+# Developer Documentation
+
+This document provides detailed technical information about the DeFlock app architecture, key design decisions, and development guidelines.
+
+---
+
+## Philosophy: Brutalist Code
+
+Our development approach prioritizes **simplicity over cleverness**:
+
+- **Explicit over implicit**: Clear, readable code that states its intent
+- **Few edge cases by design**: Avoid complex branching and special cases
+- **Maintainable over efficient**: Choose the approach that's easier to understand and modify
+- **Delete before adding**: Remove complexity when possible rather than adding features
+
+**Hierarchy of preferred code:**
+1. **Code we don't write** (through thoughtful design and removing edge cases)
+2. **Code we can remove** (by seeing problems from a new angle)
+3. **Code that sadly must exist** (simple, explicit, maintainable)
+
+---
+
+## Architecture Overview
+
+### State Management
+
+The app uses **Provider pattern** with modular state classes:
+
+```
+AppState (main coordinator)
+├── AuthState (OAuth2 login/logout)
+├── OperatorProfileState (operator tag sets)
+├── ProfileState (node profiles & toggles)
+├── SessionState (add/edit sessions)
+├── SettingsState (preferences & tile providers)
+├── UploadQueueState (pending operations)
+├── SuspectedLocationState (permit data & display)
+├── NavigationState (routing & search)
+└── SearchState (location search results)
+```
+
+**Why this approach:**
+- **Separation of concerns**: Each state handles one domain
+- **Testability**: Individual state classes can be unit tested
+- **Brutalist**: No complex state orchestration, just simple delegation
+
+### Data Flow Architecture
+
+```
+UI Layer (Widgets)
+    ↕️
+AppState (Coordinator) 
+    ↕️
+State Modules (AuthState, ProfileState, etc.)
+    ↕️
+Services (MapDataProvider, NodeCache, Uploader)
+    ↕️
+External APIs (OSM, Overpass, Tile providers)
+```
+
+**Key principles:**
+- **Unidirectional data flow**: UI → AppState → Services → APIs
+- **No direct service access from UI**: Everything goes through AppState
+- **Clean boundaries**: Each layer has a clear responsibility
+
+---
+
+## 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
+- **SubmissionGuideDialog**: One-time popup before first node submission with best practices
+- **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
+- **Location Permission**: Requested immediately after welcome dialog on first launch (v2.6.3+)
+- **First Submission**: Submission guide popup with best practices and resource links
+- **Version Updates**: Changelog popup (only if content exists, no "don't show again")  
+- **Settings Access**: Complete changelog history available in Settings > About > Release Notes
+
+### Permission Handling (Updated v2.6.3)
+- **Location Permission**: Requested on first launch for core GPS functionality
+- **Notification Permission**: Requested on-demand when user enables proximity alerts
+
+### 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 & Smart Area Caching
+
+**Purpose**: Unified interface for fetching map tiles and surveillance nodes with intelligent area caching
+
+**Design decisions:**
+- **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()`: Returns cache immediately, triggers pre-fetch if needed (spatial or temporal)
+- `getTile()`: Tile fetching with unlimited retry strategy (retries until success)
+- `_fetchRemoteNodes()`: Handles Overpass → OSM API fallback
+
+**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/Extract)
+
+**Upload Operations Enum:**
+```dart
+enum UploadOperation { create, modify, delete, extract }
+```
+
+**Why explicit enum vs boolean flags:**
+- **Brutalist**: Four explicit states instead of nullable booleans
+- **Extensible**: Easy to add new operations (like bulk operations)
+- **Clear intent**: `operation == UploadOperation.delete` is unambiguous
+
+**Operations explained:**
+- **create**: Add new node to OSM
+- **modify**: Update existing node's tags/position/direction
+- **delete**: Remove existing node from OSM
+- **extract**: Create new node with tags copied from constrained node, leaving original unchanged
+
+**Session Pattern:**
+- `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.
+
+### 3. Upload Queue System & Three-Stage Upload Process
+
+**Design principles:**
+- **Three explicit stages**: Create changeset → Upload node → Close changeset
+- **Operation-agnostic**: Same queue handles create/modify/delete/extract
+- **Offline-capable**: Queue persists between app sessions  
+- **Visual feedback**: Each operation type and stage has distinct UI state
+- **Stage-specific error recovery**: Appropriate retry logic for each of the 3 stages
+
+**Three-stage upload workflow:**
+1. **Stage 1 - Create Changeset**: Generate changeset XML and create on OSM
+   - Retries: Up to 3 attempts with 20s delays
+   - Failures: Reset to pending for full retry
+2. **Stage 2 - Node Operation**: Create/modify/delete the surveillance node
+   - Retries: Up to 3 attempts with 20s delays  
+   - Failures: Close orphaned changeset, then retry from stage 1
+3. **Stage 3 - Close Changeset**: Close the changeset to finalize
+   - Retries: Exponential backoff up to 59 minutes
+   - Failures: OSM auto-closes after 60 minutes, so we eventually give up
+
+**Queue processing workflow (v2.3.0+ concurrent processing):**
+1. User action (add/edit/delete) → `PendingUpload` created with `UploadState.pending`
+2. Immediate visual feedback (cache updated with temp markers)
+3. Background uploader starts new uploads every 5 seconds (configurable via `kUploadQueueProcessingInterval`):
+   - **Concurrency limit**: Maximum 5 uploads processing simultaneously (`kMaxConcurrentUploads`)
+   - **Individual lifecycles**: Each upload processes through all three stages independently
+   - **Timer role**: Only used to start new pending uploads, not control stage progression
+4. Each upload processes through stages without waiting for other uploads:
+   - **Pending** → Create changeset → **CreatingChangeset** → **Uploading**
+   - **Uploading** → Upload node → **ClosingChangeset** 
+   - **ClosingChangeset** → Close changeset → **Complete**
+5. Success → cache updated with real data, temp markers removed
+6. Failures → appropriate retry logic based on which stage failed
+
+**Performance improvement (v2.3.0):**
+- **Before**: Sequential processing with 10-second delays between each stage of each upload
+- **After**: Concurrent processing with uploads completing in 10-30 seconds regardless of queue size
+- **User benefit**: 3-5x faster upload processing for users with good internet connections
+
+**Why three explicit stages:**
+The previous implementation conflated changeset creation + node operation as one step, making error handling unclear. The new approach:
+- **Tracks which stage failed**: Users see exactly what went wrong
+- **Handles step 2 failures correctly**: Node operation failures now properly close orphaned changesets  
+- **Provides clear UI feedback**: "Creating changeset...", "Uploading...", "Closing changeset..."
+- **Enables appropriate retry logic**: Different stages have different retry needs
+
+**Stage-specific error handling:**
+- **Stage 1 failure**: Simple retry (no cleanup needed)
+- **Stage 2 failure**: Close orphaned changeset, then retry from stage 1
+- **Stage 3 failure**: Keep retrying with exponential backoff (most important for OSM data integrity)
+
+**Why immediate visual feedback:**
+Users expect instant response to their actions. By immediately updating the cache with temporary markers (e.g., `_pending_deletion`), the UI stays responsive while the actual API calls happen in background.
+
+**Queue persistence & cache synchronization (v1.5.4+):**
+- **Startup repopulation**: Queue initialization now repopulates cache with pending nodes, ensuring visual continuity after app restarts
+- **Specific node cleanup**: Each upload stores a `tempNodeId` for precise removal, preventing accidental cleanup of other pending nodes at the same location
+- **Proximity awareness**: Proximity warnings now consider pending nodes to prevent duplicate submissions at the same location
+- **Processing status UI**: Upload queue screen shows clear indicators when processing is paused due to offline mode or user settings
+
+### 4. Cache & Visual States
+
+**Node visual states:**
+- **Blue ring**: Real nodes from OSM
+- **Purple ring**: Pending uploads (new nodes)
+- **Grey ring**: Original nodes with pending edits
+- **Orange ring**: Node currently being edited
+- **Red ring**: Nodes pending deletion
+
+**Node dimming behavior:**
+- **Dimmed (50% opacity)**: Non-selected nodes when a specific node is selected for tag viewing, or all nodes during search/navigation modes
+- **Selection persistence**: When viewing a node's tag sheet, other nodes remain dimmed even when the map is moved, until the sheet is closed (v2.1.3+ fix)
+
+**Direction cone visual states:**
+- **Full opacity**: Active session direction (currently being edited)
+- **Reduced opacity (40%)**: Inactive session directions
+- **Standard opacity**: Existing node directions (when not in edit mode)
+
+**Cache tags for state tracking:**
+```dart
+'_pending_upload'    // New node waiting to upload
+'_pending_edit'      // Original node has pending edits
+'_pending_deletion'  // Node queued for deletion
+'_original_node_id'  // For drawing connection lines
+```
+
+**Multi-direction parsing:**
+The app supports nodes with multiple directions specified as semicolon-separated values:
+```dart
+// OSM tag: direction="90;180;270"
+List<double> get directionDeg {
+  final raw = tags['direction'] ?? tags['camera:direction'];
+  // Splits on semicolons, parses each direction, normalizes to 0-359°
+  return [90.0, 180.0, 270.0]; // Results in multiple FOV cones
+}
+```
+
+**Why underscore prefix:**
+These are internal app tags, not OSM tags. The underscore prefix makes this explicit and prevents accidental upload to OSM.
+
+### 5. Enhanced Overpass Integration & Error Handling
+
+**Production mode:** Overpass API → OSM API fallback
+**Sandbox mode:** OSM API only (Overpass doesn't have sandbox data)
+
+**Zoom level restrictions:**
+- **Production (Overpass)**: Zoom ≥ 10 (established limit)
+- **Sandbox (OSM API)**: Zoom ≥ 13 (stricter due to bbox limits)
+
+**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 & deduplication:**
+- **Pre-fetch limit**: 4x user's display limit (e.g., 1000 nodes for 250 display limit)
+- **Profile deduplication**: Automatically removes redundant profiles from queries using subsumption analysis
+- **User-initiated detection**: Only reports loading status for user-facing operations  
+- **Background operations**: Pre-fetch runs silently, doesn't trigger loading states
+
+**Profile subsumption optimization (v2.1.1+):**
+To reduce Overpass query complexity, profiles are deduplicated before query generation:
+- **Subsumption rule**: Profile A subsumes profile B if all of A's non-empty tags exist in B with identical values
+- **Example**: `Generic ALPR` (tags: `man_made=surveillance, surveillance:type=ALPR`) subsumes `Flock` (same tags + `manufacturer=Flock Safety`)
+- **Result**: Default profile set reduces from ~11 to ~2 query clauses (Generic ALPR + Generic Gunshot)
+- **UI unchanged**: All enabled profiles still used for post-query filtering and display matching
+
+**Why this approach:**
+Dense urban areas (SF, NYC) with many profiles enabled can easily exceed both 50k node limits and 25s timeouts. Profile deduplication reduces query complexity by ~80% for default setups, while automatic splitting handles remaining edge cases. Surgical error detection avoids unnecessary API load from network issues.
+
+### 6. Uploader Service Architecture (Refactored v1.5.3)
+
+**Three-method approach:**
+The `Uploader` class now provides three distinct methods matching the OSM API workflow:
+
+```dart
+// Step 1: Create changeset
+Future<UploadResult> createChangeset(PendingUpload p) async
+
+// Step 2: Perform node operation (create/modify/delete/extract) 
+Future<UploadResult> performNodeOperation(PendingUpload p, String changesetId) async
+
+// Step 3: Close changeset
+Future<UploadResult> closeChangeset(String changesetId) async
+```
+
+**Simplified UploadResult:**
+Replaced complex boolean flags with simple success/failure:
+```dart
+UploadResult.success({changesetId, nodeId})  // Operation succeeded
+UploadResult.failure({errorMessage, ...})   // Operation failed with details
+```
+
+**Legacy compatibility:**
+The `upload()` method still exists for simulate mode and backwards compatibility, but now internally calls the three-step methods in sequence.
+
+**Why this architecture:**
+- **Brutalist simplicity**: Each method does exactly one thing
+- **Clear failure points**: No confusion about which step failed  
+- **Easier testing**: Each stage can be unit tested independently
+- **Better error messages**: Specific failure context for each stage
+
+### 7. Offline vs Online Mode Behavior
+
+**Mode combinations:**
+```
+Production + Online  → Local cache + Overpass API
+Production + Offline → Local cache only
+Sandbox + Online     → OSM API only (no cache mixing)
+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.
+
+### 8. 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
+- **On-demand permissions**: Notification permission requested only when user enables proximity alerts (v2.6.3+)
+
+**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
+- Permission requests deferred until feature activation for better UX
+
+### 9. Compass Indicator & North Lock
+
+**Purpose**: Visual compass showing map orientation with optional north-lock functionality
+
+**Design decisions:**
+- **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.
+
+### 10. Network Status Indicator (Refactored in v2.6.1)
+
+**Purpose**: Show loading and error states for surveillance data fetching only
+
+**Brutalist approach (v2.6.1+):**
+- **Single enum state**: Replaced multiple boolean flags with simple `NetworkRequestStatus` enum
+- **User-initiated only**: Only tracks latest user-initiated requests (pan/zoom), background requests ignored
+- **Auto-reset timers**: Different timeouts for different states (success: 2s, errors: 5s, rate limit: 2min)
+
+**Status states:**
+```dart
+enum NetworkRequestStatus {
+  idle,        // No indicator shown
+  loading,     // Initial request in progress
+  splitting,   // Request being split due to limits/timeouts
+  success,     // Data loaded successfully (brief confirmation)
+  timeout,     // Request timed out
+  rateLimited, // API rate limited
+  noData,      // No offline data available
+  error,       // Other network errors
+}
+```
+
+**State transitions:**
+- **Normal flow**: `idle` → `loading` → `success` → `idle`
+- **Split requests**: `loading` → `splitting` → `success` → `idle`
+- **Errors**: `loading` → `timeout/error/rateLimited` → `idle`
+
+**Why the refactor:**
+The previous system used multiple boolean flags with complex reconciliation logic, creating potential for conflicting states and race conditions. The new enum-based approach provides clear, explicit state management with predictable transitions and eliminates complexity while maintaining all functionality.
+
+**Request ownership:**
+Only user-initiated requests (pan, zoom, manual refresh) report status. Background requests (pre-fetch, cache warming) complete silently to avoid status indicator noise.
+
+### 11. Suspected Locations (v1.8.0+: SQLite Database Storage)
+
+**Data pipeline:**
+- **CSV ingestion**: Downloads utility permit data from alprwatch.org (100MB+ datasets)
+- **SQLite storage**: Batch insertion into database with geographic indexing (v1.8.0+)
+- **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
+
+**Storage architecture (v1.8.0+):**
+- **Database**: SQLite with spatial indexing for efficient geographic queries
+- **Hybrid caching**: Sync cache for immediate UI response + async database queries  
+- **Memory efficiency**: No longer loads entire dataset into memory
+- **Legacy migration**: Automatic migration from SharedPreferences to SQLite
+
+**Performance improvements:**
+- **Startup time**: Reduced from 5-15 seconds to <1 second
+- **Memory usage**: Reduced from 200-400MB to <10MB 
+- **Query time**: Reduced from 100-500ms to 10-50ms with indexed queries
+- **Progressive loading**: UI shows cached results immediately, updates with fresh data
+
+**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
+
+**Database schema:**
+```sql
+CREATE TABLE suspected_locations (
+  ticket_no TEXT PRIMARY KEY,
+  centroid_lat REAL NOT NULL,
+  centroid_lng REAL NOT NULL, 
+  bounds TEXT,
+  geo_json TEXT,
+  all_fields TEXT NOT NULL
+);
+CREATE INDEX idx_centroid ON suspected_locations (centroid_lat, centroid_lng);
+```
+
+**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.
+
+**Why SQLite migration:**
+The original SharedPreferences approach became untenable as the CSV dataset grew beyond 100MB, causing memory pressure and long startup times. SQLite provides efficient storage and querying while maintaining the simple, brutalist architecture the project follows.
+
+### 12. 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;
+```
+
+### 13. Tile Provider System & Clean Architecture (v1.5.2+)
+
+**Architecture (post-v1.5.2):**
+- **Custom TileProvider**: Clean Flutter Map integration using `DeflockTileProvider` 
+- **Direct MapDataProvider integration**: Tiles go through existing offline/online routing
+- **No HTTP interception**: Eliminated fake URLs and complex HTTP clients
+- **Simplified caching**: Single cache layer (FlutterMap's internal cache)
+
+**Key components:**
+- `DeflockTileProvider`: Custom Flutter Map TileProvider implementation
+- `DeflockTileImageProvider`: Handles tile fetching through MapDataProvider
+- Automatic offline/online routing: Uses `MapSource.auto` for each tile
+
+**Tile provider configuration:**
+- **Flexible URL templates**: Support multiple coordinate systems and load-balancing patterns
+- **Built-in providers**: Curated set of high-quality, reliable tile sources  
+- **Custom providers**: Users can add any tile service with full validation
+- **API key management**: Secure storage with per-provider API keys
+
+**Supported URL placeholders:**
+```
+{x}, {y}, {z}          - Standard TMS tile coordinates
+{quadkey}              - Bing Maps quadkey format (alternative to x/y/z)
+{0_3}                  - Subdomain 0-3 for load balancing  
+{1_4}                  - Subdomain 1-4 for providers using 1-based indexing
+{api_key}              - API key insertion point (optional)
+```
+
+**Built-in providers:**
+- **OpenStreetMap**: Standard street map tiles, no API key required
+- **Bing Maps**: High-quality satellite imagery using quadkey system, no API key required  
+- **Mapbox**: Satellite and street tiles, requires API key
+- **OpenTopoMap**: Topographic maps, no API key required
+
+**Why the architectural change:**
+The previous HTTP interception approach (`SimpleTileHttpClient` with fake URLs) fought against Flutter Map's architecture and created unnecessary complexity. The new `TileProvider` approach:
+- **Cleaner integration**: Works with Flutter Map's design instead of against it
+- **Smart cache routing**: Only checks offline cache when needed, eliminating expensive filesystem searches
+- **Better error handling**: Graceful fallbacks for missing tiles  
+- **Cross-platform performance**: Optimizations that work well on both iOS and Android
+
+**Tile Loading Performance Fix (v1.5.2):**
+The major performance issue was discovered to be double caching with expensive operations:
+1. **Problem**: Every tile request checked offline areas via filesystem I/O, even when no offline data existed
+2. **Solution**: Smart cache detection - only check offline cache when in offline mode OR when offline areas actually exist for the current provider
+3. **Result**: Dramatically improved tile loading from 0.5-5 tiles/sec back to ~70 tiles/sec for normal browsing
+
+**Cross-Platform Optimizations:**
+- **Request deduplication**: Prevents multiple simultaneous requests for identical tile coordinates
+- **Optimized retry timing**: Faster initial retry (150ms vs 200ms) with shorter backoff for quicker recovery
+- **Queue size limits**: Maximum 100 queued requests to prevent memory bloat
+- **Smart queue management**: Drops oldest requests when queue fills up
+- **Reduced concurrent connections**: 8 threads instead of 10 for better stability across platforms
+
+### 14. Navigation & Routing (Implemented and Active)
+
+**Current state:**
+- **Search functionality**: Fully implemented and active
+- **Avoidance routing**: Fully implemented and active
+- **Distance feedback**: Shows real-time distance when selecting second route point
+- **Long distance warnings**: Alerts users when routes may timeout (configurable threshold)
+- **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
+
+**Distance warning system (v1.7.0):**
+- **Real-time distance display**: Shows distance from first to second point during selection
+- **Configurable threshold**: `kNavigationDistanceWarningThreshold` in dev_config (default 30km)
+- **User feedback**: Warning message about potential timeouts for long routes
+- **Brutalist approach**: Simple distance calculation using existing `Distance()` utility
+
+---
+
+## Key Design Decisions & Rationales
+
+### 1. Why Provider Pattern?
+
+**Alternatives considered:**
+- BLoC: Too verbose for our needs
+- Riverpod: Added complexity without clear benefit
+- setState: Doesn't scale beyond single widgets
+
+**Why Provider won:**
+- **Familiar**: Most Flutter developers know Provider
+- **Simple**: Minimal boilerplate
+- **Flexible**: Easy to compose multiple providers
+- **Battle-tested**: Mature, stable library
+
+### 2. Why Separate State Classes?
+
+**Alternative**: Single monolithic AppState
+
+**Why modular state:**
+- **Single responsibility**: Each state class has one concern
+- **Testability**: Easier to unit test individual features
+- **Maintainability**: Changes to auth don't affect profile logic
+- **Team development**: Different developers can work on different states
+
+### 3. Why Upload Queue vs Direct API Calls?
+
+**Alternative**: Direct API calls from UI actions
+
+**Why queue approach:**
+- **Offline capability**: Actions work without internet
+- **User experience**: Instant feedback, no waiting for API calls
+- **Error recovery**: Failed uploads can be retried
+- **Batch processing**: Could optimize multiple operations
+- **Visual feedback**: Users can see pending operations
+
+### 4. Why Overpass + OSM API vs Just One?
+
+**Why not just Overpass:**
+- Overpass doesn't have sandbox data
+- Overpass can be unreliable/slow
+- OSM API is canonical source
+
+**Why not just OSM API:**
+- OSM API has strict bbox size limits
+- OSM API returns all data types (inefficient)
+- Overpass is optimized for surveillance device queries
+
+**Result**: Use the best tool for each situation
+
+### 5. Why Zoom Level Restrictions?
+
+**Alternative**: Always fetch, handle errors gracefully
+
+**Why restrictions:**
+- **Prevents API abuse**: Large bbox queries can overload servers
+- **User experience**: Fetching 10,000 nodes causes UI lag
+- **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
+
+---
+
+## Development Guidelines
+
+### 1. Adding New Features
+
+**Before writing code:**
+1. Can we solve this by removing existing code?
+2. Can we simplify the problem to avoid edge cases?
+3. Does this fit the existing patterns?
+
+**When adding new upload operations:**
+1. Add to `UploadOperation` enum
+2. Update `PendingUpload` serialization
+3. Add visual state (color, icon)
+4. Update uploader logic
+5. Add cache cleanup handling
+
+### 2. Testing Philosophy
+
+**Priority order:**
+1. **Integration tests**: Test complete user workflows
+2. **Widget tests**: Test UI components with mock data
+3. **Unit tests**: Test individual state classes
+
+**Why integration tests first:**
+The most important thing is that user workflows work end-to-end. Unit tests can pass while the app is broken from a user perspective.
+
+### 3. Error Handling
+
+**Principles:**
+- **Never crash the UI**: Always provide fallbacks
+- **Fail gracefully**: Empty list is better than exception
+- **User feedback**: Show meaningful error messages
+- **Logging**: Use debugPrint for troubleshooting
+
+**Example pattern:**
+```dart
+try {
+  final result = await riskyOperation();
+  return result;
+} catch (e) {
+  debugPrint('Operation failed: $e');
+  // Show user-friendly message
+  showSnackBar('Unable to load data. Please try again.');
+  return <EmptyResult>[];
+}
+```
+
+### 4. State Updates
+
+**Always notify listeners:**
+```dart
+void updateSomething() {
+  _something = newValue;
+  notifyListeners(); // Don't forget this!
+}
+```
+
+**Batch related updates:**
+```dart
+void updateMultipleThings() {
+  _thing1 = value1;
+  _thing2 = value2;
+  _thing3 = value3;
+  notifyListeners(); // Single notification for all changes
+}
+```
+
+---
+
+## 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

+✅ **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

+2. **Sandbox OSM**: https://master.apis.dev.openstreetmap.org/oauth2/applications
+
+**Configuration:**
+```bash
+cp lib/keys.dart.example lib/keys.dart
+# Edit keys.dart with your OAuth2 client IDs
+```
+
+### iOS Setup
+```bash
+cd ios && pod install
+```
+
+### Running
+```bash
+flutter pub get
+./gen_icons_splashes.sh
+flutter run --dart-define=OSM_PROD_CLIENT_ID=[your OAuth2 client ID]

+
+## Debugging Tips
+
+### Common Issues
+
+**Nodes not appearing:**
+- Check zoom level (≥10 production, ≥13 sandbox)
+- Check upload mode vs expected data source
+- Check network connectivity
+- Look for console errors
+
+**Upload failures:**
+- Verify OAuth2 credentials
+- Check upload mode matches login (production vs sandbox)
+- Ensure node has required tags
+- Check network connectivity
+
+**Cache issues:**
+- Clear app data to reset cache
+- Check if offline mode is affecting behavior
+- Verify upload mode switches clear cache
+
+### Debug Logging
+
+**Enable verbose logging:**
+```dart
+debugPrint('[ComponentName] Detailed message: $data');
+```
+
+**Key areas to log:**
+- Network requests and responses
+- Cache operations
+- State transitions
+- User actions
+
+### Performance
+
+**Monitor:**
+- Memory usage during large node fetches
+- UI responsiveness during background uploads
+- Battery usage during GPS tracking

 ## For Developers
 
-### Architecture Highlights
-- **Unified data provider**: All map tiles and surveillance device data route through `MapDataProvider` with pluggable remote/local sources
-- **Modular settings**: Each settings section is a separate widget for maintainability
-- **State management**: Provider pattern with clean separation of concerns
-- **Offline-first**: Network calls are optional; app functions fully offline with downloaded data and queues uploads until online
-
-### Build Setup
-**Prerequisites**: Flutter SDK, Xcode (iOS), Android Studio  
-**OAuth Setup**: Register apps at [openstreetmap.org/oauth2](https://www.openstreetmap.org/oauth2/applications) and [OSM Sandbox](https://master.apis.dev.openstreetmap.org/oauth2/applications) to get a client ID
+**See [DEVELOPER.md](DEVELOPER.md)** for comprehensive technical documentation including:
+- Architecture overview and design decisions
+- Development setup and build instructions  
+- Release process and GitHub Actions automation
+- Code organization and contribution guidelines
+- Debugging tips and troubleshooting
 
+**Quick setup:**
 ```shell
-# Basic setup
 flutter pub get
 cp lib/keys.dart.example lib/keys.dart
-# Add your OAuth2 client IDs to keys.dart
-
-# iOS additional setup
-cd ios && pod install
-
-# Run
-flutter run
+# Add OAuth2 client IDs, then: flutter run
 ```
 
+**Releases**: The app uses GitHub's release system for automated building and store uploads. Simply create a GitHub release and use the "pre-release" checkbox to control whether builds go to app stores - checked for beta releases, unchecked for production releases.

 ## Roadmap
 
-### v1 todo/bug List
-- Update offline area nodes while browsing?
-- Camera deletions
-- Optional custom icons for camera profiles
-- Upgrade device marker design (considering nullplate's svg)
+### Needed Bugfixes
+- Make submission guide scarier
+- Tile cache trimming? Does fluttermap handle?
+- Filter NSI suggestions based on what has already been typed in
+- NSI sometimes doesn't populate a dropdown, maybe always on the second tag added during an edit session?
+- Clean cache when nodes have been deleted by others
+
+### Current Development
+- Support check_date= tag, update on all edits, quick button to update that only
+- Support source= tag, default to survey, let user pick a different value
+- Add ability to downvote suspected locations which are old enough
+- Turn by turn navigation or at least swipe nav sheet up to see a list
+- Import/Export map providers
+- Update default profiles from the website on launch to capture changes
 
 ### Future Features & Wishlist
-- Jump to location by coordinates, address, or POI name
-- Route planning that avoids surveillance devices (alprwatch.com/directions)
-- Suspected locations toggle (alprwatch.com/flock/utilities)
-- Location-based notifications when approaching surveillance devices
-- Red/yellow ring for devices missing specific tag details
-- "Cache accumulating" offline area?
-- "Offline areas" as tile provider?
-- Custom device providers and OSM/Overpass alternatives
+- Tap direction slider to enter integer directly
+- Tap pending queue item to edit again before submitting
+- Optional reason message when deleting
+- Update offline area data while browsing?
+- Save named locations to more easily navigate to home or work
+- Offline navigation (pending vector map tiles)
+
+### Maybes
+- Icons/glyphs for profiles
+- "Universal Links" for better handling of profile import when app is not installed
+- Yellow ring for devices missing specific tag details
+- Android Auto / CarPlay
+- "Cache accumulating" offline area? Most recent / most viewed?
+- Grab the full latest database for each profile just like for suspected locations (instead of overpass)?
+- Custom data providers? (OSM/Overpass alternatives)
+- Offer options for extracting nodes which are attached to a way/relation?
+  - Auto extract (how?)
+  - Leave it alone (wrong answer unless user chooses intentionally)
+  - Manual cleanup (cognitive load for users)
+  - Delete the old one (also wrong answer unless user chooses intentionally)
+  - Give multiple of these options??
