Know which major Bloomerang donors Constant Contact actually reaches

**Objective:** For Bloomerang donors with at least one gift of {min-amount} or more in the last {lookback-days} days (default 365), report whether Constant Contact can reach them and whether they are engaging.

**Step 1: Find the donors in Bloomerang**

Call `bloomerang-get-transaction` with `amount.min` and `date.from` set to today minus the lookback days. Skip refunded transactions. Group by account-id and total each donor's gifts in the window. For each account-id, call `bloomerang-get-constituent` with `id` for full name, account number, status and engagement score, and `bloomerang-get-email-address` with `account-id` for every address and its bad flag.

**Step 2: Check each address in Constant Contact**

For each email, call `constant-contact-get-contact` with `email-address`. If found, keep permission-to-send and contact-id, then with `created-date.from` set to the same start date call `constant-contact-get-campaign-bounce` and `constant-contact-get-contact-activity` with `contact-id`.

**Step 3: Classify each donor**

Use the best of the donor's addresses:

* Engaged: can be emailed and has opens or clicks in the window
* Not engaging: can be emailed, no opens or clicks
* Unsubscribed: permission-to-send is unsubscribed on every matched address
* Bouncing: every matched address has bounced, or is flagged bad in Bloomerang
* Not in Constant Contact: has an email in Bloomerang that Constant Contact does not have
* No email: no email address in Bloomerang

**Step 4: Report**

Counts per group, then one table per group: full name, account number, total given in the window, email, most recent open or click date. Sort each table by total given, largest first. Close with one line noting that donors Not in Constant Contact can be added with the sync-donors-to-constant-contact prompt.

**Rules & Guidelines:**

* Bloomerang tools: `bloomerang-get-transaction`, `bloomerang-get-constituent`, `bloomerang-get-email-address`. Constant Contact tools: `constant-contact-get-contact`, `constant-contact-get-campaign-bounce`, `constant-contact-get-contact-activity`.
* This prompt is read-only. Do not call `constant-contact-add-contact`, `constant-contact-update-contact`, `bloomerang-add-task` or `bloomerang-add-interaction`.
* The minimum applies to single gifts, not to a donor's total. Say so in the report.
* Match emails case-insensitively after trimming spaces. Never match on name alone.
* The Bloomerang constituent `id` is the same number every other Bloomerang tool takes as `account-id`.
**Validation:**

* If no gifts meet the minimum, say so and stop.
* If more than 100 donors qualify, process the largest givers first and report how many were not checked.
