# Warden Core - AI Code Guardian (Python)

> "AI writes code. Warden guards production."

**Status:** ✅ **PRODUCTION READY** - Core execution engine + 6 validation frames implemented and tested!

---

## 🎯 What is Warden?

Warden is an AI-powered code quality gate that validates AI-generated code before it reaches production. It analyzes code for security vulnerabilities, resilience patterns, edge cases, and architectural consistency.

### The Problem
- AI tools (Cursor, Copilot, Claude Code) generate code rapidly
- Developers merge AI code with minimal review
- "It works" ≠ "It's production-ready"
- Security vulnerabilities, edge cases, and fragile patterns slip through

### The Solution
Warden provides **automated validation** with:
- 🔒 **Security Analysis** - SQL injection, XSS, hardcoded secrets
- ⚡ **Resilience Testing** - Error handling, retry mechanisms, timeouts
- 🎲 **Edge Case Validation** - Type safety, null handling, boundary testing
- 📐 **Property Testing** - Idempotency, invariants
- 🏗️ **Architectural Checks** - SOLID principles, file size limits
- 💪 **Performance Analysis** - N+1 queries, memory leaks

---

## ✅ Implementation Status

### Phase 1: Core Execution Engine (COMPLETE!)
- ✅ **PipelineOrchestrator** - Sequential 5-stage pipeline execution
- ✅ **FrameExecutor** - Parallel frame execution with priority-based groups
- ✅ **CodeAnalyzer** - Python AST-based analysis + metrics
- ✅ **CodeClassifier** - Pattern-based frame recommendation
- ✅ **Correlation ID tracking** - Full traceability
- ✅ **Structured logging** - Production-ready observability
- ✅ **Fail-fast** - Stops on blocker failures

### Phase 2: Validation Frames (COMPLETE!)
- ✅ **SecurityFrame** (Critical, Blocker) - 3 vulnerability types detected
- ✅ **ChaosEngineeringFrame** (High) - Resilience patterns
- ✅ **FuzzTestingFrame** (High) - Type safety + edge cases
- ✅ **PropertyTestingFrame** (Medium) - Idempotency checks
- ✅ **ArchitecturalConsistencyFrame** (Medium) - SOLID + file size
- ✅ **StressTestingFrame** (Low) - Performance bottlenecks

### Phase 3: CLI (COMPLETE!)
- ✅ **Modern CLI** - Built with Typer + Rich
- ✅ **Validate Command** - Single file validation with beautiful output
- ✅ **Scan Command** - Directory scanning with progress bars
- ✅ **Rich Tables** - Color-coded results, priority indicators
- ✅ **Progress Indicators** - Spinners, bars, time estimates
- ✅ **Exit Codes** - CI/CD integration support
- ✅ **Verbose Mode** - Detailed issue display

### Phase 4: Precision & Repair (Phase 39 - LSP)
- ✅ **LSP Client & Manager** - Async JSON-RPC architecture
- ✅ **Orphan Detection 2.0** - 100% accurate unused code detection (LSP References)
- ✅ **Deep Diagnostics** - Compiler-grade error detection (LSP Diagnostics)
- ✅ **Symbol Graph** - Precise project structure mapping

### Phase 5: Declarative Rules & Hygiene (Complete!)
- ✅ **Custom Rule Engine** - Define your own rules in YAML (Regex-based).
- ✅ **"Detect, Warn, Suggest" Workflow** - Warden finds the issue, explains why it's wrong, and suggests the correct path. It does not auto-fix, ensuring you remain in control.
- ✅ **Project Hygiene** - Automatically detects misplaced files (Logs, artifacts, temp scripts) effectively cleaning your project root.

### Phase 6: Package Manager & Chaos Engineering (NEW! ✨)
- ✅ **Dependency Management** - `warden.yaml` for declarative frame dependencies
- ✅ **Deterministic Locking** - `warden.lock` ensures reproducible builds across teams
- ✅ **Chaos-Resilient Installation** - SHA-256 integrity checks with drift detection
- ✅ **Self-Healing** - Automatic repair of tampered or corrupted frames
- ✅ **Hub Discovery** - `warden search` to find validation frames from the marketplace
- ✅ **Health Diagnostics** - `warden doctor` validates project readiness with severity levels (Error vs Warning)
- ✅ **Retry Logic** - Resilient to transient network failures during installation

### 🧠 The Warden Advantage: LSP + Semantic Synergy
Warden uses a unique **"Pipeline Synergy"** architecture:
1.  **Precision (LSP)**: The `AnalysisPhase` and `OrphanFrame` use the Language Server to find issues with *compiler certainty* (e.g., "Method X is never called").
2.  **Context (Semantic)**: The `FortificationPhase` takes these exact findings and uses **Vector Search** to find "Similar Secure Patterns" in your codebase.
3.  **Result**: You get a fix that is not just syntactically correct, but matches your team's *coding style*.

### Infrastructure (Previously Complete)
- ✅ Pipeline models (PipelineRun, Step, SubStep, Summary)
- ✅ YAML configuration system (Parser, Exporter, Validator)
- ✅ Priority system (frame sorting, execution groups)
- ✅ Panel JSON compatibility (all models)
- ✅ 4 ready-to-use templates

---

## 📦 Package Manager & Chaos Engineering

### Why a Package Manager?
Warden validation frames are like plugins - they extend Warden's capabilities. The package manager ensures:
- **Reproducibility**: Same validation rules across all team members
- **Security**: Integrity checks prevent supply chain attacks
- **Reliability**: Self-healing when frames are corrupted or tampered with

### `warden.yaml` - Dependency Declaration
```yaml
version: "1.0.0"
project:
  name: my-app
  language: python

dependencies:
  architectural: "latest"           # From Warden Hub
  security:
    git: "https://github.com/org/custom-security.git"
    ref: "main"                      # Or specific commit/tag
  my-custom-frame:
    path: "./local-frames/custom"   # Local development

frames:
  - architectural
  - security
```

### `warden.lock` - Deterministic Installation
Automatically generated lockfile with:
- **Exact commit hashes** for Git dependencies
- **SHA-256 content hashes** for installed frames
- **Drift detection** - Compares local files against lockfile

```yaml
packages:
  architectural:
    git: "https://github.com/warden-ai/frame-architectural.git"
    ref: "a3f12d9"                    # Exact commit
    content_hash: "sha256:abc123..."  # Directory checksum
  security:
    git: "https://github.com/org/custom-security.git"
    ref: "7b8c4e1"
    content_hash: "sha256:def456..."
```

### Chaos Engineering Principles

**Steady State**: Frames should always match their lockfile hash

**Drift Detection**: 
```bash
$ warden install
� Checking integrity...
  ⚠️  Drift detected in architectural frame
  ♻️  Auto-repairing from lockfile...
  ✅ Restored to known good state
```

**Self-Healing**:
- Detects unauthorized modifications
- Automatically re-fetches corrupted frames
- Prevents "works on my machine" scenarios

**Retry Logic**:
- 3 automatic retries for network failures
- Exponential backoff (future enhancement)
- Graceful degradation

### `warden search` - Hub Discovery

**Search the Marketplace**:
```bash
$ warden search "security"
┌─────────────┬─────────────────────┬──────────┬───────┐
│ ID          │ Description         │ Category │ Stats │
├─────────────┼─────────────────────┼──────────┼───────┤
│ security    │ SQL, XSS, Secrets   │ Security │ ⭐ 245│
│ env-sec     │ .env Best Practices │ Security │ ⭐ 89 │
└─────────────┴─────────────────────┴──────────┴───────┘
```

**Semantic Search** (Local Codebase):
```bash
$ warden search --local "error handling pattern"
📍 Found 12 similar code blocks in your project
```

### `warden doctor` - Health Diagnostics

Pre-flight check before scanning:

```bash
$ warden doctor

🔍 Checking Python Version...
  ✔ Python 3.11 (compatible)

🔍 Checking Core Configuration...
  ✔ warden.yaml found.

🔍 Checking Warden Directory...
  ✔ .warden directory exists.

🔍 Checking Installed Frames...
  ✔ All 2 dependent frames are installed and verified.

🔍 Checking Custom Rules...
  ✔ All 3 configured rules are present.

🔍 Checking Environment & API Keys...
  ⚠️  Missing: LLM API Key. AI features will be disabled. (Degraded Experience)

🔍 Checking Tooling (LSP/Git)...
  ✔ Core tools (git, LSP) are available.

🔍 Checking Semantic Index...
  ⚠️  Semantic index not found. Run 'warden index' for context-aware analysis. (Degraded Experience)

✅ Your project is healthy and ready for a scan!
(Warnings may limit some advanced features, but core scanning is operational)
```

**Severity Levels**:
- 🔴 **ERROR** (Critical) - Blocks scanning: Missing config, frames, or Git
- 🟡 **WARNING** (Degraded) - Limits features: Missing API keys, LSP, or index
- 🟢 **SUCCESS** - Fully operational

**What Doctor Checks**:
1. **Python Version** - Ensures 3.9+ for compatibility
2. **Core Configuration** - Validates `warden.yaml` presence
3. **Warden Directory** - Ensures `.warden` exists
4. **Installed Frames** - Detects missing or drifted frames
5. **Custom Rules** - Validates rule file paths
6. **Environment & API Keys** - Checks LLM provider keys (optional)
7. **Tooling** - Verifies Git (critical) and LSP servers (optional)
8. **Semantic Index** - Checks vector database (optional)

## 🎯 Key Features

### 1. Priority-Based Execution
Frames execute in priority order:
```
Critical → High → Medium → Low
Security → Chaos → Fuzz/Property/Arch → Stress
```

Parallel mode groups by priority:
```
Group 1: [Security] (critical, blocker)
Group 2: [Chaos] (high)
Group 3: [Fuzz, Property, Architectural] (medium - parallel)
Group 4: [Stress] (low)
```

### 2. Fail-Fast Behavior
- Security frame is a **blocker**
- Pipeline stops immediately on security failures
- Saves time, prevents vulnerable code from progressing

### 3. Pattern-Based Detection
- AST parsing for Python code
- Regex patterns for security vulnerabilities
- Characteristic detection (async, external calls, database, etc.)
- Smart frame recommendation

### 4. Panel JSON Compatibility
- All models support Panel integration
- camelCase ↔ snake_case conversion
- Exact TypeScript type matching

### 5. Smart Caching & Incremental Scanning
- **Composite Cache Key**: Combines file content + config hash + Warden version.
- **Environment Aware**: Automatic invalidation if rules or configuration change.
- **Dependency Tracking**: Language-agnostic extraction (Python, JS, TS, Go, Java) to identify transitive impact.
- **Blazing Fast**: Skips expensive analysis for unchanged files (0 LLM tokens).
- **Semantic Risk Analysis**: Re-analyzes impacted files even if content is unchanged, focusing on integration consistency.

---

## 📋 Validation Frames

### 1. SecurityFrame (Critical, Blocker: True)
**Detects:**
- SQL injection patterns (f-strings with SQL)
- Command injection (shell=True, eval, exec)
- Hardcoded secrets (API keys, passwords, tokens)
- Path traversal vulnerabilities

**Example:**
```python
# ❌ DETECTED
API_KEY = "sk-1234567890abcdef"
query = f"SELECT * FROM users WHERE id = '{user_id}'"
os.system(f"cat {filename}")

# ✅ SAFE
API_KEY = os.getenv("API_KEY")
query = text("SELECT * FROM users WHERE id = :user_id")
subprocess.run(['cat', filename], shell=False)
```

### 2. ChaosEngineeringFrame (High, Blocker: False)
**Validates:**
- Error handling patterns (no bare except)
- Timeout protection for async code
- Retry mechanisms for external calls

### 3. FuzzTestingFrame (High, Blocker: False)
**Validates:**
- Type hints on functions
- Null/None handling for user input
- Edge case validation

### 4. PropertyTestingFrame (Medium, Blocker: False)
**Validates:**
- Idempotency (database operations)
- Invariants preservation

### 5. ArchitecturalConsistencyFrame (Medium, Blocker: False)
**Validates:**
- File size limits (<500 lines)
- Function size limits (<50 lines)
- Class count per file

### 6. StressTestingFrame (Low, Blocker: False)
**Detects:**
- N+1 query patterns
- Large loop iterations
- Potential memory leaks (global variables)
