-# Issue: Architectural Layer Independence Test Runner with Chaos Engineering
-
-## 🎯 Objective
-Create a sophisticated test runner that validates architectural layer independence through controlled error injection (chaos engineering). This tool will systematically inject failures into each layer and verify that only dependent layers fail, while independent layers remain unaffected.
-
-## 🧠 Motivation
-Our current architectural test organization ensures proper execution order, but doesn't validate that layers are truly independent. Hidden dependencies between layers can:
-- Create fragile architecture that breaks unexpectedly
-- Violate clean architecture principles
-- Make debugging and maintenance difficult
-- Reduce system resilience
-
-## 🏗️ Technical Design
-
-### Core Components
-
-#### 1. Chaos Injection Engine
-```python
-class ArchitecturalChaosInjector:
-    """Systematically inject controlled failures into architectural layers."""
-
-    def inject_layer_failure(self, layer: str, strategy: str) -> ContextManager
-    def restore_layer_state(self, layer: str) -> None
-    def validate_injection_safety(self, strategy: str) -> bool
-```
-
-#### 2. Dependency Validation Matrix
-```python
-LAYER_DEPENDENCY_MATRIX = {
-    "foundation": {
-        "should_fail_when_broken": ["infrastructure", "integration", "domain", "service", "application", "presentation"],
-        "should_remain_independent": [],
-        "failure_tolerance": 0  # Foundation failures are critical
-    },
-    "infrastructure": {
-        "should_fail_when_broken": ["service", "application", "presentation"],
-        "should_remain_independent": ["domain"],  # Domain should be infrastructure-agnostic
-        "failure_tolerance": 20  # Some infrastructure failures may be recoverable
-    },
-    # ... complete matrix for all layers
-}
-```
-
-#### 3. Error Injection Strategies
-
-| **Layer** | **Injection Strategy** | **Implementation** | **Safety Level** |
-|-----------|------------------------|-------------------|-------------------|
-| **Foundation** | Database corruption | Mock SQLite connection failures | High |
-| **Foundation** | File system errors | Temporary permission changes | Medium |
-| **Infrastructure** | Cache corruption | Corrupt cache file contents | High |
-| **Infrastructure** | Config errors | Inject invalid configuration values | High |
-| **Integration** | Network failures | Mock HTTP timeout responses | High |
-| **Integration** | API errors | Return error responses from Gitea API | High |
-| **Domain** | Business logic errors | Inject invalid model states | Medium |
-| **Service** | Coordination failures | Break service interface contracts | Medium |
-| **Application** | Workflow errors | Inject use case execution failures | High |
-| **Presentation** | CLI errors | Break command argument parsing | High |
-
-#### 4. Test Execution Pipeline
-```
-1. Baseline Run: Execute all tests normally (establish baseline)
-2. For each layer:
-   a. Inject controlled failure
-   b. Run all layer tests
-   c. Analyze failure patterns
-   d. Detect dependency violations
-   e. Restore clean state
-3. Generate comprehensive violation report
-4. Provide remediation recommendations
-```
-
-## 📊 Expected Outcomes
-
-### Success Metrics
-- **Zero Dependency Violations**: Only expected layers fail when dependencies break
-- **Complete Layer Isolation**: Independent layers remain unaffected by unrelated failures
-- **Predictable Failure Patterns**: Failures follow documented dependency graph
-
-### Violation Detection
-- **Upward Dependencies**: Lower layers depending on higher layers (architectural violation)
-- **Cross-Layer Dependencies**: Unexpected dependencies between parallel layers
-- **Shared State Issues**: Tests affecting each other through global state
-
-### Reporting
-```
-🏗️ Architectural Chaos Test Results
-=====================================
-
-Foundation Layer Injection:
-✅ Expected failures: Infrastructure(98), Service(24), Application(16), Presentation(1)
-❌ Unexpected failures: Domain(2) - VIOLATION DETECTED
-
-Infrastructure Layer Injection:
-✅ Expected failures: Service(24), Application(16), Presentation(1)
-✅ Independent layers: Foundation(10), Domain(14) - ARCHITECTURE SOUND
-
-Violations Found: 1
-- Domain layer has hidden dependency on Foundation layer
-- Recommendation: Review domain models for infrastructure coupling
