+To fix the issue of the filename truncating due to a hardcoded `max-width` of `128px` in the Changes panel of Vibe mode, you can modify the CSS to make the filename span responsive. Here's the exact code fix:
+
+```css
+/* Remove the hardcoded max-width */
+.changes-panel .filename {
+  max-width: none;
+  overflow: hidden;
+  text-overflow: ellipsis;
+  white-space: nowrap;
+}
+
+/* Make the filename span responsive */
+.changes-panel .filename {
+  width: 100%;
+  box-sizing: border-box;
+}
+
+/* Alternatively, you can use a more flexible layout */
+.changes-panel {
+  display: flex;
+  flex-direction: row;
+}
+
+.changes-panel .filename {
+  flex-grow: 1;
+  overflow: hidden;
+  text-overflow: ellipsis;
+  white-space: nowrap;
+}
+```
+
+This code removes the hardcoded `max-width` and makes the filename span responsive by setting its width to `100%` or using a flexible layout with `flex-grow: 1`. This will allow the filename to resize based on the available panel width, preventing truncation and making it easier to identify the full changed file name.
