The capstone is a monitoring-policy system for a team that needs to register rules, activate them deliberately, evaluate incoming metric samples, emit incidents, and keep downstream read models in sync without turning the domain model into procedural glue.

Use this guide to keep the capstone question-first. The repeated study goal is simple: if this behavior changed tomorrow, which object or boundary should absorb that change, and why?

What this capstone proves

  • value objects can keep domain facts explicit and stable
  • an aggregate can own lifecycle transitions and incident decisions directly
  • strategies can carry evaluation variability without bloating the aggregate
  • events and projections can keep derived views downstream of authoritative state
  • runtime orchestration can stay outside the domain while still coordinating real work

Start by module range

Module range Best capstone focus
Modules 01-03 value semantics, lifecycle rules, and aggregate state transitions
Modules 04-07 policies, events, repositories, runtime coordination, and boundary ownership
Modules 08-10 tests, bundles, public routes, and extension seams

Guide set

Review questions

  • Which object owns each invariant?
  • Which objects are authoritative, and which are only derived views?
  • Where would a new rule mode, sink, or projection belong without weakening ownership?

Stop here when

  • you know which object or boundary the current chapter is really about
  • you know which file or bundle makes that ownership visible
  • you know the smallest command that proves it
