+## Phase 9: Touch Input & App Launcher Integration
+
+**Date**: 2 Mars 2026
+**Status**: 🚀 READY FOR EXECUTION
+
+### Validation Results
+
+✅ **Device Responsiveness**: PING/PONG working, STATUS complete
+✅ **Firmware Stability**: No memory leaks, commands responsive
+✅ **AmigaUIShell Boot**: Initialized in main.cpp setup()
+✅ **System Ready**: All P1/P2 security features active
+
+---
+
+### Phase 9 Scope
+
+#### 1. Touch Input Mapping (HIGH PRIORITY)
+
+**Current State**:
+- AmigaUIShell::selectApp(0-7) method defined
+- Grid layout: 4x4 = 16 possible positions, using 7 apps
+- Touch manager exists (g_touch) with coordinate input
+
+**Implementation**:
+```cpp
+// Map touch coordinates to grid index
+uint8_t grid_index = calculateGridIndex(touch_x, touch_y);
+if (grid_index < 7) {
+  g_amiga_shell.selectApp(grid_index);  // Select app (highlight)
+  // Visual feedback: pulse effect
+}
+```
+
+**Grid Layout** (assuming 320x200 display):
+```
+┌──────┬──────┬──────┬──────┐  (0,0)→(64,64)
+│  [0] │  [1] │  [2] │  [3] │  Audio, Calc, Timer, Light
+├──────┼──────┼──────┼──────┤  (0,80)→(64,144)
+│  [4] │  [5] │  [6] │  --- │  Camera, Dict, QR, ---
+├──────┼──────┼──────┼──────┤
+│      │      │      │      │
+└──────┴──────┴──────┴──────┘
+```
+
+**Coordinate Calculation**:
+```cpp
+uint8_t AmigaUIShell::getTouchGridIndex(uint16_t x, uint16_t y) {
+  uint8_t col = x / (ICON_SIZE + ICON_SPACING);  // 64 + 16 = 80px per cell
+  uint8_t row = y / (ICON_SIZE + ICON_SPACING);
+  
+  if (col >= GRID_COLS || row >= GRID_ROWS) return 255;  // Out of bounds
+  
+  uint8_t index = row * GRID_COLS + col;
+  return (index < 7) ? index : 255;  // Only 7 apps available
+}
+```
+
+#### 2. Button Integration (MEDIUM PRIORITY)
+
+**Current State**:
+- ButtonManager::readButtons() returns button states
+- 4 buttons available (from RC_FINAL_BOARD.md)
+
+**Mapping**:
+```
+Button 0 (UP):      Move selection up (previous row)
+Button 1 (SELECT):  Launch selected app
+Button 2 (DOWN):    Move selection down (next row)
+Button 3 (MENU):    Return to launcher (if in app)
+```
+
+**Implementation**:
+```cpp
+void handleButtonPress(uint8_t button_id) {
+  if (button_id == BUTTON_UP) {
+    uint8_t new_index = (g_amiga_shell.selected_index_ >= 4) 
+                        ? g_amiga_shell.selected_index_ - 4 
+                        : g_amiga_shell.selected_index_;
+    g_amiga_shell.selectApp(new_index);
+  }
+  else if (button_id == BUTTON_SELECT) {
+    g_amiga_shell.launchSelectedApp();
+  }
+  // ... etc
+}
+```
+
+#### 3. App Launch Mechanism (HIGH PRIORITY)
+
+**Current State**:
+- launchSelectedApp() defined but empty
+- App registry exists with 4 core apps
+- AppCoordinator arch exists (from spec)
+
+**Implementation**:
+```cpp
+void AmigaUIShell::launchSelectedApp() {
+  if (selected_index_ >= 7) return;
+  
+  const AppIcon& app = APPS[selected_index_];
+  Serial.printf("[UI_AMIGA] Launching app: %s\n", app.app_id);
+  
+  // Transition effect (fade out)
+  playTransitionFX();
+  
+  // TODO: Route to AppCoordinator
+  // dispatch AppAction::LAUNCH to app identified by app.app_id
+  // AppCoordinator::launchApp(app.app_id, context);
+  // Switch UI mode from LAUNCHER to APP_RUNNING
+}
+```
+
+#### 4. Return-to-Launcher Flow (MEDIUM PRIORITY)
+
+**Mechanism**:
+- App finish → onStop() called
+- AppCoordinator signals launcher
+- AmigaUIShell::onStart() called again
+- Grid redraws with previous selection preserved
+
+---
+
+### Implementation Checklist
+
+**Phase 9A: Touch/Button Input (Immediate)**
+- [ ] Implement getTouchGridIndex() in ui_amiga_shell.cpp
+- [ ] Add onTouchEvent() handler
+- [ ] Add handleButtonPress() for grid navigation
+- [ ] Test: Tap on grid → see selection highlight
+- [ ] Test: Button UP/DOWN → selection moves
+
+**Phase 9B: App Launch (Urgent)**
+- [ ] Implement launchSelectedApp() logic
+- [ ] Route to AppCoordinator (when available)
+- [ ] Implement return-to-launcher flow
+- [ ] Test: Select app → launch and run
+- [ ] Test: App stop → return to launcher
+
+**Phase 9C: Visual Polish (Nice-to-have)**
+- [ ] Smooth animation transitions
+- [ ] Delayed app launch (allow fade-out to complete)
+- [ ] Selection wraparound (grid navigation loops)
+- [ ] Long-press to see app info (future)
+
+---
+
+### Known Issues & Workarounds
+
+**Issue**: 2 DALL-E icons still missing (audio_player, timer)
+**Workaround**: Emoji fallbacks (🎵, ⏱️) render gracefully
+**Next**: Retry DALL-E generation once quota resets
+
+**Issue**: AppCoordinator integration pending
+**Status**: Phase 9B blocked until AppCoordinator available
+**Fallback**: Can test launcher UI in isolation first
+
+---
+
+### Testing Strategy
+
+**Unit Tests**:
+1. `getTouchGridIndex(x, y)` → correct grid_index
+2. `selectApp(index)` → selected_index_ updated, pulse effect triggered
+3. `launchSelectedApp()` → transition FX played + app launch signal sent
+
+**Integration Tests**:
+1. Touch grid → app selection flowmap
+2. Button navigation → grid highlight moves
+3. App launch → transition → app runs → return to launcher
+
+**Hardware Tests**:
+1. On live device: Tap/touch grid positions
+2. Button presses: UP/DOWN/SELECT navigation
+3. App launch: Start → run → stop → back to launcher
+
+---
+
+### Questions for Implementation
+
+1. **Touch resolution**: Is touch input (x, y) available in UiManager?
+2. **AppCoordinator**: Does it exist? Can we call it from AmigaUIShell?
+3. **App registry**: Are app_id strings correct? (e.g., "audio_player" vs "app_audio")
+4. **Display size**: Is display 320x200? Need to confirm grid offsets
+
+---
+
+### Dependencies
+
+- ✅ AmigaUIShell class (Phase 8)
+- ✅ UiManager with touch support (existing)
+- ✅ ButtonManager (existing)
+- ❓ AppCoordinator (Phase 9B requires)
+- ❓ App lifecycle integration (Phase 9B requires)
+
+---
+
+### Success Criteria
+
+✅ **Phase 9 Complete When**:
+1. Touch coordinates map to grid positions ✓
+2. Grid selection updates visually on input ✓
+3. Button navigation works (UP/DOWN/SELECT) ✓
+4. App launch transitions smoothly ✓
+5. Return-to-launcher flow functional ✓
+6. No memory leaks or crashes after 10 launches ✓
+
+---
+
+### Timeline
+
+- Phase 9A (Touch/Button): 1-2 hours
+- Phase 9B (App Launch): 2-3 hours
+- Phase 9C (Polish): 1 hour
+- Total Phase 9: ~4-6 hours
+
+**Estimate complete by**: 2-3 hours from now (if proceeding immediately)
