See one customer's tickets and feedback as one story

**Objective:** Build a combined history for the customer with email `{customer-email}`: their Zendesk tickets and their Simplesat feedback, looking back `{lookback-days}` days (default 90).

**Step 1: Identify the customer in Zendesk**

Call `zendesk-get-user` with `email` = {customer-email}. If more than one user comes back, list them and stop. If none comes back, note "not a Zendesk user" and continue to Step 3.

**Step 2: Their tickets**

Call `zendesk-get-ticket` with `requester-email` = {customer-email} and `created.from` set to {lookback-days} days before today.

**Step 3: Identify the customer in Simplesat**

Call `simplesat-get-customer` with `email` = {customer-email}. Compare emails case-insensitively; Zendesk and Simplesat may store different capitalisation.

**Step 4: Their feedback**

Call `simplesat-list-responses` with `customer_email` = {customer-email} and `created_from` set to the same date as Step 2. For each response, call `simplesat-list-answers` with `response_id` = the response's `ID`.

**Step 5: Report**

* Who they are: name, organization, role and open-ticket count from Zendesk; name and company from Simplesat. Flag any difference in name or company between the two.
* A single timeline, oldest first, mixing tickets (id, subject, status, created date) and survey responses (survey name, date, sentiment, comment).
* Totals: tickets opened, tickets still open, responses, and the count of negative answers.

**Rules & Guidelines:**

* `zendesk-get-user` and `zendesk-get-ticket` are on the zendesk server. `simplesat-get-customer`, `simplesat-list-responses` and `simplesat-list-answers` are on the simplesat server.
* This prompt is read-only. Do NOT call `zendesk-update-user`, `zendesk-update-ticket`, `simplesat-add-customer` or `simplesat-send-survey-email`.

**Validation:**

* If the customer is found in neither system, say so and stop.
* If they are in one system only, report what that system has and state which system has no record.
