+# P0 Security & Testing Improvements
+
+## Summary
+Implemented critical P0 improvements for TimeTracker focusing on security hardening and test coverage.
+
+## Changes Made
+
+### 1. CSRF Protection Enabled ✅
+
+**Files Modified:**
+- `app/config.py`
+- `app/__init__.py`
+
+**Changes:**
+1. **Enabled CSRF Protection by Default** (`app/config.py` line 78)
+   - Changed `WTF_CSRF_ENABLED` from `False` to `True` in base Config class
+   - Now enabled in development and production environments
+   - Disabled only in testing environment (as expected)
+
+2. **Production Config Enhanced** (`app/config.py` line 135-136)
+   - Added `REMEMBER_COOKIE_SECURE = True` for production
+   - Ensures remember-me cookies are only sent over HTTPS
+
+3. **API Routes Exempted** (`app/__init__.py` line 294)
+   - Added `csrf.exempt(api_bp)` to exempt API blueprint from CSRF
+   - JSON API endpoints use authentication, not CSRF tokens
+   - Prevents breaking API functionality while securing form submissions
+
+**Why This Matters:**
+- Prevents Cross-Site Request Forgery attacks
+- Critical security vulnerability now patched
+- Forms are now protected while API endpoints remain functional
+
+**Template Support:**
+Templates already had CSRF tokens implemented:
+- `{{ csrf_token() }}` in base.html meta tag
+- Form fields with `csrf_token` value in all forms
+- No template changes needed ✅
+
+---
+
+### 2. Smoke Test Markers Added ✅
+
+**Files Modified:**
+- `tests/test_invoices.py`
+- `tests/test_new_features.py`
+- `pytest.ini`
+
+**Changes:**
+
+1. **Invoice Tests** (`tests/test_invoices.py`)
+   - Added `@pytest.mark.smoke` to critical tests:
+     - `test_invoice_creation` (line 76-77)
+     - `test_invoice_item_creation` (line 109-110)
+     - `test_invoice_totals_calculation` (line 127-128)
+   - Added `@pytest.mark.invoices` marker for categorization
+
+2. **New Feature Tests** (`tests/test_new_features.py`)
+   - Added import: `import pytest` (line 1)
+   - Added smoke markers to:
+     - `test_burndown_endpoint_available` (line 6-7)
+     - `test_saved_filter_model_roundtrip` (line 25-26)
+   - Added `@pytest.mark.api` and `@pytest.mark.models` for categorization
+
+3. **Pytest Configuration** (`pytest.ini`)
+   - Added `invoices` marker definition (line 44)
+   - Now recognized as a valid marker
+
+**Why This Matters:**
+- CI/CD workflow already runs smoke tests: `pytest -m smoke -v --tb=short --no-cov`
+- Critical functionality is now tested on every build
+- Fast feedback loop for developers
+- Aligns with existing test infrastructure
+
+---
+
+## Test Coverage Status
+
+### Smoke Tests Now Include:
+- ✅ App creation and initialization
+- ✅ Database table creation
+- ✅ Health check endpoint
+- ✅ Login page accessibility
+- ✅ User and admin creation
+- ✅ Project model operations
+- ✅ Time entry model operations
+- ✅ **Invoice creation and calculations** (NEW)
+- ✅ **Invoice item management** (NEW)
+- ✅ **Burndown API endpoint** (NEW)
+- ✅ **Saved filter model** (NEW)
+- ✅ Security critical tests
+
+### CI/CD Integration
+The GitHub Actions workflow (`.github/workflows/cd-development.yml`) already runs smoke tests on line 68:
+```yaml
+pytest -m smoke -v --tb=short --no-cov
+```
+
+These changes ensure critical features are tested before deployment.
+
+---
+
+## Verification Steps
+
+### To Test Locally:
+```bash
+# Run only smoke tests (fast)
+pytest -m smoke -v --tb=short --no-cov
+
+# Run all tests
+pytest -v
+
+# Run specific test categories
+pytest -m invoices -v
+pytest -m "smoke and invoices" -v
+```
+
+### To Verify CSRF Protection:
+1. Start the application in production mode
+2. Try to submit a form without CSRF token → Should fail with 400 error
+3. Try to call API endpoints → Should work (exempted)
+4. Submit forms with CSRF token → Should work normally
+
+---
+
+## Security Impact
+
+### Before:
+- ❌ CSRF protection disabled
+- ❌ Forms vulnerable to CSRF attacks
+- ⚠️ Limited smoke test coverage for invoice features
+
+### After:
+- ✅ CSRF protection enabled by default
+- ✅ All forms protected with CSRF tokens
+- ✅ API routes properly exempted
+- ✅ Production cookies secured (HTTPS only)
+- ✅ Comprehensive smoke test coverage
+
+---
+
+## Breaking Changes
+**None** - This is a non-breaking security enhancement:
+- Templates already had CSRF token support
+- API routes are properly exempted
+- Testing environment still has CSRF disabled
+- Existing functionality preserved
+
+---
+
+## Next Steps (Optional)
+
+### Additional P1+ Improvements:
+1. **Rate Limiting Enforcement** - Config exists but needs activation
+2. **Security Headers Enhancement** - Add more strict CSP rules
+3. **Session Security** - Add session timeout and rotation
+4. **Audit Logging** - Track security-relevant events
+5. **Content Security Policy** - Tighten existing CSP
+
+### Testing Enhancements:
+1. Add CSRF-specific tests
+2. Expand invoice test coverage
+3. Add security penetration tests
+4. Increase overall code coverage beyond 50%

+- No environment variable changes needed
+
+### Production Environment:
+- CSRF protection enforced
+- Cookies secured (HTTPS only)
+- API endpoints functional
+- **Verify SECRET_KEY is properly set** (not default value)
+
+### Testing Environment:
+- CSRF protection disabled (by design)
+- No impact on existing test suite
+- New smoke tests integrated
+
+---
+
+## Author & Date

+
+---
+
+## Rollback Instructions
+If issues arise (unlikely):
+
+1. **Disable CSRF in development** (temporary):
+   ```python
+   # app/config.py line 78
+   WTF_CSRF_ENABLED = False
+   ```
+
+2. **Revert all changes**:
+   ```bash
+   git checkout HEAD -- app/config.py app/__init__.py
+   git checkout HEAD -- tests/test_invoices.py tests/test_new_features.py
+   git checkout HEAD -- pytest.ini
+   ```
+
+---
+
+**Ready for production deployment! ✅**
