+Real \`SessionRevertDock\` from app code, rendered above a mock composer card.
+
+### Source path
+- \`packages/app/src/pages/session/composer/session-revert-dock.tsx\`
+
+### Why the mock composer
+The live composer overlaps the dock's bottom by 18px (\`session-composer-region-controller.ts\` \`lift()\`).
+The card below reproduces that overlap so the collapsed/expanded cutoff behavior can be verified in isolation.
+
+### Layout split
+Use the **Layout** button to toggle \`newLayoutDesigns\` and preview both the v2 dock and the legacy (v1) \`DockTray\` fallback.
+
+### Notes
+- \`onRestore\` only mutates local story state, so nothing in the real session is affected.
+- Click the header to expand/collapse. Click "Restore message" to remove a row.`,
