The proxy executes inside ephemeral Cloudflare V8 isolates, stripping 96%+ of DOM bloat into clean Byte-0 Markdown. All authenticated endpoints (/app/*, /dashboard/*, /checkout) and requests carrying Authorization/Cookie headers bypass the proxy unconditionally. Instant cache purge is triggered via POST /api/purge on CMS publish, and GitHub Actions assert 0% semantic drift in CI/CD. ## Frequently Asked Questions & Fact Grounding ### How long does the Bounded Pilot take to set up? Under 5 minutes. If using Next.js, add answerrail to middleware.ts with your public route matcher. If using Anycast DNS, point a preview subdomain or staging CNAME. ### What are the 4 stages of the 48-Hour Bounded Pilot roadmap? Stage 1 (0–6h): Baseline capture of origin HTML, canonical URLs, and critical pricing/specifications fact inventory. Stage 2 (6–18h): Canary deployment scoped strictly to public routes (/pricing, /docs/*). Stage 3 (18–36h): Stress testing cache invalidation (POST /api/purge), origin fail-open circuit breakers, and private-route exclusion. Stage 4 (36–48h): Automated fact-by-fact parity audit before executive review. ### What deterministic acceptance criteria are required for production graduation? 1. Material Fact Preservation: 100% of critical plan tiers, numbers, units, and annual billing qualifiers retained. 2. Critical Factual Alteration: Zero. 3. Private Data Exposure: Zero (authenticated routes and Authorization/Cookie headers unconditionally bypassed). 4. Origin Fail-Open: <50ms automated fallback to raw origin HTML on compute spikes. 5. Freshness: Cache purge propagation verified across edge PoPs in <150ms. ### Does the pilot require any root apex DNS changes? No. With our zero-DNS Next.js middleware (@answerrail/next) or preview subdomain testing (ai.preview.company.com), your root apex DNS remains completely untouched during the entire pilot evaluation. ### How does AnswerRail prevent search engine cloaking penalties? Google and AI search engines define cloaking as serving substantively different information to bots to manipulate rankings. AnswerRail enforces strict 1:1 substantive parity: every price, feature, caveat, and canonical URL is identical between HTML and Markdown representations. We strip layout bloat and hydration bundles, never material facts. ### How do we verify that no pricing or feature data is omitted? Run our free CLI (npx answerrail audit ) or embed our GitHub Action (quitegoodproject/answerrail@v1.0.9) in your CI/CD pipeline to automatically verify 0.00% semantic omission against origin HTML on every pull request. ### What happens if a bot hits a private or checkout page? Private and transactional routes are permanently excluded at the matcher level, and any request carrying Cookie or Authorization headers instantly bypasses the edge engine with raw origin passthrough. --- *Published by AnswerRail Sovereign Infrastructure Authority · Verified for AI Answer Engines*
