 - **Propagation node sync**: Tapping **Sync Messages** no longer shows technical state names in the top bar (e.g. `path_requested`). The bar shows a simple **Syncing...** label while a **live toast** explains what is happening in plain language and shows **progress** until the sync finishes or stops. Success and error toasts still summarize how many messages were received, stored, confirmed, or hidden.
 - **Dark theme**: Accent colors in dark mode are adjusted for more consistent look and feel.
 - **Announcements**: Automatic announce and related timers use clearer **due** checks; behaviour should be easier to reason about and test.
+- **Frontend structure**: Settings and conversation logic are split into reusable JS modules and smaller Vue pieces (banners, peer header, settings sections) to make the UI easier to maintain and test.
+- **Android APK support**: MeshChatX now builds and runs as a native Android APK (embedded Python backend via Chaquopy + WebView), so Android support is no longer limited to Termux workflows.
 
 ### Platform and backend
 
 - **MeshChat utils**: **`convert_propagation_node_state_to_string`** maps **`LXMRouter.PR_PATH_TIMEOUT`** to **`path_timeout`** so the API can report path timeouts distinctly from other failures.
 - **Auto-announce / intervals**: Refactor around **`interval_action_due`** in **`meshchat.py`** to simplify when auto-announce and propagation sync checks run; add tests for auto-announce behaviour.
+- **Android runtime integration**: Added Android app startup hardening for Chaquopy and WebView, including startup retries, in-app startup errors, runtime permission flow (audio/Bluetooth/notifications), selectable error text, launcher icon integration, and release minification rules for APK builds.
 
 ### Frontend and UX
 
 - **Propagation sync (App header)**: After **`GET /api/v1/lxmf/propagation-node/sync`**, the client **polls** propagation status on an interval while the router is in a transfer state, updates a **keyed loading toast** (`propagation-sync-status`) with translated strings (**`app.propagation_sync_live`**, **`app.propagation_sync_state.*`**), dismisses it when the transfer ends, then shows the existing success or error summary. Stopping sync clears the poll timer and dismisses the live toast; **beforeUnmount** cleans up if you leave the page mid-sync. Removed the old toolbar pattern **`Syncing... ({state})`** in favour of **`app.syncing`** plus the toast.
 - **Theme**: Dark theme accent palette updates for consistency; tests adjusted where they assert colors.
+- **Modularity (settings and messages)**: Config fetch/merge, **`PATCH /api/v1/config`**, color normalization, transport enable/disable, maintenance HTTP calls, and visualiser **`localStorage`** prefs live in **`meshchatx/src/frontend/js/settings/`** (`settingsConfigService`, `settingsTransportService`, `settingsMaintenanceClient`, `settingsVisualiserPrefs`); **`SettingsPage`** delegates to those modules. Message renderability, telemetry-only detection, image-only detection, and drag/paste image extraction are in **`conversationMessageHelpers.js`** with thin **`ConversationViewer`** wrappers.
+- **Shell and settings UI**: Emergency and WebSocket status banners extracted to **`AppShellBanners.vue`**; conversation peer chrome to **`ConversationPeerHeader.vue`**; reusable **`SettingsSectionBlock.vue`** (used for the stranger-protection section). **`frontendModuleMap.js`** summarizes main frontend layers and hotspots for contributors.

 ### Testing and docs
 
 - **Frontend**: **`AppPropagationSync.test.js`** covers immediate completion (no stray loading toast), polling with **`path_requested`** and live **`ToastUtils.loading`**, and **`no_path`** end states with translated error text; **`AppModals`** / **`ChangelogModal`** tests updated where changelog content or expectations shifted.
+- **Frontend (modularization)**: Shared **`tests/frontend/fixtures/settingsPageTestApi.js`** for **`buildFullServerConfig`** / **`window.api`** mocks; unit tests for **`settingsConfigService`** and **`conversationMessageHelpers`**; **`SettingsSectionBlock`** stubbed in settings-related tests; overlapping **IconButton** cases removed from **`UIComponents.test.js`** (covered by **`IconButton.test.js`**).
 - **Backend**: **`test_lxmf_propagation_full.py`** adds **`path_timeout`** in status mapping, **`test_convert_propagation_node_state_maps_all_lxmf_transfer_states`** for LXMF propagation transfer constants, and Hypothesis **`path_timeout`** in allowed propagation state strings; **`test_app_status_tracking`** expects **`changelog_seen_version`** **4.5.0** in app status tests.
