+# Pulse Polish Audit
+
+**Date:** 2026-03-16
+**Version:** 0.15.0-alpha
+
+## Current State
+
+Pulse is a mature product — 55+ routes, 156 API handlers, 50 migrations, 8 background workers, 3 third-party integrations. The codebase is clean with zero TODO/FIXME comments. Recent work has focused on UX refinements: empty state CTAs, animated number transitions, inline bar charts, and mobile responsiveness fixes.
+
+## Polish Opportunities
+
+### High Impact
+
+#### ~~1. Custom 404 Page~~ ✅ Already Done
+- Branded 404 page exists at `app/not-found.tsx` with "Go back home" and "View FAQ" CTAs
+
+#### 2. Rate Limit (429) UX Feedback
+- **Issue:** When rate limited, API requests fail silently with no user feedback
+- **Effort:** Low
+- **Action:** Catch 429 responses in the API client and show a toast with retry timing (`Retry-After` header)
+
+### Medium Impact
+
+#### 3. Export Progress Indicator
+- **Issue:** PDF/Excel exports have no progress bar and can appear frozen on large datasets
+- **Effort:** Low
+- **Action:** Add a determinate or indeterminate progress bar inside `ExportModal.tsx`
+
+#### 4. Filter Application Feedback
+- **Issue:** Applying filters has no loading/transition indicator
+- **Effort:** Low
+- **Action:** Show a subtle loading state on the dashboard when filters change and data is refetching
+
+#### 5. Inline Form Validation
+- **Issue:** All validation errors go to toasts only; no inline field-level error messages
+- **Effort:** Medium
+- **Action:** Add inline error messages below form fields (funnel creation, goal creation, site settings)
+
+#### 6. Accessibility: Modal Focus Trapping
+- **Issue:** Modals don't trap focus, breaking keyboard-only navigation
+- **Effort:** Medium
+- **Action:** Implement focus trapping in modal components (VerificationModal, ExportModal, settings modals)
+
+#### 7. Accessibility: ARIA Live Regions
+- **Issue:** Real-time visitor count updates aren't announced to screen readers
+- **Effort:** Low
+- **Action:** Add `aria-live="polite"` to `RealtimeVisitors.tsx` and other auto-updating elements
+
+#### 8. Table Pagination Loading
+- **Issue:** No loading indicator when paginating through table data
+- **Effort:** Low
+- **Action:** Show a loading spinner or skeleton overlay when fetching the next page of results
+
+### Low Impact
+
+#### 9. Remove Unused `axios` Dependency
+- **Issue:** `apiRequest` is the actual HTTP client; `axios` is dead weight in the bundle
+- **Effort:** Trivial
+- **Action:** `npm uninstall axios` and verify no imports reference it
+
+#### 10. PWA Service Worker Caching
+- **Issue:** `@ducanh2912/next-pwa` is configured but no offline caching strategy exists
+- **Effort:** Medium
+- **Action:** Define a caching strategy for static assets and API responses, or remove the PWA dependency
+
+#### 11. Image Lazy Loading
+- **Issue:** Table/list images (favicons, flags) don't use `loading="lazy"`
+- **Effort:** Low
+- **Action:** Add `loading="lazy"` to images in referrer lists, country tables, and similar components
+
+#### 12. OpenAPI Specification
+- **Issue:** Backend has no Swagger/OpenAPI doc; README serves as the only API documentation
+- **Effort:** High
+- **Action:** Generate an OpenAPI spec from Go handler annotations or write one manually
+
+## Additional Notes
+
+- **No i18n** — English only. Worth planning if expanding to international markets.
+- **Test coverage** — 16 backend test files cover core logic well, but GSC/BunnyCDN sync and report delivery e2e are gaps.
+- **Chart.tsx is 35KB** — A candidate for splitting into sub-components eventually.
