 ## Key behaviours
-- **On load**: cookie credentials restored → GET webhook fires → dropdown populated → scan input auto-focused
+- **On load**: cookie credentials restored → GET webhooks fire (users + batches) → dropdown populated → scan input auto-focused
-- **Enter key**: trims input → duplicate check → clears input **immediately** → adds pending row → pushed onto FIFO queue → `drainQueue()` starts if idle
+- **Scan auto-submit**: scanner input is debounced at 100ms — typing a barcode and pausing auto-submits without needing Enter
+- **Scan auto-switches tab**: submitting a scan automatically switches to the Scan Log tab if the Batches tab is active
 - **Clear button**: empties the table, clears the scan input, resets the scan counter
 - **No user selected**: red toast + highlighted dropdown; does not submit
 - **401 on any request**: modal prompts for credentials (pre-filled from cookie), saves to cookie, retries original call
