Code Review Report: Story 3.4 - PWA Install Prompt & Manifest

Date: 2026-01-23 Reviewer: Antigravity Status: ✅ APPROVED (with minor notes)

Executive Summary

The implementation for Story 3.4 (PWA Install Prompt & Manifest) is complete and verifies against all Acceptance Criteria. The architecture follows the specified "Logic Sandwich" pattern, keeping UI components clean and delegating logic to services and stores. Unit tests are present and passing.

Acceptance Criteria Verification

Criteria	Status	Notes
Valid `manifest.json`	✅ PASS	Implemented in `src/app/manifest.ts` with standalone mode and correct icons.
Install Prompt Logic	✅ PASS	`InstallPromptService` correctly handles `beforeinstallprompt` and `appinstalled` events.
Custom UI	✅ PASS	`InstallPromptButton` provides a non-intrusive UI element.
Engagement Logic	✅ PASS	`EngagementTracker` and `InstallPromptButton` strictly enforce showing the prompt only after engagement (1+ completed session).
Standalone Mode	✅ PASS	Correctly configured in manifest and detected by service.

Architectural Analysis

Strengths

Logic Sandwich Pattern: InstallPromptButton only relies on InstallPromptStore (state) and EngagementTracker (data), calling InstallPromptService for actions. This is excellent separation of concerns.
State Management: Zustand store (InstallPromptStore) effectively manages the ephemeral beforeinstallprompt event.
Atomic Selectors: The UI component uses atomic selectors (s => s.isInstallable) to minimize re-renders.

Issues Found

Minor / Maintenance

Lint Error: src/services/install-prompt-service.ts contains an explicit any cast.
```
(window.navigator as any).standalone === true; // iOS Safari
```
Recommendation: Extend the Navigator interface in a d.ts file to include the standalone property for better type safety, or disable the lint rule for this specific line if type augmentation is overkill.

Verification

Automated Tests:
- src/app/manifest.test.ts: passed
- src/services/install-prompt-service.test.ts: passed
- src/services/engagement-tracker.test.ts: passed
Linting: 1 error found (noted above).

Recommendations

Fix Lint Error: Add a global type declaration for navigator.standalone to remove the any cast.
Engagement Optimization: Currently polling EngagementTracker every 5 seconds. Ideally, this should react to DB changes, but polling is acceptable for MVP.

Conclusion

The story is READY TO MERGE / COMPLETE. The minor lint issue does not block functionality or stability.
