Trusted Collaboration Tunnel (TCT)

Efficient, verifiable content delivery for AI crawlers. Reduce bandwidth by 83%, tokens by 86%.

The Trusted Collaboration Tunnel protocol enables efficient machine-readable content delivery through bidirectional discovery, template-invariant fingerprinting, and sitemap-first optimization. Patent-pending (US 63/895,763).

Measured Results from 970+ Production URLs

How It Works: 4-Part Protocol

1. Bidirectional Discovery

• C-URL contains: <link rel="alternate" type="application/json" href="M-URL">
• M-URL responds: Link: <C-URL>; rel="canonical"
• Verifiable handshake prevents URL guessing

2. Template-Invariant Fingerprinting

• Content normalized (strip HTML, CSS, JS)
• SHA-256 hash → ETag header
• Same content = same hash, regardless of theme changes

3. Conditional Request Discipline

• Client sends: If-None-Match: "sha256-abc123..."
• Server responds: 304 Not Modified (zero body)
• 90%+ of requests skip full fetch

4. Sitemap-First Verification

• /llm-sitemap.json lists all URLs + hashes
• Client compares local cache vs sitemap
• Only fetch changed content
• Zero-fetch optimization

Production Sites (100% Compliant)

• wellbeing-support.com (400 URLs, 10/10)
• galaxybilliard.club (500 URLs, 10/10)
• bestdemotivationalposters.com (500 URLs, 9/10)
