Review Summary

This PR introduces a helpful UX improvement by bringing the Launchpad window to the front after successful authentication. The implementation is clean, focused, and follows repository standards. All critical checks pass ✅

✅ What's Good

1. Linting passes completely - All 4 checks pass (ruff format, ruff check, pyright, mypy)
2. Commit message follows conventional commits - fix: prefix is correct
3. Architecture compliance - The change is properly scoped to the GUI frame module
4. Code quality - Well-documented with clear docstring, defensive programming with null check
5. Smart implementation - Uses set_always_on_top(True) temporarily to bring window forward, then reverts to normal behavior
6. Security - No secrets, no sensitive data, no HIPAA concerns

📋 Observations (Non-Blocking)

1. Testing Coverage

Current state: The gui module has no dedicated test directory (tests/aignostics/gui/ doesn't exist). GUI testing happens at the module level (e.g., tests/aignostics/system/gui_test.py).

Impact: This change affects two async functions:

• _user_info_ui_load() - called on timer interval for initial login
• _user_info_ui_relogin() - called when user clicks "Re-authenticate now"

Recommendation: Consider adding an integration test to verify the window-to-front behavior. Example test structure:

# tests/aignostics/application/gui_test.py or similar location
@pytest.mark.integration
async def test_gui_window_brought_to_front_after_login(user: User, monkeypatch) -> None:
    """Test that native window is brought to front after successful authentication."""
    # Mock PlatformService.get_user_info to return user info
    # Mock app.native.main_window with a MagicMock
    # Verify set_always_on_top(True), show(), set_always_on_top(False) called in order

However, given:

• GUI testing in this repo happens at module level (not in tests/aignostics/gui/)
• The change is defensive (checks if app.native.main_window)
• The behavior only affects native builds (doesn't break web mode)
• Existing GUI tests will catch breakage indirectly

This is not a blocker - the risk is low and the change improves UX.

2. Alternative Approaches (Optional Discussion)

The current implementation uses a "temporary always-on-top" pattern:

app.native.main_window.set_always_on_top(True)
app.native.main_window.show()
app.native.main_window.set_always_on_top(False)

Alternative considerations (not requesting changes, just for awareness):

• Some platforms have raise_() or activateWindow() methods that don't require toggling always-on-top
• The current approach works cross-platform and is battle-tested in desktop frameworks

Verdict: The current approach is pragmatic and safe ✅

3. Code Location

The helper function _bring_window_to_front() is defined inside the frame() context manager (line 53). This is appropriate since:

• It's only used within this context manager
• It needs access to app from NiceGUI imports
• It's a private function (prefix _)

No changes needed, just noting this is the correct pattern for the modulith architecture.

Conventional Commits	✅ Pass	Commit: fix: bring Launchpad to front after successful login

Recommendation

APPROVE ✅ - This PR is ready to merge.

The change is a focused UX improvement that:

• Solves a real usability problem (hidden window after auth)
• Follows all repository standards
• Passes all linting checks
• Is low-risk (defensive programming with null checks)
• Doesn't introduce breaking changes

The lack of dedicated tests for this specific behavior is consistent with the current testing strategy for the GUI module (integration testing at module level rather than framework component level).

---

Optional follow-up (not blocking this PR):

• Consider adding GUI framework component tests in a future PR if window focus behavior becomes critical
• Document the "window to front" pattern in src/aignostics/gui/CLAUDE.md if this pattern gets reused

Great work, @olivermeyer! 🎉

Bug: app.native.main_window.set_always_on_top() method does not exist on the pywebview.Window object, leading to an AttributeError.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

When _bring_window_to_front() is called, app.native.main_window.set_always_on_top(True) will raise an AttributeError because the pywebview.Window object, wrapped by app.native.main_window, does not have a set_always_on_top() method. This will crash the authentication flow, preventing the Launchpad from being brought to front after login and potentially breaking the user authentication experience entirely.

💡 Suggested Fix

Replace app.native.main_window.set_always_on_top(True) with app.native.main_window.on_top = True and app.native.main_window.set_always_on_top(False) with app.native.main_window.on_top = False.

Potential issue: When `_bring_window_to_front()` is called,
`app.native.main_window.set_always_on_top(True)` will raise an `AttributeError` because
the `pywebview.Window` object, wrapped by `app.native.main_window`, does not have a
`set_always_on_top()` method. This will crash the authentication flow, preventing the
Launchpad from being brought to front after login and potentially breaking the user
authentication experience entirely.

I don't know that this can be covered by automated tests. I'll wait until Nico confirms this works on his Windows machine before merging.
