See what Drip campaign members bought in WooCommerce

**Objective:** Measure WooCommerce purchases made in the last `{lookback-days}` days (default 30) by the people in the Drip campaign matching `{campaign-name}`.

**Step 1: Find the Drip campaign**

Call `drip-get-campaign` with `name.contains` set to `{campaign-name}`. If none or several match, list them and stop. Note the campaign-id, status, created date and active subscriber count.

**Step 2: List its members**

Call `drip-get-campaign-subscriber` with `campaign-id` set to the campaign's id and `max-records` set to 500. Note each member's email and campaign status.

**Step 3: Read their orders**

Use as the start date whichever is later: the campaign's created date or today minus `{lookback-days}` days. For each member, call `woocommerce-get-order` with `customer-email` set to their email and `created-date.from` set to that date. If there are more than 100 members, check the first 100 and say so.

**Step 4: Report**

- Campaign: name, status, start date used, members checked
- Buyers: how many members ordered, as a count and a percentage of members checked
- Revenue: order count and total per currency, excluding cancelled, failed and refunded orders
- Top 10 buyers by total spent, with order count
- Members who left: buyers whose campaign status is no longer active

**Rules & Guidelines:**

* Tools whose names start with drip- are on the drip server; tools whose names start with woocommerce- are on the woocommerce server. Both servers must be connected.
* Match people across the two systems by email, compared case-insensitively with surrounding spaces removed. Drip uses `email`; WooCommerce uses `email` on customers and `customer-email` on orders, order lines and refunds.
* Compute dates as today minus the stated number of days and pass them as YYYY-MM-DD.
* This prompt is read-only. Do not call any write tool on either server, including `drip-add-subscriber`, `drip-update-subscriber`, `drip-add-subscriber-tag`, `drip-remove-subscriber-tag`, `drip-add-subscriber-to-campaign`, `drip-unsubscribe-subscriber`, `woocommerce-update-customer`, `woocommerce-update-order`, `woocommerce-add-order-note` or `woocommerce-add-refund`.
* Present the result as purchases by campaign members, not as revenue caused by the campaign; this data cannot show causation.

**Validation:**

* If the campaign has no members, say so and stop.
* If no member ordered in the period, report zero buyers rather than stopping.
* Never add amounts in different currencies together; total each currency separately.
