+# Dependency Scans - Both Auditors
+
+Scans for dependency compatibility and peer conflicts. Run during both R18 and R19 audits.
+
+---
+
+## Current Versions
+
+```bash
+# All react-related package versions in one shot
+cat package.json | python3 -c "
+import sys, json
+d = json.load(sys.stdin)
+deps = {**d.get('dependencies',{}), **d.get('devDependencies',{})}
+keys = ['react', 'react-dom', 'react-router', 'react-router-dom',
+        '@testing-library/react', '@testing-library/jest-dom',
+        '@testing-library/user-event', '@apollo/client', 'graphql',
+        '@emotion/react', '@emotion/styled', 'jest', 'enzyme',
+        'react-redux', '@reduxjs/toolkit', 'prop-types']
+for k in keys:
+    if k in deps:
+        print(f'{k}: {deps[k]}')
+" 2>/dev/null
+```
+
+---
+
+## Peer Dependency Conflicts
+
+```bash
+# All peer dep warnings (must be 0 before migration completes)
+npm ls 2>&1 | grep -E "WARN|ERR|peer|invalid|unmet"
+
+# Count of peer errors
+npm ls 2>&1 | grep -E "WARN|ERR|peer|invalid|unmet" | wc -l
+
+# Specific package peer dep requirements
+npm info @testing-library/react peerDependencies 2>/dev/null
+npm info @apollo/client peerDependencies 2>/dev/null
+npm info @emotion/react peerDependencies 2>/dev/null
+npm info react-router-dom peerDependencies 2>/dev/null
+```
+

+
+## Enzyme Detection (R18 Blocker)
+
+```bash
+# In package.json
+cat package.json | python3 -c "
+import sys, json
+d = json.load(sys.stdin)
+deps = {**d.get('dependencies',{}), **d.get('devDependencies',{})}
+enzyme = {k: v for k, v in deps.items() if 'enzyme' in k.lower()}
+if enzyme:
+    print('BLOCKER - Enzyme found:', enzyme)
+else:
+    print('No Enzyme - OK')
+" 2>/dev/null
+
+# Enzyme adapter files
+find . -name "enzyme-adapter*" -not -path "*/node_modules/*" 2>/dev/null
+```
+
+---
+
+## React Router Version Check
+
+```bash
+ROUTER=$(node -e "console.log(require('./node_modules/react-router-dom/package.json').version)" 2>/dev/null)
+echo "react-router-dom version: $ROUTER"
+
+# If v5 - flag for assessment
+if [[ $ROUTER == 5* ]]; then
+  echo "WARNING: react-router v5 found - requires scope assessment before upgrade"
+  echo "Run router migration scope scan:"
+  echo "  Routes: $(grep -rn "<Route\|<Switch\|<Redirect" src/ --include="*.js" --include="*.jsx" | grep -v "\.test\." | wc -l) hits"
+  echo "  useHistory: $(grep -rn "useHistory()" src/ --include="*.js" --include="*.jsx" | grep -v "\.test\." | wc -l) hits"
+fi
+```
+

+
+## Lock File Consistency
+
+```bash
+# Check lockfile is in sync with package.json
+npm ls --depth=0 2>&1 | head -20
+
+# Check for duplicate react installs (can cause hooks errors)
+find node_modules -name "package.json" -path "*/react/package.json" 2>/dev/null \
+  | grep -v "node_modules/node_modules" \
+  | xargs grep '"version"' | sort -u
+```
