 - Added full Telegram reference mapping checklist (`docs/android-ui-batch-4-checklist.md`) with screenshot-by-screenshot description.
 - Added explicit icon policy: no emoji icons in production UI components, Material Icons/vector icons only.
 - Updated UI checklist index with Batch 4 entry.
+
+### Step 75 - Material Icons migration (Batch 1 start)
+- Replaced symbol/emoji-based UI controls in chat surfaces with Material Icons:
+  - chat header/menu/search controls (`more`, `up/down`),
+  - image viewer actions (`close`, `forward`, `delete`),
+  - multi-select markers (`radio checked/unchecked`, `selected` check),
+  - attachment/media markers (`movie`, `attach file`).
+- Replaced chat list management FAB glyph toggle (`+`/`×`) with Material `Add`/`Close` icons.
+- Added `androidx.compose.material:material-icons-extended` dependency for consistent icon usage.
