Data Flow — RESOLVE FLOW

1. User (thread author or admin) clicks "Resolve Market"
2. Frontend: Prompts wallet → calls Governor.resolve()
3. No immediate API call — EVM worker picks up event
4. EVM Worker (120s polling) detects ProposalResolved event
5. Event mapper → Outbox → RabbitMQ
6. ProjectResolution command → DB update (status=resolved, winner set)
7. React Query refetch → card shows winner and enables redeem tab

Permission Gating

• Modal only visible to thread author or community admin
• "Resolve Market" button only enabled after end_time has passed
• Use useTopicGating for permission checks
