 ## [Unreleased]
 
+### Fixed
+- **Admin: empty confirm dialog on auto-poll** — `htmx:confirm` handler now guards with `if (!evt.detail.question) return` so auto-poll requests (`hx-trigger="every 5s"`, no `hx-confirm` attribute) no longer trigger an empty dialog every 5 seconds.
+
 ### Changed
 - **Admin: styled confirm dialog for all destructive actions** — replaced all native `window.confirm()` calls with the existing `#confirm-dialog` styled `<dialog>`. A new global `htmx:confirm` handler intercepts HTMX confirmation prompts and shows the dialog; form-submit buttons on affiliate pages were updated to use `confirmAction()`. Affected: pipeline Transform tab (Run Transform, Run Export, Run Full Pipeline), pipeline Overview tab (Run extractor), affiliate product delete, affiliate program delete (both form and list variants).
 - **Pipeline tabs: no scrollbar** — added `scrollbar-width: none` and `::-webkit-scrollbar { display: none }` to `.pipeline-tabs` to suppress the spurious horizontal scrollbar on narrow viewports.
