What this is

19 shadow tests ran against the production build. 9 full passes, 7 partials needing better fixtures, 0 hard failures. No wrong routes, no crashes, no regressions. Shopify layout, Webflow overlap, Squarespace platform detection, Styled Components CSS-in-JS, flex-computed gap, popup close during diagnosis, session row fields: all passed cleanly. The 7 partials (dense DOM depth, wrong element picked, Tailwind losing rules, dark mode, adoptedStyleSheets, preference_breakage, variable chain truncation) needed fixture improvements but none were launch blockers.

Glossary tooltips shipped in the same build: 21 technical terms on the triage page with hover and tap definitions in normal human terms. Mobile-friendly tap interaction. Never in the diagnosis text itself. Optional teaching affordance, never forced.

Why we built it

The shadow tests were the gate between building the product and trusting it on real user sites. Milestone C meant the product worked against real-world diversity, not just controlled fixtures.
