+
+## Development Servers
+
+### Angular (Port 3000)
+```bash
+cd apps/angular
+npm start
+```
+Used as reference implementation and baseline for visual regression testing.
+
+### React (Port 3001)
+```bash
+cd apps/react
+npm run dev
+```
+Test target for Cypress and comparison target for BackstopJS.
+
+## Execution Flow for Tasks 56-59
+
+### Task 56: Generate Angular Baseline
+1. Start Angular on port 3000: `cd apps/angular && npm start`
+2. Run baseline capture: `cd e2e && npm run backstop:reference`
+3. Verify 12+ images in `bitmaps_reference/`
+4. Commit baseline: `git add e2e/backstop/bitmaps_reference/ && git commit`
+
+### Task 57: Compare React to Baseline
+1. Start React on port 3001: `cd apps/react && npm run dev`
+2. Run comparison: `cd e2e && npm run backstop:test`
+3. Review HTML report: `e2e/backstop/html_report_react/index.html`
+4. Document differences found
+
+### Task 58: Fix Visual Differences
+1. For each failed scenario in report:
+   - Identify React component/CSS
+   - Compare Angular vs React styles
+   - Update React SCSS to match
+   - Rerun test for that scenario
+2. Iterate until all tests pass
+
+### Task 59: Full Validation
+1. Run Cypress: `npm run cypress:run`
+2. Run final BackstopJS: `npm run backstop:test`
+3. Generate validation report
+4. Commit all results
+
+## Required Data-TestID Attributes
+
+The BackstopJS scenarios depend on these data-testid values being present in both Angular and React:
+
+- `data-testid="page-loaded"` - Main page container
+- `data-testid="board-page-loaded"` - Board page container
+- `data-testid="schedule-page-loaded"` - Schedule page container
+- `data-testid="flights-map-loaded"` - Flights map container
+
+**Status:** Ready selectors defined in config, implementation status depends on Task 11-55 completion.

+   - Ensure all data-testid attributes are present
+   - Verify component parity with Angular
+
+2. **Pre-Task 56 Verification:**

+
+### Post-Migration
+1. Deploy validated React application
+2. Archive Angular application
+3. Update documentation
+4. Release version 2.0
