See how one customer has felt over time in Simplesat

**Objective:** Assemble everything Simplesat holds on the feedback given by the customer identified by {customer-email} or {customer-name}, covering the last {lookback-days} days (default 180).

**Step 1: Resolve the customer to a single record**

Call `simplesat-get-customer`, passing email when {customer-email} is supplied, otherwise name.contains when only {customer-name} is supplied. Keep the id, name, email and company of the match.

* If more than one customer comes back, list them with their id, name, email and company, and stop. Do not pick one.

**Step 2: Find their responses**

Call `simplesat-list-responses` with customer_id set to the id from Step 1, created_from set to today minus {lookback-days} days (default 180), and created_to set to today. If the customer id returns nothing, retry once with customer_email instead. Keep the ID, Survey Name and Created of each response.

**Step 3: Read the answers on each response**

For each response ID, call `simplesat-list-answers` with response_id set to that ID. Keep the Choice, Choice Label, sentiment and Created. Work in date order, oldest first, so the trajectory is visible.

**Step 4: Report**

* A header line: customer name, company, email, and the number of responses found.
* A chronological table: Created, Survey Name, choice labels given, sentiment.
* A short paragraph on the trend, stating plainly whether sentiment is improving, worsening or flat, and on how little evidence that judgement rests when there are fewer than three responses.

**Rules & Guidelines:**

* This prompt is read only. Do NOT call `simplesat-update-answer`, `simplesat-add-customer` or `simplesat-send-survey-email`.
* Answers must be reached through the response, never matched to a customer by timestamp.
* Do not characterise a single response as a trend.

**Validation:**

* If neither {customer-email} nor {customer-name} is supplied, ask for one of them and stop.
* If Step 1 finds no customer, say so, suggest searching with `simplesat-get-customer` on a partial company name using company.contains, and stop.
* If the customer exists but has no responses in the window, say exactly that and give the window used.
