+# Runner Dependency Management Process
+
+## Overview
+
+This document outlines the automated dependency management process for the GitHub Actions Runner, designed to ensure we maintain up-to-date and secure dependencies while providing predictable release cycles.
+
+## Release Schedule
+
+- **Monthly Runner Releases**: New runner versions are released monthly
+- **Weekly Dependency Checks**: Automated workflows check for dependency updates every Monday
+- **Security Patches**: Critical security vulnerabilities are addressed immediately outside the regular schedule
+
+## Automated Workflows
+
+**Note**: These workflows are implemented across separate PRs for easier review and independent deployment. Each workflow includes comprehensive error handling and security-focused vulnerability detection.
+
+### 1. Foundation Labels
+
+- **Workflow**: `.github/workflows/setup-labels.yml` (PR #4024)
+- **Purpose**: Creates consistent dependency labels for all automation workflows
+- **Labels**: `dependencies`, `security`, `typescript`, `needs-manual-review`
+- **Prerequisite**: Must be merged before other workflows for proper labeling
+
+### 2. Node.js Version Updates
+
+- **Workflow**: `.github/workflows/node-upgrade.yml`
+- **Schedule**: Mondays at 6:00 AM UTC
+- **Purpose**: Updates Node.js 20 and 24 versions in `src/Misc/externals.sh`
+- **Source**: [nodejs.org](https://nodejs.org) and [actions/alpine_nodejs](https://github.com/actions/alpine_nodejs)
+- **Priority**: First (NPM depends on current Node.js versions)
+
+### 3. NPM Security Audit
+
+- **Primary Workflow**: `.github/workflows/npm-audit.yml` ("NPM Audit Fix")
+  - **Schedule**: Mondays at 7:00 AM UTC
+  - **Purpose**: Automated security vulnerability detection and basic fixes
+  - **Location**: `src/Misc/expressionFunc/hashFiles/`
+  - **Features**: npm audit, security patch application, PR creation
+  - **Dependency**: Runs after Node.js updates for optimal compatibility
+
+- **Fallback Workflow**: `.github/workflows/npm-audit-typescript.yml` ("NPM Audit Fix with TypeScript Auto-Fix")
+  - **Trigger**: Manual dispatch only
+  - **Purpose**: Manual security audit with TypeScript compatibility fixes
+  - **Use Case**: When scheduled workflow fails or needs custom intervention
+  - **Features**: Enhanced TypeScript auto-repair, graduated security response
+  - **How to Use**:
+    1. If the scheduled "NPM Audit Fix" workflow fails, go to Actions tab
+    2. Select "NPM Audit Fix with TypeScript Auto-Fix" workflow
+    3. Click "Run workflow" and optionally specify fix level (auto/manual)
+    4. Review the generated PR for TypeScript compatibility issues
+
+### 4. .NET SDK Updates
+
+- **Workflow**: `.github/workflows/dotnet-upgrade.yml`
+- **Schedule**: Mondays at midnight UTC
+- **Purpose**: Updates .NET SDK and package versions with build validation
+- **Features**: Global.json updates, NuGet package management, compatibility checking
+- **Independence**: Runs independently of Node.js/NPM updates
+
+### 5. Docker/Buildx Updates
+
+- **Workflow**: `.github/workflows/docker-buildx-upgrade.yml` ("Docker/Buildx Version Upgrade")
+- **Schedule**: Mondays at midnight UTC
+- **Purpose**: Updates Docker and Docker Buildx versions with multi-platform validation
+- **Features**: Container security scanning, multi-architecture build testing
+- **Independence**: Runs independently of other dependency updates
+
+### 6. Dependency Monitoring
+
+- **Workflow**: `.github/workflows/dependency-check.yml` ("Dependency Status Check")
+- **Schedule**: Mondays at 11:00 AM UTC
+- **Purpose**: Comprehensive status report of all dependencies with security audit
+- **Features**: Multi-dependency checking, npm audit status, build validation, choice of specific component checks
+- **Summary**: Runs last to capture results from all morning dependency updates
+
+## Release Process Integration
+
+### Pre-Release Checklist
+
+Before each monthly runner release:
+
+1. **Check Dependency PRs**:
+
+   ```bash
+   # List all open dependency PRs
+   gh pr list --label "dependencies" --state open
+   
+   # List only automated weekly dependency updates
+   gh pr list --label "dependencies-weekly-check" --state open
+   
+   # List only custom dependency automation (not dependabot)
+   gh pr list --label "dependencies-not-dependabot" --state open
+   ```
+
+2. **Run Manual Dependency Check**:
+   - Go to Actions tab → "Dependency Status Check" → "Run workflow"
+   - Review the summary for any outdated dependencies
+
+3. **Review and Merge Updates**:
+   - Prioritize security-related updates
+   - Test dependency updates in development environment
+   - Merge approved dependency PRs
+
+### Vulnerability Response
+
+#### Critical Security Vulnerabilities
+
+- **Response Time**: Within 24 hours
+- **Process**:
+  1. Assess impact on runner security
+  2. Create hotfix branch if runner data security is affected
+  3. Expedite patch release if necessary
+  4. Document in security advisory if applicable
+
+#### Non-Critical Vulnerabilities
+
+- **Response Time**: Next monthly release
+- **Process**:
+  1. Evaluate if vulnerability affects runner functionality
+  2. Include fix in regular dependency update cycle
+  3. Document in release notes
+
+## Monitoring and Alerts
+
+### GitHub Actions Workflow Status
+
+- All dependency workflows create PRs with the `dependencies` label
+- Failed workflows should be investigated immediately
+- Weekly dependency status reports are generated automatically
+
+### Manual Checks
+
+You can manually trigger dependency checks:
+
+- **Full Status**: Run "Dependency Status Check" workflow
+- **Specific Component**: Use the dropdown to check individual dependencies
+
+## Dependency Labels
+
+All automated dependency PRs are tagged with labels for easy filtering and management:
+
+### Primary Labels
+
+- **`dependencies`**: All automated dependency-related PRs
+- **`dependencies-weekly-check`**: Automated weekly dependency updates from scheduled workflows
+- **`dependencies-not-dependabot`**: Custom dependency automation (not created by dependabot)
+- **`security`**: Security vulnerability fixes and patches  
+- **`typescript`**: TypeScript compatibility and type definition updates
+- **`needs-manual-review`**: Complex updates requiring human verification
+
+### Technology-Specific Labels
+
+- **`node`**: Node.js version updates
+- **`javascript`**: JavaScript runtime and tooling updates
+- **`npm`**: NPM package and security updates
+- **`dotnet`**: .NET SDK and NuGet package updates
+- **`docker`**: Docker and container tooling updates
+
+### Workflow-Specific Branches
+
+- **Node.js updates**: `chore/update-node` branch
+- **NPM security fixes**: `chore/npm-audit-fix-YYYYMMDD` and `chore/npm-audit-fix-with-ts-repair` branches
+- **NuGet/.NET updates**: `feature/dotnetsdk-upgrade/{version}` branches
+- **Docker updates**: `feature/docker-buildx-upgrade` branch
+
+## Special Considerations
+
+### Node.js Updates
+
+When updating Node.js versions, remember to:
+
+1. Create a corresponding release in [actions/alpine_nodejs](https://github.com/actions/alpine_nodejs)
+2. Follow the alpine_nodejs getting started guide
+3. Test container builds with new Node versions
+
+### .NET SDK Updates
+
+- Only patch versions are auto-updated within the same major.minor version
+- Major/minor version updates require manual review and testing
+
+### Docker Updates
+
+- Updates include both Docker Engine and Docker Buildx
+- Verify compatibility with runner container workflows
+
+## Troubleshooting
+
+### Common Issues
+
+1. **NPM Audit Workflow Fails**:
+   - Check if `package.json` exists in `src/Misc/expressionFunc/hashFiles/`
+   - Verify Node.js setup step succeeded
+
+2. **Version Detection Fails**:
+   - Check if upstream APIs are available
+   - Verify parsing logic for version extraction
+
+3. **PR Creation Fails**:
+   - Ensure `GITHUB_TOKEN` has sufficient permissions
+   - Check if branch already exists
+
+### Contact
+
+For questions about the dependency management process:
+
+- Create an issue with the `dependencies` label
+- Review existing dependency management workflows
+- Consult the runner team for security-related concerns
+
+## Metrics and KPIs
+
+Track these metrics to measure dependency management effectiveness:
+
+- Number of open dependency PRs at release time
+- Time to merge dependency updates
+- Number of security vulnerabilities by severity
+- Release cycle adherence (monthly target)
