Tactical Pattern Checklist

Aggregate design

• One aggregate root per transaction boundary
• Invariants enforced inside aggregate methods
• Avoid cross-aggregate synchronous consistency rules

Value objects

• Immutable by default
• Validation at construction
• Equality by value, not identity

Repositories

• Persist and load aggregate roots only
• Expose domain-friendly query methods
• Avoid leaking ORM entities into domain layer

Domain events

• Past-tense event names (for example, OrderSubmitted)
• Include minimal, stable event payloads
• Version event schema before breaking changes
