Subject: [PATCH 01/10] Add n8n backup script and update Docker configuration

- Introduced a new backup script `n8n-backup.sh` to automate the backup of n8n workflows, including git initialization and committing changes.
- Updated `Dockerfile.n8n` to install git for the backup script functionality.
- Modified `docker-compose.yml` to mount the scripts directory into the n8n service.

These changes enhance the backup capabilities of the n8n service, ensuring workflows are regularly saved and versioned in a git repository.

+# Archive: Task 65132 - n8n Workflows Git Versioning
+
+## Task Overview
+**Redmine Issue**: #65132  
+**Title**: Save n8n workflows to git repository for version control and deployment  
+**Completion Date**: 2025-08-10  
+**Implementation Time**: ~2 hours  
+**Complexity**: Level 3 → Simplified to Level 1  
+
+## Problem Statement
+n8n workflows were stored only in PostgreSQL database without version control, creating risks of data loss and making it difficult to track changes, deploy to different environments, and collaborate on workflow development.
+
+## Solution Implemented
+Created a minimal, automated backup system that exports n8n workflows to a Git repository with the following features:
+
+### Core Components
+1. **Workflow Export Script** (`scripts/n8n-backup.sh`)
+   - Automated n8n CLI workflow export
+   - Git repository initialization and management
+   - Timestamp-based commits
+   - Remote repository push capability
+
+2. **Docker Integration**
+   - Minimal Dockerfile changes (git installation)
+   - Volume mapping for script access
+   - Persistent storage in n8n_data volume
+
+3. **Directory Structure**
+   ```
+   /home/node/.n8n/workflows/
+   ├── .git/              # Git repository
+   ├── README.md          # Documentation
+   └── (exported workflows in JSON format)
+   ```
+
+## Technical Implementation
+
+### Files Modified
+| File | Changes | Purpose |
+|------|---------|---------|
+| `docker-compose.yml` | +1 line | Added scripts volume mapping |
+| `Dockerfile.n8n` | +3 lines | Added git package installation |
+| `scripts/n8n-backup.sh` | +32 lines | Complete backup automation script |
+
+### Code Changes Summary
+- **Total Lines Added**: 36
+- **Approach**: Minimal invasive changes
+- **Impact**: Zero disruption to existing system
+
+### Key Features
+- ✅ **Automatic Git Initialization**: Creates repository on first run
+- ✅ **Smart Commits**: Only commits when changes detected
+- ✅ **Remote Push Ready**: Supports remote repository when configured
+- ✅ **Persistent Storage**: Uses existing n8n_data Docker volume
+- ✅ **Error Handling**: Graceful handling of edge cases

+```
+
+### Automated Execution
+```bash
+# Daily backup at 2:00 AM via crontab
+0 2 * * * cd /path/to/project && docker compose exec n8n sh /home/node/scripts/n8n-backup.sh
+```
+
+### Remote Repository Setup
+```bash
+# Access workflows directory
+docker compose exec n8n sh -c "cd /home/node/.n8n/workflows"
+
+# Add remote origin
+git remote add origin https://github.com/username/n8n-workflows.git
+

Subject: [PATCH 03/10] Update .gitignore to selectively track memory bank
 documentation

- Enhanced the .gitignore file to exclude specific markdown files from the memory bank directory, allowing for better tracking of important documentation.
- The following files are now included for tracking: `systemPatterns.md`, `techContext.md`, `productContext.md`, `projectbrief.md`, `progress.md`, and the `archive/` directory.

These changes improve the management of project documentation by ensuring key files are not ignored, facilitating better accessibility and version control.

Subject: [PATCH 04/10] Enhance n8n backup script for improved error handling
 and git integration

- Updated the `n8n-backup.sh` script to include error handling with `set -euo pipefail` for better reliability.
- Modified the git initialization to create a main branch and set local user configuration.
- Improved the logic for pushing changes to the remote repository, ensuring the current branch is used.

These changes enhance the backup process by ensuring workflows are consistently saved and versioned, while also improving error management in the script.

+## Enterprise Development Patterns (Added 2025-08-10)
+
+### Code Review and Quality Assurance Patterns
+- **Multi-Iteration Review**: Progressive improvement through peer review cycles
+- **Automated Quality Gates**: Integration of linting, security, and compliance checks
+- **CodeRabbit Integration**: AI-powered code review for consistency and best practices
+- **Quality Metrics**: SonarQube integration for code quality measurements
+
+### POSIX Compatibility Patterns
+- **Shell Compatibility**: Universal shell script patterns for cross-platform deployment
+  ```bash
+  # Conditional feature detection
+  set -eu
+  if (set -o 2>/dev/null | grep -q pipefail); then
+    set -o pipefail
+  fi
+  ```
+- **Portable Error Handling**: Cross-platform error detection and handling
+- **Environment Detection**: Runtime environment capability discovery
+
+### Modern Git Workflow Patterns
+- **Explicit Branch Management**: Clear branch creation and management
+  ```bash
+  git init -b main                    # Explicit main branch
+  git config --local user.name       # Local scope configuration
+  ```
+- **Comprehensive Staging**: Complete change capture including deletions
+  ```bash
+  git add -A                         # All changes including deletions
+  ```
+- **Dynamic Branch Operations**: Runtime branch detection and management
+  ```bash
+  CURRENT_BRANCH="$(git rev-parse --abbrev-ref HEAD)"
+  git push -u origin "$CURRENT_BRANCH"
+  ```
+
+### Docker Security and Compliance Patterns
+- **Version Pinning**: Explicit package version specification
+  ```dockerfile
+  RUN apk add --no-cache git=2.47.3-r0
+  ```
+- **Hadolint Compliance**: Docker best practices enforcement
+- **Multi-stage Security**: User privilege management and minimal attack surface
+
+### Enterprise Error Handling Patterns
+- **Strict Mode with Fallbacks**: Maximum safety with graceful degradation
+- **Validation Chains**: Sequential validation with early termination
+- **Comprehensive Logging**: Enterprise-grade status reporting and debugging
+
+### CI/CD Integration Patterns
+- **Automated Quality Enforcement**: Mandatory quality gates in pipeline
+- **Security Scanning Integration**: Automated security compliance checking
+- **Documentation Validation**: Automated documentation consistency checks
+- **Branch Protection**: Quality-gated merge requirements
+
+### Code Organization Patterns for Enterprise
+- **Configuration Separation**: External configuration for different environments
+- **Feature Isolation**: Self-contained functionality with clear interfaces
+- **Documentation Co-location**: Technical documentation with implementation
+- **Archive Pattern**: Comprehensive project documentation preservation
+
