## What Was Accomplished
### 1. Complete Script Inventory
- Identified **29 script files** in `/scripts` directory
- Analyzed all scripts referenced in `.vscode/tasks.json`
- Classified scripts by priority, complexity, and use case
### 2. AgentSkills.io Specification Research
- Thoroughly reviewed the [agentskills.io specification](https://agentskills.io/specification)
- Understood the SKILL.md format requirements:
- YAML frontmatter with required fields (name, description)

The plan includes:
#### A. Directory Structure
- Complete `.agentskills/` directory layout for all 24 skills
- Proper naming conventions (lowercase, hyphens, no special characters)
- Organized by category (testing, security, utility, linting, docker)
#### B. Detailed Skill Specifications
For each of the 24 skills to be created:
- Complete SKILL.md frontmatter with all required fields
- Skill-specific metadata (original script, exit codes, parameters)
- Documentation structure with purpose, usage, examples
- Related skills cross-references
#### C. Implementation Phases
**Phase 1** (Days 1-3): Core Testing & Build

- Version checking, cache clearing, version bumping, DB recovery
**Phase 4** (Days 10-12): Linting & Docker
- 12 linting and Docker management skills
- Complete migration and deprecation of `/scripts`
#### D. Task Configuration Updates
- Complete `.vscode/tasks.json` with all new paths
- Preserves existing task labels and behavior

# DNS Encryption Key Rotation - Phase 2 Implementation Complete
## Overview
Implemented Phase 2 (Key Rotation Automation) from the DNS Future Features plan, providing zero-downtime encryption key rotation with multi-version support, admin API endpoints, and comprehensive audit logging.

#### Changes:
#### Changes
- Added `KeyVersion int` field with `gorm:"default:1;index"` tag
- Tracks which encryption key version was used for each provider's credentials
- Enables version-aware decryption and rotation status reporting
### 3. DNS Provider Service Integration

- Added `rotationService *crypto.RotationService` field
- Gracefully falls back to basic encryption if RotationService initialization fails
- **Create** method: Uses `EncryptWithCurrentKey()` returning (ciphertext, version)

**File**: `backend/internal/api/routes/routes.go`
#### Changes:
#### Changes
- Added conditional encryption management route group under `/api/v1/admin/encryption`
- Routes only registered if `RotationService` initializes successfully
- Prevents app crashes if encryption keys are misconfigured
### 6. Audit Logging Enhancements
**File**: `backend/internal/services/security_service.go`
#### Improvements:
#### Improvements
- Added `sync.WaitGroup` for graceful goroutine shutdown
- `Close()` now waits for background goroutine to finish processing
- `Flush()` method for testing: waits for all pending audit logs to be written
- Silently ignores errors from closed databases (common in tests)
#### Event Types:

### Step-by-Step Process
1. **Current State**: All providers encrypted with key version 1
```bash
export CHARON_ENCRYPTION_KEY="<current-32-byte-key>"
```
2. **Prepare Next Key**: Set the new key without restarting
```bash
export CHARON_ENCRYPTION_KEY_NEXT="<new-32-byte-key>"
```
3. **Trigger Rotation**: Call admin API endpoint
```bash
curl -X POST https://your-charon-instance/api/v1/admin/encryption/rotate \
-H "Authorization: Bearer <admin-token>"
```
4. **Verify Rotation**: All providers now use version 2
```bash
curl https://your-charon-instance/api/v1/admin/encryption/status \
-H "Authorization: Bearer <admin-token>"
```
5. **Promote Next Key**: Make it the current key (requires restart)
```bash
export CHARON_ENCRYPTION_KEY="<new-32-byte-key>" # Former NEXT key
export CHARON_ENCRYPTION_KEY_V1="<old-32-byte-key>" # Keep as legacy

6. **Future Rotations**: Repeat process with new NEXT key
### Rollback Procedure:
### Rollback Procedure
If rotation fails mid-process:
1. Providers still using old key (version 1) remain accessible
2. Failed providers logged in `RotationResult.FailedProviders`
3. Retry rotation after fixing issues
4. Fallback decryption automatically tries all available keys
To revert to previous key after full rotation:
1. Set previous key as current: `CHARON_ENCRYPTION_KEY="<old-key>"`
2. Keep rotated key as legacy: `CHARON_ENCRYPTION_KEY_V2="<rotated-key>"`
3. All providers remain accessible via fallback mechanism

### Registry Pattern
- **Global singleton**: `dnsprovider.Global()` provides single source of truth
- **Thread-safe**: RWMutex protects concurrent access
- **Sorted types**: `Types()` returns alphabetically sorted provider names
- **Existence check**: `IsSupported()` for quick validation
### Security Model
- **Signature verification**: SHA-256 hash of plugin file
- **Permission checks**: Reject world-writable directories (0o002)
- **Platform restriction**: Reject Windows (Go plugin limitations)
- **Sandbox execution**: Plugins run in same process but with limited scope

- Access to cloud provider metadata services (AWS: 169.254.169.254)

- DNS resolution with context timeout (prevents DNS slowloris)
- Validates **ALL** resolved IPs before connection (prevents IP hopping)
- Uses first valid IP only (prevents DNS rebinding)
- Atomic resolution → validation → connection sequence (prevents TOCTOU)

All critical and high-priority SSRF vulnerabilities have been addressed with comprehensive validation, testing, and logging. The implementation follows security best practices with defense-in-depth protection and user-friendly error handling.
**Next Steps:**
1. Deploy to production with monitoring enabled
2. Set up alerts for SSRF attempts
3. Address MEDIUM-002 in future sprint (lower priority)

### 1. Two-Phase Processing
**Rationale:** Separates provider detection from credential resolution, enabling cleaner code and better error handling.
**Implementation:**
- **Phase 1:** Build provider config list, detect multi-credential flag
- **Phase 2:** Resolve per-domain credentials using helper function
### 2. Interface-Based Design
**Rationale:** Enables comprehensive testing without real Caddy server dependency.
**Implementation:**
- Created `CaddyClient` interface
- Modified `NewManager` signature to accept interface
- Implemented `MockClient` for testing
### 3. Credential Resolution Priority
**Rationale:** Provides flexible matching while ensuring most specific match wins.
**Priority Order:**
1. Exact match (example.com → example.com)
2. Wildcard match (app.example.com → *.example.com)
3. Catch-all (any domain → empty zone_filter)

**Schema changes:** None required
- ProxyHost relationship is purely GORM-level (no migration needed)
- Existing `proxy_host_id` foreign key already exists
- Backward compatible with existing data
**Query impact:**
- One additional JOIN per `checkHost()` call
- Negligible performance overhead (monitors already cached)
- Preload prevents N+1 query pattern

### Issue: Monitor still shows as "down" after fix
**Check 1:** Verify ProxyHost relationship is loaded
```bash
docker exec charon sqlite3 /app/data/charon.db \
"SELECT name, proxy_host_id FROM uptime_monitors WHERE name = 'YourHost';"
```
- If `proxy_host_id` is NULL → Expected to use URL extraction
- If `proxy_host_id` has value → Relationship should load
**Check 2:** Check logs for port resolution
```bash
docker logs charon 2>&1 | grep "TCP check port resolution" | tail -5
```
- Look for `actual_port` in log output
- Verify it matches your `forward_port` in proxy_hosts table
**Check 3:** Verify backend port is reachable
```bash
# From within Charon container
docker exec charon nc -zv 172.20.0.11 5690
```
- Should show "succeeded" if port is open
- If connection fails → Backend container issue, not monitoring issue
### Issue: Backend container unreachable
**Common causes:**
- Backend container not running (`docker ps | grep container_name`)
- Incorrect `forward_host` IP in proxy host config
- Network isolation (different Docker networks)

- TCP check: <100ms (success) → proceed to HTTP check
