See every Chorus conversation with a donor in one timeline

**Objective:** Build a timeline of every Chorus conversation and email involving the DonorPerfect donor `{donor}` over the last `{lookback-days}` days (default 180).

**Step 1: Identify the donor in DonorPerfect**

If `{donor}` is a whole number, call `donorperfect-get-donor` with it as donor-id. Otherwise treat it as an email address and call `donorperfect-get-donor` with it as email. If more than one donor comes back, list them (donor-id, name, organization-name, email) and stop. If none comes back, say so and stop.

Collect every email address for the donor: the email on the donor record, plus the email on each row from `donorperfect-get-address` filtered by donor-id. Note the organization-name if there is one.

**Step 2: Find the donor's conversations in Chorus**

For each email address, call `chorus-get-conversation-participants` filtered by email and collect the distinct conversation-id values. For each conversation-id, call `chorus-get-engagements` with conversation-id and keep only those whose date falls inside the lookback window.

For each email address, also call `chorus-get-emails` with it as initiator-email and sent-time.from set to the start of the window.

If the donor has an organization-name, call `chorus-get-engagements` with account-name.contains set to it and date.from set to the start of the window, and add any conversations not already found. Mark these as matched by organization name, not by email.

**Step 3: Report**

One header line: donor-id, name, organization-name, emails searched.

Then a table in date order: date, type (call, meeting or email), subject, Chorus owner (user-name or owner-name), matched by (email or organization), and a one-line summary taken from meeting-summary or the email body.

End with totals: conversations, emails, and the date of the most recent touch.

**Rules & Guidelines:**

* Tools named donorperfect-... are on the donorperfect server. Tools named chorus-... are on the chorus server.
* This prompt is read-only. Do NOT call any DonorPerfect write tool (`donorperfect-save-donor`, `donorperfect-save-contact`, `donorperfect-save-gift`, `donorperfect-save-pledge`, `donorperfect-save-address`, `donorperfect-save-other-info`, `donorperfect-save-link`, `donorperfect-set-flag`) or any Chorus write tool (`chorus-add-moment`, `chorus-add-playlist-moment`, `chorus-create-playlist`, `chorus-update-moment`, `chorus-update-playlist`, `chorus-update-playlist-moment`, `chorus-export-recordings`, `chorus-export-scorecards`).
* Match emails case-insensitively and ignore surrounding whitespace.

**Validation:**

* If the donor has no email address and no organization-name, say that Chorus cannot be searched for this donor and stop.
* If Chorus returns nothing for any email, report the donor as having no recorded conversations in the window. Do not widen the search to name matching.
* If an organization-name match returns conversations that look unrelated (a different account that merely contains the name), list them separately as possible matches rather than in the timeline.
