See open Freshdesk tickets behind expiring 2Checkout subscriptions

**Objective:** List 2Checkout subscriptions expiring within the next `{days-ahead}` days (default 30) whose end users have unresolved Freshdesk tickets, so account owners can act before renewal.

**Step 1: Get expiring subscriptions**

Call `2checkout-get-subscription` with `expiration-date.from` set to today and `expiration-date.to` set to today plus `{days-ahead}` days. If `{product-name}` is given, pass it as `product-name`. Keep `subscription-reference`, `product-name`, `expiration-date`, `status` and `end-user-email`. Skip subscriptions with no `end-user-email`.

**Step 2: Check tickets for each email**

For each distinct `end-user-email`, call `freshdesk-get-tickets` with `requester-email` set to that value. Keep tickets whose `status` is not resolved or closed. Work through at most 25 emails, and say how many were left unchecked.

**Step 3: Report**

Table with end-user email, product, expiration date, open ticket count, highest priority and the oldest open `ticket-id`. Sort by expiration date, then by open ticket count. List separately the expiring subscriptions with no Freshdesk tickets.

**Rules & Guidelines:**

* `freshdesk-*` tools belong to the Freshdesk server; `2checkout-*` tools belong to the 2Checkout server. Both servers must be connected.
* The shared key across the two systems is the customer email address. Compare emails case-insensitively and trim spaces.
* Read-only. Do not call any 2Checkout write tool (for example `2checkout-subscription-extend` or `2checkout-subscription-renew`) and do not call any Freshdesk write tool.

**Validation:**

* If no subscription expires in the window, say so and stop.
* If an email has no Freshdesk tickets, count it as zero rather than as an error.
