+# NPM Package Age Policy
+
+## Requirement
+
+All npm packages must be **at least 2 weeks old** before they can be used in this project. This ensures:
+- Package stability
+- Security vulnerability disclosure time
+- Compliance with organizational security policies
+
+## How It Works
+
+### 1. Package Version Pinning
+
+The project uses exact version pinning in `package.json` to prevent automatic updates:
+
+```json
+{
+  "dependencies": {
+    "@angular/core": "19.2.7",  // Exact version, not "^19.2.7" or "~19.2.7"
+    // ...
+  }
+}
+```
+
+The `frontend/.npmrc` file enforces this:
+```
+save-exact=true
+package-lock=true
+```
+
+### 2. Automated Age Checking
+
+Use the provided script to verify all packages meet the 2-week requirement:
+
+```bash
+# Check if all packages are at least 2 weeks old
+node scripts/check-package-age.js
+```
+
+This script:
+- Queries npm registry for publish dates
+- Calculates age of each package
+- Fails if any package is newer than 14 days
+- Shows detailed age information for all packages
+
+### 3. Installation Process
+
+**Always use `npm ci` instead of `npm install`:**
+
+```bash
+cd frontend
+npm ci  # Installs exact versions from package-lock.json
+```
+
+**Why `npm ci`?**
+- Uses exact versions from `package-lock.json`
+- Doesn't update `package-lock.json`
+- Ensures reproducible builds
+- Faster than `npm install`
+
+## Updating Packages
+
+When you need to add or update packages:
+
+### Step 1: Add Package to package.json
+
+```bash
+# Find a version that's at least 2 weeks old
+npm view <package-name> time
+
+# Add exact version to package.json
+"dependencies": {
+  "new-package": "1.2.3"
+}
+```
+
+### Step 2: Verify Age
+
+```bash
+node scripts/check-package-age.js
+```
+
+### Step 3: Update Lock File
+
+```bash
+cd frontend
+npm install --package-lock-only
+```
+
+### Step 4: Install and Test
+
+```bash
+npm ci
+npm run build:prod
+```
+
+## CI/CD Integration
+
+Add the age check to your CI/CD pipeline:
+
+### GitLab CI Example
+
+```yaml
+verify_package_age:
+  stage: validate
+  image: node:18-alpine
+  script:
+    - node scripts/check-package-age.js
+  only:
+    - merge_requests
+    - main
+```
+
+### GitHub Actions Example
+
+```yaml
+- name: Check Package Age
+  run: node scripts/check-package-age.js
+```
+
+## Troubleshooting
+
+### "Package is too new" Error
+
+If a package fails the age check:
+
+1. **Find an older version:**
+   ```bash
+   npm view <package-name> versions --json
+   npm view <package-name>@<older-version> time
+   ```
+
+2. **Update package.json with older version**
+
+3. **Re-run age check:**
+   ```bash
+   node scripts/check-package-age.js
+   ```
+
+### Can't Find Old Enough Version
+
+If no version meets the 2-week requirement:
+- Wait until the package is at least 2 weeks old
+- Look for alternative packages
+- Request an exception through your security team
+
+## Example Workflow
+
+```bash
+# 1. Check current package ages
+node scripts/check-package-age.js
+
+# 2. If all pass, install dependencies
+cd frontend
+npm ci
+
+# 3. Build application
+npm run build:prod
+
+# 4. For air-gapped deployment
+../scripts/build-for-airgap.sh
+```
+
+## Scripts Reference
+
+| Script | Purpose |
+|--------|---------|
+| `scripts/check-package-age.js` | Verify all packages are ≥ 2 weeks old |
+| `scripts/pin-old-versions.sh` | Helper script to validate and pin versions |
+| `scripts/build-for-airgap.sh` | Build frontend for air-gapped deployment |
+
+## Best Practices
+
+1. **Always commit `package-lock.json`**
+   - Ensures everyone uses the same versions
+   - Required for reproducible builds
+
+2. **Use `npm ci` in CI/CD**
+   - Faster than `npm install`
+   - Enforces lock file versions
+   - Prevents surprises
+
+3. **Regular audits**
+   ```bash
+   # Check for security vulnerabilities
+   npm audit
+
+   # Check package ages
+   node scripts/check-package-age.js
+   ```
+
+4. **Version ranges to avoid**
+   - ❌ `^1.2.3` (allows minor/patch updates)
+   - ❌ `~1.2.3` (allows patch updates)
+   - ❌ `*` or `latest` (allows any version)
+   - ✅ `1.2.3` (exact version only)
+
+## Package Age Check Output
+
+```
+Checking package ages (must be at least 2 weeks old)...
+
+✓ @angular/common@19.2.7 - 45 days old
+✓ @angular/compiler@19.2.7 - 45 days old
+✓ rxjs@7.8.0 - 180 days old
+❌ new-package@1.0.0 - 5 days old (published 2025-01-12)
+
+================================================================================
+
+❌ FAILED: 1 package(s) are newer than 2 weeks:
+
+  - new-package@1.0.0 (5 days old, published 2025-01-12)
+```
