---

## Part 1: Critical Issues Fixed

### ✅ 1. Tenant Tag Format Consistency
**File**: `crossplane-provider-proxmox/pkg/proxmox/client.go`
- **Fix**: Standardized tenant tag format to `tenant_{id}` (underscore) in both write and read operations
- **Impact**: Multi-tenancy filtering now works correctly

### ✅ 2. API Authentication Header Format
**File**: `api/src/adapters/proxmox/adapter.ts`
- **Fix**: Corrected `Authorization` header from `PVEAPIToken=${token}` to `PVEAPIToken ${token}` (space)
- **Impact**: All 8 API calls now authenticate correctly

### ✅ 3. Hardcoded Node Names
**File**: `gitops/infrastructure/compositions/vm-ubuntu.yaml`
- **Fix**: Added optional patch to dynamically set node from `spec.parameters.node`
- **Impact**: Flexible deployment to any node

### ✅ 4. Credential Secret Configuration
**File**: `crossplane-provider-proxmox/examples/provider-config.yaml`
- **Fix**: Removed misleading `key` field, added documentation
- **Impact**: Clear configuration guidance

### ✅ 5. Error Handling in API Adapter
**File**: `api/src/adapters/proxmox/adapter.ts`
- **Fix**: Added comprehensive error handling, URL encoding, input validation
- **Impact**: Better error messages and reliability

---

## Part 2: High Priority Issues Fixed

### ✅ 6. Storage Default Inconsistency
**Files**: `crossplane-provider-proxmox/pkg/proxmox/client.go` (2 locations)
- **Fix**: Changed cloud-init storage default from `"local"` to `"local-lvm"`
- **Impact**: Consistent storage defaults prevent configuration errors

### ✅ 7. Site Name Standardization
**Files**: 
- `crossplane-provider-proxmox/examples/provider-config.yaml`
- `crossplane-provider-proxmox/examples/vm-example.yaml`
- **Fix**: Updated examples to use consistent site names (`us-sfvalley`)
- **Impact**: Examples match actual production usage

### ✅ 8. Network Bridge Validation
**Files**: 
- `crossplane-provider-proxmox/pkg/proxmox/networks.go` (NEW)
- `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller.go`
- **Fix**: Added `NetworkExists()` function and validation in controller
- **Impact**: Catches network misconfigurations before VM creation

### ✅ 9. Image Handling Logic Improvements
**File**: `crossplane-provider-proxmox/pkg/proxmox/client.go`
- **Fix**: 
  - Improved template ID detection (validates VMID range)
  - Replaced blank disk creation with error (VMs without OS fail to boot)
- **Impact**: Clearer error messages, prevents unbootable VMs

### ✅ 10. importdisk API Improvements
**File**: `crossplane-provider-proxmox/pkg/proxmox/client.go`
- **Fix**: 
  - Improved version detection (case-insensitive)
  - Better comments explaining best-effort check
- **Impact**: More reliable API support detection

---

## Part 3: Medium Priority Issues Fixed

### ✅ 11. Memory/Disk Parsing Consolidation
**Files**:
- `crossplane-provider-proxmox/pkg/utils/parsing.go` (NEW)
- `crossplane-provider-proxmox/pkg/proxmox/client.go`
- `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller.go`
- **Fix**: 
  - Created shared utility functions: `ParseMemoryToMB()`, `ParseMemoryToGB()`, `ParseDiskToGB()`
  - Updated all code to use shared functions
  - Case-insensitive parsing for consistency
- **Impact**: Single source of truth, consistent parsing across codebase

### ✅ 12. Comprehensive Input Validation
**Files**:
- `crossplane-provider-proxmox/pkg/utils/validation.go` (NEW)
- `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller.go`
- **Fix**: Added validation functions:
  - `ValidateVMID()` - Range check (100-999999999)
  - `ValidateVMName()` - Format and length validation
  - `ValidateMemory()` - Min/max checks (128MB-2TB)
  - `ValidateDisk()` - Min/max checks (1GB-100TB)
  - `ValidateCPU()` - Range check (1-1024)
  - `ValidateNetworkBridge()` - Format validation
  - `ValidateImageSpec()` - Template ID, volid, or image name
- **Impact**: Catches invalid configurations early with clear error messages

### ✅ 13. Enhanced Error Categorization
**File**: `crossplane-provider-proxmox/pkg/controller/virtualmachine/errors.go`
- **Fix**: Added authentication error category (non-retryable)
- **Impact**: Better retry logic, prevents unnecessary retries on auth failures

### ✅ 14. Status Update Logic Improvements
**File**: `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller.go`
- **Fix**: 
  - Initial status set to `"created"` instead of actual status (may not be accurate)
  - IP address only updated if actually present
  - Status updated from actual VM status in subsequent reconciles
- **Impact**: More accurate status reporting

### ✅ 15. Cloud-init Handling Improvements
**Files**:
- `crossplane-provider-proxmox/pkg/proxmox/client.go`
- `crossplane-provider-proxmox/apis/v1alpha1/virtualmachine_types.go`
- **Fix**: 
  - Improved error logging for cloud-init failures
  - Better documentation of UserData field
- **Impact**: Better visibility into cloud-init configuration issues

---

## Part 4: Code Quality Improvements

### ✅ 16. Shared Utilities Package
**Files**: `crossplane-provider-proxmox/pkg/utils/` (NEW)
- Created organized utility package with:
  - Parsing functions (memory, disk)
  - Validation functions (all input types)
- **Impact**: Better code organization, DRY principle

### ✅ 17. Network API Functions
**File**: `crossplane-provider-proxmox/pkg/proxmox/networks.go` (NEW)
- Added `ListNetworks()` and `NetworkExists()` functions
- **Impact**: Network validation and discovery capabilities

### ✅ 18. Documentation Improvements
**Files**: Multiple
- Updated field comments and documentation
- Added validation documentation
- Clarified behavior in examples
- **Impact**: Better developer experience
