# Codexel — Full Technical & LLM Reference Corpus (llms-full.txt)

> Complete, citation-ready specification of the Codexel AI Web Platform, 2026 7-Layer Search & Agent Optimization Taxonomy, and Machine-Transactable Agent Endpoints.

## 1. Platform Architecture
- **Visual Design Studio & Multimodal Cloning**: Converts screenshots and live URLs into responsive component trees with SSRF-protected scraping and Gemini 3.8 multimodal vision.
- **Site Factory & Fleet Manager**: Generates, deploys, backs up (AES-256-GCM encrypted), and A/B-tests fleets of domain-mapped websites from a unified control plane.
- **Dynamic OpenGraph Engine**: Generates crisp 1200x630 vector OpenGraph cards on demand at `/api/og?title=...&subtitle=...`.

## 2. The 2026 7-Layer Search & Agent Optimization Taxonomy
1. **SEO (Search Engine Optimization)**: Crawlability, canonical URLs, XML sitemaps, Core Web Vitals, mobile responsiveness.
2. **AEO (Answer Engine Optimization)**: Direct answer blocks, `FAQPage` & `HowTo` JSON-LD, `SpeakableSpecification` for voice & featured snippets.
3. **GEO (Generative Engine Optimization)**: E-E-A-T authority signals, verifiable statistics, `Organization`/`LocalBusiness` `sameAs` entity graphs for AI Overviews, Perplexity, and ChatGPT Search.
4. **LLMO (Large Language Model Optimization)**: Clean semantic Markdown via `/llms.txt` and `/llms-full.txt`, unambiguous entity naming, RAG-quotable fact blocks.
5. **SXO (Search Experience Optimization)**: High-contrast accessible UI, sub-second interaction latency, clear conversion CTAs, sticky two-tailed A/B experimentation.
6. **AXO / AAO (Agent Experience / Assistive Agent Optimization)**: Machine-transactable `/.well-known/agent.json`, Schema.org `potentialAction` (`ReserveAction`, `CommunicateAction`, `SearchAction`), and structured JSON APIs.
7. **AIO (AI Optimization — Composite Score)**: Weighted holistic readiness index across all 6 foundational layers.
