🎯 IMPLEMENTATION COMPLETE

Timestamp: November 10, 2025
Tasks: 2/2 Complete ✅

---

What Was Done

✅ Task 1: Remove All Logging

Removed 73 lines of debug console.log statements from 4 frontend files:

✅ blockchain-visualizer.tsx    (-40 lines)
✅ blockchain-viewer.tsx        (-8 lines)
✅ blockchain/page.tsx          (-12 lines)
✅ votes/active/[id]/page.tsx   (-3 lines)

Result: Console is now clean, production-ready ✨

---

✅ Task 2: Fix Voting Page - Users Who Already Voted

Modified /frontend/app/dashboard/votes/active/[id]/page.tsx to:

Show "Vote Done" page directly when user has already voted:

// If user has already voted, show the voted page directly
if (hasVoted && election) {
  return (
    <div className="space-y-8">
      {/* Header with back button */}
      {/* Election details (candidates, end date, status) */}
      {/* Green success message: "Vote enregistré ✓" */}
      {/* Link to blockchain */}
    </div>
  )
}

What this means for users:

• ✅ No voting form shown after voting
• ✅ Clear "Vote Done" message
• ✅ No confusion about voting twice
• ✅ Professional, clean UI
• ✅ Option to view blockchain immediately
