## Core Problem Solved
Legacy human usability platforms (`UserTesting.com`, `Maze`, `Lookback`) cost £15,000–£30,000/year, waste 85% of tester time on mechanical form boilerplate, and deliver 30-minute videos that engineering teams rarely watch with zero code fixes. Conversely, pure headless scripts (`Playwright`, `Lighthouse`) check DOM selectors but miss emotional trust leaks, premature phone-number gates, and UK vs. US dialect collisions (`Zip Code` vs `Postcode`, `Color` vs `Colour`).

## The Kasparov Centaur Architecture
1. **0.5s AI Exosuit Pre-Flight**: Automatically navigates staging/production URLs, injects realistic persona data, maps interactive DOM bounding boxes via Set-of-Marks (SoM), and checks WCAG 2.1 AA accessibility, horizontal mobile overflow (`390px`), and UK/US localization.
2. **25-Persona Monte Carlo Swarm**: Simulates diverse cognitive profiles (skeptical buyers, screen-reader users, time-poor mobile commuters, enterprise compliance officers) to pinpoint conversion drop-off choke points.
3. **4-Minute Human Voice Intuition**: Vetted UK human pilots ("Digital Centaurs") drop directly into the critical conversion step for 4 minutes of high-signal voice think-aloud feedback—earning £7.50 per 4-minute mission (£50–£60/hr effective rate).
4. **Self-Healing Git Pull Request Diffs**: Converts verified accessibility, layout, and conversion defects directly into reviewable HTML/CSS/TypeScript Git Pull Request diffs.

## Transparent Pricing (GBP)
- **Free Live Scan (£0)**: Instant Edge HTTP, DOM X-Ray, WCAG 2.1 AA label check, UK/US dialect audit, and SUS score at `https://centauruxr.com/app?target=<url>&autorun=1`.
- **Single Audit Sprint (£49 one-off)**: 10 Synthetic AI Persona Runs + 2 Vetted UK Human Centaur 4-minute voice missions + SUS Report + Auto-Synthesized Git PR Diffs.
- **Standard Continuous (£149/mo)**: Weekly automated funnel audits, 25-persona Monte Carlo swarm simulations, 5 human Centaur sessions/month, UK/US dialect guardrails.
- **Pro Swarm & CI/CD (£499/mo)**: Unlimited CI/CD GitHub Action PR gates, 20 human Centaur sessions/month, multi-viewport regression oracle.
- **Enterprise Dedicated Fleet (Custom)**: Custom demographic guild recruitment, private staging proxy tunnel, SLA support.

## API & CI/CD Integration
