PURE LIGHT LTD · SOFTWARE & AI ENGINEERING
Edge Execution Chassis.Purpose-Trained Models.Engineered Properly.
Pure Light Ltd is a UK software engineering firm operating a unified Edge Execution Chassis. We deploy composable production modules directly at the CDN boundary: powering autonomous technical SEO, continuous compliance, and AI agent governance.
Backed by our in-house model foundry, we build purpose-trained AI with proprietary datasets, rigorous anti-slop validation, and edge-native economics. Every layer is fail-open by design. We power strategic, white-label partnerships for global tech platforms.
01 / CHASSIS ARCHITECTURE
The chassis beneath the signal.
Three primitives. One composable foundation for software that stays fast when the world gets noisy.
02
Fail-Open Infrastructure
Zero-risk architectural contracts: if the edge layer ever hiccups, origin traffic passes unimpeded. Zero White Screen of Death liability.

fail-open safety contract

Autonomous Agent Firewalls
Graduated response ladders and cognitive de-escalation protocols designed to contain, sandbox, and govern autonomous AI agent fleets.

ONE CHASSIS · THREE PRODUCTION MODULES
One chassis.
Every module built, operated, and proven in production.
We do not build speculative prototypes. Every module below is an active, production-grade layer of the same edge execution chassis, not a disconnected portfolio of apps, demonstrating our technical depth and commercial viability.
01 / LEAD MODULE / HOSTING AUTOMATION / AUTONOMOUS SEOLIVE / v1.4.0
Cleo SEO
Lead Module · Autonomous Edge SEO Operator for Cloudflare & WordPress
The chassis flagship. Engineered specifically for hosting provider partnerships and white-label integration, Cleo intercepts streaming responses at the CDN edge to inject structured data, purge page-builder cruft, and fix technical SEO without origin PHP plugins, with strict WooCommerce dynamic-path bypass and a 50ms fail-open transform contract.
- Edge HTMLRewriter stream interception in sub-5ms with zero origin load
- Strict dynamic-path bypass: cart, checkout, my-account, wp-admin and wc-ajax are never cached or transformed
- Origin Shield fail-open snapshot fallback preventing 502/504 errors
- Automated Google rich snippets for WooCommerce, Elementor, and Divi

AI Agent Governance Layer · Edge Execution Firewall
The next layer of the chassis: a graduated edge response layer for autonomous AI systems. Protects origin servers, APIs, and databases from rogue agents, prompt injection swarms, and uncoordinated autonomous actions without triggering trapped-fox evasion.
- 5-Rung De-escalation Ladder (Shadow → Re-anchor → Degrade → Parley → Kill)
- Cognitive Judo protocol pretexts preventing agent evasion
- Zero-leak streaming canary transform & Durable Object swarm correlation
- Drop-in 1-line OpenAI SDK proxy compatibility (base_url)

MODEL FOUNDRY · THE MOIRAI FAMILY
Three fates. One foundry.
Purpose-trained models · spun, measured, and cut in-house.
Most AI prose carries the same synthetic fingerprints: repetition, negation stacks, echo finales, and summary endings. We engineered the antidote. Our models are built on proprietary preference datasets and ruthlessly validated against our open slop-detection methodology before a single token is served. The evidence is public: across the published A/B, Clotho scores 0.0; the base model it was trained from scores 0.6.

Narrative & Roleplay
Spins the prose without the tells.
The launch model of the family: quiet, concrete, atmospheric prose with a dry sense of humour. A 7B narrative fine-tune built to remove the clichés, loops and summary endings generic models cannot shake.
- 32,768-token context, live-verified end to end
- Slop Index 0.0 in the published A/B (base model: 0.6)
- OpenAI-compatible: works in any client with zero setup

Editorial & Content
Measures every word.
The editorial Fate: human-feeling marketing and web copy that reads like a person wrote it. Trained against our open human-tells taxonomy, it writes reviews, guides and landing copy with rhythm, honesty and restraint.
- Written for conversion copy, reviews and long-form
- Fractions of a penny per article at the edge

THE OPERATOR
Built and operated by its founder.
Pure Light Ltd is led by Founder & Director G. Butterworth.
Based in the UK, he is a hands-on technical operator who designs, ships, and maintains every system featured here: from edge engines to the in-house model foundry.
His work sits at the intersection of engineering and growth. Rather than managing from a distance, he stays close to the stack, building the infrastructure, automation pipelines, and applied AI systems that help startups scale.
Banking-Grade Rigour: As a Member of the London Institute of Banking & Finance (MLIBF), he brings a highly analytical approach to software economics. If a metric matters to the business, it gets tracked and optimised.
Remote Leadership: He leads distributed teams the same way he builds software: with clear contracts, high standards, and a focus on delivery.
Built to Hand Over: A qualified educator and former cybersecurity teacher, he prioritises zero-friction execution. Teaching keeps the fundamentals sharp, which translates directly into how he documents, explains, and hands over technical systems.
