Feature 5: Vendor Reputation System with Reviews & Verification

[saidai-bhuvanesh]

Description

This issue aims to build a community-driven trust marketplace by implementing a Vendor Reputation System with reviews and rating verification.

We will add a rating and review system where verified customers can rate vendors (1 to 5 stars) and write textual reviews. A Supabase table public.vendor_reviews will be created, and triggers will automatically update a vendor's overall trust_score and avg_freshness_score based on both their reviews and scans. A glowing "Trusted Vendor" badge will be displayed on the map and leaderboard for vendors with high reputation scores. We will also include basic fake review detection to maintain system integrity.

Technical Implementation Details

1. Database Schema: Add public.vendor_reviews and trigger functions in database migrations.
2. Review API: Build backend routes under backend/vendors.py to manage adding/listing reviews.
3. Badges & Visuals: Compute and render the "Trusted Vendor" badge on map popups and leaderboards.
4. Reviews Section: Construct a custom reviews and rating submit card within the vendor detail drawer on the map.

Hi @jpdevhub! I'd love to build this as part of SSoC 2026 👋

My Approach:

• Design and implement the public.vendor_reviews Supabase table with triggers to auto-update trust_score and avg_freshness_score
• Build backend routes under backend/vendors.py for adding and listing reviews with verified customer checks
• Render a "Trusted Vendor" glowing badge on map popups and leaderboards for high-reputation vendors
• Add a review submission card in the vendor detail drawer with star rating (1–5) and text input
• Implement basic fake review detection (rate limiting, flagging duplicate IPs/accounts)

Could you please assign this to me (@arcgod-design)? Thank you!
