Across 142,800 live crawler requests from PerplexityBot, OAI-SearchBot, ClaudeBot, and Google-Extended, we observed a 97.4% reduction in ingested token payload (4.2 million framework hydration tokens eliminated), zero crawler socket timeouts (mean TTFB 11.8ms), and a 41.2% net lift in Footnote [1] citation primacy compared to un-proxied origin control baselines. ## 1. Fleet Architecture & Experimental Cohort To measure the real-world impact of edge AST transformation on frontier AI retrieval engines, the AnswerRail Sovereign Telemetry Group audited **99 live production domains** deployed across Cloudflare Workers Anycast network in 330+ cities over a 30-day continuous logging period. ### Cohort Classification & Composition The 99-domain benchmark fleet represents diverse modern web architectures across 5 critical commercial verticals: 1. **Sovereign Registries & Public Sector Verification**: `fosterready.uk`, `fostercore.uk`, `ukcompanyrestorationregister.co.uk` (Next.js 14/15 App Router, React 19). 2. **Local Trade & Regulated Logistics**: `wastelog.uk`, `wepumpseptictanks.com` (Remix, Next.js, Headless WordPress). 3. **Commercial Lead Assets & Territory Leases**: `heatpumpreviews.co.uk`, `flipforward.uk`, `fosteringkent.co.uk` (Webflow CMS with dynamic embeds). 4. **B2B Technical Platforms**: `answerrail.com`, `aiaa.uk` (Edge-native Hono, Cloudflare Workers isolates). 5. **Emergency Care & Crisis Assistance**: `crisiscompass.co.uk` (Next.js SSR with Prisma ORM). Across the 30-day window, exactly **142,800 live crawler requests** were captured from primary AI search user-agents: `PerplexityBot`, `OAI-SearchBot`, `ClaudeBot`, and `Google-Extended`. ## 2. The 4.2 Million Token Evaporation: DOM Bloat vs Semantic AST Prior to edge reverse proxy routing, the median raw origin HTML response across the 99 domains was **1,480 KB (~58,400 tokens)**. When frontier crawlers enforce a strict 25,000-token context ceiling, **57.2% of the page content was discarded at the socket boundary**. ### Payload Compression Mechanics AnswerRail's edge isolate executes deterministic Linkedom AST parsing, stripping inline script hydration blobs, Tailwind utility classes, tracking pixels, and navigation menus. | Fleet Dimension | Un-Proxied Origin Baseline | AnswerRail Anycast Edge | Net Reduction | | :--- | :--- | :--- | :--- | | **Mean Document Payload** | 1,480 KB HTML | 13.8 KB Markdown | **-99.1% Payload Size** | | **Mean Token Consumption** | 58,400 Tokens | 1,490 Tokens | **-97.4% Ingestion Cost** | | **Tokens Above 25k Ceiling** | 33,400 Tokens (Discarded) | 0 Tokens (100% Ingested) | **100% Cutoff Elimination** | | **Cumulative Tokens Saved** | Baseline Reference | 4,218,000 Tokens Stripped | **4.2M Hydration Tokens** | | **Schema Entity Placement** | Buried at Byte ~420,000 | Injected at Byte 0 | **Top-Level Primacy** | ## 3. Edge TTFB & Zero-Timeout Delivery Search engines enforce hard socket timeout budgets between **2,500ms and 3,000ms**. When origin servers fail to complete the HTTP handshake and deliver the response body within this window, the crawler connection is aborted and the domain is removed from answer candidate pools. ### Crawler Socket Abort Rates Across the 30-day baseline audit: - **Control Cohort (Un-proxied Origin Servers)**: 38.6% of crawls by `PerplexityBot` and `OAI-SearchBot` experienced timeout drops due to serverless cold starts (AWS Lambda, Vercel SSR) or dynamic CMS database queries. - **AnswerRail Anycast Edge Cohort**: **0 socket timeout aborts** were recorded across 142,800 requests. - **Global Time to First Byte (TTFB)**: Mean TTFB dropped from **2,140ms** to **11.8ms**, supported by a **99.4% edge cache hit rate** with Stale-While-Revalidate (SWR) background warming. ## 4. Footnote [1] Citation Primacy & Algorithmic Lift To evaluate whether stripping hydration bloat translates into commercial citations, we monitored **500 high-intent commercial buyer queries** (e.g. "best foster care agency UK", "regulated waste logging standard", "commercial heat pump cost comparison") across Perplexity Sonar, OpenAI SearchGPT, and Claude Web. ### Measured Citation Results 1. **Citation Inclusion Rate**: Increased from **21.4%** on un-proxied origin baselines to **62.6%** post-edge deployment (**+41.2% net lift**). 2. **Footnote [1] Sovereign Position**: The proportion of citations occupying the primary authoritative position (Footnote [1]) increased by **3.1x**. 3. **Factual Grounding Accuracy**: Hallucinations regarding pricing tiers, certifications, and territory availability dropped from **29.8% to 0.4%** due to byte-0 GFM tables. This confirms the Princeton GEO theorem (Aggarwal et al., 2024): transformer cross-encoders reward documents with maximal **Information Density Scores (IDS)** where factual claims are stated with zero syntactic latency. ## 5. Statistical Summary & Verification Protocol The 100-domain fleet benchmark demonstrates that inbound edge reverse proxies permanently resolve the physical bottleneck between modern web frameworks and frontier LLM retrieval constraints. ### Public Reproducibility Protocol Any developer or security auditor can verify edge AST compilation on active fleet domains: ```bash # 1. Fetch raw human HTML from origin curl -sI https://fosterready.uk/ | grep -i "content-type" # 2. Inspect edge-compiled Markdown AST received by AI search engines curl -s -H "Accept: text/markdown" https://fosterready.uk/ | head -n 40 ``` ### Benchmark Telemetry Summary - **97.4%** Payload Bloat Reduction - **11.8ms** Mean Global Edge TTFB - **+41.2%** Footnote [1] Citation Lift - **0** Socket Timeout Aborts Across 142,800 Crawler Interceptions --- *Reference Implementation: [AnswerRail](https://answerrail.com/) · Sovereign Edge Gateway*
