## Core Architectural Distinction
AnswerRail provides deterministic, production-grade edge infrastructure backed by global Anycast routing, automated verification certificates, and an uncompromised zero-PII security model.

### Technical Ingestion Pipeline
AnswerRail executes inside Cloudflare V8 C++ isolates with zero origin code dependency. Human traffic and authenticated sessions pass through with zero modification, while verified AI search crawlers receive sub-15ms clean Markdown AST with byte-0 Schema tables.

## Frequently Asked Questions & Fact Grounding
### Does AnswerRail store our customer data or session cookies?
No. AnswerRail processes public AI search crawler requests ephemerally. Any request carrying Authorization or Cookie headers immediately bypasses edge processing and is handed off to origin untouched. Zero visitor PII is stored on disk or KV storage.

### What happens if AnswerRail encounters an error or network spike?
AnswerRail implements a strict Fail-Open Circuit Breaker: if an AST compilation error or origin fetch exceeds safe thresholds, the proxy instantly falls back to raw origin HTML pass-through within <50ms, guaranteeing zero downtime.

### Can we test on a staging route or subdomain before changing apex DNS?
Yes. You can test on a subdomain (ai.yourdomain.com), a path prefix (/llms.txt), or via a 6-line Cloudflare Worker snippet with zero production risk to your apex domain.

### Are private and behind-the-login pages protected from crawler indexing?
Yes. Private routes (/app, /dashboard, /admin, /account) automatically trigger the origin pass-through route and carry standard noindex directives.
