Validation

Sruja validates your model to catch issues early.

Common Checks

• Unique IDs within scope
• Valid references (relations connect existing elements)
• Cycles (informational; feedback loops are valid)
• Layering violations (dependencies must flow downward)
• External boundary checks
• Simplicity guidance (non‑blocking)

Example

import { * } from 'sruja.ai/stdlib'


User = person "User"
App = system "App" {
  WebApp = container "Web App"
  API = container "API"
  DB = database "Database"
}

// Valid relations (qualified cross-scope)
User -> App.WebApp "Uses"
App.WebApp -> App.API "Calls"
App.API -> App.DB "Reads/Writes"

view index {
include *
}

Run sruja validate locally or in CI to enforce these rules.
