Find the line in _includes/panchanga-widget-full.html that says:

Step 2: Run Tests

./scripts/feature-workflow.py test

Expected: All tests pass (80 unit tests + E2E tests)

Step 3: Commit Task 3

./scripts/feature-workflow.py commit "feat: Connect modal form to URL state and calculation

- Add modal open/close event handlers
- Add location autocomplete in modal
- Add form validation (location + date required)
- Update URL state via history.pushState() on calculation
- Auto-close modal after successful calculation
- Show validation errors in modal (not alert boxes)
- E2E tests for modal form submission and URL updates
- All tests passing

    });

Step 2: Test & Commit Task 4

./scripts/feature-workflow.py test
./scripts/feature-workflow.py commit "feat: Add browser history support for back/forward navigation

- Listen for popstate events on browser back/forward
- Restore state from URL when history navigates
- Recalculate and display results for restored state
- E2E tests for browser back button navigation
- All tests passing

Fixes #0045"

Task 5: Add Page Load Scenarios (Cached Location + No URL)

Update the autoLoadAndCalculate function in _includes/panchanga-widget-full.html:

    // Auto-load cached location and calculate on page load
    const autoLoadAndCalculate = async () => {
      // Check URL params first (highest priority)
      if (urlDate && urlLocationId) {
        // URL has complete state - auto-calculate
        setTimeout(() => {
          document.getElementById('panchanga-calculate-btn').click();
        }, 500);
      } else if (effectiveLocation && !urlLocationId) {
        // Have cached location but no URL location param
        // Auto-load location but wait for user to select date
        selectedLocation = effectiveLocation;
        locationInput.value = effectiveLocation.name;
        document.getElementById('panchanga-current-location').textContent = `📍 ${effectiveLocation.name} (${effectiveLocation.latitude.toFixed(4)}, ${effectiveLocation.longitude.toFixed(4)})`;
      }
      // If no URL and no cache: show empty collapsed view (user must click to start)
    };

    // Run auto-load on page load
    await autoLoadAndCalculate();

Test & Commit Task 5

./scripts/feature-workflow.py test
./scripts/feature-workflow.py commit "feat: Add page load scenarios (URL params, cached location)

- URL with both date and locationid: auto-calculate on load
- Cached location, no URL: auto-populate location field
- No cache, no URL: show collapsed view waiting for input
- E2E tests for all page load scenarios
- All tests passing

Fixes #0045"

Task 6: Add Complete Workflow E2E Tests

Add to tests/e2e/panchangam.spec.js:

test.describe('Complete Workflow Tests', () => {
  test('User can share URL and see results on another browser', async ({ page }) => {
    // First browser: make calculation
    await page.goto(`${BASE_URL}/panchangam/`);
    const changeBtn = page.locator('[data-testid="panchanga-change-location-btn"]');
    await changeBtn.click();

    const locationInput = page.locator('[data-testid="panchanga-modal-location-input"]');
    await locationInput.fill('New York');
    await page.waitForTimeout(300);

    const suggestion = page.locator('.panchanga-suggestion-item').first();
    const exists = await suggestion.isVisible().catch(() => false);
    if (exists) {
      await suggestion.click();
    }

    const dateInput = page.locator('[data-testid="panchanga-modal-date-input"]');
    await dateInput.fill('2026-07-04');

    const calculateBtn = page.locator('[data-testid="panchanga-modal-calculate-btn"]');
    await calculateBtn.click();

    await page.waitForTimeout(1000);

    const url = page.url();
    const sunrise1 = await page.locator('[id="result-sunrise"]').textContent();

    // Verify URL structure
    expect(url).toMatch(/date=2026-07-04/);
    expect(url).toMatch(/locationid=/);

    // In real scenario, share this URL
    // For test, just verify the data is there
    expect(sunrise1).toBeTruthy();
  });

  test('Modal shows validation errors for incomplete form', async ({ page }) => {
    await page.goto(`${BASE_URL}/panchangam/`);
    const changeBtn = page.locator('[data-testid="panchanga-change-location-btn"]');
    await changeBtn.click();

    // Try to calculate without entering location
    const calculateBtn = page.locator('[data-testid="panchanga-modal-calculate-btn"]');
    await calculateBtn.click();

    await page.waitForTimeout(300);

    // Error message should be visible
    const error = page.locator('[id="panchanga-modal-error"]');
    const isVisible = await error.isVisible().catch(() => false);
    expect(isVisible).toBe(true);

    // Modal should still be open
    const modal = page.locator('[data-testid="panchanga-modal"]');
    const modalVisible = await modal.isVisible();
    expect(modalVisible).toBe(true);
  });

  test('Responsive modal works on mobile viewport', async ({ page }) => {
    await page.setViewportSize({ width: 375, height: 667 });
    await page.goto(`${BASE_URL}/panchangam/`);

    const changeBtn = page.locator('[data-testid="panchanga-change-location-btn"]');
    await changeBtn.click();

    const modal = page.locator('[data-testid="panchanga-modal"]');
    const isVisible = await modal.isVisible();
    expect(isVisible).toBe(true);
  });
});

Test & Commit Task 6

./scripts/feature-workflow.py test
./scripts/feature-workflow.py commit "test: Add comprehensive E2E tests for modal workflow

- Complete workflow: select location/date, calculate, verify results
- Shareable URL test: URL structure validation
- Form validation test: incomplete form shows error
- Responsive design test: modal fits on mobile viewport
- All E2E tests passing

Fixes #0045"

Task 7: Final Testing & Verification

# 1. Run full test suite
./scripts/feature-workflow.py test

# 2. Manual verification checklist:
# □ Modal opens/closes correctly
# □ Location autocomplete works
# □ Date picker works
# □ Calculate button validates both fields
# □ Error messages appear in modal
# □ Modal closes after successful calculation
# □ Results display in collapsed view
# □ URL updates with date and locationid params
# □ Browser back button restores previous calculation
# □ Shared URL loads correct location/date automatically
# □ Cached location loads when visiting without URL params
# □ Modal is responsive on mobile
# □ No console errors
# □ E2E test suite passes
# □ Unit test suite passes
# □ Simple widget (pradoshakalapooja.md) is unchanged

# 3. Final commit
./scripts/feature-workflow.py commit "test: Verify all tests pass and no regressions

- Full test suite passing (unit + E2E)
- Manual testing checklist complete
- No regressions in existing functionality
- Simple widget unchanged and working
- Modal feature fully implemented and tested

Closes #0045"

# 4. Update task status
# Edit tasks/0045-url-state-modal-panchangam.md
# Change:
# status: open
# To:
# status: done
# completed: 2026-06-06

# 5. Merge to main
