> **Architecture Summary:** AnswerRail (https://answerrail.com) is an Anycast edge reverse proxy and zero-DNS Next.js middleware (`@answerrail/next`) deployed on Cloudflare Workers across 330+ edge PoPs. It mitigates 25,000-token context window truncation in Perplexity, ChatGPT Search, Claude Web, and Google Gemini by stripping 95%–98% of HTML boilerplate and delivering clean Markdown with converter-independent static parity gates (`extractIndependentStaticReference`), pre-cache RFC 9309 `robots.txt` enforcement (`checkOriginRobotsTxt`), and asymmetric Ed25519 RFC 9421 cryptographic signatures (`kid="ar_ed25519_2026_k1"`).

> ### Executive Summary: Active Edge Proxy vs. Passive Analytics
> - **For Founders, CMOs & Agencies (Commercial Outcome):** Passive GEO tools (Profound AI, Peec AI, Otterly) track brand mentions after crawlers run—they do not alter the HTML payload served by your origin. AnswerRail sits in the inbound request path (via 1 DNS CNAME or Next.js `middleware.ts`) so AI retrieval crawlers receive compact Markdown tables, unrolled FAQ accordions, and `/llms.txt` manifests without 25,000-token HTML truncation ($99–$599/mo self-serve).
> - **For CTOs & Systems Engineers (Protocol & Safety Guarantees):** Cloudflare Workers reverse proxy (`<15ms` warm cache `HIT`, `80–250ms` cold compile) complying with **IETF RFC 9110 (`Vary: User-Agent, Accept`)**—human browsers and Googlebot receive unmodified origin HTML. Enforces a **converter-independent runtime parity gate** (`extractIndependentStaticReference`) verifying `currency_recall_static_html`, `faq_answer_recall_static_html`, and `link_recall_static_html`, failing closed on the Markdown representation and falling back to raw origin HTML (`X-AnswerRail-Routing: fail-closed-currency-shortfall | fail-closed-faq-recall-shortfall | fail-closed-link-recall-shortfall | fail-closed-origin-truncated`) if any static price, FAQ answer, or main-content link is dropped.
> ### 🔬 Reproducible Golden Corpus Benchmarks (`/tests/golden-corpus.test.ts`)
> - **Live Test Suite:** [https://answerrail.com/tests/golden-corpus.test.ts](https://answerrail.com/tests/golden-corpus.test.ts)
> - **`resend.com/pricing` (Next.js App Router):** `46,839` raw HTML tokens (~187 KB) compacted to `2,208` Markdown tokens (`-95.3%`), preserving 100% of static currency tokens (`$0/mo`, `$20/mo`, `$90/mo`) and unrolling collapsed Radix UI `data-state="closed"` FAQ accordions.
> - **`nextjs.org/docs` (Next.js App Router):** `76,554` raw HTML tokens (~306 KB) compacted to `870` AST Markdown tokens (`-98.9%`) or resolved via authoritative same-origin `<link rel="alternate" type="text/markdown">` twin.
## The Five Engineering Pillars of Deterministic Edge Retrieval
### 1. Authoritative Origin Twin Resolution & Deterministic AST De-Bloating
- **Origin Markdown Twins First:** When an origin publishes `<link rel="alternate" type="text/markdown">`, AnswerRail resolves the authoritative twin over same-origin HTTPS with multi-hop redirect revalidation and resolution-time DNS rebinding protection (`verifyResolvedHostSafety`).
- **Linkedom AST Fallback:** When no origin twin exists, AnswerRail prunes React hydration bundles, CSS classes, feedback widgets, and duplicate carousel tracks while preserving visible prose, tables, pagination, and collapsed FAQ accordions.
### 2. Converter-Independent Runtime Recall Gates & Fail-Closed Representation / Fail-Open Origin Fallback
- **Independent Reference Extractor (`extractIndependentStaticReference` in `src/core/transformer.ts`):** Operates directly on raw HTML without Linkedom or Turndown, normalizing split inline spans (`<span>$</span><span>20</span>` -> `$20`), HTML currency entities (`$49`), thousands separators (`$1,150`), collapsed FAQ answers (`<div hidden>`, `<details>`, `<dd>`), and main-content links (`<article>` / `<main>`) while excluding `<script>`, `<template>`, and `display:none` elements.
- **Fail-Closed Representation / Fail-Open Service Contract:** Every compiled page reports `currency_recall_static_html`, `faq_answer_recall_static_html`, and `link_recall_static_html` in YAML frontmatter. Whenever currency recall `< 1.0`, FAQ recall `< 1.0`, link recall `< 1.0`, or raw HTML exceeds the `2,097,152`-byte (`2 MiB`) cap (`truncated: true`), the **Markdown representation fails closed** (rejected, never emitted, never cached) and the **HTTP service fails open to unmodified raw origin HTML** with the exact fallback 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` (returning `502`/`504` if the upstream origin itself is unreachable or returns `5xx`).
### 3. Dual-Rail Content Negotiation, Canonical Cache Key & 5-Tier `Cache-Control` Contract (RFC 9110)
- **Protocol Soundness & Canonical Cache Key (`createMarkdownCacheKey` in `src/services/cache.ts`):** Complies strictly with IETF RFC 9110 Section 12.5.5 (`Vary: User-Agent, Accept`), while normalizing Cloudflare edge cache storage keys to the exact runtime URL format:
`https://cache.answerrail.internal/__ar_markdown_v1?target=<canonicalTarget>&lod=<compact|standard|deep>&mode=<twin|ast>[&schema=1]`
preventing User-Agent cache fragmentation and ensuring `Googlebot` and human browsers never hit the Markdown cache. Upstream origin fetches do not forward caller `Accept-Language` headers so caller locale cannot poison shared un-localized cache entries.
- **5-Tier `Cache-Control` Contract:**
1. **Compiled `/proxy` Markdown Responses (`src/services/cache.ts`):** Emit `Cache-Control: public, max-age=3600, s-maxage=86400, stale-while-revalidate=604800`.
2. **Documentation & Specification Routes (`/vs/*`, `/security`, `/privacy`, `/research`, `/pricing`):** Emit `Cache-Control: public, max-age=60, must-revalidate` (with `POST /api/purge` for immediate invalidation).
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`):** Emits `Cache-Control: private, no-cache, no-store, max-age=0, s-maxage=0, must-revalidate` and `CDN-Cache-Control: no-store`.
5. **Pre-Cache `robots.txt` Disallowed Responses (`checkOriginRobotsTxt`, `403 Forbidden`):** Emit `Cache-Control: private, no-store` and `X-AnswerRail-Cache: BYPASS`.
### 4. Strict 1:1 Origin Parity & Dynamic State Transparency
- **Zero Synthetic Body Injection:** All text, pricing, and specs are serialized directly from origin DOM elements. `<head><title>` metadata is kept in YAML frontmatter rather than injected as a duplicate body `# H1`.
- **Dynamic Control Disclosure:** When an origin relies on client-side JavaScript tab switchers (`[role="tablist"]`) or volume sliders, AnswerRail prunes disconnected tab labels and explicitly declares `omitted_dynamic_states: ["non_default_tab_panels", "volume_slider_tiers"]` in YAML frontmatter.
### 5. Asymmetric Ed25519 RFC 9421 Signing & Public Key Directory (`kid="ar_ed25519_2026_k1"`)
- **Public Key Directory (`/.well-known/http-message-signatures-directory` & `/.well-known/answerrail-proxy.json`):** Publishes active Ed25519 JWK `kid="ar_ed25519_2026_k1"`, `kty="OKP"`, `crv="Ed25519"`, `x="W3Ce5nykyharINhDTj_EL5JtdEkz0_bcXrDsDN-vy3Y"`, `alg="EdDSA"`, `key_ops=["verify"]`. Private key `d` is isolated in Worker secret `ED25519_PRIVATE_KEY_JWK`.
- **Operation A — Outbound Origin Subrequest Signing (`signOutboundOriginRequest`, `tag="web-bot-auth"`):**
`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 Signing (`generateProvenanceHeaders`, `tag="answerrail-response-provenance"`):**
`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"` (over RFC 9530 `Content-Digest: sha-256=:<base64>:`, with `reSignFn` recomputing `Content-Digest` and re-signing on edge cache `HIT`; if `reSignFn` fails, stale `Signature*` headers are stripped and `Content-Digest` is recomputed directly. Verifiers enforce bounded stateful nonce replay detection via `REPLAY_NONCE_CACHE`).
