+## L6 — toolbar polish (in-DAW feedback refinement on L5)
+**Goal:** Polish pass on the L5 dock-panel state based on Daniel's in-DAW feedback —
+single-row button faces, keybinding surfaced in the hover tooltip, Cancel RT moved into
+the overflow menu, and visible top-bar cluster order tidied. No new modules, no new test
+targets, no capture/placement behavior change.
+
+- [x] **Single-row button faces:** keybinding micro sub-row removed from `ActionBarSlot`
+  (and `bindingHeight`/`minSplitHeight` removed from `ActionBarSpec`); buttons now show
+  only the short label. Toolbar height 40→28 px.
+- [x] **Keybinding in hover tooltip:** tooltip now renders "`phrase — binding`" when the
+  action is bound, bare phrase when unbound (live binding via `kbd_getTextFromCmd`).
+- [x] **Cancel RT moved into overflow menu:** the More (⋯) popup now lists four entries —
+  Batch Items / Batch Razor / Capture RT / Cancel RT. The visible top bar no longer has a
+  Cancel RT button.
+- [x] **Visible top-bar cluster order:** Capture Item · Capture Track · Re-capture · Insert ·
+  Insert Conform (cluster order: Capture → Maintenance → Placement).
+
+**Notes/decisions:**
+- Icons were considered and deferred (not implemented in this pass).
