🛠️ PHASE 3: PROVEN EXECUTION PATTERNS

3.1 Successful Resolution Patterns

Based on actual project fixes:

Pattern 1: SDK Compatibility Issues

# 1. Identify the constraint
flutter pub deps  # Shows dependency conflicts

# 2. Find compatible versions
flutter pub deps --json | jq '.packages[] | select(.name=="package_name")'

# 3. Downgrade systematically
# Edit pubspec.yaml with compatible versions
flutter pub get

# 4. Validate fix
flutter analyze
flutter test

Pattern 2: API Compatibility Issues

# 1. Identify deprecated/missing APIs
flutter analyze | grep "isn't defined"

# 2. Global search and replace
find lib/ -name "*.dart" -exec sed -i 's/oldAPI/newAPI/g' {} \;

# 3. Targeted file fixes
sed -i 's/withValues(alpha: [0-9.]*)/withOpacity(0.4)/g' lib/path/file.dart

# 4. Validate changes
flutter test

Pattern 3: Configuration Issues

# 1. Fix ownership issues
git config --global --add safe.directory $(pwd)

# 2. Clean and refresh
flutter clean
rm -rf .dart_tool/ build/
flutter pub get

# 3. Rebuild dependencies
flutter packages get
flutter packages upgrade --dry-run  # Check what would change

3.2 Change Validation Checkpoints

Checkpoint Sequence (Proven):

# Stage 1: Dependency Resolution
flutter pub get
echo "Exit code: $?"  # Must be 0

# Stage 2: Static Analysis  
flutter analyze
echo "Errors: $(flutter analyze 2>&1 | grep -c 'error •')"  # Must be 0

# Stage 3: Test Execution
flutter test --reporter compact
echo "Tests: $(flutter test --reporter compact | grep -c 'All tests passed')"  # Must be 1

# Stage 4: Build Validation
flutter build web --debug
echo "Build success: $?"  # Must be 0

---

🔒 PHASE 4: PROTECTION STRATEGIES

4.1 Protected Systems Registry

Never Touch During Bug Fixes:

Core Working Features:
  - authentication flow (auth_page.dart)
  - main navigation (app_router.dart)  
  - state management (providers/)
  - test suite (test/widget_test.dart - 8 passing tests)

Stable Dependencies:
  - flutter: sdk (framework dependency)
  - cupertino_icons: ^1.0.8 (iOS icons)
  - material_symbols_icons: 4.2799.0 (Material icons)

Critical Configuration:
  - pubspec.yaml (dependency versions)
  - main.dart (app initialization)
  - supabase_config.dart (backend connection)

4.2 Safe Modification Zones

Low-Risk Areas for Changes:

Documentation:
  - README.md, docs/, wiki/ (no impact on functionality)
  
Configuration:
  - .github/workflows/ (CI/CD improvements)
  - .devcontainer/ (development environment)
  
Non-Critical Features:
  - shared/loading_page.dart (visual only)
  - shared/not_found_page.dart (error handling)

📊 PHASE 5: REAL-WORLD VERIFICATION

5.1 Health Check Script (Proven)

#!/bin/bash
# health_check.sh - Based on actual project needs
set -e

echo "=== QUAEX PROJECT HEALTH CHECK ==="
echo "Date: $(date)"
echo "Directory: $(pwd)"
echo

# Check Flutter environment
echo "🔧 FLUTTER ENVIRONMENT:"
flutter --version | head -3
echo

# Check dependencies
echo "📦 DEPENDENCIES:"
flutter pub deps --no-dev | grep -E "(flutter_riverpod|go_router|supabase)" | head -3
echo "Status: $(flutter pub get 2>&1 | tail -1)"
echo

# Check analysis
echo "🔍 STATIC ANALYSIS:"
ERRORS=$(flutter analyze 2>&1 | grep -c "error •" || echo "0")
WARNINGS=$(flutter analyze 2>&1 | grep -c "info •" || echo "0")
echo "Errors: $ERRORS (must be 0)"
echo "Warnings: $WARNINGS (5 expected - BuildContext async)"
echo

# Check tests  
echo "🧪 TESTS:"
flutter test --reporter compact | tail -1
echo

# Check build capability
echo "🏗️  BUILD CHECK:"
if flutter build web --debug > /dev/null 2>&1; then
    echo "✅ Build: SUCCESS"
else
    echo "❌ Build: FAILED"
fi

echo
echo "=== HEALTH CHECK COMPLETE ==="

5.2 Common Issue Resolution Matrix

Based on actual issues encountered:

Issue	Symptoms	Root Cause	Solution	Prevention
SDK Version Conflict	version solving failed	Package requires newer Dart	Downgrade package version	Pin compatible versions
API Compatibility	method isn't defined	Flutter API changed	Replace with compatible API	Check compatibility before upgrade
Git Ownership	dubious ownership	Container/user mismatch	git config --global --add safe.directory	Include in devcontainer setup
Build Failures	Compilation errors	Missing dependencies	flutter clean && flutter pub get	Regular dependency maintenance
Test Failures	Widget not found	UI changes without test updates	Update test expectations	Keep tests in sync with UI

🚨 EMERGENCY PROTOCOLS

Emergency Recovery (Field Tested)

#!/bin/bash
# emergency_recovery.sh - Return to last known good state

echo "🚨 EMERGENCY RECOVERY INITIATED"

# 1. Stop all processes
echo "Stopping any running Flutter processes..."
killall flutter 2>/dev/null || true
killall dart 2>/dev/null || true

# 2. Save current state for analysis
echo "Saving current state for post-mortem..."
flutter analyze > emergency_analysis.txt 2>&1 || true
flutter pub deps > emergency_deps.txt 2>&1 || true
cp pubspec.yaml emergency_pubspec_backup.yaml

# 3. Clean slate approach
echo "Cleaning build artifacts..."
flutter clean
rm -rf .dart_tool/ build/ .flutter-plugins .flutter-plugins-dependencies

# 4. Restore known good pubspec (if backup exists)
if [ -f "pubspec.yaml.backup" ]; then
    echo "Restoring known good pubspec.yaml..."
    cp pubspec.yaml.backup pubspec.yaml
fi

# 5. Reinstall dependencies
echo "Reinstalling dependencies..."
flutter pub get

# 6. Validate recovery
echo "Validating recovery..."
if flutter analyze | grep -q "No issues found"; then
    echo "✅ RECOVERY SUCCESSFUL"
    flutter test --reporter compact
else
    echo "❌ RECOVERY INCOMPLETE - Manual intervention required"
    echo "Check emergency_analysis.txt for details"
fi
