+
+## [0.7.4] - 2025-11-25
+
+### Fixed
+
+- 🐛 **TypeScript-aware hardcode detection** - dramatically reduces false positives by 35.7%:
+  - Ignore strings in TypeScript union types (`type Status = 'active' | 'inactive'`)
+  - Ignore strings in interface property types (`interface { mode: 'development' | 'production' }`)
+  - Ignore strings in type assertions (`as 'read' | 'write'`)
+  - Ignore strings in typeof checks (`typeof x === 'string'`)
+  - Ignore strings in Symbol() calls for DI tokens (`Symbol('LOGGER')`)
+  - Ignore strings in dynamic import() calls (`import('../../module.js')`)
+  - Exclude tokens.ts/tokens.js files completely (DI container files)
+  - Tested on real-world TypeScript project: 985 → 633 issues (352 false positives eliminated)
+- ✅ **Added 13 new tests** for TypeScript type context filtering
+
+## [0.7.3] - 2025-11-25
+
+### Fixed
+
+- 🐛 **False positive: repository importing its own aggregate:**
+  - Added `isInternalBoundedContextImport()` method to detect internal imports
+  - Imports like `../aggregates/Entity` from `repositories/Repo` are now allowed
+  - This correctly allows `ICodeProjectRepository` to import `CodeProject` from the same bounded context
+  - Cross-aggregate imports (with multiple `../..`) are still detected as violations
+
+## [0.7.2] - 2025-11-25
+
+### Fixed
+
+- 🐛 **False positive: `errors` folder detected as aggregate:**
+  - Added `errors` and `exceptions` to `DDD_FOLDER_NAMES` constants
+  - Added to `nonAggregateFolderNames` — these folders are no longer detected as aggregates
+  - Added to `allowedFolderNames` — imports from `errors`/`exceptions` folders are allowed across aggregates
+  - Fixes issue where `domain/code-analysis/errors/` was incorrectly identified as a separate aggregate named "errors"
+
 ## [0.7.1] - 2025-11-25

+
+## 🔥 Guardian's Unique Advantages
+
+Guardian has **7 unique features** that no competitor offers:
+
+### 1. ✨ Hardcode Detection with AI Suggestions
+
+**Guardian:**
+```typescript
+// Detected:
+app.listen(3000)
+
+// Suggestion:
+💡 Extract to: DEFAULT_PORT
+📁 Location: infrastructure/config/constants.ts
+🤖 AI Prompt: "Extract port 3000 to DEFAULT_PORT constant in config"
+```
+
+**Competitors:**
+- SonarQube: Only detects hardcoded secrets (API keys), not magic numbers
+- Others: No hardcode detection at all
+
+### 2. 🔌 Framework Leak Detection
+
+**Guardian:**
+```typescript
+// domain/entities/User.ts
+import { Request } from 'express'  // ❌ VIOLATION!
+
+// Detected: Framework leak in domain layer
+// Suggestion: Use dependency injection via interfaces
+```
+
+**Competitors:**
+- ArchUnit: Can check via custom rules (not built-in)
+- Others: Not available
+
+### 3. 🎭 Entity Exposure Detection
+
+**Guardian:**
+```typescript
+// ❌ Bad: Domain entity exposed
+async getUser(): Promise<User> { }
+
+// ✅ Good: Use DTOs
+async getUser(): Promise<UserDto> { }
+
+// Guardian detects this automatically!
+```
+
+**Competitors:**
+- None have this built-in
+
+### 4. 📚 Repository Pattern Validation
+
+**Guardian:**
+```typescript
+// Detects ORM types in domain interfaces:
+interface IUserRepository {
+    findOne(query: { where: ... })  // ❌ Prisma-specific!
+}
+
+// Detects concrete repos in use cases:
+constructor(private prisma: PrismaClient) {}  // ❌ VIOLATION!
+```
+
+**Competitors:**
+- None validate repository pattern
+
+### 5. 🤖 AI-First Workflow
+
+**Guardian:**
+```bash
+# Generate AI-friendly fix prompt
+guardian check ./src --format ai-prompt > fix.txt
+
+# Feed to Claude/GPT:
+"Fix these Guardian violations: $(cat fix.txt)"
+
+# AI fixes → Run Guardian again → Ship it!
+```
+
+**Competitors:**
+- Generic output, not optimized for AI assistants
+
+### 6. 🛠️ Auto-Fix for Architecture (v0.9+)
+
+**Guardian:**
+```bash
+# Automatically extract hardcodes to constants
+guardian fix ./src --auto
+
+# Rename files to match conventions
+guardian fix naming ./src --auto
+
+# Interactive mode
+guardian fix ./src --interactive
+```
+
+**Competitors:**
+- ESLint has `--fix` but only for syntax
+- None fix architecture violations
+
+### 7. 🎯 DDD Pattern Detection (30+)
+
+**Guardian Roadmap:**
+- Aggregate boundaries
+- Anemic domain model
+- Domain events
+- Value Object immutability
+- CQRS violations
+- Saga pattern
+- Ubiquitous language
+- And 23+ more DDD patterns!
+
+**Competitors:**
+- Generic architecture checks only
+- No DDD-specific patterns

+```
+
+**Guardian:**
+```
+✅ Hardcode detected:
+   Type: magic-number
+   Value: 3000
+   💡 Suggested: DEFAULT_PORT
+   📁 Location: infrastructure/config/constants.ts
+   🤖 AI Fix: "Extract 3000 to DEFAULT_PORT constant"
+```
+
+---
+
+## vs dependency-cruiser
+
+### When dependency-cruiser Wins
+
+✅ **Visualization priority**
+```bash
+# Best-in-class dependency graphs
+depcruise src --output-type dot | dot -T svg > graph.svg
+```
+
+✅ **Custom dependency rules**
+```javascript
+// Highly flexible rule system
+forbidden: [

+    from: { path: '^src/domain' },
+    to: { path: '^src/infrastructure' }
+  }
+]
+```
+
+✅ **Multi-framework support**
+```
+JS, TS, Vue, Svelte, JSX, CoffeeScript
+```
+
+### When Guardian Wins
+
+✅ **DDD/Clean Architecture out-of-the-box**
+```typescript
+// Guardian knows these patterns:
+// - Domain/Application/Infrastructure layers
+// - Entity exposure
+// - Repository pattern
+// - Framework leaks
+
+// dependency-cruiser: Write custom rules for each
+```
+
+✅ **Hardcode detection**
+```typescript
+// Guardian finds:
+setTimeout(() => {}, 5000)  // Magic number
+const url = "http://..."    // Magic string
+
+// dependency-cruiser: Doesn't check this
+```
+
+✅ **AI workflow integration**
+```bash
+guardian check ./src --format ai-prompt
+# Optimized for Claude/GPT
+
+depcruise src
+# Generic output
+```
+
+### Complementary Usage
+
+**Best approach:** Use both!
+
+```bash
+# Guardian for architecture + hardcode
+guardian check ./src
+
+# dependency-cruiser for visualization
+depcruise src --output-type svg > architecture.svg
+```
+
+**Coming in Guardian v0.7.0:**
+```bash
+# Guardian will have built-in visualization!
+guardian visualize ./src --output architecture.svg
+```
+
+---
+
+## vs ArchUnit (Java)
+
+### When ArchUnit Wins
+
+✅ **Java projects**
+```java
+// ArchUnit is built for Java
+@ArchTest
+void domainShouldNotDependOnInfrastructure(JavaClasses classes) {
+    noClasses().that().resideInPackage("..domain..")
+        .should().dependOnClassesThat().resideInPackage("..infrastructure..")
+        .check(classes);
+}
+```
+
+✅ **Test-based architecture validation**
+```java
+// Architecture rules = unit tests
+// Runs in your CI with other tests
+```
+
+✅ **Mature Java ecosystem**
+```
+Spring Boot, Hibernate, JPA patterns
+Built-in rules for layered/onion architecture
+```
+
+### When Guardian Wins
+
+✅ **TypeScript/JavaScript projects**
+```typescript
+// Guardian is built for TypeScript
+// ArchUnit doesn't support TS
+```
+
+✅ **AI coding workflow**
+```bash
+# Guardian → AI → Fix → Ship
+# ArchUnit is test-based (slower feedback)
+```
+
+✅ **Zero-config DDD**
+```bash
+guardian check ./src
+# Works immediately with DDD structure
+
+# ArchUnit requires writing tests for each rule
+```
+
+### Philosophical Difference
+
+**ArchUnit:**
+```java
+// Architecture = Tests
+// You write explicit tests for each rule
+```
+
+**Guardian:**
+```bash
+# Architecture = Linter
+# Pre-configured DDD rules out-of-the-box
+```
+
+---
+
+## vs FTA (Fast TypeScript Analyzer)
+
+### When FTA Wins
+
+✅ **Complexity metrics focus**

+```
+FTA: 1600 files/second
+Guardian: ~500 files/second (Node.js)
+```
+
+✅ **Simplicity**
+```bash
+# FTA does one thing well: metrics
+fta src/
+```
+
+### When Guardian Wins
+
+✅ **Architecture enforcement**
+```typescript
+// Guardian checks:
+// - Layer violations
+// - Framework leaks
+// - Circular dependencies
+// - Repository pattern
+
+// FTA: Only measures complexity, no architecture checks
+```
+
+✅ **Hardcode detection**
+```typescript
+// Guardian finds magic numbers/strings
+// FTA doesn't check this
+```
+
+✅ **AI workflow**
+```bash
+# Guardian provides actionable suggestions
+# FTA provides metrics only
+```
+
+### Complementary Usage
+
+**Best approach:** Use both!
+
+```bash
+# Guardian for architecture
+guardian check ./src
+
+# FTA for complexity metrics
+fta src/ --threshold complexity:15
+```
+
+**Coming in Guardian v0.10.0:**
+```bash
+# Guardian will include complexity metrics!
+guardian metrics ./src --include-complexity
+```
+
+---
+
+## vs ESLint + Plugins
+
+### When ESLint Wins

+// ESLint doesn't understand:
+// - Clean Architecture layers
+// - DDD patterns
+// - Framework leaks
+// - Entity exposure
+
+// Guardian does!
+```
+
+✅ **Hardcode detection with context**
+```typescript
+// ESLint plugins check patterns
+// Guardian understands semantic context
+```
+
+✅ **AI workflow integration**
+```bash
+# Guardian optimized for AI assistants
+# ESLint generic output
+```
+
+### Complementary Usage
+
+**Best approach:** Use both!
+
+```bash
+# ESLint for code quality
+eslint src/
+
+# Guardian for architecture
+guardian check ./src
+```
+
+**Many teams run both in CI:**
+```yaml
+# .github/workflows/quality.yml
+- name: ESLint
+  run: npm run lint
+
+- name: Guardian
+  run: guardian check ./src --fail-on error
+```
+

+    myproject.application
+    myproject.infrastructure
+```
+
+✅ **Mature Python ecosystem**
+```python
+# Django, Flask, FastAPI integration
+```
+
+### When Guardian Wins
+
+✅ **TypeScript/JavaScript**

+```
+
+✅ **More than import checking**
+```typescript
+// Guardian checks:
+// - Hardcode
+// - Entity exposure
+// - Repository pattern
+// - Framework leaks
+
+// import-linter: Only imports
+```
+
+### Future Integration
+
+**Guardian v2.0+ (Planned):**
+```bash

+guardian check ./src
+
+# CI/CD: Run both
+# SonarQube (security) → Guardian (architecture)
+```
+
+### From ESLint-only to ESLint + Guardian
+
+**Why add Guardian:**
+```typescript
+// ESLint checks syntax
+// Guardian checks architecture
+```
+
+**How to add:**
+```bash
+# Keep ESLint
+npm run lint
+
+# Add Guardian
+guardian check ./src
+
+# Both in CI:
+npm run lint && guardian check ./src
+```
+
+### From dependency-cruiser to Guardian
+
+**Why migrate:**
+- Need more than circular deps
+- Want hardcode detection
+- Need DDD patterns
+- Want auto-fix (v0.9+)
+
+**How to migrate:**
+```bash
+# Replace:
+depcruise src --config .dependency-cruiser.js

+// ✅ GOOD: Use environment variables
+const AWS_KEY = process.env.AWS_ACCESS_KEY_ID
+const AWS_SECRET = process.env.AWS_SECRET_ACCESS_KEY
+const GITHUB_TOKEN = process.env.GITHUB_TOKEN
+```
+
+**Planned Features:**
+- ✅ **SecretDetector** - Standalone detector (separate from HardcodeDetector)
+- ✅ **Secretlint Integration** - Industry-standard library (@secretlint/node)
+- ✅ **350+ Secret Patterns** - AWS, GitHub, NPM, SSH, GCP, Slack, Basic Auth, etc.
+- ✅ **CRITICAL Severity** - All secret violations marked as critical
+- ✅ **Smart Suggestions** - Context-aware remediation per secret type
+- ✅ **Clean Architecture** - New ISecretDetector interface, SecretViolation value object
+- ✅ **CLI Integration** - New "🔐 Secrets" section in output
+- ✅ **Parallel Execution** - Runs alongside existing detectors
+
+**Secret Types Detected:**
+- AWS Access Keys & Secret Keys
+- GitHub Tokens (ghp_, github_pat_, gho_, etc.)
+- NPM tokens in .npmrc and code
+- SSH Private Keys
+- GCP Service Account credentials
+- Slack tokens (xoxb-, xoxp-, etc.)
+- Basic Auth credentials
+- JWT tokens
+- Private encryption keys
+
+**Architecture:**
+```typescript
+// New domain layer
+interface ISecretDetector {
+    detectAll(code: string, filePath: string): Promise<SecretViolation[]>
+}
+
+class SecretViolation {
+    file: string
+    line: number
+    secretType: string  // AWS, GitHub, NPM, etc.
+    message: string
+    severity: "critical"
+    suggestion: string  // Context-aware guidance
+}
+
+// New infrastructure implementation
+class SecretDetector implements ISecretDetector {
+    // Uses @secretlint/node internally
+}
+```
+
+**Why Secretlint?**
+- ✅ Actively maintained (updates weekly)
+- ✅ TypeScript native
+- ✅ Pluggable architecture
+- ✅ Low false positives
+- ✅ Industry standard
+
+**Why NOT custom implementation?**
+- ❌ No good npm library for magic numbers/strings
+- ❌ Our HardcodeDetector is better than existing solutions
+- ✅ Secretlint is perfect for secrets (don't reinvent the wheel)
+- ✅ Two focused detectors better than one bloated detector
+
+**Impact:**
+Guardian will now catch critical security issues BEFORE they reach production, complementing existing magic number/string detection.

+## 📅 Detailed Roadmap
+
+## Version 0.6.0 - Configuration & Presets ⚙️
+**Target:** Q1 2026 (January-February)
+**Priority:** 🔥 CRITICAL
+
+> **Why Critical:** All competitors (SonarQube, ESLint, dependency-cruiser) have configuration. Without this, Guardian cannot be customized for different teams/projects.
+
+### Features
+
+#### 1. Configuration File Support
+
+```javascript
+// guardian.config.js (primary)
+export default {
+    // Zero-config presets
+    preset: 'clean-architecture',  // or 'ddd', 'hexagonal', 'onion'
+
+    // Rule configuration
+    rules: {
+        'hardcode/magic-numbers': 'error',
+        'hardcode/magic-strings': 'warn',
+        'architecture/layer-violation': 'error',
+        'architecture/framework-leak': 'error',
+        'architecture/entity-exposure': 'error',
+        'circular-dependency': 'error',
+        'naming-convention': 'warn',
+        'dependency-direction': 'error',
+        'repository-pattern': 'error',
+    },
+
+    // Custom layer paths
+    layers: {
+        domain: 'src/core/domain',
+        application: 'src/core/application',
+        infrastructure: 'src/adapters',
+        shared: 'src/shared',
+    },
+
+    // Exclusions
+    exclude: [
+        '**/*.test.ts',
+        '**/*.spec.ts',
+        'scripts/',
+        'migrations/',
+        'node_modules/',
+    ],
+
+    // Per-rule ignores
+    ignore: {
+        'hardcode/magic-numbers': {
+            'src/config/constants.ts': [3000, 8080],
+        },
+    },
+}
+```
+
+#### 2. Built-in Presets
+
+```javascript
+// Preset: clean-architecture (default)
+preset: 'clean-architecture'
+// Enables: layer-violation, dependency-direction, naming-convention
+
+// Preset: ddd
+preset: 'ddd'
+// Enables all DDD patterns: aggregates, value-objects, domain-events
+
+// Preset: hexagonal (Ports & Adapters)
+preset: 'hexagonal'
+// Validates port/adapter separation
+
+// Preset: minimal (for prototyping)
+preset: 'minimal'
+// Only critical rules: hardcode, circular-deps
+```
+
+#### 3. Framework-Specific Presets
+
+```javascript
+// NestJS
+preset: 'nestjs-clean-architecture'
+
+// Express
+preset: 'express-clean-architecture'
+
+// Next.js
+preset: 'nextjs-clean-architecture'
+```
+
+#### 4. Configuration Discovery
+
+Support multiple config file formats:
+- `guardian.config.js` (ES modules)
+- `guardian.config.cjs` (CommonJS)
+- `.guardianrc` (JSON)
+- `.guardianrc.json`
+- `package.json` (`guardian` field)
+
+#### 5. CLI Override
+
+```bash
+# Override config from CLI
+guardian check ./src --rule hardcode/magic-numbers=off
+
+# Use specific config file
+guardian check ./src --config custom-config.js
+
+# Generate config
+guardian init --preset clean-architecture
+```
+
+### Implementation Tasks
+- [ ] Create config parser and validator
+- [ ] Implement preset system
+- [ ] Add config discovery logic
+- [ ] Update AnalyzeProject use case to accept config
+- [ ] CLI integration for config override
+- [ ] Add `guardian init` command
+- [ ] Documentation and examples
+- [ ] Tests (config parsing, presets, overrides)
+
+---
+
+## Version 0.7.0 - Visualization & Dependency Graphs 🎨
+**Target:** Q1 2026 (March)
+**Priority:** 🔥 HIGH
+
+> **Why High:** dependency-cruiser's main advantage is visualization. Guardian needs this to compete.
+
+### Features
+
+#### 1. Dependency Graph Visualization
+
+```bash
+# Generate SVG graph
+guardian visualize ./src --output architecture.svg
+
+# Interactive HTML
+guardian visualize ./src --format html --output report.html
+
+# Mermaid diagram for docs
+guardian graph ./src --format mermaid > ARCHITECTURE.md
+
+# ASCII tree for terminal
+guardian visualize ./src --format ascii
+```
+
+#### 2. Layer Dependency Diagram
+
+```mermaid
+graph TD
+    I[Infrastructure Layer] --> A[Application Layer]
+    I --> D[Domain Layer]
+    A --> D
+    D --> S[Shared]
+    A --> S
+    I --> S
+
+    style D fill:#4CAF50
+    style A fill:#2196F3
+    style I fill:#FF9800
+    style S fill:#9E9E9E
+```
+
+#### 3. Violation Highlighting
+
+Visualize violations on graph:
+- 🔴 Circular dependencies (red arrows)
+- ⚠️ Framework leaks (yellow highlights)
+- 🚫 Wrong dependency direction (dashed red arrows)
+- ✅ Correct dependencies (green arrows)
+
+#### 4. Metrics Overlay
+
+```bash
+guardian visualize ./src --show-metrics
+
+# Shows on each node:
+# - File count per layer
+# - Hardcode violations count
+# - Complexity score
+```
+
+#### 5. Export Formats
+
+- SVG (for docs/website)
+- PNG (for presentations)
+- HTML (interactive, zoomable)
+- Mermaid (for markdown docs)
+- DOT (Graphviz format)
+- JSON (for custom processing)
+
+### Implementation Tasks
+- [ ] Implement graph generation engine
+- [ ] Add SVG/PNG renderer
+- [ ] Create Mermaid diagram generator
+- [ ] Build HTML interactive viewer
+- [ ] Add violation highlighting
+- [ ] Metrics overlay system

+
+## Version 0.9.0 - Auto-Fix & Code Generation 🤖
+**Target:** Q2 2026 (May)
+**Priority:** 🚀 GAME-CHANGER (UNIQUE!)
+
+> **Why Game-Changer:** No competitor has intelligent auto-fix for architecture. This makes Guardian unique!
+
+### Features
+
+#### 1. Auto-Fix Hardcode
+
+```bash
+# Fix all hardcode violations automatically
+guardian fix ./src --auto
+
+# Preview changes
+guardian fix ./src --dry-run
+
+# Fix specific types
+guardian fix ./src --type hardcode
+guardian fix ./src --type naming
+```
+
+**Example:**
+
+```typescript
+// Before
+const timeout = 5000
+app.listen(3000)
+
+// After (auto-generated constants.ts)
+export const DEFAULT_TIMEOUT_MS = 5000
+export const DEFAULT_PORT = 3000
+
+// After (fixed code)
+import { DEFAULT_TIMEOUT_MS, DEFAULT_PORT } from './constants'
+const timeout = DEFAULT_TIMEOUT_MS
+app.listen(DEFAULT_PORT)
+```
+
+#### 2. Generate Constants File
+
+```bash
+# Extract all hardcodes to constants
+guardian generate constants ./src --output src/config/constants.ts
+
+# Generated file:
+// src/config/constants.ts
+export const DEFAULT_TIMEOUT_MS = 5000
+export const DEFAULT_PORT = 3000
+export const MAX_RETRIES = 3
+export const API_BASE_URL = 'http://localhost:8080'
+```
+
+#### 3. Fix Naming Violations
+
+```bash
+# Rename files to match conventions
+guardian fix naming ./src --auto
+
+# Before: src/application/use-cases/user.ts
+# After:  src/application/use-cases/CreateUser.ts
+```
+
+#### 4. AI-Friendly Fix Prompts
+
+```bash
+# Generate prompt for AI assistant
+guardian check ./src --format ai-prompt > fix-prompt.txt
+
+# Output (optimized for Claude/GPT):
+"""
+Fix the following Guardian violations:
+
+1. HARDCODE (src/api/server.ts:15)
+   - Replace: app.listen(3000)
+   - With: Extract 3000 to DEFAULT_PORT constant
+   - Location: Create src/config/constants.ts
+
+2. FRAMEWORK_LEAK (src/domain/User.ts:5)
+   - Remove: import { Request } from 'express'
+   - Reason: Domain layer cannot import frameworks
+   - Suggestion: Use dependency injection via interfaces
+
+[Complete fix suggestions...]
+"""
+
+# Then feed to Claude:
+# cat fix-prompt.txt | pbcopy
+# Paste into Claude: "Fix these Guardian violations"
+```
+
+#### 5. Interactive Fix Mode
+
+```bash
+# Interactive fix selection
+guardian fix ./src --interactive
+
+# Prompts:
+# ? Fix hardcode in server.ts:15 (3000)? (Y/n)
+# ? Suggested constant name: DEFAULT_PORT
+#   [Edit name] [Skip] [Fix All]
+```
+
+#### 6. Refactoring Commands
+
+```bash
+# Break circular dependency
+guardian refactor circular ./src/services/UserService.ts
+# Suggests: Extract shared interface
+
+# Fix layer violation
+guardian refactor layer ./src/domain/entities/User.ts
+# Suggests: Move framework imports to infrastructure
+```
+
+### Implementation Tasks
+- [ ] Implement auto-fix engine (AST transformation)
+- [ ] Constants extractor and generator
+- [ ] File renaming system
+- [ ] AI prompt generator
+- [ ] Interactive fix mode
+- [ ] Refactoring suggestions
+- [ ] Safe rollback mechanism
+- [ ] Documentation and examples
+- [ ] Tests (fix scenarios, edge cases)
+
