Can I vibe code Trustpilot?

Build an open-source, self-hosted product and store review system designed for Shopify and custom storefronts.

DATA MODEL (PostgreSQL Prisma schema):
- Organization: id, name, primary_domain, created_at
- Order: id, org_id, external_order_id, customer_email, customer_name, store_platform, fulfilled_at, status
- ReviewInvitation: id, order_id, token (unique, cryptographically secure), status (pending, sent, responded, expired), scheduled_for, sent_at
- Review: id, org_id, order_id, rating (1-5 integer), reviewer_name, reviewer_email, title, body, status (pending, published, flagged, rejected), verified_buyer (boolean), product_id (nullable for general store review), created_at
- ReviewResponse: id, review_id, responder_user_id, body, created_at

CORE FLOWS:
1. Webhooks & Automations:
   - Webhook ingest endpoint POST /api/webhooks/order-fulfilled (supports Shopify, WooCommerce HMAC signatures).
   - Stores Order record and queues a ReviewInvitation scheduled for N days post-fulfillment (configurable default: 7 days).
   - Background worker (BullMQ/Redis) processes due invitations and dispatches transactional emails using Resend or Postmark API containing unique token links.

2. Review Submission (Public):
   - GET /review/:token validates token, renders clean review submission form.
   - POST /api/reviews accepts rating, title, body, optional product_id. Sets verified_buyer=true automatically based on token linkage. Invalidate token immediately upon submission.

3. Embeddable Web Component Widgets:
   - Build a lightweight (<15kb gzipped) Shadow DOM web component (<store-review-badge org-id="..." widget-type="carousel|grid|badge">).
   - Serve static HTML/JS from edge CDN endpoint GET /api/v1/widgets/data.
   - Include auto-generated Schema.org AggregateRating JSON-LD script tag inside component output for SEO rich snippets.

4. Merchant Admin Dashboard (Next.js App Router, Tailwind, Shadcn):
   - Analytics overview: Average TrustScore (weighted 1-5 rating formula), response rates, total reviews over time.
   - Moderation queue: List, filter (by status/rating), publish, reject, respond to customer reviews.
   - Email template builder with preview.

FAILURE MODES & EDGE CASES TO HANDLE:
- Rate limit submission endpoints by IP and token to block review spam.
- Handle unsubscribe/opt-out requests gracefully in ReviewInvitation flows.
- Strict XSS sanitization on review body and merchant response text.

OUT OF SCOPE:
- Syncing reviews to Google Seller Ratings (requires official Google partnership).
- Public consumer marketplace destination directory.
- Built-in photo/video media hosting transformations (store simple text reviews for MVP).
