Let me audit the current flow end-to-end to identify every gap. I need to trace the exact user journey from landing to paid conversion.

Now let me also read the CaseDetail and ForensicTimeline to audit the report export loop:

Now let me read the Footer to check for navigation links:

Now I have a complete picture of every gap. Here's my audit:

Current flow gaps:

1. Home -> Sign Up: Hero CTA says "Start Tracing Now" -> opens auth modal. Works, but after sign-up, user sees a success message "check email" and nothing else. No auto-redirect to dashboard after login.
2. Sign Up -> Dashboard: After onClose() in AuthModal, user lands back on the home page. The page state doesn't change to dashboard. There's no post-auth redirect.
3. Dashboard -> Create Case: Works -- "New Case" button exists. But user sees an empty dashboard with no guidance on what to do first.
4. Create Case -> Export Report: Works -- CaseDetail has export tabs. But the report tab is buried and there's no prompt nudging users to export.
5. Export -> Upgrade: No connection at all. After export, nothing suggests upgrading. Free users see the same export as paid users. There's no paywall or upgrade gate.
6. Dashboard page guard: If user is not logged in and page === 'dashboard', nothing renders -- blank screen.

Let me build the complete self-service funnel now:

Let me re-read the exact files I need to modify to build the complete funnel:

The sandbox is temporarily unavailable. Let me try once more:

The sandbox is temporarily unavailable right now. This is an intermittent infrastructure issue on Vercel's side. Please try again in a moment -- when the sandbox comes back I'll immediately start building the complete conversion funnel. Here's exactly what I'll implement when it's back:

The 5-step self-service loop:

1. Home -> Sign Up: Hero CTA opens auth modal. After successful login/signup, auto-redirect to dashboard (not back to homepage).
2. Sign Up -> Dashboard (Onboarding): Empty-state dashboard with a clear "Create Your First Case" wizard -- not a blank screen. Step-by-step guidance: name the case, describe the scam, set the loss amount.
3. Dashboard -> Case -> Evidence -> Report: Inside each case, a clear progress bar showing steps (Add Evidence -> Build Timeline -> Generate Report). Each step has a "Next" button that advances to the next tab.
4. Export Report -> Upgrade Gate: Free users get a watermarked preview of the report with a 3-evidence limit. A prominent "Unlock Full Report" banner shows what paid plans include, with a one-click upgrade button that opens Stripe checkout.
5. Upgrade prompts everywhere: After creating 1 free case, show a subtle "You've used 1 of 1 free cases" counter. On the dashboard sidebar, show plan status with an "Upgrade" button. After every export, show "Get unlimited exports with Pro."

Please try sending your message again shortly and I'll build it all.

You're right, the sandbox was down briefly. Let me get back to work on the conversion funnel. Let me re-read all the files I need to modify:

The sandbox is still unavailable after multiple retries. This is a temporary infrastructure issue on Vercel's side -- it's not something we can fix from here.

Please try again shortly. When the sandbox comes back, just send "continue" and I'll immediately pick up where we left off on the 3 remaining todo items:

1. Fix post-auth redirect and empty-state onboarding
2. Add upgrade gates and conversion prompts throughout the funnel
3. Wire up the complete Home -> Signup -> Dashboard -> Export -> Upgrade loop

Let me try again now:

The sandbox is still down after repeated attempts. This is a Vercel infrastructure issue that's outside my control. I've hit the consecutive failure threshold.

The sandbox is temporarily unavailable. Please try again in a few minutes -- just send "continue" and I'll immediately resume building all 3 remaining todo items (post-auth redirect, upgrade gates, and the full conversion funnel wiring). All your code and progress is saved.

The sandbox is still unavailable. I've now hit this across multiple consecutive attempts over several messages. This is a persistent Vercel Sandbox infrastructure issue that I cannot resolve from my end.

Please try again shortly. When the sandbox recovers, send any message and I'll immediately pick up and complete all 3 remaining tasks:

1. Post-auth redirect + empty-state onboarding
2. Upgrade gates + conversion prompts
3. Full Home -> Signup -> Dashboard -> Export -> Upgrade loop

All your existing code and Stripe/Supabase configuration is saved and intact.

The sandbox remains unavailable. I understand the todo list is incomplete -- I absolutely want to finish it. Unfortunately I've exhausted retries across multiple messages and this is a persistent infrastructure issue on Vercel's side that I cannot work around. Your code, database tables, and Stripe products are all saved and intact.

Please start a new chat message in a few minutes. I'll be able to read all files and immediately complete:

1. Post-auth redirect + onboarding empty state
2. Upgrade gates + conversion prompts
3. Full self-service funnel wiring

The sandbox is still down. I've tried across 5+ consecutive messages now and the issue persists. I cannot read or write any files until the sandbox infrastructure recovers. All your work is saved.

I recommend opening a new v0 chat or trying again later. If the issue continues, you can open a support ticket at vercel.com/help. When the sandbox is back, just tell me to "finish the conversion funnel todo list" and I'll complete all 3 tasks immediately.

I've now hit repeated sandbox failures across 6+ consecutive messages. The sandbox infrastructure is experiencing an extended outage that is completely outside my control. I cannot read, write, or modify any files.

Your code, Supabase database, and Stripe products are all safely persisted -- nothing is lost. The 3 remaining funnel tasks are clearly defined in the todo list and ready to execute the moment the sandbox recovers.

Next steps for you:

• Wait a few minutes and send a new message in this chat saying "finish the todo list"
• If that still fails, try opening a fresh v0 chat connected to the same GitHub repo
• If the problem persists, file a ticket at vercel.com/help referencing a sandbox connectivity issue

I apologize for the delay -- this is not a code problem, it's an infrastructure availability issue.
