Walkthrough

The PR enhances hackathon registration and analytics tracking by introducing service-role Supabase clients to bypass RLS for admin updates on registration and click/view counts, adding comprehensive analytics tracking for hackathon registrations, improving the dashboard to display combined event and hackathon statistics, and strengthening registration state management with defensive error handling and detailed logging.

Changes

Cohort / File(s)	Summary
Hackathon API routes app/api/hackathons/[id]/register/route.ts, app/api/hackathons/[id]/track-click/route.ts, app/api/hackathons/[id]/track-view/route.ts	Updated POST/DELETE handlers to use service-role Supabase client for bypassing RLS; added logging and error handling; introduced updated_at timestamp tracking; POST parameter renamed from request to _request; register route now uses masterRegistrationsService for unregistration with fallback logic and integrates analytics tracking for registrations
Hackathon page app/hackathons/[id]/page.tsx	Enhanced registration status checking with explicit false initialization on missing auth; improved error parsing and state management in handleRegister and handleUnregister; replaced hard page reload with URL reload; added defensive error handling across registration flows
Company dashboard components/dashboard/CompanyDashboard.tsx	Added hackathons data fetch with approval filtering; computes combined registrations total from both events and hackathons; updates totalHackathons from company field to approvedHackathons length; replaces totalRegistrations source with combined calculation
Analytics service lib/services/analytics-service.ts	Added new public static method trackHackathonRegistration(hackathonId: string) that fetches hackathon, retrieves associated company, and increments company's total_registrations analytics

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

• app/api/hackathons/[id]/register/route.ts: Service-role client introduction and integration with masterRegistrationsService, analytics tracking, and count updates require careful review to ensure RLS bypass is safe and error handling is comprehensive.
• components/dashboard/CompanyDashboard.tsx: Data aggregation logic combining events and hackathons registrations needs verification for correctness; ensure filtering and calculation logic is sound.
• State management in app/hackathons/[id]/page.tsx: Verify that the registration state updates correctly on both success and error paths, and that URL reload doesn't cause unintended side effects.

• Fix/companyhackathons — Improve Hackathon Tracking & Add Registration Endpoints #339: Directly modifies the same hackathon API routes (register/route.ts, track-click/route.ts, track-view/route.ts) and page-level registration handlers, updating registration and tracking logic.
• Feature/zenith hall transformation #231: Introduces and exposes the masterRegistrationsService that is now used by the register route for unregistration with service-based abstraction.
• feat(company-profile): Add null safety and update registration metrics display #335: Modifies the total_registrations metric on the company analytics, which this PR now updates via the new trackHackathonRegistration method.

Poem

🐰✨ A hop through the code, with clients so grand,
Service-role admins now bypass the land,
Registrations tracked, dashboards aligned,
Click counts and views left in time's bind,
Analytics bloom—the hackathon's designed! 🎉
