+- **50k node limit**: Automatically splits query into 4 quadrants, recursively up to 3 levels deep. This is a deterministic result-set size limit, so shrinking the queried area is the correct fix.
+- **Timeout errors**: Treated as a plain retryable network error — no splitting. Timeouts usually indicate server load or an expensive query, not "too much area", so firing off more sub-requests would only add load to an already-struggling server.
+- **Rate limiting (HTTP 429)**: Extended backoff (30s), no splitting (would make it worse). Still surfaces the same "slow" status indicator as the node-limit-splitting case, so the user sees consistent feedback either way.
+- **Surgical detection**: Only splits on the actual 50k node limit, not timeouts or other 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

-To reduce Overpass query complexity, profiles are deduplicated before query generation:
+**Query optimization & deduplication (in `OverpassService._buildQuery`):**
+Profiles are deduplicated before query generation via subsumption analysis:
 - **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
+- **UI unchanged**: All enabled profiles still used for post-query filtering and display matching (see `NodeProviderWithCache._matchesAnyProfile`), independent of which clauses were sent to Overpass
+- **Safety fallback**: if dedup would remove every profile (e.g. all profiles have only empty tags), the original full list is used instead of sending an empty query
 
 **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.

 **Why separate from follow mode:**

+### 10. Network Status Indicator (Refactored in v2.6.1)
 
 **Purpose**: Show loading and error states for surveillance data fetching only
 
-**Simplified approach (v1.5.2+):**
-- **Surveillance data focus**: Only tracks node/camera data loading, not tile loading
-- **Visual feedback**: Tiles show their own loading progress naturally
-- **Reduced complexity**: Eliminated tile completion tracking and multiple issue types
+**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 types:**
-- **Loading**: Shows when fetching surveillance data from APIs
-- **Success**: Brief confirmation when data loads successfully  
-- **Timeout**: Network request timeouts
-- **Limit reached**: When node display limit is hit
-- **API issues**: Overpass/OSM API problems only
+**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
+}
+```
 
-**What was removed:**
-- Tile server issue tracking (tiles handle their own progress)
-- "Both" network issue type (only surveillance data matters)
-- Complex semaphore-based completion detection
-- Tile-related status messages and localizations
+**State transitions:**
+- **Normal flow**: `idle` → `loading` → `success` → `idle`
+- **Split requests**: `loading` → `splitting` → `success` → `idle`
+- **Errors**: `loading` → `timeout/error/rateLimited` → `idle`
 
-**Why the change:**
-The previous approach tracked both tile loading and surveillance data, creating redundancy since tiles already show loading progress visually on the map. Users don't need to be notified about tile loading issues when they can see tiles loading/failing directly. Focusing only on surveillance data makes the indicator more purposeful and less noisy.
+**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.

 ## Build & Development Setup
 
 ### Prerequisites
-- **Flutter SDK**: Latest stable version
-- **Xcode**: For iOS builds (macOS only)
-- **Android Studio**: For Android builds
-- **Git**: For version control
+
+**macOS** (required for iOS builds; Android-only contributors can use macOS or Linux):
+
+| Tool | Install | Notes |
+|------|---------|-------|
+| **Homebrew** | [brew.sh](https://brew.sh) | Package manager for macOS |
+| **Flutter SDK 3.35+** | `brew install --cask flutter` | Installs Flutter + Dart (3.35+ required for RadioGroup widget) |

 1. **Production OSM**: https://www.openstreetmap.org/oauth2/applications
 2. **Sandbox OSM**: https://master.apis.dev.openstreetmap.org/oauth2/applications
+3. **OAuth2 Application Permissions**
+   * Uncheck "Confidential application?"
+   * Read user preferences (read_prefs)
+   * Modify the map (write_api)
+   * Read, update status and delete user messages (consume_messages)
+4. **Redirect URIs**
+   * deflockapp://auth
 
-**Configuration:**
+For local builds, create `build_keys.conf` (gitignored):
 ```bash
-cp lib/keys.dart.example lib/keys.dart
-# Edit keys.dart with your OAuth2 client IDs
+cp build_keys.conf.example build_keys.conf
+# Edit build_keys.conf with your OAuth2 client IDs
 ```
 
-### iOS Setup
+You can also pass keys directly via `--dart-define`:
 ```bash
-cd ios && pod install
+flutter run --dart-define=OSM_PROD_CLIENTID=your_id --dart-define=OSM_SANDBOX_CLIENTID=your_id
 ```
 
+### First Build
+
+```bash
+# 1. Install dependencies
+flutter pub get
+
+# 2. Generate icons and splash screens (gitignored, must be regenerated)
+./gen_icons_splashes.sh
+
+# 3. Build Android
+flutter build apk --debug \
+  --dart-define=OSM_PROD_CLIENTID=your_id \
+  --dart-define=OSM_SANDBOX_CLIENTID=your_id
+
+# 4. Build iOS (macOS only, no signing needed for testing)
+flutter build ios --no-codesign \
+  --dart-define=OSM_PROD_CLIENTID=your_id \
+  --dart-define=OSM_SANDBOX_CLIENTID=your_id
+```
+
+> **Important:** You must run `./gen_icons_splashes.sh` before the first build. The generated icons and splash screen assets are gitignored, so the build will fail without this step.
+
 ### Running
+
 ```bash
-flutter pub get
-flutter run
+# Run on connected device or simulator
+flutter run --dart-define=OSM_PROD_CLIENTID=your_id --dart-define=OSM_SANDBOX_CLIENTID=your_id
+
+# Or use the build script (reads keys from build_keys.conf)
+./do_builds.sh              # Both platforms
+./do_builds.sh --android    # Android only
+./do_builds.sh --ios        # iOS only

 ## Roadmap
 
-### Needed Bugfixes
-- Add cancel button to submission guide
-- When not logged in, submit button should take users to settings>account to log in.
-- Ensure GPS/follow-me works after recent revamp (loses lock? have to move map for button state to update?)
-- Add new tags to top of a profile so they're visible immediately
-- Allow arbitrary entry on refine tags page
-- Don't show NSI suggestions that aren't sufficiently popular (image=)
-- Clean cache when nodes have been deleted by others
-- Are offline areas preferred for fast loading even when online? Check working.
-
-### Current Development
-- 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, profiles (profiles from deflock identify page?)
-
-### On Pause
-- Offline navigation (pending vector map tiles)
-
-### Future Features & Wishlist
-- Optional reason message when deleting
-- Update offline area data while browsing?
-
-### Maybes
-- Yellow ring for devices missing specific tag details
-- Android Auto / CarPlay
-- "Cache accumulating" offline area?
-- "Offline areas" as tile provider?
-- Grab the full latest database for each profile just like for suspected locations (instead of overpass)?
-- Optional custom icons for profiles to aid identification
-- Custom device providers and 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??
