## Core Architectural Distinction
Buyers no longer need to pay $250–$500/mo for Scrunch AI passive monitoring plus $20,000+/yr for an enterprise HTML proxy. AnswerRail unifies 6-Engine AI Visibility & Share-of-Voice analytics, Third-Party Citation Source Gap tracking, GA4 Google AI Overviews (udm=50) + 120s Dark-AI attribution, AND <15ms Byte-0 Linkedom AST Markdown compilation with a 100% FactCheck price recall shield in one $99/mo self-serve platform.

### Technical Ingestion Pipeline
Scrunch AXP sits at the CDN layer to serve a sanitized, streamlined HTML DOM to AI crawlers, integrated with Sitecore’s digital experience platform. In contrast, AnswerRail executes inside Cloudflare Workers V8 isolates using Linkedom (JavaScript DOM parser) across 330+ Anycast PoPs. It converts origin DOM into clean GFM Markdown, eliminating HTML tag overhead. AnswerRail places Schema.org entity graphs as top-level GFM tables within the first 1,500 tokens (aligning with positional primacy findings in Liu et al., TACL 2024, "Lost in the Middle"), verifies 100% static currency/FAQ/link recall via extractIndependentStaticReference, signs payloads with asymmetric Ed25519 RFC 9421 cryptographic provenance (kid="ar_ed25519_2026_k1"), and dispatches IndexNow pings to Bing/SearchGPT.

## Verifiable Engineering & Cryptographic Specification (`v1.1.0-parity-v20`)

### 1. Fail-Closed Representation Parity Gates vs. Fail-Open Origin Fallback
AnswerRail enforces a strict architectural separation between **representation correctness (fail-closed)** and **request availability (fail-open to origin)**:
- **Converter-Independent Static Reference Extractor (`extractIndependentStaticReference` in `src/core/transformer.ts`)**: Operates directly on raw origin HTML without using Linkedom or Turndown. It strips non-visible blocks (`<head>`, `<script>`, `<style>`, `<template>`, `<noscript>`, `<svg>`, `display:none`, `.opacity-0`), extracts collapsed FAQ/accordion answers (`<div hidden>`, `role="region"`, `<details>`, `<dd>`), extracts main-content links (`<article>` / `<main>`), collapses split inline currency spans (`<span>$</span><span>20</span>` -> `$20`), and decodes HTML currency entities (`&#36;49` -> `$49`).
- **Exact Boundary Matching**: Currency tokens use regex word/digit boundaries (`(?:^|[^\d])...(?<!\d)`) so dropping `$20` is never masked by `$200` in the same document. Dynamic client-side controls (`role="tablist"`, `input[type="range"]`) are explicitly flagged in YAML frontmatter (`omitted_dynamic_states: ["non_default_tab_panels", "volume_slider_tiers"]`).
- **Fail-Closed Representation Policy & Runtime Timeouts**: If `currencyRecallRatio < 1.0`, `faqAnswerRecallRatio < 1.0`, `linkRecallRatio < 1.0`, or raw origin HTML exceeds the `2,097,152`-byte (`2 MiB`) streaming cap (`truncated: true`), the **Markdown representation fails closed**: it is rejected, never cached (`X-AnswerRail-Cache: BYPASS`), and never emitted. Outbound origin fetches enforce a `10,000ms` abort timeout in `src/core/fetcher.ts`, and `answerrail/next` middleware enforces a configurable `timeoutMs` (default `3,500ms`).
- **Unified Fallback Diagnostics Header Contract (`src/routes/live-proxy.ts`)**: Whenever a parity gate or `2 MiB` truncation check blocks a Markdown transform, the proxy **fails open to unmodified raw origin HTML** with the exact canonical 5-header set:
  - `Cache-Control: no-store, no-cache, must-revalidate`
  - `X-AnswerRail-Cache: BYPASS`
  - `X-AnswerRail-Failsafe: FAIL_CLOSED_ORIGIN_HTML`
  - `X-AnswerRail-Fallback: origin-html`
  - `X-AnswerRail-Routing: fail-closed-origin-truncated | fail-closed-currency-shortfall | fail-closed-faq-recall-shortfall | fail-closed-link-recall-shortfall` (or `NextResponse.next()` in `answerrail/next` middleware; `502`/`504` if the upstream origin itself is unreachable).

### 2. RFC 9110 Representation Selection, Canonical Cache Key & 5-Tier `Cache-Control` Policy
- **Representation Selection (`detectAiCrawler` in `src/core/detector.ts`)**: Honors RFC 9110 `Accept` quality weights (`q=0` opt-out such as `text/markdown;q=0` always rejects Markdown; any UA sending an HTML-only `Accept` header without `*/*` or `text/*` receives HTML; `ChatGPT-User` browser sandboxes sending `Accept: text/html` without `text/markdown` receive HTML).
- **Zero User-Agent Cache Fragmentation & Header Hygiene (`createMarkdownCacheKey` in `src/services/cache.ts` & `fetchOrigin` in `src/core/fetcher.ts`)**: Responses include `Vary: User-Agent, Accept` for downstream RFC 9110 § 12.5.5 compliance, while Cloudflare edge cache storage keys are canonicalized to the exact runtime URL format:
  `https://cache.answerrail.internal/__ar_markdown_v1?target=<canonicalTarget>&lod=<compact|standard|deep>&mode=<twin|ast>[&schema=1]`
  where `&schema=1` is appended when `schema=true` or `lod=deep`. URL fragments (`#section`) are stripped, and all eligible AI retrieval crawlers share a single canonical cache entry per `(target, lod, mode, schema)` without fragmenting cache storage by raw `User-Agent` string, while `Googlebot` and human browsers never enter the Markdown cache path. Outbound `fetchOrigin` requests intentionally omit caller `Cookie`, `Authorization`, and `Accept-Language` headers so caller-specific credentials or locale preferences cannot leak or poison shared edge cache entries, and `Set-Cookie` is stripped on cacheable responses.
- **5-Tier HTTP `Cache-Control` Contract**:
  1. **Documentation & Specification Routes (`/vs/*`, `/security`, `/privacy`, `/research`, `/pricing`, `/llms.txt`)**: Emit `Cache-Control: public, max-age=60, must-revalidate` (60-second freshness window with mandatory revalidation on expiry, paired with `POST /api/purge` for immediate edge cache invalidation).
  2. **Compiled `/proxy` Markdown Responses (`computeDownstreamCacheControl` in `src/services/cache.ts`)**: Honor restrictive origin `Cache-Control` headers (`no-store`, `private`, `no-cache`) by returning `Cache-Control: no-store, no-cache, must-revalidate` (or `Cache-Control: public, max-age=0, must-revalidate` when origin `max-age=0`/`s-maxage=0`) and bypassing edge cache storage (`X-AnswerRail-Cache: BYPASS`); otherwise emit `Cache-Control: public, max-age=<min(14400, originTtl)>[, must-revalidate]` (defaulting to `Cache-Control: public, max-age=3600, must-revalidate` when origin specifies no TTL).
  3. **Fail-Closed Parity Fallback Responses (`src/routes/live-proxy.ts`)**: Emit `Cache-Control: no-store, no-cache, must-revalidate` and `X-AnswerRail-Cache: BYPASS`.
  4. **Next.js Middleware (`answerrail/next` in `src/middleware.ts`)**: Upstream `Cache-Control`, `ETag`, and `Age` headers are stripped and replaced with `Cache-Control: private, no-cache, no-store, max-age=0, s-maxage=0, must-revalidate` and `CDN-Cache-Control: no-store`.
  5. **Disallowed `robots.txt` Responses (`403 Forbidden` in `src/routes/live-proxy.ts`)**: Emit `Cache-Control: private, no-store` and `X-AnswerRail-Cache: BYPASS`.
- **Pre-Cache Per-Bot RFC 9309 `robots.txt` Enforcement (`checkOriginRobotsTxt` in `src/core/fetcher.ts`)**: Executed **before** `getOrSetEdgeCache`. Follows redirects manually (up to 5 hops) with per-hop `verifyResolvedHostSafety` (DoH DNS + IPv4/IPv6 CIDR + port 80/443 allowlist). Enforces RFC 9309 Section 2.3.1 status semantics (`2xx` parsed up to 500 KiB, `4xx` allow-all, `5xx`/unreachable disallow-all) and exact product-token group matching for both `AnswerRail-Edge-Proxy` and the delegated `requestingBot` (`X-AnswerRail-For-Bot`), ensuring a cached Markdown entry is never served to a disallowed crawler (`403 Forbidden by robots.txt`, `Cache-Control: private, no-store`, `X-AnswerRail-Cache: BYPASS`).

### 3. Asymmetric Ed25519 RFC 9421 Signing Architecture (`kid="ar_ed25519_2026_k1"`)
- **Published Public Key Directory (`https://answerrail.com/.well-known/http-message-signatures-directory` & `https://answerrail.com/.well-known/answerrail-proxy.json`)**:
  ```json
  {
    "keys": [
      {
        "kty": "OKP",
        "crv": "Ed25519",
        "kid": "ar_ed25519_2026_k1",
        "x": "W3Ce5nykyharINhDTj_EL5JtdEkz0_bcXrDsDN-vy3Y",
        "use": "sig",
        "alg": "EdDSA",
        "key_ops": ["verify"],
        "ext": true
      }
    ]
  }
  ```
- **Private Key Isolation, Provenance Scope & Replay Protection (`src/services/provenance.ts`)**: The Ed25519 private key (`d`) resides exclusively in Cloudflare Worker secret storage (`ED25519_PRIVATE_KEY_JWK`) and is never present in source code or derived from public strings. Signatures attest **AnswerRail edge compilation provenance** (that the response body was compiled and parity-checked by AnswerRail's edge worker from `origin_url`, not third-party origin authorization). Both signing operations use WebCrypto `Ed25519`, `keyid="ar_ed25519_2026_k1"`, `alg="ed25519"`, a 300-second replay window (`created=<unix_s>;expires=<created+300>`), and a 16-byte CSPRNG `nonce` (`crypto.getRandomValues(new Uint8Array(16))` with bounded stateful single-use replay rejection via `checkAndRecordReplayNonce`):
  - **Operation A — Outbound Origin Subrequest Signing (`signOutboundOriginRequest`, `tag="web-bot-auth"`)**: Signs outbound proxy subrequests to origin servers over the 5-component set:
    `Signature-Input: sig1=("@method" "@authority" "@target-uri" "signature-agent" "x-answerrail-timestamp");created=<unix_s>;expires=<created+300>;nonce="<16B_base64url>";keyid="ar_ed25519_2026_k1";alg="ed25519";tag="web-bot-auth"`
  - **Operation B — Compiled Markdown Response Provenance Signing (`generateProvenanceHeaders`, `tag="answerrail-response-provenance"`)**: Signs compiled Markdown responses returned to callers over the 2-component set using RFC 9421 § 2.4 `@target-uri;req`:
    `Signature-Input: sig1=("content-digest" "@target-uri";req);created=<unix_s>;expires=<created+300>;nonce="<16B_base64url>";keyid="ar_ed25519_2026_k1";alg="ed25519";tag="answerrail-response-provenance"`
    where `content-digest` is the RFC 9530 SHA-256 digest (`sha-256=:<base64>:`) of the exact response body. On edge cache `HIT` (`getOrSetEdgeCache` in `src/services/cache.ts`), when `cache_age_seconds` is updated in YAML frontmatter, stale `Signature-Input`, `Signature`, and `X-AnswerRail-Signature` headers are deleted before invoking `reSignFn`; if `reSignFn` throws or is unconfigured, stale signatures remain stripped and `Content-Digest` / `X-AnswerRail-Content-SHA256` are recomputed directly for the updated body.

## Frequently Asked Questions
### What is the difference between Scrunch AI, Scrunch AXP, and AnswerRail in 2026?
Scrunch AI ($250–$500/mo) is an observation-only dashboard that monitors prompts and personas without modifying your website. Scrunch AXP ($20,000–$60,000+/yr) is an enterprise CDN integration (partnered with Sitecore) that serves streamlined HTML to bots. AnswerRail ($0 Free · $99/mo Starter) includes both 6-Engine Visibility/Citation-Gap analytics AND an active 330+ PoP Anycast Markdown edge proxy in a single self-serve subscription.

### Why serve pure Linkedom AST Markdown (GFM) instead of Scrunch AXP’s streamlined HTML?
Even stripped HTML wastes 30%–50% of retrieval tokens on opening/closing angle brackets and nested wrapper tags. Compiling to GitHub-Flavored Markdown (GFM) with Byte-0 Schema.org tables fits 100% of your pricing tiers, technical specs, and unrolled FAQ answers inside Perplexity and ChatGPT Search’s 25,000-token context window.

### How much does AnswerRail cost compared to Scrunch AI ($250–$500/mo) and Scrunch AXP ($20k+/yr)?
AnswerRail provides a $0 Forever-Free 6-Engine AI Visibility Tracker and Readiness Grader. Paid self-serve plans start at $99/mo ($79/mo billed annually) for 1 production domain with unlimited team seats, $249/mo for 5 domains, and $599/mo for 35 agency client domains—saving over 90% compared to enterprise AXP contracts.

### How does AnswerRail’s 100% FactCheck Recall Gate prevent price hallucinations?
Before emitting or caching any Markdown page, AnswerRail runs a converter-independent static reference check (extractIndependentStaticReference) directly against raw origin HTML. If even one price token (such as split <span>$</span><span>99</span> spans), collapsed FAQ answer, or main-content link is missing, AnswerRail fails closed to unmodified origin HTML (X-AnswerRail-Failsafe: FAIL_CLOSED_ORIGIN_HTML).

### Can non-Sitecore websites (Next.js, Shopify, WordPress, Webflow) deploy AnswerRail in 60 seconds?
Yes. AnswerRail is 100% platform-agnostic: paste one <script src="https://answerrail.com/ai-attribution.js" defer></script> tag into Shopify, WordPress, Webflow, or Google Tag Manager in 60 seconds, add answerrail/next middleware on Vercel, or point a guided CNAME to edge.answerrail.com.
