Apply CQRS (Command Query Responsibility Segregation) and Event Sourcing fordomains requiring strong auditability and independent scaling of reads and writes.Triggers: CQRS, event sourcing, audit trail, event replay, read/write separation,temporal queries, event store, projections, command handlers, aggregate rootsUse when: read/write workloads have different scaling needs, complete audit trailrequired, need to rebuild historical state, temporal queries ("state at time X")DO NOT use when: selecting from multiple paradigms - use architecture-paradigms first.DO NOT use when: simple CRUD without audit requirements.DO NOT use when: team lacks experience with eventual consistency patterns.Consult this skill when implementing event sourcing or CQRS patterns.
