 The `pf_bucket` datalist on the Baseline page was already per version
 (`bucketsInUse`), so the two now agree.
 
+**Completion is the datalist and nothing else.** The operation panel used to
+carry six quick-pick pills under the tag field as well. They wrapped to two rows
+as soon as the tags were longer than a word, and the panel docked at the bottom
+has a fixed height, so they pushed the form past its own border. The datalist
+costs no space, is not capped at six, and now shows the tag alone — an option's
+text content renders as a second column beside the value, so the use count was
+widening every row of the pick list to carry a number nobody picks on. `uses`
+and `last_used` still come back from the route; nothing reads them.
