Implement Multi-Winner Milestone-Based Bounty Flow

[0xdevcollins]

Feature: Implement Multi-Winner Milestone-Based Bounty Flow

Overview

The Multi-Winner model (Model 4) splits large bounties into milestones, each supporting multiple parallel winners with a natural funnel progression. This is the most complex claiming model and is entirely unimplemented on the frontend.

Depends on: #139 (TypeScript contract bindings)

---

Goals

• Display milestone funnel structure (e.g., 6 → 3 → 1 winners)
• Allow contributors to apply for specific milestone slots
• Track parallel work across multiple contributors
• Support advancement criteria (top N performers move forward)
• Per-milestone payment via escrow release

---

Implementation Details

1. Milestone Funnel Visualization

Create: components/bounty/milestone-funnel.tsx

• Visual funnel showing milestone stages
• Per-stage: slot count, payout per winner, advancement criteria
• Active stage highlighted
• Completed stages show winners

2. Multi-Winner Application

Create: components/bounty/multi-winner-apply.tsx

• Show available slots per milestone
• Assignment method display (geographic, component, language, topical)
• Apply for specific slot with proposal

3. Milestone Progress Tracking

Create: components/bounty/milestone-progress-tracker.tsx

• Track all contributors working in parallel
• Per-contributor: status, submission, score
• Advancement decisions displayed after review

4. Creator Management Dashboard

Create: components/bounty/multi-winner-management.tsx

• Review all submissions per milestone
• Score/rate each submission
• Select who advances to next milestone
• Handle dropouts and slot reassignment

I am applying to implement the Multi-Winner funnel progression (Model 4), focusing on the complex transition from parallel contributors to final winners. My approach involves building a comprehensive suite of components including the Milestone Funnel visualization and a Creator Management Dashboard to track slot assignments, scoring, and advancement criteria across multiple stages. I will ensure the hooks and components seamlessly integrate with the #139 contract bindings to handle per-milestone escrow releases and dropout reassignments.
