+## Closing a Ticket With a Mandatory Comment
+
+The ticket status control now enforces an auditable closure workflow.
+
+### How to close a ticket
+
+1. Open the Helpdesk ticket.
+2. Open **Ticket controls**.
+3. Change **Status** to a closed status, for example **Closed**.
+4. Click **Update status**.
+5. The **Close ticket** dialog opens if no closure comment has been entered.
+6. Enter a clear closure comment explaining what was resolved or why the ticket is being closed.
+7. Leave **Internal closure note** unticked when the customer/requester should see the closure response.
+8. Tick **Internal closure note** only when the closure reason is staff-only.
+9. Click **Close ticket**.
+
+### Closure comment rules
+
+- A closed status cannot be saved without a closure comment.
+- The closure comment must be at least 10 characters.
+- Public closure comments are saved as normal Helpdesk responses.
+- Internal closure comments are saved as internal notes and are only visible to users allowed to see internal notes.
+- The ticket `completed_at` timestamp is set when a closed status is saved successfully.
+- The resolution SLA is recorded after the closure is saved.
+
+### Recommended closure wording
+
+```text
+Issue resolved and verified.
+
+The requested work has been completed and no further action is currently required. This ticket is now closed.

     - Documented Public Reply versus Internal Note usage for responses and SLA handling.

+- version: 1.9.38
+  date: 2026-06-23
+  type: bugfix
+  summary: Enforce mandatory closure comments when closing Helpdesk tickets.
+  changes:
+    - Added a close-ticket confirmation dialog that opens when a closed status is selected without a closure comment.
+    - Added server-side validation so closed statuses cannot be saved without a meaningful closure comment.
+    - Stored the closure comment as a Helpdesk response with Public Reply as the default visibility and Internal Note as an explicit option.
+    - Updated the status control UI with closed-status metadata and accessible modal controls.
+    - Added regression tests for blocked closure without a comment and successful closure with an auditable comment.
+    - Preserved append-only changelog history.

+- version: 1.9.39
+  date: 2026-06-23
+  type: bugfix
+  summary: Fix Helpdesk ticket create editor body synchronisation.
+  changes:
+    - Updated the ticket creation rich-text Details editor so content is pushed into the Livewire body property before validation.
+    - Added Livewire navigation-safe editor initialisation so the sync logic works after wire:navigate page changes.
+    - Added input, keyup, paste, blur, and submit-capture synchronisation to prevent false "body field is required" validation failures.
+    - Changed the hidden body field to live Livewire binding so the server receives the latest editor content without requiring a page reload.
+    - Preserved append-only changelog history.
