+
+## Completer 패턴 (필수)
+
+광고 완료를 기다리려면 Completer 사용:
+
+```dart
+Future<bool> showInterstitialAd(BuildContext context) async {
+  final completer = Completer<bool>();
+
+  ad.fullScreenContentCallback = FullScreenContentCallback(
+    onAdDismissedFullScreenContent: (ad) {
+      ad.dispose();
+      completer.complete(true);
+    },

+      completer.complete(false);
+    },
+  );
+
+  ad.show();
+  return completer.future;
+}
+```
+
+## "App not in foreground" 해결
+
+광고 로드 중 앱이 백그라운드로 가면 오류 발생.
+
+**해결책: 로딩 오버레이**
+
+```dart
+// 광고 로드 전 다이얼로그 표시 → 앱이 foreground 유지
+final closeLoading = _showLoadingOverlay(context);
+await _enterImmersiveMode();
+final loaded = await _ensureAdLoaded();
+closeLoading();
+```
+
+## 몰입형 모드
+
+```dart
+await SystemChrome.setEnabledSystemUIMode(
+  SystemUiMode.immersiveSticky,
+  overlays: [],
+);
+```
+
+## 흐름도
+
+```
+startScan()
+    ↓
+showLoadingOverlay() ← 앱 foreground 유지

-Before starting any task, you MUST respond in the following format:
+**버전**: 1.0.1+3
 
-```
-[Model Name]. I have reviewed all the following rules: [rule file list or categories]. Proceeding with the task. Master!
+## Quick Commands
+
+```bash
+# Hive 모델 생성
+dart run build_runner build --delete-conflicting-outputs
+
+# 빌드
+flutter build apk --release           # APK
+flutter build appbundle --release     # AAB (Play Store)
+
+# 버전업 후 디바이스 설치
+flutter install --release
 ```
 
-**Examples:**
+## Architecture
 
-- `Claude Sonnet 4. I have reviewed all the following rules: development guidelines, class structure, testing rules. Proceeding with the task. Master!`
-- For extensive rules: `coding style, class design, exception handling, testing rules` (categorized summary)
-
-## 🚀 Mandatory 3-Phase Task Process
-
-### Phase 1: Codebase Exploration & Analysis
-
-**Required Actions:**
-
-- Systematically discover ALL relevant files, directories, modules
-- Search for related keywords, functions, classes, patterns
-- Thoroughly examine each identified file
-- Document coding conventions and style guidelines
-- Identify framework/library usage patterns
-
-### Phase 2: Implementation Planning
-
-**Required Actions:**
-
-- Create detailed implementation roadmap based on Phase 1 findings
-- Define specific task lists and acceptance criteria per module
-- Specify performance/quality requirements
-
-### Phase 3: Implementation Execution
-
-**Required Actions:**
-
-- Implement each module following Phase 2 plan
-- Verify ALL acceptance criteria before proceeding
-- Ensure adherence to conventions identified in Phase 1
-
-## ✅ Core Development Principles
-
-### Language & Type Rules
-
-- **Write ALL code, variables, and names in English**
-- **Write ALL comments, documentation, prompts, and responses in Korean**
-- **Always declare types explicitly** for variables, parameters, and return values
-- Avoid `any`, `dynamic`, or loosely typed declarations (except when strictly necessary)
-- Define **custom types** when needed
-- Extract magic numbers and literals into named constants or enums
-
-### Naming Conventions
-
-|Element|Style|Example|
-|---|---|---|
-|Classes|`PascalCase`|`UserService`, `DataRepository`|
-|Variables/Methods|`camelCase`|`userName`, `calculateTotal`|
-|Files/Folders|`under_score_case`|`user_service.dart`, `data_models/`|
-|Environment Variables|`UPPERCASE`|`API_URL`, `DATABASE_PASSWORD`|
-
-**Critical Rules:**
-
-- **Boolean variables must be verb-based**: `isReady`, `hasError`, `canDelete`
-- **Function/method names start with verbs**: `executeLogin`, `saveUser`
-- Use meaningful, descriptive names
-- Avoid abbreviations unless widely accepted: `i`, `j`, `err`, `ctx`, `API`, `URL`
-
-## 🔧 Function & Method Design
-
-### Function Structure Principles
-
-- **Keep functions short and focused** (≤20 lines recommended)
-- **Avoid blank lines inside functions**
-- **Follow Single Responsibility Principle**
-- **Use verb + object format** for naming:
-    - Boolean return: `isValid`, `canRetry`, `hasPermission`
-    - Void return: `executeLogin`, `saveUser`, `startAnimation`
-
-### Function Optimization Techniques
-
-- Use **early returns** to avoid nested logic
-- Extract logic into helper functions
-- Prefer **arrow functions** for short expressions (≤3 lines)
-- Use **named functions** for complex logic
-- Minimize null checks by using **default values**
-- Minimize parameters using **RO-RO pattern** (Receive Object – Return Object)
-
-## 📦 Data & Class Design
-
-### Class Design Principles
-
-- **Strictly follow Single Responsibility Principle (SRP)**
-- **Favor composition over inheritance**
-- **Define interfaces/abstract classes** to establish contracts
-- **Prefer immutable data structures** (use `readonly`, `const`)
-
-### File Size Management
-
-- **Split by responsibility when exceeding 200 lines** (responsibility-based, not line-based)
-- ✅ **May remain as-is if**:
-    - Has **single clear responsibility**
-    - Is **easy to maintain**
-- 🔁 **Must split when**:
-    - Contains **multiple concerns**
-    - Requires **excessive scrolling**
-    - Patterns repeat across files
-    - Difficult for new developer onboarding
-
-### Class Recommendations
-
-- ≤ 200 lines (not mandatory)
-- ≤ 10 public methods
-- ≤ 10 properties
-
-### Data Model Design
-
-- Avoid excessive use of primitives — use **composite types or classes**
-- Move **validation logic inside data models** (not in business logic)
-
-## ❗ Exception Handling
-
-### Exception Usage Principles
-
-- Use exceptions only for **truly unexpected or critical issues**
-- **Catch exceptions only to**:
-    - Handle known failure scenarios
-    - Add useful context
-- Otherwise, let global handlers manage them
-
-## 🧪 Testing
-
-### Test Structure
-
-- Follow **Arrange–Act–Assert** pattern
-- Clear test variable naming: `inputX`, `mockX`, `actualX`, `expectedX`
-- **Write unit tests for every public method**
-
-### Test Doubles Usage
-
-- Use **test doubles** (mock/fake/stub) for dependencies
-- Exception: allow real use of **lightweight third-party libraries**
-
-### Integration Testing
-
-- Write **integration tests per module**
-- Follow **Given–When–Then** structure
-- Ensure **100% test pass rate in CI** and **apply immediate fixes** for failures
-
-## 📝 Git Commit Guidelines
-
-### Commit Message Format
-
-- **Use clear, descriptive commit messages in Korean**
-- **Follow conventional commit format**: `type: description`
-- **Keep commit messages concise and focused**
-- **DO NOT include Claude Code attribution or co-author tags**

-❌ **Avoid These:**
-- Including "🤖 Generated with [Claude Code](https://claude.ai/code)"
-- Including "Co-Authored-By: Claude <noreply@anthropic.com>"
-- Vague messages like "update code" or "fix stuff"
-- English commit messages (use Korean)
+## Project Rules
 
-### Critical Rules
+1. **로컬 전용**: 서버/Firebase/외부 DB 금지
+2. **권한 거부 시**: 수동 입력 폴백 (SMS), 기능 비활성화 (알림)
+3. **외부 API**: Clearbit Logo API만 허용
+4. **Isolate 주의**: `compute()` 내부에서 Flutter 바인딩/Context 접근 불가
 
-- **NEVER include AI tool attribution in commit messages**
-- **Focus on what was changed and why**
-- **Use present tense and imperative mood**
-- **Keep the first line under 50 characters when possible**
+## Known Patterns
 
-## 🧠 Error Analysis & Rule Documentation
+### 전면 광고 (AdService)
 
-### Mandatory Process When Errors Occur
-
-1. **Analyze root cause in detail**
-2. **Document preventive rule in `.cursor/rules/error_analysis.mdc`**
-3. **Write in English including**:
-    - Error description and context
-    - Cause and reproducibility steps
-    - Resolution approach
-    - Rule for preventing future recurrences
-    - Sample code and references to related rules
-
-### Rule Writing Standards
-
-```markdown
----
-description: Clear, one-line description of what the rule enforces
-globs: path/to/files/*.ext, other/path/**/*
-alwaysApply: boolean
----
-
-**Main Points in Bold**
-- Sub-points with details
-- Examples and explanations
+```dart
+// Completer 패턴으로 광고 완료 대기
+final completer = Completer<bool>();
+ad.fullScreenContentCallback = FullScreenContentCallback(
+  onAdDismissedFullScreenContent: (ad) {
+    completer.complete(true);
+  },
+);
+ad.show();
+return completer.future;
 ```
 
-## 🏗️ Architectural Guidelines
+### SMS 스캔 (Isolate)
 
-### Clean Architecture Compliance
+```dart
+// Isolate 내부에서는 하드코딩 사용
+// Flutter 바인딩, Context, Provider 접근 불가
+return 'Unknown service';  // AppLocalizations 사용 불가
+```
 
-- **Layered structure**: `modules`, `controllers`, `services`, `repositories`, `entities`
-- Apply **Repository Pattern** for data abstraction
-- Use **Dependency Injection** (`getIt`, `inject`, etc.)
-- Controllers handle business logic (not view processing)
+## Response Format
 
-### Code Structuring
-
-- **One export or public declaration per file**
-- Centralize constants, error messages, and configuration
-- Make **all shared logic reusable** and place in dedicated helper modules
-
-## 🌲 UI Structure & Component Design
-
-### UI Optimization Principles
-
-- **Avoid deeply nested widget/component trees**:
-    - Flatten hierarchy for **better performance and readability**
-    - Easier **state management and testability**
-- **Split large components into small, focused widgets/components**
-- Use `const` constructors (or equivalents) for performance optimization
-- Apply clear **naming and separation** between view, logic, and data layers
-
-## 📈 Continuous Rule Improvement
-
-### Rule Improvement Triggers
-
-- New code patterns not covered by existing rules
-- Repeated similar implementations across files
-- Common error patterns that could be prevented
-- New libraries or tools being used consistently
-- Emerging best practices in the codebase
-
-### Rule Update Criteria
-
-**Add New Rules When:**
-
-- A new technology/pattern is used in 3+ files
-- Common bugs could be prevented by a rule
-- Code reviews repeatedly mention the same feedback
-
-**Modify Existing Rules When:**
-
-- Better examples exist in the codebase
-- Additional edge cases are discovered
-- Related rules have been updated
-

+
+이 키스토어를 android/key.properties 등에서 참조하도록 설정하면 release 빌드를 실제 서명 키로 빌드할 수 있습니다. (예: storeFile=../doc/key/submanager-release.keystore, storePassword=submanager, keyAlias=submanager, keyPassword=submanager).
+
+이후 buildTypes.release에서 signingConfig = signingConfigs.getByName("release")로 연결하면 됩니다.
+
+android/key.properties을 새로 만들어 storeFile=../../doc/key/submanager-release.keystore 등 키 정보를 등록했습니다. (storePassword, keyPassword, keyAlias 모두 submanager로 설정)
+
+android/app/build.gradle.kts (lines 1-52)에 Properties/FileInputStream을 import하고 keystoreProperties 로드 후 signingConfigs.release를 추가했습니다. 이제 buildTypes.release가 디버그 키 대신 새 릴리스 키로 서명합니다.
+
+doc/key/submanager-release.keystore가 키스토어 위치이며, flutter build apk --release로 서명된 릴리스 APK(build/app/outputs/flutter-apk/app-release.apk)가 정상 생성되는 것을 확인했습니다.
+
+다음 단계로는 이 keystore와 key.properties를 안전한 곳에 보관하고, 필요 시 .gitignore 등으로 민감 파일이 VCS에 노출되지 않도록 관리하는 것을 권장합니다.
