Subject: [PATCH 01/16] feat: implement automatic relay synchronization with
 Mostro instances

Add relay sync system that auto-discovers relays from Mostro via kind 10002 events with user blacklist for permanent blocking. Users can remove relays from blacklist and manually re-add them anytime.

  - Real-time sync via Nostr subscriptions
  - User blacklist prevents unwanted relay re-addition
  - Smart re-enablement: manually adding removes from blacklist
  - Source tracking (user/mostro/default)
  - Backward compatible with existing configurations

+## Relay Synchronization System
+
+### Overview
+Comprehensive system that automatically synchronizes the app's relay list with the configured Mostro instance while providing users full control through an intelligent blacklist mechanism.
+
+### Core Components
+
+#### **RelayListEvent Model** (`lib/core/models/relay_list_event.dart`)
+- Parses NIP-65 (kind 10002) events from Mostro instances
+- Validates relay URLs (WebSocket only)
+- Robust handling of different timestamp formats
+- Null-safe parsing for malformed events
+
+#### **Enhanced Relay Model** (`lib/features/relays/relay.dart`)
+```dart
+enum RelaySource {
+  user,           // Manually added by user
+  mostro,         // Auto-discovered from Mostro
+  defaultConfig,  // App default relay
+}
+
+class Relay {
+  final RelaySource source;
+  bool get canDelete;      // User relays only
+  bool get canBlacklist;   // Mostro/default relays
+}
+```
+
+#### **Settings with Blacklist** (`lib/features/settings/settings.dart`)
+- New `blacklistedRelays: List<String>` field
+- Backward-compatible serialization
+- Automatic migration for existing users
+
+#### **RelaysNotifier** (`lib/features/relays/relays_notifier.dart`)
+- **`syncWithMostroInstance()`**: Manual sync trigger
+- **`removeRelayWithBlacklist(String url)`**: Smart removal with blacklisting
+- **`addRelayWithSmartValidation(...)`**: Auto-removes from blacklist when user manually adds
+- **`_handleMostroRelayListUpdate()`**: Filters blacklisted relays during sync
+
+### Synchronization Flow
+
+#### **Real-time Sync**
+1. **App Launch**: Automatic subscription to kind 10002 events from configured Mostro
+2. **Event Reception**: Parse relay list and filter against blacklist
+3. **State Update**: Merge new relays while preserving user relays
+4. **NostrService**: Automatic reconnection to updated relay list
+
+#### **Blacklist System**
+```
+User removes Mostro relay → Added to blacklist → Never re-added during sync
+User manually adds relay → Removed from blacklist → Works as user relay
+```
+
+### Key Features
+
+#### **User Experience**
+- **Transparent Operation**: Sync happens automatically in background
+- **Full User Control**: Can permanently block problematic Mostro relays
+- **Reversible Decisions**: Manual addition re-enables previously blocked relays
+- **Preserved Preferences**: User relays always maintained across syncs
+
+#### **Technical Robustness**
+- **Real-time Updates**: WebSocket subscriptions for instant sync
+- **Error Resilience**: Graceful fallbacks and comprehensive error handling
+- **Race Protection**: Prevents concurrent sync operations
+- **Logging**: Detailed logging for debugging and monitoring
+
+#### **API Methods**
+```dart
+// SettingsNotifier blacklist management
+Future<void> addToBlacklist(String relayUrl);
+Future<void> removeFromBlacklist(String relayUrl);
+bool isRelayBlacklisted(String relayUrl);
+
+// RelaysNotifier smart operations
+Future<void> removeRelayWithBlacklist(String url);
+Future<void> clearBlacklistAndResync();
+```
+
+### Implementation Notes
+- **Subscription Management**: Uses `SubscriptionManager` with dedicated relay list stream
+- **State Persistence**: Blacklist automatically saved to SharedPreferences
+- **Backward Compatibility**: Existing relay configurations preserved and migrated
+- **Testing**: Comprehensive unit tests in `test/features/relays/` (currently disabled due to complex mocking requirements)

Subject: [PATCH 06/16] feat: redesign relay screen with switch toggles

  - Modern switch-based UI with vertical alignment and consistent styling
  - Fix user relays disappearing on app restart via proper state preservation
  - Prevent blacklist contamination between different Mostro instances
  - Include user relays in NostrService operations alongside Mostro/default relays

 ### Relay Management System
 - **Automatic Sync**: Real-time synchronization with Mostro instance relay lists via kind 10002 events
-- **User Control**: Sophisticated blacklist system allowing permanent blocking of auto-discovered relays
-- **Smart Re-enablement**: Manual relay addition automatically removes from blacklist
-- **Source Tracking**: Relays tagged by source (user, mostro, default) for appropriate handling
+- **Dual Storage Strategy**: Mostro/default relays are stored in `settings.relays` and managed via blacklist system, while user relays are stored in `settings.userRelays` with full metadata preservation
+- **Differentiated Deletion**: Mostro/default relays when deactivated are added to blacklist and remain for potential re-activation, user relays when deleted are permanently removed from storage
+- **Source Tracking**: Relays tagged by source (user, mostro, default) for appropriate handling and storage strategy
+- **Smart Re-enablement**: Manual relay addition automatically removes from blacklist, Mostro relay re-activation removes from blacklist during sync
+- **URL Normalization**: All relay URLs are normalized by removing trailing slashes before blacklist comparison to ensure consistent matching regardless of input format
+- **Smart Validation**: Relay connectivity testing uses Nostr protocol validation (REQ/EVENT/EOSE cycle) with WebSocket fallback for unreachable relays
+- **Settings Persistence**: The Settings copyWith() method preserves existing selectedLanguage and defaultLightningAddress values when other fields are updated
 - **Implementation**: Located in `features/relays/` with core logic in `RelaysNotifier`

+#### 5. Relay Management System Architecture
+- **Dual Storage Implementation**: Mostro/default relays persist in `settings.relays` and use blacklist for deactivation, user relays persist in `settings.userRelays` with complete JSON metadata via `toJson()`/`fromJson()`
+- **Differentiated Lifecycle Management**: `removeRelayWithBlacklist()` adds Mostro/default relays to blacklist for potential restoration, `removeRelay()` permanently deletes user relays from both state and storage
+- **Storage Synchronization**: `_saveRelays()` method saves all active relays to `settings.relays` while separately preserving user relay metadata in `settings.userRelays`
+- **URL Normalization Process**: Relay URLs undergo normalization by trimming whitespace and removing trailing slashes using `_normalizeRelayUrl()` method throughout blacklist operations in `_handleMostroRelayListUpdate()`
+- **Settings Persistence Mechanism**: The Settings `copyWith()` method uses null-aware operators (`??`) to preserve existing values for selectedLanguage and defaultLightningAddress when not explicitly overridden
+- **Relay Validation Protocol**: Connectivity testing follows a two-tier approach: primary Nostr protocol test (sends REQ, waits for EVENT/EOSE) via `_testNostrProtocol()`, fallback WebSocket test via `_testBasicWebSocketConnectivity()`
+- **Blacklist Matching Logic**: All blacklist operations normalize both stored blacklist URLs and incoming relay URLs to ensure consistent string matching regardless of format variations

 ### Relay Management System
 - **Automatic Sync**: Real-time synchronization with Mostro instance relay lists via kind 10002 events
-- **Dual Storage Strategy**: Mostro/default relays are stored in `settings.relays` and managed via blacklist system, while user relays are stored in `settings.userRelays` with full metadata preservation
-- **Differentiated Deletion**: Mostro/default relays when deactivated are added to blacklist and remain for potential re-activation, user relays when deleted are permanently removed from storage
+- **Manual Addition**: Users can add custom relays with strict validation (wss://, domains only, connectivity required)
+- **Instance Validation**: Author pubkey checking prevents relay contamination between Mostro instances  
+- **Two-tier Testing**: Nostr protocol + WebSocket connectivity validation
+- **Memory Safety**: Isolated test instances protect main app connectivity during validation
+- **Dual Storage Strategy**: Mostro/default relays stored in `settings.relays`, user relays stored in `settings.userRelays` with full metadata preservation
 - **Source Tracking**: Relays tagged by source (user, mostro, default) for appropriate handling and storage strategy
 - **Smart Re-enablement**: Manual relay addition automatically removes from blacklist, Mostro relay re-activation removes from blacklist during sync
-- **URL Normalization**: All relay URLs are normalized by removing trailing slashes before blacklist comparison to ensure consistent matching regardless of input format
-- **Smart Validation**: Relay connectivity testing uses Nostr protocol validation (REQ/EVENT/EOSE cycle) with WebSocket fallback for unreachable relays
-- **Settings Persistence**: The Settings copyWith() method preserves existing selectedLanguage and defaultLightningAddress values when other fields are updated
+- **URL Normalization**: All relay URLs normalized by removing trailing slashes to ensure consistent matching
 - **Implementation**: Located in `features/relays/` with core logic in `RelaysNotifier`
 
+#### Manual Relay Addition
+- Users can manually add relays via `addRelayWithSmartValidation()` method
+- Five sequential validations: URL normalization, duplicate check, domain validation, connectivity testing, blacklist management  
+- Security requirements: Only wss:// protocol, domain-only (no IP addresses), mandatory connectivity test
+- Smart URL handling: Auto-adds "wss://" prefix if missing
+- Source tracking: Manual relays marked as `RelaySource.user`
+- Blacklist override: Manual addition automatically removes relay from blacklist
+
+#### Dual Storage Architecture
+- **Active Storage**: `settings.relays` contains active relay list used by NostrService
+- **Metadata Storage**: `settings.userRelays` preserves complete JSON metadata for user relays
+- **Lifecycle Management**: `removeRelayWithBlacklist()` adds Mostro/default relays to blacklist, `removeRelay()` permanently deletes user relays
+- **Storage Synchronization**: `_saveRelays()` method synchronizes both storage locations
+
+#### Instance Isolation
+- Author pubkey validation prevents relay contamination between different Mostro instances
+- Subscription cleanup on instance switching via `unsubscribeFromMostroRelayList()`
+- State cleanup removes old Mostro relays when switching instances via `_cleanMostroRelaysFromState()`
+
+#### Relay Validation System  
+- Two-tier connectivity testing: Primary Nostr protocol test (REQ/EVENT/EOSE), WebSocket fallback
+- Domain-only policy: IP addresses completely rejected
+- URL normalization: Trailing slash removal prevents duplicate entries
+- Instance-isolated testing: Test connections don't affect main app connectivity
+
+## App Initialization Process
+
+### Initialization Sequence
+The app follows a specific initialization order in `appInitializerProvider`:
+
+1. **NostrService Initialization**: Establishes WebSocket connections to configured relays
+2. **KeyManager Initialization**: Loads cryptographic keys from secure storage  
+3. **SessionNotifier Initialization**: Loads active trading sessions from Sembast database
+4. **SubscriptionManager Creation**: Registers session listeners with `fireImmediately: false`
+5. **Background Services Setup**: Configures notification and sync services
+6. **Order Notifier Initialization**: Creates individual order managers for active sessions
+
+### Critical Timing Requirements
+- SessionNotifier must complete initialization before SubscriptionManager setup
+- SubscriptionManager uses `fireImmediately: false` to prevent premature execution
+- Proper sequence ensures orders appear consistently in UI across app restarts

 ### Mock Files Guidelines  
 - **Generated file**: `test/mocks.mocks.dart` is auto-generated by Mockito
-- **File-level ignores**: Already contains `// ignore_for_file: must_be_immutable` at top
-- **DO NOT add**: Individual `// ignore: must_be_immutable` comments to classes
-- **Common issue**: Adding individual ignores causes `duplicate_ignore` analyzer warnings
-- **MockSharedPreferencesAsync**: Specifically covered by existing file-level ignore
-- **Regeneration**: Use `dart run build_runner build -d` to update mocks
+- **File-level ignores**: Contains comprehensive ignore directives at file level
+- **Regeneration**: Use `dart run build_runner build -d` to update mocks after changes
+- **No manual editing**: Never manually modify generated mock files
