Overview

This architecture pack captures the runtime shape of the D4L platform: who interacts with it, how contracts and services compose, and how lifecycle events move through the system.

How to read

  • Start with system context and containers to align on boundaries.
  • Review contract components and permissions to understand on-chain authority.
  • Use the state machine and sequence diagrams to reason about lifecycle behavior.
  • Confirm event mappings before implementing indexing or analytics.
