+## Changelog & First Launch System
+
+The app includes a comprehensive system for welcoming new users and notifying existing users of updates.
+
+### Components
+- **ChangelogService**: Manages version tracking and changelog loading
+- **WelcomeDialog**: First launch popup with privacy information and quick links
+- **ChangelogDialog**: Update notification popup for version changes  
+- **ReleaseNotesScreen**: Settings page for viewing all changelog history
+
+### Content Management
+Changelog content is stored in `assets/changelog.json`:
+```json
+{
+  "1.2.4": {
+    "content": "• New feature description\n• Bug fixes\n• Other improvements"
+  },
+  "1.2.3": {
+    "content": ""  // Empty string = skip popup for this version
+  }
+}
+```
+
+### Developer Workflow
+1. **For each release**: Add entry to `changelog.json` with version from `pubspec.yaml`
+2. **Content required**: Every version must have an entry (can be empty string to skip)
+3. **Localization**: Welcome dialog supports i18n, changelog content is English-only
+4. **Testing**: Clear app data to test first launch, change version to test updates
+
+### User Experience Flow
+- **First Launch**: Welcome popup with "don't show again" option
+- **Version Updates**: Changelog popup (only if content exists, no "don't show again")  
+- **Settings Access**: Complete changelog history available in Settings > About > Release Notes
+
+### Privacy Integration
+The welcome popup explains that the app:
+- Runs entirely locally on device
+- Uses OpenStreetMap API for data storage only
+- DeFlock collects no user data
+- DeFlock is not responsible for OSM account management

 ## Core Components
 
-### 1. MapDataProvider
+### 1. MapDataProvider & Smart Area Caching
 
-**Purpose**: Unified interface for fetching map tiles and surveillance nodes
+**Purpose**: Unified interface for fetching map tiles and surveillance nodes with intelligent area caching
 
 **Design decisions:**
-- **Pluggable sources**: Local (cached) vs Remote (live API)
-- **Offline-first**: Always try local first, graceful degradation
+- **Single fetch strategy**: Uses PrefetchAreaService for smart 3x area caching instead of dual immediate/background fetching
+- **Spatial + temporal refresh**: Fetches larger areas (3x visible bounds) and refreshes stale data (>60s old)
+- **Offline-first**: Always try local cache first, graceful degradation
 - **Mode-aware**: Different behavior for production vs sandbox
 - **Failure handling**: Never crash the UI, always provide fallbacks
 
 **Key methods:**
-- `getNodes()`: Smart fetching with local/remote merging
-- `getTile()`: Tile fetching with caching
+- `getNodes()`: Returns cache immediately, triggers pre-fetch if needed (spatial or temporal)
+- `getTile()`: Tile fetching with enhanced retry strategy (6 attempts, 1-8s delays)
 - `_fetchRemoteNodes()`: Handles Overpass → OSM API fallback
 
-**Why unified interface:**
-The app needs to seamlessly switch between multiple data sources (local cache, Overpass API, OSM API, offline areas) based on network status, upload mode, and zoom level. A single interface prevents the UI from needing to know about these complexities.
+**Smart caching flow:**
+1. Check if current view within cached area AND data <60s old
+2. If not: trigger pre-fetch of 3x larger area, show loading state
+3. Return cache immediately for responsive UI
+4. When pre-fetch completes: update cache, refresh UI, report success
+
+**Why this approach:**
+Reduces API load by 3-4x while ensuring data freshness. User sees instant responses from cache while background fetching keeps data current. Eliminates complex dual-path logic in favor of simple spatial/temporal triggers.
 
 ### 2. Node Operations (Create/Edit/Delete)
 
@@ -95,10 +148,29 @@ enum UploadOperation { create, modify, delete }
 - **Clear intent**: `operation == UploadOperation.delete` is unambiguous
 
 **Session Pattern:**
-- `AddNodeSession`: For creating new nodes
-- `EditNodeSession`: For modifying existing nodes
+- `AddNodeSession`: For creating new nodes with single or multiple directions
+- `EditNodeSession`: For modifying existing nodes, preserving all existing directions
 - No "DeleteSession": Deletions are immediate (simpler)
 
+**Multi-Direction Support:**
+Sessions use a simple model for handling multiple directions:
+```dart
+class AddNodeSession {
+  List<double> directions;          // [90, 180, 270] - all directions
+  int currentDirectionIndex;        // Which direction is being edited
+  
+  // Slider always shows the current direction
+  double get directionDegrees => directions[currentDirectionIndex];
+  set directionDegrees(value) => directions[currentDirectionIndex] = value;
+}
+```
+
+**Direction Interaction:**
+- **Add**: New directions start at 0° and are automatically selected for editing
+- **Remove**: Current direction removed from list (minimum 1 direction)
+- **Cycle**: Switch between existing directions in the list
+- **Submit**: All directions combined as semicolon-separated string (e.g., "90;180;270")
+
 **Why no delete session:**
 Deletions don't need position dragging or tag editing - they just need confirmation and queuing. A session would add complexity without benefit.

 These are internal app tags, not OSM tags. The underscore prefix makes this explicit and prevents accidental upload to OSM.

 - **Production (Overpass)**: Zoom ≥ 10 (established limit)
 - **Sandbox (OSM API)**: Zoom ≥ 13 (stricter due to bbox limits)
 
-**Why different zoom limits:**
-The OSM API returns ALL data types (nodes, ways, relations) in a bounding box and has stricter size limits. Overpass is more efficient for large areas. The zoom restrictions prevent API errors and excessive data transfer.
+**Smart error handling & splitting:**
+- **50k node limit**: Automatically splits query into 4 quadrants, recursively up to 3 levels deep
+- **Timeout errors**: Also triggers splitting (dense areas with many profiles)  
+- **Rate limiting**: Extended backoff (30s), no splitting (would make it worse)
+- **Surgical detection**: Only splits on actual limit errors, not network issues
+
+**Query optimization:**
+- **Pre-fetch limit**: 4x user's display limit (e.g., 1000 nodes for 250 display limit)
+- **User-initiated detection**: Only reports loading status for user-facing operations  
+- **Background operations**: Pre-fetch runs silently, doesn't trigger loading states
+
+**Why this approach:**
+Dense urban areas (SF, NYC) with many profiles enabled can easily exceed both 50k node limits and 25s timeouts. Splitting reduces query complexity while surgical error detection avoids unnecessary API load from network issues.
 
 ### 6. Offline vs Online Mode Behavior
 
@@ -165,6 +264,87 @@ Sandbox + Offline    → No nodes (cache is production data)
 **Why sandbox + offline = no nodes:**
 Local cache contains production data. Showing production nodes in sandbox mode would be confusing and could lead to users trying to edit production nodes with sandbox credentials.
 
+### 7. Proximity Alerts & Background Monitoring
+
+**Design approach:**
+- **Simple cooldown system**: In-memory tracking to prevent notification spam
+- **Dual alert types**: Push notifications (background) and visual banners (foreground)
+- **Configurable distance**: 25-200 meter alert radius
+- **Battery awareness**: Users explicitly opt into background location monitoring
+
+**Implementation notes:**
+- Uses Flutter Local Notifications for cross-platform background alerts
+- Simple RecentAlert tracking prevents duplicate notifications
+- Visual callback system for in-app alerts when app is active

+- **Separate from follow mode**: North lock is independent of GPS following behavior  
+- **Smart rotation detection**: Distinguishes intentional rotation (>5°) from zoom gestures
+- **Visual feedback**: Clear skeumorphic compass design with red north indicator
+- **Mode awareness**: Disabled during follow+rotate mode (incompatible)
+
+**Key behaviors:**
+- **North indicator**: Red arrow always points toward true north regardless of map rotation
+- **Tap to toggle**: Enable/disable north lock with visual animation to north
+- **Auto-disable**: North lock turns off when switching to follow+rotate mode
+- **Gesture intelligence**: Only disables on significant rotation changes, ignores zoom artifacts
+
+**Visual states:**
+- **Normal**: White background, grey border, red north arrow
+- **North locked**: White background, blue border, bright red north arrow
+- **Disabled**: Grey background, muted colors (during follow+rotate mode)
+
+**Why separate from follow mode:**
+Users often want to follow their location while keeping the map oriented north. Previous "north up" follow mode was confusing because it didn't actually keep north up. This separation provides clear, predictable behavior.
+
+### 9. Suspected Locations
+
+**Data pipeline:**
+- **CSV ingestion**: Downloads utility permit data from alprwatch.org
+- **Dynamic field parsing**: Stores all CSV columns (except `location` and `ticket_no`) for flexible display
+- **GeoJSON processing**: Handles Point, Polygon, and MultiPolygon geometries
+- **Proximity filtering**: Hides suspected locations near confirmed devices
+- **Regional availability**: Currently select locations, expanding regularly
+
+**Display approach:**
+- **Required fields**: `ticket_no` (for heading) and `location` (for map positioning)
+- **Dynamic display**: All other CSV fields shown automatically, no hardcoded field list
+- **Server control**: Field names and content controlled server-side via CSV headers
+- **Brutalist rendering**: Fields displayed as-is from CSV, empty fields hidden
+
+**Why utility permits:**
+Utility companies often must file permits when installing surveillance infrastructure. This creates a paper trail that can indicate potential surveillance sites before devices are confirmed through direct observation.
+
+### 10. Upload Mode Simplification
+
+**Release vs Debug builds:**
+- **Release builds**: Production OSM only (simplified UX)
+- **Debug builds**: Full sandbox/simulate options available
+Most users should contribute to production; testing modes add complexity
+
+**Implementation:**
+```dart
+// Upload mode selection disabled in release builds
+bool get showUploadModeSelector => kDebugMode;
+```
+
+### 11. Navigation & Routing (Implemented, Awaiting Integration)
+
+**Current state:**
+- **Search functionality**: Fully implemented and active
+- **Basic routing**: Complete but disabled pending API integration
+- **Avoidance routing**: Awaiting alprwatch.org/directions API
+- **Offline routing**: Requires vector map tiles
+
+**Architecture:**
+- NavigationState manages routing computation and turn-by-turn instructions
+- RoutingService handles API communication and route calculation
+- SearchService provides location lookup and geocoding

 - **Battery life**: Excessive network requests drain battery
 - **Clear feedback**: Users understand why nodes aren't showing
 
+### 6. Why Separate Compass Indicator from Follow Mode?
+
+**Alternative**: Combined "follow with north up" mode
+
+**Why separate controls:**
+- **Clear user mental model**: "Follow me" vs "lock to north" are distinct concepts
+- **Flexible combinations**: Users can follow without north lock, or vice versa
+- **Avoid mode conflicts**: Follow+rotate is incompatible with north lock
+- **Reduced confusion**: Previous "north up" mode didn't actually keep north up
+
+**Design benefits:**
+- **Brutalist approach**: Two simple, independent features instead of complex mode combinations
+- **Visual feedback**: Compass shows exact map orientation regardless of follow state
+- **Smart gesture detection**: Differentiates intentional rotation from zoom artifacts
+- **Predictable behavior**: Each control does exactly what it says

+## Release Process & GitHub Actions
+
+The app uses a **clean, release-triggered workflow** that rebuilds from scratch for maximum reliability:
+
+### How It Works
+
+**Trigger: GitHub Release Creation**
+- Create a GitHub release → Workflow automatically builds, attaches assets, and optionally uploads to stores
+- **Pre-release checkbox** controls store uploads:
+  - ✅ **Checked** → Build + attach assets (no store uploads)
+  - ✅ **Unchecked** → Build + attach assets + upload to App/Play stores
+
+### Release Types
+
+**Development/Beta Releases**
+1. Create GitHub release from any tag/branch
+2. ✅ **Check "pre-release"** checkbox
+3. Publish → Assets built and attached, no store uploads
+
+**Production Releases**  
+1. Create GitHub release from main/stable branch
+2. ❌ **Leave "pre-release" unchecked**
+3. Publish → Assets built and attached + uploaded to stores
+
+### Store Upload Destinations
+
+**Google Play Store:**
+- Uploads to **Internal Testing** track
+- Requires manual promotion to Beta/Production
+- You maintain full control over public release
+
+**App Store Connect:**
+- Uploads to **TestFlight**  
+- Requires manual App Store submission
+- You maintain full control over public release
+
+### Required Secrets
+
+**For Google Play Store Upload:**
+- `GOOGLE_PLAY_SERVICE_ACCOUNT_JSON` - Complete JSON service account key (plain text)
+
+**For iOS App Store Upload:**
+- `APP_STORE_CONNECT_API_KEY_ID` - App Store Connect API key ID
+- `APP_STORE_CONNECT_ISSUER_ID` - App Store Connect issuer ID  
+- `APP_STORE_CONNECT_API_KEY_BASE64` - Base64-encoded .p8 API key file
+
+**For Building:**
+- `OSM_PROD_CLIENTID` - OpenStreetMap production OAuth2 client ID
+- `OSM_SANDBOX_CLIENTID` - OpenStreetMap sandbox OAuth2 client ID
+- Android signing secrets (keystore, passwords, etc.)
+- iOS signing certificates and provisioning profiles
+
+### Google Play Store Setup
+
+1. **Google Cloud Console:**
+   - Create Service Account with "Project Editor" role
+   - Enable Google Play Android Developer API
+   - Download JSON key file
+
+2. **Google Play Console:**
+   - Add service account email to Users & Permissions
+   - Grant "Release Manager" permissions for your app
+   - Complete first manual release to activate app listing
+
+3. **GitHub Secrets:**
+   - Store entire JSON key as `GOOGLE_PLAY_SERVICE_ACCOUNT_JSON` (plain text)
+
+### Workflow Benefits
+
+✅ **Brutalist simplicity** - One trigger, clear behavior  
+✅ **No external dependencies** - Only uses trusted `r0adkll/upload-google-play@v1`  
+✅ **Explicit control** - GitHub's UI checkbox controls store uploads  
+✅ **Always rebuilds** - No stale artifacts or cross-workflow complexity  
+✅ **Safe defaults** - Pre-release prevents accidental production uploads  
+✅ **No tag coordination** - Works with any commit, tag, or branch
