures at the end.
* WooCommerce has already taken processing orders out of its stock that Intacct may still count as on hand. If the user syncs on-hand, warn that those units could be sold twice, and suggest uncommitted instead.
