Can I vibe code Conductrics?

Build a lightweight server-side and client-side web experimentation engine in Node.js, TypeScript, PostgreSQL, and Redis to replace Conductrics core features.

1. DATA MODEL & SCHEMA
- Create database tables: `experiments` (id, key, status, traffic_allocation, dynamic_weighting_enabled), `variants` (id, experiment_id, key, payload_json, weight), `assignments` (visitor_id, experiment_id, variant_id, assigned_at), and `events` (id, visitor_id, experiment_id, variant_id, event_type, value, created_at).
- Index assignments by `(visitor_id, experiment_id)` for quick lookup.

2. DECISION ENGINE & BANDIT LOGIC
- Implement a deterministic hashing assignment algorithm (using MurmurHash3 on `visitor_id + experiment_key`) for stable 50/50 or custom split distributions.
- Implement a Multi-Armed Bandit background worker using Thompson Sampling (Beta-Binomial distribution based on conversions vs. impressions) that recalculates variant weights every hour if `dynamic_weighting_enabled` is true.
- Store active variant weights in Redis for low-latency lookup (<5ms response time).

3. API ENDPOINTS & INTEGRATION
- Endpoint `POST /api/v1/decide`: Accepts `visitorId`, `experimentKeys` array, and optional `context` (user-agent, referrer). Returns assigned variants and payload JSON.
- Endpoint `POST /api/v1/track`: Accepts `visitorId`, `eventName`, `value`, and optional metadata. Matches events to active assignments and asynchronously logs to PostgreSQL.

4. CLIENT SNIPPET & EDGE EXECUTION
- Write a minimal sync JavaScript snippet (<3kb) that blocks DOM rendering using critical CSS (`body { visibility: hidden }`) until decision payloads return or a 100ms timeout expires, preventing Cumulative Layout Shift.
- Support DOM modification instructions (e.g., querySelector replacement, class toggles, or direct redirect).

5. FAILURE MODES & OUT OF SCOPE
- Fallback: If Redis or API times out, serve control variant immediately without erroring.
- Deduplication: Ensure duplicate conversion tracking for the same visitor session is ignored or flagged.
- Out of scope: Visual drag-and-drop web builder UI, complex multi-touch attribution models, and native mobile SDKs.
