 ## High-Level Architecture
 
 ### Platform Overview
 
 The Pulumi platform consists of two primary architectural components: a client-side command-line interface and a
 multi-tenant cloud service infrastructure. These components work in concert to provide a complete infrastructure

 Deployment orchestration represents a critical functional domain within the platform. When users initiate infrastructure
 operations, requests are queued and subsequently processed by specialized execution components. These components operate
 in isolated execution environments, pulling the latest infrastructure code, applying the requested changes against cloud

 The platform employs a multi-layered data storage strategy optimized for different access patterns and data

 ## Cryptographic Architecture
 
 ### Encryption Key Hierarchy
 
 The platform implements a sophisticated three-tier key hierarchy that separates key management responsibilities and
 enables flexible key rotation without requiring re-encryption of all data. At the top of the hierarchy are key
-encryption keys, which are never stored unencrypted within the platform's data stores. These keys reside in external key
