 # ChittyOS
 
-> Operating System & Infrastructure
+**Trust infrastructure and intelligent operating system for verification, identity, and evidence.**
 
-Building next-generation operating system and infrastructure components
+ChittyOS is a distributed platform of Cloudflare Workers powering identity resolution, evidence processing, trust scoring, and service orchestration across the Chitty ecosystem.
 
-## Focus Areas
+## Architecture
 
-- **Operating Systems**
-- **System Software**
-- **Infrastructure**
-- **Developer Tools**
+Services are organized by tier, where lower tiers have no upstream dependencies:
 
-## Our Repositories
+| Tier | Services | Purpose |
+|------|----------|---------|
+| **0** | ChittyID, ChittyTrust, ChittySchema | Trust anchors — identity, trust resolution, schema governance |
+| **1** | ChittyAuth, ChittyCert, ChittyRegister | Core identity — authentication, certification, service registration |
+| **2** | ChittyConnect, ChittyRouter, ChittyAPI | Platform — API gateway, MCP server, intelligent routing |
+| **3** | ChittyMonitor, ChittyTrack, ChittyBeacon | Operational — observability, logging, distributed tracking |
+| **4** | ChittyEvidence, ChittyIntel, ChittyScore | Domain — evidence processing, intelligence, scoring |
+| **5** | ChittyCases, ChittyDashboard, ChittyCommand | Application — case management, dashboards, automation |
 
-Explore our projects organized by purpose and technology:
+Every service exposes a health endpoint at `https://{service}.chitty.cc/health` and follows the compliance triad: `CHARTER.md` (contract) + `CHITTY.md` (architecture) + `CLAUDE.md` (dev guide).
